Prostate Cancer Site Map
This web paper is dedicated to the memory of my wife of 43 years, Barbara Cohen
(24 August 1945 -- 11 July 2016).
It was Barbara's intuition that mothers' milk could fight cancer and her web
research that turned up the first article for us in August 1999, that started
my healing journey and which resulted in this web site. In addition, it was her
way with people that led to my first receiving milk from a donor and to my
later being able to purchase milk from a Milk Bank.
Some of this story will unfold as you read this paper.
It was her love and support, her intuition, insights and comfort with people,
that led to the so far happy conclusion of my cancer story. Twenty four years
after diagnosis (September 2023) I have no detectable cancer without any medical
interventions beyond non-invasive diagnostics. She will be sorely missed.
Read on for more details.

On 4 November 1999 I gave a talk based on the accompanying slides to the
Silicon Valley (California) Prostate Cancer Support Group at one of their
monthly meetings at El Camino Hospital in Mountain View. Since then I have
been asked a number of times for the information in my talk. But, since it
was not written down, I had to reinvent it, in abbreviated form, each time.
This is my attempt to flesh in the details and history "once and for all".
That is, to write it down in a more complete and narrative style than the
slides and also to have a base for keeping my story current, as time and
my medical history evolve.
This is a living, evolving document, with continual minor changes, new
references, new test results, and ocassional major revisions and
additions, although it is based on that talk of hope in November 1999.
On 3 November 2016, almost 17 years later to the day, I gave an update talk
to the same Silicon Valley Prostate Cancer Support Group at El Camino Hospital
in Mountain View, California.
A link to both the original 1999 slides and the 2016 slides are noted above.
Here I seek to accomplish a number of things. This paper is
- My story as a narrative
- An external memory and compilation of my test results and experiences
- A tutorial on prostate cancer
- A tutorial on MRSI as an imaging technology
- A tutorial on the effects of human mothers' milk on cancer
- An extensive bibliography with many downloadable peer reviewed
scientific papers and links
I put significant effort into researching and understanding prostate cancer
and HAMLET in the first years after my diagnosis, including the bulk of the
effort in putting this web page together. During the dot-com (and high tech
and biotech) bust of 2003-2004, my focus changed to economic survival. And
then as the economy improved and my cancer became undetectable, I have
spent less effort in trying to keep up to date than I did initially.
What I am doing seems to be working and, while I acknowledge prostate
cancer and my need to be sure it remains undetectable, I do not want it
to dominate my life.
I keep my personal story and test results up to date and add references and
discussions as I come across them (either in my travels around the web or
via prostate cancer newsletters or references kindly forwarded to me by
friends, acquaintances or strangers). I suggest that the reader may use this
as a starting point for his/her research but to bring your searches up through
the current state of the art, as many of the references herein are, perforce,
dated or obsolete, since this web site has been growing for over two
decades and cruft accumulates (or events continue evolving).
And I wish you all good health, a positive attitude and much support.
[A Note to the Reader]
I would welcome feedback
and dialog on the material presented here.
This could range from typos to infelicities of expression to areas
that are unclear or which you might desire a more detailed
exposition. Also, corrections to factual or reference material or
additional items or issues you think I should know about. And, as
always, kudos are welcome as well.

I was trained as a scientist, hence a skeptic to unfounded claims. I
received a Ph.D. in theoretical physics when the job market for academics
was rapidly disappearing in the mid-1970's, and switched into the
nascent field of software engineering and computer programming early on
after graduate school.
Most of the work I have done professionally has involved some sort of
scientific or engineering applications (see
my web pages for details), including
the past several years (since late 1996) in biotechnology and genomics.
With this all, I can claim scientific literacy and an analytical approach,
a belief that I can master most areas of knowledge, and a sense of numeracy,
an appreciation of numbers and statistics. While I have not had much training
in biology and none in medicine, I was able to educate myself about prostate
cancer and the available treatment modalities in a very intense couple of
months immediately after my diagnosis.
I was diagnosed in July 1999, just before my 54'th birthday. I have
always been quite healthy, in reasonably good physical condition, slim,
and with a good diet.
And I have usually had a take-charge attitude with regard to my own
well-being. I view doctors as partners, well trained technicians who should
be working for me and with me. I have little regard for those who try to
elevate themselves to god-like status or view their patients/clients as
slabs of meat to be treated as objects rather than as people with whom they
are collaborating. The ultimate responsibility for my health lies with me.
And finally, I have humility in the face of cancer. It is a very serious
disease (or set of diseases) with extremely serious consequences and should
not be denied, ignored, or trifled with. Being diagnosed was a great shock
that was counter to the myth I have lived by, that of Good Health and
Immortality (which really translates to a long and healthy life). And it
took a little while to hear the diagnosis and its implications and to
mobilize myself in the midst of the rest of my life.
The following table describes the evolution of my PSA
levels with time. This data is also graphed below. All PSA values have been
determined at Stanford Hospital unless otherwise noted. In mid-2001, Stanford
changed the test used to give an extra significant figure in the results.

In about 1993, a friend of mine who was just 50 at the time, was diagnosed
with prostate cancer. His PSA was about 142 when diagnosed (normal range
is 0.0 to 4.0 ng/ml) and 180 when he received a radical prostatectomy
at Stanford University Hospital by the fabled Dr. Freiha, who has since
retired and then resumed practice at the Palo Alto Veterans' Administration
hospital. Since then, my friend had been on and off hormone therapy and
seemed to have his cancer under control. (In late 2005, after 12 years of
intermittant hormonal blockade [which will be discussed in
Appendix B], he developed hormone refractory prostate cancer
and explored chemotherapy options. He tried mothers' milk briefly in
2007. He died of prostate cancer in June 2008, surviving 15 years, although
he was only given one to two years to live at his initial diagnosis.)
I thought that his cancer might be correlated with his work and where he
has been living for some time. My impression is that the synthetic
estrogenergic chemicals used in pesticides and herbicides by agribusiness
to increase their yields and profits at the expense of the health of farm
workers and the rest of us is correlated with the sharp rise of breast and
prostate cancer in the decades since the Second World War. (See
reference, below). And my friend
was involved in the food processing industry and lived in lovely rural areas
where heavy industrial agriculture took place. I thought his exposure was
probably higher than normal, hence a likely contributor to the cancer. I don't
know if the epidemiology supports this or not, yet we are all, urban and
rural, exposed to enormous amounts of toxic and teratogenic chemicals in
our air, water and food, things to avoid, yet things impossible to avoid.
I have also found out that he has a genetic predisposition, since his
father and uncle have had prostate cancer. There have been no cases I
know of in my family except an uncle who had a mild case in his mid-80's
(he had brachytherapy and lived to 96).
But somehow, I thought I was immune. Even so, in my periodic physicals, I
had to insist that my physician do a PSA test in addition to the usual
DRE (digital rectal exam, where a gloved finger
probes for irregularities on the back wall of the prostate gland).
The PSA's were normal. The last normal one was in December of 1997, when it
was 1.9 ng/ml.
In late April 1999, I had another "annual" physical. The PSA came back as 5.4
ng/ml. This was alarming for two reasons. First, the absolute number was
above the "normal" range of 0.0-4.0 ng/ml. And second, the rate of increase
seemed rather steep. This is also a sign that there is a cancer that
is beginning to grow rapidly. In fact, a conservative estimate of the growth
rate is to assume that it was linear and started just after the last "normal"
reading. In that case, in these 16 months it increased by 3.5 ng/ml, which is a
rate of 0.21875 ng/ml/month. If it started increasing (linearly) after
that time, its rate of increase must have been even higher.
[Aside about PSA]
I should probably say a few words about what PSA is and what it isn't.
It stands for Prostate Specific Antigen, a particular chemical that seems
only to be secreted by prostate cells. It is often a proxy for prostate
cancer, but not always. Men can have prostate cancer with low or normal
PSA levels. Conversely, a high level may not mean cancer but may be the
result of an infection of the gland (prostatitis) or a benign enlargement
of the gland (BPH, benign prostate hyperplasia),
which often occurs in older men and frequently leads to urinary problems.
In addition, the PSA in normal men fluctuates naturally. It increases for
two or three days after ejaculation (by roughly 10-15%, according to
Professor Peter Carroll, UCSF, personal communication, 29 May 2001)
or any disturbance of the gland. The
medical literature indicates that you can expect
PSA levels to fluctuate about 10-15% normally. And the lab results are
also not that reproducible; different labs have their own biases. Even
drawing blood and dividing it into two samples which are then sent to the
same lab may produce results 10-15% apart. So what one looks for is long
term trends, averaging out the fluctuations. And more frequent measurements
allow the fluctuations to be seen and the trends to emerge from the data,
as is true for any statistics.

It took until mid-June to get an appointment with a urologist at Stanford,
one recommended by my physician, also at Stanford. We chatted and he
recommended an ultrasound (TRUS, a trans-rectal
ultasound), combined with a
biopsy, which was scheduled for early July. With the TRUS, an ultrasound probe
is inserted in the anus and moved around. It creates crude images of
the interior of your pelvis, especially of the prostate gland. I couldn't
see much there, but a trained radiologist (ultra-soundist?) can see
abnormalities in the organ and surrounding tissues, if they are bigger than
some minimum (and crude) resolution. The prostate volume can also
be measured, which helps in determining whether there is enlargement due
to BPH or other conditions.
My TRUS showed nothing out of the ordinary.
At the same time, the ultrasound probe can be used for taking biopsy samples.
The ultrasound image can guide the doctor to point the tip to particular
locations on the gland (for example, left upper, left mid, left lower,
etc.). A spring loaded hollow needle can be fired through
the rectal wall into the prostate to draw a cell sample about 1 mm in
diameter and 10 to 15 mm long. These samples are stained, fixed, and sent
to a pathology lab for examination under a microscope. The procedure takes
maybe 15 minutes. It is uncomfortable and unpleasant but tolerable. In my
case, 10 samples were taken.
A week and a half later, my wife and I went to meet the urologist at
Stanford for the results. In my first two visits, he was punctual,
pleasant, if drabbly efficient. This time, the bean counters at the
hospital, in their increasing quest for milking money from both doctors and
patients, had overbooked him, and he was over an hour late getting to see
us. This was creating problems since my wife had clients of her own to see
that afternoon, and I had business obligations. We were not pleased when
he finally had time for us, with a couple of residents hanging out in the
back of the room to observe.
The results were kind of ambiguous. The Pathology Department had seen nothing
awry in the samples. The Urology Department pathologist (Dr. John McNeal, a
world-class master of the art of reading and interpreting slides) had
re-examined them and found that in one core from the left midsection, there
was a 1 mm square region that seemed as if the cells might be cancerous. I
was to come back for some additional sampling in that region.
As soon as he said that, I stopped being able to hear. I was stunned by the
news and furious at our mistreatment. He must have talked for a while longer,
but I did not remember what he said. I made an appointment for the next
week, when 4 more cores were taken from the left-midsection. The results
came via a phone call on 27 July: one of these also had a 1 mm square
group of cancer cells. The Gleason score was 3+3, a value found in about
2/3 of new diagnoses, meaning a not very aggressive cancer. I had time to
think and learn and make some decisions.
[Aside about Gleason scores]
The Gleason score is a subjective interpretation of how malignant the
prostate cancer cells look under a microscope. The two values are the
nature of the primary population of cancer cells and the nature of the
secondary population of cancer cells. Each score may range from 1 to
5, one being "almost normal" and 5 being "very aggressively malignant".
A score of 3 is about average, and in my two small samples both
primary and secondary populations were 3.
The primary population is the dominant one, after "normal" cells are
discounted. This is the bulk of the non-normal cells on the slide.
There may be a smaller population of non-normal cells, and this is
referred to as the secondary population and determines the second
value in the Gleason score. If there is no such secondary population,
both Gleason values are the same (e.g., 3+3).
The order of the two values in the score are of significance; that is,
4+3 is more aggressive and worrysome than 3+4, for example.
A good reference, with diagrams, is noted in the
Bibliography.

[Note about estimated PSA]
The estimated value in the table of 6.2 at the time of my biopsies in
late July 1999 was a conservative guess. It
assumes the slowest possible growth of my PSA values consistent with
the 1.9 in December 1997 and the 5.4 in April 1999, namely a linear
growth that started exactly in December 1997. Over 16 months, the PSA
score grew by 3.5, so I extrapolated the same growth out another 4
months to August, yielding a value of 6.2 about the time I started
responding to my diagnosis.
If we assume that the PSA growth started later than December 1997, its
linear growth rate would have had to be steeper, and the August 1999
value higher.
Likewise, a more realistic model is based on the fact that cancer cell
growth, once started, is more or less exponential, and so constantly
accelerating. This also yields an even higher estimated value by
August 1999.
[I should point out that "conservative guess" as I used it in the first
sentance of this note was meant as a mathematically conservative
estimate, in the sense of not overestimating my PSA -- what was the
smallest reasonable value it might have been? One might make a
medically conservative guess, where "conservative" means to not
underestimate the severity of the cancer, and this, of course, would be
a somehat larger number, depending on the growth model assumed.]
|
[Notes on the subsequent values]
A prostate biopsy is a violent agitation of the gland and its natural
healing mechanism elevates the PSA level for some considerable time,
whether there is cancer present or not. The general consensus is to wait
2 months after a biopsy for follow on PSA measurements. And so I did.
In the meantime, I began to put a program together and follow it. More
on this below. I should note that all tests except one were done at
Stanford University Hospital, so I had tried to eliminate the variations
due to laboratories. The first PSA, at the end of September 1999 was
1.9 ng/ml, exactly what it was in December 1997 when it was normal.
A couple of weeks later, a local Longs Drugstore offered a low-cost
finger-prick version of the PSA test, which I decided to try. Instead
of drawing blood, sending it to a lab and getting the results back in a
day or two, they used a finger prick to draw a few drops of blood that
were then impressed on some blotter paper. This was sent to a lab in the
mid-west and results mailed back about two weeks later. Not all that much
more convenient, in my book. But their value was 1.4 ng/ml, the lowest on
the chart. Since it was a different lab, it is denoted by an asterisk (*)
in the table above. [The test described is not an off-the-shelf kit;
rather it was done by a lab tech who travelled from store to store,
also doing cholesterol and other screenings.]
Subsequent values, at roughly one month intervals, have fluctuated about
2.2 +/- 0.2 ng/ml (that is plus or minus roughly 10%), as expected if it
were really "constant".
|
[Notes on the values of July 2002]
On 22 July 2002, I had my PSA taken at Stanford Univeristy Hospital, my
usual site, about 9:30 am. It was 2.16 ng/ml, consistent with my
"normal" and with the last couple of readings. About 11:00 am, I was
scheduled for an MRIS at UCSF, and they also drew blood for a PSA.
It was 1.63 ng/ml. The difference is beyond mere fluctuations and, I
suppose, is a cautionary tale about using the same lab consistently.
|
After the initial shock wore off a bit, and I gave myself a week or so
to assimilate the bad news, I decided that I had to educate myself about
the disease and about my options. My understanding, from a conversation with
the Stanford urologist who delivered the news, was that my cancer was
still rather small and not very aggressive. This gave me some time to
learn, some time to collect my thoughts, some time to explore and find
the best practitioners in the Bay Area.
My experience, explorations and evolving program of treatment will be
discussed in greater detail in subsequent sections, but the major
components should be mentioned here:
- Self-education
- Augmenting the vitamins/nutrients and herbs I was already taking
- Modifying my diet
- Exercise
- Finding a physician I could work with
- Seeing alternative practitioners
- Getting two "secret weapons"
- Deciding that the medical approach that made the most sense to me was a
radical prostatectomy, to be done by the physician I had found
- Deciding that aggressive monitoring of the state of my disease was
important
- Deciding that if I could avoid surgery or any other medical treatments
forever or for as long as I could, that would be even better.
My initial approach was to buy and read a few books. I figured that by
doing so, I would have in each a coherent picture of the authors'
knowledge and points of view. This would bootstrap a basic understanding
of the anatomy and physiology of the gland and lay out most of the treatment
options as of the time of their writing, roughly a year or two before
my diagnosis.
These are the books I read in the approximate order that serendipity led me
to them:

I also went on the Web early in this process. Working at a high-tech company,
I had fast web access, so frustration with the slowness of searching from
home over a modem connection was not much of a factor. What was a
consideration for me was the sheer volume of data, from reputable and
solid, through first person accounts, to the somewhat fringe. Not only is
there an enormous quantity to wade through, but, at every stage, one needs to
judge the usefulness and veracity and relevance of what you are reading.
Early on in the process I came across Andy Grove's 1996
Fortune Magazine article
on his experience with prostate cancer. And, for a while, his
choices (high dose seed implants and removal followed by external
beam conformal X-radiation) made a lot of sense to me. His is a very
well written and important story.
I also talked with doctors. I wanted to find the best in the Bay Area. And
since I live only a few miles from Stanford University Medical Center, I
tried them first. I figured that the Bay Area was a world-class center
of research in general and should have some world-class prostate cancer
treatment centers and physicians. I did not want to have to go far from
home, if I could avoid it, for consultation and treatment because of the
additional strain it would put on my wife and myself.
I consulted at first with the Stanford urologist. I knew I did not want him to
be my primary physician in treating my cancer, but he could recommend people.
Naturally, the several top US institutions came up:
Poking a little further, UCSF also started
coming up a lot. (http://ucsf.edu/)
My wife has a cousin who was a urologist in Southern California. We spoke
with her a few times. She was supportive but rather traditional in
her approach: being a surgeon, she believed surgery to be the most
appropriate thing for me to do. But she was still supportive of my desire
to try to avoid both surgery and radiation, if possible. Unfortunately, she
was not familiar with Bay Area practitioners.
I called an old college friend who is now a Professor in the Medical School
at the University of Virginia. When we had spoken about his research a year
or two previous, it seemed as if he were onto something that could be very
clinically useful in addressing all kinds of ailments, including cancer.
Unfortunately, it still seemed 5 to 10 years out. However, he had a
former colleague, an MD/PhD who did post doctoral research with him, who
was now a urologist at the University of Chicago. And he was involved with
surgery as well as other research. He had been trained at UCLA and did a
residency in urology at Stanford, so he was familiar with the players in
the Bay Area. And he was open to the possibilities of alternative treatments.
So I called Professor Mitchell Sokoloff in Chicago and he was gracious
enough to spend a lot of time on the phone with me, and then kept up an
email correspondence. He also recommended Professor Peter Carroll, chairman
of the urology deparment at UCSF as a world class surgeon and good person. I
felt good getting an independent, knowledgeable person with no axe to grind
or self-interest to promote as a foil to my ideas and discoveries.
I spoke with Steven Hancock, MD, at the Stanford Radiological Oncology
facility. We spoke of the different forms of radiation, of what they did
there, and of survival rates, long term and short term, as well as the
side effects of the treatment. When he finally showed
up, an hour and a half late for our appointment, he was willing to spend
as much time with us as we needed as well as to provide reprints of research
he had been involved with on long-term survival rates.
I spoke with Dr. Gill, the Stanford urology surgeon who inherited Dr.
Freiha's mantle as the most skillful surgeon there. But he was a rather closed
individual, unwilling to even look at some research we had brought for his
consideration. He may have been a skilled mechanic, but I wanted to be
treated as a person rather than as a slab of meat.
I spoke with Professor Peter Carroll at UCSF, first a long telephone
conversation and then in person. He is not only an expert on the nerve
sparing forms of radical prostatecomy, but is involved in various kinds
of research on prostate cancer, including some studies with colleagues on
dietary approaches, including Dr. Dean Ornish's program at the
Preventive Medicine Research Institute
in Sausalito, Calif. He was very open to
following along with my program, although he also felt that, at best,
I'd only be postponing the inevitable. My wife and I felt that we could
work with him as a partner, whether I opted for surgery in the end, or
if I could avoid it forever.
We talked with prostate cancer survivors, learned their stories, their
lessons, their contacts. This includes my friend who is into 7 years post-op
(as of Autumn 2000) and doing quite well. I also started attending
the monthly meetings of a local prostate cancer support group where I
could learn from others' experiences as well as help educate people
about what I found or knew. This paper is based on a short talk I gave
my third month there.
This is the medical option we initially decided to pursue, if we had to
pursue any medical option. Our reasoning was this. First off, by the
medical criteria, I was a prime candidate for surgery: I am young,
healthy, not overweight, with a small, early stage tumor. This means
I'd be easy to operate on, would likely recover quickly from the surgery,
and it would be very probable that the entire cancer would be removed in
the procedure.
Side effects of incontinence and impotence, however, are significant, even
with the best of nerve sparing surgeries and surgeons. (A recent study
[Siegel, et al., Journal of Urology, vol 165, no 2, pp 430-435
(Feb 2001)] found that "Erectile dysfunction develops in greater than 80%
of the patients treated for prostate cancer" whether by surgery or
external beam radiation.)
Radiation therapies (seed implants of various types, external beam Xrays
or proton beams) as well as cryotherapies are less invasive, but also
lead to similar complications and side effects. They come on a bit more
gradually, but in the end roughly 30-50% of men who have undergone either
approach are impotent (depending on whose statistics you read) and 10%
have some form of incontinence, whether mild and annoying or severe and
limiting.
The downside of radiation is the long-term survival statistics relative to
surgery. Both are comparable out to about 10 years for "best practice".
(Reference)
After that, folks who have had radiation do not, on the average, survive
as long or have as a high a percentage who remain prostate cancer free.
This may not be as great a consideration to, say, an 80 year old with
heart problems, but to me, with my intent to live another 40 or more
years, it is an important consideration.
Another consideration is that surgeons do not like to operate on someone
who has had radiation, if their prostate cancer recurs. This is because
the radiation has toughened the tissue of and surrounding the prostate,
which makes the surgery a little more difficult. Such "salvage surgery",
however, is done by some surgeons.
In the end, physical removal of the organ and the cancer seemed like it
would be more effective than trying to kill the cancer cells via some
other modality. With improved surgical and post-operative techniques,
I had hoped that the negative consequences of the procedure could be
minimized, if not eliminated. And having found Dr. Peter Carroll gave me
some assurances that I had found a master craftsman with a lot of experience
and who I could work with, if or when I chose that route.
The question to be addressed here is, How do you know whether your approach
is working or not, whether the cancer is disappearing, being held in check,
or growing and merits a more radical approach?
The answer is, figure out what techniques and technologies allow one to
"see" what is happening with the cancer and sample often enough to follow
its course and fluctuations. And do so with a greater frequency than the
physicians might recommend. Again, you must be your own best advocate.
There are a number of approaches. The first and most obvious is following
my PSA levels. These I have taken roughly every month (versus the every 3
months that was suggested by my urologist). PSA, as discussed elsewhere here,
is a proxy for the growth of cancer, in general. But not always. In some
men, prostate cancer abounds with a low PSA level. In others, elevated PSA
is a result of non-malignant causes. I suspect both these situations do not
occur too often, but with a high enough frequency to have been noted. My PSA
rise seems to have been an appropriate tip-off that something was awry.
Another consideration with PSA is that herbs such as saw palmetto, one of the
things I started taking, tend to lower the levels. This is probably a good
thing. But is it just masking the cancer or is it really fighting it? I
haven't heard any answers to that question.
So, this is one easy step in following how things are going. By and large,
since I started my program and PSA monitoring, it has been 2.0 ng/ml +/- 10%,
the fluctuation range I was told to expect and within the "normal" reading
I had pre-cancer.
It should be noted that as a man ages, his prostate gland starts growing. So
a larger normal gland, putting out a roughly constant amount of PSA protein
per unit volume, will, over the years result in higher PSA values overall.
That is why the "normal" ranges are larger as men get older. The rise in my PSA
with the years, especially after mid-2008 (9 years after diagnosis), is consistent
with this and not alarming.
The DRE is a traditional way to find cancers that have grown to palpable
size on the back wall of the prostate. But it is useless in detecting small
cancers such as mine until they are quite a bit more advanced. Since I want
to prevent mine from getting to that stage, the DRE would be a null test,
basically a waste of time.
Likewise, a Trans-Rectal UltraSound, while able to image more of the prostate,
is also a rather crude imaging tool. Its resolution is poor and its sensistivity
to growths in the gland is also not very good. It is better than the DRE for
detecting physical abnormalities, but again, it is incapable of detecting
cancers as small as mine. So, this, too, does not seem like a useful avenue
to pursue.
This is a technique pioneered at the University of California, San Francisco
by Professor John Kurhanewicz and his colleagues, and recently (winter 2000?)
begun on an experimental basis at Memorial
Sloan-Kettering in New York City. It combines magnetic resonance imaging of
the pelvic region with a superimposition of spectroscopic data that are very
sensitive to prostate cancer cell metabolism. A coil is inserted in the rectum
and a pickup is placed on the abdomen while one is in a strong field magnetic
resonance imaging device. The closeness of the probe to the region being
imaged allows the resolution of the MRI images to be 0.5mm x 0.5mm pixels,
with slices about 3mm apart. The software transforms the geometries to be
faithful representations in two dimensions, unlike the ultrasound images.
The spectroscopic part is done simultaneously. Here the returned radiofrequency
radiation is analyzed and the energy in various frequency bands calculated.
There are particular regions indicative of the amount of activity in the
citrate cycle (one path of cellular energy utilization), of choline metabolism,
creatine levels, and of some other distinct cellular metabolic processes.
Combined, these are very sensitive to the nature of the cells in the voxel
(volume element) being sampled. The sampling can distinguish among
- normal prostate cells
- malignant prostate cells
- cells involved in BPH
- prostatitis
- populations of necrotic (dead or dying) cells (say, as a result of
previous radiation treatments or brachytherapy)
The sensitivity is very high although the spatial resolution is much lower
than the MRI imaging itself. The spectroscopic voxels are approximately
1/4 cc, which translates to cubic volumes of 6.25 mm on each side.
The coarser resolution is due to the need to subtract out the higher (dominant)
water background to be able to discern the other, weaker, peaks.
With the 3 Tesla machine, under development since 2003 (and still in test as
of Aug 2004), the spatial and volumetric resolution is much better: voxels
are now 0.16 cc, translating to a cube with sides roughly 5.5 mm.
September 1999 Imaging
I had my first MRIS done on 1 September 1999, roughly 6 weeks after my second
set of biopsies. Biopsies are violent attacks on the gland and cause some
amount of internal bleeding where the samples are taken. Blood accumulates
in and near the prostate and it may take a couple of months for it to fully
dissipate. And this blood confounds the imaging, making it more difficult
to interpret whether there is some abnormality in the gland or whether what
is being seen is merely an artifact. Such was the case on my first imaging.
The imaging did confirm the presence of cancer, more on the right side (where
the biopsies discovered it), with scattered evidence of possible cancer in the
left side. It showed no penetration of the capsule (a thin membrane enclosing
the prostate gland) or external evidence of cancer in lymph nodes, seminal
vesicles, or bones. There was a question about whether some of what the
images showed was cancer near the capsule (edge of the gland) or just blood.
April 2000 Imaging
My second MRIS was done on 3 April 2000, 7 months after the first. All
bleeding-related artifacts were gone, although the cancer was still there.
It was confined near the mid-line, a bit more on the right than left. It
was difficult to compare the true extent with September's images due to the
confounding effects of the earlier bleeding. Overall, there were no
abnormalities noted in the high resolution images. At that resolution,
my gland was both small and healthy looking.
November 2000 Imaging
My third MRIS was done on 3 November 2000, another 7 month interval.
The state of my gland was essentially unchanged from April's imaging.
The gland was small (34 cc) and healthy looking in the imaging part,
with some color differences from "normal" from the midgland to the
apex [bottom] near the midline; most of this was not supported by the
spectroscopic component of the imaging. However, there was a small
amount of malignant tissue metabolism still detected at the apex near the
midline, unchanged from April.
And, there is no sign of any disease outside the prostate nor at the
capsule (the boundary of the gland).
April 2001 Imaging
My fourth MRIS was done on 19 April 2001, 2 weeks after a PSA reading of 2.6.
The imaging showed a gland of 39 cc (and a PSA density of 0.06). It showed
some enlargement of the central gland, consistent with BPH, and some evidence
of prostatitis, even though I was symptom-free. The gland was about 5 cc
larger than 5 months previous.
There was one voxel of borderline cancer metabolism. In previous images,
there were several voxels of borderline metabolism, all within the right
mid gland. "The spectroscopic abnormalities are much less evident on the
present study." And later, "The spectroscopic findings are much less
apparent on the present scan, suggestive of positive treatment response."
And again, there was no sign of any disease outside the prostate nor at the
capsule (the boundary of the gland). All good news, indeed.
January 2002 Imaging
My fifth MRIS was done on 9 January 2002, a few hours after a PSA reading of
8.64. (On 11 Jan, PSA was 6.70; on 15 Jan it was 5.43; on 21 Jan it was 5.45.)
This imaging showed a number of voxels in the right midgland with abnormality,
changes in all 3 markers (decreased citrate, elevated choline, ...[?]
polyamines). Prostate volume was 33 cc (smaller than previous images).
The radiologist's report states "The focus at the right base is more apparent
as compared with the prior examination....MR spectroscopy demonstrates
interval development of a small focus of tumor metabolism at the right base."
Further discussions, informed by my experience with asymptomatic prostatitis
in May 2001, led to my being told that an acute infection could lead to
these signals. [Most men with prostatitis have chronic infections,
which present differently in the MRIS. The primary researcher said he
had seen acute prostatitis only 2 or 3 times out of the several thousand
images he had looked over in his career. However, he declined the opportunity
to reimage me immediately after my course of antibiotics, foregoing the
possibility of developing a before and after to allow better
discrimination between acute prostatitis and cancer.] In order to rule that
out, or to deal with it, I started on a 2 week course of Cipro, a powerful
antibiotic, on 23 January 2002, followed by a second 2-week course. As one
can see from the graph and table in the beginning of this paper, my PSA
came down to around 2.4 after 3 weeks, stayed there for a couple of months,
and then returned to my "normal" levels of about 2.0 ng/ml. I conclude
from this that the anomolous readings in this set were another episode of
asymptomatic prostatitis.
July & September 2002 Imaging
My sixth MRIS was done on 22 July 2002. About an hour and a half before the
test, I had blood drawn at Stanford Hospital; the PSA was 2.16 ng/ml. I
also had blood drawn at UCSF; the PSA was 1.63 ng/ml. Go figure.
There was no evidence of any metabolic abnormality in the Spectroscopic
analysis. That is, no evidence of any cancer. The radiologist concluded
that all abnormalities seen in the previous image of 9 Jan 2002 were due
to prostatitis rather than cancer, and that all had resolved themselves in
the interval. The gland measured 36 cc; using the Stanford PSA of 2.16 ng/ml,
my PSA density was 0.060 ng/ml/cc.
My previous images will hopefully be of some help in allowing the
research team to come up with a scheme for differentiating prostatitis
from cancer. Since they have few unambiguous images of acute infection,
all the data they can get will help.
This finding does not necessarily mean all my cancer is eradicated. Rather,
it has regressed to the point that this imaging technique is unable to
see it amidst the surrounding healthy tissue. As a consequence, I do not
plan of changing my regimen.
On 9 September 2002 I had a color doppler TRUS by Dr. Katsuto Shinohara at
UCSF. Absolutely no abnormalities or suspect areas were seen. Dr.
Shinohara said that "power doppler ultrasounds" that I had heard of were
exactly the same as what he was using. It was a relief to have both
imaging modalities confirm that any remnant cancer is too small and
inactive to be picked up by these techniques. Prostate size was estimated
to be about 40 cc; using the previous PSA of 2.08 ng/ml, my PSA
density was 0.052 ng/ml/cc. He also noted "about 14 cc of transient
hypoplasia", something I need to have clarified.
June 2003 Imaging
My seventh and eighth MRSIs were done on 16 June 2003. The first was a standard
exam, done at UCSF on their 1.5 Tesla GE machine. The second was done that same
afternoon at a 3 Tesla GE machine installed at SRI in Menlo Park, CA. The
latter's magnetic field strength is twice that at UCSF, and so allows for higher
resolution images, better spectroscopy and/or faster acquisition times. It
is being calibrated and I volunteered for a side-by-side comparison study
as the scientists and operators try to arrive at the best settings for the
highest quality imaging.
The MRI images both showed no abnormalities. In the right midgland region,
the images were a little darker than normal, but nothing notable. (Recall
that previous imaging and the biopsies indicated cancer metabolism in the
left midgland, where there is now no evidence of cancer.) The gland volume
was estimated to be 38.0 cc; using the PSA value of 2.18 ng/ml, the
PSA density was 0.057 ng/ml/cc.
Spectroscopically, in both images, in the right base to midgland, there was
an alteration in the expected normal metabolism. Here, however, there was
no elevation of the choline signal, there was a loss of some SNR [signal to
noise ratio], and there was a loss of citrate levels. These are less a sign
of cancer than a possible signal of chronic prostatitis, especially
considering how these signatures come and go from image to image over the years.
I had another power doppler TRUS on 04 August 2003 with Dr.
Shinohara at UCSF for an independent corroboration of the MRSI results.
Again, no signs of cancer were apparent. The gland had grown some (see
table below), but showed no signs of malignancy. The left midgland
showed a persistant hypervascularity (increase above normal of amount
of blood vessels). This is the same area that the June 2003 MRSIs
showed signs of lingering possible prostatitis. Recall that the positive
biopsies were originally in the right midgland, far from this region.
On 07 June 2004, I had my next power doppler TRUS with Dr. Shinohara at
UCSF. The prostate volume was about 48 cc; the year before it was about
46 cc by TRUS. This was essentially the same size. Dr. Shinohara stated
that the MRSI underestimates the size by about 20% relative to the TRUS.
[The corresponding MRSI volume would thus be about 37 cc.]
He also saw a small protrusion of the prostate into the bladder on one
side, indicative of mild BPH. There were a couple of small areas
of hypervascularization [that is, increased blood flow], one on each side,
but he did not feel that they were large enough or strong enough to be of
concern. And he mildly suggested another biopsy, which I resisted and we
discussed.
August 2004 Imaging
My ninth and tenth MRSI images were done on 5 August 2004. In the morning, I
was imaged in the new 3 Tesla GE machine at UCSF's new China Basin facility
in San Francisco. In the afternoon, the same protocols were used at their
standard 1.5 Tesla machine at their original facility. As in the previous
year, a side-by-side comparison allows both validation and improvement to the
settings used in running the machine as well as in the software used for
post-run analysis.
The 3 Tesla images provided a much higher spatial resolution than the
1.5 T images, and both sets were in concordance. The news again was good -
no signs of cancer, no changes from the previous imaging, to the limits
of the technique's resolution. Recall that my biopsy found some small
amounts of cancer in the right midgland in July 1999. None of that
has appeared in the images for quite some time, so is not growing, if
still present at all.
Again, the radiologist noted "a small focus of decreased T2 signal within
the right midgland with equivalent signal on MR spectroscopy." In this
region of the gland there is a mix of stromal cells and glandular cells.
The glandular cells create the prostatic fluid which flows down the local
ducts, eventually accumulating in the seminal vesicles and the ejaculate.
This fluid has lots of free water. The T2 imaging measures the morphology or
anatomy by looking at water. Lots of free water implies a very long T2 relaxation
time.
In prostate cancer, the glandular cells are the ones that become malignant,
in general, and the ducts get filled with cancerous growth. This leads to
less water being present and a darkening in the T2 weighted image. However,
other things can cause this as well, and so spectroscopy is used to try to
differentiate what is going on. In my case, this same area has "equivocal
metabolism", the same as in previous images, though different from when I
was imaged during a bout of prostatitis. So there is no obvious cancer
signal and no changes over several years, all good news. Only a biopsy of that
region could serve to differentiate histologically what is really going on
there, but for me there is currently no incentive to do so -- the potential
gain of knowledge would not inform any decision to do anything. If any
cancer is still invisible to MRSI and TRUS and my PSA levels are relatively
static, I should just keep on doing what I'm doing.
March 2006 Imaging
My eleventh MRSI was done in the 3 Tesla GE machine at UCSF's China Basin
facility on 6 March 2006. Because of the prostatitis that seemed to be
running in my system from December 2004 through around August of 2005,
we decided to wait until my PSA returned to its "normal" levels and
stabilized there before doing another set of images. This is because
prostititis often looks like cancer in the spectroscopic images and
we did not want to confound the interpretation process.
I received a CD-ROM of the non-spectroscopic images, along with
WindowsXP software for looking at them, when I left the imaging
session, and a more complete CD-ROM with all my images from all MRSIs
by mail a week or so later. The CD-ROM now includes a Windows-based
image viewing program, with an on disk manual for how to use the
software. Still, interpreting the images is another issue altogether,
and guidance should be provided there, too. The CD-ROM should also
include the spectroscopic images, which take additional processing, but
are now also available to the subject.
The radiologist report took about a week to be drafted. It contained very
little information -- seemingly, less and less each time -- but the bottom
line is that there have been essentially no changes since my previous
images, in fact, almost no changes for several years. This is good, as
there are also no signs of cancer. On the side opposite where my biopsy
found a little cancer, there are some changes again, likely due to
inflammation. ("A small band-like area of decreased T2 signal is seen in
the left mid gland, which extends towards the apex. This may represent
prostatitis.")
The rise in my PSA (at Stanford) to 3.27 ng/ml on the day of the exam
is of concern. It may be the beginnings of another round of asymptomatic
prostatitis. I doubt that it is an artifact of a URI (upper respiratory
infection, a cold) I was just getting over at the time.
March 2007 Imaging
On 5 March 2007 I had my twelth MRSI using the 3 Tesla machine at UCSF's China
Basin facility. The new aspect to this imaging session was the use of a
Gadolinium contrast agent for the last set of images. Gadolinium is a
common contrast agent used in MRIs and is administered intravenously. It
makes cancerous tissue easier to see. This was also to be a baseline imaging
session before I started taking Peenuts as a supplement to try to reduce or
eliminate my background chronic (asymptomatic) prostatitis inflammation.
The results were the best yet. Essentially, there were still no signs of cancer,
a small region of ambiguous signal previously seen in my images was even
smaller and more difficult to discern. There were no detectable metabolic
abnormalities.
February 2008 Imaging
On 29 February 2008 I had my thirteenth MRSI using the 3 Tesla machine at
UCSF's China Basin facility, this time with no contrast agent. I reviewed
preliminary images with a radiologist after the imaging session. (The
spectroscopic images require additional processing and take an extra three
days or so to be developed, according to him.) Everything looked "normal",
with no significant changes from previous images (which are also available on
their computer system for comparisons).
The written radiology report also noted that the "[p]reviously described
focal area of low T2 signal within the right midgland is no longer seen in
the current study... MR spectroscopy demonstrates no definite abnormality....
No definite MR or MRS evidence of tumor."
The biopsy I had in 1999 found tumor in the left midgland, which never showed
up in the MRSI imaging I have had. However, there have been low level
ambiguous signals in the right midgland in all images up until the
February 2008 imaging. I take this to indicate some improvement in an
undefined irregularity there.
After the imaging, I also was interviewed by a Product Manager from MedRad,
a company that makes the transrectal probe used in the MRSI procedure. The
videotape is to be used in educational videos on the process and technology
from a patient's point of view.
March 2009 Imaging
On 31 March 2009 I had my fourteenth MRSI using the 3 Tesla machine at the
new UCSF Mission Bay campus, at Byers Hall, also with no contrast agent.
A new rigid endorectal probe was used as part of the qualification of the
technology. In particular, in addition to looking at signals from hydrogen
(mostly in water), it also was looking at signals from Carbon-13.
Again, the radiologist's report stated: "MR imaging and MR spectroscopy
demonstrate no convincing evidence of tumor. There is no extracapsular
extension or seminal vesicle invasion. No lymphadenopathy is seen in the
pelvis.... No suspicious osseous lesions identified."
March 2010 Imaging
On 16 March 2010 I had my fifteenth MRSI using the 3 Tesla machine at the
new UCSF Mission Bay campus, at Byers Hall, also with no contrast agent.
A new rigid endorectal probe was used again as part of the qualification of the
technology. In particular, in addition to looking at signals from hydrogen
(mostly in water), it also was looking at signals from Carbon-13.
Again, the radiologist's report stated: "...no clear cut tumor metabolism
is observed. No extracapsular extension, no seminal vesicle invasion, no
lymphadenopathy, no suspicious bone lesions.... Compared to the study from
03/2009, no significant change. No tumor focus in either MR or MR
spectroscopy."
March 2011 Imaging
On 28 March 2011 I had my sixteenth MRSI using the 3 Tesla machine at the UCSF
China Basin facility. Again, no contrast agent was used. My reported prostate
size was much larger than the previous year (67 cc versus 47.4), and will be
recalculated. (See the note below.)
Signs of BPH were clear, both spectroscopically and morphologically (the shapes
of elements in the regular imaging). Again, there was the "equivocal metabolism"
in the right base to mid-gland. This is not a sign of cancer, but not normal
cells either. For the most part, it has been present in my images from the
beginning, growing and shrinking. It is likely a sign of an underlying
inflammation or infection that never quite goes away. There were no significant
changes from the last year's MRSI, which is a consistent motif in the
radiologist reports over the years.
April 2012 Imaging
On 4 April 2012 I had my seventeenth MRSI using the 3 Tesla machine at the UCSF
China Basin facility. Again, no contrast agent was used. My reported prostate
size was larger than in previous years, and I am sure a recalculation would
reduce this size somewhat.
Again, "extensive changes related to benign prostatic hypertrophy with
associated nodules" were noted. These nodules were "unchanged compared to
prior exams, and [do] not demonstrate any other diffusion or spectroscopic
abnormality." And, "No change compared to prior exams."
March 2013 Imaging
On 20 March 2013 I had my eighteenth MRSI using the 3 Tesla machine at the UCSF
China Basin facility. This time, a gadolinium contrast agent was used for the
final set of images, after the spectroscopy.
Again, there were no signs of cancer (or prostatitis), but the radiologist noted
"extensive changes related to benign prosthetic hypertrophy [BPH], with
associated nodules." As can be seen from the table below, my gland continues
to grow.
April 2014 Imaging
On 21 April 2014 I had my nineteenth MRSI using the 3 Tesla machine at the UCSF
China Basin facility. This time, a gadolinium contrast agent was used for the
final set of images, after the spectroscopy.
The radiology report noted that my gland continued to grow and that "the central
gland (transitional zone) [signal intensity] is related to benign prostatic
hyperplasia" or BPH. In addition, there was no evidence of extension beyond the
prostate gland, seminal vesical, lymph node or bone involvement.
While there is "no clear abnormal spectroscopy" in the right apex region, a
"decreased T2 signal" may be "suspicious for focus of prostate cancer". Again,
an ambiguous signal, which may also be an artifact of the prostatitis I had
from September to Decemeber of 2013.
In the subsequent imaging, April 2015, this signal from the right apex was
absent, an indication that this was inflammation and not cancer.
April 2015 Imaging
On 23 April 2015 I had my twentieth MRSI using the 3 Tesla machine at UCSF's new
Bakar Cancer Center in Mission Bay, San Francisco. Gadolinium contrast was again
used for the final images in the sequence.
The radiology report discussed a 13 mm focal lesion in the left posterolateral
peripheral zone and the midgland/apex, which had not been seen in previous images.
On review of the 2014 images, a tiny amount of signal was seen in the diffusion
images in this region, but it was unremarkable at the time (i.e., not significant
enough to make remarks about). Four of the seven parameters that current imaging
technology provides are consistent with cancer -- or inflammation. It is still
difficult to differentiate prostatitis from cancer on the images. If cancer,
the imaging is consistent with Gleason 3, a slow growing cancer. It was suggested
that I continue active surveillance and wait another year for my next imaging.
The change in prostate volume, from 56 cc in 2014 to 75 cc in 2015 is also
suspicious. The folks in radiology reexamined the images to derive better
volume estimates for both years, which impact the PSA density calculations. Given
the current numbers (PSA 8.1 in Feb 2015, volume of 75 cc), my PSA density is
0.108, well within the "safe" range of <0.15.
Note: because the jump in volume as measured by the radiologist from year to year
was unreasonably large (56 cc to 75 cc), I asked the researchers to recalculate
the 2014 and 2015 volumes more accurately. The 2014 volume was changed to 56.3 cc.
The 2015 volume was changed to 60.72 cc. This leads to a PSA density in 2015 of
8.1/60.72 = 0.133.
June 2016 Imaging
On 03 June 2016 I had my twenty-first MRSI using the 3 Tesla machine at UCSF's new
Bakar Cancer Center in Mission Bay, San Francisco. Gadolinium contrast was again
used for the final images in the sequence.
The radiologist's report noted that the central gland is consistent with benign
prostatic hyperplasia (BPH). It also noted again a lesion in the left anterior
peripheral zone (1.1 cm x 0.57 cm x 0.8 cm) with a well defined focus of low signal
intensity on T2-weighted imaging, marked restricted diffusion and suspicious
enhancement (DCE positive). However, on spectroscopy, no suspicious metabolism is
seen in the lesion.
On consultation with the researchers, the suspicious area from 2 years ago had
vanished (the left peripheral zone), and the new one (left apex peripheral zone)
appears with 4 weak signals, but no spectroscopic signal. This can be prostatitis
and seems not something to worry about since PSA is steady and PSA density
remains steady and within the safe range as well.
The radiology report stated the gland volume was 78.1 cc; on request for a remeasure
from the images, a radiologist came up with 82.4 cc and a researcher who had
recalculated my PSA volume in the past came up with 73.9 cc. All of these, of
course, are estimates.
June 2017 Imaging
On 9 June 2017 I had my twenty-second MRSI using the 3 Tesla machine at UCSF's
Bakar Cancer Center in Mission Bay, San Francisco. Gadolinium contrast was again
used for the final images in the sequence.
Again, the radiologist's report noted that the central gland is consistent with
benign prostatic hyperplasia (BPH). The 1.1 cm lesion seen last year in the left
peripheral zone could not be seen at all this time in either T1, T2 or diffusion
weighted imaging.
No suspicious metabolism (indicative of cancer) could be seen anywhere. There
were no signs of extension outside the prostate capsule, into lymph nodes,
seminal vesicles or bones.
The PI-RADS score was assigned a value of 3, indicating that something is
suspicious but cannot be classified as cancer. This is consistent with low
grade asymptomatic prostatitis which can look like prostate cancer in these
images. The fact that lesions come and go and that my PSA density is
consistently arount 0.10 enhances this interpretation.
The prostate volume estimated was 91.2 cc. This year I did not have a more accurate
recalculation done.
June 2018 Imaging
On 12 June 2018 I had my twenty-third MRSI using the 3 Tesla machine at
UCSF's China Basin facility in San Francisco. Gadolinium contrast was again
used for the final image in the sequence.
The prostate volume was estimated to be 100.6 cc. With my most recent PSA of
7.68, that leads to a PSA density of 0.07 ng/ml/cc, indicating no cancer is
present.
To quote the report:
Heterogeneous appearance of the central gland is consistent with
benign prostatic hyperplasia.
No suspicious lesions identified on MRI.
Capsular margin and neurovascular bundle: No evidence of
macroscopic extracapsular extention.
Seminal vesicles: No evidence of seminal vesical invasion.
Lymph nodes: No lymphadenopathy in the field of view.
Bones: No suspicious lesions in the field of view.
...
IMPRESSION:
-PI-RADS v2 score 2: clinically significant cancer is unlikely
to be present.
-The lesion identified previously is even less conspicuous and
may have represented sequelae of prostatitis.
June 2019 Imaging
On 20 June 2019 I had my twenty-fourth MRSI using the 3 Tesla machine at
UCSF's Mission Bay facility in San Francisco. Gadolinium contrast was again
used for the final image in the sequence. This was the first image where an
endorectal probe was not used. Rather, I lay on top of a probe plane and had
another placed over my abdomen. (This later was the same as in all prevous
images.) The technician explained that new hardware and software allowed
faster and sharper images to be taken without needing to use the endorectal
pickup device. In fact, the imaging session took about 40 minutes as
opposed to previous ones which took an hour to an hour and twenty minutes,
depending on which images were being taken.
The prostate volume was estimated to be 100 cc. With my most recent PSA of
9.0, that leads to a PSA density of 0.09 ng/ml/cc, indicating no cancer is
present.
To quote the report:
Heterogeneous appearance of the central gland is consistent with
benign prostatic hyperplasia.
Capsular margin and neurovascular bundle: No evidence of
macroscopic extracapsular extension.
Seminal vesicles: No evidence of seminal vesical invasion.
Lymph nodes: 8 mm left pelvic sidewall node...
Bones: No suspicious lesions in the field of view.
...
IMPRESSION:
-PI-RADS v2 score 2: clinically significant cancer is unlikely
to be present.
No evidence of macroscopic extracapsular extension. No evidence
of seminal vesicle invasion.
Nonspecific 8 mm left pelvic sidewall lymph node. No
suspicious bone lesions.
No change from 2018.
July 2020 Imaging
On 7 July 2020 I had my twenty-fifth MRSI using a 3 Tesla machine at UCSF's
China Basin facility in San Francisco. This is a strictly radiology facility,
so there was minimal liklihood of exposure to Covid-19. There were also
few people at the facility, unlike in years past.
Again, there was no endorectal probe and the imaging session took only
about 40 minutes. Aside from the prostate having grown slightly from last year
(from 100 to 107.5 cc), consistent with its trend over the years (see the
table below), results were essentially unchanged from those quoted from
the 2019 report, above. Again, "No significant changes seen since the prior
MRI."
July 2021 Imaging
On 08 July 2021 I had my twenty-sixth MRSI using a 3 Tesla machine at UCSF's
China Basin facility in San Francisco, including, as usual, one set of images
taken with Gadolinium contrast. There were still Covid precautions (mostly
masking of staff and visitors) in effect.
Again, there was no endorectal probe and the imaging session took only
about 40 minutes. Aside from the prostate having grown slightly from last year
(from 107.5 to 115 cc), consistent with its trend over the years (see the
table below), results were essentially unchanged from those quoted from
the 2020 report (and previous reports), above. Again, "No significant changes
seen since the prior MRI." And, "PI-RADS v2.1 score 2: clinically significant
cancer is unlikely to be present."
August 2022 Imaging
On 07 August 2022 I had my twenty-seventh MRSI using a 3 Tesla machine at
UCSF's Mission Bay campus in San Francisco, including, as usual, one set of images
taken with Gadolinium contrast. There were still Covid precautions (mostly
masking of staff and visitors) in effect.
Again, there was no endorectal probe and the imaging session took only
about 40 minutes. Aside from the prostate having grown slightly from last year
(from 115 to 117 cc), consistent with its trend over the years (see the
table below), results were essentially unchanged from those quoted from
the 2020 report (and previous reports), above. Again, "No significant changes
seen since the prior MRI." And, "PI-RADS v2.1 score 2: clinically significant
cancer is unlikely to be present."
September 2023 Imaging
On 14 September 2023 I had my twenty-eigth MRSI using a 3 Tesla machine at
UCSF's China Basin facility in San Francisco, including, as usual,
one set of images taken with Gadolinium contrast.
Again, there was no endorectal probe and the imaging session took only
about 40 minutes. Aside from the prostate having grown slightly from last year
(from 117 to 118 cc), consistent with its trend over the years (see the
table below), results were essentially unchanged from those quoted from
the 2020 report (and previous reports), above. Again, "No significant changes
seen since the prior MRI." And, "PI-RADS v2.1 score 2: clinically significant
cancer is unlikely to be present."
September 2024 Imaging
On 17 September 2023 I had my twenty-ninth MRSI using a 3 Tesla machine at
UCSF's China Basin facility in San Francisco, including, as usual,
one set of images taken with Gadolinium contrast.
Again, there was no endorectal probe and the imaging session took only
about 30 minutes (a new and slightly faster machine). Aside from the prostate
having grown a bit from last year (from 118 to 133 cc), consistent with its
trend over the years (see the table below), results were essentially unchanged
from those quoted from the 2020 report (and previous reports), above. Again,
"No significant changes seen since the prior MRI." And, "PI-RADS v2.1
score 2: clinically significant cancer is unlikely to be present."
The next imaging, probably to be done around September 2025, should again be easy
to compare with the current images and a progress/regress of the cancer
should be discernible.

[Notes on Prostate Volume and PSA Density]
On 7 September 2004, I received a phone call from one of the UCSF researchers.
I was concerned about the apparent growth in size of my prostate over the
previous five years and had discussed this issue with Professor John
Kurhanewicz at UCSF. His team had reanalyzed my images from 1999 to the
present and found, with a more detailed and precise analysis, that my
gland volume was essentially unchanged, approximately 36 +/- 3 cc. In
general, the radiologists apply a simple curve fitting algorithm to estimate
the gland volume, and there are approximations and room for error in the
process. This recalculation also has implications for estimated PSA density;
the numbers in the table above have not been corrected for the "constant"
gland volume.
In 2011 I again had my prostate volume recalculated by a more accurate
technique. The 2010 original value of 47.4 cc was adjusted to 41.5, and the
original 2011 value of 67.0 cc was adjusted to 39.9 cc. These are significant
differences. I am sure the 2012 value of 50.4 would also be adjusted downward
if more accurate techniques were used. But these take a little more human
effort to perform.
In any event, the growth of my gland would explain the gradual rise in
background PSA -- there is more healthy tissue (or BPH tissue) to generate
PSA.
[Note added 3 April 2013 after a conversation with Nanette Perez, RN at UCSF
Urologic Oncology Dept.] PSA density has come to be considered a more important
indicator of prostate health in recent years. Any value less than 0.15 is
indicative of a healthy prostate, one not excreting more PSA per unit volume
than expected. Higher values may be indicative of cancer or of prostatitis.
This calculation is obviously sensitive to the proper calculation of PSA volume.
Consulting the above table, all my PSA density values have been "good" ones so
far.

UCSF Protocol
The UCSF protocol for aggressive monitoring or Active Surveillance (as I
remember it) is
- PSA every 3 months
- free PSA every 6 months
- TRUS every year (power doppler color TRUS)
- MRSI every year
- biopsy every two years
This involves a number of ways of tracking the existence and growth/regression
of the cancer, using blood markers and physical imaging, as well as grabbing
cell samples for histology. Each modality serves to corroborate the others,
while providing somewhat independent means to avoid measurement errors or
blind spots in any one method. Except for the repeat biopsies (as noted above),
this seems reasonable to me. It may be contrasted with the
PRIAS
(Prostate cancer Research International: Active Surveillance) Project,
a European approach using only PSA and biopsies.
The important point in this is not to remain passive and ignorant, but to
keep track of how well life style and other changes are keeping the cancer
in check, to buy time for better medical approaches to emerge, and to avoid,
as long as possible, the side effects of any medical treatments, noting
that many prostate cancers are overtreated and may likely remain indolent
for the rest of your life.
The concept behind what I put together was to engage and enhance my
immune system's response to the cancer by as wide a variety of methods as
I could. The general approach is discussed in Dr. Andrew Weil's book,
Spontaneous Healing, which I came across
a couple of months into this process.
The basic idea is that cells are constantly undergoing division in the body.
Statistically, it is likely that some small fraction of these divisions
are incorrect, producing malignant cells. This can be due to a variety of
factors, including
- random events
- radiation damage (just due to natural background radiation)
- exposure to toxic chemicals (which are more and more around us, in our
food, air, water, and environment in general)
- age-related cellular issues
- inflammation
- etc.
Many of these mutant cells are not viable and die. Many have benign or
irrelevant changes. But some fraction become malignant, depending on the
accumulated mutations in the cellular DNA.
In general, the immune system is capable of finding and killing all these
cells since cancer is a rather rare disease compared to all the cell
divisions that occur in a body over its lifetime. What I was seeking to do
was augment and increase the functioning of my cellular immune system,
since my malignant load was higher than the "normal" background and
additional help was needed. But, if I could succeed at that, I could, at
best, eradicate the cancer; at the middle, keep it at bay and treat it like
a chronic, non-life threatening disease; and at worst,
buy some time for medical techniques and options to improve, as they
have been rapidly over the past few years.
The first pillar of my program is the use of vitamins and supplements.
Over the course of the years I had gradually increased the variety and
quantity of what I had taken, even though I am a firm believer of getting
as much proper nutrition as you can from good, fresh, wholesome food.
As a background, this is what I had been taking for years:
- 6 gm vitamin C per day (3 in am, 3 in pm)
- 400 units vitamin E per day (am)
- 16000 units vitamin A per day (am)
- 120 mg gingko biloba per day (60 mg in am, 60 mg in pm)
- "B-100" pill (am)
- Calcium-Magnesium-Zinc tablet (am)
- aspirin (1 in am)
Vitamins C and E are well known to be important anti-oxidants, helping repair
cellular and nuclear damage due to free radicals. Linus Pauling, a great
advocate of vitamin C, once noted that humans are the only primate species
that does not produce vitamin C endogenously. And based on the production
of our nearest species relatives in terms of milligrams/kilogram body weight,
he advocated that we humans take between 2 and 17 grams per day. He stayed on
the high side and lived a very productive life until the age of 93.
Vitamin C is one vitamin that you cannot overdose on. Any extra amount that
your body cannot use is excreted, so it is useful to spread out the dosages
over the day. It should also be noted that if you increase the amount you
take too rapidly, a possible side effect is diarrhea, so a gradual increase
is to be recommended, allowing one's body to adjust.
The vitamin A was suggested to me some years back by my dermatologist to
clear up a minor skin problem. It also has good anti-oxidant effects.
However, one can overdose on A, and so should be careful about the doses
taken.
Gingko is noted as helping increase blood flow. This is why it is often
referred to as a memory enhancer (blood flow in the brain). But any improvement
in circulation should also help the body function more appropriately.
The "B-100" is a multi-B-vitamin pill with the following ingredients:

The Ca/Mg/Zi tablet was for general health. I don't remember when or why I
started taking it. I had been taking one aspirin per day as a general
prophyllactic for heart and circulatory problems; it is well-known that
such a regimen decreases one's risk for heart attacks (combined, of course,
with not smoking, eating properly and getting sufficient exercise) as well
as colon cancer [studies that came out in 2002].
This is what I added to my regimen in the first month or so:
- grape seed extract (proanthocyanodin) - 50 mg am & pm
- CoEnzyme Q10 - 50 mg am & pm
- Selenium - 100 mcg am & pm
- generic prostate health pill (see below)
- lycopenes
The grape seed extract was recommended as a potent anti-oxidant by my
acupuncturist, who is also an MD. The CoEnzyme Q10 was recommended by
my chiropracter. CoEnzyme Q10 is more noted as protecting the heart
than anything specifically prostate oriented. [cf.]
It also increases the effectiveness of other antioxidants, such as
Vitamins C and E.
The Selenium amd the lycopenes were recommended by
Dr. Carroll at UCSF. Lycopenes are a chemical found in cooked tomatoes
(as well as some other foods, including strawberries and watermelon) that
are thought to be especially helpful in
fighting prostate cancer. I get most of mine in one 8 ounce glass per day of
a V-8-like juice (Knudsen's Very Veggie is an organic product, Trader
Joe's has Garden Patch, and there is always V-8 itself and
lots of other variations. I don't know the lycopene content of these,
since only Knudsen publishes it on their label.) [Research published in
the May 2006 Journal of Nutrition (Vol. 136, pp. 1287-1293) indicates that
lycopene is most effective when taken along with viitamin E. (See
https://www.webmd.com/prostate-cancer/news/20040930/vitamin-e-lycopene-fights-prostate-cancer
At some point
I switched to getting my lycopenes in pill form to cut back on the amount
of liquids I was drinking.
Selenium is noted as helping the anti-oxidant activity of vitamin E and
should be taken with it. To quote the Life Extension Foundation,
-
"As an essential cofactor of glutathione peroxidase, selenium is an important
antioxidant. It is also involved with iodine metabolism, pancreatic function,
DNA repair, immunity and the detoxification of heavy metals. Studies have
shown that selenium can help prevent some cancers and cataracts."
The generic prostate health pill was suggested by my daughter, who is an
advocate of alternative medicine. These are its ingredients

In March 2001, I added the following items to my regimen:
- Green tea extract (1 capsule = 250 mg ~= 4 cups green tea), one in am
and one at night
- NAC (N-acetylcysteine, 600 mg), one in am and one at night
Green tea is noted for its polyphenols, which are anti-oxidants and thought
to contribute to the low incidence of prostate cancer in Japan, among people
on traditional diets (which are low fat, with lots of vegetables and green
tea). N-acteylcysteine is a source of cysteine, an essential part of the
glutathione antioxidant system.
In March 2002 I added this to my regimen:
- Alpha-lipoic acid (one 100 mg capsule in am and one in pm),
another potent anti-oxidant.
- Soy isoflavones (one 50 mg capsule in am and one in pm)
In February 2007 I added 400 IU Vitamin D twice daily to my regimen. While
this is a small dose, there have been studies of high dose Vitamin D (as
Calcitriol) with erstwhile positive effects on prostate cancer. However,
high doses of Vitamin D can be toxic, so without further research into the
matter, I decided to use a little safely rather than none at all. Later, I
increased this to 1000 IU twice a day, based on research
showing Vitamin D's anti-cancer effects.
In November 2009, I increased my dose of Vitamin D to 2000 IU, twice a day,
based on discussions with an MD. My recent blood levels of D3 were 44 ng/ml
(Oct 2009), whereas suggested values are in the range 50-65 ng/ml (and many
lab tests actually overestimate the blood levels, so perhaps a value of 80
ng/ml may be a reasonble goal).
On 10 March 2007 I started using Peenuts, 2 pills daily, as part of a
study at UCSF to investigate whether this herbal supplement can help
alleviate prostatitis and its consequent underlying chronic (if asymptomatic)
inflammation. Peenuts contains the following ingredients per capsule:

Peenuts was created by a Florida Urologist, Dr. Ronald Wheeler (see
http://www.peenuts.com/), who claims
significant success in reducing prostatic fluid inflammation in men
taking this pill. He has at least one peer reviewed paper on these
studies and is collaborating with UCSF on another study, where MRSI
of both men and their expressed prostatic secretions (EPS) will be
used as measuring modalities. That is, microscopic evaluations of the
EPS as well as MRSI imaging and analysis of the EPS as well as the men
it came from will look for indications of inflammation over time. (See
the discussions below for my history of recurrent prostatitis and for
current theories of how chronic inflammation may give rise to cancer.)
These are the things I stopped taking in September 1999:
I stopped the aspirin in case I might need surgery. Aspirin promotes
bleeding (or slows clotting), good for the heart but not good in healing
from surgery. Somehow, it had not felt right to resume taking it. Here
I went along with my intuition. (Which reversed again in Nov 2000 after
hearing a talk on nutrition and prostate cancer by Mark Moyad, PhD, MD
at a Prostate Cancer Symposium at UCSF; so I'm back to one aspirin a day
as a prophyllactic measure for my heart and circulation. I have also seen
reports that aspirin, as an NSAID [non-steroidal anti-inflamatory drug]
has some anti-cancer properties, another reason to continue taking low
doses on a daily basis.)
Dr. Carroll noted that some cancers feed on Calcium and suggested I stop
taking it as a supplement. I haven't changed the amount I do (or do not)
get from my food, however. (See

- "High Calcium Intake May Increase Risk Of Prostate Cancer", for example,
which is no longer available as of June 2009.)
PollenAid
In late November 2009 I started taking PollenAid (1 capsule in the morning,
1 at night -- although the recommended dose is 3/day) on the suggestion of a
urologist. He referred to peer reviewed studies (which I have yet to receive
copies of) indicating this may be useful in dealing with my underlying
prostatitis. See the references below.
statins
In the autumn of 2000, I also started taking Zocor (simvastatin), 10 mg
per day, since I had mildly elevated cholesterol (starting about 230).
http://www.merck.com/product/usa/pi_circulars/z/zocor.html
In June 2002, my MD switched me to Lipitor (ataorvastatin calcium)
http://www.lipitor.com, since my
liver enzyme tests had begun to creep up the to high normal boundary.
Changing statins is a way to control these, frequently.
I stopped Lipitor after about 9 months, resumed 10 mg of Lipitor in December
2004, and stopped again in February 2005. Blood tests showed good lipid
control with the 2 months on Lipitor, and rising levels in the following 2
months off (early April 2005). In mid-April I began taking Niacin (750 mg
each evening, increased to 1000 mg per evening after 2 months, and then to
1500 mg each evening 8 months later [Feb 2006]; to 2000 mg each evening as of
Feb 2007) to see if that would correct my lipid levels, which it has, for
the most part.
I had stopped taking Lipitor in February 2005, when I experienced some serious
side effects -- syncope (fainting) and banging my head in the fall. This
is when I switched to Niacin for cholesterol control. Since January 2012
I have been taking 1500 mg of Niacin every evening. This has been sufficient
for good lipid control.
The statin drugs, aside from affecting cholesterol and lipid and
trigyceride levels, also seem to have some anti-cancer properties. I
don't have references available.
Naturopath
In October 1999, I saw a Naturopath near Vancouver, British Columbia. I'll
discuss him below, in the section on Alternative
Practitioners. He also gave me a bunch of stuff to take that I added
to my regimen after my PSA test of 27 Oct 1999.

I saw him once more, in December 1999, but shortly thereafter stopped
following his regimen.
Exercise keeps the blood flowing, the endorphins active, the immune system
happy. I had been practicing yoga regularly for about 12 years and have
tried to continue that. I also, for a while, added some aerobic activities.
But I have found it hard, especially over the cold, dark winter, to continue
this with any regularity. Mostly, now, my wife and I take our dogs out for
some vigorous walks a couple of times a week. The frequency tracks
the weather and daylight -- less in the winter, more otherwise.
My diet has gone through a couple of modifications. At first, the general
tendency was to more vegetables and fruit and tofu and less meat. My
lunches consist of a smoothie and some salad and sometimes a small amount
of leftovers from the previous night's dinner. I cut back my coffee to
one cup per day (from 2).
In December 1999, my wife saw Dr. Diana Schwarzbein, a Santa Barbara
endocrinologist, for help with her diabetes. Dr. Schwarzbein has a dietary
approach to dealing with diabetes that seems applicable to health in general.
It is well described in her book, The Schwarzbein
Principle. So for our meals at home, we began following this program,
where I would eat more carbohydrates than my wife.
It was pretty consistent with our general approach although it involves eating
more protein or meat than we were used to. The general principles are
- Stay away from "plastic" foods - anything artificial or processed
(junk food, margarine, sodas, etc.) in order to decrease
the toxic load on your system
- Eat as much organic and natural food as possible
- Eat food that is in season and fresh and grown locally
("Anything that you could pick, grow, hunt, fish for yourself.")
- Balance what you eat at every meal in terms of proteins, natural oils,
vegetables, carbohydrates
- Use only "good" oils, like olive oil and butter and salmon oils in your
food and cooking.
- Any carbohydrates consumed should be whole grain, not processed
- Avoid altogether alcohol, tobacco and caffeine as well as
over-the-counter medications
Additional benefits of this diet are touted to be increase of muscle mass (if
you exercise), decreasing total cholesterol and "bad" lipids (LDL), as well
as a generally healthier body and disposition (see the chapter on serotonin).
By and large, we've always eaten pretty much this way except that we've
increased the amount of organic food in our diet.
In my opinion, Western medicine has a lot to offer the world by taking a
mechanistic analytical approach to understanding how the body functions, from
the cellular level on up. This has been incredibly important in informing
public health measures as well as being able to treat a wide variety of
diseases and conditions and return people to health, alleviate pain and
suffering, and improve quality of life.
However, there are some things lost in its reductionist approach.
One is the realization that the patient is a person rather than a bag of
symptoms. Another is that the person comes from a complex web of history
and social interactions and beliefs. And another is an appreciation of the
ability of the body to heal itself given the stimulus and opportunity and
help to do so. And another is a dismissal of things that do not fit into
its mechanistic picture.
Acupuncture
So I sought to augment my care by seeing three kinds of alternative
practitioners. The first is an acupuncturist. The one I chose was trained
as an MD and came highly recommended. I saw him in order to enhance the
functioning of my immune system, to enable it to fight off the cancer.
At first I saw him weekly, but after a couple of months, I cut down to
once a month. I continued with this practitioner until August 2004.
In February 2005 I started seeing a Japanese acupuncturist (a somewhat
different style than Chinese acupuncture) for about a year.
Chiropractic
The second practitioner I saw was a chiropractor. The idea here was that
if I had any structural issues, subtle or otherwise, that prevented proper
innervation of my organs, that would subtract from my systems' optimum
performance and health, including that of my immune system. The chiropractor
I initially chose was a friend who had recently graduated Chiropractic
College and been
licensed. His practice was just starting out so he had a lot of time to
work with me and explore various possibilities. I saw him about once a week
or so for about 3 months and then stopped when he felt there was nothing more
he could do for me structurally.
In July 2000 I started being treated by a Network Chiropractic practice.
This is a more subtle form of manipulation, more frequent than standard
chiropractic practice, also designed to fully and properly align the
spine and permit proper flow of nerve energy, hence better health and
healing, including enhanced immune system functioning. In March 2001, the
practice moved to another city, which was inconvenient to get to, and I
decided to stop going there and focus instead on more active pursuits,
such as resuming my yoga practice.
Naturopathy
This is a more interesting story. At the first Prostate Cancer Support Group
meeting I went to in September 1999, I replaced another fellow as the
youngest in the group. We got to chatting after the meeting and he mentioned
that he had a friend in Vancouver who is successfully controlling his
prostate cancer through dietary and holistic means.
I contacted the friend via email and then in a long phone conversation.
He had also been trained as a physicist and worked as one for some years
before drifting into the field of government science and development policies.
He was associated with Simon Fraser University in Vancouver and also did
work for the Canadian government as well as consulted with other governments
on these issues. Obviously a person coming from the same Western analytical
approach as I did, at least originally, not one to be easily bamboozled by
various forms of mumbo-jumbo. He had decided upon his diagnosis three years
earlier (1996) that he too wished to avoid surgery and radiation and their
attendant side effects, so sought alternative approaches. Among other things,
he increased the amount of organic and healthy food in his diet. And he
found a local Naturopath as one of his practitioners, an older Dutch
physician who originally trained and practiced as a neurologist for many
years. Eventually, Pieter became a psychiatrist and later on retrained
again as a naturopath and homeopath.
On this recommendation, we booked a business/pleasure trip to Vancouver, one
of our favorite cities, for mid-October 1999. The doctor took some medical
history, and then used an interesting device attached to his PC to
measure balances and imbalances in my body. There are references in the
Bibliography. The technique used is popular in
Europe, unknown in the US, and is
called ElectroAcupuncture according to Voll (or EAV), after its inventor, a
German physician named Voll. He then gave me this list of things noted
above. He also gave me an injection of dead and diluted prostate cancer
cells to boost my immune response, a homeopathic approach.
We saw him again over Christmas 1999. He said I was better but not cured yet
and did more of the same, keeping the medications almost the same.
As I ran out of his supplements during the month of April 2000, I stopped
taking them. We had noted that my PSA had gone down for 2 months before I
started the naturopathic treatments, and so determined that whatever good
they might be doing, they were not crucial to my good health. It was also
expensive and inconvenient to travel to Canada, even a few times a year
(he would have preferred every 2 months). So the next part of the experiment
has been to omit the naturopathic treatments and supplements. I always have
the option of resuming them.
I refer to these next two items as "secret weapons" because they are not
well known or used here in the U.S. for dealing with cancer. Nothing in
the preceding melange of things to ingest or do is unusual or out of the
ordinary. But not many people know about pau d'arco or the use of
human mother's milk. And I will now discuss these elements of my regimen.
pau d'arco
Pau d'arco is a common remedy in South and Central America for a
variety of ills. It is said to be used as an antibiotic, an anti-fungal,
to treat diabetes and skin problems, and to treat cancer, among other
things. It is derived from the inner bark of the taheebo tree,
originally native to the Amazon rain forests, though now found from
Argentina through Costa Rica. Most of the research I was able to come
across about this plant has been done in Argentina and is in Spanish.
Web references follow in the Bibliography.
My younger daughter spent the 1998-1999 academic year studying in Costa
Rica, with an emphasis on alternative medicine techniques. Part of the
time was spent doing an internship on a farm where medicinal plants are
grown using organic, sustainable agriculture. And pau d'arco is
one of the plants grown there. She brought some back to the U.S. and
suggested I take it as a tea when I was diagnosed. Since then, we've
bought a pound at a time directly from the source. It goes a long way.
We've found the tea to be available in some health food stores in
California and over the web, but we've also found that it is difficult
to vouch for the quality of what you're getting. Since
pau d'arco comes from the inner, living, bark (the phloem)
of the tree, often it is adulterated with other barks.
The mixture I get is mixed with some ginger and tumeric, spices also
noted for their medicinal qualities as well as interesting tastes. I bring
a quart of water with 1 teaspoon of the mix to a boil, them simmer 10 minutes
and strain. The suggested dosage is 2 to 3 cups a day, although I seem to
average one to two a day.
One can also buy the tea without the ginger and tumeric or use it to make
an infusion. I don't mind the taste as it is and haven't experimented
with it.
In October 2001 I sent in another order for pau d'arco to my source
in Costa Rica. Six weeks later, my letter was returned for having an
insufficient address, though it used the same address I had been successful
with several times before. Email did not bounce nor did it receive a reply.
And a fax also went through, again with no reply. I had no direct phone
number to call. As I was running low, I decreased the amount I was
drinking to a few cups a week, and gradually stopped taking pau d'arco
as the year ended, with no apparent effect on PSA. I can only conclude that
this tea is not crucial in my program. It may well have helped, but was not
the "Secret Weapon" I originally hoped it might be. In early 2002, my Costa
Rican contact resumed communications (new email address, more complete
postal address) and I am again able to get an ongoing supply.
I stopped taking pau d'arco in July of 2003. I noticed no change in
my condition or numbers without that tea and have come to believe that it
was not an essential element of my regimen.
When I was diagnosed, my wife started doing some research of her own into
cancers. She found on the Web a New York Times article from 19 July 1999
about research into the use of human mother's milk to fight cancer. This
work was being done at Lund University in Sweden and had recently
received a $250,000 grant from the American Cancer Society to continue.
Later on, I found that this article was based on a feature in the June 1999
issue of Discover magazine which explored the discoveries in more
detail. [This article is available on line, as noted in the Bibliography,
or you can visit your local public library to read or photocopy it.]
In brief, about 1994 Anders Håkansson, then a graduate student in
Catharina Svanborg's laboratory at Lund University, found by accident
that adding human mother's milk to a cell culture of cancer cells caused
them to all die. This was true for a wide variety of human cancer cell types.
On the other hand, normal cells were unaffected.
So they injected human tumors into rats. When the tumors started growing,
they started treating the tumors with mother's milk. In most cases the
tumors shrank or died. What seems to be happening is that there is some
combination of factors in the milk that causes "programmed cell death"
or apoptosis in cancer cells and not in
non-malignant cells.
Why would this work? One speculation is that the time of most rapid
post-natal cell growth is the months and year just after birth, when the
normal infant should be nursing. Since rapid cell growth is fraught with
the dangers of bad replication and malignant transformations, a natural
mechanism that would kill such new cancer cells is a reasonable thing to
have developed evolutionarily. In fact, it should be common in all
mammals, one might conjecture.
In fact, it is well known that nursed infants have 1/9 the probability
of contracting any kind of childhood cancer as infants who are not nursed,
as well as having fewer allergies, less asthma, and fewer childhood
diseases.
The Swedes then turned the focus of their research into understanding
the cellular and molecular basis of these observations, doing some good
science in the process. It seemed as if the major factor is something
called MAL, multimeric Alpha-Lactalbumin, along with
some potentiating factors. They found that pastuerization destroys the
multimeric character of this compound and also its cancer-killing abilities.
Their focus, however, is to isolate and patent the factors, then to license
them to drug companies and live well on the royalties.
My reasoning was quite the opposite. If the potent parts of mother's milk
can get into the infant's body via his/her gut, it is very likely that
the same is true for an adult who ingests it as well. True, with a much
larger body weight and size than an infant, there would be a greater
dilution, but any apoptosis than can be induced over as long a period of
time as the milk is available would help keep the cancer under control
or even, in the best of worlds, eliminate it.
I contacted Dr. Håkansson by email and received copies of three
of their research papers (in English).
Shortly after we found the New York Times article, we reconnected with
a colleague I had worked with some years previous. His wife was nursing an
8 month old and she herself was a cancer survivor. She agreed to pump
her breasts for me. So from late August 1999 for almost a year, I had
a supply of mother's milk, which ended when my donor weaned her child.
I am endeavoring to continue having a supply from healthy, health-conscious
women.
Almost every day (depending on the supply), I took about 2 ounces of
mother's milk mixed into a smoothie (orange juice, yogurt, tofu, various
fresh and frozen fruits) as part of my lunch. It is a simple, healthy, and
palatable way to take this part of my regimen.
I believe that these two items, but mostly the mother's milk, have made
the difference for me in keeping my cancer under control and my PSA
scores down in the mid-normal range. Everything else has helped, to a greater
or lesser degree, but this "secret weapon" has been the crux of it all.
While pau d'arco is mildly difficult to get, it is available. Mother's
milk, on the other hand, requires some luck or connections. It is a
hypothesis I made that the same positive anti-cancer effects can
also be obtained from certain kinds of raw mammal milk, perhaps goat or
cow, perhaps some more closely related species. The key word here is
"raw", since pastuerization (heat) destroys the effect, and raw milk might
come with its own health concerns. It would be interesting and quite useful
if some academic, less motivated by greed, would pursue this line of inquiry.
In July 2000, my source of mother's milk told me she was planning on weaning
her child, which was a perfectly reasonable thing to do. My wife found a
possible source via a Milk Bank, but they needed a prescription from an
MD to give me the milk, only because providing milk to adults was not a
usual course of action. So, in mid-July I asked my urologist for one.
In the meantime, I had received the April 2000 PNAS
paper from the Swedish researchers. In it, they had isolated the essential
cofactor in human mother's milk that caused multimeric alpha-lactalbumin
to undergo its shape changes into the form that kills cancer cells. This
cofactor is oleic acid, which I then discovered was abundant in olive oil.
While waiting for the prescription, I experimented using raw cow's milk
from a health food store instead of the no longer available mother's milk,
adding in about 1 cc or so of olive oil. I also increased the amount of
cow's milk to 4 ounces a day, from the 1 to 2 ounces of milk that my donor
had been pumping, on the average.
This did not work. After about 1 week of the new regimen, the PSA on 10
August was a consistent 2.2. About 4 weeks later, on 8 September, it had
increased to 3.8! This is a doubling time of about 6 weeks.
Again, I requested a prescription from my urologist, but he wrote back
"...I have no experience with prescribing mother's milk and do not
feel comfortable prescribing something I know little about...."
So I found two other MDs who would support me and who wrote me the
prescription. The folks at the Milk Bank were wonderful and fully aware
of the Swedish research. The director had spent a few hours the previous
month (August 2000) talking with the discoverer of the effect and a key
researcher on the Lund University team at a conference in
Washington, DC and was already supplying the milk to a few small and
successful pilot studies in other parts of the country (that is, individuals,
such as myself, with various forms of cancer).
Within one week, my PSA had dropped to 2.5 ng/ml, and I was greatly relieved.
Since nothing else had changed in my regimen, it became abundantly clear that
the crucial factor in controlling my cancer was the milk. Everything else
may help, but nothing else was sufficient unto itself to keep my PSA down and
the cancer under control.
(According to their papers and personal communication, the oleic acid, in
the warm, acid environment of the human gut, transforms the physical
conformation (or shape of the molecule) of the multimeric alpha-lactalbumin
molecules into another form they call HAMLET [for Human
Alpha-lactalbumin Made LEthal to Tumors],
which induces apoptosis in malignant cells.)
This experience leads to some additional questions:
- Was the amount of oleic acid I used too little?
- Are cow and primate alpha-lactalbumin different enough so that the
bovine variant is not transformed into HAMLET?
- Are other necessary but so far unidentified cofactors present in
primate milk but lacking in bovine milk?
The milk from the Milk Bank is pasteurized. According to Dr. Håkansson,
the process they use, required by California state law, will degrade some,
but not all, of the apoptotic activity of the milk. For that reason, I
was using 7 ounces a day of the Milk Bank's pasteuerized mother's milk.
[Aside about another's experience]
One of the men in my prostate cancer support group has been using dietary
means to keep his PSA about 3.5 ng/ml for some time. Based on my experience,
he got a prescription for mother's milk from his physician and used about 7
ounces per day for 2 months. He was disappointed that he did not see any
notable decrease in his PSA and so stopped the experiment.

Strange PSA values in May 2001
Three weeks after the MRI/MRIS of April 2001,
before I had those results in hand (UCSF was understaffed in the Radiology
Department and was quite behind in making timely interpretations of the
images), I returned to Stanford University Hospital for my monthly PSA
test. On 9 May 2001, the value was 19.6 ng/ml. This was an astounding jump
from the 2.6 it had been 5 weeks previous. Did the lab make a big mistake?
Had the Milk Bank changed how it processed milk? What else was going on?
Had the cancer exploded?
I went back two days later, on 11 May 2001, to repeat the test. It came back
as 14.0 ng/ml. Curiouser and curiouser. Is a drop of 5.6 ng/ml in two days
reasonable? The numbers were frightening and did not make a lot of sense
until I got the MRI report. As noted above, it showed (marginally) less cancer
than in previous images, but also noted evidence of prostatitis, something
which could account for these PSA values. My urologist suspected prostatitis
as the cause of these readings and put me on antibiotics. After one week,
the PSA went down to 4.0 ng/ml. We decided, after a week break, to do another
week's worth of Cipro (500 mg), which brought the PSA back to 2.5 ng/ml,
roughly where it had been before the infection.
Apparently, prostatitis may be asymptomatic, though rarely. Reviewing the
original biopsy report of July 1999, it stated that there was evidence
for my having had prostatitis (apparently it permanently affects some
noticeable characteristics of the prostate cells it infects) and I may
well be harboring a latent infection which occasionally flares
asymptomatically. There is some sense of relief, but also one of mystery.
By the way, the Milk Bank claimed no changes to its processing/pasteurization
protocol.
Raw Milk Again
The anomalously high values of early May 2001, due to prostatitis, put a
scare into me and also concerned the folks at the Mothers' Milk Bank. The
Director began to investigate what it would take to get me raw milk. She
attended a conference in Vancouver in June of all the North American
milk banks and found that nothing in the organization's charter or by-laws
prevented the distribution of raw milk, as long as appropriate releases were
signed. She checked with the California Department of Health, which also
had no objections, provided appropriate informed consent was available.
She requested generic release forms from the local blood banks, modified them,
and had the organization's attorney (a former milk donor) and medical
director approve them. And finally, on 9 August 2001, almost 3 months
after the first high PSA reading, I was able to get a batch of raw milk.
The Milk Bank routinely screens all donated samples for bacterial count.
The biochemist had started sequestering samples with extremely low counts
for me. The bacterial levels in these is equivalent (or almost) to those
in pasteurized samples. Naturally, all donors are screened via blood tests,
when they sign on, for an array of potentially transmissable diseases. So
the milk, raw or processed, is likely quite clean. I have no need to fight
off cancer to catch some other disease.
A week and a half later, a PSA test gave the value of 1.9 ng/ml, equivalent to
my "normal" value of December 1997 and among the lowest values I have had,
even though I halved the quantity of milk I was using (from 7 ounces/day of
pasteurized to 3.5 ounces/day of raw milk). This is very encouraging.
Strange PSA values in January 2002
This seems to have been another case of asymptomatic prostatitis, since it
responded to a course of Cipro I started on 23 January. On its own, my
PSA came down rather quickly from 8.67 to 5.45 and stabilized there for
a week. After less than a week on Cipro, it was down to 4.01. I got enough
Cipro for a 2-week course, and renewed it for another 2 weeks.
It is apparent to me that cancer and BPH do not behave this way, spiking and
dropping, as my PSA did in May 2001 and again in January 2002. Certainly,
Dr. Carroll also seemed unable to explain this behavior. And Dr. Kurhanewicz
pointed out that the increased activity in the MRIS of 9 January 2002
might be attributable to an acute stage of prostatitis rather than increased
cancer metabolism. He mentioned that he had only seen this twice in the
4000 or so images he has looked at over the years, since most prostatitis
he sees is chronic, and so has less metabolic activity. This seems to be
the explanation.
Strange PSA values in the winter and spring of 2005
The spike in Dec 2004 (6 weeks after a 2.17, a value of 6.45, which fell
on its own to 3.37 two weeks later and 3.29 a week and a half following) are
again not typical of prostate cancer. Rather, they are signs of an infection.
In consultation with my urologist, I started on a prophylactic 4 week course
of Cipro on 31 Dec 2004. Our plan was to wait about 2 weeks after it was
finished to do another PSA measurement.
About 10 days after I finished the Cipro, I had the symptoms of a prostatitis
attack, including painful and frequent urination. Blood work showed a raging
infection. So I started a 2 week course of Floxin, another antibiotic in
the same family as Cipro. It took a few days for the symptoms to abate, but
they did around mid-February.
On 28 March 2005, I went for another PSA and my first free PSA measurement.
The result is expressed as a ratio of free (or unbound PSA) to total PSA
(that is, to bound plus unbound PSA). Values below 10% are indicative of
cancer (>40% probability of active PCa); values above 25% are indicative of
no active cancer (<10% probability), for PSA values in the range of 4-10 ng/mL.
Mine was 15%, in the ambiguous range. [A conversation with Nanette Perez, RN
at UCSF Urologic Oncology on 3 April 2013 led to the rule of thumb that
free PSA > 20% is considered to indicate no cancer present.]
Since Stanford sends the Free PSA to an outside lab to be processed, I
figured the PSA value was not comparable to most of the others, so I
redid my PSA on 05 April 2005. It was significantly elevated from the
value of the previous week, indicating to me that I was still harboring
an infection (which was thankfully asymptomatic). Further followup was
due with a power doppler TRUS on 11 April and a consultation with my
urlogist the following week.
The TRUS showed no changes from the previous year or the year before
and no obvious signs of cancer, which was reassuring. My uroligist
agreed that I still had prostatitis, that I was lucky to be symptom free,
and that chronic infection was problematic for several reasons:
- it masks my "true" PSA levels, making it impossible to track
the state of my cancer via blood tests;
- it makes any MRSI invalid since prostatitis signals in the
spectroscopic images look too much like prostate cancer to be
able to clearly differentiate the two; and
- chronic infection itself can lead to cellular and DNA damage
and hence possibly more normal prostate cells making a
transition into a malignant state. (See
a discussion below on this issue.)
My PSA values continued to jump wildly about, 4.42 in June, 18.3 in
July, and then settled back to normal at 2.44 in early August, for
reasons that elude me. Somehow, the infection has (hopefully) run
its course and is done.
PSA Decline since the COVID pandemic started
In February 2020 my PSA hit a peak of 14.5 mg/ml, but has been declining since
pretty consistently. This is a good thing, but I have no idea why this is
happening. The COVID pandemic started in mid-March 2020 with its attendant
shelter-in-place regimen and I spent most of my time at my significant other's,
which led me to decrease my ingestion of mothers' milk to once a week (from my
usual twice a week -- see Dosage Summary below). The size of my prostate, as
determined by my annual MRSIs, while continuing to increase, has done so much
more gradually as well in this time frame. (See
below). It is curious.
Dosage Summary
Here's a summary of what I had been taking over time:
- August 1999 - July 2000: raw milk from my donor, approximately
2 ounces per day; the amount varied
- August 2000: organic cow's milk mixed with olive oil for the oleic
acid, about 4 ounces per day. This did not successfully emulate
human mother's milk.
- September 2000 - June 2001: pasteurized milk from the Milk Bank,
7 ounces per day (two 3.5 ounce bottles) during most of this
time, one bottle per day during some of this time.
- July 2001 - December 2002: raw milk from the Milk Bank, one
3.5 ounce bottle per day; 2 bottles per day for a few months
during this time.
- January 2003 - September 2003: one bottle of raw milk from the Milk Bank
every other day.
- October 2003 - April 2013: one bottle of raw milk from the Milk Bank
two times a week.
- Approx April 2013 - March 2020: one bottle of pasteurized milk from the Milk
Bank two times a week. (The Milk Bank stopped making raw milk available
around this time.)
- April 2020 - present: one bottle of pasteurized milk from the Milk
Bank once a week, most weeks. Ocassionally, two bottles a week. This
was due to "sheltering in place" during the pandemic at my significant
other's home much of this time.
So, what conclusions can one draw from all of this? What might be applicable
to you, another person diagnosed with prostate cancer, or a friend or
relative of such a person? There are a few things I can say, but, as
usual, your milage may vary -- that is, your results may not be the same
as mine and you need to exercise your best judgement in the end.
PSA Improvement
Mine was much better and much faster than I had expected. As discussed above,
a very conservative linear model would have put mine about 6.2 ng/ml at the
time I was diagnosed. And I only started putting my regimen together over
the following month. Hence, I expected my PSA, as measured at the end of
September 1999, to be roughly where it was at the time of diagnosis or a little
lower. I thought it would have continued increasing for a while and, at
best, had a short period of time to start reversing, if what I was doing was
really effective.
Instead, it came down to "normal" (1.9 ng/ml) right away and more or less
has stayed at 2.0 +/- 10%. This was quick; I was suprised and pleased.
What is the "magic bullet"?
I don't know. I suspect it is the mothers'
milk. But there is no way of really telling unless I start cutting things out.
However, I have no desire to do that experiment on myself. In general,
I subscribe to the philosophy of "If it ain't broke, don't fix it."
Since I started the Naturopathic remedies relatively late in the game (at
the end of October 1999, when I already had 2 or so low PSA's), I know that
these were not decisive. They may well have helped sustain the effects of
everything else, but were not the crucial elements in controling my PSA levels.
My experience in August and September 2000, when I did not have access to
human mother's milk but everything else in my regimen stayed constant, as
discussed above, leads me to now believe that the mother's milk is the
crucial aspect of my program, the "magic bullet". It seems insufficient,
so far, to eliminate the disease, but capable of holding it at bay, as
indicated by my monthly PSA results and validated by the semi-annual
MRI/MRIS imaging. (Actually, according to the history of my MRSI images,
discussed above, it seems that my cancer has been essentially undetectable
since around 2002, only 3 years into my regimen. I write this aside in
2019, 20 years after diagnosis when it seems obvious to me that human
mothers' milk is indeed the "magic bullet" for eliminating my cancer.)
I stopped taking the pau d'arco in July 2003, with no noticeable
effect on my TRUS (Aug 2003) or subsequent PSAs. I currently don't
think this is a "magic bullet", although it may well have some positive
medicinal effects.
How General is This?
Again, I don't know. With a data set of one person, it is impossible to
generalize on how well this would work for another person or, if so, how
quickly it would work. In that sense, my experience is anecdotal. That means
it is useful; it is, as we said in math classes, an existence proof. But
it does not guarantee that the same will happen for every (or any) other
man who tries this all. (Some small pilot studies by the Swedes -- with
human glioblastomas, bladder cancers and colon cancers -- indicate
possible potent effects of HAMLET in vivo. See the Bibliography
for the peer reviewed articles.)
How Long Will it Last?
Again, time will tell. So far, we know that my PSA went way down very quickly
and has stayed in mid-normal ranges for over 4 years (as of this writing).
The results of all my MRI Spectroscopies are discussed above. (As I add
this aside, it has been 20 years since my diagnosis and I am cancer free;
or, more precisely, any cancer in my system is undetectable.)
What should you do?
Obviously, you should do what you think is right for you, is best for you,
is most appropriate for you. One should not take cancer lightly. On the
other hand, MDs have their own prejudices about what the most appropriate
approaches are ("If the only tool you have is a hammer, everything looks
like a nail") as well as a strong financial incentive to treat you with
their technologies. On the other hand, wishful thinking is no substitute
for action, usually.
You need to understand your own health, your own unique personal conditions
and values, the stage and aggressiveness of your cancer, and what all the
(rapidly changing) medical options that are available to you may be. And
you may often have to fight an unresponsive medical bureaucracy or HMO or
insurance company that has only its owners' bottom line at heart, not your
well-being or even survival. A large and daunting task for anyone, no doubt,
but do-able.
Another caveat is that if you have any Gleason 4 or above in your
biopsy samples, you will need to do more than only lifestyle changes.
According to a paper by Professor Thomas Stamey of Stanford University
Hospital [ref needed!], the strongest negative indicator of
survival time is the percent of Gleason 4 or higher in one's biopsy samples.
In this case, informed medical action is appropriate along with lifestyle
and dietary changes. Even in this case, give yourself enough time to get
past your shock, to become informed enough about all alternatives, and to
find the best practitioner of the approach you decide upon.
In any event, do not try my approaches instead of medical
modalities if your cancer is spreading, growing, creating symptoms, or
otherwise showing signs of aggressiveness. All of this can be used as an
adjunct to more conventional therapies, if necessary. Remember, I am not
practicing medicine, I am presenting my own personal story and discoveries
and you are, in the end, the only one responsible for your own health,
along with those experts you hire to inform and assist you.
Aggressive Monitoring (aka Active Surveillance)
One doesn't just set a course and assume it is working. I have taken an
approach of aggressively monitoring my cancer, as best I can. This means
having a monthly PSA blood test (versus once every three months, as proposed
by my urologist). It also means having an MRI Spectoscopy every 6 months or
so (versus the once a year suggested by my urologist).
Other tests are available. These include the DRE (digital rectal examination),
the TRUS (trans-rectal ultrasound), biopsies and other blood work. In my case,
I don't think these would tell me anything, mostly because they didn't before.
That is, my cancer was so small and early stage, it was invisible to the DRE
and TRUS I had in July 1999. And the biopsies are like poking into a haystack
with a needle, looking for a pingpong ball. Or perhaps a marble. If the target
is small enough, one has a very small likelihood of poking into it with a
few at random stabs. Finally, the blood work (such as Free PSA and other
enzymes) merely serve to indicate the likelihood of cancer; since we know
that cancer exists, these also would not yield new information.
I have more confidence in the MRIS, in my case, because it can image
everything (bigger than some minimum, of course) and differentiate cancer
from non-malignant tissue. I also have a "before" for comparison, a "before"
that showed the location and extent of cancer, so we will be able to see
its progression or regression.
Simple Conclusion
The approaches I have outlined here cannot hurt as supplements to more
traditional, medical, or conservative approaches or to "watchful waiting".

From their FAQ page: "Quertle goes beyond simple term matching to
identify the most salient information in the literature. Using a
combination of linguistic methods, Quertle finds facts defined
within documents, creating its own database of about 250 million
relationships, and is able to report the ones that are relevant to
your query. Quertle's approach is based on a thorough understanding

The PRIAS Project is a Dutch-based research poject with a focus on
following men with non-aggressive prostate cancer with active
surveillance, using frequent PSA measures, twice yearly M.D.
visits with DREs, and biopsies at years 1, 4, 7, 10, 15, etc. If
the cancer is obviously progressing, "standard" medical treatments are
then pursued. They have collaborating doctors in Europe and Canada.

More Men With Early Prostate Cancer Are Choosing to Avoid Treatment,
By Gina Kolata, (24 May 2016)
"Seemingly overnight, treatment of men with early-stage prostate
cancer has undergone a sea change. Five years ago, nearly all
opted for surgery or radiation; now, nearly half are choosing
no treatment at all.
The approach is called active surveillance. It means their cancers
are left alone but regularly monitored to be sure they are not
growing. Just 10 percent to 15 percent of early-stage prostate
cancer patients were being treated by active surveillance several
years ago. Now, national data from three independent sources
consistently finds that 40 percent to 50 percent of them are making
that choice...."

One interesting aspect of this study was the conversion of bovine
alpha-lactalbumin to a cancer killing form (BAMLET) with a C18:1
fatty acid (which is not present in cow's milk but is abundant in
human milk). BAMLET was not as effective as HAMLET in inducing
tumor cell death.

From the Abstract:
A complex of human alpha-lactalbumin and oleic acid (HAMLET) was
originally isolated from human milk as a potent anticancer agent. It
kills a wide range of transformed cells of various origins while
leaving nontransformed healthy cells largely unaffected both in vitro
and in vivo. Importantly, purified alpha-lactalbumins from other
mammals form complexes with oleic acid that show biological activities
similar to that of HAMLET...

Nine bladder cancer patients received 5 daily instillations of HAMLET
during the week before surgery. HAMLET stimulated a rapid increase in
the shedding of tumor cells into the urine, daily. Most of the shed
cells were dead and 6 of 9 patients showed an apoptotic response. At
surgery 8 of 9 patients showed a reduction in tumor size or change of
tumor character. Adjacent healthy tissue showed no negative changes.

Peroral HAMLET administration reduced tumour progression and
mortality in ApcMin/+ mice. HAMLET accumulated specifically
in tumour tissue, reduced β-catenin and related tumour markers.
Gene expression analysis detected inhibition of Wnt signalling
and a shift to a more differentiated phenotype. In colon cancer cells
with APC mutations, HAMLET altered β-catenin integrity and
localisation through an ion channel-dependent pathway, defining a
new mechanism for controlling β-catenin signalling. Remarkably,
supplying HAMLET to the drinking water from the time of weaning also
significantly pevented tumour development.

From the Abstract: "...This review presents the state of knowledge of
the anti-cancer aspects of HAMLET-like compounds, the HAMLET-induced
cytotoxic activities to cancer and non-cancer cells, and the several
prospective cell membrane and intracellular targets of the HAMLET
family. The emerging picture is that HAMLET-like compounds initiate
their cytotoxic effects on what may be a cancer-specific target in
the cell membrane that has yet to be identified."

Breast-Feeding Benefits Mothers, Study Finds (see next reference)
"Most doctors agree that breast-feeding
is best for babies' health. Now a large study suggests that the practice
benefits mothers as well: women who have breast-fed, it says, are at lower
risk than mothers who have not for developing high blood pressure, diabetes
and cardiovascular disease decades later, when they are in menopause."

Published Online: 1 Apr 2009
"[T]he current data are indicative that a diet low in fat, high in
vegetables and fruits, and avoiding high energy intake, excessive
meat, excessive dairy products and calcium intake, is possibly
effective in preventing PC. However, caution must be taken to ensure
that members of the public do not take excessive amounts of dietary
supplements because there may be adverse affects associated with their
over consumption. The dietary recommendations for patients diagnosed
with PC are similar to those aiming to reduce their risk of PC." The
review also found there is evidence that eating healthier may help slow
tumor progression in men who have prostate cancer.

How You Nurture Your Health Could Change Your Genetic Nature,
David Katz, M.D. (Dr. Katz is the Director of Yale University's Prevention
Research Center) (August 20, 2010)
In this post, Dr. Katz discusses research by Dr. Dean Ornish and UCSF
showing how diet and lifestyle affect gene expression in tumor cells --
following the Ornish program for 3 months had post-program prostate
cancer biopsy samples compared to pre-program prostate cancer biopsy
samples. "Roughly 50 genes associated with cancer suppression became
more active in generating RNA, and nearly 500 genes associated with
cancer progression became less active. The pattern of change observed
in gene activity was consistently, and decisively associated with lower
risk of cancer development and progression."

levels of vitamin D reduce the risk of developing prostate cancer and
may help suppress the growth and spread of prostate cancer cells in men
who already have it. A significant proportion of older men have
suboptimal levels of vitamin D, especially during the winter and spring
months. But boosting your vitamin D levels isn't difficult.... When
choosing a supplement, look for one that contains vitamin D3, which is
more effective than vitamin D2."

Prostate Cancer: Low-Cost Interventions, a summary of some
results from the 2012 American Association for Cancer Research meeting.
Discusses Vitamin D, Metformin, treating obesity, and some new drugs
for Castration Resistent Prostate Cancer. In particular, those men on
higher doses (3 groups, 400 IU/day, 10,000 IU/day and 40,000 IU/day)
had better markers for less metastasis and slower cancer growth, with no
adverse effects at any dose. (There were only about 20 men with Gleason
6 or 7 in each group, and they used the Vitamin D for 4 to 8 weeks before
radical prostatectomy. At higher doses, blood levels should be checked
periodically and should remain less than 100.) A study cited found
higher blood levels decrease the risk of aggressive PCa.

seven months, roughly double the life expectancy of chemotherapy alone
in hormone resistant prostate cancer. The drug is given in conjunction with
docetaxel and prednisone, and serves to inhibit the production of a gene
protein called clusterin that protects cancer cells from cancer treatments,
such as radiation and chemotherapy.

PSA Controversy
- There has been an on going controversy on the overall utility
of PSA testing and whether too many men with indolent cancer have their
prostate cancers detected with this test, are treated when it is
unnecessary to do so, and suffer the expense and side effects of
treatment; or whether enough lives are saved by earlier detection
for the PSA test to be promoted. Certainly, better tests which
could indicate which cancers were aggressive and which indolent are
to be desired.

Two major PSA test kits were used to evaluate samples from over 200
men. Significant differences were found in the results of the kits
versus each other and within each manufacturer's assay, depending
on the lot of test chemicals used. The variations were in the
10% range overall.

Men without prostate cancer who had initial PSA in the 4.0-10.0
range were tested twice within 2 to 3 weeks. The variation from
first to second sample was 23.5%; when the first sample was retested
at the time of the second test, the variation found was 10.5%.

PSA was followed in 49 men with prostate cancer who used "watchful
waiting". PSA was measured roughly every 6 months. No correlation
was found with rate of increase and any other factor (age, stage,
etc.). Significant variability was found in the rate of change.
The most interesting result, of which there was no followup or further
investigation, was that in 22% of the men in the study, the PSA levels
decreased during the study with no medical intervention.

A sample of 949 men from a prostate cancer screening program who had
no signs of cancer were studied with 2 or 3 PSA measurements taken
2 to 3 years apart. They found significant variation within individuals
over time, but all within normal ranges. Overall, the values were
fairly constant (PSA velocity approximately 0.0 ng/ml/year).

Terry Herbert of Melbourne, Australia, for pointing them out.) Aside
from providing some additional background on PSA, they indicate that
non-prostate tissue can generate the protein, but in much smaller
quantities than the prostate gland does and some may be found in
human breast milk.

Prostatitis Center, Tucson, Arizona
A medical practice centering around the treatment of prostatitis
using a combination of prostatic massage and appropriate antibiotics
(based on a pathologist's examination of expressed prostatic secretions).
The approach of using deep prostate massage to empty the sacs and
make them accessible to antibiotics or other medications seems to be
more used in Europe and Asia than in North America. This center seems
to have closed in 2014, as this Internet Archive site image is the
final one. However, the internal links to treatment philosophy and
methodology still work (in the Internet Archive saves). (24 Feb 2021)

Lou Surette's site on how to cheaply and easiy "clean out the plumbing"
of your prostate using Sitz baths, an intriguing idea. He argues that
this simple procedure can decrease the chances of prostatitis, BPH
symptoms, and the possibility of prostate cancer. He's also an
advocate of appropriate diet and supplementation. He seems to have
created this site in early 2003. In May 2003, he was diagnosed with
Chronic Lymphatic Leukemia (CLL) and began a separate web site to blog
his experiences (

- Google returns 5,700,000 entries for "prostatitis" (8 July 2019).
It is interesting to note that the embryonic tissue that gives rise to the
prostate gland in male children gives rise to two small glands that
surround the female urethra -- the Skene glands and the paraurethral
glands. These glands also stain positive for PSA. It is thought that
their inflammation, a kind of female prostatitis, is one of the causes
of female urethral syndrome. Females with these disorders suffer the
same symptoms of urinary frequency, pain with urination, and pelvic
pain, that men with prostatitis have. See

Biopsy Readers
There are several world-class experts in reading prostate cancer biospsy
slides in addition to Dr. John McNeal, mentioned above. It might be prudent
to have your slides sent to one of these folks to get their readings.
A correct Gleason score, number of positive cores, and percentage of
the cores that are positive are important factors in helping to decide
the extent and aggressiveness of one's cancer and hence the appropriate
course of action.

Men who underwent prostate biopsy were more than twice as likely to
be hospitalized within 30 days compared with men who did not undergo
the procedure, a study of Medicare beneficiaries showed. Procedural
complications, such as infection and bleeding, as well as
exacerbations of comorbid conditions contributed to a
hospitalization rate of 6.9% following prostate biopsy versus a
2.9% hospitalization rate for controls....

I'll define a few terms used above that may not be obvious to a reader who
is not conversant with prostate cancer. Please email me any others you
think should be in this list.
[A more extensive prostate cancer glossary is available at
http://www.phoenix5.org/glossary/glossary.html, part of
Robert Young's Phoenix5 site, referenced above.]
Other Glossaries:
- apoptosis
Programmed cell death. The biological process where a cell can
"commit suicide". This is a normal part of the cell cycle at
all stages of development, for some cells, and may be part of
the aging process. Research has shown that human mother's milk can
induce cancer cells to undergo apoptosis while leaving non-malignant
cells unaffected.
It should be noted that other chemicals and drugs may also induce
tumor cell apoptosis. To my (limited) knowledge, some of these are
in various experimental or pre-clinical stages, but all have side
effects of one sort or another. I do not believe that mother's milk
has known side effects and it is currently available, whereas
alternatives are not.
Necrosis is non-programmed cell death, usually due to outside
factors, such as radiation or attack by toxins. In the case of
necrosis the cell does not have time to orderly shut down. It
appears differently than an apoptotic cell.
- BPH
Benign Prostate Hyperplasia. A benign condition of the prostate,
usually occurring in older men, which causes the gland to grow or
swell beyond its normal size. This often squeezes the urethra,
which passes through the middle of the prostate, causing urinary
difficulties. Prostate cancer, too, can squeeze the urethra, and so
it is important to differentiate these two conditions.
- DRE
The Digital Rectal Exam. The physician puts on a latex glove and
lubricates it, then inserts his finger into the patient's rectum,
probing the prostate gland. In general, he is looking for hardness,
lumps and other abnormalities on the back wall of the prostate,
which is right next to the rectal cavity. Most early stage prostate
cancers that are palpable (that is, can be felt in this exam) occur
in this region of the prostate. Until the PSA test was invented in the
mid-1980's, this was the only way to detect prostate cancer.
- Free PSA
(See PSA.) Prostate Specific Antigen may
be found either bound or free in the blood. The standard PSA value
is the total PSA found, in nanograms per milliliter. The greater
the percentage of unbound, or free, PSA, the less likely one is
to have prostate cancer. The rule of thumb is that free PSA
greater than 20% or so means one is unlikely to have prostate
cancer and so may be spared a biopsy, for moderate ranges of
total PSA. Once a biopsy proves cancer is present, the free PSA
test no longer provides information of value.
- HAMLET
Human Alpha-lactabumin Made Lethal
to Tumors
The shape modified form of human alpha-lactalbumin that causes
cancer cells to undergo apoptosis.
- MAL
Multimeric Alpha-Lactalbumin. Lactalbumin is a protein found in
milk. In raw milk, it exists in both its monomeric form and in
multimeric forms. Pastuerization breaks the multimeric forms down
so that pastuerized milk only contains the monomeric form.
A monomer in chemistry is a single unit. When a number of these
single units are bound together, this is called a multimer. Just
noting that something is multimeric does not say what the
fraction is that is 2-meric, 3-meric, etc.
MAL in human mother's milk has been found to cause cancer cell death
(apoptosis) in vitro (in the test tube). The researchers at Lund
University also found that certain cofactors in the mother's milk
(oleic acid) are also required for MAL to be effective as a cancer
killer.
- MRIS
Magnetic Resonance Imaging and Spectroscopy. Also called MRSI,
for Magnetic Resonance Spectroscopic Imaging.
MRIS is an imaging technique which uses strong and rapidly
oscillating magnetic fields to image noninvasively soft body
tissues in three dimensions at fairly high resolution. For
current prostate magnetic resonance imaging, the resolution of
a pixel is 0.5 x 0.5 mm, with virtual slices every 3 mm.
The spectroscopy component, done at the same time as the imaging,
has a coarser resolution, roughly cubes about 6mm on a side.
The spectral results
can be overlaid on the image to correlate cancer, BPH, necrotic
(dead) cells, and normal cells with the image.
- PSA
Prostate Specific Antigen. A chemical
produced almost exclusively by prostate
cells and prostate cancer cells. Its level increases gradually with
age and prostate volume, but is expected to be between 0.0 and
4.0 ng/ml. Higher values
and/or rapid increases can indicate prostate cancer. Higher values
might also indicate BPH or prostatitis. Cancer can exist at low
PSA levels. In general, however, it is thought of as a good
proxy for cancer levels.
Healthy prostate cells also produce PSA. A rule of thumb for what
one's "background" PSA should be if all cells are healthy is to
multiply the gland volume in cc by 0.066. For example, my gland's
volume on 22 July 2002 was 36 cc, as measured in an MRI. The
background PSA level should have been about 2.38 ng/ml; my
measured PSA was 2.16. [This value of 0.066 ng/ml/cc comes from
the PCRI (
http://www.prostate-cancer.org/)
newsletter PCRInsights, vol 5, no 1, July 2002,
page 7. All isues may be downloaded in PDF format from
http://www.prostate-cancer.org/resource/insights.html]
- TRUS
Trans-Rectal UltraSound. An imaging technique involving an ultrasound
probe inserted into the patient's rectum, enabling imaging of the
prostate and surrounding regions. The resolution (at least to me)
seemed fairly crude and the images blurry and distorted, but the
radiologist doing the exam seemed to be able to read them easily.
TRUS is often done in conjunction with a prostate biopsy and is used
to guide the biopsy sampling. It can also measure the prostate volume,
that is, the size of the gland.
A good review of TRUS, both historically and in guiding biopsies,
can be found in the Bibliography.

cancer.

Scope of the Issue
"The American Cancer Society estimates that 198,100 men in the United States
will be diagnosed with prostate cancer during 2001. The group estimates
prostate cancer will kill 31,500 men in the United States in 2001, making it
the second-leading cause of cancer deaths in American men after lung cancer.
More than 70% of all prostate cancers are diagnosed in men older than 65
years. Early diagnosis using the prostate-specific antigen (PSA) test and
digital rectal exams means the 5-year survival rate for men with
prostate cancer has increased from 67% 20 years ago to 93% today." (This
paragraph is quoted from a news release on Medscape about the article
Nature Genetics 2001;27(2):172-180 (6 Feb 2001)).
The corresponding 2003 figures are "more than 220,000" men being diagnosed
with prostate cancer in the U.S, "nearly 30,000" dying from it. (From a
Seatle Times story on 15 April 2003, no longer available online.) A New York
Times article
(http://www.nytimes.com/2003/12/23/health/23CANC.htm) notes that the
U.S. 2003 incidence will be 220,900 cases with 28,900 deaths and 1.8
million men living with the disease.
The American Cancer Society's 2004 estimates are 230,000 men diagnosed,
almost 30,000 deaths (from http://www.hon.ch/News/HSN/518884.html, but this
site seems to have removed all archives before 2008).
The American Cancer Society's 2005 estimates are 232,000 men diagnosed,
and 30,000 deaths (from
http://www.nytimes.com/aponline/AP-FIT-Prostate-Cancer-Obesity.html,
9 Jan 2006 -- no longer available on line or in the Internet Archive -- 13
March 2021).
"The National Cancer Institute of Canada estimates that 17,800 Canadian men
will be diagnosed with prostate cancer in 2001, making prostate cancer the
leading cancer diagnosed in Canadian men." (From
http://www.isip.com/press/press01/112601-Oncogenex.htm, a press release,
26 Nov 2001, no longer available on the www.isippharm.com web site as of
June 2009.)
"Prostate cancer is on course to become the most common men's
cancer in Britain in the next 3 years, health experts said on Monday.
Cases of the disease have doubled in the past 20 years and scientists
predict the numbers will continue to rise as the population ages and
more men are tested for the illness. ... Around 22,000 cases of prostate
cancer are diagnosed in Britain each year and 9,500 men die of the
disease annually." (Originally from
http://www.medscape.com/viewarticle/434192, which is no longer available. It
was a summary of a press release from Reuters, 27 May 2002. -- June 2009.)
"As the Baby Boomers approach 60, there is an increased need to assist newly
diagnosed and advanced disease patients and their families. The number of
men diagnosed with prostate cancer is expected to increase by 40% from
approximately 230,000 to more than 300,000 a year. Over the
next 10 years, the number of prostate cancer deaths could rise from
30,000 to 50,000." (From an USToo email, 30 May 2006)
"Prostate cancer is one of the most common cancers in men. Each year 543,000
new cases are reported worldwide and the disease kills 200,000 mostly older
men in developed countries." (From a Reuters news story, 5 Dec 2006, that had
been located at

but is no longer there as of June 2009.)
"Among men, prostate cancer is the most common cancer (next to skin) and the
second leading cause of cancer-related deaths in men in the United State.
According to the American Cancer Society more than 218,890 men will be
diagnosed with prostate cancer in 2007." (From an email from the National
Prostate Cancer Coalition, 12 March 2007.)
"In 2007, approximately 1 of 6 men in the United States received a diagnosis
of prostate cancer, and 1 in 34 died from it." (From Walsh, et al., NEJM, 357:26, p 2696,
referring to A. Jemal , R. Siegel, E. Ward, T. Murray, J. Xu, M.J. Thun,
Cancer Statistics, 2007, CA Cancer J Clin 2007;57:43-66.)
"In 2007, prostate cancer was diagnosed in an estimated 218,900 men in the

a New York Times article on over diagnosis of prostate cancer, no longer available
on the NYTimes website or in the Internet Archive -- 12 March 2021.)
It was estimated by the American Cancer Society that 192,280 men will be
diagnosed with prostate cancer in 2009 and 27,360 men will die from the
disease." (

In 2010, it was estimated that 217,730 men were diagnosed with prostate cancer
and 32,050 men died of the disease in the U.S. U.S. medical costs linked to
prostate cancer care were estimated at $9.9 billion in 2006. (From
http://www.bloomberg.com/news/2011-05-05/prostate-exam-deaths-tied-to-superbug-ills-spur-cancer-test-inquiries.html
)
It is estimated that in 2011, approximately 240,000 men will be newly
diagnosed with prostate cancer and 33,000 will die of the disease. (From
http://www.nih.gov/news/health/dec2011/od-07.htm)
According to ASCO [the American Society of Clinical Oncology], more than
241,000 men in the United States will be diagnosed with prostate cancer in
2012, and 28,000 men will die from the disease. (From
http://health.msn.com/health-topics/cancer/experimental-drugs-do-battle-against-advanced-prostate-cancer)
The American Cancer Society estmates that in the United States in 2017 there
will be about 161,360 new cases of prostate cancer and about 26,730 deaths
from prostate cancer. (
https://www.cancer.org/cancer/prostate-cancer/about/key-statistics.html)
Compared with previous years' statistics, this seems like a remarkable drop in
occurance and deaths, especially considering the aging population.
Global statistics for prostate cancer incidence and deaths for 2012 (the
latest year for which they have been compiled (noted on 4 Feb 2017)) may
be found at
http://globocan.iarc.fr/old/FactSheets/cancers/prostate-new.asp.
Worldwide, in 2012, there were approximately 1,095,000 new cases and
307,000 deaths from prostate cancer, with the highest incidence (new cases per
100,000 population) being in Australia, follow by North America.

Pre-Detection
In autopsies of men who have died from other causes, both in the United States
and in other countries (e.g., Europe and Japan), microscopic amounts
of prostate cancer are found in frequencies increasing with the deceased's
age, sometimes even in their teens. It seems likely from this that there
are natural processes that lead some prostate cells to undergo a transformation
to a cancerous state and then to lay dormant, neither being killed by the
host's cellular immune system nor moving on to the rapid cell growth
typical of active and of metastatic cancers.
Thus, it is more and more likely, as one ages, that there is a small but
real burden of prostate cancer cells that could become active. The relative
frequency of this being the case seems to vary from society to society,
which informs some of the thinking about the relationship between diet
and nutrition and prostate cancer. For example, the death rates at all ages
of prostate cancer in Japan is much lower than in the United States.
However, it is likely not a genetic difference that is in play here, since
second and subsequent generation Japanese-Americans have substantially similar
incidence rates to Caucasian Americans. That is, acculturation to the typical
U.S. diet or lifestyle (versus the typical traditional Japanese diet)
increases the incidence of active prostate cancer and its resulting death rate.
The questions one must ask are, What causes the cancer to become activated?
How can we reasonably alter lifestyle to decrease our probability of getting
or activating our latent prostate cancer? How can we reasonably alter our
lifestyle to deal with prostate cancer that has already become active?
These issues were discussed briefly in the body of this paper from the
point of view of my personal experience.
In the pre-detection phase, life is normal -- PSA remains in the normal range,
the gland stays a normal size and does not cause urinary problems. The cancer
cells, if any, remain microscopic or as very small inclusions within the gland.
(It should be noted that unlike many other cancers which seem to arise from
a single cell gone awry, prostate cancer, even in its pre-detection phase,
seems to be multi-focal. That is, it arises in a number of locations within
the gland. In that sense, too, it may be thought of as a systemic disease.)
The Possible Role of Infection and Inflammation
I mentioned earlier that I had suspected that an early bout of
prostatitis, when I was in my mid-20's, may have led to a slow cascade of
events which culminated in my prostate cancer. Since prostatitis is
difficult to really eradicate, even with powerful antibiotics, and may
flare up asymptomatically, doing cellular damage repeatedly, it could
well be a culprit. After I wrote that, I came across a press release
from Johns Hopkins University about such a hypothesis published in the
16 September 2002 issue of Nature Genetics. I will quote the release here.
-
BALTIMORE, Sept. 15 (AScribe Newswire) -- Researchers at Johns Hopkins,
Wake Forest, and The National Human Genome Research Institute have
implicated mutations in a "heart disease gene" in hereditary prostate
cancer. The findings, which offer new evidence that at least some cases
of prostate cancer may begin with an infection and inflammatory
response, will be published online September 16, 2002, in Nature
Genetics.
The gene, called macrophage scavenger receptor-1 (MSR1), was identified
more than 20 years ago as a factor in plaque formation in arteries, a
process that contributes to coronary artery disease, or so-called
hardening of the arteries. MSR1 helps immune system cells called
macrophages clean up cellular debris from bacterial infections and
damaged fats or lipids. Macrophage activity has been known to increase
in the early stages of prostate cancer, and the Hopkins investigators
suspected that some MSR1 mutations might inhibit the ability of
macrophages to clean up properly after prostate infections, producing
inflammatory lesions that are often markers of prostate cancer.
This is the first time that MSR1 has been linked to cancer, and it may
tie infections and similar environmental exposures to cancer of the
prostate in a way that we haven't thought about before, says William B.
Isaacs, Ph.D., professor of urology and oncology at the Brady Urological
Institute and Kimmel Cancer Center at Johns Hopkins.
Hunting for gene mutations that increase one's risk for prostate cancer,
researchers screened 159 families with hereditary prostate cancer and
found seven different mutations in the MSR1 gene in 13 families or about
eight percent of the hereditary prostate cancer families studied.
To compare the impact of this gene in men with non-hereditary sporadic
prostate cancer, the researchers screened another 731 men, 365 with
prostate cancer and 366 without. Overall, the research team found that
MSR1 mutations were about seven times more common in men with prostate
cancer than in those without. Mutations were found in 12.5 percent of
African American men with prostate cancer as compared to 1.8 percent
without the disease. In men of European descent, 4.4 percent of men with
prostate cancer and less than one percent without prostate cancer had
MSR1 mutations. "This genetic evidence suggests that MSR1 may play an
important role in prostate cancer susceptibility in both African
American men and men of European descent," says Jianfeng Xu, M.D., Dr.
PH, of the Center for Human Genomics at Wake Forest.
Isaacs and colleagues will conduct additional studies to uncover the
pathway that the MSR1 gene controls and confirm the prevalence of MSR1
mutations in larger studies.
The research was funded by the National Cancer Institute, the Department
of Defense, CaPCURE, Fund for Research and Progress in Urology, and the
William Thomas Gerrard, Mario Anthony Duhon, Jennifer and John Chalsty
Professorship in Urology.

Another web site
(http://www.grouppekurosawa.com/cancer1print.htm) elaborates a bit:
-
Most cancers develop at the site of a chronic inflammation. During an
inflammatory response, damaged cells and invading white blood cells release
a large amount of highly damaging free radicals into the tissues spaces.
These free radicals serve many different functions, including the destruction
of microorganisms. Phagocytic white blood cells, such as neutrophils and
macrophages, are not all that intelligent. They do not know if they are
eating a microorganism or cleaning up debris, such as cigarette tar in the
lungs. The free radicals they release can kill microorganisms in the tissues,
as well as induce substantial tissue damage. If this inflammation becomes
chronic, the free radicals can damage the DNA and repair proteins of cells
resulting in the formation of cancer cells. [1 September 2005]
In March 2006, the possible involvement of a virus in the development of
some prostate cancers was published (Identification of a Novel Gammaretrovirus
in Prostate Tumors of Patients Homozygous for R462Q RNASEL Variant,
Urusman, et al., Public Library of Science, Volume 2, Issue 3, MARCH 2006
http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.0020025)
The study on pomegranate juice (noted above) from
1 July 2006 Clinical Cancer Research has an interesting discussion of the
role of inflammation on oncogenesis. To quote at length again
-
Chief, however, among the potentially explanatory hypotheses is the role of
inflamation in cancer and the antioxidant and anti-inflammatory effects of
pomegranate polyphenols. Chronic inflammation has been linked to the incidence
of many cancers, including that of prostate (37). Studies investigating
samples of human tissues have shown that epithelial cell proliferation
is increased by inflammation (38). An increased risk of cancer is associated
with inflammatory mechanisms, as ~15% of all cancers can be related to chronic
inflammation (38). Epidemiologic studies have found an increased risk for
prostate cancer in men who have a prior history of sexually transmitted
disease or prostatitis (39). Inflammation in the microenvironment of the
prostate cancer cell may stimulate the multistep process of carcinogenesis by
up-regulating the production of pro-inflammatory cytokines and their
signaling pathways. In fact, proliferative inflammatory atrophy has recently
been proposed as a precursor to prostatic intraepithelial neoplasia and
prostate cancer (40).
Inflammation can result in persistent oxidative stress in cancer cells and the
reactive oxygen species may lend cancer cells a survival advantage (41-43).
Mild levels of oxidative stress stimulate cancer cell proliferation (42) and
increase mutation rates through DNA damage and/or epigenetic changes (44).
De Marzo et al. (40) have shown the loss of glutathione S-transferase P1
as an early event in prostate tumors that sets the stage for stimulation of
growth by oxygen radicals. Oxidative stress has also been shown to increase
cancer cell proliferation by increasing the sensitivity of growth factor
receptors and by altering transcription factor activity. Inflammatory cells,
such as macrophages and mast cells, release angiogenic factors and cytokines
like tumor necrosis factor-α, interleukin-1, and vascular endothelial
growth factor, which signal cell growth and proliferation. Additionally,
cytokines regulate signaling pathways that control proliferation, apoptosis,
differentiation, and metastasis....
The role of antioxidants derived from the diet in protection against
oxidative stress and the development or progression of cancer remains a topic
of significant controversy.

A Malignant Flame
Understanding chronic inflammation, which contributes to heart disease,
Alzheimer's and a variety of other ailments, may be a key to unlocking the
mysteries of cancer
By Gary Stix
More than 500 million years ago a set of specialized enzymes and proteins
evolved to defend our primitive ancestors against assaults from the outside
world. If a microbe breached the shell of some Cambrian-era fauna, the members
of this early vintage immune system would stage a savage but coordinated
attack on these interlopers -- punching holes in cell walls, spitting out
chemical toxins or simply swallowing and digesting the enemy whole. Once
the invaders were dispatched, the immune battalion would start to heal
damaged cells, or if the attacked cells were too badly damaged it would
put them to rest....
An article published in April 2014 found another strong link between inflammation
and prostate cancer. It is summarized in
http://www.huffingtonpost.com/2014/04/18/chronic-inflammation-prostate-cancer_n_5175592.html. The original research can be found at
http://cebp.aacrjournals.org/content/23/5/847.abstract?sid=64bedeb2-9a78-4821-949d-34dd00969345.
From the Abstract:-
...Conclusion: Inflammation, most of which was chronic, was common in
benign prostate tissue, and was positively associated with prostate cancer,
especially high grade. The association did not seem to be due to detection bias.
Impact: This study supports an etiologic link between inflammation and
prostate carcinogenesis, and suggests an avenue for prevention by mitigating
intraprostatic inflammation.
Long-term study continues to document pesticide links to illness: Prostate
cancer, lung cancer, diabetes, multiple myleoma, leukemia and other health
effects occur more in people who are exposed to pesticides routinely than
the general population, according to the Agricultural Health Study
(http://aghealth.nci.nih.gov/), a
collaborative effort between the National Cancer Institute (NCI)
(
https://dceg.cancer.gov/research/who-we-study/cohorts/agricultural-health-study
), the
National Institute of Environmental Health Sciences (NIEHS), and U.S. EPA. The
AHS is tracking 90,000 participants over 14 years so far, with another ten
years of expected study. All subjects are certified pesticide applicators
and their spouses who also work on farms. "Those men with a family history
of prostate cancer had increased risk from exposure to Sutan herbicide; the
organophosphate insecticides chlorpyrifos, coumaphos, fonophos, and the
pyrethroid insecticide permethrin for animal uses." For women with a family
history of breast cancer, the scientists found an association with higher
breast cancer rates among those whose husbands used the organophosphate
diazinon. "Paraquat, EPTC (eptam), parathion, malathion, chlorpyrifos,
atrazine and alachlor were [also] associated with wheeze... the sound
produced by narrowed passages deep in the lungs." The study was begun in 1993.

Early Stage
In the early stage of the disease, the blood levels of PSA may rise
asymptomatically (as did mine). Or the cancer may grow, with low PSA,
until it is palpable in a routine DRE or after causing some urinary
difficulties.
In general, at this time, the cancer is still completely contained in the
prostate gland (within the capsule, which is a membrane surrounding the gland)
and is likely not to be too aggressive (say, Gleason score 3+3, which is
what 2/3 of initial diagnoses are, according to my original urologist).
The cancer is still relatively slow growing. One has time to become educated
and make an informed decision about the appropriate course of action. Do not
let anyone (including doctors) push you into doing anything irreversible
before you understand what you are dealing with and what your options truly
are.
Treatment options are discussed in Appendix B.
Post-Treatment Recurrence
In the best of all worlds, after treatment the cancer never recurs and
you eventually recover from any negative effects of the treatment. Or,
like me (so far), you find a way to keep your cancer under control with
non-technological means, and you manage to continue doing so forever.
But that does not happen all the time. Or sometimes, the cancer is detected
after it has escaped the gland. There are second line treatments, also
discussed in Appendix B. These often help for a
significant period of time. (I have met men in my support group who have been
on hormone blockades of one sort or another for over 20 years.)
The likelihood of recurrence is a function of how soon the cancer was detected,
what treatment modality was used, the skill of the practitioner, and luck.
Also is age -- older men (70% of those first diagnosed are over 65 years
old) may well die of something else before their prostate cancer recurs,
which is considered a "cure".
Usually recurrence is detected via periodic PSA blood tests. Less frequently,
PSA stays low but other symptoms indicate the cancer has come back. [Is
this true??] Some of the originally available treatments may be
used for recurrence - radiation and hormone blockade, primarily. Surgery is
possible after radiation (called "salvage surgery"), though many surgeons do
not want to put in the extra effort required, as noted above.
In general, the population of prostate cancer cells needs a form of
testosterone, the male hormone produced 95% in the testes and 5% in the
adrenal glands, in order to live and thrive and grow. This form is
dihydrotestosterone, or DHT, and is produced in the prostate by an
interaction with another hormone, 5-alpha-reductase. What hormone
blockade therapies do is to deprive these cells of
DHT and starve them. There are a number of different ways of doing this.
However, there is often a subpopulation of prostate cancer cells that are
not dependent on DHT for survival. The longer DHT is missing, the more
the sensitive cells will die and a subpopulation that "doesn't care" will
be left and will grow to be the majority population. And there are no
standard and effective treatments for dealing with them that are available
yet. This is one of the reasons for using an intermittant hormone blockade
regimen -- when the cancer has been knocked back "enough", it is given a rest
(along with the rest of your system) so that the androgen-independent cells
remain a minority population. If/when the cancer again recurs, the
hormone blockade approach may well work again.
Metastasis
When the cancer spreads outside the organ of origin and takes root in one or
more other parts of the body, this is called metastasis. In general,
prostate cancer first colonizes the seminal vesicles and the abdominal lymph
nodes, which is why they are removed and biopsied during a radical
prostatectomy. Other common sites are the pelvic bones and the vertebrae
of the lower spine. Later metastases may go to the lungs or brain.
There is no commonly effective treatment for metastatic prostate cancer
except for hormonal blockade although other chemotherapies are used as well,
especially for hormone refractory prostate cancer. Various new therapies
are in development and in clinical trials now, so the situation may
improve in the not too distant future. However, any new drug or treatment
must undergo a significant gauntlet in terms of efficacy and safety testing
in order to achieve FDA approval, so this process of staged trials can go
on for years. One can search for clinical trials
to participate in, if you and your cancer meet certain criteria.
Unfortunately, prostate cancer that has metastasized to the bone is often
quite painful. Combine this with the fact that hormonal blockade often
leads to decalcification of the bones (osteoporosis), which makes them
irreversibly weaker and more subject to fracture, and the situation of
end game is not very pleasant, even with good pain management techniques.
In which we give a brief summary of what medical treatment options there
are, with some pros and cons for each.

- "Watchful Waiting" or Active Surveillance
- Radical Prostatectomy
- External Beam Conformal Radiation (X-Rays)

Caveat
The summaries here have not yet been vetted against the reference books
I read over the last couple of years nor with any MDs. What you get is my
impressions, memories and opinions. Please research anything I say much
further before acting upon it. At some point, I will try to tidy this up.
Also, there has been significant progress in the field since this was
written, especially in terms of diagnostics and chemotherapy/medications,
so do your homework before making an appropriate choice or set of choices.
Nomograms
A nomogram is a chart or table or graph that summarizes complex
statistical data. The Memorial Sloan Kettering Cancer Center provides
prostate cancer nomograms (as well as nomograms for some other types
of cancer) that relate Gleason score, PSA and other factors to probabilities
of survival for various medical treatment options. These may be downloaded
to your computer or used on their web page. Supporting references are also
available at their site
http://www.mskcc.org/nomograms/prostate
Watchful Waiting/Active Surveillance
"Watchful waiting" is a sophisticated form of "doing nothing" and monitoring it.
More recently
it has been referred to as "active surveillance", to imply a less passive
approach. It is often the tack taken for men whose cancer is not very large
or aggressive and who either are in a state of health where many of the
standard medical treatments are not feasible or it is likely they will die
of something else before the prostate cancer will give them symptoms.
Watchful waiting should always be combined with frequent monitoring of the
cancer, usually via PSA testing (most MDs would say every 3-4 months or so)
or some other modality (DRE, TRUS or MRI/MRIS, for example). It should probably
be combined with some of the lifestyle changes also recommended, an increase
in exercise, improvement in nutrition and diet.
With watchful waiting, it is not likely that the cancer will go away. It can
be a time of self-education, a breather between the shock of diagnosis and the
point at which intelligent, informed decisions can be made about the next steps
to be taken in dealing with the condition.
Radical Prostatectomy
A surgical procedure whereby the prostate gland, the seminal vesicles, and
the abdominal lymph nodes are removed. There are three variations on the theme.
In the usual case, incisions are made in the abdomen and the surgeon has a
clear field of view, although the incisions are larger than with the
other two techniques. With this approach,
however, it is sometimes possible to preserve the nerves that run along
the back wall of the prostate and control erectile function (the so-called
"nerve sparing" prostatectomy). The nerves may be spared by a physician of
great skill if the evidence of cancer is not adjacent to the region where
they run.
A relatively new technique is nerve replacement in those cases where the
original nerves need to be removed. Nerves are taken from the ankle and
microsurgically attached after the prostate and the erectile nerves are excised.
This adds about 2 hours to the surgery time and has had some success.
A second approach to removing the prostate is to go in through the perineum,
the area between the scrotum and anus. The incision is smaller, but the
ability of the physician to see is more limited and I do not think that
a nerve sparing approach is taken here.
A third approach is being pioneered at one hospital in Virginia. (I read
about it on the web in Jan 2001, but lost the reference.) They are doing
laparoscopic prostatectomies, going in through a small incision in the
abdomen. They claim some successes, though I do not know much about this.
It is also being done by James Karol, MD at the San Ramon Regional Medical
Center in northern California. Here they use a da Vinci Surgical System,
a computer enhanced surgical system approved by the FDA in July 2000.
(Reference was Associated Press Newswires, 11 May 2001, as paraphrased in
the California Prostate Cancer Coalition News, vol 3, issue 4, July 2001).
The positive things to say about radical prostatectomies are that they often
can remove the entire cancer burden, if caught early enough. The survival
rates of best practice after 10 years is highest for RP. The operation also
makes sense, in my personal opinion, even if the cancer has spread from the
gland, although further treatments are necessary for follow on. The purpose
in this case would be to physically remove as much of the cancer burden as
possible, allowing the subsequent therapies to have a greater chance of
success. My friend, spoken of above, is a case where this approach saved
his life. However, most surgeons will not do this. The protocol is to open
you up and remove the lymph glands and seminal vesicles and send them to a
pathology lab. If the immediate biopsies of these organs indicates that
the cancer has spread from the prostate gland, the surgery is aborted and the
patient sewn back up with his prostate and his cancer.
If you want something different to occur with you in this case, you must be
very clear and very firm with your physician before an operation,
perhaps insist on a written agreement.
The downside of RP is the high rates of impotence and non-trivial rates of
incontinence. Impotence results from nerve removal or nerve damage (as well
as often having a psychological component). Incontinence results from the
nature of the surgery. The urethra is a tube which starts at the bladder,
passes through the prostate and out through the penis. There are two
sphincter muscles controlling the flow of urine - one at the attachment to
the bladder, and one at the place where the urethra passes out of the prostate.
In the surgery, the upper sphincter is removed with the prostate and the
lower surgically reattached to the bladder. So, one has half the muscles
stopping the flow that one had pre-surgery; and the reattachment might not
have the integrity that the original sphincter had.
Walsh and his colleagues note that "other estimates from studies in the
United States have been less promising, with rates of incontinence as high as
74% and rates of impotence as high as 90%. Thus, patients considering
surgery should be referred to surgeons with considerable experience in order
to optimize the likelihood of effective cancer control and to minimize
the likelihood of complications." (See Walsh
article and references therein.)
Even if potency returns, one has no ejaculate. (The bulk of the ejaculatory
fluid is created by the prostate gland and seminal vesicles; when these are
removed, the fluid is no longer present.) However, even if one has erectile
disfunction, the nerves controlling sexual pleasure and arousal are not
affected, so orgasm is possible with an openness to sexual exploration.
External Beam Conformal Radiation
Also called 3D Conformal Radiation, External Beam Modulated Radiation,
and Intensity Modulated Radiation Therapy (IMRT).
This technique uses shaped beams of X-Rays. "Modulation" also implies that
the shape of the beams varies in time as well as in space.
The usual course is 5 days a week for about 8 weeks, where each
X-Ray session lasts about 20 minutes, more or less. The idea is to deposit
enough X-Ray energy into the prostate to kill the cancer (and healthy) cells
there, while doing as little damage to surrounding tissue, urethra
and rectum as possible.
Often, a man will be put on 3 months of hormone blockade therapy before
undergoing X radiation. This is done in order to shrink the size of the
prostate and weaken the cancer, both of which allow this technique to be more
effective. (This is known as neo-adjuvant hormonal blockade.)
X-Rays (basically very high energy photons or light waves) start depositing
their energy as soon as they encounter matter. In this case, the matter is
the patient's flesh. If too much energy is deposited outside the prostate
there will be severe side effects. So the technology uses a number of external
beams conformed to the patient's physiology. Each beam alone is too weak to
do much damage to the tissue it goes through. But when they all meet at the
prostate, their combined energy in the gland is supposed to be high enough
to be effective there in causing cellular damage and death.
The software and hardware for designing and shaping the beams is constantly
improving, as are the imaging techniques used to inform this software.
Survival rates for best practice out to about 10 years are comparable with
best practice radical prostatectomy, but after 10 years fall off in
comparison. (These are age-adjusted survival rates; that is, all other things
being equal.) Other positives are that this technique is not as traumatic
as surgery and can be done again if cancer recurs.
The X radiation damages the tissue it passes through. It makes it tougher,
among other things. Most surgeons will refuse to do a radical prostatectomy
on a patient who has had external beam radiation because the job of
cutting through the tissues and removing the prostate is a little more
difficult and time consuming than if radiation had not been used. There
are, however, surgeons willing to do such "salvage surgery" if indicated
(that is, if, after radiation, localized prostate cancer returns).
The side effects during radiation treatment are usually fatigue and often
bowel problems. The lower bowel passes right behind the prostate and is
naturally subject to significant radiation. Also, since intestinal cells
are naturally very rapidly dividing, the radiation will do more damage to their
DNA than to that of more quiescent cells.
Longer term side effects do include damage to the rectal wall, incontinence
and impotence. These latter two effects often come on slowly, say over the
course of a year after treatment. In best practice they are comparable
to the rates quoted for radical prostatectomy. (These rates of side effects
seem to be somehat higher if patients are asked rather than their doctors.
Also, the answers do depend quite sensitively on how the questions are
posed and the degrees of effect that can be described. But this is true
for all side effects of all the treatments discussed here, and, I would
venture, all other medical interventions.)
Walsh and his colleagues note that "Dose-escalated radiation with the use
of conformal techniques causes intermittent rectal bleeding of grade 2 or
higher (requiring transfusions, interventional radiology, or endoscopic or
operative intervention) in 1.5 to 18% of patients and causes impotence in 40 to
60% of patients." (See Walsh article
and references therein.)
Brachytherapy (Seed Implants)
Radiation can be delivered to the prostate gland locally, with less probability
of damage to external tissue, the theory goes, if a radioactive substance
is emplanted within the prostate. In brachytherapy, that is exactly what is
done.
There are two flavors of this treatment. In one, the radioactive substance is
put into the prostate gland in carefully controlled locations for carefully
controlled amounts of time. This uses high powered radioactive materials (I
don't recall which isotopes) and was the form that Andy Grove had done (see
the article in the references, above).
In the other approach, the radioactive material is permanently emplanted
in the prostate. One substance used has a half-life of about 3 months; the
other has a half-life of about 18 months.
In all cases, the radioactive material is encased in rice-grain sized
metal (titanium) pellets. The emplantation is done using trans-rectal
ultrasound
imaging to guide the placement of the pellets; and the planning is done
beforehand using the various available imaging techniques. The idea is to
spread the placement of the seeds throughout the gland, but not too close
to the urethra, its sphincters, the nerve bundles running along the back
side of the prostate which control erections, or the rectal wall, to
minimize damage to those structures. The point of entry is again the
perineal region between the anus and the scrotum, with long hollow tubes
used to guide the placement.
Iodine-125 is one isotope used. It has a half-life of 59.4 days, with
predominant decay energies at 27 and 35 kev. In a titanium seed, there
is also a peak about 22 kev. These energies imply that the radiation is
most intensive within millimeters.
Another isotope used is Palladium-103, with a half-life of 17 days. It has
predominant peaks at 20 and 22 kev, so also deposit energy within millimeters
of the seed.
Other isotopes are also used.
Both types of brachytherapy can be done with local anesthetic on an outpatient
basis, so are far less traumatic than surgery and far less time consuming than
Three-D Conformal Radiation. Survival rates for best practice are probably
comparable to external X-Rays out to 5 years (but I do not have any of the
statistics and that last statement is just a guess for now).
Brachytherapy may be done in conjunction with hormonal blockade (beforehand, to
shrink the gland and kill off some of the cancer), or with external beam
X-radiation (afterward, to enhance the effects).
Side effects also include impotence and incontinence as well as bowel upset
and sometimes bowel damage.
In my opinion, follow on imaging with MRI/MRIS after, say 1 year, would allow
the effectiveness of the treatment to be assessed. Any remaining cancer
metabolism would indicate that additional seeds are needed and that the
original placement did not fully cover the appropriate parts of the gland.
Another approach to brachytherapy is to do real-time planning. This involves
pre-operative MRI, perhaps CT scans and prostascint scans which are
combined (via software and hardware) with high resolution ulltrasound
images minutes before and during the seed implantation procedures. The
software determines the best location for each seed, based on the gland
location and geometry and based on image analysis of the cancer's
locations. Each seed is monitored and deviations from a planned location
lead to immediate modifications in the planned locations of seeds not
yet implanted. This prevents both cold spots and hot spots, locations
which would receive too little or too much radiation. Such dyanmic
adjustment can decrease the incidence of side effects, such as impotence,
incontinence and rectal wall damage. Not all practitioners follow this
approach yet.
Proton Beams
Protons are the heavy charged particles in atomic nuclei and may also be used
to deposit energy into the prostate with the goal of destroying the cells
there, both malignant and healthy. Proton beam therapy was pioneered at Loma
Linda University in southern California and is also being investigated at
Harvard University, in Cambridge, Massachusetts. The
Loma Linda web site is given in the Bibliography, above.
Particle beams behave differently than X-Rays, which is the attractive feature
of this technique. The goal of both is to deposit enough energy in the target
cells that their DNA is broken and their metabolic processes are interfered
with, leading to cell death. X-Rays, as noted above, start depositing their
energy as soon as they encounter matter, such as the patient's flesh and organs
outside the prostate, on their way to the prostate. That is why using many
simultaneous low power beams from many directions, and shaping each quite
precisely is important in trying to minimize collateral damage.
Protons go right through matter until a certain depth, at which they deposit
all their energy. This depth can be tuned by carefully calculating the
matter the beam will go through (by imaging and computer modelling) and then
precisely tuning the beam's energy. In this way, much less collateral
damage may be done. The process is designed to be more efficient than X-Rays
in that regard.
Still, one needs to undergo a series of treatments for some weeks, meaning
that one needs to be able to spend that time at Loma Linda. In addition,
Three-Dimensional Conformal X-Radiation is often used in conjunction with
proton beam therapy, though obviously less than when it is used alone.
Because the technique is relatively new, I don't believe the survival
statistics go out beyond 5 years or so.
A web site for men who have undergone proton beam therapy, and with a great
deal of information about that technology, is the Brotherhood of the Balloon,
http://www.protonbob.com/
A summary of the state of proton beam therapy as of 26 March 2012 may be
found at
http://www.businessweek.com/news/2012-03-26/prostate-cancer-therapy-too-good-to-be-true-explodes-health-cost.
There are around 10 centers providing this therapy in the U.S., with more being
built. The cost is greater than that of standard X-ray treatments, but the
article questions whether or not the side effects of treatment are less than
those of other medical therapies.
Cryotherapy
The idea here is to use extreme cold (liquid nitogren) to kill off the
prostate cells, especially the cancer cells, without damaging other areas
of the anatomy. This is done by inserting tubes through the perineum into the
prostate, as guided by trans-rectal ultrasound. These tubes are insulated in
the areas outside the prostate. Also, a heating catheter is inserted into
the urethra and up to the bladder to prevent damage to these structures.
Liquid nitrogen is introduced into the cooling tubes for enough time to freeze
the areas that are desired to be killed. I believe this can be done on an
outpatient basis, much like brachytherapy.
The positives of this technique are its ease (vis-a-vis surgery and
radiation therapies). Best practice is said to give comparable survival
rates out to 5 years [I think - check this out later]. Side effects
include damage to areas not intended for treatment, and include impotence,
incontinence and bowel damage, with the resulting infections.
I don't think that cryotherapy has been around long enough for 10 year
survival statistics to be available.
Ultrasound/thermal therapy/Hyperthermia
I don't know much about this. I think another technique that may be used
to kill prostate cancer tissue is localized tissue heating via the application
of ultrasound, microwaves, or radiofrequency radiation. I don't know how
effective this is, survival statistics, what damage there is to surrounding
tissue both because of energy deposition from the source and from heat
transfer from the affected tissue.
Side effects would come about from damage to surrounding tissue - incontinence,
impotence, bowel damage are the possibilities.
Hormonal Blockade
As discussed above, prostate cells and prostate cancer cells need the
male hormone dihydrotestosterone (DHT) to function and survive, for the most
part. DHT is produced in the prostate by the action of an enzyme
(5-alpha reductase) on the hormone testosterone. Ninety five percent of
the body's testosterone is produced in the testes; 5% comes from the adrenal
glands.
In order to starve the prostate cancer cells, one wishes to deprive them
of the DHT they need. This can be done in a number of ways, since there
are a variety of pathways in the body to the production of DHT.
- Block the production of lutinizing hormone releasing hormone (LHRH)
in the pituitary. This is the initial hormone in the cascade
that leads to testicular production of testosterone.
- Block the production of testosterone by the adrenal glands.
- Block the conversion of testosterone into DHT.
- Block the action of the testosterone with an estrogenergic compound
such as diethylstilbesterol (spelling?) (DES).
- what else??
Any one or a combination of these actions serves to blockade some or all
of the DHT. Different drugs are used for each step.
Common side effects of hormonal therapy are
- breast swelling and tenderness
- hot flashes
- loss of libido
- bone loss/osteoporosis
but these are reversible when the treatment is discontinued.
If hormonal blockade is used too long, the prostate cancer cells that are
sensitive to the lack of DHT die off sometimes leaving behind a small
subpopulation that can live and grow independent of the presence or
absence of DHT. These are called hormone refractory cells and a recurrence
of the cancer due to these cells is known as hormone refractory prostate
cancer. It is a form of the disease for which hormonal blockade, in any
of its manifestations, does not work.
Thus, a standard protocol for hormonal blockade therapy is to be on it for
about a year (or until the PSA falls below some standard value, nominally
0.01 ng/ml) and then to go off of treatment until it rises to some nominal
value (say 1.0 or 2.0 ng/ml), cycling through on and off periods. The logic
of the off period is to both allow your body to recuperate from the effects
of the hormonal blockade and to allow any hormone-dependent prostate cancer
cells to become the dominant population. Too long on blockade and any
refractory cells may become the dominant population.
Hormonal blockade may also be used as a preliminary therapy, before surgery
or radiation, to weaken and shrink the cancer and make it more amenable to
the other treatments. It is also a therapy of last resort, after surgery
and/or radiation have been ineffective in eradicating the cancer and it has
metastasized. In this case, it buys time and some quality of life, but
generally does not "cure" the cancer or keep it in check forever.
Further, for men with large glands, whether due to BPH or normal aging, a
course of hormonal blockade is usually required before other treatments
in order to shrink the physical size of the gland and allow subsequent
treatments to be more effective. This is known as neo-adjuvant hormonal
therapy.
The standard agents of hormonal blockade are
- Lupron (leuprolide acetate) - LHRH inhibitor, acts on pituitary gland
to block
production of hormones that eventually lead to testosterone
production by testes. Available as an injection, either every 1,
3, or 4 months.
- Eulexin (flutamide) - an anti-androgen (two capsules orally every
8 hours)
- Proscar (finasteride) - a 5-alpha reductase inhibitor; blocks
transformation of testosterone to dihydrotestosterone (DHT) -
oral administration (what frequency?)
- Zolodex (goserelin acetate) - another LHRH inhibitor - one injection
every 4 or 12 weeks
- Casodex (bicalutamide) - blocks testosterone production in the adrenal
gland - one pill a day
- Nilandron
Nilandron(R) (nilutamide)is a hormonal therapy that blocks the
production of testosterone and is used to increase survival time
and promote disease regression in men with advanced prostate cancer.
...
Nilandron(R) is a nonsteroidal anti-androgen indicated for use in
combination with surgical castration for the treatment of men with
metastatic prostate cancer. Nilandron(R) binds strongly with androgen
receptors and prevents the normal androgenic response, resulting in
complete peripheral anti-androgenic activity when combined with
surgical castration. Results of well-controlled clinical trials have
demonstrated that Nilandron(R) in combination with surgical castration
increases survival time and relieves metastatic bone pain.

If Lupron is given with no other treatments, a situation known as PSA
flare occurs which can be quite dangerous. For the first week or so after
the injection, one's PSA levels rise dramatically and the prostate cancer
cells seem to have greater activity. In some men, this has led to the
formation of metastases where there were none previously or to a sudden
exacerbation of symptoms. Flare may be avoided by simply preceding the
administration of the Lupron by a week or so of Casodex.

may, however, promote the production of a molecule, Nestin, which promotes

APPENDIX C: Future Therapies
In which a brief listing of possibilities is given with some references
for each.
The simple message here is that there are many avenues under investigation
for controling or curing prostate cancer, many more than I've listed below.
Not all will be effective, in the end of clinical trials, but there is
no doubt that some will be. In two years or five years or ten years.
If one can control one's cancer by mean of some non-irreversible
treatment for however long it takes for these future therapies to come
to market, then cancer will be a chronic disease or one that is indeed
eradicable. My dietary approach, with mother's milk, has been quite successful
for me. It is up to each man, in consultation with his trusted and
knowledgeable advisors, to decide which approach is most appropriate
for him, given what he knows about his particular disease, his health
in general, and a whole panoply of philosophical and quality of life issues.
But here there lies even more hope for the future, if we can get from here
to there.

http://www.oncolyticsbiotech.com/
Oncolytics Biotech, a Canadian company, is beginning a Phase I study
of a reovirus (Reolysin) after successful in vitro and
animal studies.
Cancer cells are often able to 'hide' from the immune system.
However, certain type of cancers have a weakness in their cellular
armor: an 'activated' Ras pathway, a sort of genetic soft spot found
in perhaps more than two-thirds of all latent and actual tumors.
Happily, healthy cells don't have this 'oncogene' or 'cancer
gene' in their makeup. However, the Ras-activated cells are unable
to manufacture the cellular protein PKR. In healthy normal cells,
PKR prevents reoviruses from replicating. In Ras cells, this
protection doesn't exist. Which means the reovirus can slip aboard,
multiply and burst the infected cancer cell from within. Kill the
killer.
"The big bonus is that the 'infection' is a true one; the reovirus
spreads from cancer cell to cancer cell, clearing away the invader
but leaving normal cells alone. This cycle of infection, replication
and cell death is believed to roll on until there are no more
'victims' - cancer cells unwittingly burdened with an activated Ras
pathway - left to kill."

Hybrid Molecule Causes Cancer Cells To Self-Destruct (4 Jan 2007)
Johns Hopkins researchers, led by Kevin Yarema, have combined
butyrate with a sugar, N-acetyl-D-mannosamine (ManNAc), to enhance
the anti-cancer properties of each molecule. Once inside the cancer
cell, the molecules separate. The ManNAc is processed into sialic
acid, which "plays key roles in cancer biology, while butyrate
orchestrates the expression of genes responsible for halting the
uncontrolled growth of cancer cells." The two molecules seem to have
a synergistic effect on apoptosis of cancer cells, better than either
alone or the two administered separately. The researchers believe this
compound has minimal effect on healthy cells. This work has all been done
in vitro and has so far focussed on the molecular mechanisms of
the apoptotic effects.

stopping the growth of new blood vessels to feed a cancer,
antivascular therapies temporarily close off existing blood vessels

not so long as to damage healthy tissue. Companies working in this
area are Oxigene, Aventis and AstraZeneca.

From a press release (14 May 2002): "...announced the publication of

These preclinical studies demonstrated potential for use of AVI's
third-generation antisense drug platform, NEUGENE(R), in treating
prostate cancer and viral infections caused by the
Caliciviridae, a
family of RNA viruses. 'AVI continues to build strong scientific
support for its antisense technology,' said Patrick L. Iversen,
Ph.D., AVI's senior vice president of research and development.
'These studies confirm our belief that NEUGENE compounds are
capable of addressing a broad range of health problems for which
there are no known cures.' Antisense as a Treatment for Prostate
Cancer[:] Prostate cancer is the most frequently diagnosed malignancy
and is the most common cause of mortality among men. In 'Prostate
cancer: Status of current treatments and emerging antisense-based
therapies,' Gayathri Devi, Ph.D., senior scientist at AVI, compared
current prostate cancer treatment strategies with preclinical and
clinical prostate cancer antisense studies conducted in the past
year. Dr. Devi reviewed stages and treatment options for prostate
cancer, which were linked to the antisense approach. Her research
showed that AVI's antisense technology is an attractive alternative
to traditional cancer therapies."

In Phase 1 for HRPC, phase 2 for PCa (July 2002 web page); by 2009,
had been in a Phase 3 HRPC study.
"Satraplatin (BMS-182751 or JM-216) or bis (acetato) ammine dichloro
(cyclohexylamine) platinum is a member of a novel class of platinum (IV)
compounds developed by Johnson Matthey which are absorbed by the oral
route. In preclinical studies, Satraplatin had shown cytotoxic and
antitumor activities that are comparable to that of cisplatin or
carboplatin."
"Clinical studies were conducted and had shown activity on platinum
sensitive tumors, small cell lung cancer, and ovarian cancer. It has
also shown activity in hormone-refractory prostate cancer. Dose-limiting
toxicities are myelosuppression (neutropenia and thrombocytopenia) and
gastrointestinal toxicity (diarrhea)."
"NeoOncoRx will explore this drug for prostate cancer. Prostate cancer is
now the second leading cause of cancer death in men. It is estimated
that in 2001, approximately 198,100 new cases and 31,500 prostate
cancer-related deaths will occur in the United States. Treatment in
prostate cancer provides prolonged disease-free survival for many with
localized disease, but is rarely curative on patients with locally
extensive tumor. Metastatic tumor is currently not curable. A continuing
unmet medical need for new effective drugs still exist."
"The advantages expected from this novel oral platinum compound rely upon
its oral route of administration. These include patient convenience and
health cost containment, meaning outpatient therapy."

The dose-limiting toxicity of chemotherapeutics, heterogeneity and
drug resistance of cancer cells, and difficulties of targeted delivery
to tumors all pose daunting challenges to effective cancer therapy.
We report that small interfering RNA (siRNA) duplexes readily
penetrate intact bacterially derived minicells previously shown to
cause tumor stabilization and regression when packaged with
chemotherapeutics. When targeted via antibodies to tumor-cell-surface
receptors, minicells can specifically and sequentially deliver to
tumor xenografts first siRNAs or short hairpin RNA (shRNA)–encoding
plasmids to compromise drug resistance by knocking down a multidrug
resistance protein. Subsequent administration of targeted minicells
containing cytotoxic drugs eliminate formerly drug-resistant tumors.
The two waves of treatment, involving minicells loaded with both
types of payload, enable complete survival without toxicity in mice
with tumor xenografts, while involving several thousandfold less drug,
siRNA and antibody than needed for conventional systemic
administration of cancer therapies.

- Targeting Prostate Specific Membrane Antigen -- Immunotherapy
(From a news release 4/24/2006): Progenics Pharmaceuticals has acquired
complete control of PSMA Development by buying Cytogen's 50 percent
interest.... The venture has been developing in vivo cancer
immunotherapies based on prostate-specific membrane antigen. PSMA is
a protein primarily found on the surface of prostate cancer cells and new
blood vessels associated with other solid tumors. Targeting PSMA offers
the potential for highly specific cancer therapy.
"Having acquired all rights to in vivo PSMA immunotherapies, we now plan to
develop them fully," said Paul J. Maddon, Progenics' founder and CEO.
"Prostate cancer patients with metastatic disease have the greatest unmet
medical need, and we intend to initiate phase 1 clinical studies in this
setting in 2007 with our PSMA ADC. Progenics has core research and
development, manufacturing, clinical, and regulatory teams in place and
plans to leverage them to expedite PSMA-based drug development."

This is a press release from 7 April 2009.
Medivation was acquired in August 2016 by Pfizer, after the FDA approved
(in 2012) its drug XTANDI (enzalutamide) capsules for the treatment of
patients with metastatic castration-resistant prostate cancer who have
previously received docetaxel. XTANDI is an oral, once-daily androgen
receptor inhibitor.

2009 [DOI: 10.1126/science.1168175] (in Science Express Reports)
This is a press release from Medivation (7 April 2009) and the Science
news coverage and on-line prepublication article.
A new drug by Medivation, Inc. offers a radically different way of
attacking prostate cancer, showing promising results in an initial trial
and is set for larger-scale testing. A study report in the journal Science
looked at this drug, MDV3100, and its ability to block the receptors for
androgens which drive tumor growth on cells. After treatment with the drug,
there were "sustained declines" in PSA levels in 43 percent of the
participants, which the report called a "promising" result. The
researchers now have data on 114 men given the drug.
"It showed not only declines in PSA but also regression of the tumor on
scans and also that circulating tumor cell counts, another measure of
treatment, converted from unfavorable to favorable in a considerable
percentage of patients," said Dr. Howard I. Scher, chief of the
genitourinary oncology service at Memorial Sloan-Kettering Cancer Center
in New York City and co-author of the study.
Based on those results, an application for a large-scale trial has been
submitted to the U.S. Food and Drug Administration.
- PARP Inhibitors
"Most cancer treatments work by blasting DNA with chemotherapy or
radiation. Cancer can fight back by using PARP enzymes to fix damaged
strands of DNA. The new medicines are designed to block the enzymes and
kill the cancer." (From a Bloomberg news article, 31 May 2009, URL not
available)
"A parp also known as a Poly (ADP-ribose) polymerase is an enzyme
which repairs damage done to our DNA. In basic terms a parp enzyme
regulates our body repairing damaged DNA. In normal cells this is
useful and stops cell death however Doctor de Bono and his colleagues
have suggested that cancer cells may used the PARP repair method to
their advantage.
A parp-1 inhibitor is a new drug which causes inhibition of parp
function. Studies recently conducted have shown that this new parp
drug is an inhibitor of cancer as it disrupts the chemotherapy
resistance in cancer cells." (From

- Access to Unapproved Drugs (FDA regulations)
http://www.fda.gov/Drugs/default.htm
From this page, contact info is available or one can do a search.
The previous set of regulations is now difficult (impossible?) to
find, as of June 2009.
Outlook
"The Pharmaceutical Research & Manufacturers Association calculates that
there are currently 170 U.S. drug and biotech companies developing more than
400 potential new compounds to fight cancer, roughly double the number of just
six years ago. Indeed, so many new drugs are in the works that clinical
researchers are swamped, and cancer experts note that crucial human trials
have been delayed due to lack of volunteers." - From Barrons,
~18 May 2001.
