Back in
1990, when a suspicious lump was discovered on my prostate, my ignorance of the
prostate gland and the possibility of prostate cancer was monumental. No one in
my family or even among my close friends had ever had prostate cancer, and it
never occurred to me that I might one day have the disease.
Now, 25years later I am still alive, the average man over 50 is more aware of prostate
cancer, and also many less toxic and more effective treatment options are
available. And yet one thing has not changed: just hearing the doctor say, “I’m
afraid it’s cancer,” can leave even the most pragmatic man planning the music
for his funeral.
Truth is there is still a lot of misinformation and
misunderstanding out there about this disease. So here are some facts that I
hope will alleviate some of your fears, and also clarify why I still contend
that if you have to have cancer, prostate cancer is the best deal in town.
Prostate
cancer is unique among cancers because the mortality rate is so low. According
to the American Cancer Society, more than 2 million men who have been
diagnosed at some point are living with the disease in the U.S. It’s difficult
to determine actual prostate cancer survival rates because most men are around
70 years old when diagnosed, and many of them will die from medical problems
unrelated to the disease. But if you check out the “relative” 5-year survival
rate of all stages of prostate
cancer, you will find it is almost 100%. And that almost 100% of men with low-risk or intermediate-risk disease live more than 10 years after
diagnosis.
Why is
it that the statistics for prostate cancer are so much less frightening than
for other cancers?
1) The
PSA test is an early warning system that other cancers don’t have.
2) It
can easily be diagnosed at an early stage.
3) In
most cases it has an exceptionally slow growth rate.
4) Extremely
effective monitoring and treatment is now available.
5) It
has a pattern of spread that spares critical organs like the brain, lungs and
liver.
6)
There is a safety net like no other called “hormone blockade” that induces
remissions lasting more than 10 years in men with relapsed disease after
surgery or radiation.
So instead of thinking about your funeral, what you really
want to be focusing on is not rushing into some form of radical treatment that
will virtually guarantee some degree of
impotence or incontinence.
It appears that patients and doctors alike
struggle with the idea of “watching” anything called cancer. But unless you
have the less common high-risk form
of the disease, my advice to you is to consider “Active Surveillance” really
carefully, especially if you are over 70. Because bottom line—and it bears
repeating—out of over 200,000 men in the U.S. diagnosed annually with prostate
cancer, the overwhelming majority will die with the disease, and not from it.
MARK SCHOLZ, MD
Being medical oncologists rather than
surgeons—and being more impressed by the toxicity of surgery than by its
effectiveness—my partners and I hypothesized back in the early 1990s that since
testosterone inactivating pharmaceuticals (TIP) are powerful enough to reverse
metastatic disease, they should be even more effective against early-stage
disease.
Clinical
Experience with TIP for Early Stage
In 2011, we published a scientific article in the Clinical Genitourinary Cancer
detailing the twelve-year outcome for 73 men who embarked on TIP as primary
therapy. In this group of men the average PSA was 9 and the average Gleason
score was 7 (intermediate grade). Most of the men had tumors in their prostate
large enough to be felt by digital rectal examination. Twenty-one of them maintained a low PSA indefinitely with a
single course of TIP—they never needed a
second cycle.
Another group of 24 men required periodic
repeat cycles of TIP to keep their PSA less than five. In the remaining 28 men,
after one or more cycles of TIP, the decision was made to undergo treatment
with surgery, seeds or radiation. However, the average time to treatment was
6.2 years after the first cycle of TIP. Only three of those 28 men ever
relapsed after treatment. In summary, this study showed that initial remissions
with TIP were universal and that even if the remission was not permanent,
treatment with more radical therapy was delayed many years.
In 2012, we published another scientific
study in The Prostate, in which we
evaluated the effect of 12 months of TIP in 102 men. Twenty-two men were in the Low-Risk category, 30 were Intermediate-Risk and 50 were High-Risk. The median PSA was 7.8 and
the median Gleason score was 3 + 4 = 7. The attainment of a clear biopsy after
TIP followed by a sustained 7- year remission occurred in forty-five men. The
likelihood of durable remission was dependent on the risk category: 82% of Low-Risk, 47% of Intermediate-Risk and 25% of men with High-Risk required no further treatment.
Monitoring
TIP’s Effectiveness
One of the beauties of TIP is how easily
its anti-cancer effects can be monitored with PSA. Although there is much
debate about using PSA for cancer
screening, PSA is an amazingly accurate tool for monitoring treatment response. In a study we published in Urology in 2007, we showed that more
than 95% of men with newly-diagnosed disease drop their PSA to less than 0.05
within eight months of starting therapy. It’s a rare for cancers to continue producing
PSAs above
a threshold of 0.05 after six months of TIP therapy. However, when these rare cancers occur, i.e.
when an elevated PSA nadir occurs, it is a flashing sign that aggressive multi-modality
therapy should be instituted.
What about Side
Effects?
So
what is the catch? To this point TIP
sounds like a very logical way to initiate treatment. Even if the disease is
not arrested altogether, it delays progression for many years. And men who
select TIP as initial therapy can always “jump ship” and undergo radiation or
surgery. Delaying surgery or radiation with their potentially irreversible side
effects makes sense considering the acclerating pace of medical progress. In this
rapidly changing environment, postponing irreversible treatment for even five
years is unquestionably an attractive proposition.
The
catch is that while TIP side-effects are manageable, they are not trivial.
Without attention to diet, notable weight gain occurs. Without regular
resistance training and weight lifting, significant muscle weakness will ensue.
While on treatment, the majority men lose their sex drive. A loss of sex drive
is, however, different than impotence. With medications such as Viagra and
Cialis most men on TIP can have erections sufficient for intercourse. Sex can
be enjoyed, but it is not sought after with the usual male verve. There is also
the potential for additional side effects such as breast enlargement,
osteoporosis and hot flashes. As dire as these sound, they are preventable with
common medications such as Femara, Prolia and progesterone. However, the side
effects are cumulative and become more prominent the longer TIP treatment is
continued.
Final Thoughts
Some
men are concerned that their cancer
will progress if “real treatment” like surgery or radiation is delayed. They
forget that surgery and radiation only eradicate the “friendly types” of
prostate cancer, the ones that remain contained in the gland. The real danger
lies in the possibility of microscopic metastasis. Radiation and surgery have
no effect whatsoever on cancer that has already spread. Only TIP circulates
throughout the entire body attacking early-stage micro-metastasis in the lymph
nodes or bones.
In
my next blog, I will be discussing a new, more powerful type of TIP that has
recently been approved by the FDA. The enhanced effectiveness of this new drug
may enable a shorter course of treatment. And since testosterone levels in the
blood remain normal throughout, the risk of lingering side effects should be
eliminated.
