Ralph H. Blum (1932-2016)


Many of you may have noticed that the Prostate Snatcher’s Blog has been temporarily on hold.  Ralph Blum, my coauthor of the Blog, passed away in March at the age of 84.  Ralph underwent surgery for a non-prostate-cancer-related abdominal problem and unfortunately was never able to recover.

This has been a sad time for me.  In fact, I needed the last couple months to get my emotions settled down before restarting the Blog.  Ralph called himself a “Refusenik” due to his strident stand against unnecessary treatment for prostate cancer.  Refusenik is a Russian term that describes individuals who fight the establishment.  Ralph was certainly a prostate cancer Refusenik. Ralph didn’t only talk the talk; he walked the walk.  By the time I first met him, he had already been monitoring his untreated prostate cancer for 11 years with PSA testing and an early type of prostate MRI scan technology.  At our first visit in 2001, he flew in from Maui for consultation about beginning some form of treatment since his PSA had risen up to 18. After extensive discussions that went on for more than a year, he reluctantly decided to begin Lupron hormone therapy for 12 months.  That turned out to be an effective solution, stabilizing his disease for another 12 years.  In 2013, his PSA started rising again and he decided to undergo radiation, which he tolerated without difficulty. The story of Ralph’s journey through all the many mainstream and alternative treatment options is told in the book we wrote in 2010 and continued on the Blog.

Ralph and I spent many hours together working on the book project and writing our weekly Blog. The book writing process, due to my feeble writing skills included writing lessons for me.  He taught me the writing craft from the ground up.  He was a generally patient and apt teacher though we occasionally had some volcanic conflicts.  It was no surprise, considering how many hundreds of hours we spent together and that we are both opinionated.

Ralph led an extremely interesting life but he was never particularly talkative about himself. Most of our conversations were about the business at hand, our various writing projects. Too bad, because I think he could have shared many lively stories. Just to give you an example, one day I was talking with him about my deep and abiding respect for Winston Churchill.  He passingly let drop that he ate dinner with Churchill at his home in Chartwell!  At first I was disbelieving, but it turned out that Ralph was dating his daughter, and the old man wanted to know who she was seeing so he invited Ralph over for dinner for an inspection.  Ralph didn’t have any profound recollections about the experience except that Churchill was surprisingly short in stature.  I occasionally tried to plumb Ralph for more stories about his life, but he had very little interest in talking about himself.  I did learn, however, that his mother was a silent film star named Carmel Myers. Ralph once showed me a picture of his mother who was indeed quite a beauty.  She was so attractive in fact that Charlie Chaplin, who was also in the picture, was lustfully leering at her.

Ralph was trained by Margaret Mead as a cultural anthropologist. He also worked with Timothy Leary doing early research into LSD at Harvard.  He spent time in Italy as a Fulbright Scholar.  He received grants from the National Science Foundation and the Ford Foundation, and received a BA in Russian Studies and Anthropology.  Somewhere along the way Ralph learned to speak French (he lived in Paris for a time).  Besides also speaking Russian, I don’t know if he spoke any other languages.

After Ralph graduated Phi Beta Kappa from Harvard he traveled to Soviet Russia and wrote cultural reports published in The New Yorker between 1961 and 1965.  He also studied Soviet Cinema at Leningrad University.  He wrote for Readers Digest, Cosmopolitan, Vogue and Saturday Evening Post. He published three novels: The Foreigner (1961), The Simultaneous Man (1970) and Old Glory and the Real-Time Freaks (1972).  Both The Simultaneous Man and Old Glory reflect his involvement in early drug research.  He also won the 2011 Gold Medal from Nautilus Book in Wellness, Prevention and Vitality for Investigative Reporting in Invasion of the Prostate Snatchers.

Ralph was a special and totally unique person.  He and I were a rather unlikely match considering his generally bohemian lifestyle compared to my rather straight-laced, workaholic ways.  Even so, our differences had a counterbalancing, net-positive effect.  I am very grateful that Ralph approached me with the idea to write a book back in 2007.  He came up with its uniquely memorable title.  And while the book has no doubt benefited many people, Ralph benefited me personally in a remarkable way.  Without his mentoring I would still be the literary neophyte he approached back in 2007.  Instead, under his influence, he transformed me into a passable writer. Winston Churchill said, "We make a living by what we get, but we make a life by what we give." Ralph, thank you for everything you gave us.

Distinguishing aggressive disease from slow-growing tumors means more patients can forgo treatment.  
Several new prostate-cancer tests aim to reduce needless biopsies and unnecessary treatments by sorting out harmless from aggressive tumors. 30 MILLION U.S. men will have a PSA test. 6 MILLION of them will be found to have elevated PSA levels.  1 MILLION of them will undergo a prostate biopsy.  180,000 men who have biopsies will be diagnosed with prostate cancer. Another 180,000 men will have prostate cancer the biopsy missed.100,000 men with prostate cancer will have low-risk tumors that are unlikely to spread or cause symptoms.  60,000 men with low-risk cancers will undergo surgery or radiation anyway, probably unnecessarily.

Mark Scholz, a prostate oncology specialist in Marina del Rey, Calif., maintains that an mpMRI can yield much of the same information as a biopsy and far less invasively. Low-risk prostate cancers barely register, he says, adding, “When patients find out they have a choice between 12 harpoon sticks to the prostate through the rectum or an MRI, they are on board big time.” 

Joel Copeland, 62 years old, has been monitoring his PSA closely for a decade; his two brothers were diagnosed with prostate cancer. He opted for an MRI instead of a biopsy when his PSA bounced up in 2013. “I don’t like needles, but that’s not the point,” Mr. Copeland says. “The point is, biopsies can cause infection and miss cancers.”

Testosterone Replacement Therapy (TRT)


Testosterone (T) preparations have been available for more than 70 years.  In 2013, over 2.2 million Americans were prescribed testosterone.  Interestingly enough, about 1 in 4 men prescribed testosterone do not have a baseline testosterone level drawn as primary care physicians may write the prescription without ordering a blood test first.  In a study of 63,000 men from the Truven Health Marketscan Commercial and Medicare Supplemental Insurance database between 2010 and 2012, 71% of men had their testosterone level checked once, 40% twice, and 29% had no measurement at baseline.  Physicians need to do a better job following men on testosterone replacement. Is testosterone replacement therapy really all that good for anything aside from rejuvenation and virility? 

Let’s break this down to risks and benefits below:

Risks of Prostate Cancer
The most universal risk which has been the controversy of much discussion is the association with prostate cancer.  Clinicians remain concerned that Testosterone Replacement Therapy (TRT) can cause or stimulate prostate carcinogenesis and therefore they are reluctant to prescribe it for the aging male who has a higher risk of prostate cancer.  In the 1940s, Huggins and Hodges discovered the association of testosterone with prostate cancer by demonstrating that castration causes the disease to regress. The reality is that TRT may stimulate the growth of existing prostate cancer cells, but it will not cause cancer to form.  As the general male population grows, so does the risk for prostate cancer--patients should be closely evaluated with digital rectal examinations, PSA checks and prostate imaging such as color Doppler ultrasound.

Risk of Prostate Enlargement
Another controversial topic is the assumption that supplemental testosterone leads to a prostate growth, benign prostate hypertrophy, which leads to worse quality of life due to worsening urinary symptoms.  It has long been assumed that high T levels induce prostate overgrowth, but most studies failed to find the correlation between circulating T levels and BPH.  It has been hypothesized that dihydrotestosterone (DHT) could be more responsible for prostate growth than T.  There have been a number of studies evaluating TRT in hypo-gonadal men with BPH.  The results have suggested that there is actually a trend toward an improvement in urinary symptoms.

Risk of High Red Counts—Polycythemia or Erythrocytosis
Erythrocytosis is the increase in red blood cell mass production which can be the result of testosterone replacement therapy.  This is the most frequent adverse effect associated with TRT.  Recent trials have demonstrated that men on TRT have a 4 times higher chance of having high red blood cell counts.  Some reports have implicated excessively high red blood cell levels with an increased risk for heart attack or stroke. We commonly recommend patients remain on a baby aspirin daily and monitor their blood counts. Some patients may benefit by donating a unit of blood if the levels are too high.

Risk of Obstructive Sleep Apnea
Frequently reported in various literature is the association of worsening sleep apnea symptoms for men on testosterone replacement.  There has been only one randomized control trial to date that addresses this association and it showed that obese men with severe sleep apnea may worsen their oxygenation with TRT at relatively high doses.  This study evaluated injection formulations of testosterone. So far transdermal formulations have not been similarly implicated.

Risk of Infertility
Testosterone replacement leads to inhibition of the pituitary gland located at the base of the brain which can potentially suppress the production of sperm.  Hence, cases of TRT-induced male infertility have been reported. This impact appears to be transient and disappears once TRT is stopped.

Improved Sexual Function
A decreased libido and/or potency remains one of the most common reasons that men desire testosterone replacement.  TRT can certainly improve sexual function in those who have erectile dysfunction primarily due to a low level of testosterone.  Patients need to recognize that there are a series of other reasons for being impotent that are unrelated to low levels of testosterone which must also be investigated as well before concluding that TRT will be the optimal corrective measure.

Improved Cardiovascular Effects
The association of TRT with heart attacks has been very controversial. We must not forget that men with low T levels are at higher risk for poor health due to being more frail and susceptible to other medical issues including obesity and diabetes. As a result, they become more prone to adverse cardiovascular outcomes.  Four out of five of the most recent meta-analyses demonstrated neither a protective or harmful effect of TRT on cardiovascular events. In men with heart failure, it has been demonstrated that low T levels are an independent risk factor for worse outcomes.  Studies also demonstrated that men with heart failure who supplemented with testosterone had a better exercise capacity, oxygen levels, and less fatigue.

Improved Metabolic Effects
Large scale data exists to document the association of low T and worsening blood sugar levels along with a higher chance of developing diabetes. TRT can improve body composition and help to reduce fat which can lead to better control of diabetes.

Reversal of Osteoporosis
Lower testosterone levels are associated with a higher risk of bone fractures and worsening bone health.  TRT has been demonstrated to have a positive effect on bone mineral density.

Improvement in Chronic Kidney Disease
Low T is very common (approximately 50%) in men undergoing dialysis for end stage renal disease. Reduced T levels have in men on hemodialysis have been tied to higher rates of all-cause cardiovascular mortality.   Studies suggest that TRT may improve the levels of a hormone called erythropoeitin (EPO). This hormone stimulates improved production of red blood cells which in turn increases levels of red blood cell mass, energy, stamina, and overall well-being.

It is clear to see that testosterone replacement offers a multitude of benefits which span past merely increasing one’s libido or potency.  The bottom line remains that patients on testosterone supplementation must have close follow-up including both clinical and laboratory evaluation to ensure they are gaining benefit and not placing themselves at increased risk from potential adverse effects.  Physicians must clearly discuss the risks and benefits of supplementation along with employing routine monitoring of PSA, testosterone levels, blood counts, digital rectal examination, and color Doppler ultrasound.
