Also, I am not a doctor nor an expert on anything. Respect for the medical arts and science is hard-wired into my DNA. However, I have frequently dropped doctors who can't answer my questions and became intimidated thereby. Hence, you are cautioned that my chosen Treatment Plan is not "establishment approved." Further, this post is not intended to be an Introduction to PCa but will include some abbrevs for common terms. Again, monotherapy is NOT suggested by anyone. I'm 73 and can afford to be a guinea pig.
And now, the next Episode of Game of Stones... (I humbly suggest you read my post "Upcoming appt. with urologist").
Good news/bad gnus
Yesterday I met with the top-shelf urologist here, not board certified oncologist but gladly shared what he knew about PCa, unlike uro-oncs I've wasted time with. After a few minutes, it became apparent I'd already covered most of the same area he had. Please ignore the " " below -- they're literary enhancement only. I wasn't able to record the consult for reasons explained below; none involved the good doctor refusing me.
Dr. K was amazed that I'd gone almost 2 years with a PSA <0.1 on casodex and finasteride. I failed to inform him of the ton of vitamins, supplements (both mineral and herbal [NOT CBD, ever!], minimal exercise, fresh air and 40-60 oz. distilled water/day). Then he mentioned that the efficacy of RadioTherapy (RT) diminishes radically if/when I go Castrate Resistant (CR). Testosterone (T) is the main meal for PCa, mostly produced in the testicles. Castration can be done physically, hormonally or chemically.
"Why should that be," asked I. "Just because the PCa cells have mutated (again) doesn't mean they're not still Ca, still lose reproductive ability when radiated."
"Mutant CRPC cells are more aggressive, more likely to metastacize," sayeth he. I did not know that, nor accept it without further research, as inclined as I am to believe Dr. K. Nobody gets everything right all the time, not even egomaniacs who think they do.
The "once the horses get outta the barn" thing (PCa cells escape the gland's "capsule") is among the first fears you develop after Diagnosis (dx), if you were lucky to have found out soon enough. I won't tell you of the guy in the PCa support group I attend, who had two PSA tests <2.4, went for MRI scans anyway, which were negative, then bizarrely went for a Biopsy (bx) and whammo, GL 4+5, metastases (mets) in Seminal Vesicles (SV). But I digress.
"As you know," continued Dr. K, "Much decision-making for Treatment (Tx) involves Risk Assessment (RA). IMHO, the potential damage of staying on casodex/finasteride is about equal to potential damage by RT." And all by itself, this line of reasoning + professional experienced opinion made the consult worth its weight in gold (metaphorically speaking).
What I came away with was: 1) supreme relief at finding a doc I trust; 2) as in ALL of life, it's a crapshoot; 3) Dr. Fernand Labrie, may God rest his genius soul, was tracking the least invasive Tx for localized, non-mCRPC via Combined Androgen (Hormone) Blockade (CAB, CHB). I'll roll the dice on that, rather than on RT.
Since I'm only using casodex (bicalutamide, which blocks PCa cells from UTILIZING testosterone), not combined with a Testosterone (T) PRODUCTION blocker (T is grrrreat! for almost all other organs, esp. my BRAIN!), the next step could be blocking T production as well, which I remain loathe to do.
Hormone Therapies (HT) to block T include a Luteinizing Hormone-Releasing Hormone (LHRH) agonist. As of Dec 18, 2019, LHRH agonists available in the US include: Leuprolide (Lupron, Eligard), Goserelin (Zoladex), Histrelin (Vantas) and Triptorelin (Trelstar). An LHRH agonist keeps testicles from making T by blocking other hormones needed to make it. Also called Gonadotropin-Releasing Hormone (GnRH) agonist.
I'm gonna stop here, having discovered interesting mis- and maybe dis-information on the Am. Ca. Soc. website, along with good info... which is typical all the hell over the internet. C'est la CyberSpace.
Oh yeah, why I failed to record the consult. In my last visit months ago to this particular med. grp, my cell-phone's voice recorder went kerflooey. I chalked it up to coincidence, that as soon as the appt ended, the voice recorder came right back on. This time, I wasn't so lucky, even though I hadn't used the damn thing! Not only did the voice recorder die, the entire phone's now dead as a doornail.
Stay in the fray, brothers. Do more homework; this shit never ends.
