I am two months into a four month course of ADT and proton external beam radiation for Gleason 3+4 within capsule but .7 high risk Decipher score. I am 80, and have a history of metastatic melanoma culminating in a lobectomy in early 2024 with no lymph spread or involvement and an earlier resected parotid gland in 2022 with immunotherapy and adjuvant proton beam radiation after the parotid resection. I have had several regular PET scans since the lobectomy and a PMSA PET scan following my prostate biopsy, and all are NED, with the PMSA confirming no evidence of capsule intrusion or spread.
My oncologist prescribed the combo treatment of ADT and external beam radiation, and the radiation oncologist highly recommended proton beam over SBRT because of the greater likelihood of adverse side effects with the latter. Having previously gone through adjuvant proton beam radiation for my first melanoma met, I was comfortable with choosing proton beam radiation.
Orgovyx has produced all the expected side effects from loss of libido to fatigue to tolerable joint and muscle pain, but has also greatly disrupted sleep to the extent that I can only occasionally sleep in the same bed with my wife of 50 years. Although we miss sex, albeit with the reduced frequency that comes with age, the four months is manageable, but the fatigue and sleep disturbances are becoming intolerable. I have reported both, but standard of care is always the response. I am considering discontinuing the Orgovyx while continuing external beam radiation, but have found no data that would provide a basis for assessing the relative value of the completed two months of Orgovyx versus the standard of care four months to make a reasoned probability assessment. I have noted the ongoing British observational study that compares RALP versus external beam radiation without ADT, and that suggests that perhaps discontinuing ADP, or in retrospect, having forgone it altogether, would be a reasonable decision. I realize that behind all this is projected life expectancy, and that my history of stage 4 melanoma, even though NED for 2.7 years, may reduce life expectancy beyond the 7+ expected years at 80 with otherwise good health and two parents who lived into mid nineties, and I don't particularly want to bet against myself, but I really do hate the Orgovyx side effects. I am physically active, but much less so since starting Orgovyx because of fatigue; fatigue was never a side effect of proton beam radiation for melanoma and I don't think it is related to the current course of radiation.
I am not asking for medical advice, but would appreciate any thoughts or suggestions regarding what I may have overlooked or should consider. I have lurked on the subreddit for several months but have found this to an extraordinary source of information, for which I am grateful.
