I completed SBRT treatment for Gleason 7 (3+4) PCa at MSKCC in NYC in November 2021. My PSA was 8.7 right before the treatment.
During the past year:
-- My PSA dropped to 4.8 by March 2022; shot back up to 8.6 in June 2022 (due to a case of prostatitis); dropped to 3.9 in August 2022 (after a round of Cipro). My next scheduled PSA reading is scheduled for December 2022.
-- I've had no real urinary issues during the past year except for some bouts of urgency especially after sitting for a while or after long car rides.
-- I've had no bowel or rectal issues.
-- Sexual function has been inconsistent not because of erection problems (I'm still taking Sildenafil but I don't know if that has actually been a help or just a placebo because I've been on it since the treatment) -- It's more a matter of feelings and sensations, as it were. The sensations and triggers have changed a bit during sexual activity -- it takes a bit to get used to. Surprisingly enough, I still have some ejaculation even this amount of time after treatment.
If my PSA remains low and I remain cancer-free, then I feel the SBRT treatment was quite a gift because certain aspects have changed, but my quality of life remains excellent and the side effect, so far, have been very manageable.
