I would like to learn of any other outcome experience.
Five years after my RALP, I became uPSA detectable in early 2017, slowly rising from mid .020's to ~.050 in December 2018. I decided to stop the T-cyp injections my uro had me on, and I have stayed off the juice since.
In the list below, the Dec 2018 blood draw was done just before I quit. The remainder shows a pretty steady level:
I have an endocrinologist appt. coming up and may possibly be able to approach my continuing low-T/very high estradiol problem via meds, like an aromatase inhibitor. Kinda like "back door" TRT, I guess. I will closely monitor my uPSA until I have figured something out or have just learned to live with it. Then back off on my uPSAs frequency to just every few months or so. You said you will be backing off the frequent monitoring, too. Probably good for both of us to do so.
But the thing is, my trend may not continue. It could accelerate in the future, stay same or even go down. Dr. Myers had a video out there years ago that said he had seen a number of men level off at .1, but he didn't say what characterized those that did so.
No telling what yours will do. But here are some rough calcs based on the some of the values you gave us:
(1) your uPSA rose .004 in 17 months (.007 07/18 to .011 12/19) which is a yearly rate of (.004 / 17) x 12 = .0028
(2) In 40 years, when you are age 100, your uPSA will be (.011 + .113) = ~.12
I rounded here and there, and chose just some of your numbers, but you see what I'm getting at. If your rate increases or decreases, you can redo the calcs, but that's all we have right now.
Bottom line, from what we see now, you are likely to die of something else before advanced PCa. Nobody is going to be able to guess what your uPSA future will be. It's fruitless to try. If the continuing anxiety from dealing with this is keeping you awake nights, there is no shame in talking it through with a professional or getting on some anti-anxiety meds for a while.
We are all trying to help, and hope best for you, but we cannot predict the future any more than you can.
