I think you should be talking to a radiation oncologist about
this now, and not a urologist.
If there is one circumstance where we
know that adjuvant radiation is the best thing to do, it is one like yours where the PSA has never become undetectable after surgery. Your rising PSA has already been confirmed at 5 weeks (Feb 5) and at 5 months (May 13), and it is doubling quickly, indicating imminent breakout. Any presence of Gleason pattern 5 (even at low levels) is highly prognostic for metastasis.
Three important clinical trials have now proved the benefit of earlier radiation over waiting. What are you waiting for? It won't go away on its own, and the longer you wait, the higher the chance it will metastasize (if it hasn't already). My only question would be whether it's broken out distantly already, and may be too late for adjuvant RT. You may want to request a bone scan and CT, although your PSA may be too low for detection with those.
You also need a different radiation oncologist. The method yours is using, 3D-CRT, is outdated and the amount of radiation is too low (it is low
because the equipment is outdated - toxicity would be too high with higher doses on that machine). At the better radiation centers, a different method called IGRT/IMRT has replaced 3D-CRT. Because of your incontinence, you need a much more accurate kind of radiation to protect the bladder.
As for the adjuvant ADT, yes, you will need some. Just how much is an
open question - answers range from 4 months to 2 years. It has proven benefit in cases like yours. Because they start ADT 2 months before radiation, and because of your high metastatic potential, I think you will want to get started on it ASAP.
I know this isn't what you want to hear, and your first instinct is to curl up and hide.
