Hi Phil: The PSMA Pet Scan should be highly accurate (90% accurate) in pinpointing where the culprit might be - in the original prostate bed or elsewhere. My guess is that in a salvage radiation (post-surgery) situation, they will be pretty adamant about administering 6-months of ADT. That said, there are multiple new hormone therapies that have evolved that have less metabolic impacts than the traditional ADT (Eligard) that I had in conjunction with my proton radiation. You may have to pay out-of-pocket for it and be assertive with them to go in that direction but for sure let them know you want to know all the alternatives. On a positive note, a friend of mine had recurrence 5 years following proton radiation - had 6-months of traditional ADT with some targeted radiation and so far so good. The advent of the PSMA scan prior to surgery or radiation has been a game changer. And it will be your friend as well, because they will know exactly where to go with any salvage radiation. Stay positive! This is a lifelong affliction and journey for all of us but the advancements in the past few years are on our side Phil. Wait for your scan and go from there. It's easy. They give you a shot - you wait for half an hour for it to permeate your system - the scan itself takes a few minutes. All the best tomorrow. I just tripped off my dock today and broke my ankle so one more hill to climb! Just have to stay positive.
