Rise in PSA after

Is he still on ADT? or did that stop?

If he stopped ADT, PSA will rise a bit before leveling off.

It can take RT years to be fully effective.

Was this his primary treatment? Assuming it was:

The ADT will lower PSA to near zero. As his T-levels improve, his PSA will rise. If he's still having hot flashes then he might not have recovered fully his T-level.

The RT will have done it's damage to the PC, but that can take years (2-4) to get to full nidar, so it's possible that his PSA might rise as his T-level recovers and then start going back down as the RT finishes off the remain PC cells. If he still has a prostate, then his PSA will never hit "0" but could be very low - .2 or .4 or something in that range.

And at this PSA levels, scans would be useless as any remaining PC would be microscopic and not visible on a scan.

Likely he'll be just fine. Sadly, RT is the slow road and can stretch your patiences to the limit.

If needed (and hopefully not) he could still have Brachy if a follow up treatment is required at some mythical date in the future.

and in his case, nadir would be the lowest point after he recovers T-levels after ADT and then BCR is nidar +2 from that point. Honestly, unless you start seeing numbers like 1.0 or 2.0, you're golden and should be sending me an invitation to the blowout party you're planning to celebrate a successful treatment.

The immediate drop was most likely due to ADT. ADT needs to get out of his system before he can get a good reading.
