PSA after Salvage RT, can anyone shed any light?

Just wondering if anyone has any understanding why 2 months after SRT my husbands PSA is still at it’s pre-treatment level of 0.2. 
I was expecting it to drop back to <O.1 if the treatment had been successful, or is it just too soon to read anything into it. He has his oncology appointment next week so can ask the question, but I am impatiently trying to find out what this PSA result could mean. 
He worries that the achy groiny sensation has come back, the same one that he had just before his PSA showed an increase a few months ago, but stopped during the RT, so he’s very concerned.

I had SRT but was also on hormone therapy.  I can't remember how long it took for my PSA to fall.  To get a quick answer why not try the specialist nurses?

It took about 3.5 years for my PSA to reach its nadir following ART

It doesn't mean anything at this stage - your onco will be looking for the PSA to fall to its lowest point about 18 months after the RT finished.

Did they not put him on hormone therapy with the SRT?

Agree with Lyn. RT does not kill cancer cells straight away. It kills them when they next try and divide, and with PCa being a slow cancer that will be many months or even years. So expect a gradual decrease over the next 18 months or so.

Thank you, my understanding is much clearer now.
He has already had 6 months of HT last year before and after the RP. Maybe they didn’t want to overuse HT, I’m still not sure of the rationale behind the timing and duration of HT use. I guess it’s just what the onco feels is most suitable for each individual.

I would ask about the HT, you are normally on it for at least 18 months for Salvage RT

They aren't going to start him on HT 2 months after he finished ART / SRT; it would prevent them from being able to monitor over time whether the RT has been successful. Presumably, he is under one of those oncos that thinks HT is unnecessary with SRT. 

 

If the PSA rises over the next few months rather than falling, the HT will be long term.

They did talk about chemo as a possibility alongside SRT if the CAT scan showed any tumour outside of the RT treatable area, but nothing was seen, so chemo was not needed. Only the prostrate bed was treated. No mention of HT.
I had assumed that long term HT would be  the next line of treatment if this wasn’t successful. That would mean coming to terms with being incurable and just holding it back for as long as possible I guess.
