SPPORT trial findings may be helpful.
Also rising PSA after treatment Jan 2023 video PCF.org.
BCR (PSA .19) immediately after RP led to radiation treatment of the whole pelvic region (WPRT) together with the pelvic lymph nodes.
Also 4 mos of ADT.
I thought that I saw the SPPORT trial recommendation was 4 - 6 mos ADT for intermediate PCa and 18 - 24 mos for aggressive disease.
however , I have not been able to re-locate that information.
My Gleason score was a 9, together with 8s.
However my Rad Onc prescribed 4 mos ADT.
2 "radiation buddies " received 6 mos ADT.
And I am not entirely sure why my ADT course was only 4 mos.
I chose Center of Excellence for treatment, so I am having faith.
1st PSA 6 mos following completion of 37 radiation txs (66.6 gy) and ADT undetectable. I will feel better if PSA remains undetectable for at least a couple more tests, but so far so good.
Sincere best wishes.
