PSA is within normal limits.
My suggestions from my own personal experience is Decipher test. I got the same intermediate risk from Gleason Score and was to have radiation and hormone treatment. My Decipher came back low risk not intermediate. So no hormone treatments recommended.

PSMA test yes. I had it also and mine was negative. Can add evidence that cancer is still in prostate. But remember that a lot of the prostate cancers are still at the cellular level and hard to detect. But the PSMA test is excellent to help with diagnosis and treatment plans. I also had bone scan and it was also negative.

He is seeing both a urologist and oncologist/urologist. That is good. Going to get a lot of recommendations for treatment. Make sure you discuss all with his doctors to include radiations and surgeries not just one but both. I had 30 rounds of proton radiation.

Good luck and if in double about diagnosis or treatment plans suggest second opinion. That really helps you decide and I had 3 separate medical professionals opinions done before I made final decision with final consultation with my PCP.

It appears you have an experienced urologist and will be seeing a oncologist/urologist. Just know many urologist lean (just a comment not a fact) surgery. So ensure your husband gets briefed on all the pros and cons of all PC treatments so can make informed decision of what is best for him and you.
