If you haven’t had metastasis and your PSA remains < .1, I would suggest taking a holiday from ADT. But first, I would suggest you ask your doctors to talk to each other, come up with a plan together and explain their reasoning to you. My medical oncologist is more enthusiastic about ADT than my radiation oncologist. I am currently off ADT for one year after three and a half on. So far, all is good. I had a single metastasis on my sacrum that was radiated.

NCCN recommend six months of ADT for a Gleason seven, but you had a reoccurrence that required salvage radiation. That means you have an aggressive prostate cancer and more than six months is recommended.

Were more issues found in your biopsy of the prostate? Does that explain why it came back?

12 years ago when my PSA rose to .2 3.5 years after a prostatectomy, I was only given an ADT shot before the 7+ weeks of radiation. It took 2 1/2 more years before my PSA started rising again and I had to go on Lupron.

You may be able to stop, but after a reoccurrence, it is very likely that the cancer will come back. If your PSA has stayed the same since radiation you could try stopping ADT, But I would get monthly PSA tests since you are very likely to have something reoccurred again. 10 years after I was diagnosed and had to prostatectomy I had a genetic test and found out I was BRCA2 And that’s why my cancer keeps coming back.

Getting an hereditary genetic test is a good idea. If you have certain genetic issues, there are new drugs to treat them. You can get one free here If you live in the United States.

They will send you a spit tube and in about three weeks a genetic counselor will call you to discuss the results. Don’t check the box to have your doctor involved. In that case they won’t send anything until they speak to your doctor.
