The whole idea is to live as long as possible while enduring as few side-effects as possible..Urologists and Medical Oncologists seldom see eye to eye...The 6 month, 9 month issue is minor. I would favor the oncologist in all things at this point, he was trained to do this. For urologists, it's a profitable sideline...JMHO....
You should know that the effect of the drugs does not wear off instantly..It will take several months for Dad's testosterone to recover and possibly stimulate his PC..The key measurement to survival will your Dad's PSA doubling time after the shot wears off..Hopefully, it will rise very slowly (what was his original Gleason score?) and there will be no rush to return to the ADT shots and allowing him time to recover from them..
When employing intermittent ADT, some oncologists keep the patient on Avodart, claiming it can extend the "time off" period without imposing any serious QL issues...
The bright side of all this, when a reoccurred PC takes 10 years to appear, these slow-growing cancers are usually fairly easy to control with the tools available to your oncologist....Best of luck to your Dad..
