ADT after prostate surgery can show very good results for high-risk patients.
This study tried to compare ADT+Mitoxantrone and "just ADT" for two years starting right after surgery. There were 481 patients in the "just ADT" arm of the study and 87% of these were still alive ten years after surgery. And probably these will not die right after these ten years. Mitoxantrone in the other arm did show no benefit, there was almost the same result.
