Survival was best for patients who underwent radical prostatectomy compared to radiotherapy or watchful waiting. This was true for patients of all races combined, as well as for all races individually, and especially for Caucasian men. Radiotherapy had at least equivalent survival outcomes to watchful waiting in all groups. The greatest difference between treatment types was noted for overall survival to a larger extent than CaP-specific survival. This did vary among races.
This retrospective study has similar studies published recently from Memorial Sloan-Kettering Cancer Center and UCSF. A validated prospective study providing definitive understanding will likely never be achieved.
