Determinants of Prostate Cancer Specific Survival Following Radiation Therapy During the Prostate Specific Antigen Era

Abstract

Prostate cancer was a major cause of death during the first decade following RT for patients with clinically localized but high risk disease, and the cause of death for patients with a short PSA DT following RT was nearly always prostate cancer. These data provide evidence to propose the hypothesis that a short posttreatment PSA DT may serve as a possible surrogate for PCSD. Prospective validation is needed.
