The clinical utility of the percent of positive prostate biopsies in predicting prostate-specific antigen (PSA) outcome following radical prostatectomy (RP), or external beam radiation therapy (RT), for men with PSA detected, or clinically palpable prostate cancer was investigated. After accounting for the established prognostic significance of the PSA level, biopsy Gleason score and the clinical T-stage, the percent of positive prostate biopsies added clinically significant information regarding time to PSA failure following RP. These findings were validated in the intermediate risk patients using an independent surgical and radiation data set.
