Prostate-specific antigen doubling-time (PSA DT) before onset of chemotherapy as survival predictor for hormone refractory prostate cancer (HRPC) patients
Background: PSA DT has been reported as a prognostic factor in prostate cancer patients (pts) who relapse after radical prostatectomy, radiation or hormonal therapy. The rate at which the PSA is rising is known to correlate with cancer aggressiveness. We evaluated the interest of the initial PSA DT value, before start of chemotherapy (CT), as a surrogate end point for survival of metastatic HRPC pts. Methods: PSA DT was calculated as log x 2 divided
