Abstract

Abstract : Background: Rates of metastatic progression (MP) and prostate cancer mortality (PCSM) are variable after biochemical recurrence (BCR) in patients who underwent radical prostatectomy (RP). To describe long‐term oncological outcomes of BCR patients and to analyze risk factors for further outcomes in these men with a special focus on RP‐BCR time. Methods: We retrospectively analyzed the data of 5509 RP patients treated between 1992 and 2006. Of those, we included 1321 patients who experienced BCR (PSA level ≥0.2 ng/mL) and did not receive any neoadjuvant or adjuvant therapy. Kaplan‐Meier and time dependent Cox regression models were used. Results: Median follow‐up was 121 months. MP was recorded in 177 (13.4%), PCSM in 126 (9.5%), and overall mortality (OM) in 264 (20.0%) patients. Patients with MP had worse tumor characteristics such as higher Gleason Scores (GS), rapid PSA doubling‐time (DT), and shorter RP‐BCR time intervals. MP‐free, PCSM‐free, and overall survival rates were significantly worse in patients with RP‐BCR time of <12 months versus patients with 12‐35.9 or ≥36 months ( P ≤ 0.001). Besides higher GS and rapid PSA‐DT, RP‐BCR time independently predicted MP, PCSM, and OM in multivariable regression analyses. Relative to the intermediate and longest RP‐BCR time interval, the shortest interval (<12) carried the highest risk for all three endpoints. Conclusions: Only a small proportion of BCR patients proceed to MP or PCSM. Besides higher GS and rapid PSA‐DT a shorter RP‐BCR interval (<12 months) heralds the most aggressive phenotype for progression to all three examined endpoints: MP, PCSM, and OM.
