Text: At a median follow-up of 7. 2 years, failure to obtain a PSA-CR was associated significantly with worse disease-specific survival (P =. 0003 ; hazard ratio [HR], 2. 03 ; 95 % confidence interval [CI], 1. 38-2. 97), with worse disease-free survival (P =. 003 ; HR, 1. 28 ; 95 % CI, 1. 09-1. 50), and with a higher incidence of distant metastasis (P =. 0002 ; HR, 1. 92 ; 95 % CI, 1. 37-2. 69) and biochemical failure (P <. 0001 ; HR, 1. 57 ; 95 % CI, 1. 29-1. 91).
