This study assessed whether cT2c tumors without other high-risk factors (clinical stage T2c, not otherwise specified [cT2c-NOS]) behaved as an intermediate or high risk through an analysis of biochemical recurrence (BCR) after radical prostatectomy. METHODS: Two thousand seven hundred fifty-nine men from the Shared Equal Access Regional Cancer Hospital (SEARCH) Database and 12,900 men from Johns Hopkins Hospital (JHH) from 1988-2011 and 1982-2012, respectively, were analyzed. Patients were grouped into low-risk (prostate-specific antigen [PSA] < 10 ng/mL, Gleason sum ? 6, and cT1-T2a), intermediate-risk…(vermás)
