Defining Predictors Of Early, Intermediate, And Late Biochemical Recurrence In Men With Clinically Localized Prostate Cancer Treated With Minimally Invasive Radical Prostatectomy.

113Background: Follow up after radical prostatectomy should be tailored to clinical and pathologic characteristics. To determine predictive factors for early, intermediate and late biochemical recurrence (BCR) after minimally invasive radical prostatectomy (MIRP: lap and robot) in patients with localized prostate cancer (PCa). Methods: Prospective clinical, pathologic, and outcome data were collected for 6195 patients with cT1-3N0M0 PCa treated with MIRP at our institution from 2000 to 2016. None of them received neoadjuvant therapy. BCR was defined as PSA level greater than 0.2 ng/ml. Time to BCR was divided in terciles to identify variables associated with early ( 36 months). Comparisons among groups were performed using ANOVA or Chi square test. Logistic regression models were built to determine risk factors associated with BCR at each time interval. Results: We identified 1148 (19%) patients with BCR. Median time to BCR was 24 months. Statisti...
