161 Background: Multiparametric magnetic resonance imaging (mpMRI) used in conjunction with MR/TRUS fusion-guided biopsy has improved detection and localization of clinically significant prostate cancer. We aim to evaluate the utility of preoperative MRI characteristics to predict biochemical recurrence (BCR) following radical prostatectomy. Methods: Patients who underwent robotic assisted radical prostatectomy (RARP) between 2007-2014 at the National Institutes of Health were reviewed. We identified patients with BCR defined following the guidelines of the AUA Localized Prostate Cancer Update Panel report (serum PSA ≥0.2 ng/ml with a subsequent confirmatory value). Bivariate analysis and logistic regression were used to determine the association of mpMRI and preoperative patient characteristics with BCR. Results: Of 365 patients who had RARP, 21 met criteria for BCR with a median follow up of 19 months (IQR: 10-34). Mean preoperative PSA (ng/mL) [p<0.001], high MRI suspicion level [p=0.016], presence of ...
