Development and validation of a preoperative nomogram for predicting positive surgical margins after laparoscopic radical prostatectomy

摘要

BackgroundPositive surgical margins are independent risk factor for biochemical recurrence, local recurrence, and distant metastasis after radical prostatectomy. However, limited predictive tools are available. This study aimed to develop and validate a preoperative nomogram for predicting positive surgical margins after laparoscopic radical prostatectomy (LRP).
