NeuroSAFE in radical prostatectomy increases the rate of nerve‐sparing surgery without affecting oncological outcome

Objectives To investigate the impact of intra‐operative neurovascular structure‐adjacent frozen‐section examination (NeuroSAFE) on the rate of nerve‐sparing surgery (NSS) and oncological outcome in a large radical prostatectomy (RP) cohort. Patients and methods Between January 2016 and December 2020, 1756 prostate cancer patients underwent robot‐assisted RP, of whom 959 (55%) underwent this with NeuroSAFE and 797 (45%) without (control cohort). In cases where NeuroSAFE showed tumour in the margin, a secondary resection was performed. The effect of NeuroSAFE on NSS and positive surgical margin (PSM) status was analysed using logistic regression. Cox regression was used to identify predictors of biochemical recurrence‐free survival (BCRFS). Results and limitations Patients in the NeuroSAFE cohort had a higher tumour grade (P
