  • OBJECTIVE: To investigate the oncologic safety of neurovascular bundles (NVB) preservation at radical prostatectomy (RP) in patients with high-risk and/or locally advanced prostate cancer (PCa).

    MATERIAL AND METHODS: Within a two-institutional high-volume center database we identified patients who harbored high-risk PCa at RP (2000-2017). Only patients with D'Amico high-risk PCa were included. Kaplan-Meier and multivariable Cox regression models tested the effect of NVB preservation on biochemical recurrence (BCR), metastasis and overall survival (OS). Subgroup analyses focused on patients with clinical stage T3 and/or biopsy ISUP grade 5 and pathologic stage T3.

    RESULTS: Of 4351 patients with D'Amico high-risk, 35.7% vs. 38.0% vs. 26.3% underwent bilateral vs. unilateral vs. no NVB preservation, respectively. At 120 months after RP BCR-free, metastasis-free survival and OS rates were 62.2% vs. 44.3% vs. 27.1% (p < 0.001), 83.7% vs. 66.7% vs. 60.3% (p < 0.001), and 91.8% vs. 87.5% vs. 72.3% (p < 0.001) for bilateral vs. unilateral vs. no NVB preservation, respectively. In multivariable Cox regression models, bilateral and unilateral compared to no NVB preservation did not increase the risk for BCR, metastasis or death in the entire cohort and in subgroups with clinical stage T3 and/or biopsy ISUP grade 5, as well as pathologic stage T3.

    CONCLUSIONS: NVB preservation was not associated with worse oncological outcome in patients with high-risk and/or locally advanced PCa and may be offered to well-selected patients who are at risk of harboring nonorgan-confined PCa.
