The impact of previous inguinal mesh hernioplasty on oncological and patient‐reported outcomes following radical prostatectomy

Abstract

AbstractBackgroundThe impact of previous inguinal mesh hernioplasty (MH) with non‐resorbable mesh prostheses on surgical performance of radical prostatectomy (RP) has been controversially discussed, with unknown impact of MH on oncologic outcomes and health‐related quality of life (HRQOL) following RP. We therefore aimed to assess the influence of previous MH on metastasis‐free survival (MFS), biochemical recurrence‐free survival (BRFS), and HRQOL following RP.MethodsWe identified 344 patients with previous MH prior RP within our prospectively assessed institutional database of 6275 patients treated with RP for PC (2008–2019). A 1:3 propensity‐score matched analysis of 1345 men (n = 319 previous MH, n = 1026 no previous MH) was conducted. Primary endpoint was MFS and secondary endpoints were BRFS and HRQOL (based on EORTC QLQ‐C30). Binary logistic regression, Kaplan–Meier, and Cox regression models tested the effect of previous MH on MFS, BRFS, and HRQOL (p < 0.05).ResultsMedian follow‐up was 47 months. Patients with previous MH had significantly lower 5‐year MFS (72% vs. 85%, p < 0.001) and 5‐year BRFS estimates (43% vs. 57%, p < 0.001). In multivariate analysis, previous MH was confirmed as an independent predictor for impaired MFS (hazard ratio [HR]: 3.772, 95% CI 1.12–12.64, p = 0.031) and BRFS (HR: 1.862, 95% CI: 1.22–2.85, p = 0.004). These results held true if stratified for surgical approach or limited to patients with successful PLND. We found significantly shorter median time to continence recovery for patients without previous MH (p = 0.001) without significant differences in total continence recovery rates, erectile function recovery, and HRQOL.ConclusionsOur findings show an impaired oncologic outcome for patients with previous MH following RP with no significant differences regarding continence recovery, erectile function recovery, and general HRQOL.
