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

BACKGROUND

The 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.

METHODS

We 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).

RESULTS

Median 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.

CONCLUSIONS

Our 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.

Laparoscopic Radical Prostatectomy Alone or With Laparoscopic Herniorrhaphy

BACKGROUND AND OBJECTIVES

Prostate cancer and inguinal hernia are common health issues in men aged more than 50 years. Recently, more data are accumulating that laparoscopic radical prostatectomy (LRP) and laparoscopic inguinal hernia repair (LIHR) can be performed in the same operation. The purpose of this study was to compare patients who underwent simultaneous extraperitoneal LRP (E-LRP) and LIHR with control patients who underwent only E-LRP in a matched-pairs design.

METHODS

Medical records of 215 patients were evaluated, and 20 patients who underwent E-LRP+LIHR were compared with 40 patients who underwent only E-LRP in a matched-pairs analysis. Preoperative clinical parameters (age, body mass index, prostate-specific antigen, clinical stage, Gleason score of the prostate biopsy, and prostate volume) and operative data (operation time, duration of catheterization, length of hospital stay, estimated blood loss, time to perform the anastomosis and its quality, and the percentage of patients with bilateral lymphadenectomy) were evaluated, as well as postoperative parameters (pathological stage, Gleason score, specimen weight, follow-up duration, biochemical recurrence, complication rates, and duration of postoperative analgesic treatment).

RESULTS

No statistically significant differences were found in the preoperative and operative parameters between the 2 study groups. Pathological parameters and the follow-up period and complication rates were similar between the 2 groups.

CONCLUSION

Performing LIHR and E-LRP during the same operation is safe and feasible in the treatment of patients with prostate cancer and inguinal hernia.
