Introduction of robot-assisted radical prostatectomy (RARP) has revolutionized the therapeutic landscape of organ-confined prostate cancer (PCa). However, comparative analyses focused on health-related quality of life (HRQOL) after RARP and open retropubic prostatectomy (ORP) are sparse.
In the current retrospective analysis, inclusion criteria encompassed PSA ≤ 10 ng/ml, ≤ pT2c, ISUP ≤ 3, age ≤ 65 years, and preoperative continence. A propensity score-matched patient cohort [n = 418 (ORP: 209, RARP: 209)] was created and HRQOL was prospectively assessed based on validated questionnaires (EORTC QLQ-C30) preoperatively, 3 months, 12 months, and 24 months postoperatively. Primary endpoint was good general HRQOL based on previously published cut-off values. Erectile function was measured via IIEF-5, urinary continence via ICIQ-SF questionnaire. Multivariable analysis included binary logistic regression models (p < 0.05).
Open retropubic prostatectomy and RARP cohorts were well balanced. General HRQOL was significantly higher for ORP compared to RARP after 3 months (70.1 vs. 61.6, p = 0.001), but not at the remaining follow-up time points. There were no significant differences for the remaining QLQ-C30 functioning and symptom scores. In multivariable analysis stratified for IIEF-5 and ICIQ-SF scores and surgeon experience, RARP could be confirmed as a marginally independent predictor for lower ratios of good general HRQOL after 3 months (OR 0.464, 95% CI 0.215-0.999; p = 0.050) without any differences at the remaining time points.
The current study addresses various HRQOL outcomes over a postoperative period of up to 2 years in a homogenous propensity score-matched contemporary cohort. Marginally better general HRQOL outcomes could be detected for ORP compared to RARP 3 months postoperatively.
