Adverse Health Outcomes 3 Years after Radical Prostatectomy Compared with Men in the General Population: A Study from the Cancer Registry of Norway

Introduction

Studies about adverse health outcomes (AHOs) after radical prostatectomy (RP) in population-based contemporary prostate cancer (PCa) patients are limited, as well as knowledge about corresponding data from age-similar men from the general population (Norms). We compared selected AHOs (pad use, intercourse inability), related problems (bother) and quality of life (QoL) between PCa patients and Norms.

Patients and methods

The Cancer Registry of Norway (CRN) provided data on PCa patients diagnosed in 2017-2019 and treated with RP who completed the EPIC-26 and EORTC-QLQ-C30 questionnaires 24-48 months after surgery (n = 1501). The CRN also established a group of Norms (n = 1894). Dichotomized EPIC-26 outcomes: daily use of ≥1 pad (Item#3), quality of erections (Item#9) and related bother (Item#4a/#12). EORTC-QLQ-C30: quality of life (Item#30). Multivariable logistic regressions explored associations between selected covariates and outcomes.

Results

In total, 41% of the patients and 5% in Norms reported pad use, the comparable figures for intercourse inability being 84% (Patients) and 48% (Norms). Among pad users, 24% of the patients and 25% of the Norms described bother. 52% of patients and 35% Norms with intercourse inability. Only bilateral nerve-sparing surgery (NSS) significantly reduced the risk of pad use and intercourse inability. Compared to Norms, PCa patients were associated with pad use, intercourse inability, related bother, and good/ fair QoL.

Conclusion

In these population-based cohorts, 2 in 5 patients used pads 3 years after RP, compared to 1 in 20 Norms. Intercourse inability was reported by 4 of 5 patients compared to 1 of 2 Norms. PCa patients were associated with good/ fair QoL. Bilateral NSS significantly reduced the risk of AHOs, highlighting the importance of this approach. Function and bother are different dimensions of urinary and sexual AHOs and must be reported separately. The findings from this study should be considered when counselling patients before RP.
