Abstract

Background and objective: Radical prostatectomy (RP) is a common and widely used treatment for localized prostate cancer. Sequela following RP may include urinary incontinence and sexual dysfunction, outcomes which are recorded within a bi-national Prostate Cancer Outcomes Registry. The objective was to report population-wide urinary incontinence and sexual function outcomes recorded at 12 months following RP; and to quantify and explore factors associated with variation in outcome. Materials and methods: The Prostate Cancer Outcomes Registry of Australia and New Zealand (PCOR-ANZ) was used for this study. Participants were treated with radical prostatectomy between 2016 and 2020. Domain summary scores for urinary incontinence and sexual function from the EPIC-26 instrument were the main outcomes, taken at 12 months following surgery (6–18 months). "Major" urinary and sexual function bother were also assessed. Variation in outcomes was investigated using linear and logistic multivariable regression models adjusted for covariates: age, socioeconomic status, PSA at diagnosis, surgical technique, surgical specimen grade group, margin status, and clinician surgical volume. Results and conclusions: The analytic cohort included 13,083 men with the mean urinary incontinence domain score being 76/100 (SD = 25) with 9.2% reporting major bother. For sexual function, the mean score was 29/100 (SD = 26) with 46% reporting major bother. Of the examined variables, age at surgery and surgical volume category were most predictive of function, with disparities exceeding minimally important differences, though large variation was observed between urologists within volume categories. There is considerable variation in 12-month postprostatectomy functional outcomes. Variation is explained by both patient and clinician factors, though some confounders are unmeasured in this cohort.
