Treatment decision satisfaction and regret after focal HIFU for localized prostate cancer.

Focal therapies (FTs) are investigated within prospective studies on selected patients treated for localized prostate cancer (PCa). Benefits are preservation of genitourinary function and reduced complications, but follow-up is elaborate and is associated with uncertainty as cancer-free survival appears to be lower compared to standard radical treatments. The aim of this study was to analyse patient-reported acceptance of FT and evaluate factors associated with treatment decision regret.

52 patients who received focal high-intensity focused ultrasound for low- to intermediate-risk PCa between 2014 and 2019 within two prospective trials were eligible for a survey regarding PCa-related treatment regret and quality-of-life (Clark's scale) and the following potential predictors: sociodemographic variables, Charlson Comorbidity Index, subjective aging (AARC-10 SF), and general health-related quality-of-life (SF-12). Cancer persistence/recurrence (multiparametric MRI and fusion biopsy after 12 months) and functional outcomes (EPIC-26 UI/UIO/S) data were also included in this study.

The overall survey response rate was 92.3% (48/52 patients). Median follow-up was 38 months (interquartile range = 25-50 months). In total, ten patients (20.8%) reported treatment decision regret. In univariable analyses, a clinically meaningful increase in urinary incontinence showed a significant association (OR 4.43; 95% CI 0.99-20.53; p = 0.049) with regret. Cancer recurrence (OR 12.31; 95% CI 1.78-159.26; p = 0.023) and general health worry as a domain of Clark's scale (OR 1.07; 95% CI 1.03-1.14; p < 0.01) were predictors of regret in a multivariable logistic regression model (AUC = 0.892).

Acceptance of FT is comparable to standard treatments. Extensive follow-up including regular PSA testing does not cause additional regret but careful patient selection and information before FT is crucial.
