Prospective Long-term Health-related Quality of Life Outcomes After Surgery, Radiotherapy, or Active Surveillance for Localized Prostate Cancer

Background: Localized prostate cancer (PCa) treatment is associated with reduced health-related quality of life (HRQoL). Current literature is limited by short-term follow-up. Objective: To prospectively evaluate the 5-yr HRQoL outcomes in men undergoing radical prostatectomy (RP), external beam radiotherapy (EBRT), or active surveillance (AS). Design, setting, and participants: We prospectively evaluated HRQoL in patients with low-risk/favorable intermediate-risk PCa enrolled in the Center for Prostate Disease Research multicenter database between 2007 and 2017. Intervention: Of 1012 patients included in the study, 252 (24.9%) underwent AS, 557 (55.0%) RP, and 203 (20.0%) EBRT. Patients complete the Expanded Prostate Cancer Index Composite and the 36-item Medical Outcomes Study Short Form at baseline and thereafter each year up to 5 yr after treatment. Outcome measurements and statistical analysis: Temporal changes in HRQoL were compared between treatments and were modeled using linear regression models adjusted for baseline HRQoL, demographic, and clinical characteristics. Results and limitations: RP showed the least irritative symptoms and worse incontinence in comparison with AS (p
