39 Background: Health-related quality of life (HRQoL) outcomes are important in treatment selection for prostate cancer. The Expanded Prostate Cancer Index Composite (EPIC) is a validated and widely-utilized HRQoL survey which accounts for newer radiotherapeutic, surgical, and hormonal treatment methods. We present a meta-analysis of patient reported HRQoL outcomes collected with EPIC and compare HRQoL trends with radiation therapy, surgery, or active surveillance as primary treatment. Methods: The PubMed database was systematically searched for all studies which presented data directly derived from the use of EPIC on patients with prostate cancer prior to 07/09/2014. All eligible studies were selected for either inclusion and analysis or exclusion based on pre-determined criteria. The data from included studies was compiled and a simulation-based estimation method using Approximate Bayesian Computation was performed to obtain missing standard deviation estimate. A longitudinal meta-analysis was conducted to estimate EPIC-profiles for each component using Bayesian p-spline method. Results: Over 4,000 studies were searched, 152 were deemed eligible, and 39 were included. The calculated mean summary score estimates are shown in the attached table. Conclusions: In the urinary domain, radical prostatectomy (RP) has lower acute scores than active surveillance (AS) or radiation therapy (RT) without long-term difference. In the bowel domain, RT has lower scores than AS or RP acutely and long-term. In the sexual domain, RT and RP have lower acute scores than AS. RP has lower scores than RT without long-term difference. In the hormonal domain, little difference was noted between modalities. [Table: see text]
