A Meta-Analysis Of Health-Related Quality Of Life After Primary Treatment For Prostate Cancer As Measured By The Expanded Prostate Cancer Index Composite.

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...
