Systematic Review of Efficacy and Health Economic Implications of Real-world Treatment Sequencing in Prostate Cancer: Where Do the Newer Agents Enzalutamide and Abiraterone Fit in?

Abstract

CONTEXT: Optimal treatment sequencing of abiraterone and enzalutamide in chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC) is challenging. Real-world data (RWD) allow a better understanding of health economic implications in the real world. OBJECTIVE: To determine survival and cost outcomes for two real-world treatment sequences, comparing abiraterone to enzalutamide (AA → ENZ) with enzalutamide to abiraterone (ENZ → AA). EVIDENCE ACQUISITION: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Searches were performed in Medline, Embase, and Web of Science. EVIDENCE SYNTHESIS: Seven..
