Treatments for metastatic hormone-sensitive prostate cancer: A systematic review.

346Background: Over the past few years, the treatment of metastatic hormone sensitive prostate cancer (mHSPC) was revolutionized with the addition of docetaxel (DOC) or abiraterone (ABI) to the previous standard of care androgen deprivation treatment (ADT). Here, we sought to compare the effectiveness of docetaxel and abiraterone directly against ADT and indirectly to each other. Methods: We included randomized controlled trials (RCT) evaluating the efficacy of treatments in adults with newly diagnosed mHSPC. First-line treatments with DOC and ABI were considered. Efficacy outcome measures are overall survival (OS) and failure-free survival as (FFS) as defined by individual trial. If FFS was not reported, biochemical progression-free survival was considered FFS due to its specificity. The overall effect was pooled using the DerSimonian random effects model. Testing for subgroup difference was conducted using meta-regression method. Results: A total of five RCTs were included; three RCTs compared DOC+ADT v...
