Abstract

Breast cancer (BC) is the second leading cause of cancer death among women in Western Countries. Beta-blocker (BB) drugs, angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB) were suggested to have a favorable role in the development and progression of BC. We have performed a meta-analysis to clarify the potential benefits of these drugs on BC survival. A total number of 46 265 BC patients from eleven papers were included, ten independent studies on BB use and seven on ACEi/ARB use. The summary hazard ratio (SHR) was estimated by pooling the study-specific estimates with random effects models and maximum likelihood estimation. We assessed the homogeneity of the effects across studies and evaluated between-study heterogeneity by meta-regression and sensitivity analyses. We found a significant improvement in BC specific survival for patients treated with BB drugs at the time of BC diagnosis (SHR: 0.44; 95%CI: 0.26-0.73 with I(2) = 78%). We also observed a borderline significant improvement in disease free survival for subjects treated with BB (SHR: 0.71, 95%CI: 0.19-1.03). No association of ACEi/ARB use with disease free and overall survival was found. In conclusion, we report epidemiological evidence that BB improve BC-specific survival. Clinical trials addressing this hypothesis are warranted.
