Key clinical point: The use of β-blocker at the time of breast cancer (BC) diagnosis reduced mortality in patients with triple-negative BC (TNBC).
Major finding: Although β-blocker use vs no use was not associated with BC-specific survival in the overall population, β-blockers reduced BC mortality by 34% in patients with TNBC (hazard ratio [HR] 0.66; 95% CI 0.47-0.91). The meta-analysis further confirmed that β-blocker use was associated with progression/recurrence-free survival (HR 0.58; 95% CI 0.38-0.89) in the TNBC population.
Study details: Findings are from a large population-based cohort study including 30,060 women aged ≥ 50 years with primary invasive BC, of which 15% used β-blockers at the time of BC diagnosis, and from a meta-analysis of 8 observational studies.
