Beta blocker use and breast cancer survival by subtypes: A population-based cohort study.

ABSTRACT:

Background

The associations between beta blocker (BB) use and breast cancer outcomes have been examined in previous observational studies, however the results are inconsistent. We examine these associations in a large population-based cohort of New Zealand (NZ) women with breast cancer.

Methods

Postmenopausal women diagnosed with a first primary early invasive breast cancer between 2006 and 2020 were identified from the NZ Breast Cancer Foundation National Register and linked to national pharmaceutical data, hospital discharges, and death records. Cox proportional hazard models were used to estimate hazards of breast cancer-specific death (BCD), recurrence free interval (RFI), and distant recurrence free interval (DRFI) associated with BB use at diagnosis. Analyses were stra
