De novo post-diagnosis statin use, breast cancer-specific and overall mortality in women with stage I-III breast cancer.

ABSTRACT:

Background

Prior evidence suggests a role for statins in the management of cancer. However, the benefit of statin use in the adjuvant setting remains uncertain. This study investigates associations between statin use initiated after a breast cancer diagnosis and mortality.

Methods

Women with stage I-III breast cancer were identified from the National Cancer Registry of Ireland (N=4243). Post-diagnostic statin initiators were identified from pharmacy claims data (N=837). Multivariate models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between de novo statin use and mortality.

Results

The median duration of statin use was 6.7 years. No association was found between post-diagnostic statin use and breast cancer-specific (HR
