To assess the associations between prediagnostic and postdiagnostic statin use and all-cause and breast cancer-specific survival according to different intrinsic breast cancer subtypes in patients with early breast cancer.
Key Findings:
Statin use may be associated with improved survival outcomes in breast cancer patients.
Previous studies have shown a more pronounced benefit of statin use in hormone receptor-positive breast cancer.
No studies have specifically examined the outcomes of statin therapy across different intrinsic breast cancer subtypes.
Interpretation:
Limitations:
The study is retrospective and relies on existing registry data.
Statin use was assessed through prescription data, which may not capture all usage patterns.
