INTRODUCTION: Population-based breast cancer mortality rates are approximately 40% higher for AA compared to WA women.

Methods: We evaluated survival among AA and WA pts presenting with clinically early-stage/node negative breast cancer, stratified by having TNBC versus non-TNBC phenotype from a prospectively-maintained, IRB-approved database in an employee health plan-based hospital system serving a diverse community; Median follow-up was 60 months.
