153P Prevalence and survival of stage IV male breast cancer: A SEER database analysis

Abstract

Male breast cancer (BC) is a rare disease, accounting for <1% of all BC cases in the United States. Delay in diagnosis can result from lack of awareness of the existence of BC among men. Since it is often late diagnosed, male BC remains a substantial cause of morbidity and mortality. The goal of this study was to evaluate the proportion of stage IV patients and their survival outcomes over time using SEER (Surveillance, Epidemiology, and End Results) data.
