Racial‐ethnic variations in phyllodes tumors among a multicenter United States cohort

Abstract

Background and objectives: Previous studies have identified racial-ethnic differences in the diagnostic patterns and recurrence outcomes of women with phyllodes tumors (PT).However, these studies are generally limited in size and generalizability. We therefore sought to explore racial-ethnic differences in age, tumor size, subtype, and recurrence in a large US cohort of women with PT.

Non-Hispanic Other women had a larger
