Background: Among women with endometrial cancer (EC), African American or Black (AAoB) population share a disproportionate burden of cancer deaths. Previous research exploring genetic and molecular explanations revealed White (W) women with EC are more likely to have mutations in PTEN, while AAoB women have higher rates of mutations in p53. However, these studies did not stratify EC by subtype, which occur at different rates among racial groups. Here, we aim to focus on molecular differences between racial groups, specifically in Type 1 EC (T1EC). Methods: Molecular data from TCGA Uterine Corpus Endometrial Carcinoma datasets on cBioPortal was used. Cancer type was filtered to Uterine Endometrioid Carcinoma Type 1 and separated by race. A total of 711 cases were analyzed for gene alterations, expression versus copy number variations, survival curves, and OncoPrints; significant …
