The effect of time on racial differences in epithelial ovarian cancer (OVCA) diagnosis stage, overall and by histologic subtypes: a study of the National Cancer Database

摘要

Previous studies assessing racial and ethnic differences in ovarian cancer (OVCA) diagnosis stage fail to present subtype-specific results and provide historic data on cases diagnosed between 10 and 20 years ago. The purpose of this analysis is to assess non-Hispanic Black (NHB) and non-Hispanic White (NHW) differences in late-stage diagnosis including; (1) factors associated with late-stage diagnosis of invasive epithelial OVCA overall and by histologic subtypes, (2) potential changes across time and (3) current patterns of trends in a national cancer registry in the USA and Puerto Rico between 1998 and 2011.
