Ovarian cancers arising from endometriosis: A microenvironmental biomarker study including ER, HNF1ß, p53, PTEN, BAF250a, and COX-2

Abstract

Our results supported the suggestion that estrogen-dependent ovarian cancer arising from endometriosis is substantially more associated with EM adenocarcinoma than CCCs. The positive HNF1ß staining was a frequent finding in CCCs, but not in EM adenocarcinoma. The similar staining patterns of atypical endometriosis glandular cells with the invasive parts confirmed their precursor status.
