Endometrial carcinoma: the interplay of genetics and hormones

Trans Am Clin Climatol Assoc. 2023;133:274-282.ABSTRACTEndometrial carcinoma is the most common malignancy of the genital tract in females in the United States, and it is one of the few human cancers increasing in incidence and mortality. Numerous studies have found an association of endometrial carcinoma with obesity, diabetes, and unopposed estrogen stimulation. Molecular studies, in our lab and others, have shown that endometrial carcinoma has a high frequency of alterations in the Phosphoinositide 3-kinase (PIK3) pathway, and notably, coexisting abnormalities in more than one member of the pathway are common. We have combined studies on primary human tumors and genetic mouse models to explore the role of the PIK3 pathway and estrogen, and their interactions, in the development and progression of endometrial carcinoma. Abnormalities in the PIK3 pathway do not simply play redundant roles in endometrial carcinoma and, although not required, the presence of estrogen can alter the course of the disease.PMID:37701602
