Abstract
Serum levels of total dehydroepiandrosterone and total estrone were determined in 18 postmenopausal women with carcinoma of the uterine corpus (stage I, grade 1–3) and in 40 healthy postmenopausal women. Elevated levels of both steroids were found in the carcinoma group, for dehydroepiandrosterone 2010±195 vs. 1299±117 nM, p<0.01, and for estrone 2.38±0.24 vs. 1.36±0.11 nM, p<0.001. Dehydroepiandrosterone as well as the precursors of estrone are almost exclusively of adrenal origin in the postmenopausal woman. Thus these findings indicate a role of the adrenal cortex in the etiology of corpus carcinoma, either by providing increased levels of substrate for the peripheral synthesis of estrone or a direct action of adrenal androgens on the endometrial tissue.
