title: [Sex hormones in the systemic and local circulation in endometrial hyperplasia and neoplasia: correlation with the activity of estrogen-metabolizing enzymes].
abstract: Sex hormone profile was investigated in uterine systemic and local blood flow in endometrial hyperplasia and carcinoma. The results were compared with levels of aromatase and steroid sulfatase - estrogen metabolism enzymes. Local hyperestradiolemia and hyperestronemia were detected in cancer patients. Estradiol and estrone in endometrial hyperplasia were lower than in cancer which conforms to estrogen theory of hormonal carcinogenesis. There was no evidence for the role of hyperestrogenemia in endometrial hyperplasia development. Aromatase was a factor of intensified estrogen synthesis in altered and hyperplastic endometrium. There was an inverse correlation between intratumoral steroid sulfatase levels and those of estrone in uterine local blood flow.
