Plasma oestrogens in postmenopausal women with endometrial cancer

Abstract

Patients with endometrial cancer exhibit increased plasma levels of oestradiol and oestrone. Speculatively, these oestrogens may result from an increased oestrone conversion from androstenedione, an increased ovarian and adrenal secretion of androstenedione, or alternative oestrogen production routes. The present findings support the hypothetical role for oestrogens in the aetiology of endometrial cancer.
