Estrogen production and metabolism in normal postmenopausal women and postmenopausal women with breast or endometrial cancer. 1986

M J Reed, and P A Beranek, and M W Ghilchik, and V H James

The metabolic clearance rates of estradiol in postmenopausal women with breast cancer (1269 +/- 370 1/24 hr, mean +/- S.D.) or endometrial cancer (1320 +/- 238 1/24 hr) were significantly higher than in normal postmenopausal women (922 +/- 238 1/24 hr). The metabolic clearance rates of estrone were elevated in women with endometrial cancer (2012 +/- 749 1/24 hr) or with conditions associated with an increased risk for breast or endometrial cancer (1830 +/- 413 1/24 hr) compared with values for normal postmenopausal women (1321 +/- 301 1/24 hr). The production rate of estradiol was only increased in women with breast cancer. Significant correlations were found between subjects' percentage of ideal body wt and the metabolic clearance rates of estrone and estradiol and also the production rate of estrone. The increased clearance rates may reflect differences in either the binding of estrogens to plasma proteins or the tissue metabolism of estrogens in cancer patients.

D004714	Endometrial Hyperplasia	Benign proliferation of the ENDOMETRIUM in the UTERUS. Endometrial hyperplasia is classified by its cytology and glandular tissue. There are simple, complex (adenomatous without atypia), and atypical hyperplasia representing also the ascending risk of becoming malignant.

D004958	Estradiol	The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids.	17 beta-Estradiol,Estradiol-17 beta,Oestradiol,17 beta-Oestradiol,Aerodiol,Delestrogen,Estrace,Estraderm TTS,Estradiol Anhydrous,Estradiol Hemihydrate,Estradiol Hemihydrate, (17 alpha)-Isomer,Estradiol Monohydrate,Estradiol Valerate,Estradiol Valeriante,Estradiol, (+-)-Isomer,Estradiol, (-)-Isomer,Estradiol, (16 alpha,17 alpha)-Isomer,Estradiol, (16 alpha,17 beta)-Isomer,Estradiol, (17-alpha)-Isomer,Estradiol, (8 alpha,17 beta)-(+-)-Isomer,Estradiol, (8 alpha,17 beta)-Isomer,Estradiol, (9 beta,17 alpha)-Isomer,Estradiol, (9 beta,17 beta)-Isomer,Estradiol, Monosodium Salt,Estradiol, Sodium Salt,Estradiol-17 alpha,Estradiol-17beta,Ovocyclin,Progynon-Depot,Progynova,Vivelle,17 beta Estradiol,17 beta Oestradiol,Estradiol 17 alpha,Estradiol 17 beta,Estradiol 17beta,Progynon Depot
D004970	Estrone	An aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone, a major mammalian estrogen. It is converted from ANDROSTENEDIONE directly, or from TESTOSTERONE via ESTRADIOL. In humans, it is produced primarily by the cyclic ovaries, PLACENTA, and the ADIPOSE TISSUE of men and postmenopausal women.
