[Estrogen and progestogen cytosol receptors in human breast carcinoma (author's transl)]. 1977

F May-Levin, and F Guerinot, and G Contesso, and J C Delarue, and C Bohuon

The authors have studied Estrogen (RE) and Progestin (RP) cytosol receptors in 379 human breast carcinomas: 281 tumors suitable for surgery, 26 pseudo-inflammatory tumors, 52 metastases and 20 recurrences. They have used an exchange technique with estradiol for RE and a synthetic compound, R 5020, for RP. The results point out that high rates of RE correlate with post-menopausal women and high rates of RP with pre-menopausal women. Tumours are considered receptor-positive when the binding sites concentration exceeds 100 fmoles/g tissue. Using this as a base 32% of the tumors are RE and RP negative. Considering only the positive tumors, 54% contain both receptors, 31% only RE and 15% only RP. The percentages are also given in terms of the hormonal state of the patients. The results are discussed in terms of McGuire's hypothesis that both receptors are necessary to obtain a positive response to hormonal therapy. Correlation between histology and receptors is also discussed.

UI	MeSH Term	Description	Entries
D008593	Menopause	The last menstrual period. Permanent cessation of menses (MENSTRUATION) is usually defined after 6 to 12 months of AMENORRHEA in a woman over 45 years of age. In the United States, menopause generally occurs in women between 48 and 55 years of age.	Change of Life, Female
D009362	Neoplasm Metastasis	The transfer of a neoplasm from one organ or part of the body to another remote from the primary site.	Metastase,Metastasis,Metastases, Neoplasm,Metastasis, Neoplasm,Neoplasm Metastases,Metastases
D009364	Neoplasm Recurrence, Local	The local recurrence of a neoplasm following treatment. It arises from microscopic cells of the original neoplasm that have escaped therapeutic intervention and later become clinically visible at the original site.

D011960	Receptors, Estrogen	Cytoplasmic proteins that bind estrogens and migrate to the nucleus where they regulate DNA transcription. Evaluation of the state of estrogen receptors in breast cancer patients has become clinically important.

D011980	Receptors, Progesterone	Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.

D004958	Estradiol	The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position.
