Basic and Clinical Relevance of Hormonal Influence in Breast Cancer
1990
In the Federal Republic of Germany breast cancer has a leading place among malignant tumors in women. Genital and breast cancers account for 32% of all female deaths from malignant neoplasias. The distribution of types of cancer is as follows: breast 52%, uterine cervix 9%, corpus uteri 4.5%, adnexae 19%, and other sex organs 15.5% (Maas and Sachs 1972; Schmidt-Matthiesen 1975, Vorherr 1980). Besides general epidemiological factors such as geographical distribution, dietary factors, age distribution, familial disposition, and socioeconomic influences, possible hormonal components are discussed in connection with the etiology of breast cancer (Fischedick and Lux 1977; Henderson et al. 1974; …
Lack of binding of gestodene to estrogen receptor in human breast cancer tissue
1990
Competition studies with progesterone and estradiol receptors of human myometrial tissue as well as of mammary cancer tissue showed that gestodene bound with high affinity to the progesterone receptor, as did other synthetic and natural progestogens. However, gestodene did not bind to the estradiol receptor. The relative binding affinities of all tested synthetic and natural ligands showed no organ-specific differences and no differences between neoplastically transformed and normal tissues.
