[Determination of estradiol-17 beta receptors in tumorous breast tissue as an index of the hormonal dependence of the tumor].

To judge the hormone-dependence of mammary tumors the technic of tissue sections was employed, which were examined for the presence of oestradiol-17 beta receptors. Under examination were 192 patients, 78 of them being in their reproductive age and 14 menopausal patients. Oestradiol-17 beta receptors were found in the tumor material from 42.7% of patients.
