[Specific cytoplasmic receptors for steroid homones in benign and malignant breast diseases, in normal glandular tissue and pectoral muscle].

An improvement to the DCC (destran-coated charcoal) method for determining receptors for 17-beta-oestradiol, 5-alpha-dihydrotestosterone and progesterone in benign and malignant breast conditions, normal glandular tissue and muscular tissue is reported. Preliminary results on 16 malignant cancers and 4 fibrocystic mastopathies are discussed together with a critical review of the technique employed and the results obtained in hormone competition.
