Estrogen receptors and histopathological evaluation of human breast cancer.

The breast cancers with positive ER, the anaplastic low level and the node non involvement were identified with good prognostic values. The positive estrogen receptors in 52 primary breast carcinomas were correlated with either big or small tumors, with node involvement or without it and either with or without sinus histocitosis reaction. The vascular and lymph infiltration, the undifferentiated and half-differentiated carcinomas, the high stroma component and the high number of mitosis were other parameters with were opposed to positive ER tumors. The prevailing age of the patients was postmenopausal.
