[Prognostic value of estrogen receptors in breast cancer (author's transl)].

Abstract

One hundred and ninety-one patients with operable breast cancer were followed for up to 34 months after operation and the early recurrence of disease was noted in relation to the presence or absence of estrogen receptor. Recurrence rates were significantly higher in patients whose tumors did not contain receptors than in those whose tumors did. The response to cytotoxic chemotherapy in patients with advanced breast carcinoma seems to be independent of the presence of E2R in cancer tissue.
