A new anti-oestrogenic agent in late breast cancer. An early clinical appraisal of ICI46474

Abstract

An introductory clinical trial of the anti-oestrogenic agent IC146474 in late or recurrent carcinoma of the breast is described.Forty-six patients have been treated, of whom 10 have shown a good response. This is of the same order as that seen with oestrogens and androgens.The particular advantage of this drug is the low incidence of troublesome side effects.
