Ninety-two women with advanced breast cancer were allocated at random to receive either cytotoxic or endocrine treatment. Out of 45 women included in the cytotoxic treatment group, 22 (49%) achieved complete or partial remission of their disease, whereas of the 47 included in the endocrine treatment group, only 10 (21%) achieved such remission. Significantly longer survival times in the cytotoxic treatment group were most apparent among premenopausal women, 75% of such patients responding to cytotoxic drugs (median survival 46 weeks) compared with only 11% benefiting from ovarian ablation (median survival 12 weeks). In postmenopausal women with predominantly soft-tissue disease, however, additive hormonal treatment with tamoxifen produced remission rates and survival times equivalent to those produced by cytotoxic drugs.
