title: Ethinyl estradiol and medroxyprogesterone treatment in advanced breast cancer: a pilot study.
abstract: Twenty patients with disseminated breast cancer unresponsive to conventional chemotherapy and chemohormonotherapy were treated with an alternating sequential schedule of ethinyl estradiol and medroxyprogesterone on the basis of correlations between hormones and estrogen and progestin receptors. Of 19 evaluable patients, six underwent partial or complete remission, while five others showed minor responses.
