Deflazacort and Fluoximesterone in Advanced,Pretreated Breast Cancer

Abstract

A very simple, low dose, orally administered regime (10 to 15 mg of fluoximesterone + 6 mg of deflazacort daily for periods of 1 to several months) resulting in mild-acceptable toxicity (essentially some weight gain) determined subjective improvement In 2/3 of 34 evaluable patients (out of 36 treated) and an objective measurable tumor reduction in 1/3, although most patients had been previously treated with chemotherapy and hormone treatment and proved primarily or secondarily refractory. The receptor status at the beginning of fluoximesterone + deflazacort treatment was not known, except in one negative-receptor patient, who responded to the combination after becoming resistant to tamoxifen (see photo). In some patients the condition of hormone refractoriness would suggest a no-treatment policy, but a trial with this regime is always convenient as it may improve both duration and quality of life.
