A phase II study of cis-diamminedichloroplatinum II for advanced breast cancer. Two dose schedules

Thirty-six (36) women with metastatic breast cancer refractory to conventional therapies were treated with cis-diamminedichloroplatinum II. Two dose schedules were used sequentially. The first 15 patients received platinum at a dose of 15 mg/m2 daily for 5 days at 28-day intervals. No response was noted in this group. Subsequently, 21 patients were treated with a dose of 100-120 mg/m2 at 28-day intervals, but with additional induced diuresis with saline, furosemide, and mannitol. Among 13 patients evaluable for response, 2 partial responses were observed.
