A phase I trial of intravenous melphalan, paclitaxel, and cisplatin plus granulocyte-colony stimulating factor in patients with suboptimal advanced epithelial ovarian carcinoma or peritoneal carcinoma.

Abstract：

BACKGROUND:The primary purpose of this study was to establish the maximum tolerated dose (MTD) of intravenous melphalan in combination with paclitaxel and cisplatin plus granulocyte-colony stimulating factor (G-CSF) in patients with suboptimal advanced epithelial ovarian carcinoma or primary peritoneal carcinoma. METHODS:Patients with suboptimal (>2 cm residual tumor) Stage III or Stage IV epithelial ovarian carcinoma or peritoneal carcinoma were eligible for this Phase I study. In the first stage of the study, the doses of paclitaxel and cisplatin were fixed at 135 mg/m(2) and 75 mg/ m(2), respectively, and the dose of intravenous melphalan was escalated in consecutive cohorts of 3-6 patients depending on toxicity. The planned dose escalation levels of melphalan were 6 mg/m(2), 10 mg/m(2), and 14 mg/m(2). In the second stage of the study, the doses of cisplatin and melphalan were fixed at 75 mg/m(2) and the MTD level, respectively, and the dose of paclitaxel was escalated. The planned dose escalation levels of paclitaxel were 150 mg/m(2), 175 mg/m(2), 200 mg/m(2), 225 mg/m(2), and 250 mg/m(2). G-CSF was administered for 12-19 days with each cycle, and cycles were repeated every 4 weeks for a total of 6 cycles. Other end points included clinical or surgical response, progression free survival, and survival. RESULTS:Between January 1993 and May 1996, 34 women with untreated advanced stage epithelial ovarian carcinoma or primary peritoneal carcinoma were treated with 192 cycles of therapy. The MTD of melphalan was 10 mg/m(2), with the dose-limiting toxicity being thrombocytopenia. Paclitaxel was escalated to a dose level of 200 mg/m(2) with a toxicity rate of < 33%. The clinical response rate was 80% in 29 patients with measurable disease. Of 11 patients who underwent second-look surgery, 5 (45%) had a surgical pathologic complete response. The median progression free survival was 16.8 months and the median survival was 32.8 months. CONCLUSIONS:The combination of intravenous melphalan, paclitaxel, and cisplatin was found to have acceptable toxicity and good activity. A Phase II study of this combination appears to be warranted.
