A phase II study of combination CPT-11 and docetaxel in patients with ovarian carcinoma refractory or resistant to combination paclitaxel and carboplatin
15036 Background: To investigate the efficacy and toxicity of combination irinotecan and docetaxel in patients with ovarian carcinoma refractory (not responded) or resistant (relapsed within 6 months after the last chemotherapy) to the first line chemotherapy with combination paclitaxel (175mg/m2) and carboplatin (AUC=5). Methods: 30 refractory patients and 28 resistant patients with measurable disease were treated with combination irinotecan (60 mg/m2) and docetaxel (30 mg/m2) at days 1 and 8 every 3 weeks for more than 2 courses. Results: The average number of courses administered was 2.6 for refractory cases and 3.4 for resistant cases. The average number of courses administered was 2.6 for refractory cases and 3.4 for resistant cases. Using RECIST criteria, 2/28 (7%) resistant cases responded completely, 6/30 (20%) of refractory cases and 6/28 (21%) resistant cases were responded partially. 16/30 refractory cases and 14/28 cases progressed. Grade 3–4 toxicities were leukopenia (31%) neutropenia (36%) thrombocytopenia (8%) and diarrhea (6%). Conclusions: Combination chemotherapy of CPT-11 and Docetaxel at days 1 and 8 every 3 weeks is a regimen with moderate toxicity and good compliance, and shows some response to those patients who are refractory or resistant to the first-line chemotherapy with paclitaxel and carboplatin with a response rate of 20% and 29%, respectively.
