BACKGROUND: To increase the options for agents for gastric cancer chemotherapy, we performed a phase II clinical trial on the use of a 3-h infusion of paclitaxel to confirm its efficacy and the feasibility of its use in patients with advanced gastric cancer. METHODS: Thirty-two (32) patients with measurable metastatic gastric cancer were enrolled in this study. Seventeen patients (53%) had received prior chemotherapy for metastatic disease, 4 patients (13%) had adjuvant chemotherapy alone, and 11 patients (34%) were chemotherapy-naive. Paclitaxel was intravenously infused for 3 h, at a dose of 210 mg/m(2), once every 3 weeks. To prevent hypersensitivity reactions, standard premedication was administered to all patients. RESULTS: Nine (28%; 9/32 ) objective partial responses (PRs) were observed (95% confidence interval [CI], 14%-47%), and the remaining 23 patients showed stable (12 patients; 37.5%) and progressive disease (11 patients; 34.4%). The median time to response was 20 days (range, 14-38 days). The median response duration was 87 days (range, 50-103 days). The median survival of all patients was 234 days (range, 13-646+ days). The major adverse reactions were myelosuppression (grade 3/4 leukopenia and neutropenia were observed in 59% and 88% of the patients, respectively), alopecia, and peripheral neuropathy. Peripheral neuropathy was observed in 19 patients, however, most of the patients recovered after the completion of treatment. CONCLUSION: A 3-h infusion of paclitaxel is an effective therapy for advanced gastric cancer and is clinically well tolerated by the patients.
