title: Phase II study of paclitaxel and carboplatin in patients with advanced gastric cancer.
abstract: 5-Fluorouracil-based combination chemotherapy is commonly used in patients with advanced gastric cancer, but results with such therapy are fairly modest. Evaluation of newer agents is therefore required in this disease. Paclitaxel has shown promising activity as a single agent in gastric cancer. In vitro, paclitaxel exhibits sequence-dependent synergy with platinum compounds against gastric cancer. This study was conducted to evaluate the efficacy and toxicity of combination carboplatin and paclitaxel in patients with advanced gastric cancer. Twenty-seven patients with measurable or evaluable advanced gastric cancer were enrolled on the study from April 1996 to July 2000. Patients were treated with paclitaxel 200 mg/m intravenously during 3 hours followed by carboplatin at projected area under the curve 5 mg x h x ml (as per the Calvert formula). Twenty-six patients were assessable for toxicity, and 25 patients were assessable for objective response. Nine of the 27 enrolled patients had a major response for an objective response rate of 33% (95% CI 0.17-0.54) by intention-to-treat analysis. The median response duration was 4.9 months (95% CI 2.8-7.3), and median survival was 7.5 months. The 1-year survival rate was 23%. One hundred seventeen courses were administered with a median of four courses per patient administered. The major toxicity was neutropenia, with grade III to IV neutropenia observed in 9 patients (33%) and neutropenic fever in only 1 patient. Grade III peripheral neuropathy developed in two patients, and grade III myalgia and grade III fatigue developed in one patient each. There were no treatment-related deaths. The combination of carboplatin and paclitaxel is a highly tolerable, regimen with activity comparable to that of other regimens in advanced gastric cancer. This regimen needs to be further evaluated in combination with other agents and as a component of multimodality therapy in gastric cancer.
