Abstract

As no standard chemotherapy regimen has been established for advanced gastric cancer, this study sought to evaluate the efficacy and safety of combination chemotherapy that included paclitaxel and leucovorin (LV)-modulated infusional 5-fluorouracil (5-FU) in metastatic gastric cancer. Patients received a three-hour infusion of 175 mg/m2 of paclitaxel on day 1. A bolus of 20 mg/m2 of LV was then administered, followed by a 24-h infusion of 1,000 mg/m2 of 5-FU on days 1 through 3. The treatment cycle was repeated every 3 weeks until disease progression. Response evaluation was performed according to the RECIST criteria, with toxicity determined by NCI-CTC (version 2.0). A total of 66 patients, including 21 (31.8%) with a history of prior chemotherapy, were enrolled. Fifteen (71.4%) of the 21 patients with prior chemotherapy received prolonged infusional 5-FU. In the 56 evaluable patients (37 in the chemotherapy-naïve group and 19 in the prior chemotherapy group), tumor responses according to prior exposure to chemotherapy were as follows: 17 (45.9%) partial response (PR), 6 (16.2%) stable disease (SD) and 14 (37.8%) progressive disease (PD) in the chemotherapy-naïve group; 1 (7.1%) complete response, 3 (15.8%) PRs, 8 (42.1%) SDs and 7 (36.8%) PDs in the prior chemotherapy group. The overall median response duration was 20 weeks (range, 8-61 weeks), with a median progression-free survival of 20 weeks [95% confidence interval (CI), 13.4-26.6 weeks] and 12 weeks (95% CI, 5.7-18.3 weeks) in the chemotherapy-naïve and prior chemotherapy groups, respectively. The median overall survival was 48 weeks (95% CI, 38-58 weeks) in the chemotherapy- naïve group and 28 weeks (95% CI, 22-34 weeks) in the prior chemotherapy group. The most frequent grade III/IV toxicity was neutropenia. Non-hematological toxicity of grade III/IV was rare. Paclitaxel in combination with 5-FU/LV is clinically beneficial for patients with advanced gastric cancer and is a feasible salvage regimen for 5-FU-refractory gastric cancer patients.
