    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 re-peated 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 neutro-penia. 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.
