Objective: To evaluate the efficacy and toxicity of a biweekly DOF regimen consisting of docetaxel, oxaliplatin, 5-fluorouracil and leucovorin for advanced gastric cancer.
Methods: The biweekly DOF regimen was administered in 37 advanced gastric cancer patients. Docetaxel, oxaliplatin and leucovorin were given intravenously at a dose of 35 mg/m2, 85 mg/m2 and 200 mg/m2 for 1 h, 2 h and 2 h on D1, respectively, and 5-Fu was administered as continuous intravenous infusion for 48 h at a dose of 1500 mg/m2 on D1 and D2. This regimen was repeated every 2 weeks. The efficacy and toxicity were evaluated after completion of 3 cycles at least.
Results: The overall response rate (RR) of this series was 67.6%, complete response rate and partial response rate were 27.0% and 40.5%, respectively. The time to progression (TTP) was 9.2 months, and median survival time (MST) was 13.7 months. The RRs of 11 chemotherpy-naïve patients and 26 patients pre-treated with chemotherapy were 81.8% and 61.5%, respectively.
Conclusion: Our preliminary results showed that this biweekly combination regimen of docetaxel, oxaliplatin, 5-fluorouracil and leucovorin is effective and tolerable for advanced gastric cancer. However, further investigation of this regimen is mandatory.
