Purpose We retrospectively determined the efficacy and safety of the combination of oxaliplatin, 5-fluorouracil (5-FU), and folinic acid (FA) as first-line chemotherapy for patients with metastatic or recurrent gastric cancer. Materials and Methods Between January 2006 and August 2009, 39 patients with histologically-confirmed, metastatic or recurrent gastric cancer underwent chemotherapy, and the results were retrospectively investigated. The chemotherapy regimen consisted of oxaliplatin (100 mg/m2)and FA (200 mg/m2; 2-hour infusion), then 5-FU (2,400 mg/m2; 46-hour continuous infusion)every 2 weeks. Results Thirty-nine patients received a total of 210 treatment cycles. The median number of cycles was 6 (range, 1 to 16). Of the 32 evaluable patients, zero patients achieved a complete response and 11 patients achieved a partial response (response rate, 28.2%). The median timeto-progression and overall survival were 4.3 months (95% confidence interval [CI], 2.0 to 6.5months) and 9.8 months (95% CI, 3.5 to 16.0 months), respectively. The main hematologic toxicity was anemia, which was observed in 119 cycles (56.7%). Grade 3/4 neutropenia was observed in 32 cycles (15.2%). The main non-hematologic toxicity was constipation, which was observed in 91 cycles (46.2%). Peripheral neuropathy occurred in 71 cycles (33.8%); all cases were grade 1 or 2. No treatment-related deaths were reported. Conclusion This study showed that combination chemotherapy with oxaliplatin, 5-FU, and FA is an active and well-tolerated regimen as first-line treatment in patients with metastatic or recurrent gastric cancer.
