PURPOSE: We conducted a phase II trial of 5-fluorouracil and oxaliplatin combination chemotherapy as a second-line treatment in unresectable/metastatic biliary tract cancer patients who had failed gemcitabine-based chemotherapy. METHODS: Patients treated with gemcitabine-based palliative treatment were enrolled in this study. Patients were received modified FOLFOX3 (mFOLFOX3) consists of oxaliplatin 85 mg/m(2) (day 1) and leucovorin 30 mg (days 1, 2) followed by 5-fluorouracil 1,500 mg/m(2) (days 1, 2) every 2 weeks. RESULTS: Between March 2010 and June 2012, a total of 30 patients were enrolled in this study. Twenty-eight patients were measurable for treatment response. One achieved complete response, and one a partial response was observed. Overall response rate was 7.1% (95% confidence interval 0.9-23.5%). The median progression-free survival was 1.6 months, and the median overall survival was 4.4 months. Grade 3-4 hematologic toxicities included neutropenia (6.7%) and thrombocytopenia (3.4%). The most common non-hematologic toxicity was neuropathy (22.2%). However, the most common grade 3-4 non-hematologic toxicity was hyperbilirubinemia (5.0%). There was one treatment-related death due to neutropenic infection. CONCLUSION: mFOLFOX3 as a second-line regimen has modest effect and tolerable toxicity in unresectable/metastatic biliary tract cancer patients who have been treated previously via gemcitabine-based chemotherapy.
