Oxaliplatin as First-Line Treatment in Inoperable Biliary Tract Carcinoma

Background: A multicenter phase II study was conducted in order to evaluate the efficacy and safety of oxaliplatin as first-line treatment of patients with locally advanced or metastatic carcinoma of the biliary tract. Patients and Methods: Twenty-nine chemo-naïve patients with locally advanced or metastatic biliary tract carcinoma received oxaliplatin 130 mg/m 2 i.v. every 21 days. Patients were treated until tumor progression or unacceptable toxicity. Results: An objective response (3 complete responses, 3 partial responses) was achieved in 6 patients (20.6%, 95% CI 5.95–35.4). Disease control (complete response, partial response and stable disease) was observed in 14 patients (48.2%). The median time to tumor progression was 3 months (range 0.7–39) and the median overall survival was 7 months (range 1–39). The 1-year survival rate was 32%. Toxicity was mild. Conclusion: Oxaliplatin is an active agent against biliary tract carcinoma and therefore should be further investigated in combination with other cytotoxic drugs.
