BACKGROUND: Systemic chemotherapy does not satisfactorily improve the poor prognosis of pancreas and biliary tract cancer unresectable or metastatic to the liver. Intra-arterial infusion of antineoplastic agents can give higher concentrations to the tumor and slighter concentrations to the whole body, with a potential of efficacy and lower toxicity, due to the hepatic clearance. METHODS: Based on a safe and ambulatorial technique of transcutaneous arterial port implantation, this study was designed to evaluate feasibility and toxicity of 5-fluorouracil (5-FU) intra-arterial continuous infusion combined with systemic gemcitabine with dose escalation. Seventeen patients affected by pancreatic (14) or biliary tract (3) cancer received up to six cycles of treatment. Treatment consisted of intravenous gemcitabine on d 1 and 8 and intra-arterial 5-FU continuous infusion on d 1-14 every 21 d. Dose-escalation levels were 900 and 1000 mg/m2 for gemcitabine and 8, 10, 12, 15, and 17 mg/kg/d for 5-FU. Consecutive cohorts of three patients were planned at each dose level. RESULTS: Gastrointestinal toxicity (vomiting and diarrhea [3rd-4th degree] and gastritis), constituted the dose-limiting toxicity, with a maximum-tolerated dose of 1000 mg/m2 for gemcitabine and 15 mg/kg/d for 5-FU. Hematological toxicity was present in a minority of patients. No patient had acute or later complications such as arterial thrombosis related to the implanted arterial port, sclerosis cholangitis, or chemical cholecistitis. CONCLUSION: 5-Fluorouracil intra-arterial continuous infusion, combined with systemic gemcitabine, seems to be a feasible and safe regimen that could give interesting results in pancreatic cancer.
