Gemcitabine combined with 5-fluorouracil and cisplatin (GFP) in patients with advanced biliary tree cancers: a pilot study.
BACKGROUND: Advanced biliary tree cancers have poor prognosis and chemotherapy has been shown to have little impact. To date, no standard chemotherapy regimens have been established. A pilot study to evaluate gemcitabine/5-Fluorouracil(5-FU)/cisplatin(CDDP) (GFP) chemotherapy in patients with advanced biliary tree cancers was performed. PATIENTS AND METHODS: Eight patients with advanced intrahepatic cholangiocarcinoma and gallbladder carcinoma with no prior chemotherapy were treated with a 4-week cycle GFP chemotherapy consisting of gemcitabine at 1000 mg/m2 on days 1, 8, and 15, and of 5-FU at 250 mg/patient and CDDP at 5 mg/patient on days 1 to 5, 8 to 12 and 22 to 26. RESULTS: Of these 8 patients, no complete responses (CR) were observed, but 3 patients (37.5%) demonstrated partial responses (PR) with an additional 3 patients (37.5%) having stable diseases (SD), as assessed by RECIST. Two patients with PR and 1 patient with SD were treated by curative operation after GFP chemotherapy and all of them survived with no recurrence. The median overall survival time was 23.5 months, and median time to progression was 14.5 months. Grade 3/4 side-effects, such as leukopenia, thrombocytepenia and anemia were found in 4 patients (50%), but no patients dropped out because of toxicity. CONCLUSION: This GFP chemotherapy has promising antitumor activity and is well tolerated in patients with advanced biliary tree cancers. This regimen warrants further evaluation in a phase II study including larger numbers of patients.
