Background: The aim of this study was to determine the activity of the combination of cisplatin, gemcitabine and 5-fluorouracil (5-FU) as therapy for metastatic or locally advanced inoperable pancreatic adenocarcinoma.
Patients and methods: Patients with histologically proven advanced or metastatic pancreatic adenocarcinoma received first-line chemotherapy comprising cisplatin (20 mg/m2 on days 1, 8, 15, 22, 29 and 36), gemcitabine (1000 mg/m2 on days 1, 8, 29 and 36) and 5-FU (200 mg/m2 as continuous infusion on days 1-42) every 56 days.
Results: A total of 34 patients were studied. Eighty courses were administered (median two courses per patient). Among 32 patients evaluable for response, two patients had a complete response and four a partial response for an overall response rate of 19% (95% confidence interval 7% to 36%). Thirteen patients had stable disease (40%) and 13 progressed. Median progression-free survival was 4.7 months, median survival 9.0 months and 26% of patients achieved 1-year survival. Ten of 25 patients (40%) with pain at presentation had a sustained reduction of analgesic consumption. The principal grade 3/4 toxicities were neutropenia, thrombocytopenia, anaemia and mucositis, occurring in 24%, 21%, 9% and 3% of patients.
Conclusion: This schedule seems well tolerated and active in pancreatic cancer and worthwhile of further evaluation.
