Fluorouracil, Gemcitabine, and Radiation Therapy in Treating Patients With Cancer of the Pancreas

Pancreatic Cancer Clinical Trial

Official title: A Phase III Study of Pre and Post Chemoradiation 5-FU vs. Pre and Post Chemoradiation Gemcitabine for Postoperative Adjuvant Treatment of Resected Pancreatic Adenocarcinoma

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known which treatment regimen is most effective for pancreatic cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of fluorouracil and gemcitabine plus radiation therapy in treating patients with cancer of the pancreas who have undergone surgery.

Clinical Trial Description

OBJECTIVES:

• Compare the overall and disease-free survival of patients with resected adenocarcinoma of the pancreas treated with adjuvant fluorouracil-based chemoradiotherapy preceded and followed by fluorouracil vs gemcitabine.

• Compare the local-regional and distant disease control in patients treated with these regimens.

• Compare the acute and late toxic effects of these regimens in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to nodal involvement (yes vs no), tumor diameter (less than 3 cm vs 3 cm or greater), and surgical margins (negative vs positive vs unknown). Patients are randomized to one of two treatment arms.

• Arm I: Beginning 3-8 weeks after definitive surgical resection, patients receive fluorouracil IV continuously for 3 weeks. Beginning 1-2 weeks later, patients receive fluorouracil IV continuously concurrently with radiotherapy 5 days a week for 5.5 weeks. Beginning 3-5 weeks after completion of chemoradiotherapy, patients receive fluorouracil IV continuously for 4 weeks every 6 weeks for 2 courses.

• Arm II: Beginning 3-8 weeks after definitive surgical resection, patients receive gemcitabine IV once weekly for 3 weeks. Beginning 1-2 weeks later, patients receive chemoradiotherapy as in arm I. Beginning 3-5 weeks after completion of chemoradiotherapy, patients receive gemcitabine IV once weekly for 3 weeks every 4 weeks for 3 courses.

Patients are followed every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 518 patients will be accrued for this study within 8.6 years. ;
