Fluorouracil, Gemcitabine, and Radiation Therapy in Treating Patients With Cancer of the Pancreas
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.
Drug: gemcitabine hydrochloride
Radiation: radiation therapy
|Study Design:||Allocation: Randomized
Primary Purpose: Treatment
|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|
|Study Start Date:||July 1998|
|Primary Completion Date:||October 2005 (Final data collection date for primary outcome measure)|
- 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.
