Gemcitabine With or Without Combination Chemotherapy and Radiation Therapy in Treating Patients With Nonmetastatic Pancreatic Cancer That Cannot Be Removed By Surgery

Pancreatic Cancer Clinical Trial

Official title: Non Resectable But Non Metastatic Adenocarcinoma of the Exocrine Pancreas Non Resecables. Randomised Phase III: Initial Radiochimiotherapy (5-FU, Cisplatine, 60 GY Radiotherapy) Followed by Gemcitabine Versus Gemcitabine Alone

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as gemcitabine, fluorouracil, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving more than one drug (combination chemotherapy) together with radiation therapy may kill more tumor cells. It is not yet known which treatment regimen is more effective for pancreatic cancer.

PURPOSE: This randomized phase III trial is studying gemcitabine, fluorouracil, cisplatin, and radiation therapy to see how well they work compared to gemcitabine alone in treating patients with nonmetastatic pancreatic cancer that cannot be removed by surgery.

Clinical Trial Description

OBJECTIVES:

Primary

• Compare the overall survival of patients with nonresectable, nonmetastatic adenocarcinoma of the pancreas treated with gemcitabine hydrochloride with vs without fluorouracil, cisplatin, and radiotherapy followed by gemcitabine hydrochloride.

Secondary

• Compare the toxicities of these regimens in these patients.

• Compare the objective response (complete, partial, or stable) in patients treated with these regimens.

• Compare the clinical benefit, in terms of general condition and weight maintenance in patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to WHO performance status (0 or 1 vs 2), initial treatment (laparotomy with or without bilio-digestive diversion) (yes vs no), and peritoneal cytology (positive vs negative). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive cisplatin IV over 15 minutes on days 1-5 and 29-33 and fluorouracil IV continuously on days 1-40. Patients also undergo radiotherapy daily, 5 days a week, for 6 weeks.

• Arm II: Patients receive gemcitabine hydrochloride IV over 15 minutes on day 1. Treatment repeats every 7 days for 7 weeks.

Beginning in week 11 of arm I or week 9 of arm II, patients receive gemcitabine hydrochloride IV over 15 minutes on days 1, 8, and 15. Treatment repeats every 4 weeks for up to 10 courses in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed periodically.

PROJECTED ACCRUAL: A total of 190 patients will be accrued for this trial. ;
