Radiation Therapy Plus Paclitaxel in Treating Patients With Nonmetastatic, Unresectable Pancreatic Cancer

Overview

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of radiation therapy plus paclitaxel in treating patients who have nonmetastatic, unresectable pancreatic cancer.

OBJECTIVES: I. Determine the response rate of patients with nonmetastatic, unresectable pancreatic cancer receiving external beam irradiation and weekly paclitaxel. II. Determine the median survival after this treatment in these patients. III. Evaluate the acute and late treatment morbidity of paclitaxel in these patients. IV. Correlate p53 status with treatment response to this treatment in this patient population. OUTLINE: This is a open label, multicenter study. Patients are highly recommended to undergo laparoscopic surgical staging prior to protocol to exclude peritoneal and hepatic metastases. Patients receive paclitaxel IV over 3 hours weekly for 6 weeks beginning on day 1 followed 1.5 hours later by external beam radiotherapy daily 5 days a week for 5.5 weeks beginning on day 1. All patients are restaged with an abdominal CT scan 6 weeks following completion of chemoradiotherapy. If there is marked response to treatment at this time, curative surgery may be attempted at the discretion of the attending surgeon. Patients are followed every 3 months for 1 year, every 4 months for the second year, every 6 months for years 3-5, and annually thereafter. PROJECTED ACCRUAL: A total of 100 patients will be accrued into this study over 12 months.
