Abstract

Purpose: To evaluate the toxicities of a Phase I study of radiation therapy with concurrent 5-fluorouracil (5FU) and low dose folinic acid in patients with locally advanced pancreatic or biliary carcinoma. Methods and Materials: Twenty-seven patients with locally advanced carcinoma of the pancreas (n = 19), bile duct (n = 7), and gall bladder (n = 1) were entered into a Phase I study of combined radiation therapy, 5FU, and folinic acid. Radiation was given as a split course of 40 Gy in 20 daily fractions with a gap of 2 weeks after 20 Gy. 5-Fluorouracil, 300 to 375 mg/m2/day and folinic acid, 20 mg/m2/day were given as an i.v. bolus daily for 5 days beginning on day 1 and again on day 29. Results: Eight patients developed Grade 3 or 4 toxicities (National Cancer Institute common toxicity criteria) including nausea and vomiting (n = 4), oral mucositis (n = 4), myelosuppression (n = 2), infection (n = 2), and diarrhea (n = 1). Four patients did not complete the planned protocol due to treatment toxicities. There were two treatment deaths secondary to septic neutropenia. Treatment toxicity appeared to be related to age (> 70), performance status (ECOG = 2), and 5FU dose (> 350 mg/m2/day). Conclusion: This protocol is poorly tolerated by elderly patients or those with poor performance status, and 350 mg/m2/day is our recommended dose for 5FU as given in this protocol.
