BACKGROUND/AIMS: To examine the efficacy and safety of a combined modality therapy consisting of hepatic arterial infusion of 5-fluorouracil and external-beam radiotherapy in patients with advanced pancreatic carcinoma. METHODOLOGY: Hepatic arterial infusion chemotherapy consisted of 5-FU 1000mg/m2 administrated as a 5-hr continuous infusion once weekly. External-beam radiotherapy (total dose, 50Gy; 2Gy/day) was delivered to the pancreas tumor concurrently for 5-6 weeks. Seventeen patients with no distant metastases except to the liver were enrolled in this study. RESULTS: Patients received a median of 13 cycles of chemotherapy. Sixteen of 17 patients received a total radiotherapy dose of 50Gy. In one patient, treatment was discontinued after 24Gy of radiotherapy and 2 cycles of chemotherapy because of progressive disease. Nausea and vomiting were the most common types of toxicity. Grade 3 or worse toxicity was observed in 2 patients. Four patients developed gastroduodenal ulcers. Of the 16 patients, 7 (41%) showed a partial response, and 9 (53%) showed no change. The median overall survival was 4.5 months and 1-yr overall survival of 11.8% was observed. CONCLUSIONS: The combined therapy is active and well tolerated, but results in a poorer prognosis, in spite of its high initial response rate.
