OBJECTIVE. Systemic chemotherapy and chemoradiotherapy, the standard treatments, do not satisfactorily improve the poor prognosis of unresectable pancreatic cancer. The authors administered arterial infusion of 5-fluorouracil (5-FU) combined with concurrent radiation therapy to enhance the antitumor effect of chemotherapy. The purpose of this study was to examine the efficacy and safety of this combined therapy.

MATERIALS AND METHODS. One or two catheters were placed into the pancreas-supplying arteries angiographically. To obtain adequate drug distribution, the positions of the catheters were determined in accordance with the results of CT during arterial injection of contrast material. A dose of 333 mg/m²/d of 5-FU was continuously infused for 5 days a week for 5 weeks, with concurrent radiation therapy (50 Gy at 2.0 Gy per fraction). Twenty patients with unresectable pancreatic cancer were enrolled in this study.

RESULTS. Of the 20 patients, 19 (95%) completed the scheduled course of this combined therapy. Fourteen patients showed a partial response (response rate, 70%). Serum cancer antigen 19-9 (CA 19-9) levels were reduced by more than 50% in 16 of 18 patients (80%). The 1-year and 3-year survival rates were 40% and 17%, respectively, with a median survival time of 11.0 months. Grade 3 or worse nonhematologic toxicity was observed in 11 patients (55%), but there were no life-threatening toxicities or complications.

CONCLUSION. Arterial infusion of 5-FU combined with concurrent radiation therapy is tolerable and can produce a high response rate with encouraging survival duration for unresectable pancreatic cancer.
