    Abstract:
    The objective of this study was to evaluate the clinical efficacy of brachytherapy combined with external-beam radiotherapy and repeated arterial infusion chemotherapy in improving stent patency and prognosis in patients with unresectable bile duct cancer as compared with brachytherapy alone. Seventeen patients were treated. Five patients received brachytherapy alone before stent placement. Twelve patients received brachytherapy combined with external-beam radiotherapy (n=5), repeated hepatic arterial infusion chemotherapy using an implanted catheter and port (n=1), or both (n=6). Mean survival was significantly improved in the group that received combined therapy as compared with the group that received brachytherapy alone (16.2 months vs. 4.6 months, p<0.01). Although stent occlusion rates were similar in the two groups (42% vs. 40%), there was a trend towards longer stent patency in the combined therapy group than in the brachytherapy group (22 months vs. 3.6 months, p<0.2). Radiation gastritis necessitating gastrectomy developed in 1 patient who received external-beam radiotherapy at more than 50 Gy. Brachytherapy combined with external-beam radiotherapy and repeated hepatic arterial infusion chemotherapy increases survival compared with brachytherapy alone in patients with unresectable bile duct cancer.
