    Abstract:
    This article describes our experience with high-dose radiotherapy in combination with the placement of expandable metallic stents (EMS) in the management of hilar bile duct carcinoma. Between 1988 and 1999, 107 consecutive patients with hilar bile duct carcinoma were treated with EMS placement either alone or in combination with high-dose radiotherapy. External beam radiotherapy (EBRT) was indicated in 101 patients, and in 86 this was combined with intraluminal 192Ir irradiation (ILRT, 59-98Gy). EMS were placed after the completion of radiotherapy. The 1-, 2-, 3-, and 5-year actuarial survival rates for the radiotherapy group were 66.4%, 23.4%, 15.6%, 7.8%, respectively, and the 1- and 2-year actuarial survival rates for the nonradiotherapy group were 66.4% and 0%, respectively. The placement of EMS was useful for the early establishment of an internal bile passage in radically irradiated patients and the 1-, 2-, 3-, and 5-year actuarial patency rates for the radiotherapy group were 56.3%, 45.3%, 35.2%, and 23.4%, respectively, and the 1- and 2-year actuarial patency rates for the non radiotherapy group were 50.0% and 0% respectively. High-dose radiotherapy, consisting of ILRT and EBRT, appears to be feasible in the management of hilar bile duct carcinoma, and it offers a survival advantage for patients not suited for surgical resection. The placement of EMS assists the internal bile flow and lengthens survival after high-dose radiotherapy.
