[Two cases of successful local control with intermittent hepatic arterial infusion therapy using 5-FU and external radiation therapy for unresectable advanced gall bladder cancer].

Unresectable advanced gall bladder cancer has a very poor prognosis. No good chemotherapeutic regimen is available. We report two cases of unresectable advanced gall bladder cancer patients who received the combination of intermittent hepatic arterial infusion chemotherapy and external radiation therapy. A 45-year-old male was alive for 576 days, and a 69-year-old male was alive for 246 days after the first diagnosis. They have been able to maintain a good quality of life without any severe adverse effects.
