[Response in a case of inoperable bile duct cancer treated by combined chemotherapy of S-1 and gemcitabine].

A 60-year-old male patient was diagnosed as bile duct cancer with left neck and abdominal para-aortic lymph node metastasis. He was treated by combined chemotherapy of S-1 and gemcitabine(GEM). S-1 (120 mg/day) was administered 14 days followed by 14 days rest as one course. GEM (1,000 mg/m2) was administered at 8 and 15 days after the start of S-1. Combined therapy could be continued, though S-1 and GEM were reduced for neutropemia. After 5 courses of treatment, CT and MRCP revealed a partial response. S-1/GEM combined therapy was effective for inoperable biliary tract carcinoma.
