[A case of advanced gallbladder cancer with biliary tract stenosis which responded to TS-1 chemotherapy].

TS-1 is reported to be beneficial for advanced gastric cancer, but there is no report on its use for advanced gallbladder cancer. The present patient was a 64-year-old woman with advanced gallbladder cancer with severe biliary tract stenosis. The primary tumor was located in the neck of the gallbladder and peripancreatic lymph node metastasis was detected. TS-1 100 mg/day was administered orally for 21 days and CDDP 30 mg/day on days 1, 8 by drip infusion. Grade 4 neutropenia was observed in the first cycle, and TS-1 alone was used for further treatment. After 2 courses, primary tumor showed PR and lymph node metastasis had disappeared. Biliary stenosis was remarkably improved. We conclude that TS-1 might be beneficial in the treatment of advanced gallbladder cancer.
