The patient was a 68-year-old woman who visited a nearby clinic with a chief complaint of right hypochondrial pain. A mass lesion in the gallbladder was found by ultrasonography. She was referred to our hospital for further examination and was diagnosed with gallbladder cancer. Cholecystectomy and bile duct resection were performed. Six months after the surgery, multiple liver metastases were found. A subcutaneous implant reservoir was placed in the hepatic artery from the right femoral artery. After arterial infusion chemotherapy by 5-FU and CDDP, or 5-FU alone, liver metastasis markedly responded and became undetectable, and therapy was therefore discontinued. The patient has been disease-free without any sign of recurrence for 7 months after CR was achieved. It is suggested that arterial infusion chemotherapy is useful and safe for the treatment of liver metastasis from gallbladder cancer.
