Advanced gastric cancer with liver metastasis effectively treated by intra-hepatic arterial infusion of 5-FU, MMC and peroral administration of 5-FU: a case report.

We have experienced a case of advanced gastric cancer with liver metastasis effectively treated by intra-hepatic arterial infusion of 5-fluorouracil (5-FU), mitomycin C (MMC) and peroral administration of 5-FU. The patient was a 48-year-old male diagnosed as having advanced gastric cancer with multiple liver metastasis in the bilateral lobes of the liver. This patient was treated by intra-hepatic arterial infusion of 5-FU (250 mg/2 days x 8 doses), MMC (20 mg x 1 dose, 6 mg/2 weeks x 6 doses) and peroral administration of 5-FU (200 mg/day). At 14 weeks later, a CT revealed that the metastatic liver tumors had disappeared. However, at 7 months after the therapy, the patient eventually died of liver and brain metastasis. These results suggested that intra-hepatic arterial infusion of 5-FU and MMC was an effective therapy for metastatic tumors in the liver, but we need to perform intra-hepatic arterial infusion using a new prolonged regimen to treat the liver metastasis.
