[Liver resection in a case of multiple liver metastases of gastric cancer following hepatic arterial infusion chemotherapy].

A 61-year-old-man underwent subtotal gastrectomy (D2) for advanced gastric cancer with multiple liver metastases. After the operation, repeated hepatic arterial infusion chemotherapy was performed employing implantable catheter and port system with CDDP and MMC. The result was that the liver tumors showed a remarkable regression in size, and the serum CA 19-9 level decreased within normal range. But the tumor in the lateral segment grew and the CA 19-9 level increased again. There was no evidence of metastasis or recurrence except in the liver, and the metastatic tumors in right lobe became smaller by hepatic arterial infusion chemotherapy at this time. Therefore, lateral segment resection was performed for reductive surgery 14 months after the first operation. After that, the liver tumors did not grow and CA 19-9 kept within the normal range, while hepatic arterial infusion chemotherapy could be given. Thus, it seems that liver resection for reduction surgery following hepatic arterial infusion chemotherapy should be considered as a treatment for multiple liver metastases.
