The significance of hepatic resection in liver metastasis from gastric cancer remains unclear. We reported two cases of liver metastasis from gastric cancer successfully treated by hepatectomy withdisease-free survival, and discussed whether surgical removal was effective treatment. Case 1: A 72-year-old man underwent distal gastrectomy for gastric cancer located at the antrum of the stomach (tub2, SM, ly2, v0, N2). Six months later, liver metastasis arose at S3 segment, and then treated by S3 sub-segmentectomy. The patient remains well and no sign of recurrence is evident at 36 months after hepatectomy. Case 2: A 65-year-old man underwent distal gastrectomy for gastric cancer located at the lower body of the stomach (pap-tub, SS, ly1, v0, N2). 18 months later, liver metastasis arose at S5 segment, and then treated by S5 sub-segmentectomy. The patient remains well and no sign of recurrence is evident at 62 months after hepatectomy. The number and chronology of liver metastasis among these two disease-free survivors were single and metachronous, and they had broad tumor-free margins (>10mm).<br> We concluded that liver metastasis from gastric cancer without other metastatic lesions should be indicated for hepatectomy, and that surgical removal should be recommended especially for single and metachronous cases.
