A 51-year-old man was admitted because of Borrmann 2 type gastric cancer located in the antrum. Since he had bilateral liver metastasis, palliative gastrectomy and liver biopsy was performed. Histopathologically, the primary cancer showed poorly differentiated adenocarcinoma and the liver biopsy showed the same. This patient has been alive without sign of recurrence for more than six years after he was given 40 mg of MMC, 12.5 KE of Picibanil and 528 g of PSK postoperatively. In addition, eight similar cases, with a survival rate of more than 5 years after resection of liver metastasis, have been reported in Japan and are reviewed.
