Ten patients with liver metastases from advanced gastric cancer received percutaneous ethanol injection therapy (PEI) and chemotherapy by hepatic arterial infusion (HAI) via implantable reservoir. A 90% ethanol solution including 10%. Lipiodol was injected in the liver as PEI.5-FU, EPIR and MMC were used as the regimen for HAI chemotherapy. We have performed this therapy (PEI + HAI) for ten patients with liver metastases since February, 1997. These patients have received this therapy for 4-36 months and three patients died within 16 months. However, three patients did not develop any liver failure after this therapy. The median survival rate was 25.2 months. There are statistically significant differences between upto ss and over se of invasion, and between INF alpha and gamma (p = 0.005).
