Long-term Survival after Gastric Cancer with Liver Metastasis: A Report of Two Cases

We have experienced two cases of long-term survival after surgery for gastric cancer case with liver metastasis. One case was of a 66-year-old male patient diagnosed as having type 1 advanced gastric cancer located in the posterior wall of the lower body with liver metastasis. The stage of this case was POH1 N1T2M0 stage IV. This patient underwent distal gastrectomy with D2 lymph node resection, partial hepatectomy of the S3 region including the metastatic liver tumor and coagulation of metastatic liver tumors in the S6 and S7 regions. This patient was treated by intrahepatic arterial infusion of 5-FU, CDDP and peroral administration of UFT after surgery. This patient has died at 3 years and 7 months after surgery. The other case was of a 55-year-old male patient diagnosed as having type 2 advanced gastric cancer located in the lesser curvature of the cardia with liver metastasis. The stage of this case was POH1N1T3 M0 stage IV. This patient underwent total gastrectomy with D2 lymph node dissection, wedge resection of the S8 region including the metastatic liver tumor and coagulation of a metastatic liver tumor in the S4 region. This patient was treated by obstruction of the hepatic artery using coils, peroral administration of UFT, lentinan, MMC, and continuous low-dosage 5-FU and CDDP after surgery. This patient has died at 3 years and 6 months after surgery. These results suggest that for long-term survival in cases of gastric cancer with liver metastasis, hepatectomy or coagulation of the metastatic tumor with postoperative chemotherapy are indicated in cases that have no non-curative factors and only a few metastatic tumors.
