Analysis of the prognostic factors for liver metastasis of gastric cancer after hepatic resection: a multi-institutional study of the indications for resection.

Abstract

Hepatic resection for liver metastasis should be attempted in case primary gastric cancer has neither lymphatic invasion nor venous invasion. The most common recurrent site was the liver. In patients with advanced gastric cancer, having neither serosal invasion nor lymph node metastasis, who underwent a less curative operation, the intra-hepatic recurrence would be expected. Thus, aggressive adjuvant chemotherapy through the hepatic artery may improve the survival after hepatectomy in these patients.
