Gastric cancer liver metastasis: Optimal management for oligo-metastatic disease.

Abstract

136Background: The role of surgery for gastric cancer liver metastasis (GCLM) has not been established and particularly, the optimal management for liver-isolated, oligo-GCLMs remains controversial. The aims of this study were to review the outcomes for our patients with GCLM who underwent liver resection and to define the optimal selection criteria for resection. Methods: The medical records of patients who underwent liver resection for GCLMs with curative intent at our institution from 1993 through 2018 were reviewed. Our criteria for liver resection included absence of extrahepatic disease, and the limited number of liver metastasis (often 3 or less). Results: Total 101 patients with GCLM (77 men [76%], median age 66 years) were included. Forty-seven patients (46%) had synchronous metastasis and all underwent simultaneous resection with the primary disease. Those with synchronous disease received neoadjuvant therapy more often than those with metachronous disease (63% vs 37%, p = 0.021). Median RFS and...
