Results of Hepatic Resection for Liver Metastasis of Gastric Cancer : A Single Center Experience

Background : Surgical indication for hepatic resection is controversial in gastric cancer liver metastasis (GLM). The aim of this study is to clarify the effect of hepatic resection for GLM. Methodology : Ten patients who underwent hepatic resection for GLM between 2001 and 2013 were enrolled in this study. Six patients underwent synchronous hepatic resection and gastrectomy, and the remaining four patients underwent metachronous hepatic resection. Six patients had solitary liver metastasis, and 4 patients had multiple liver metastasis. The median follow-up period was 12.4 months (the range being 0.5months to 50 months). Result : The actual 1- year and 3-year overall survival rates for the patients who underwent hepatic resection are 88.9% and 17.8%, respectively. The median survival time was 21.5 months. And the 1-year recurrence free survival time was 20.0%. The median recurrence free survival rate was 4.7 months. Regarding post-operative recurrence, synchronous hepatic resection tended to be a recurrence factor (p=0.08). Conclusion : Hepatic resection for GLM has an acceptable outcome. Metachronous hepatic resection tends to have a better outcome than synchronous hepatic resection for the treatment of GLM.
