Abstract:
Objective Liver is a common site of metastasis of gastric cancer and hitherto there has been no uniform treatment for liver metastasis of gastric cancer. This study was to investigate the clinical characteristics and prognostic factors of liver metastasis of gastric cancer in order to provide some evidence for the improvement of the diagnosis and treatment of the disease. Methods We ret-rospectively analyzed the clinical characteristics and survival data of 143 patients with liver metastasis of gastric cancer treated in our hospital between March 2007 and September 2012. We investigated the independent risk factors affecting the prognosis of the disease u-sing the Cox Regression Model. Results Seventy-five ( 52. 4%) of the 143 patients survived for 12 months, 41 ( 28. 7%) for 24 months, and 18 (12.6%) for 36 months, with a median survival time of 14 months. Univariate analysis revealed statistically significant differences in the survival time among the patients with different histological grades of primary gastric cancer, time of liver metastasis, types of metastatic liver cancer, extra-liver metastasis, and treatment methods ( P<0.05) . Multivariate Cox regression analysis showed the histological grade of gastric cancer to be low-or non-differentiation ( HR=2.67, 95% CI:1.51-4.72) and the type of liver meta-static cancer to be H2 ( HR=1.89, 95% CI:1.08-3.29) or H3 ( HR=2.13, 95% CI:1.32-3.44) , which were independent risk fac-tors affecting the prognosis of liver metastasis of gastric cancer, while palliative chemotherapy ( HR=0.55, 95% CI:0.32-0.95) was an independent protective factor of its prognosis. Conclusion Patients with liver metastasis from gastric cancer usually have a poor prognosis, especially those with histologically low-grade gastric cancer or type-H2 or -H3 liver metastatic cancer. The prognosis of thepatients undergoing palliative chemotherapy may have a better prognosis than those receiving best supportive care. A comprehensive therapy should be recommended to patients with liver metastasis from gastric cancer.
