Abstract
Objective To analyze the risk factors of liver metastasis from gastric cancer. Methods The clinical data of 225 patients with liver metastasis from gastric cancer who had been admitted to our hospital from January 1996 to December 2001 were retrospectively analyzed. Synchronous liver metastasis was observed in 123 patients and metachronous liver metastasis in 102 patients. The risk factors of liver metastasis from gastric cancer were evaluated. Results The gender of patients, location and size of gastric cancer foci, differentiation and invasion depth of gastric cancer, Lanren classification, lymph node metastasis and lymph node metastasis in region Ⅷ, vascular invasion, extrahepatic metastasis, ascites and peritoneal metastasis were the significant factors associated with liver metastasis from gastric cancer (X2 = 43.560-263. 907, P<0.05). All the factors except the size of gastric cancer foci, extrahepatic metastasis and ascites were found to be the significant factors associated with different types of liver metastasis from gastric cancer (X2 = 6.673-26. 555, P < 0.05 ). Logistic regression analysis demonstrated that the gender of patients, lymph node metastasis and peritoneal metastasis were the factors that determined the types of liver metastasis from gastric cancer. Conclusion The gender of patients, lymph node metastasis and peritoneal metastasis are the important factors to evaluate the occurrence of different types of liver metastasis from gastric cancer. Key words: Gastric cancer; Liver metastasis
