AFP and metastasis: Age, gender, tumor marker levels (CEA, AFP and CA19-9), primary tumor size, liver metastasis lesion size, tumor emboli, ascites, T staging and N staging all had no significant correlation with survival, but the number of liver metastatic lesions (log rant test, p = 0.028, Table2, Figure2) and peritoneal metastasis (log rant test, p = 0.007, Table2, Figure3) were significantly correlated with survival.
