Objective: To investigate the features of the preoperative clinicopathologic characteristics in correlation with lymph node metastasis. Methods: The preoperative clinicopathologic characteristics and lymph node metastasis of 265 patients with early gastric carcinoma were analyzed retrospectively. Results: The three clinicopathologic characteristics, maximum cancer diameter ＞2cm under endoscope, poor differentiation and excavated type were significant high risk independent preoperative clinicopathologic characteristics(P＜0.05). The patients who had none of the three preoperative clinicopathologic characteristics had no lymph node metastasis, while 27.27% of the patients who had all the three preoperative clinicopathologic characteristics had N2 lymph node metastasis. Conclusion: The three preoperative clinicopathologic characteristics, maximum cancer diameter under endoscope, cell differentiation and gross type were very useful to evaluate the extent of lymph node metastasis.
