ABSTRACT: Background: China is a high incidence area of esophageal cancer. Esophageal squamous cell carcinoma recurrence and mortality rates are relatively high. Recent studies show that the recurrence rate remains very high even through the implementation of lymph node expanding dissection. Methods and Results: In order to study the relationship between lymph node dissection number and survival of the patients with esophageal squamous cell carcinoma, 407 cases of esophageal cancer are selected in the First Affiliated Hospital of Xi’an Jiaotong University from January 2009 to June 2013. There were 15 cases without surgery, while the rest of the 392 patients were post-operation in follow-up. 54 patients were lost in follow-up, and the rate was 13.8%. Finally, there were 338 patients entered into our research. The median age was 58 (37 - 81), males accounted for 79%. The number of lymph node dissection is for a total of 2091, and a median of 5. Positive lymph nodes are 400, while the total positive rate is 19.1%. Conclusion: The number of lymph node dissection is divided into 3 groups that are 0 to 6, 7 to 11, 12 or more into three grades, and reduced number of lymph node dissection may prolong the survival (P
