Background: The aim of the study is to evaluate the results of END versus observation in the treatment of stages I and Ⅱ squamous cell carcinoma of tongue.Patients and methods: This is a retrospective study including 229 patients with surgical treatment between June 1993 and May 2010.Results: There were 15 (9.6％) patients in the END group and 14 (19.2％) patients in the observation group who developed nodal recurrence alone without associated local recurrence or distant metastasis.And node-related mortality rate was 5.1％ (8/156) for END and 12.3％ (9/73) for observation.And the further analysis for subgroups of stage T1 showed that the patients from END group can receive a better 5-year DSS than those from observation group in spite of no statistical difference (87.2％ vs.76.0％, Log-rank p=0.282).While, it is obviously found that END compared with observation for patients of stage T2 received a better 5-year DSS (74.2％ vs.41.2％, Log-rank p=0.008).
