 With the development of new endoscopic resection techniques such as endoscopic submucosal dissection(ESD), removal of large early gastric cancer(EGC)lesions has become possible. To clarify the long-term outcome of this treatment, 2,335 lesions in a consecutive 1,955 EGC patients were enrolled. They had been treated with endoscopic resection from January, 1999 to December, 2005, at the National Cancer Center Hospital. Clinical outcome of all patients was able to be followed.

 In the histological assessment, the curative resection rate was 78% and the non-curative resection rate was 22%. In the curative resection group among patients who had single lesions, the curative resection rate according to the guide line was 49% and the curative resection rate according to the expanded criteria was 51%. The rate of patients who underwent additional surgery among the non-curative group was 53%. Among the overall 5-year-survival-rate group the curative resection group according to the guideline, the curative resection group according to expanded criteria, and the non-curative resection group with additional surgery, there were not significant differences. Concerning the hazard ratio, the same results were recognized.

 In our study, endoscopic resection especially ESD, using expanded criteria, showed an excellent long-term outcome.
