Prognosis of Endoscopic Resection in Patient with Early Gastric Cancer with Undifferentiated Type Histology

초록

Background / aims: In case of early gastric cancer (EGC) with undifferentiated type histology, which did not meet the extended criteria after endoscopic submucosal dissection (ESD), addition of surgical treatment should be recommended. In clinical practice, however, there are many patients who refuse or cannot be performed surgery due to old age and comorbidities. The aim of this study was to investigate the rate of recurrence and survival in those patients.
