En bloc resection and en bloc with R0 resection rates in MUC-EGC cases were 94.1 % and 81.7 %, respectively. MUC-EGC was significantly associated with larger tumor size, more frequent submucosal invasion, and lymphovascular invasion compared to PuD-EGC. Despite these aggressive features of MUC-EGC, no lymph node metastasis or extragastric recurrence occurred during follow-up after ESD if MUC-EGC met the curative endoscopic resection (ER) criteria for tumors of absolute or expanded indications.
