Core Tip
Core tip: Endoscopic submucosal dissection (ESD) has recently been practiced on a differentiated type of early gastric cancer (EGC). However, there is no clear evidence for endoscopic treatment of intramucosal poorly differentiated EGC. We carried out this retrospectively study to determine the clinicopathological factors that are predictive of lymph node metastasis in intramucosal poorly differentiated EGC, and to guide the individual application of ESD in a suitable subgroup of patients with intramucosal poorly differentiated EGC.
