LN = lymph node; EGD = esophagogastroduodenoscopy; LVI = lymphovascular invasion; ESD = endoscopic submucosal dissection; LAP = lower anterior or posterior; SM = submucosa; M = mucosa; WD = well differentiated; LLC = lower lesser curvature; PD = poorly differentiated; MGC = middle greater curvature; RLN = regional lymph node; SRC = signet ring cell; MD = moderately differentiated.
