  1. ELA must lie on the surface of gastric cancer tissue.
  2. ELA must be columnar epithelium with spindle or oval nuclei.
  3. Nuclear polarity must be present in the ELA
  4. The ELA must be separated and distinguished from the surrounding nonneoplastic mucosa.

1) Characteristics and Early Diagnosis of GCAE Gut Liver 2021

Differentiated cancer types were frequently found after eradication and included characteristic endoscopic features such as reddish depression (RD). However, benign RD can be difficult to distinguish from gastric cancer because of histological alterations in the surface structures (nonneoplastic epithelium or epithelium with low-grade atypia [ELA]) as well as multiple appearances of RD. Recently, we clarified similar alterations in genetic mutations between ELA and gastric cancer, suggesting that ELA is derived from gastric cancer. Clinically, submucosal invasive cancer was frequently found in patients after eradication therapy even if they received annual endoscopic surveillance.
