IPCL pattern classification, which was introduced by Inoue et al. in 2001. Most of IPCL type I to III is corresponding to benign pathology including inflammation and low grade neoplasia (LGN). Approximately 50% of IPCL type IV is corresponding to LGN, and the rest is corresponding to malignant pathology including high grade neoplasia (HGN). IPCL type V is a malignant pattern and subclassified into 4 categories. V1 and V2 could be removed by endoscopic resection (ER) such as EMR and ESD. IPCL type V3 includes m3 and sm1 cancers. IPCL type Vn is a pattern for massively submucosally invasive cancers. *CRT: chemoradiotherapy.
