 Established in 2009, the NICE classification(NBI international colorectal endoscopic classification)is a simple, globally utilized non-magnified NBI classification comprising of three categories, Type 1:hyperplastic polyps, including SSPs, Type 2:adenoma-superficial submucosal adenocarcinoma and Type 3:Deep submucosal invasive cancer. The JNET classification(Japan NBI expert classification)was developed in 2014 to unify the four co-existing, magnified NBI classifications(Sano, Hiroshima, Showa and Jikei classifications)to three categories. Type 1 and 3 in the JNET and NICE classifications both correspond to hyperplastic polyps and deep submucosal invasive cancer respectively. In contrast to the NICE classification, Type 2 in the JNET classification was subdivided into Type 2A:adenoma, polypectomy with acceptable piecemeal resection and Type 2B:high grade dysplasia-superficial submucosal adenocarcinoma, EMR or ESD with en bloc resection is necessary. Although the methodology adopted to create this new classification was similar to that adopted to create the NICE classification, JNET classification has evolved further and allows endoscopists to select an appropriate treatment strategy for treating colorectal lesions.
