Table 2 Gastric cancer differentiation using narrow-band imaging with or without magnification
Ref.Endoscopic techniqueDifferentiated-type EGC (D-EGC)Undifferentiated-type EGC (UD-EGC)
Nakayoshi et al[161]NBI-MERelatively regular fine network patternRelatively irregular, twisting or corkscrew pattern, with a relatively low density of microvessels
Endo et al[162]NBI-MEGrid network pattern with hypervascularityShort twig or branch-like pattern with hypovascularity
Tamai et al[163]NBI-ME describing depressed gastric adenomas vs protruding adenomasIntramucosal carcinomas were more frequently found in depressed adenomas (reddish in color, a regular ultrafine network pattern of mucosal microvasculature) (25%) than in protruding adenomas (4.5%)
Yao et al[164]NBI-MEWOSa white substance within the neoplastic epithelium that may obscure the subepithelial microvascular pattern. More frequent in non-advanced neoplasia than in advanced carcinomas and that 100% of non- advanced lesions demonstrated a regular distribution of WOS
Yokoyama et al[165]NBI-MEAmongst the D-EGC lesions, fine-network pattern, intra-lobular loop pattern-1, intra-lobular loop pattern-2 and corkscrew pattern were observed in 15.7%, 59.6%, 24.2% and 0.5%, respectively. D-EGCs mainly exhibited fine-network pattern or intra-lobular loop patternIn UD-EGC intra-lobular loop pattern-2 and corkscrew pattern were observed in 41.2% and 58.8%, respectively. Therefore, UD-EGCs were all classified as intra-lobular loop pattern-2 and corkscrew pattern
