Ref. | Endoscopic technique | Differentiated-type EGC (D-EGC) | Undifferentiated-type EGC (UD-EGC) |
Nakayoshi et al[161] | NBI-ME | Relatively regular fine network pattern | Relatively irregular, twisting or corkscrew pattern, with a relatively low density of microvessels |
Endo et al[162] | NBI-ME | Grid network pattern with hypervascularity | Short twig or branch-like pattern with hypovascularity |
Tamai et al[163] | NBI-ME describing depressed gastric adenomas vs protruding adenomas | Intramucosal 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-ME | WOSa 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-ME | Amongst 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 pattern | In 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 |
