 Determination of the depth of gastric cancer invasion using contrast-enhanced endoscopy(indigo carmine dye)depends on the observation of macroscopic appearance, size, surface appearance, appearance of surrounding mucosa, and thickness. Changing the air during endoscopic observation allows easier determination of the depth of tumor invasion. Size is an important factor for determining the depth of tumor in elevated lesions. Elevated(Type 0-I)tumors, 20mm or smaller in size, are most likely intramucosal cancers. Superficial elevated(Type 0-IIa)cancers are similar to intramucosal cancers. However, when Type 0-IIa cancers have irregular nodules, submucosal tumor-like marginal elevation, central depression or ulceration, there is the possibility of submucosal invasion. In superficial depressed(Type 0-IIc)cancers, the characteristic findings of submucosal cancer comprise deep depressions, central nodules in the depressions, and submucosal tumor-like elevations. For excavated or scarred[Type 0-III or 0-IIc, UL(+)] cancers with fold convergence, clubbing or fusion of the folds are characteristic findings of submucosal invasion.
