 We investigated 304 early gastric cancers that underwent ESD(endoscopic submucosal dissection)or operation at our hospital from the viewpoint of the macroscopic type, the size and depth of cancer using conventional and dying endoscopy and resected specimens. Among 166 early gastric cancers treated by ESD, the size of the lesion is significantly larger in SM2 invaded cancers than in M-SM1 invaded cancers in type 0-IIc group. Among all the early gastric cancers regardless of treatment procedure, the size of the lesion is significantly larger in SM2 invaded cancers than in M-SM1 invaded cancers in the type 0-IIc UL(-)group. The size of the lesion may be one of the factors to distinguish M-SM1 from SM2 in type 0-IIc UL(-)gastric cancer. SM2 invaded cancers existed 4.3% of cases with conventional indication for ESD, and 6~7% in differentiated-type cancers of extended indication for ESD. The characteristic endoscopic findings of SM2 invaded cancer are important as well as the size and the macroscopic type for correct diagnosis.
