 Considering the rapid and wide acceptance and use of endoscopic treatments for early gastric cancer, there is a need for more accurate histopathological evaluation of resected specimens. The following parameters must be recorded in the histopathological evaluation:tumor size(longest diameter), predominant histological type, depth of invasion, presence/absence of vascular infiltration, distribution of undifferentiated-type carcinoma, presence/absence of ulceration within the lesion, and resection margins. Furthermore, these parameters are also used as significant evidence in the evaluation of endoscopic curability. Intratumor heterogeneity is also observed during the tumor growth and progression of gastric cancer. Therefore, a meticulous histopathological examination of the endoscopically resected specimens is required.
