 According to the 14th edition of the Japanese Classification of Gastric Carcinoma, a Group 2 biopsy diagnosis is defined as indefinite for neoplasia, including regenerative atypia, adenoma, and carcinoma. Endoscopic reexaminations are therefore necessary for the diagnosis of Group 2 gastric lesions, prior to which it is necessary to review endoscopic images and biopsy specimens, including deep cutting and immunostaining. Such reviews must be accompanied with careful discussion between endoscopists and pathologists. Furthermore, considering the pre-biopsy diagnosis using magnifying narrow band imaging for Group 2 gastric lesions in this study, ESD as a diagnostic treatment is acceptable as one of first clinical support for the gastric lesions.
