Category Diagnosis Clinical management
1.No tumor / atypical hyperplasia May not be followed up
Normal mucosa
Various gastritis or gastric diseases
Intestinal epithelial metaplasia
2.Uncertainty of neoplasia/aplasia Follow up
For reactive/regenerative or tumorigenic lesions that cannot be determined
3.Low-grade mucosal tumors Endoscopic resection or follow-up
Low-grade adenoma
Low-grade atypical hyperplasia
4. High-grade mucosal tumors Endoscopic or surgical local excision
High-grade adenoma/ atypical hyperplasia
Non-invasive carcinoma/carcinoma in situ
Suspected invasive carcinoma
Intramucosal carcinoma
5 Cancer invading the submucosa Surgical resection
The novelties of this classification are.
(1) Each category of lesion has a corresponding treatment or management method;
(2) The concept of intraepithelial tumor is introduced;
(3) High-grade atypical hyperplasia, carcinoma in situ, suspicious carcinoma, and even intra-mucosal carcinoma are grouped into one category of high-grade intra-mucosal tumors.
This is the most important feature of this classification, which can basically eliminate the differences in diagnosis between East and West.
