Gastric carcinoma is one of the most common malignant tumors in the world, and the accurate diagnosis of precancerous lesions plays an important role in gastric cancer prevention. Intraepithelial neoplasia is a form of precancerous lesion of gastric cancer, and many efforts have been done to explore the relationship between gastric cancer and dysplasia. Recently, there has been much progress in the research of intraepithelial neoplasia, including genetic changes at the molecular level, the eradication of Helicobacter pylori (H. pylori), regular follow-up and endoscopic therapy. All of these will play an important role in clinical management of this condition. However, the etiological mechanism, influencing factors and malignant transformation of GIN are still unclear. Hence, further multi-center and long-term prospective studies are needed to solve these problems.
