The 5-year survival rate of such patients remains low. Definition of early esophagogastric junction cancer, resectability criteria, features of the course of the disease at early stage will be considered in this article. It has been proven that NBI-ME and NBI Dual Focus in combination with endosonography are the most accurate in the diagnosis of early esophagogastric junction cancer.
