ABSTRACT

T2 esophageal cancer refers to the invasion of esophageal tumors into the esophageal muscularis propria , of which staging, treatment and prognosis are more general and controversial than other stages of esophageal cancer .Although the TNM staging system for esophageal cancer has been continuously improved , T2 esophageal cancer has not been further subclas-sified.The accuracy of the current staging method has also been questioned.Accurate staging has important significance for the treatment of T2 esophageal cancer and prognosis.Although treatment has improved significantly in recent years , from surgery a-lone to surgery-based comprehensive treatment, from postoperative chemotherapy to preoperative neoadjuvant treatment, the treatment of T2 esophageal cancer is still inconclusive.Accurate staging and proper treatment have a significant impact on the prognosis of T2 esophageal cancer.In recent years, studies on T2 esophageal cancer have progressed rapidly, and the content of research has become more and more profound.This article reviews the research progress on the staging, treatment and prognosis of T2 esophageal cancer, providing reference for further improving the accuracy of T2 stage esophageal cancer staging, the scien-tific treatment plan and prognosis.
