Abstract: The incidence of adenocarcinoma of the esophagogastric junction (AEG) dramatically increased in the America and Europe. Although some search results on AEG have been reported, it is still difficult to elucidate the clinical status of AEG in China. The consensus of standardized treatment of AEG is gradually formed. For early AEG, endoscopic mucosal resection, endoscopic submucosal dissection, laparoscopic surgery and minimally extent surgery were the main treatment methods; for advanced AEG, transthoracic esophagectomy or media stinal lymph node dissection can offer beneficial prognosis for patients with Siewert type Ⅰ AEG, while extended total gastrectomy, extended esophagogastrectomy, D₂ lymph node dissection are appropriate for patients with Siewert type Ⅱ and Ⅲ AEG.
