Surgical strategies for adenocarcinoma of esophagogastric junction

The incidence of adenocarcinoma of esophagogastric junction (AEG) is increasing worldwide during recent decades. Surgical resection still plays the most important role in comprehensive therapy for AEG. However, due to the specifics of tumor position and biological features, there are many controversies on surgical problems inlcuding preoperative clinical classification, surgical approaches, regional lymphadenectomy and resection extension. New TNM staging defines new staging for AEG, while traditional Siewert classification is still the key  typing method to decide the surgical strategies. Compared with Siewert type I and type Ⅲ AEG, there are different resection extension for Siewert type Ⅱ AEG between western and eastern countries. Moreover, the comparison between total gastrectomy and esophageal resection for Siewert type Ⅱ AEG is needed to be evaluated further in more researches. The diagnosis and treatment of AEG in the near future will be completed through multidisciplinary team.
