食管胃结合部腺癌淋巴结清扫策略

Lymph node dissection strategy of adenocarcinoma of esophagogastric junction

食管胃结合部腺癌(AEG)的发病率呈上升趋势。AEG生长部位及生物学行为特殊,越来越多的学者认为其是一种不同于食管癌、胃癌而相对独立的疾病。AEG在解剖上位于食管和胃连接部位,其淋巴结可向纵隔和腹部两个方向转移。目前AEG的淋巴结转移规律尚不完全明确,其淋巴结清扫范围亦未达成共识。笔者针对AEG淋巴结清扫的热点问题及AEG淋巴结清扫的临床证据进行梳理和总结,旨在为临床上更合理地进行AEG淋巴结清扫提供参考。

The incidence of adenocarcinoma of esophagogastric junction[AEG]is on the rise.Due to its special lesion location and biological behavior,AEG is considered as a relatively independent disease by more and more scholars,which is different from esophageal cancer or gastric cancer.AEG is anatomically located at the junction of esophagus and stomach.The lymph node metastasis of AEG can be directed to the mediastinal and abdominal.At present,the rule of lymph node metastasis of AEG is not completely clear,and the scope of lymph node dissection has not reached a consensus.The authors summarize the hot issues and clinical evidence of lymph node dissection for AEG,in order to provide references for more reasonable lymph node dissection of AEG.
