目的 总结食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction,AEG)淋巴结转移规律及清扫价值,以期有助于对不同AEG患者制定适宜的个性化淋巴结清扫策略.方法 检索近年来国内外关于AEG淋巴结转移情况及清扫价值的报道,进行归纳总结.结果 AEG的淋巴结转移率较高的站点包括No.l、No.2、No.3、No.7组淋巴结等,淋巴结转移率较高的站点往往清扫的获益也较大.淋巴结转移与肿瘤大小、肿瘤位置等因素有关,个别站点的淋巴结清扫仍存在争议.结论 AEG的淋巴结清扫范围争议颇多,尤其是SiewertⅡ型AEG的淋巴结清扫范围,仍需要前瞻性多中心研究的证明.
Research updates on lymph node metastasis and dissection value in adenocarcinoma of the esophagogastric junction
Objective To review the lymph node metastasis pattern and its dissection value among adenocarcinoma of the esophagogastric junction(AEG)patients,in order to assist suitable individualized lymph node dissection strategies for diverse AEG patients.Methods The reports about lymph node metastasis and the value of dissection of AEG worldwide in recent years were retrieved and summarized.Results The sites with higher lymph node metastasis rate of AEG included No.1,No.2,No.3,No.7 lymph nodes,etc.and sites with higher lymph node metastasis rate often benefit from dissection.Lymph node metastasis was related to factors such as tumor size and location,and lymph node dissection at individual sites is still controversial.Conclusion The lymph node dissection range of AEG is highly controversial,especially for Siewert type Ⅱ AEG,which still requires prospective multicenter studies to prove.
