Abstract

Based on Siewert classification, adenocarcinomas of the esophagogastric junction (AEGs) have different behaviors of perigastric-mediastinal nodal metastasis. Siewert type I AEGs have higher incidence of mediastinal nodal metastasis than those of type II or III, especially at middle-upper mediastinum. With regard to the necessity of mediastinal lymphadenectomy, theoretically, transthoracic esophagogastrectomy with complete mediastinal lymphadenectomy is suggested for Siewert type I AEGs, while transhiatal total gastrectomy with lower mediastinal and D2 perigastric lymphadenectomy is a standard surgery for type II-III AEGs. Nevertheless, the mediastinal nodal metastasis is an independent factor of poor prognosis for any type of AEG.

摘要

根据 Siewert 分类,食管胃结合部腺癌(AEG)具有不同的胃纵隔区域淋巴结转移行为。Siewert Ⅰ型 AEG 的纵隔淋巴结转移发生率高于Ⅱ型或Ⅲ型,尤其是中上部纵隔。关于纵隔淋巴结清扫的必要性,理论上,对于 Siewert Ⅰ型 AEG,建议行经胸食管胃切除术和完全纵隔淋巴结清扫术,而对于Ⅱ-Ⅲ型 AEG,标准手术为经腹贲门全胃切除术和下纵隔及 D2 胃周淋巴结清扫术。然而,纵隔淋巴结转移是任何类型 AEG 预后不良的独立因素。
