[Interpretation of Chinese expert consensus on mediastinal lymph node dissection in esophagectomy for esophageal cancer (2017 edition): base on number or grouping of lymph node].

The Esophageal Cancer Committee of the Chinese Anti-Cancer Association have released 《Chinese expert consensus on mediastinal lymph node dissection in esophagectomy for esophageal cancer (2017 edition)》. This consensus provides guidance to standardize mediastinal lymph node dissection in esophagectomy for esophageal cancer in China, and represents the first Chinese version of naming and grouping mediastinal lymph nodes for esophageal cancer. However, controversies exist in N staging. The aim of this article is to discuss whether N staging should base on the number of lymph node metastases, or base on the region in which the metastatic lymph nodes are located.2017年中国抗癌协会食管癌专业委员会发布了《食管癌根治术胸部淋巴结清扫中国专家共识(2017版)》，是国内最先发表的关于食管癌胸部淋巴结清扫的规范化指导意见，对胸部淋巴结清扫数目和分组进行了详细的说明和推荐。文章主要针对食管癌胸部区域淋巴结清扫中，应以淋巴结分组还是个数为标准这一争议问题，对共识做出解读，以期为食管癌根治术中胸部淋巴结清扫的标准提供参考。.
