作者用CT评价手术病理证实的97例非小细胞性肺癌的纵隔淋巴结。男84,女13例;年龄33～77岁。其中23例(鳞癌15、腺癌5、大细胞性肺癌2、恶性类癌1例)有纵隔淋巴结转移。根据美国胸部学会提出的纵隔淋巴结分区确定14例有一个区淋巴结受累,9例至少有两个区。共累及37个区。作者认为通常肿瘤转移到纵隔淋巴结途径,在右肺和左上叶多播散到同侧纵隔淋巴结,左下叶不仅同侧受累也向对侧淋巴结转移。两肺肿瘤均可转移到锁骨上、颈深淋巴链和腹主动脉旁淋巴结。为判断是否有淋巴结转移,作者确定4组来观察。Ⅰ组:癌瘤引流区淋巴结短轴≥10mm,与其它引流区最
The authors used CT to evaluate the mediastinal lymph nodes of 97 non-small cell lung cancers confirmed by pathology. Male 84, female 13 cases; aged 33 to 77 years old. Among them, 23 cases (squamous cell carcinoma 15, adenocarcinoma 5, large cell lung cancer 2, and malignant carcinoid 1 case) had mediastinal lymph node metastasis. According to the division of mediastinal lymph nodes proposed by the American Thoracic Society, 14 cases had a regional lymph node involvement and 9 cases had at least two areas. A total of 37 districts were involved. The authors believe that usually the tumor metastasizes to the mediastinal lymph node pathway and spreads to the ipsilateral mediastinal lymph nodes in the right lung and left upper lobe, and the left lower lobe is not only ipsilateral but also to the contralateral lymph nodes. Both lung tumors can metastasize to the supraclavicular, deep cervical lymph nodes and paraaortic lymph nodes. To determine whether there is lymph node metastasis, the authors identified 4 groups to observe. Group I: The short axis of the lymph node in the drainage area of the cancer ≥10 mm, and most of the other drainage areas
