肺癌有纵隔淋巴结转移者预后差,有人建议纵隔淋巴结转移者属手术禁忌。在CaHens(1959)介绍纵隔镜检以前,尚无可靠的方法在术前了解纵隔情况。pearson等和Fizhmen报告常规作纵隔镜检阴性者切除率达85～95%。1982年8月至1984年5月作者对41例经纵隔镜或/和开胸诊断为肺癌的病例同时作CT,以了解可能有的纵隔淋巴肿大。CT每1cm断一层,淋巴结>lcm直径者为阳性,按美国癌症协会TNM分期,并和手术病理分期怍比较。1期27例CT纵隔正常,其中8例为孤立结节,
The prognosis of lung cancer with mediastinal lymph node metastasis is poor, and it has been suggested that mediastinal lymph node metastasis is a surgical contraindication. Before Ca Hens (1959) introduced mediastinoscopy, there was no reliable way to understand the mediastinum before surgery. Pearson et al. and Fizhmen reported that routine resection of mediastinoscopy was performed with a resection rate of 85-95%. From August 1982 to May 1984, the author performed simultaneous CT scans on 41 cases of lung cancer diagnosed by mediastinoscopy and/or thoracotomy to understand possible mediastinal lymphadenopathy. CT was broken one layer per 1cm, lymph node> 1cm diameter was positive, according to the American Cancer Society TNM staging, and compared with surgical pathological staging. In the first stage, CT mediastinum was normal in 27 cases, 8 of which were isolated nodules.
