手术切除是治疗肺癌的最理想方法,而手术能否切除在很大程度上取决于有无纵隔淋巴结转移。尽管 CT 发现肺门及纵隔淋巴结的敏感性各家报告不一,且以淋巴结的大小作为诊断恶性肿瘤的标准有一定局限性,但目前绝大多数研究者认为,CT 为发现纵隔及肺门淋巴结 Surgical resection is the most ideal method for treating lung cancer, and the ability to remove the disease depends largely on the presence or absence of mediastinal lymph node metastases. Although the sensitivity of CT findings in hilar and mediastinal lymph nodes varies, and the size of lymph nodes as a standard for diagnosing malignant tumors has certain limitations, the vast majority of researchers believe that CT is the discovery of mediastinal and hilar lymph nodes.
