The tumor-node-metastasis (TNM) staging system for lung cancer has been modified since its first edition in the late 1960s. Its seventh edition has been recently published and, for the first time, a truly worldwide database was analyzed in order to propose modifications in the staging. Significant changes have been made in the tumor and metastasis descriptors. Although the recommendations for the node descriptor have remained unchanged, the analysis of the factors related to this descriptor suggests that modifications will be made in the future. The forthcoming revisions of the TNM staging system might take the molecular aspects of lung cancer into consideration, aiming at a more refined staging system.
自 20 世纪 60 年代末期首次出版以来，肺癌的肿瘤-淋巴结-转移（TNM）分期系统已经过多次修订。最近发布了第七版，这是首次对真正的全球数据库进行分析，以提出分期修改建议。在肿瘤和转移描述符方面发生了重大变化。尽管淋巴结描述符的建议保持不变，但对与该描述符相关因素的分析表明，未来将进行修改。即将进行的 TNM 分期系统修订可能会考虑肺癌的分子方面，旨在建立更精细的分期系统。
