Imaging plays a key role in clinical staging of lung cancer and guiding therapy. A thorough understanding of the staging system including the nomenclature and updates is necessary to tailor treatment plans and optimize patient care. The 9th edition of the Tumor, Node, Metastasis staging system for lung cancer has no changes for T classification and subdivides N2 and M1c categories. In nodal staging, N2 splits into N2a, ipsilateral mediastinal single station involvement and N2b, ipsilateral mediastinal multiple stations involvement. In the staging of multiple extrathoracic metastases, M1c splits into M1c1, multiple extrathoracic metastases in one organ system and M1c2, multiple extrathoracic metastases in multiple organ systems. Awareness of the proposed changes in TNM-9 staging classification is essential to provide methodical and accurate imaging interpretation.
影像学在肺癌的临床分期及指导治疗中发挥着关键作用。全面了解包括命名法及更新内容在内的分期系统，对于制定治疗方案和优化患者护理至关重要。肺癌的第9版肿瘤、淋巴结、转移（TNM）分期系统在T分类方面没有变化，对N2和M1c类别进行了细分。在淋巴结分期中，N2分为N2a（同侧纵隔单站受累）和N2b（同侧纵隔多站受累）。在多发胸外转移的分期中，M1c分为M1c1（一个器官系统内的多发胸外转移）和M1c2（多个器官系统内的多发胸外转移）。了解TNM-9分期分类中的拟议变化对于提供系统且准确的影像学解读至关重要。
