Abstract

Lung cancer is the most common and deadly cancer worldwide. The 9th edition of the tumor node meta (TNM) classification system, effective from January 1, 2025, introduces significant updates. Notably, the N2 category is newly divided into N2a (single-station involvement) and N2b (multiple-station involvement), which reflects distinct prognostic implications. Additionally, the M1c category is now subcategorized into M1c1 (multiple metastases in a single organ system) and M1c2 (metastases in multiple organ systems), affecting stage classification. This reclassification allows for potential downstaging, which could expand treatment options for affected patients. Accurate imaging remains crucial for the classification of anatomical stages. As the TNM system evolves, enhanced imaging precision will play a key role in implementing these updates and ultimately improve patient outcomes. KEY POINTS: Question The 9th TNM for lung cancer introduces changes in the N2 and M1c descriptors, to better align with new therapeutic options and outcome studies. Findings Proper knowledge of the key changes of the 9th TNM can help radiologists offer clinicians a meaningful report. Clinical relevance Radiologists should incorporate the 9th TNM classification into their reports and discussions in multidisciplinary meetings, thus ensuring a common language across disciplines to enable clearer communication with other specialists, supporting more precise and cohesive decision-making in patient care.

第九届肺癌TNM的实施:放射科医师的实践见解。
肺癌是世界上最常见、最致命的癌症。从2025年1月1日起生效的第9版肿瘤淋巴结元(TNM)分类系统进行了重大更新。值得注意的是,N2类别被新划分为N2a(单站受累)和N2b(多站受累),这反映了不同的预后意义。此外,M1c类别现在被细分为M1c1(单器官系统多发转移)和M1c2(多器官系统转移),影响分期分类。这种重新分类允许潜在的降低分期,这可以扩大受影响患者的治疗选择。准确的成像仍然是解剖分期分类的关键。随着TNM系统的发展,增强的成像精度将在实施这些更新并最终改善患者预后方面发挥关键作用。第9次肺癌TNM引入了N2和M1c描述符的变化,以更好地与新的治疗方案和结果研究相一致。正确了解第9期TNM的关键变化可以帮助放射科医生为临床医生提供有意义的报告。临床相关性放射科医生应将第9种TNM分类纳入他们的报告和多学科会议的讨论中,从而确保跨学科的通用语言,以便与其他专家进行更清晰的沟通,支持更精确和有凝聚力的患者护理决策。

期刊介绍: European Radiology (ER) continuously updates scientific knowledge in radiology by publication of strong original articles and state-of-the-art reviews written by leading radiologists. A well balanced combination of review articles, original papers, short communications from European radiological congresses and information on society matters makes ER an indispensable source for current information in this field. This is the Journal of the European Society of Radiology, and the official journal of a number of societies. From 2004-2008 supplements to European Radiology were published under its companion, European Radiology Supplements, ISSN 1613-3749.
