Learning objectives Presenting the updates introduced by the ninth edition TNM system of lung cancers.  Establishing the relevance of the new classification for patient management. Illustrating the modifications using HRCT images and structured reports.
Read more Background Despite significant research advancements and the availability of numerous treatment options, lung malignancies continue to be the leading cause of cancer-related deaths worldwide, regardless of gender. Therefore, developing a universal nomenclature used to define the extent of lung cancer has been crucial for establishing individualized treatment plans for each patient. The TNM staging system is a globally acknowledged and periodically revised tool used to provide accurate clinical staging and enhance the prediction of therapy outcomes.The ninth edition of the TNM...
Read more Findings and procedure details The updates brought by the ninth TNM edition are as follows:T descriptorThe new edition has validated the descriptors introduced by the previous edition that pertain to the characteristics of the primary tumor, hence no additions were made with regard to the T category. N descriptorThe N2 category, which implies metastatic disease affecting the ipsilateral mediastinal and/or subcarinal nodal stations, has been split into:N2a – involvement of a single N2 station;N2b – involvement of multiple N2 stations.In the ninth TNM edition, it...
Read more Conclusion Overall, the updates brought by the 9th TNM classification of lung cancers aim to improve the accuracy of pulmonary malignant tumors staging, enabling more effective and personalized treatment strategies that can lead to better patient outcomes.  In the future, it is expected that new databases managed by the IASLC International Staging Project will continue to assist future re-evaluations of the classification, guaranteeing its value and relevance in both medical practice and research fields.
