This long-awaited lung cancer staging update serves as the model for the AJCC 8 update that will be published in the near future. The primary changes involve T status and an expansion of M status to include a single distant metastasis as T4c. Stage IA is now subdivided into 3 stages, IIIC has been added, and stage IV has been expanded into IVA and IVB. Overall, the previous 7 TNM stages have been expanded to 11.
