The third phase of the IASLC Staging Project for the 9th Edition of the Tumor, Node, Metastasis (TNM) classification system is coming to a close. We are proud to present the innovations proposed for the 9th Edition TNM system, which were made possible by rigorous analysis of data generously submitted by investigators from across the world.
Thank you to all investigators and their institutions who submitted data and to the Staging and Prognostic Factors Group members for their voluntary contributions to this project.

10th Edition TNM Classification System
The IASLC is actively planning for the fourth cycle of the Staging Project for the 10th Edition of the TNM classification system, which officially launches at the end of 2024. This new cycle of the project will include many changes, including a selection process for investigators wishing to submit data in order to ensure high data quality and fair global representation of the staging database. Furthermore, the main objective of the 10th edition revisions will be to consider how other prognostic factors, such as molecular biomarkers and delineation of screen-detected lung cancer, impact patient prognosis.
More information about the process for submitting data to the 10th Edition database will be available in the fall of 2024.
