The third phase of the IASLC Staging Project for thoracic malignancies has concluded. We are proud to announce that the Staging and Prognostic Factors Group’s recommended revisions have been adopted by the American Joint Committee on Cancer (AJCC) for their version 9 staging protocols for lung cancer, thymic tumors, and pleural mesothelioma.
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.
The revised TNM classification system for Lung Cancer, Thymic Epithelial Tumors, Mesothelioma, and Esophageal Cancer are described in the 9th Edition IASLC Staging Cards and the Staging Manual for Thoracic Oncology, 3rd Edition.

The IASLC Staging Project: 9th Edition TNM on Lung Cancer Considered
In this episode of Lung Cancer Considered, host Dr. Stephen Liu and guests preview the publication of the IASLC Ninth Edition of Tumor, Node, and Metastasis (TNM) Classification System for Lung Cancer. The new edition will be published in January 2025 and has some important changes that reflect an evolving understanding of the disease and a more rigorous analysis of data from around the world.
Staging Project for the Version 10 TNM Staging System
The fourth cycle of the IASLC Staging Project for version 10 of the TNM classification system is now underway! The main goals for version 10 are to further refine the anatomical TNM staging system and to consider how other prognostic factors, such as molecular biomarkers and delineation of screen-detected lung cancer, impact patient prognosis.
To address these objectives, we are building a new Staging Database of lung cancer, thymic tumors and mesothelioma cases, which will prioritize data quality and completeness and global representativeness. Institutions will be selected based on these criteria to determine their eligibility to contribute clinical cases to the database.
