Overview
Over the past two decades, the IASLC Staging Project has produced a steady stream of evidence-based recommendations for the TNM Classification for Thoracic Cancers, published by "Union for International Cancer Control (UICC) and the American Joint Council on Cancer (AJCC)". The project is now entering the third cycle, with the goal of developing recommendations for the 9th edition of TNM. Staging lung cancer and other thoracic malignancies accurately is critical in deciding treatment regimens and ensures best standardized care for patients worldwide. New data elements such as genetic biomarkers, protein alterations and copy number alterations will be added to the staging project for the first time, and such additions and enhancements to the system may significantly improve the current staging system, leading to more precise treatment decisions and improvement in patient survival.
Chair of Committee

Thank you for submitting to the 9th Edition
The IASLC is grateful to its members and other thoracic oncology professionals who submitted patient data to better inform the 9th Edition of the TNM Classification for Thoracic Cancers. As the data collection window for the 9th Edition is now closed, the IASLC encourages early applications to the 10th Edition of TNM Classification for Thoracic Cancers. Check back often as more information will become available.

IASLC International Staging Project Data Query Application (8th Edition)
Access to the combined dataset is restricted, however, an investigator may propose a research question for analysis. Such analyses are done collaboratively by CRAB, the IASLC SPFC, and the requestor. An investigator with a research question will complete an initial form outlining the question and the proposed data requirements.
To submit a project proposal please complete the form linked here.
Based on the proposal, feasibility will be determined and a cost will be determined for the analysis effort. Once it is determined to be feasible, the research question will be submitted for approval to the SPFC and the IASLC.
