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.
