The IASLC/ITMIG Thymic Malignancies Staging Project Development of a Stage Classification for Thymic Malignancies
The lack of an official-stage classification system for thymic malignancies is an issue that hampers progress in this rare disease. A collaborative effort by the International Association for the Study of Lung Cancer and the International Thymic Malignancies Interest Group is underway to develop proposals for such a system. A database of more than 10,000 cases worldwide has been assembled to provide a solid basis for analysis. This report outlines the structure of the effort and the process that has been designed.
