The IASLC Staging Project

The IASLC Staging Project is a global effort to study and improve the current staging system for lung cancer, mesothelioma, thymic and esophageal cancer. 

Over the past two decades, the project has produced a steady stream of evidence-based recommendations for the TNM Classification for Thoracic Cancers, published by the Union for International Cancer Control (UICC) and the American Joint Committee on Cancer (AJCC).

We are seeking volunteers to submit data on thoracic cancer patients diagnosed between January 1, 2011, and December 31, 2019 to a secure, electronic data capture system (provided by Cancer Research And Biostatistics (CRAB) in Seattle, Washington).

Summary of the 8th Edition

All data with a diagnosis date between January 1, 2011, and December 31, 2019 are eligible. The deadline to submit cases for inclusion is December 31, 2021. 

For more information, contact staging@iaslc.org.

What You Will Need for Data Submission

8th Edition of the TNM Classification of Malignant Tumors

The IASLC Staging and Prognostic Factors Committee (SPFC) proposed revisions to the lung cancer staging system for the 8th edition of the TNM Classification of Malignant Tumours. The UICC and the AJCC accepted these revisions, and the 8th edition of the TNM Classification was implemented in January 2017.

In the United States, implementation was delayed until January 2018; now, the new edition has been enacted worldwide. The objective was to further explore and analyze the impact on prognosis of tumor size and of the different T descriptors; the prognostic significance of tumor burden in hilar and mediastinal lymph nodes; and the confirmation of the revised M1 categories (M1a and M1b) of the seventh edition of the classification along with the prognostic impact of number and anatomic location of metastases.
