To review the IASLC lymph node map used in the 7th edition of the TNM classification of lung cancer  To highlight the differences between the IASLC and ATS lymph node maps To discuss the size criteria and pitfalls for each lymph node station   To review the drainage pattern of thoracic lymph nodes

The anatomic definitions of the lymph node stations in the IASLC lymph node map and its differences from the ATS map will be reviewed and illustrated using the following formats: Tables Medical illustrations Color coded CT images Thoracic lymph node drainage patterns Mediastinal lymph nodes Pulmonary lymph nodes Chest wall lymph nodes Discussion of size criteria and pitfalls for each lymph node station Self-assessment quiz

Viewers of this exhibit will learn to: Accurately define and identify thoracic lymph nodes as they are characterized in the new IASLC lymph node map used in the seventh edition of the TNM classification for lung cancer, and recognize its distinction from the ATS lymph node map Recognize size criteria and pitfalls associated with each lymph node station Understand thoracic lymph node drainage pattern as they pertain to lung cancer
