title: A radiologic review of the new TNM classification for lung cancer.
abstract: OBJECTIVE
  In 2009, a new TNM staging system was published by the International Union Against Cancer and the American Joint Committee on Cancer. The new edition will encompass non-small cell lung cancer, small cell lung cancer, and bronchopulmonary carcinoids. This article will review many important changes that have been made in the revised staging system.
  
  
  CONCLUSIONS
  It is important that radiologists learn the new system and understand the reasons for the changes to provide more accurate clinical staging.
