Comments on the eighth edition of the TNM classification for lung cancer. Radical changes and limitations: Does size matter?

ConclusionsThe new staging of lung cancer is based on analysis of survival in large databases, based on tumor size and disease proliferation, and is therefore expected to assess the prognosis of the individual patient more accurately. Based on the current edition of the TNM staging system many patients will be given a different staging category,. It is evident that improved survival may reflect the expected improvements in diagnosis and treatment, the net effect being a stage-for-stage survival increase at all stages. This 8th edition of the TNM classification for lung cancer has placed additional emphasis on tumor size.
