The eighth edition of the tumor-node-metastasis (TNM) classification classified stage III non-small cell lung cancer in sub-stages IIIA, IIIB, and IIIC. There is no further subclassification but Stage IIIA represents already a heterogeneous group of lung cancers invading chest wall/mediastinal organs or with concomitant N2 disease. This heterogeneity poses a tremendous challenge for surgeons, oncologists, radiation-oncologist involved in the management of patients with Stage IIIA disease. This series is a comprehensive overview about management of stage IIIA lung cancer by leading experts internationally recognized.
