Mediastinal Staging in Non-Small Cell Lung Cancer

In the absence of distant metastases, lung cancer treatment is determined by the results of mediastinal lymph node staging. Occult mediastinal lymph node metastases can be missed by radiologic and needle-based staging methods. Aggressive staging of mediastinal lymph nodes improves staging accuracy. Improved accuracy of mediastinal lymph node staging results in more appropriate lung cancer treatment. Improved accuracy of mediastinal lymph node staging can improve stage-specific survival from lung cancer.
