title: Lung Carcinoma Staging Problems.
abstract: The tumor-node-metastasis (TNM) system is the most commonly used staging system for cancers, including lung cancer. The TNM descriptors and the stage groupings reflect differences in patient prognosis and choices for specific therapies. Generally, the higher the T, N, or M, and the higher the stage grouping, the worse the prognosis is for patients in that category. TNM stage is traditionally the most important factor predicting survival of lung cancer patients.
