Mediastinal lymph node sampling is critical to the initial diagnosis and staging of lung and esophageal cancers and lymphoma. Additionally, it is essential for detecting primary or recurrent nodal metastases in extrathoracic malignancies.
Mediastinal lymphadenopathy is when the lymph nodes in the chest become enlarged. A number of conditions can cause this, including infections, inflammatory diseases, autoimmune conditions, and certain cancers. Mediastinal lymphadenopathy doesn't usually cause symptoms.

regional lymph node involvement. T. primary tumor. Lung cancer is the leading cause of cancer mortality in both men and women in the United States. 1 Staging plays a critical role in guiding treatment selection and determining prognosis of cancer.
Accurate clinical or pretreatment stage classification of lung cancer leads to optimal treatment outcomes and improved prognostication. Such classification requires an accurate assessment of the clinical extent of regional lymph node metastasis.
