Lymph nodes are small structures located in clusters throughout the body. Patients with large mediastinal nodes may undergo node sampling at mediastinoscopy or by CT-guided needle biopsy before surgery.

For the purpose of prognostication, the stations may be grouped into seven zones. Lung cancer is staged by a TNM system, based on consideration of (1) the size, location, and extent of the primary tumor (T); (2) the presence or absence of lymph node metastases (N); and (3) the presence or absence of distant metastases (M).

For example, if the patient is known to have lung cancer, then an enlarged lymph node has a 70% likelihood of tumor involvement. The lymphatic system is comprised of lymph nodes, the spleen, the thymus and bone marrow. While some evidence exists that 18F-FDG-PET may be useful in diagnosing extrapulmonary sarcoid or in following treatment response (12), further research is needed in this area to better determine its role. 2011;2011:920898. doi: 10.1155/2011/920898.
