Abstract:
This article reviews regional lymph node assessment in lung cancer. In the absence of a distant metastasis, the absence or location of lung cancer spread to a regional mediastinal lymph node affects treatment options and prognosis. Regional lymph node maps have been created to standardize assessment of the N descriptor. The International Association for the Study of Lung Cancer lymph node map is used for the standardization of N descriptor assessment. CT, PET/CT with fluorodeoxyglucose, endobronchial ultrasound-guided and/or esophageal ultrasound-guided biopsy, and mediastinoscopy are common modalities used to determine the N descriptor.

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
