Answer

Thoracic metastatic adenopathy is an important prognostic factor in lung cancer. Detecting nodal involvement is viable for surgical planning since tumors with contralateral mediastinal and hilar nodes are considered nonresectable. Although regional lymph node (N) classifications have not changed, a unified map of lymph node stations was adopted by the IASLC. The new map reconciles discrepancies among previous nodal mapping proposals and introduces the concept of lymph node zones. [19, 25]
