Incidental N2 Nodal Disease and the Heterogeneity of Stage IIIA N2 NSCLC
Article
Probably the most contentious areas of lung cancer management is stage IIIA NSCLC, with N2 nodal involvement, the nodes outside of the lungs, toward the middle of the chest but on the same side as the main tumor. One of the key issues is that the staging is the same whether there's a single microscopically involved lymph node or multiple enlarged lymph nodes in a few areas of the mediastinum (mid-chest, between the lungs). But the outcomes of these groups of patients is very different, so it may be worth thinking about them a little differently.
