Mediastinal lymph node staging: from noninvasive to surgical.

OBJECTIVE
The purpose of this review is to describe the current lymph node stations and lymph node staging of non-small cell lung carcinoma. Minimally invasive and invasive methods of mediastinal lymph node staging are emphasized, and the relative accuracy and limitations of each modality are described.
