Medical oncologists are faced with multiple factors to consider when staging a patient with suspected or confirmed non-small cell lung cancer (NSCLC).

We hope that the adherence to these guidelines will standardize and improve preoperative and intraoperative LN staging and pathologic evaluation of non-small cell lung cancer.

Objective: We evaluated the surgical results and TNM classification of the non-small-cell lung cancer with intrapulmonary metastasis in the same lobe as the primary.
