The results of primary surgery for non-small cell lung cancer (NSCLC) with involved ipsilateral mediastinal or subcarinal lymph nodes (N2 disease) remains poor. However, several studies suggest that induction chemotherapy could increase long-term survival in patients with N2 disease. Therefore, accurate preoperative staging of the mediastinum remains of paramount importance for the treatment policy in patients with NSCLC. Enlarged mediastinal lymph nodes (MLN) on CT scan are positive in only half of the patients. Small lymph nodes can contain metastatic deposits of clinical importance. However, many surgeons believe that a normal mediastinum at computed tomography allows them to cancel their preoperative mediastinal exploration. It was the aim of this study to evaluate the results of cervical mediastinoscopy in patients without enlarged MLN on CT scan.
