Diagnostic Accuracy of Mediastinal Lymph Node Staging Techniques in the Preoperative Assessment of Nonsmall Cell Lung Cancer Patients

Conclusions: The majority of biopsy-proven mediastinal lymph nodes metastases are not associated with positive results on preoperative CT or PET. CT and PET have low positive predictive value for mediastinal lymph node. This study supports the routine utilization of invasive mediastinal lymph nodes staging in NSCLC, especially for patients with tumors of>4 cm diameter, regardless of CT or PET-CT results.
