Preoperative Risk Factors for Pathologic N2 Metastasis in Positron Emission Tomography-Computed Tomography–Diagnosed N0–1 Non-Small Cell Lung Cancer

摘要

BackgroundAccurate mediastinal lymph node staging is vital for the optimal therapy and prognostication of patients with lung cancer. This study aimed to determine the preoperative risk factors for pN2 disease, as well as its incidence and long-term outcomes, in patients with clinical N0–1 non-small cell lung cancer.
