BACKGROUND The true incidence of occult N2 lymph node metastasis in patients with clinical N0 non-small cell lung cancer (NSCLC) remains controversial. Estimation of the probability of N2 lymph node metastasis can assist physicians when making diagnosis and treatment decisions. METHODS We reviewed the medical records of 605 patients (group A) and 211 patients (group B) with computed tomography-defined N0 NSCLC that had an exact tumor-node-metastasis stage after surgery. Logistic regression… CONTINUE READING
