Dynamic nomogram for long-term survival in patients with non-small cell lung cancer after pneumonectomy

The study aims to identify prognostic factors of overall survival (OS) in patients who had pneumonectomy, in order to develop a practical dynamic nomogram model.A total of 2,255 patients with non-small cell lung cancer (NSCLC) who underwent pneumonectomy were identified from 2010-2015 in the Surveillance, Epidemiology, and End Results (SEER) database.
