Objective: The early and local advanced stages (IA-IIIA) of non-small cell lung cancer (NSCLC) warrant the curative treatment approach of surgery. However, despite the surgical approach, survival depends on a number of factors. The aim of the study was to examine the factors that affect survival in operated NSCLC patients with these stages. Methods: A cohort of 231 operated patients with IA, IB, IIA, IIB, and IIIA stages of NSCLC were analyzed. The effects of age, sex, comorbidity, performance status, histopathology of the tumor, T stage, N stage, pleural invasion, surgical resection type and postoperative resection margin invasion on the survival of the patients were examined with Kaplan-Meier and Cox Regression analyses. Results: Advanced age (OR=1.042 for every passing year, CI=1.020-1.064), adenocarcinoma histopathology (OR=1.676 CI=1.178-2.384), N2 invasion (OR=2.389 CI=1.46-4.239), pleural invasion (OR=2.403 CI=1.569-3.678), resection margin invasion (OR=2.401, CI=1.141-5.048) and pneumonectomy as the type of surgical operation (OR=2.313, CI=1.467-3.647) were found to be independent prognostic factors of mortality. Conclusion: Follow-up of the NSCLC cases with advanced age, an adenocarcinoma type, visceral pleural invasion, N2-lymph node invasion, a history of pneumonectomy, and a resection margin invasion should be undertaken more atten­tively during planning of surgical operation and postoperative period.
