Although tobacco smoking is one of the major causes of lung cancer the correlation between smoking status and the survival of patients is uncertain. Materials and Method: Medical records of 249 patients who underwent pulmonary resection for NSCLC were retrospectively reviewed. Patients were divided into smokers and never-smokers. Annual frequency, demographic and clinical characteristics and overall survival were compared between the groups. Results: The annual frequency of never-smokers between the years 2002 and 2012 was 33.2, 24, 37.5, 25, 34.3, 35.4, 29.4, 22.7, 22.2, 35.7 and 28.5%, respectively. There were no statistically significant difference in terms of the distribution of age (p=0.993), FEV1 measurement (p=0.476), type of resection performed (p=0.564) and tumor histology (p=0.920) between the groups. The median survival time was similar in both groups (72 vs 76 months, smokers vs. never-smokers. Log-rank test; P=0.654). Conclusion: The proportion of never-smokers were approximately 30% in our cohort. In long follow-up, smoking status was not an independent risk factor for a poorer prognosis in patients operated for NSCLC.}, number={4}, publisher={Selçuk Üniversitesi}, organization={Yok}
