Background: In the elderly patients, optimal surgical treatment can be difficult to achieve, because of comorbidity. Therefore, we aimed to clarify the preferred surgical management in this patient group.Methods: A retrospective study was conducted between April 2008 and March 2015 that included patients with non-small cell lung cancer (NSCLC) aged ≥ 75 years.Results: We included 44 patients who underwent partial resection (n = 20) or lobectomy (n = 24). There were no significant differences between the two groups on most variables, except for some character. Survival analysis revealed a significant difference in overall survival (OS) between the two groups; however, no significant differences existed in the disease-free survival or in the OS for stage I disease. Postoperative complications led to poor prognoses. Cox regression analysis revealed statistical significance for the Brinkman Index, the ratio of the pulmonary artery diameter to the ascending aorta diameter (PA:A), and the alveolar–arterial oxygen gradient. Only the PA:A ratio remained significant after multivariate analysis, with a higher ratio associated with better survival.Conclusion: In elderly patients with NSCLC, surgical resection should not be denied because of age alone. However, partial resection should be favored to lobectomy when possible.
