Lung age formula proposed by Morris and Temple aimed to contribute toward smoking cessation programme and it was developed by Japanese Respiratory Society. It is considered as an important useful factor for predicting postopera-tive respiratory complications and survival in surgically treated patients with non small cell lung cancer. As the first for Turkish society, we aimed to evalu-ate clinical impact of lung age on postoperative complications in patients with NSCLC aged > 60 y. Survey included anatomically resected 80 NSCLC patients aged > 60 y in OMU Thoracic Surgery Clinic between years 2005 - 2015. Three groups were created using age groups <0, 0-10, >10, calculated as the difference between lung age and true age. Lung age was calculated according to Japanese Respiratory Society formula. Preoperative, intraopera-tive and postoperative prognostic factors were compared between three groups. Patient numbers in three groups were 18, 17 and 45. In preoperative factors gender, smoking, FEV1, FVC, SCC was related to lung age; postoperative respiratory complications and postoperative readmission related to respi-ratory complications were seen to have significant association with lung age. Lung age can be used as a clinical parameter to predict postoperative complication risk for NSCLC.
