Impact of Smoking Cessation Duration on Postoperative Complications in Lung Cancer Surgery

This study aims to investigate the relationship between the duration of smoking cessation before surgery and postoperative complications in lung cancer patients undergoing surgery. Lung cancer surgery patients who have recently quit smoking or are long-term nonsmokers will be evaluated to determine if the timing of smoking cessation impacts the risk of complications after surgery. By analyzing these factors, the study seeks to provide guidance on optimal smoking cessation timing to reduce postoperative risks.
