OBJECTIVES: Smoking is a modifiable risk factor for lung resections but to what extent preoperative smoking cessation reduces that risk remains unclear. The study hypothesis was that the potential benefit of smoking cessation can be assessed by measuring the risk difference between active and former smokers in a large cohort of patients.
METHODS: Data were extracted from the French Society of Thoracic and Cardiovascular Surgeons (Société Française de Chirurgie Thoracique et Cardiovasculaire) database. The study cohort comprised patients who underwent lung resection for cancer from January 2002 to December 2020 and for which information on smoking status was available. The risk of overall and specific postoperative complications according to smoking status was defined by logistic regression models, and results were presented in terms of odds ratios (ORs) and relative 95% confidence intervals (CIs) adjusted for confounding factors.
RESULTS: Of the 7204 analysed patients at the time of their operations, 20.2% were active smokers, 60.7% were ex-smokers and 19.1% were never smokers. Compared to former smokers, active smokers experienced a higher rate of respiratory complications (OR 1.5, CI 1.2-1.7) and infections (OR 1.6, CI 1.3-1.9). Postoperative atelectasis was significantly reduced in former smokers (3%) compared to active smokers (6.9%, P < 0.01). In active smokers, the risk was related to the level of exposure, being higher for smokers of more than 40 pack-year.
CONCLUSIONS: After lung surgery, active smokers experience a higher risk of respiratory complications, infections and prolonged air leak compared to former smokers. This risk seems to be related to the level of exposure.
