Task: Answer Verification
Input (English): Question: Is smoking a perioperative risk factor and prognostic factor for lung cancer surgery?
Answer: Smokers with lung cancer tended to have advanced lung cancer, impaired pulmonary function, and high morbidity after lung cancer surgery. Although multivariate analysis did not show that smoking was associated with poor outcome, non-smokers had significantly better overall survival, even for patients with stage IA lung cancers.
