Predictors associated with Clavien–Dindo complications in lung cancer surgery: A retrospective cohort study

Older age (≥70 years) is associated with higher rates of postoperative complications (CD classification ≥ II) but is not an independent predictor when adjusting for other factors. Comorbidities such as COPD and surgical factors, including pneumonectomy and conversion to thoracotomy, are significant contributors. These findings emphasize the need for comprehensive, multifactorial risk assessments to guide perioperative management and improve outcomes in elderly lung cancer patients.
