Comparative studies of the overall survival (OS) in elderly patients with nonsmall cell lung cancer (NSCLC) after surgery or stereotactic body radiotherapy (SBRT) have been limited by mixed extents of resection and different surgical approaches.792 patients aged ≥65 years with clinical stage I NSCLC underwent video-assisted thoracic surgery (VATS) lobectomy or SBRT between 2010 and 2015. The propensity score-matched primary analysis included data from the full cohort; the secondary analysis included data from a subgroup of patients with data on pulmonary function.Median OS for unmatched patients was 77 months for patients undergoing VATS lobectomy and 38 months for SBRT. The 1-, 3- and 5-year OS rates after VATS lobectomy were 92%, 76% and 65%, and after SBRT were 90%, 52% and 29% (p<0.001). Median OS for matched patients in the primary analysis was 77 months for patients undergoing VATS lobectomy and 33 months for SBRT. The 1-, 3- and 5-year OS rates after VATS lobectomy were 91%, 68% and 58%, and after SBRT were 87%, 46% and 29% (p<0.001). The survival advantage with VATS lobectomy persisted in the secondary analysis after adjusting for non-matched variables (p=0.034).We suggest that elderly patients with stage I NSCLC undergoing VATS lobectomy have a better rate of OS than patients undergoing SBRT, irrespective of matching. This could be clinically important in decision-making for elderly patients who can tolerate surgery.
