Methods—We used the Surveillance, Epidemiology and End Results-Medicare registry to identify patients >65 years of age with stage I–II NSCLC and negative lymph nodes treated with SBRT vs. limited resection. We fitted a propensity score model predicting use of SBRT and compared adjusted overall survival of patients treated with SBRT vs. limited resection. Secondary analyses stratified the sample by type of limited resection (wedge vs. segmentectomy), age (≤75 vs. >75 years), and tumor size (
