Purpose: Racial disparities in survival persist in patients with early-stage non-small cell lung cancer (NSCLC). Possible contributors to these disparities are stage at diagnosis, comorbidities, and socioeconomic factors. The goal of this study is to compare differences in survival between black and white patients from veteran and non-veteran populations, while accounting for treatment. Methods: Black and white men aged ≥65 years diagnosed with stage I NSCLC from 2001-2009 were identified in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database and Veterans Affairs (VA) cancer registry. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for differences between black and white patients in postoperative mortality among surgery patients, 5-year overall survival (OS), and lung cancer specific survival (LCSS). Results: There were 8,744 and 7,895 patients in the SEER and VA cohorts, respectively. Overall, black patients were less likely to be treated than white patients (74% vs 85% in SEER, p
