Sineshaw HM, et al. - Researchers investigated county-level differences in receipt of curative-intent surgery for early-stage non-small cell lung cancer (NSCLC) as well as factors adding to such differences in the United States. This study included patients (n = 179,189, aged ≥ 35 years) who received a diagnosis of stage I to II NSCLC between 2007 and 2014 in 2,263 counties, selected from 39 states, the District of Columbia, and Detroit population-based cancer registries; the data were collected by the North American Association of Central Cancer Registries. The range of surgery receipt for early-stage NSCLC according to county was from 12.8% to 48.6% in the lowest decile of counties, to 74.3% to 91.7% in the highest decile of counties, during 2007 to 2014. Across counties in the United States, a substantial variation was reported in the receipt of curative-intent surgery for early-stage NSCLC, with pockets of low receipt counties in each state. Unfavorable area-level socioeconomic and health-care delivery factors defined low surgery receipt counties.
