A frican American patients are more likely to develop and die of lung cancer than White patients (1). The U.S. Preventive Services Task Force (USPSTF) recommends lung cancer screening (LCS) with low-dose chest CT to reduce lung cancer mortality. However, initial screening guidelines were derived from studies in which only 4% of study participants were African American smokers. Study investigators from the Southern Communities Cohort study, a prospective cohort study including 48 364 adult smokers in the southeastern United States, found that existing USPSTF guidelines may exclude a large percentage of high-risk African American smokers (2). Partly to address equity concerns, the USPSTF recently issued revised recommendations lowering the threshold for LCS eligibility from age 55 to age 50 and from at least 30 pack-years to at least 20 pack-years (3). However, rates of lung cancer for a given pack-year history are much higher in African American patients (4).Newly revised recommendations defining eligibility exclusively based on pack-year thresholds ignore racial and ethnic differences in lung cancer risk. Previous studies have suggested that USPSTF guidelines exclude high-risk racial and ethnic minority groups. However, few studies use recent data to evaluate the potential impact of revised USPSTF guidelines on racial and ethnic disparities in LCS eligibility. Our purpose was to evaluate the impact of revised USPSTF guidelines on racial and ethnic disparities in LCS eligibility using survey data from the 2019 Behavioral Risk Factor Surveillance System (BRFSS).
Materials and MethodsOur study used publicly available de-identified data and was therefore exempt from institutional review board review. No data usage agreements were required. Study results were reported using Strengthening the Reporting of Observational Studies in Epidemiology guidelines (5).Background: To address disparities in lung cancer screening (LCS) that may exclude large numbers of high-risk African American smokers, revised U.S. Preventive Services Task Force (USPSTF) recommendations lowered LCS eligibility thresholds. However, there are limited recent data about the impact of newly revised guidelines on disparities in LCS eligibility.Purpose: To evaluate the impact of revised USPSTF guidelines on racial and ethnic disparities in LCS eligibility.
Materials and Methods:Cross-sectional survey data from 20 states were retrospectively evaluated from the 2019 Behavioral Risk Factor Surveillance System survey (median response rate, 49.4%). Respondents without a history of lung cancer aged 55-79 years (ie, under the previous guidelines) or aged 50-79 years (ie, under the revised guidelines) were included. Multivariable logistic regression analyses were performed to evaluate the association between race and ethnicity and LCS eligibility. All analyses were performed accounting for complex survey design features (ie, weighting, stratification, and clustering). Results: Under previous guidelines, 11% of 67 567 weighted survey respondents were eligible for...
