Racial and socioeconomic disparities in lung cancer screening in the United States: A systematic review
CA: A Cancer Journal for Clinicians May 28, 2021
Sosa E, D’Souza G, Akhtar A, et al. - Researchers analyzed all available studies undertaken in the United States that have assessed the links of lung cancer screening (LCS) outcomes with race and socioeconomic status in order to find out known disparities as well as potential sources of inequity that need further inquiry to be fully mitigated, given LCS decreases nonsmall cell lung cancer mortality. Eligible studies were identified from 3 major databases. Findings demonstrated that disparities are prevalent in LCS eligibility; utilization, perception, and utility; as well as postscreening behavior and care. Presence of disparities in LCS was evident along racial and socioeconomic lines. Experts noted various steps along the LCS pipeline wherein Black and socioeconomically disadvantaged people miss the potential advantages of LCS, leading to elevated mortality. Potential sources of inequity that need further inquiry were also found. As suggested by experts, prospective trials assessing eligibility criteria for underserved populations should be implemented and interventions focused on enhancing utilization and follow-up care should be developed in order to attenuate LCS disparities.
