IntroductionDisparities in treatment exist for nonwhite and Hispanic patients with non-small cell lung cancer, but little is known about disparities in the use of staging tests or their underlying causes.MethodsProspective, observational cohort study of 3638 patients with newly diagnosed non-small cell lung cancer from 4 large, geographically defined regions, 5 integrated health care systems, and 13 VA health care facilities.ResultsMedian age was 69 years, 62% were men, 26% were Hispanic or nonwhite, 68% graduated high school, 50% had private insurance, and 41% received care in the VA or another integrated health care system. After adjustment, positron emission tomography (PET) use was 13% lower among nonwhites and Hispanics than non-Hispanic whites (risk ratio [RR] 0.87, 95% confidence interval [CI] 0.77–0.97), 13% lower among those with Medicare than those with private insurance (RR 0.87, 95% CI 0.76–0.99), and 24% lower among those with an elementary school education than those with a graduate degree (RR 0.76, 95% CI 0.57–0.98). Disparate use of PET was not observed among patients who received care in an integrated health care setting, but the association between race/ethnicity and PET use was similar in magnitude across all other subgroups. Further analysis showed that income, education, insurance, and health care setting do not explain the association between race/ethnicity and PET use.ConclusionsHispanics and nonwhites with non-small cell lung cancer are less likely to receive PET imaging. This finding is consistent across subgroups and not explained by differences in income, education, or insurance coverage.
