Persistent race- and sex-based disparities in lung cancer screening eligibility

Objective: To evaluate race- and sex-based disparities in lung cancer screening eligibility under the 2013 US Preventive Services Task Force, 2021 US Preventive Services Task Force, and National Comprehensive Cancer Network lung cancer screening guidelines. Methods: Participants in the Southern Community Cohort Study with a smoking history diagnosed with lung cancer from 2002 to 2021 were identi fi ed for analysis. Differences in age at lung cancer diagnosis and smoking characteristics were evaluated among 4 groups: Black men, Black women, White men, and White women. Results: A total of 2011 patients with lung cancer met study inclusion criteria, of whom 968 (48.1 % ) were women and 1248 (62.1 % ) were Black. Under the 2013 guideline, Black men with lung cancer were signi fi cantly less likely to be eligible for screening when compared with White men with lung cancer (37.7 % vs 62.4 % ; P < .001), and Black women with lung cancer were signi fi cantly less likely to be eligible for screening when compared with White women with lung cancer (27.8 % vs 56.7 % ; P < .001). Under the 2021 guideline, 62.6 % of Black and 73.8 % of White men ( P < .001) with lung cancer would have been eligible for screening, resulting in an 11.2 percentage point difference in screening eligibility between Black and White men. Under the 2021 guideline, 50.3 % of Black and 74.9 % of White ( P < .001) women with lung cancer would have been eligible for screening; notably, there remained a 24.6 percentage point difference in screening eligibility between Black and White women. In multivariable-adjusted analysis, under the 2021 USPSTF guideline, Black men with lung cancer had 46 % lower odds of being eligible for screening compared with White men with lung cancer (multivariable-adjusted odds ratio [aOR], 0.54; 95 % CI, 0.39-0.76; P < .001) and Black women with lung cancer had 66 % lower odds of being eligible for screening compared with White women with lung cancer (aOR, 0.34; 95 % CI, 0.25-0.46; P < .001). The National Comprehensive Cancer Network guideline increased the proportion of patients with lung cancer eligible for screening in each group. Conclusions: In this analysis of patients with lung cancer in the Southern Community Cohort Study, there remained a large gap in lung cancer screening eligibility between Black and White men and women under the 2021 US Preventive Services Task Force guideline. Only 50 % of Black women and 63 % of Black men diagnosed with lung cancer would have quali fi ed for screening. (J Thorac Cardiovasc Surg 2024;168:248-60)
