Pdf Summary

This study evaluates lung cancer screening (LCS) eligibility criteria to better capture high-risk individuals in a predominantly minority population. Current U.S. Preventive Services Task Force (USPSTF) criteria require a 20 pack-year smoking history and exclude many at-risk patients, particularly among underrepresented racial and ethnic groups.<br /><br />Using data from 1,479 lung cancer patients with a history of tobacco use treated at University of Illinois Hospital (2010-2024), the study compares three LCS eligibility criteria: USPSTF, Potter, and American Cancer Society (ACS). The Potter criteria replace the 20 pack-year threshold with a 20-year smoking duration threshold, while the ACS criteria remove the requirement that smoking cessation must be within the past 15 years.<br /><br />Results show that USPSTF criteria identified only 64.8% of these patients as eligible for screening. The Potter criteria increased capture to 77%, while the ACS criteria identified 69.5%. Notably, the additional 12.2% of patients captured only by Potter criteria were significantly more likely to be Black (77%) or Hispanic, highlighting that Potter criteria better address racial disparities. Conversely, patients added only by ACS criteria were less likely to be Black. About 18.3% of patients met none of the criteria.<br /><br />The findings suggest that the Potter criteria reduce unintentional racial bias inherent in current USPSTF criteria by incorporating smoking duration rather than pack-years alone. Expanding LCS eligibility to include Potter criteria could improve early lung cancer detection in diverse populations, particularly among underrepresented minorities historically excluded by pack-year-based thresholds.<br /><br />In conclusion, incorporating the Potter criteria alongside USPSTF guidelines may enhance equitable lung cancer screening access and outcomes in racially diverse groups, addressing existing disparities in lung cancer detection and care.<br /><br />References include major lung screening studies and recent analyses demonstrating race and ethnicity disparities in LCS eligibility.
