Risk-based lung cancer screening mitigates healthcare disparities

Embargoed Until October 26, 2023 @ 8:00 am PT Risk-based lung cancer screening using a model called the PLCOm2012-Update appears to mitigate racial and ethnic disparities and improve screening performance compared to a protocol based on the USPSTF 2021 criteria, researchers have found.Why? Because the PLCOm2012-Update model takes risk of lung cancer into account, reported a team led by Eunji Choi, PhD, of Stanford University School of Medicine. The study results were published October 26 in JAMA Oncology."The findings of this study suggest that risk-based screening reduces racial and ethnic disparities while maintaining improved screening efficiency," it noted.In 2021, the U.S. Preventive Services Task Force (USPSTF) updated its lung cancer screening recommendation, lowering the starting age from 55 to 50 and adjusting smoking history from 30 pack years to 20 pack years. The change was intended to expand the pool of eligible individuals for screening, but some expressed concern that it did not in fact accomplish this. Choi and colleagues sought to validate the updated version of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial 2012 (PLCOm2012) -- a risk prediction model based primarily on White individuals -- across races and ethnicities in the U.S., comparing it to the USPSTF's 2021 recommendation.The study included data from 105,261 adults with a history of smoking from the Multiethnic Cohort Study, which enrolled participants between 1993 and 1996 and fo...
