CISNET Provides Support for Development of Lung Cancer Screening Recommendations
The CISNET Lung Working group was commissioned by the U.S. Preventive Services Task Force (USPSTF) in 2011-2013 and 2019-2021 to conduct decision analyses to inform their lung cancer screening recommendations. In the first analysis done for the 2013 recommendations, five lung natural history models concluded that implementing annual low-dose CT (LDCT) screening for lung cancer would result in lung cancer mortality reductions in the US, and that screening individuals aged 55 through 80 years with 30 or more pack-years’ exposure to smoking and no more than 15 years of quitting had a favorable benefit–harm ratio for (de Koning et al, 2014). This work supported the Task Force's 2013 lung cancer screening recommendation (Moyer USPSTF, 2014).
In the 2019-2021 decision analysis to inform the 2021 USPSTF lung screening recommendations, four lung natural history models were used to extrapolate the benefits and harms of lung LDCT screening strategies with either pack-year and year-since-quit eligibility criteria as the 2013 recommendations (risk factor–based) or with eligibility based on individual risk calculated using a multivariate risk prediction model (risk model–based). The findings suggest that optimally targeted LDCT screening could lead to important reductions in lung cancer mortality and result in significant life-years gained (Meza et al, 2021; Meza et al, AHRQ). The study found that screening individuals aged 50-80 who have a history of smoking a pack of cigarettes every day on average for at least 20 years would result in more benefits than the 2013 criteria and less disparities in screening eligibility by gender and race/ethnicity. The study also found that risk model–based vs risk factor–based strategies were estimated to be associated with more benefits and fewer radiation-related deaths but more overdiagnosed cases. This work supported the Task Force's 2021 lung cancer screening recommendations, which expanded screening to age 50-80 and to include those with 20 pack-years of smoking exposure or more (USPSTF, 2021)
Results of these studies were published in the following articles in the Annals of Internal Medicine in 2013 and in JAMA in 2021:
