A risk-based model for CT screening for lung cancer was estimated to be tied to a greater number of lung cancer deaths prevented over 5 years versus a model based on current United States Preventive Service Task Force (USPSTF) guidelines, researchers said here.
Under USPSTF recommendations, validated statistical models estimated that 9 million people who ever smoked would qualify for lung cancer screening, and 46,488 lung cancer deaths were estimated as screen-avertable over 5 years. The estimated number of people needed to be screened to prevent one lung cancer death was 194 (95% CI 187-201), reported Hormuzd Katki, PhD, of the National Cancer Institute in Bethesda, Md., and colleagues.
