    Lung cancer screening needs smoking cessation programme
    • Manfred Neuberger, professor of environmental health and medicine Medical University of Vienna, Center of Public Health

    A quit rate of 21% in controls and 24% in screened persons show that CT screening is a poor motivation to quit. The authors emphasize that the quit rate was 30% in patients with a positive result on CT who needed additional clinical investigation, however, the quit rate was only 15% in persons receiving a negative CT result. This shows that CT screening lowers the motivation to quit if a negative result (expected for the majority) nourishes misperceptions. Zeliadt et al. ( JAMA Intern Med 2015; 175:1530-7) found that in 49% these beliefs were reinforced and potentially exacerbated by screening and lowered the motivation to participate in smoking cessation programs. Therefore CT screening for lung cancer without accompanying smoking cessation program could be harmful.
