Changes to This Summary (09/29/2017)

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.

Description of the Evidence

Added text about a third study from the U.K. Lung Cancer Screening pilot trial of a low-dose computed tomography (CT) scan that found that screening was associated with a statistically significant increase in short- and long-term smoking cessation; this effect was greatest among those whose initial screening test was positive, warranting additional clinical investigation (cited Brain et al. as reference 17).

Revised text to state that the results of these studies suggest that the net impact of a CT program on smoking cessation varied, but there appears to be a higher likelihood of smoking cessation among current smokers who have findings suspicious for lung cancer.
