Reduced Lung-Cancer Mortality with Volume CT Screening in a Randomized Trial
Individuals at high risk for lung cancer were randomized to low dose CT screening (years 0, 1, 3, and 5.5) or observation. At 10 years the cumulative rate ratio for lung cancer death was 0.76 in the screened population of men (p=0.01) and 0.67 in the screened population of women, demonstrating a strong benefit for screening.
