MedicalResearch.com Interview with:
Harry J de Koning, MD PhD
Professor of Public Health & Screening Evaluation
Rotterdam, The Netherlands.
MedicalResearch.com: What are the main findings of the study?
Dr. de Koning: Annual CT screening for lung cancer has a favorable benefit-to-harm ratio for individuals ages 55 through 80 years with 30 or more pack-years’ exposure to smoking. It would lead to 50% (model ranges, 45% to 54) of cases of cancer being detected at an early stage (stage I/II), 575 screenings examinations per lung cancer death averted, a 14% (range, 8.2% to 23.5%) reduction in lung cancer mortality, 497 lung cancer deaths averted, and 5250 life-years gained per the 100 000-member (1950-) cohort. Harms would include 67 550 false-positive test results, 910 biopsies or surgeries for benign lesions, and 190 overdiagnosed cases of cancer (3.7% of all cases of
lung cancer [model ranges, 1.4% to 8.3%]), again for a 100 000-member (1950-) cohort.
