Science Newsline Medicine & Health Care, May 23, 2013 — Physicians have more information to share with their patients about the benefits and risks of low-dose computed tomography (LDCT) lung cancer screening following today’s publication in the New England Journal of Medicine of the results of the first (of three planned) annual screening examinations from the National Lung Cancer Screening Trial (NLST).
“For a cancer screening to work, it’s important to verify that it can in fact discover cancers early. The analysis of NLST participants’ initial annual screening examination provides evidence that the number of early-stage cancers detected in the trial’s CT arm were significantly greater than the number detected in the chest X-ray arm,” says Timothy Church, Ph.D., a biostatistician and professor in the School of Public Health at the University of Minnesota who has been involved with the NLST’s design, implementation and analysis.
