The use of low-dose CT scanning could prevent as many as 12,000 cases of lung cancer a year, says a new study from researchers at American Cancer Society in Atlanta. According to lead researcher Jiemin Ma, the screen method could have a major impact if used as prescribed in the National Lung Screening Trial (NLST).
The research appears this month in the journal Cancer and they say the estimate is based on projections of previous screenings on heavy smokers:
"We estimated that approximately 12,000 lung cancer deaths could potentially be averted per year through the full implementation of LDCT screening among eligible heavy smokers in the United States, based on our current knowledge of screening," the authors write. "Further studies are needed to estimate the number of avertable lung cancer deaths and the cost-effectiveness of LDCT screening under different scenarios of risk, various screening frequencies, and various screening uptake rates."
