Decline in smoking rates could increase deaths from lung cancer

Current U.S. Preventive Services Task Force guidelines recommend annual low-dose CT screening for adults age 55 to 80 who have smoked 30 pack-years (one pack a day for 30 years), and who currently smoke or have stopped smoking within the last 15 years. This criteria is used by doctors and insurance companies to recommend and pay for scans.

According to the researchers, the percentage of lung cancer patients who smoked at least 30 pack-years declined over the study period while the proportion of cancer patients who had quit for more than 15 years rose.

The study was published in the February 24, 2015 issue of JAMA, the journal of the American Medical Association. It was funded by the Mayo Clinic and grants from the National Institutes of Health and the National Institute on Aging.
