Preliminary results from a large clinical trial sponsored by the National Institutes of Health comparing digital to film mammography found women younger than 50 with dense breasts and who are pre- or perimenopausal may benefit from having a digital mammogram.
But there appears to be no difference between the two technologies for the general population of women in the trial. Researchers are still assessing secondary findings measuring the relative cost-effectiveness of the two technologies and the effect on quality of life due to an expected reduction of false positives, the NIH said.
Launched in October 2001, the Digital Mammographic Imaging Screening Trial enrolled 49,528 women who had no signs of breast cancer at 33 sites in North America. The preliminary results were reported today in a special online publication of the New England Journal of Medicine and at a meeting of the American College of Radiology Imaging Network.
