Computer-aided detection does not improve mammogram accuracy
Date:7/27/2011

Using computer-aided detection (CAD) software to help analyze and interpret mammograms does not improve accuracy, according to a study published online July 27 in the Journal of the National Cancer Institute.

CAD software, used currently for analyzing three out of four mammograms in the United States, identifies patterns associated with breast cancers and marks potential abnormalities for the radiologist to consider before making a final recommendation.

To learn whether CAD leads to more accurate reading of mammograms, Joshua J. Fenton, M.D., at the University of California, Davis, and colleagues analyzed data from more than 1.6 million film screening mammograms carried out at facilities in seven states from 1998 to 2006. The facilities participate in the Breast Cancer Surveillance Consortium, a federally supported network in which data quality is rigorously monitored.

Of 90 total facilities, 25 adopted CAD and used it for an average of 27.5 months during the study period. The researchers collected information on women who had mammograms with and without CAD, including whether they were diagnosed with breast cancer within a year of the screening.

According to the study, CAD was associated with more false positivesidentifications of tumors that turned out to be false. It did not improve detection of invasive cancers. Moreover, the cancers detected using CAD were no more likely to be smaller or at a lower stage or to have less lymph node involvement than those detected without CAD. The results were the same after adjusting for patient age, breast density, use of hormone replacement therapy, and other factors that might influence mammography findings.

The authors point out that CAD costs Medicare more than $30 million a year. "As currently implemented in U.S. practice," they write, CAD appears to increase a woman's risk of being recalled for further testing after screening mammography while yielding equivocal
