Key clinical point: Data from a multi-institutional US database of more than 2.5 million screening mammograms showed that digital breast tomosynthesis (DBT) was superior to digital mammography (DM) for the purpose of breast cancer (BC) screening.
Major finding: Compared with DM, DBT led to significantly higher cancer detection rates (adjusted odds ratio [OR] 1.24), biopsy rate (adjusted OR 1.33), and positive predictive value of recall (adjusted OR 1.33; all P < .001).
Study details: Findings are from a retrospective study including 2,528,063 screening mammograms in 1,100,447 women aged 40-79 years.
Disclosures: This study did not report the source of funding. Some authors declared receiving grants, travel support, consulting fees, or payments from various sources.
