Key clinical point: Digital breast tomosynthesis (DBT) reduced the likelihood of advanced breast cancer (BC) diagnosis compared with digital mammography in women with extremely dense breasts and a high risk for BC.
Major finding: Overall screening outcomes per 1000 examinations were similar with DBT vs digital mammography for interval invasive cancer (difference −0.04; 95% CI −0.14 to 0.06); however, the advanced cancer detection rate was lower in women with extremely dense breasts and a high BC risk (difference −0.53; 95% CI −0.97 to −0.10).
Study details: Findings are from a cohort study including 504,427 women with no history of BC or mastectomy who underwent 1,003,900 digital mammography screening examinations or 374,002 DBT screening examinations.
Disclosures: This study was funded by Patient-Centered Outcomes Research Institute, National Cancer Institute, and other sources. Some authors declared receiving grants, consulting fees, or royalties from or serving as consultants or on the editorial board for several sources.
