An article comparing cancer detection rates (CDR) for screening digital breast tomosynthesis (DBT) vs full-field digital mammography (FFDM) found that DBT results in “significantly increased CDR”—irrespective of tumor type, size, or grade of cancer. Reviewing consecutive screening examinations performed between October 2012 and September 2014 at a large academic breast imaging practice, Pragya A. Dang and researchers at Brigham and Women’s Hospital in Boston detected 61 cancers in the matched cohort of DBT (n = 9817) and FFDM (n = 14,180) examinations. CDR measured higher with DBT than with FFDM for invasive cancers (2.8 vs 1.3, p =0.01), minimal cancers (2.4 vs 1.2, p = 0.03), estrogen receptor– positive invasive cancers (2.6 vs 1.1, p = 0.01), and node-negative invasive cancers (2.3 vs 1.1, p = 0.02.), respectively. However, the ratio of screen-detected invasive cancers to ductal carcinoma in situ on DBT (3.0) was not significantly different from that on FFDM (2.6) (p = 0.79). Where CDR were not statistically significant for DBT and FFDM, Dang noted: “We were likely underpowered to show a significant difference because of the smaller number of cancers in these subgroups. For instance, CDR of moderately and poorly differentiated invasive cancers, and for all cancer sizes detected with DBT, was nearly twice that of FFDM, even though it was not statistically significant.” As Dang concluded, “our results suggest that integrating DBT into clinical practice may detect overall more cancers than does FFDM, for all tumor sub-types, grades, sizes, and nodal statuses.”
