Abstract
Digital breast tomosynthesis (DBT) increases the sensitivity and specificity of detecting invasive breast carcinoma. Integration into screening raises questions. Should we perform two-view full-field digital mammography (FFDM) and two-view DBT or two-view FFDM and single-view DBT at every screening? DBT is shown to offer greatest benefit in the assessment of a soft tissue lesion. We routinely use two-view DBT in combination mode for all patients recalled from screening for a soft tissue abnormality. The aim of our study is to assess the need for two-view DBT in the detection of breast cancer.
Highlights
Previous research in this centre enabled the introduction of a local protocol of nonbiopsy and discharge of women
Mammography-detected cancers were luminal in 77% (P = 0.03), node negative in 77% (P = 0.005), with ductal carcinoma in situ (DCIS) in 81% (P = 0.007)
We applied our approach to 13 experienced readers assessing 13,694 screening mammograms from a large clinical study where women are categorised as high risk if they have a 5 to 8% 10-year risk computed by a validated risk model and their breast density is in the top decile of the study population
