Malmö Breast Tomosynthesis Screening Trial
Mammography is the only approved method for breast cancer screening, but not all tumors can
be detected with mammography. The main reason is overlapping structures that can either
mimic or hide a tumor on a 2-dimensional image like mammography. Digital breast
tomosynthesis, (DBT) is a 3-dimensional x-ray technique that has been developed during the
last years. A tomographic technique like DBT, which reduces or eliminates the detrimental
effect of over- and underlying tissue, can probably help to find more tumors. This study
aims to investigate whether more breast cancers can be detected with DBT compared to full
field digital mammography (FFDM) in population invited to screening.
Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Prevention
Number of breast cancers detected by DBT
The number of breast cancers detected by DBT will be compared with the number detected by DM. A follow-up period of 24 months after the intervention period will provide information on the actual numbers of breast cancers in the study population through record linkage with the Swedish Cancer Registry. Sensitivity and specificity for breast cancer detection will be assessed for DBT and BT respectively.
