Study information
Scientific title
A non-randomised interventional study comparing TOMosynthesis with digital MammographY in the UK NHS Breast Screening Programme
Acronym
TOMMY trial
Study hypothesis
The trial will compare the accuracy of digital breast tomosynthesis (DBT) with standard digital full field mammography (FFDM) in the diagnosis of breast cancer.
A limitation of standard mammography is that overlapping dense fibroglandular tissue in normal breast tissue can decrease the visibility of malignant abnormalities, or mimic abnormalities. DBT is a newly developed three dimensional (3D) imaging technique that has the potential to improve the accuracy of mammography by reducing interference from tissue overlap and facilitating differentiation between malignant and non malignant features.
The aim of the trial is to assess whether DBT could improve upon digital mammography as a screening tool, particularly in certain groups of women e.g. those with a family history of breast cancer, or women with dense breasts. The diagnostic accuracy of DBT, FFDM and DBT+FFDM will be evaluated in an independent retrospective reading study in and compared to the final clinical outcome for each case.

Condition
Topic: National Cancer Research Network; Subtopic: Breast Cancer; Disease: Breast
Intervention
Participants will be recruited over a 15-18 month period from six UK Breast Screening Centres. This should provide sufficient cancer cases to compare the sensitivity and specificity of the three imaging modalities.
Participants in the trial will have a standard two-view (MLO and CC) digital mammography examination of each breast and a two-view (MLO and CC) digital breast tomosynthesis examination of each breast. The digital mammogram and tomosythesis imaging will be acquired during the same breast compression
