- Ages 30 to 85 years
- Women only
- Healthy volunteers accepted
- Adult, Older adult
Who may be able to join
- -Asymptomatic women, ages 30-85, with a personal history of breast cancer who have had at least one routine mammogram since treatment.
Who cannot join
- Women with a history of prior iodinated contrast reaction
- Women with implant(s) in the breasts to be screened (as this creates artifacts and diagnostic performance of imaging in women with implants likely does not generalize to those without implants, and the sample size with implants would be too small to infer conclusions)

About this study
Official title: Improving Surveillance of Women With Personal History of Breast Cancer Using Contrast-Enhanced Mammography (CEM)
This is a prospective clinical trial that will examine if contrast-enhanced mammography substantially improves breast cancer detection compared to mammography with tomosynthesis, with minimal increase in false-positives, in women with a personal history of breast cancer.
Read the detailed description
The investigators expect to show in a prospective clinical trial that, in women with a personal history of breast cancer, contrast-enhanced mammography substantially improves breast cancer detection compared to mammography with tomosynthesis, with minimal increase in false positives. The investigators expect a substantial increase in node-negative invasive cancers in particular. Because DBT will be interpreted first by one reader, and CEM will be interpreted first, and independently, by a second reader, there will also be an assessment of performance of tomosynthesis alone or CEM alone in this population. Participants will be invited to three rounds of annual screening with CEM. CEM must be performed at the time of or within 6 weeks of routine annual mammogram with tomosynthesis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Contrast-enhanced mammogramDevice
Contrast-enhanced mammography (CEM) is a new FDA-approved exam that is similar to magnetic resonance imaging (MRI) in depicting breast cancers due to increased and leaky blood vessels. Contrast-enhanced mammography is used as an adjunct following mammography and/or ultrasound examinations to localize a known or suspected lesion.
| Study group | Role | What they receive |
|---|---|---|
| Contrast-enhanced mammogram | Experimental | All women will receive both 3D mammography and contrast-enhanced mammography for breast cancer screening; the order of interpretation will vary for each of two radiologists Receives: Device: Contrast-enhanced mammogram |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cancer Detection
Number of participants with cancer detected with contrast-enhanced mammography compared to tomosynthesis. Number of patients recalled for additional testing by each imaging test who do not have cancer (false positives). Outcomes will be assessed for both prevalence and incidence screens.
Measured: 48 months
Secondary outcomes (1)
Reader Validation
Reader validation will be performed at study conclusion: number of cancers detected with contrast-enhanced mammography or tomosynthesis.
Measured: 48 months
