Biennial CEM in Women With a Personal History of Breast Cancer

Summary

This is a prospective clinical trial that will examine if biennial contrast-enhanced mammography added to annual 3D mammography (tomosynthesis) substantially improves breast cancer detection with minimal increase in false-positives, in women with a personal history of breast cancer.

Full Description

The investigators seek to determine if improved breast cancer detection is maintained with biennial contrast-enhanced mammography (CEM) added to annual digital breast tomosynthesis (DBT) with overall fewer false positives than from annual DBT plus CEM. The investigators will offer biennial CEM exams for eligible patients. Enrolled participants will have a baseline CEM exam with their routine DBT exam, and then have another CEM exam 24 months after their baseline CEM exam and then again at 48 months. Participants will continue to have their annual DBT exams during this time as a part of their usual care. Two radiologists (one primary) will evaluate each pair of examinations by sequentially interpreting each of DBT and CEM in opposing order (primary reader DBT then CEM and secondary reader CEM then DBT), initially blinded to the other modality. We expect that with biennial screening, at least a similar number of cancers will be detected with CEM (and possibly more that were occult on the DBT-only screen 12 months prior), with a similar incremental false-positive rate and at least similar (if not improved) overall positive predictive value (PPV1).

Eligibility Criteria

Inclusion Criteria:

Asymptomatic women, ages 30-79, with a personal history of breast cancer who are at least one year out from any breast cancer surgery and/or treatment and are scheduled to have a routine annual mammogram with tomosynthesis (DBT).

Exclusion Criteria:

Women with a history of prior moderate or severe iodinated contrast reaction [only those with a prior mild reaction that can be managed by pre-medication AND with and a strong desire to participate will be allowed to participate. However, among these women with a mild sensitivity, if they are allergic to Benadryl (one of the premedications), they will be excluded].
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.
Women who have had bilateral mastectomy
Women with a history of kidney failure or estimated glomerular filtration rate (eGFR) < 45 mL/min
Pregnancy or lactation
Women actively being treated for cancer of any type with chemotherapy
Having only one kidney
Women with stage 4 metastasis to visceral areas or brain
Women who have a screening breast MRI exam within 24 months prior to the current round of CEM.
Women who had a CEM exam within the prior 23 months
