About this study
Official title: Comparison of Abbreviated Breast MRI and Digital Breast Tomosynthesis in Breast Cancer Screening in Women With Dense Breasts
This randomized phase II trial studies how well abbreviated breast magnetic resonance imaging (MRI) and digital tomosynthesis mammography work in detecting cancer in women with dense breasts. Abbreviated breast MRI is a low cost procedure in which radio waves and a powerful magnet linked to a computer and used to create detailed pictures of the breast in less than 10 minutes. These pictures can show the difference between normal and diseased tissue. Digital tomosynthesis mammography is a procedure that uses multiple x-rays pictures of each breast to produce a 3-dimensional rendering of the entire breast. Combined screening with abbreviated breast MRI and digital tomosynthesis mammography may be a better method to screen women with dense breasts.
Read the detailed description
PRIMARY OBJECTIVES:
- To compare the rates of detection of invasive cancers between the initial abbreviated breast (AB)-magnetic resonance (MR) and digital tomosynthesis mammography (DBT).
SECONDARY OBJECTIVES:
- To compare the positive predictive value (PPV) of biopsies, call back rates, and short-term follow up rates after AB-MR and DBT on both the initial and 1 year follow up studies.
II. To estimate and compare the sensitivity and specificity of AB-MR and DBT, using the 1 year follow up to define a reference standard.
III. To compare patient-reported short-term quality of life related to diagnostic testing with AB-MR and DBT using the Testing Morbidities Index.
IV. To compare willingness to return for testing with AB-MRI versus (vs) DBT within the recommended screening interval and explore factors associated with willingness to return for screening.
- To compare the tumor biologies of invasive cancers and ductal carcinoma in situ (DCIS) detected on AB-MR and DBT.
VI. To estimate the incident cancer rate during 3 years following the year-1 AB-MR/DBT when patients return to standard screening.
OUTLINE: Participants are randomized to 1 of 2 arms.
ARM A (DBT, AB-MR): Participants undergo DBT followed by AB-MR for under 10 minutes on the same day or within 24 hours at baseline and then after 1 year.
ARM B (AB-MR, DBT): Participants undergo AB-MR for under 10 minutes followed by DBT on the same day or within 24 hours at baseline and then after 1 year.
After completion of study, patients are followed up at every 6 months for 3 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Screen-detected Invasive Cancer Verified by Pathology
For each modality, the detection rate of invasive cancers is defined as the proportion of participants who had an invasive cancer detected by the modality at baseline and verified by pathology versus the total number of participants. In the out come measures table below, these proportions will be automatically calculated, multiplied by 100, and be presented as percentages (%).
Measured: Up to 1 year
Secondary outcomes (9)
Positive Predictive Value (PPV) of Biopsies
Test Positive (T+): Biopsy recommended by imaging, defined as patients with at least one lesion rated BI-RADS 4 or 5 on image interpretation. Reference Standard Positive (RS+): Pathologically confirmed DCIS or invasive disease resultant from a positive test.
The 95% confidence interval for PPV of biopsy for each modality were derived from the GEE model using the appropriate estimable contrasts with robust standard errors
Measured: Baseline to up to 1 year
Call Back/Additional Imaging/Short-term Follow Rates for DBT and AB-MR
For DBT:
DBT: Call back is defined as having additional views or targeted ultrasound to evaluate DBT findings DBT: short term follow up (STFU) is defined as having at least one lesion rated BI-RADS 3 on DBT DBT: Additional imaging recommendation is defined as having either call back or STFU
For AB-MR:
Ab-MR: Call back does not apply to AB-MR and will not be evaluated Ab-MR: Short Term Follow-up (STFU) is defined as having at least one lesion rated BI-RADS 3 on AB-MR Ab-MR: Additional imaging recommendation is defined as having a STFU
Measured: Baseline
Prediction of Breast Cancer (Sensitivity and Specificity)
Reference standard positive (RS+): breast cancer (invasive or DCIS) detected on the year 0 screening or reported at any time from the year 0 to the year 1 screening.
Reference standard negative (RS-): No breast cancer reported at any time from the year 0 to the year 1 screen.
Incomplete: No Year 1 imaging, and <11 months of patient follow-up (<330 days) after year 0 screen
Positive Test (T+) is defined as the imaging modality result is positive (BI-RADS 3-5), and the location of the finding is matches the location of the cancer indicated by the reference standard.
Negative Test (T-) will be estimated as the fraction of reference standard negative subjects for whom the imaging modality result was negative (BI-RADS 1-2).
95% confidence intervals for the sensitivity and specificity of each modality calculated using the Wilson method.
Measured: Baseline to up to 1 year
Change in Patient-reported Short-term Quality of Life Related to Diagnostic Testing
Testing Morbidities Index (TMI) scores [0 (worst) to 100 (best) scale] will be computed for abbreviated breast-magnetic resonance (MR) and digital tomosynthesis mammography (DBT) after the baseline screen.
Measured: Baseline to up to 1 year
Willingness to Return for Testing With Abbreviated Breast-magnetic Resonance (MR) Versus Digital Tomosynthesis Mammography (DBT)
The proportions of participants willing to return for screening with either test, AB-MRI only, DBT only, or not willing to return for either test will be estimated.
Measured: Up to 1 year
Factors Associated With Willingness to Return for Screening
Polytomous logistic regression will be used to examine factors associated with willingness to return, including screen result, cancer status, and demographic characteristics.
Measured: Up to 1 year
Oncotype-DCIS Scores by Modality
Descriptive Analyses presenting the the distributions of Oncotype-DCIS scores by modality: Ductal carcinoma in situ (DCIS) detected on abbreviated breast-magnetic resonance (MR) and digital tomosynthesis mammography (DBT) A low risk score is less than 39, and a high risk score is 55 or higher. A score of 39 to 54 is intermediate risk.
Measured: Up to 1 year
Incident Cancer Rate
Breast cancer incidence will be estimated. Person-years will be measured.
Measured: Up to 3 years
NanoString Tumor Biologies of Invasive Cancers and Ductal Carcinoma in Situ (DCIS) Detected on AB-MR and DBT
For all invasive cancers detected during the study period, the NanoString PAM50 will be performed. The frequencies of cancer types determined by the NanoString analysis will be tabulated and compared. For DCIS, if the Oncotype-DCIS score was performed, the distributions of scores will be tabulated and compared.
All efforts to obtain NanoString data have been exhausted, therefore we have no data available to report.
Measured: end of study

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Feb 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Screen-detected Invasive Cancer Verified by Pathology (time frame: Up to 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02933489, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Feb 2026.
