PRIMARY OBJECTIVES:
I. 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:
I. 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.
V. 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.

- Screen-detected Invasive Cancer Verified by Pathology [ Time Frame: Up to 1 year ]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 (%).
- Prediction of Breast Cancer (Sensitivity and Specificity) [ Time Frame: Baseline to up to 1 year ]
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.
- Positive Predictive Value (PPV) of Biopsies [ Time Frame: Baseline to up to 1 year ]
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
- Call Back/Additional Imaging/Short-term Follow Rates for DBT and AB-MR [ Time Frame: Baseline ]
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
- Ductal Carcinoma in Situ (DCIS) Detected on Abbreviated Breast-magnetic Resonance (MR) and Digital Tomosynthesis Mammography (DBT) [ Time Frame: Up to 1 year ]
The analysis for will be descriptive. If the Oncotype-DCIS score was performed, the distributions of scores will be tabulated and compared.
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.
- Incident Cancer Rate [ Time Frame: Up to 3 years ]Breast cancer incidence will be estimated. Person-years will be measured.
- Tumor Biologies of Invasive Cancers [ Time Frame: Up to 1 year ]The analysis for will be descriptive. The frequencies of cancer types determined by the NanoString analysis will be tabulated and compared.
- Factors Associated With Willingness to Return for Screening [ Time Frame: Up to 1 year ]Polytomous logistic regression will be used to examine factors associated with willingness to return, including screen result, cancer status, and demographic characteristics.
- Change in Patient-reported Short-term Quality of Life Related to Diagnostic Testing [ Time Frame: Baseline to up to 1 year ]Separate Testing Morbidities Index (TMI) scores will be computed for abbreviated breast-magnetic resonance (MR) and digital tomosynthesis mammography (DBT) after the baseline screen. Scores will be compared using a nonparametric test that accounts for the pairing of scores by participant.
- Willingness to Return for Testing With Abbreviated Breast-magnetic Resonance (MR) Versus Digital Tomosynthesis Mammography (DBT) [ Time Frame: Up to 1 year ]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.
