Abbreviated Breast MRI and Digital Tomosynthesis Mammography in Screening Women With Dense Breasts

Asymptomatic Clinical Trial

Official title: Comparison of Abbreviated Breast MRI and Digital Breast Tomosynthesis in Breast Cancer Screening in Women With Dense Breasts

Status Active, not recruiting

Clinical Trial Summary

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.

Clinical Trial Description

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. ;
