Molecular Breast Imaging and Digital Breast Tomosynthesis in Screening Patients With Dense Breast Tissue

Breast Carcinoma Clinical Trial

Official title: Density MATTERS [Molecular Breast Imaging (MBI) And Tomosynthesis To Eliminate the ReServoir]

Status Active, not recruiting

Clinical Trial Summary

This study compares molecular breast imaging (MBI) and digital breast tomosynthesis (DBT) in screening patients with dense breast tissue. Breast imaging may help doctors find breast cancer sooner, when it may be easier to treat. Molecular breast imaging (MBI) uses an injection of a small amount of radioactive material that is taken up in tissues of the body that are actively changing, such as breast cancer. A specialized camera, called a gamma camera, takes pictures of the gamma rays emitted by this material. MBI may detect cancers that are not visible on mammograms. This study may help researchers determine how MBI testing compares to DBT screening.

Clinical Trial Description

PRIMARY OBJECTIVE: I. To compare the rate of detection of invasive cancers between digital breast tomosynthesis (DBT) alone versus (vs.) the combination of DBT with supplemental MBI at year 0 screening. SECONDARY OBJECTIVES: I. To compare the invasive cancer detection rates of DBT alone vs. MBI alone at year 0 screening. II. To compare the screening performance metrics of sensitivity, specificity, recall rate, biopsy rate, positive predictive value and negative predictive value for DBT and MBI. III. To compare tumor characteristics of all cancers (invasive and noninvasive) detected on DBT and MBI, including size, nodal status, and molecular subtype. IV. To assess the reduction in advanced cancer rate with incorporation of MBI screening by comparing advanced cancer rate observed at year 1 screening relative to that at year 0. V. To assess the rate of interval cancers with incorporation of MBI screening. VI. To examine the relative performance of DBT and MBI within subgroups categorized by breast cancer risk. OUTLINE: Participants undergo DBT and MBI at year 0 and year 1 screening. ;
