Official title: Assessment of Diagnostic Accuracy and Performance of Digital Breast Tomosynthesis Compared to Mammography ADAPT-Enrich: Recruitment Plan for Initially Asymptomatic Women Referred for Breast Biopsy After Screening Digital Breast Tomosynthesis Exam

Status Terminated

Clinical Trial Summary

The aim of this recruitment plan (ADAPT-Enrich) is to collect image and technical data on both digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM), along with other subject data including histology results from biopsy specimen examination and cancer classification data from initially asymptomatic women referred for clinically indicated breast biopsy based on suspicious DBT screening breast imaging results. These data will be included in a subsequent and prospectively planned pooled analysis described in a separate protocol (ADAPT-BIE) examining superiority of DBT to FFDM for breast cancer diagnosis and other performance measures.

Clinical Trial Description

ADAPT-ENRICH will supplement an on-going program (ADAPT) which consists of 2 additional recruitment plans (ADAPT-SCR and ADAPT-BX) followed by an off-line read of the images and data collected (ADAPT-BIE). This study involves the comparison of two devices that can identify abnormalities in routine breast screening and diagnostic mammography. Mammography is usually done with full-field digital mammography (FFDM), which takes flat, two-dimensional X-ray images of the breast. Doctors use the two-dimensional images to look for cancers and other abnormal tissue. The purpose of this study is to learn more about the accuracy of full-field digital mammography devices and a new mammography device called digital breast tomosynthesis (DBT). DBT is similar to full-field digital mammography, but can also move around the breast to get X-ray images from different angles, which provides a three-dimensional view that doctors can use to look for cancers and abnormal tissue. Subjects will be recruited from an initially asymptomatic population that have been referred for clinically indicated breast biopsy based on suspicious DBT screening breast imaging results. Subjects will undergo a DBT mammogram prior to biopsy. If FFDM was not performed within 30 days, subjects will also undergo FFDM prior to biopsy. Results of biopsy(ies) and histopathology, including lesion characteristics, will be recorded and considered as truth if positive for cancer status. Subjects with negative or benign histological findings will be followed for approximately one year (10-16 months) by FFDM and any additional standard of care practice. ;
