Official title

A Prospective Multicenter Matched-pair Clinical Study to Evaluate the Sensitivity and Specificity of ABUS and Digital X-Ray Mammography (XRM) Together as a Breast Cancer Screening Method Compared to XRM Alone in Women With >50% Parenchymal Density.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Hypothesis: A higher sensitivity to breast cancer detection can be achieved in women with dense breast tissue by performing and reviewing results of Automated Breast Ultrasound (ABUS) and Digital X-Ray Mammography (XRM) together as part of routine screening compared to performing and reviewing results of XRM alone. Primary Objective: For the cohort of asymptomatic women who have dense breast tissue, calculate the sensitivity of Digital X-Ray Mammography (XRM) and ABUS together as a breast cancer screening modality and compare it to that of XRM alone. Secondary Objective: For the cohort of asymptomatic women who have dense breast tissue, evaluate the specificity of XRM and ABUS together compared to that of XRM alone; Calculate the negative predictive value (NPV) and positive predictive value (PPV) for XRM and ABUS. Endpoint: Breast cancers detected by radiologists in the clinical screening setting and confirmed by pathology. Study Design: This is a prospective matched-pair clinical study enrolling more than 20,000 women with parenchymal density \> 50% on digital x-ray mammography (XRM). Participants will receive ABUS as an adjunct to XRM. Any abnormal findings, from either XRM or ABUS, will receive appropriate management action consistent with accepted medical standards of care. All evaluation results, diagnosis and treatment outcomes will be recorded. Participants will be followed for one year and those who are not diagnosed with breast cancer at enrollment or during the follow-up interval must undergo an annual mammogram at study completion, the outcome of which will be recorded.
