Surveillance Imaging Modalities for Breast Cancer Assessment

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the effectiveness of surveillance breast MRI compared to mammography alone in women with a personal history of breast cancer

Detailed Description
-----------------
Our overall aim is to find out how well MRI works compared with mammography for surveillance in women who have previously had breast cancer. Specifically, our goals are to: Understand doctors' and patients' experiences with surveillance mammography and MRI Provide evidence on which outcomes are more or less likely to occur Develop patient decision aids to help women and their doctors choose the surveillance method that is right for them How we will conduct the study: We will work with patients, doctors, policy makers, advocacy groups, and researchers to improve surveillance for women who have a personal history of breast cancer. Through focus groups with patients and interviews with doctors, we will gain insights into women's experience with surveillance mammography and MRI. We will also compare mammography to MRI using data from the Breast Cancer Surveillance Consortium-the largest collection of breast cancer surveillance data in the nation. We will use data from more than 13,000 women diagnosed with breast cancer between 2005 and 2012 to determine how well each test works. We will measure the tests' effectiveness at finding second cancers, and estimate the likelihood of different outcomes. We will also determine whether one test appears to work better than the other to detect second breast cancers among different groups of women. We will then develop patient decision aids to help women and their doctors make more-informed choices about surveillance. What we hope to achieve: We hope this study will improve medical decision making and care for the 3 million women in the United States who have a history of breast cancer. Specifically, our results will help women and their doctors make clearer, better choices about the surveillance method that is right for them.
