Abstract

To determine if breast MRI is useful for detecting additional or invasive sites of disease in patients initially diagnosed with pure DCIS. A retrospective review of women diagnosed with pure DCIS who underwent a breast MRI for evaluation of extent of disease was performed at a single institution from January 2013 to April 2015. Data analysis included imaging (mammography, ultrasound and MRI) and pathology characteristics (histology and biomarker status) of the primary DCIS as well as descriptors for the additional sites of disease incidentally found by breast MRI. A total of 108 patients were diagnosed with pure DCIS during this time period. A breast MRI for staging was recommended for all patients. 76 patients had an MRI performed, ages ranging from 38 to 79 years old (median, 53 years); sizes ranging from 0.3 to 10cm (mean, 2.2cm). A total of 52 patients (68%) either had suspicious new finding(s) (n=27, 36%) or bigger tumor size than originally visualized on mammography (n=43, 57%). A total of twenty-seven patients (36%) had other MRI findings suspicious for additional sites of disease in either breast (four in the ipsilateral breast and twenty-three in the contralateral breast). From this group of patients, twenty-three (85%...Continue Reading
