When a suspicious breast MRI lesion has an ultrasound correlate, it is more likely to be an aggressive cancer, according to a study to be presented during this Wednesday afternoon session.
Researchers from Memorial Sloan-Kettering Cancer Center included 310 MRI exams that had been performed between 2008 and 2011. The exams yielded 350 suspicious lesions for which biopsy was recommended; each patient underwent high-resolution targeted ultrasound, and the histopathological grade of each lesion was recorded.
Dr. Punam Bajaj and colleagues found sonographic correlates for 72% of malignant lesions discovered by breast MRI. Of these, 87% were invasive carcinomas and 13% were ductal carcinomas in situ. The group also found that grade III tumors were more likely to have an ultrasound correlate to the suspicious breast MRI.
