Utility of surveillance MRI in women with a personal history of breast cancer

Abstract

PurposeTo determine the utility and rate of biopsy in women with a positive history of breast cancer screened with MRI. MethodsRetrospective review of 491 breast MRI screening examinations in women with a personal history of breast cancer. ResultsIn total, 107 biopsies were performed, an average of 0.09 biopsies per person year. The positive predictive value for biopsies prompted by MRI findings was 0.24 (95% C.I. 0.10–0.38). Eight of the nine subsequent cancers were initially identified on screening MRI alone. ConclusionSurveillance MRI in breast cancer survivors may increase detection of subsequent cancers while increasing rate of biopsy.
