Abstract

The role of breast magnetic resonance imaging (MRI) in the screening of breast cancer survivors with remaining breast tissue is not well studied. We sought to evaluate the outcomes of screening breast MRI in a cohort of breast cancer survivors. A population of patients with history of stage I-IIIa breast cancer and ≥1 MRI a year or later from diagnosis between 2006-2008 were identified using the National Comprehensive Cancer Network data base from two large Boston-area cancer centers. Patient and disease characteristics were obtained from the data base, and medical records were reviewed to identify the index MRI (first eligible), indications, and two-year outcomes. Overall, 647 patients had breast MRI scans during the study period including 342 eligible patients whose index MRIs were done for breast screening purposes. 47/342 (13.7%) were abnormal, and 3.8% (13/342) underwent biopsy, resulting in the detection of 3 cases of locoregional recurrence or new primary breast cancer (0.9%, 95% CI = 0.2%-2.5%). Of 295 patients with a normal index screening MRI, 12 had a breast cancer recurrence diagnosed within 2 years (4.1% 95%CI = 2.1%-7.0%), and 5 of these recurrences were limited to MRI-screened breast tissue. No statistically significant difference in the rate of 2-year locoregional or distant recurrence was observed between patients with an abnormal screening MRI and those with a normal scan. Adjunct single breast MRI surveillance in a general population of breast cancer survivors one year after diagnosis detected few recurrences, and its effect on short-term outcomes was unclear.
