Key clinical point: Preoperative magnetic resonance imaging (MRI) of the breast increased mastectomy rates but did not affect the local recurrence and overall survival (OS) rates in patients with breast cancer (BC) who were eligible for breast-conserving surgery (BCS).
Major finding: Among BCS-eligible patients, surgical procedure was changed to mastectomy in 8.3% vs 0.4% of patients in the MRI vs routine radiologic exam group, respectively. There was no difference in local recurrence-free survival (hazard ratio [HR] 0.72; log-rank test P = .7) and OS (HR 1.37; log-rank test P = .8) between both patient populations.
Study details: Findings are from the phase 3 BREAST-MRI study including 524 patients with stage 0-III BC who were eligible for BCS and were randomly assigned to undergo preoperative MRI or radiologic exam routine with mammography and ultrasound.
