Key clinical point: Among women with BRCA1 sequence variation, magnetic resonance imaging (MRI) surveillance reduces the risk for breast cancer (BC) mortality by 80% and can be offered to those aged 30 years or older.
Major finding: After a mean follow-up of 9.2 years, 344 women developed BC and 35 died due to BC. Among women who did vs did not undergo MRI surveillance, the reduction in BC mortality risk was 80% among those with BRCA1 sequence variation (hazard ratio [HR] 0.20; P < .001) but was not significant among those with BRCA2 sequence variation.
Study details: This cohort study included 2488 women (age ≥ 30 years) with BRCA1 or BRCA2 sequence variation, of which 1756 women underwent at least one MRI screening.
