Abstract
PurposeThe contribution of clinical breast exam (CBE) to breast cancer diagnosis in average risk women undergoing regular screening mammography is minimal. To evaluate the role of CBE in high-risk women, we compared BC diagnosis by CBE in BRCA mutation carriers undergoing regular BC surveillance to average to intermediate risk women undergoing regular breast cancer screening.MethodsA retrospective chart review of all consecutive screening visits of BRCA mutation carriers (January 2012–October 2022) and average to intermediate risk women (November 2016–December 2022) was completed. Women with histologically confirmed BC diagnosis were included. Additional CBE yield for BC diagnosis, defined as the percentage of all BC cases detected by CBE alone, was assessed in both groups.ResultsOverall, 12,997 CBEs were performed in 1,328 BRCA mutation carriers in whom 134 BCs were diagnosed. In 7,949 average to intermediate risk women who underwent 15,518 CBEs, 87 BCs were diagnosed. CBE contributed to BC diagnosis in 3 (2%) BRCA mutation carriers and 3 (4%) non-carriers. In both groups, over 4,000 CBEs were needed in order to diagnose one cancer. In all 3 BRCA mutation carriers BC was palpated during the surveillance round that did not include MRI. In the average to intermediate risk group, 2 of 3 cancers diagnosed following CBE findings were in a different location from the palpable finding.ConclusionsThe contribution of CBE to BC diagnosis is marginal for all women including BRCA mutation carriers. In BRCA mutation carriers, CBE appears redundant during the MRI surveillance round.
