This study highlights patient interest in and the technical feasibility of offering presurgery BRCA1/2 testing to high-risk patients. Most importantly, these results demonstrate that BRCA1/2 test results significantly affect patients' surgical decision-making. The availability of genetic counseling and testing could serve as a valuable aid to patient decision-making for newly diagnosed breast cancer patients at high-risk for carrying a mutation.
Background: Among newly diagnosed breast cancer patients who are at risk for carrying a BRCA1 or BRCA2 mutation, knowledge of mutation status can influence local breast cancer treatment decisions. Thus, genetic testing at the time of diagnosis is increasingly considered an option for such patients. In this study, we evaluated factors associated with the decision to undergo BRCA1/BRCA2 gene testing at the time of initial breast cancer diagnosis. Methods: Participants were newly diagnosed breast cancer patients who had not yet received definitive local breast cancer treatment and who had a family history consistent with hereditary breast cancer. Participants were offered genetic counseling and BRCA1/BRCA2 testing with results in 2 to 3 weeks. Results: Of 231 patients who referred to the study, 20 (9%) declined the baseline interview, 34 (15%) completed a
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
