Provider Discussions of Genetic Tests With U.S. Women at Risk for a BRCA Mutation.

Author information

Abstract

INTRODUCTION:

The U.S. Preventive Services Task Force recommends that primary care providers screen unaffected women with a family history of BRCA mutation-associated cancers, but without a personal history of BRCA-related cancer, for referral to genetic counseling and potential genetic testing.

METHODS:

The 2015 National Health Interview Survey was analyzed in January 2017 to determine the rates at which unaffected adult women with a positive family history of BRCA-related cancers, assessed using the Family History Screen-7, reported discussing genetic testing with a provider, using genetic counseling services, and having genetic testing for increased cancer risk. Clinical correlates associated with these outcomes were assessed using multivariable logistic regression (AOR with 95% CI).

RESULTS:

Among unaffected Family History Screen-7 screen-positive women, 9.5% reported discussing genetic testing with a provider, 5.1% reported genetic counseling, and 2.7% reported uptake of genetic testing. Younger women (aged 18-39 and 40-49 years) were more likely to discuss genetic testing than women aged ≥60 years (AOR=1.50, 95% CI=1.09, 2.06 and AOR=1.64, 95% CI=1.15, 2.33, respectively). Women of black race (AOR=1.50, 95% CI=1.09, 2.07) and women with greater than a high school education (AOR=1.85, 95% CI=1.41, 2.43) were more likely to discuss genetic testing than women of white race and women with a high school education or less, respectively. Among a higher risk subgroup with an even stronger family history of BRCA-associated cancers, 18.5% of women reported discussions.

CONCLUSIONS:

Despite a decade-old U.S. Preventive Services Task Force recommendation, few unaffected women at risk for BRCA-associated cancer report discussing genetic testing with a provider.
