Prior studies suggest that referral to genetic counseling and completion of genetic testing vary by race\/ethnicity; however, the data are limited.We sought to evaluate patterns of genetic testing and clinical outcomes across race\/ethnicity at a hereditary breast and ovarian cancer center.The medical records for all patients undergoing genetic assessment at a hereditary breast and ovarian cancer center were reviewed and stratified by self-reported race\/ethnicity (non-Hispanic White, Hispanic, non-Hispanic Black, and Asian).A total of 1666 patients met inclusion criteria (non-Hispanic Whites, 1367; Hispanics, 85, non-Hispanic Blacks, 101; Asians, 113).Demographics, patient characteristics, and referral patterns for patients who underwent genetic testing were analyzed using Kruskal-Wallis tests, chi-square test, or Fishers exact tests, stratifying by self-reported race\/ethnicity. Pathogenic mutations and variants of unknown significance (VUS) were reviewed. Outcomes of patients with genetic mutations and personal history of breast and\/or gynecologic malignancies were compared.Non-Hispanic Whites were more likely to be referred due to family cancer history compared to all other ethnicities while Non-Hispanic Blacks, Hispanics, and Asians were more likely to be referred due to personal history of cancer (p<0.001). Non-Hispanic Blacks and Hispanics were more likely to have advanced-stage cancer at the time of genetic testing (p<0.02). Rates of mutations did not differ by race\/ethnicity when Ashkenazi Jewish patients were excluded (p=0.08). Among patients found to have a BRCA1\/2 mutation, Non-Hispanic Whites were more likely to undergo cancer screening and risk-reducing surgery compared with all other ethnicities (p=0.04).Minority patients were more likely to utilize genetic services following a cancer diagnosis and less likely due to family cancer history, suggesting a missed opportunity for mutation detection and cancer prevention in this population. Efforts to eradicate racial\/ethnic disparities in early access to genetic testing and guided cancer prevention strategies are essential.<\/p>\n
