Disparities in Hereditary Genetic Testing in Patients with Triple Negative Breast Cancer.
Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer that disproportionately affects younger females, non-Hispanic Black women, Hispanic women, and women with the BRCA1 gene mutation. Hereditary genetic testing is particularly important in this population to assess preventative and treatment strategies, however access to genetic testing is variable. A qualitative review was performed to evaluate barriers to genetic testing for patients with TNBC. Mutations common in breast cancer are reviewed along with updated guidelines on management strategies, including the ability to include PARP inhibitors as a treatment strategy. Barriers to genetic testing are multifactorial, with non-Hispanic Black women being tested less often than other groups. The disparity is even further represented by the limited number of non-Hispanic Black patients with TNBC who receive risk-reducing surgery or targeted systemic therapy. Eliminating barriers to genetic testing can allow us to support guideline-directed care for patients with TNBC at higher risk for genetic mutations.
期刊介绍:
Clinical Breast Cancer is a peer-reviewed bimonthly journal that publishes original articles describing various aspects of clinical and translational research of breast cancer. Clinical Breast Cancer is devoted to articles on detection, diagnosis, prevention, and treatment of breast cancer. The main emphasis is on recent scientific developments in all areas related to breast cancer. Specific areas of interest include clinical research reports from various therapeutic modalities, cancer genetics, drug sensitivity and resistance, novel imaging, tumor genomics, biomarkers, and chemoprevention strategies.
