Genetic Testing in Metastatic Breast Cancer in the USA: A Podcast

This podcast highlights the importance of genetic testing in patients with metastatic breast cancer, with a specific focus on germline or inherited breast cancer susceptibility gene (BRCA) mutations. In the USA, national guidelines recommend that all patients with recurrent or metastatic breast cancer should be offered genetic testing for germline breast cancer susceptibility gene 1 or 2 (BRCA1 or 2) mutations to identify patients potentially suitable for treatment with a poly(ADP-ribose) polymerase inhibitor. However, a retrospective study indicated that only 43% of patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative advanced breast cancer who may be eligible for genetic testing have undergone germline BRCA1 or 2 testing. Therefore, a large national effort is required to offer genetic testing to more patients with recurrent or metastatic breast cancer. The aim of this podcast is to provide physicians with information to support the early engagement of patients in discussions about genetic testing, and guidance on how to manage patient concerns about the potential implications of testing. Here, a healthcare professional discusses germline genetic testing with a patient advocate and answers questions regarding the importance of testing in patients with metastatic breast cancer. Furthermore, the authors discuss what it means to receive a positive or negative result for a germline BRCA mutation and the impact this may have on the patient and their family members. Overall, the authors emphasize the importance of healthcare professionals providing every patient with metastatic breast cancer with the relevant information about genetic testing so that patients can make informed decisions.
