,

Adam M. Brufsky, MD, PhD, and Erika P. Hamilton, MD, delve into the most clinically significant genomic tests and biomarker assays employed in HR+/HER2- breast cancer, focusing on BRCA mutations, PI3 alterations, AKT alterations, and PTEN alterations, which play crucial roles in determining prognosis and guiding treatment decisions.
