ASCO 2023 | Results from the sub analysis of the AURORA trial

Elisa Agostinetto, MD, Institut Jules Bordet, Brussels, Belgium, details the sub-analysis of the AURORA trial (NCT02102165), a molecular screening initiative led by the breast international group (BIG). For patients with hormone receptor-positive, HER2-negative metastatic breast cancer, CDK4/6 inhibitors combined with endocrine therapy is the standard of care (SOC) in the first-line setting. The aim of the sub-analysis was to identify the clinical, pathological, and molecular trends linked with prognosis in these patients who do not benefit from the SOC. Patients with a primary endocrine resistance had a significantly shorter progression-free survival (PFS) compared to patients who are endocrine sensitive/naïve to therapy. Certain mutations were also linked with a shorter PFS, such as in TP53 and ESR1, which can aid in the formation of a clinical trial to test alternative treatment methods. This interview took place at the American Society of Clinical Oncology (ASCO) 2023 Annual Congress in Chicago, IL.
