Survival outcomes for patients with HR+/HER2- mBC remain suboptimal, despite first-line treatment strategies with endocrine therapy (ET). Greater understanding of the biology of HR+/HER2- mBC, including the role of biomarkers like ESR1 mutations, and the development of biopsy techniques for early mutation detection, have paved the way for personalized treatment approaches. In this 45-minute activity, medical oncologists Sara Hurvitz, MD, and Hope Rugo, MD, discuss key concepts in integrating these evidence-based advancements into clinical practice. They share their thoughts about selecting personalized treatment based on biomarkers, utilizing liquid biopsy techniques to guide therapy for ET resistance, and applying the latest evidence to overcome ET resistance and optimize patient outcomes.
