Dr. Jing Cheng: HDAC Inhibition Offers a Path to High-Quality Survival in HR+ Advanced Breast Cancer
Breast cancer remains the most frequently diagnosed cancer among women worldwide, and the pursuit of novel therapies continues to command global attention. In the setting of HR+/HER2− advanced breast cancer, the introduction of entinostat, a novel histone deacetylase inhibitor (HDACi), marks a significant therapeutic advancement. With a distinctive mechanism of action, entinostat not only extends overall survival (OS) but also demonstrates a favorable safety profile. Its innovative once-weekly dosing schedule enhances treatment convenience and patient adherence. When combined with an aromatase inhibitor, entinostat opens a new chapter in second-line management for patients progressing after CDK4/6 inhibitors, pushing breast cancer treatment toward a more personalized and precision-based era.
