• Adjuvant anthracycline- plus taxane-based chemotherapy (T-AC) improves survival outcomes in high-risk, early-stage, hormone receptor (HR)-positive, HER2-negative breast cancer patients.
• Patients with recurrence scores (RS) of 31 or greater, determined by the OncotypeDX test, experienced significant benefits from T-AC compared to taxane-based chemotherapy alone (TC).
• The addition of anthracyclines was associated with improved distant recurrence-free interval, distant recurrence-free survival, and overall survival at five years.
• While showing promise, the use of anthracyclines requires careful consideration of potential long-term risks, including cardiotoxicity and hematologic malignancies.
