The Breast European Adjuvant Study Team (BrEAST) is a prominent academic research organization (ARO) and clinical trials data center based at the Institut Jules Bordet in Brussels, Belgium. Founded to manage large-scale, international multicenter clinical trials in breast cancer, BrEAST provides comprehensive services including trial design, data management, and statistical analysis. It serves as a central hub for major global studies, often in collaboration with the Breast International Group (BIG). The organization is instrumental in conducting landmark trials such as HERA, ALTTO, and APHINITY, which have shaped the standard of care for adjuvant and neoadjuvant breast cancer treatments worldwide.
