William F. Symmans is a Senior Professor at The University of Texas MD Anderson Cancer Center. His research focuses on breast cancer biology, pharmacology, and the development of predictive biomarkers for neoadjuvant therapy response. He is internationally recognized for pioneering the Residual Cancer Burden (RCB) index, a validated prognostic tool for event-free survival in breast cancer. His recent work includes a novel statistical framework for surrogate endpoint prediction in neoadjuvant trials, pre-analytical best practices for RNA sequencing from small biopsies, and immune subtyping to identify hormone receptor-positive patients who respond to neoadjuvant immunotherapy, as demonstrated in analyses of the I-SPY2 trial. He also contributed to the DESTINY-Breast11 phase III trial evaluating trastuzumab deruxtecan in HER2-positive early breast cancer.
