This session explores the evolving role of RAS in precision oncology, from the biology of RAS mutations to the expanding landscape of targeted therapies. Through expert presentations, real-world case discussions, and interactive audience polling, participants will examine best practices for RAS biomarker testing across solid tumors, including lung, colorectal, and pancreatic cancers. The session will highlight practical considerations for tissue and liquid biopsy, strategies to address testing gaps, and the importance of multidisciplinary collaboration to ensure timely identification of patients who may benefit from RAS-targeted therapies.
Webinar presenters David Braxton, MD, Chief of Molecular Pathology Services, Hoag Family Cancer Institute & Hoag Memorial Hospital Presbyterian, and Carlos Becerra, MD, Research Director for Medical Oncology, Margaret Given Larkin Endowed Chair for Developmental Cancer Therapeutics, Hoag Memorial Hospital Presbyterian.
