Osteosarcoma Webinar Series: Amanda Marinoff, MD, a physician-scientist from UCSF will discuss clinical biomarkers for osteosarcoma stratification (cBOSS): Insights from a working group.
Despite decades of research, osteosarcoma remains one of the few pediatric cancers without validated molecular biomarkers to guide treatment. The Clinical Biomarkers for Osteosarcoma Stratification (cBOSS) initiative is an international effort to change that. Modeled after a successful framework in Ewing sarcoma, cBOSS convened experts from North America and Europe to systematically evaluate emerging molecular features with the greatest potential for near-term clinical translation. Through a series of structured sessions, the group assessed the biological plausibility, clinical relevance, and implementation feasibility of candidate classifiers across five domains: genomic, transcriptomic, epigenetic, immune, and circulating analytes. This webinar will provide an overview of the cBOSS approach, key findings to date, including the maturity of circulating tumor DNA and MYC amplification as prognostic tools, and the path forward for incorporating molecular stratification into future clinical trials. The goal: to move beyond one-size-fits-all therapy and build a precision medicine framework for osteosarcoma.
Dr. Amanda Marinoff is a pediatric oncologist and translational researcher at UCSF, where she focuses on developing molecular biomarkers to improve risk stratification and treatment for children and young adults with osteosarcoma. She co-leads the international cBOSS initiative (Clinical Biomarkers for Osteosarcoma Stratification), which brings together experts across North America and Europe to evaluate and prioritize emerging classifiers for clinical use. Her research aims to bridge the gap between genomic discovery and therapeutic application, advancing precision medicine approaches for patients with high-risk disease. Dr. Marinoff earned her medical degree from Harvard Medical School, completed her pediatrics residency at Boston Children's Hospital, and completed her pediatric hematology/oncology fellowship at UCSF Benioff Children’s Hospital. She is an active member of the pediatric solid tumor and early-phase clinical trials groups at UCSF.
