In this episode of Blood Cancer Talks, hosts Eddie, Ashwin, and Raj welcome two distinguished experts to explore the cutting-edge field of circulating tumor DNA (ctDNA) in B-cell lymphomas. Dr. David Russler-Germain, a lymphoma clinician from Siteman Cancer Centre at Washington University in St. Louis, returns as a familiar voice to the podcast audience. Joining him is Dr. Ash Alizadeh, the Moghadam Family Professor of Medicine, Oncology, and Hematology at Stanford University and leader of the Cancer Genomics Program at Stanford Cancer Institute. Dr. Alizadeh has been instrumental in advancing our understanding of lymphomagenesis and lymphoma genetics over the past two decades, pioneering multiple ctDNA techniques that are revolutionizing cancer care. Together, they discuss the transformative potential of ctDNA technology in B-cell lymphomas, particularly DLBCL, covering everything from the technical evolution of biomarker detection to groundbreaking clinical data that may reshape how we monitor and treat these aggressive cancers.
