Could emerging biomarkers redefine how we assess response and recurrence risk in muscle-invasive bladder cancer? To find out, Dr. Charles Turck speaks with Dr. Petros Grivas about the key findings from the phase 3 NIAGARA trial. Together, they explore how perioperative durvalumab impacts circulating tumor DNA (ctDNA) clearance and clinical outcomes, including event-free and overall survival. Their conversation also highlights the prognostic value of ctDNA and the potential for urinary tumor DNA to more closely correlate with pathologic complete response. Dr. Grivas is a Professor in the Division of Hematology and Oncology at the University of Washington School of Medicine, as well as the Clinical Research Division at the Fred Hutchinson Cancer Center, where he's also the Medical Director of the International Program and of local and regional outreach.
