Dr. Paul Nguyen, Program Chair, invites you to join us virtually from April 9-11 for the 2025 ASTRO Annual Refresher Course! This course provides a comprehensive review of the latest treatment methods and core competencies for the major disease sites, with a look at the emerging trends and technologies that may impact daily practice. We've got sessions on the major disease sites, three eContouring sessions and onDemand access is included with registration. The Refresher onDemand gives you access beyond the live course dates to content presented by leading experts in the treatment of cancer. New for 2025, there is a physics lecture on protons and heavy ions, a lecture on radiobiology of benign disease and two bonus onDemand presentations on pediatrics and vulvar and vaginal cancers!
