09:15 – 10:00	Keynote Lecture Moderator: Wing-hong Kwan Proton versus Photon Radiotherapy for Head and Neck Cancer – The Journey to a New Standard of Care Steven J. Frank Executive Director, Particle Therapy Institute Department of Radiation Oncology, Division of Radiation Oncology The University of Texas MD Anderson Cancer Center USA Steven J. Frank, MD, is an endowed tenured professor of Radiation Oncology, holds the Bessie McGoldrick Professorship in Clinical Research, and is a fellow of the ABS, ACR, and ASTRO. Dr. Frank is the Executive Director of the Particle Therapy Institute and Deputy Head of Strategy for the Division of Radiation Oncology. Dr. Frank is amongst the first, if not the first, to use IMPT to treat head and neck tumors, and he is the Principal Investigator of an NIH/NCI/Hitachi-sponsored multi-institutional Phase II/III randomized trial in advanced stage oropharyngeal cancer that compares outcomes after chemoradiation given by IMRT versus IMPT. Dr. Frank has over 300 peer-reviewed publications, has authored many book chapters and has recently published the first textbook on Proton Therapy. Dr. Frank's lab is studying the biologic enhancement factor of proton therapy and FLASH radiotherapy for both head and neck and prostate cancer, as well as MRI-Assisted Radiosurgery (MARS) as the next generation of prostate brachytherapy. Dr. Frank's expertise in MRI radiotherapy has led to the development and FDA approval of multiple novel positive-contrast implantable markers for use in MRI-guided LDR and HDR prostate brachytherapy and external beam radiation therapy. As founder of the company, C4 Imaging, Dr. Frank has developed the MRI marker technology at MD Anderson, has been granted 31 national and international patents, developed three FDA-approved products and has established MRI-Assisted Radiosurgery (MARS) at MD Anderson for the treatment of prostate cancer. He has funding from the NIH, the Prostate Cancer Foundation, the Texas Ignition Fund, Hitachi and MD Anderson, and he has also raised multiple rounds of private equity financing to advance the C4 technology. Dr. Frank has served as the past President and Chairman of the Board of the American Brachytherapy Society and is the 2023 recipient of the Ulrich Henschke Award, the highest honor awarded by the ABS on a practitioner of brachytherapy. Dr. Frank has served as the chair for the head and neck oral boards for seven years and is currently serving on the Radiation Oncology Board of Trustees for the American Board of Radiology.
