Hypofractionated radiotherapy refers to a radiation treatment in which the total radiation dose is delivered in either a single treatment or a few treatment sessions (each session is referred to as a fraction). The total treatment time for a hypofractionated radiotherapy is much shorter than the standard radiation therapy. Sterotactic Body Radiotherapy (SBRT) is one type of hypofractionated radiotherapy, and it is rapidly becoming a widely used modality in treating various types of cancer in the world. In this talk, Dr. Timmerman discusses the evolution of the technology propelling the use of SBRT as well as the clinical experience.


Robert Timmerman, M.D. is Professor and Vice Chairman of the Department of Radiation Oncology, at the University of Texas Southwestern Medical Center in Dallas, Texas. After earning a master’s degree in reactor physics, he completed medical school in his home state of South Dakota, followed by a residency in radiation oncology at The Johns Hopkins Hospital. Dr. Timmerman was one of the first researchers in the world to use specialized treatment techniques developed for brain tumors to treat cancer in the body. That technique is currently known as stereotactic ablative radiotherapy (SABR) or, alternatively, as stereotactic body radiation therapy (SBRT). This revolutionary technique relies on highly advanced imaging technology and sophisticated planning software to deliver an extremely potent dose from multiple angles – and it has been shown to offer better cure rates in some instances, particularly for cancers that have spread (metastasized). Dr. Timmerman has championed the use of SABR globally and has served as the lead investigator in several national trials designed to evaluate the efficacy and safety of SABR to treat cancer in the lung, liver, spine, and prostate. Dr. Timmerman currently directs training courses in SBRT both at UT Southwestern and nationally for members of the national Radiation Therapy Oncology Group. He is a highly sought-after guest speaker and has authored or co-authored numerous peer-reviewed articles and textbooks, including the best-selling textbook on SABR/SBRT.
