Stereotactic body radiation therapy (SBRT) is a specialized and highly targeted method of delivering radiotherapy, or radiation therapy, to treat cancer. This approach, used to treat many solid-tumor cancers, including lung, liver and kidney cancers, can mean greater convenience and quality of life for patients because it involves fewer individual treatments and can help to spare healthy tissue. A new study led by Anurag Singh, M.D., of Roswell Park Cancer Institute presented at the American Society for Radiation Oncology (ASTRO) 2016 Annual Meeting suggests that a single high-intensity SBRT dose can be as effective as three slightly lower doses of radiation.
