The Radiation Therapy Oncology Group (RTOG) was established in 1967 as a cooperative effort of physicians, physicists, and biostatisticians to pursue clinical investigations designed to increase survival and improve the quality of life of patients with cancer. Over 350 academic and community-based facilities in the United States, Canada and internationally participate in RTOG clinical trials, including nearly 90% of all National Cancer Institute designated comprehensive and clinical cancer centers. Since its inception, RTOG has opened more than 460 protocols, enrolled over 75,000 patients, and published more than 700 papers reporting the results of its findings.
The RTOG is a dynamic multidisciplinary group with vigorous participation by physicians and other researchers from over 300 of the leading academic and community medical facilities in the United States, Canada and internationally, including nearly 90 percent of all NCI-designated comprehensive and clinical cancer centers and many of the major academic and regional centers of Canada. This participation includes leadership from medical oncologists, surgical oncologists, pathologists, and laboratory scientists as well radiation oncologists. All Group research efforts seek to be transformational in nature, with the goal of improving the quantity and quality of survival of cancer patients.
