Nearly 500,000 patients in the United States were treated withradiation in 1990,1 making radiotherapy one of the most widelyused treatments for cancer. In this article we discuss advancesthat have occurred since the subject of radiation oncology waslast reviewed in the Journal, over a decade ago.2 We begin bysummarizing the biologic responses of cells to radiation, particularlyas they relate to the development of new therapies. We thendiscuss developments in the physics of radiation therapy, especiallythe influence of high-speed computers and graphics displayson the accuracy of radiation treatment. Finally, we discussclinical advances . . . [Full Text of this Article]
