Radiation therapy was first used for the treatment of lymphoma more than a century ago, within just a few years of the discovery of x-rays by Roentgen. The first reports included patients with Hodgkin disease and the non-Hodgkin lymphomas.1,2 The responses to x-ray exposure at times were described as ‘almost magical’ and early radiologists recognized that curative treatment programs for these diseases might be developed. However, they also appreciated a need for a better understanding of the disease entities and better radiation therapy technology to achieve these goals.
