This article reviews radiation techniques including field arrangements, anatomic borders, and doses for the treatment of Hodgkin's disease when radiotherapy is being used as the sole treatment and when it is part of a planned combined modality program with chemotherapy. We describe the techniques currently in use at Duke University Medical Center. Particular emphasis is placed on the evidence regarding the appropriate extent of the treatment field and the doses of radiation necessary to achieve local control. These issues assume increasing importance as we attempt to maintain high cure rates for Hodgkin's disease but lower the frequency of serious long-term complications.
