Abstract
Radiation therapy has been proven to be highly effective in the treatment of lymphoma. With increasing rates of long-term survival, the reduction in toxicity has gained importance. The evolving understanding of the diseases’ biology, as well as technical and conceptual advances, allows for a precise and individualized application of irradiation. Smaller treatment fields and safety margins make it possible to spare healthy neighbouring tissue (organs at risk). The International Lymphoma Radiation Oncology Group (ILROG) has developed several guidelines to optimize radiotherapy treatment in lymphoma patients. Since its introduction in 2013, involved site radiotherapy (ISRT) has been adopted as the standard of care in most treatment regimens in adult lymphoma. This article serves as a summary of the current ILROG guidelines, also considering contemporary developments and possible future directions.
