Abstract
The role of radiotherapy in the treatment of lymphoproliferative disorders has evolved over time, particularly with the advent of effective immunochemotherapy regimens and, more recently, with the assessment of response using metabolic imaging techniques, such as positron emission tomography (PET). In the case of diffuse large B-cell lymphoma, this review examines the evidence regarding the usefulness of radiotherapy in localized stages, advanced stages with large masses, and some primary extranodal lymphomas, such as primary testicular and primary mediastinal lymphomas. It also considers the usefulness of radiotherapy in relapsed/refractory patients, either as a bridge to CAR-T therapy or for consolidation after autologous transplantation. Finally, the role of radiotherapy for palliative purposes.
