Primary central nervous system lymphoma is a rare extranodal form of non-Hodgkin lymphoma with an aggressive course and unsatisfactory outcome. Historically, whole-brain radiotherapy was the sole treatment for patients with primary central nervous system lymphoma, with high response rates but typically, this did not result in long-lasting remissions. The addition of high-dose methotrexate-based chemotherapy regimens to whole-brain radiotherapy has significantly improved patients' outcome, but has resulted in a higher incidence of late neurotoxicity, particularly in elderly patients. To date, the role of consolidation radiotherapy is controversial, and some investigators have developed alternative strategies aiming at avoiding immediate irradiation or using a reduced radiotherapy dose to the whole-brain with promising results.
