Isolated central nervous system relapse in two adolescents with primary mediastinal large B‐cell lymphoma after treatment with R‐DA‐EPOCH

Abstract

AbstractThe addition of rituximab to standard regimens for primary mediastinal large B‐cell lymphoma (PMBCL) has significantly improved overall survival. However, the optimal management of isolated central nervous system (CNS) relapse and role of CNS prophylaxis remains undefined. We present cases of two adolescents with PMBCL who developed isolated CNS relapses. While isolated CNS relapse may be managed with high‐dose chemotherapy and autologous stem cell transplant with or without CNS radiotherapy, review of these cases and the literature highlight the need for further work to define risk factors for CNS relapse, and identify patients who may benefit from CNS prophylaxis.
