Sustained response to intrathecal rituximab in EBV associated Post-transplant lymphoproliferative disease confined to the central nervous system following haematopoietic stem cell transplant

Abstract

Post-transplant lymphoproliferative disorder (PTLD) in the central nervous system (CNS) is a very rare complication of haematopoietic stem cell transplant (HSCT) and has a dismal prognosis. We report the successful treatment of this disorder with intrathecal rituximab therapy in two children who developed isolated CNS PTLD after HSCT. These children had failed to respond to standard chemotherapy, intravenous rituximab and EBV specific cellular therapy.
