Abstract & Overview
Primary central nervous system lymphoma is a rare subtype of non-Hodgkin lymphoma that is confined to the brain, leptomeninges, or the eye and is associated with a relatively poor prognosis compared to other extranodal diffuse large B-cell lymphomas. However, methotrexate-based induction chemotherapy followed by consolidative chemotherapy or high-dose therapy and autologous stem cell transplantation is associated with improved survival and reduced neurotoxicity. Aberrant activation of B-cell receptor signaling and activation of nuclear factor kappa beta is a frequent genetic alteration and offers opportunities for targeted therapies in this lymphoma subtype.
