Primary central nervous system lymphoma (PCNSL) is a rare extra-nodal non-Hodgkin's lymphoma confined to the central nervous system with a diffuse large B-cell lymphoma (DLBCL) histology and is highly prevelant in elderly patients. Whole brain radiotherapy (WBRT) does not provide considerable remission; rather it is highly involved in the development of leukoencephalopathy with delayed neurotoxicity, notably in elderly patients. Standard care for newly diagnosed patients with PCNSL comprised induction with high-dose methotrexate (HD-MTX)-based multi-agent immunochemotherapy, such as R-MPV (rituximab, MTX, procarbazine, vincristine) yielding 70-75% complete response rate, followed by HD-cytarabine consolidation. Consolidation high-dose chemotherapy with the key drug thiotepa supported by autologous stem cell transplant has recently been investigated to replace WBRT in multiple randomized trials, demonstrating non-inferiority to WBRT with less neurotoxicity. Comprehensive genetic analyses have revealed high rates of oncogenic mutations in CD79B and MYD88 genes, the hallmarks for MCD/C5 subtype of DLBCL, leading to constitutive activation of NF-κB signaling pathways in PCNSL. Bruton's tyrosine kinase (BTK), an intermediate kinase downstream to CD79B/MYD88, has emerged as a promising therapeutic target. Furthermore, tirabrutinib, a second-generation BTK inhibitor, has shown substantial activity against relapsed/refractory PCNSL, resulting in its approval in 2020 in Japan. Additionally, other new agents against PI3-kinase and immunotherapies including immunomodulatory agents, immune checkpoint blockade, and CAR-T have been actively tested in clinical trials.

UI	MeSH Term	Description	Entries
D008228	Lymphoma, Non-Hodgkin	Any of a group of malignant tumors of lymphoid tissue that differ from HODGKIN DISEASE, being more heterogeneous with respect to malignant cell lineage, clinical course, prognosis, and therapy. The only common feature among these tumors is the absence of giant REED-STERNBERG CELLS, a characteristic of Hodgkin's disease.
