Primary central nervous system lymphoma: Novel precision therapies.

Primary central nervous system lymphoma (PCNSL) is a rare and aggressive form of diffuse large B-cell lymphoma. The frontline treatment with high-dose methotrexate based immunochemotherapy is not curative for the majority of patients. Gene expression profiling and next-generation sequencing have recently provided plethora of data shedding light on pathogenic mechanisms sustain PCNSL and identifying potential vulnerable mechanisms to be explored therapeutically. Here, we review established molecular drivers of PCNSL and targeted drugs that may change the current therapeutic paradigm.
