Primary Central Nervous System Diffuse Large B Cell Lymphoma (PCNS-DLBCL)

PCNS-DLBCL is a rare extranodal non-Hodgkin lymphoma that primarily affects the brain, spine, or vitreoretinal space. The prognosis for PCNS-DLBCL is significantly worse than that for its systemic counterpart. Understanding how and where this tumor initiates, and how it survives or depends on the microenvironment of the CNS is key to understanding the underlying biology and identifying reliable biomarkers for selecting personalized therapy or for biologically directed therapy that could improve the cure rate of CNS lymphomas.
