Rituximab increases survival in the rat model of CNS lymphoma. Rats with MRI-confirmed MC116 CNS lymphoma were randomized to treatment groups and followed for survival. The Kaplan–Meier survival curves show that methotrexate (MTX) was ineffective in this model (P=0.18), whereas all rituximab (RTN) groups improved survival compared with control (RTN BBBD [blood–brain barrier disruption], P=0.013; RTN +MTX BBBD, P=0.0042; RTN IV [intravenous], P=0.0049).
