Prognostic Scoring System for Primary CNS Lymphomas: The International Extranodal Lymphoma Study Group Experience

Abstract

Age, PS, LDH serum level, CSF protein concentration, and involvement of deep structures of the brain were independent predictors of survival. A prognostic score including these five parameters seems advisable in distinguishing different risk groups in PCNSL patients. The proposed score and its relevance in therapeutic decision deserve to be validated in further studies.
