Incidence and characterization of secondary CNS lymphoma in 1972 patients with DLBCL: a Danish nationwide cohort study.

ABSTRACT:

Abstract

Secondary central nervous system lymphoma (SCNSL) is a rare manifestation of diffuse large B-cell lymphoma (DLBCL) with a poor prognosis. We present updated data from a nationwide study on the incidence and clinical characteristics of SCNSL. The incidence of SCNSL was calculated considering death or relapse without SCNSL as competing risks. Risk factors associated with SCNSL were identified using a cause-specific Cox proportional hazards model. A total of 1972 patients with DLBCL were included, of which 68 (3.4%) experienced SCNSL at the first relapse. The crude 1- and 2-year cumulative incidence of SCNSL was 2.0% (95% confidence interval [CI], 1.5-2.7) and 2.6% (95% CI, 2.0-3.4), respectively. For patients with a high-risk central nervous system international prognostic i
