Multiple Myeloma of the Central Nervous System: 13 Cases and Review of the Literature

Abstract EN

Central nervous system involvement is a rare complication of multiple myeloma with extremely poor prognosis as it usually fails to respond to therapy.

We present 13 cases diagnosed at two centers in Budapest and review the current literature.

The majority of our cases presented with high-risk features initially; two had plasma cell leukemia.

Repeated genetic tests showed clonal evolution in 3 cases.

Treatments varied according to the era, and efficacy was poor as generally reported in the literature.

Only one patient is currently alive, with 3-month follow-up, and the patient responded to daratumumab-based treatment.

Recent case reports show promising effectivity of pomalidomide and marizomib.
