Management and prognosis of 66 patients with B-cell non-Hodgkin lymphoma presenting with initial spinal cord compression: a French retrospective multicenter study

Abstract

Initial spinal cord compression (ISCC) in B-cell non-Hodgkin lymphoma (NHL) is rarely present at diagnosis. We performed a multicenter retrospective analysis of 66 patients with ISCC, including diffuse large B-cell (DLBCL) (70%), follicular (20%), small lymphocytic (6%), marginal zone (2%) and B-cell unclassified (2%) lymphomas, with the aim of describing their management and outcomes, as well as the occurrence of central nervous system (CNS) relapses. All but two patients received cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) or CHOP-like regimens, with rituximab in 61% of cases. Forty-six patients received CNS prophylaxis. The 5-year overall survival and progression-free survival were 78% and 65% for DLBCL, and 60% and 48% for indolent lymphomas, respectively. CNS relapses occurred in four (6%) patients, all with DLBCL and all in the cerebellum. Initial decompressive procedures, intradural involvement, cerebrospinal fluid infiltration and lack of CNS prophylaxis did not influence survival. Adverse prognostic factors were male sex, poor performance status, elevated lactate dehydrogenase and high age-adjusted international prognostic index.
