Central nervous system involvement in mantle cell lymphoma

Area of Science:

• Hematology
• Oncology
• Neurology

Background:

• Extranodal involvement, including the central nervous system (CNS), is a frequent occurrence in mantle cell lymphoma (MCL).
• The precise incidence, risk factors, and prognostic implications of CNS involvement in MCL remain subjects of ongoing research and debate.

Purpose of the Study:

• To investigate the incidence, risk factors, and outcomes associated with central nervous system (CNS) involvement in patients diagnosed with mantle cell lymphoma (MCL).
• To identify clinical and biological predictors of CNS involvement in MCL.

Main Methods:

• Analysis of clinical, biological, and prognostic data from 82 patients with mantle cell lymphoma (MCL).
• Evaluation of risk factors for CNS involvement and overall prognosis.
• Multivariate analysis to identify independent predictors of CNS spread.

Main Results:

• Eleven patients (13.4%) developed CNS involvement, with a 5-year actuarial risk of 26%.
• Predictors of CNS involvement included blastoid histology, high Ki-67, elevated lactate dehydrogenase (LDH), and intermediate- or high-risk International Prognostic Index (IPI).
• Histological subtype and serum LDH remained significant predictors in multivariate analysis. Median survival after CNS involvement was 4.8 months.

Conclusions:

• This study confirms a high incidence of CNS involvement in mantle cell lymphoma (MCL) patients.
• The findings underscore the need for treatments specifically designed to prevent CNS complications in MCL.
