Abstract:
In the present study, we investigated the effects of immunophenotyping on prognosis of diffuse large B cell lymphoma (DLBCL) with central nervous system (CNS) relapse treated with rituximab-CHOP (R-CHOP). CNS relapse occurred in 9.5% of DLBCL patients. At the diagnosis of DLBCL, CD25 was detected in 14.3% of cases. CD25 positivity correlated with an advanced stage, higher R-IPI, higher CNS-IPI, the presence of B symptoms, the presence of extranodal involvement >1, and bone involvement. Moreover CNS relapse was more frequently observed in patients with CD25+ than in those with CD25-. The univariate analysis showed that an advanced stage, high-risk R-IPI, high-risk CNS-IPI, bone involvement, and CD25+ were associated with shorter overall survival (OS). The multivariate analysis confirmed that CD25+ and high-risk CNS-IPI were independent adverse prognostic factors for shorter OS. A Kaplan-Meier analysis revealed the potential of CD25+ as a prognostic factor in patients with CNS relapse and that it correlated with shorter survival. The present results showed that the expression of CD25 in DLBCL patients with CNS relapse was associated with the patient prognosis independent other prognostic factors. The establishment of a treatment strategy for CNS relapse patients with CD25+ DLBCL cells is needed to improve poor outcomes.
