Résumé

Post-transplantation lymphoproliferative disease (PTLD) is a serious complication associated with Epstein-Barr virus (EBV) infection after hematopoietic stem cell transplantation (HSCT). Although anti-CD-20 therapy is now used as a preemptive strategy for EBV reactivation, PTLD still occurs in some patients. Here we analyzed outcomes and risk factors associated with PTLD transformation in 208 HSCT recipients who were diagnosed with EBV-DNAemia and received at least 1 course of rituximab. The median patient age was 42.52 years (range, 8.35 to 74.77 years), and the median duration of follow-up was 47.33 months (range, 3.18 to 126.20 months). The 2-year overall survival of the entire cohort was 62.8 (95% confidence interval [CI], 56.4 to 69.9), and the 2-year cumulative incidence function of PTLD was 6.3% (95% CI, 3.5% to 10.1%), for a median follow-up of patients diagnosed with PTLD of 37.85 months. Multivariable analysis identified 4 risk factors associated with PTLD: HSCT from an unrelated donor, recipient HLA-DRB1*11:01, fever at diagnosis of EBV infection, and donor-recipient sex-mismatched HSCT. The presence of more than 2 of these risk factors was associated with an increased risk of developing PTLD. This retrospective study identifies risk factors associated with PTLD in EBV-infected patients after HSCT and defines patient subgroups that may benefit from intensified preemptive strategies.
