Abstract: Objective:To evaluate clinical outcomes of autologous (auto-HSCT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for angioimmunoblastic T-cell lymphoma (AITL) .
Methods:From June 2007 to June 2017, clinical data of AITL patients who underwent HSCT in eight hospitals were assessed retrospectively.
Results:Of 19 patients, 13 male and 6 female with a median age of 50 (32-60) years old, 12 auto-HSCT and 7 allo-HSCT recipients were enrolled in this study, all donors were HLA-identical siblings. Two of allo-HSCT recipients were relapsed auto-HSCT ones. There were 5 patients (5/12) in complete response (CR) status and 7 (7/12) in partial remission (PR) status before transplantation in auto-HSCT group, and 2 (2/7) in PR status and 3 (3/7) in progression disease (PD) status before transplantation in allo-HSCT group. The median follow-up for the surviving patients was 46.5 months (range, 1-100 months) for the whole series, two patients lost in auto-HSCT group. Three patients developed acute graft-versus-host disease (aGVHD) and 5 chronic graft-versus-host disease (cGVHD) after allo-HSCT. Three patients died of primary disease and 1bleeding in auto-HSCT group. One patient died of primary disease and 2 transplantation-related mortality in allo-HSCT group. The 3-year cumulative overall survival (OS) were 56% (95%CI 32%-100%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.979) . The 3-year cumulative progression-free survival (PFS) were 34% (95%CI 14%-85%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.451) .
Conclusion:Both auto-HSCT and allo-HSCT were optimal choices for AITL. In clinical practice, which HSCT was better for AITL patients should be based on comprehensive factors including sensitivity to chemotherapy, risk stratification and disease status at transplantation.
