title: [Comparison of allogeneic or autologous hematopoietic stem cell transplant for high-risk peripheral T cell lymphomas].
abstract: Objective:To evaluate the efficacy of auto-HSCT and allo-HSCT in the treatment of high risk peripheral T cell lymphoma (PTCL).Methods:From July 2007 to July 2014, 60 cases of high risk PTCL were analyzed retrospectively.Results:All 60 patients were at high risk group (carried with IPI≥3), with a median age of 31 (12-58) years old. Of the 60 cases, 22 were PTCL-not otherwise specified (PTCL-NOS), 22 ALK negative anaplastic large cell lymphoma (ALK-negative ALCL) and 16 angioimmunoblastic T-cell lymphoma (AITL). Twenty-one patients (21/60) received allo-HSCT, and thirty-nine (39/60) auto-HSCT. Before receiving transplantation, 40/60 patients were in complete remission (CR), 2/60 patients partial remission (PR) and 18/60 patients not remission (NR). In the 40 CR patients before transplant, 10 patients received allo-HSCT and 30 patients auto-HSCT, respectively. In the 20 PR/NR patients before transplant, 11 patients received allo-HSCT and 9 patients auto-HSCT, respectively. After a median follow-up of 39 (range 1-96) months, the K-M analysis showed that the 5-year PFS by auto-HSCT and allo-HSCT were 61% and 60% (P=0.724) , respectively. The 5-year OS by auto-HSCT and allo-HSCT were 62% and 61% (P=0.724) , respectively. There were no statistically significant differences between auto-HSCT and allo-HSCT. And the cumulative TRM of auto-HSCT and allo-HSCT were 22.7% and 41.8% (P=0.250) , respectively within 5-years after transplantation. At the end of the last follow-up, 7 and 2 patients relapsed in auto-HSCT and allo-HSCT groups respectively, the 5-year cumulative recurrence rates of auto-HSCT and allo-HSCT transplantation were 37.2% and 10.1% (P=0.298), respectively.Conclusion:There was no significant difference in the long-term survival between auto-HSCT and allo-HSCT for high risk PTCL patients. Outcome by allo-HSCT may be better for NR patients.
