ABSTRACT
OBJECTIVE: To explore the efficacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of relapsed or refractory peripheral T-cell lymphoma(PTCL). METHODS: The clinical data of 6 patients with relapsed or refractory PTCL undergoing allo-HSCT from Sep. 2014 to Sep. 2018 in the department of hematology, aerospace center hospital were retrospectively analyzed. Complications and disease-free survival after HSCT were observed. RESULTS: All the patients could well tolerate the conditioning regimen and acquired hematopoietic recon-struction. Following up till December 2018, with a median time of 11.5 months (1-51); acute GVHD developed in 2 cases and chronic GVHD developed in 5 cases, Among 6 cases one case died of viral pheumonia and the other 5 patients remained disease-free survival. The longest disease-free survival time has reached 51 months. CONCLUSION: allo-HSCT is a safe and effective method for relapsed or refractory peripheral T-cell lymphoma, which can be chosen as salvage treatment method for patients with primary resistance. Optimization of the conditioning regimen may result in better efficacy of allo-HSCT.
