Allogeneic Hematopoietic Stem Cell Transplantation Following Conventional Chemotherapy in High Risk Peripheral T Cell Lymphoma

Results of conventional therapy in patients with peripheral T-cell lymphoma(PTCL) are poor. Allogeneic hematopoietic stem cell transplantation(allo-HSCT) gave excellent results in PTCL after failure of conventional therapy and in many cases also of HDT/ASCT. A disadvantage of allo-HSCT is high TRM rate, especially in refractory or relapsed patients. Another limitation to the use of allo-HSCT is the availability of a HLA matched donors. Haploidentical family donors have been successfully used in treatments of hematologic malignancies, including malignant lymphomas. Thus, allo-HSCT could be used as first-line consolidation following conventional chemotherapy in high-risk PTCL patients. The study hypothesis: Using allo-HSCT as consolidation following chemotherapy in high-risk PTCL exerts a strong anti-lymphoma effect and could increase response rate and improve long term survival.
