Allo-PBSCT as the First-line Treatment for Patients With the High-risk PTCL

This study is a single-center, single-arm, prospective phase II clinical trial that evaluates the efficacy and safety of allogeneic peripheral blood stem cell transplantation in the treatment of high-risk peripheral T-cells lymphoma patients achieved complete response (CR) or partial response (PR). Conventional conditioning regimen is adopted while the reduced-intensity conditioning regimens will be preferred. Donor hematopoietic stem cell infusion is performed on day 0. All patients will undergo bone marrow examination on day 14 and day 28 post-transplant, followed by bone marrow examinations every 30 days within the first year after transplantation, and every 60 days within the second year after transplantation. Positron emission tomography with 2-deoxy-2-\[fluorine-18\]fluoro-D-glucose integrated with computed tomography (18F-FDG PET/CT) imaging will be performed every 6 months after transplantation. If disease relapse is suspected during the follow-up period, bone marrow and relapse site examinations will be conducted at any time. The primary study endpoints are the 1-year and 2-year progression-free survival (PFS) rates post-transplant. Secondary study endpoints include the incidence of acute graft-versus-host disease (GVHD) within 180 days post-transplant, cumulative relapse rates at 1 year and 2 years post-transplant, 1-year and 2-year overall survival (OS), graft-versus-host disease-free, relapse-free survival (GRFS), non-relapse mortality (NRM), cumulative incidence of chronic GVHD, and the incidence of Cytomegalovirus （CMV）and Epstein-Barr virus（EBV）reactivation within 1 year.
