Peripheral T-cell Lymphomas: Updates in Allogeneic Hematopoietic Stem Cell Transplantation

Abstract

Objective: Peripheral T-cell lymphomas (PTCLs) confer dismal prognosis and no consensus has been established on the role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) due to its rarity and heterogeneity. The purpose was to review key points of allo-HSCT for PTCLs, including indication, times of transplantation, conditioning regimen, graft versus host disease prophylaxis, and treatment of relapse. Data Sources: A comprehensive search in PubMed and Cochrane up to February 28, 2018, with the keywords “Peripheral”, “T”, “Lymphoma”, and “Transplantation” was done. Study Selection: Relevant articles including HSCT for PTCLs were carefully reviewed. Results: Promising data have been reported from advances in transplant technology and more and more PTCLs patients with poor prognosis could benefit from allo-HSCT. Conclusion: Allo-HSCT is a useful choice for patients with refractory/relapsed PTCLs or high-risk new diagnosed PTCLs.
