Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of non-Hodgkin's lymphoma that carries, except for ALK-positive anaplastic large cell lymphoma, a poor prognosis. Only a third of patients live 5years past diagnosis. The incidence of PTCL has been increasing during the last two decades. In recent years, there was a rising interest in PTCL manifested by the abundance of publications dedicated exclusively to this disease. The international T-cell lymphoma project was formed with an aim of unifying efforts towards a better understanding of the diagnosis and management of this disease. Given the poor outcomes of PTCL patients, high-dose chemotherapy and autologous stem-cell transplantation (HDT/ASCT) have been used in the up-front and salvage settings, with different success rates. However, there are no prospective randomized controlled trials addressing the role of HDT/ASCT in a PTCL-restricted population. This article critically reviews the data available from the retrospective and prospective studies addressing this topic. We will emphasize the favorable prognostic factors of HDT/ASCT such as a solid remission at the time of transplantation, a chemotherapy sensitive disease and a low prognostic index score. As novel agents and new therapeutic strategies are introduced, there is a continued need for prospective randomized trials to define the optimal use of HDT/ASCT in managing PTCL.
