The role of hematopoietic stem cell transplantation in non-Hodgkin lymphoma.

Hematopoietic stem cell transplantation has become an increasingly important treatment modality for hematologic malignancies. Autologous stem cell transplantation has become the standard of care in relapsed high-risk diffuse large B-cell lymphoma (DLBCL) patients who respond to reinduction therapy. The exact role of allogeneic transplantation in DLBCL is still unknown and it appears to be useful in only a select group of patients. The exact role of hematopoietic stem cell transplant in follicular lymphoma is evolving. The treatment of mantle cell lymphoma is challenging and stem cell transplantation may play an important role, as our understanding of the biology and natural history of this disease improves. This review focuses on studies evaluating the role of stem cell transplantation in non-Hodgkin lymphoma.
