Stem cell transplant for Waldenstr?m macroglobulinemia: An underutilized technique

摘要

Waldenstr?m macroglobulinemia is a highly chemosensitive lymphoplasmacytic lymphoma with response rates of 90% to first-line chemotherapy. The fraction of patients undergoing stem cell transplant for this disorder appears to be lower than that of patients with multiple myeloma. The indolent nature and favorable genetic profile should make Waldenstr?m an ideal disorder for autologous stem cell transplant, with high response rates that are durable. We review the literature on autologous and allogeneic transplants for Waldenstr?m macroglobulinemia and conclude that autologous transplant is effective and underutilized in the management of this disorder. Allogeneic transplant should be considered investigational and used only in the context of a clinical trial or when other chemotherapeutic options have been exhausted.
