title: Transplantation in chronic lymphocytic leukemia.
abstract: Although there have been no randomized trials comparing the outcome of stem cell transplantation (SCT) with standard chemotherapy for patients with chronic lymphocytic leukemia (CLL), increasingly, both autologous and allogeneic SCT approaches are being explored in this disease. Clinical trials have demonstrated that these approaches are feasible, but current data suggest that autologous transplantation is not curative and myeloablative SCT, although offering the potential for cure, is associated with high treatment-related mortality. There is a clear demonstration of a graft-versus-leukemia effect in CLL, with encouraging results seen after SCT with reduced-intensity conditioning. Because no other treatment modalities are currently capable of improving survival in this disease, the treatment of choice for younger patients with poor-risk CLL may well be SCT, but continued enrollment of appropriate patients into well-designed clinical trials is vital to compare advances in SCT with the advances occurring in chemoimmunotherapy in CLL.
