Hematopoietic stem-cell transplants (HSCT) are frequently being offered to individuals with CLL, the hope being that, as in other hematologic malignancies, they can prolong survival in or even cure some patients. This article analyzes which patients with CLL are appropriate candidates for HSCT, current transplant procedures, results with autologous and allogeneic HSCT, and future trends in transplantation in this form of leukemia.
