We previously compared outcomes after allogeneic peripheral-blood stem cell (PBSC) and bone marrow (BM) transplantation in 706 patients with leukemia. We obtained long-term follow up on 413 of 491 patients who were alive at the time of the initial report: 141 PBSC and 272 BM recipients. Chronic graft-versus-host disease (GVHD) was more frequent after PBSC compared to BM transplantation (RR 1.65, P < .001) yet relapse rates were similar in both groups. Leukemia-free survival rates were higher after PBSC than BM transplantation for patients with advanced chronic myeloid leukemia (33% versus 25%) but lower for those in first chronic phase (41% versus 61%) due to higher rates of late transplant-related mortality. Leukemia-free survival was similar after PBSC and BM transplantation for acute leukemia. These data represent the early experience with PBSC grafts. Long-term outcomes in recipients of more recent transplants are required to better evaluate the role of PBSC grafts relative to BM transplantation.
