Clinical and economic comparison of allogeneic peripheral blood progenitor cell and bone marrow transplantation for acute lymphoblastic leukemia in children.
There is limited experience in the use of peripheral blood progenitor cells (PBPC) for allogeneic transplantation in children. In the present study we compared engraftment kinetics, incidence of acute and chronic graft-versus-host disease (GVHD) and the outcome and economic costs of allogeneic PBPCT vs BMT in children with ALL in a single institution. All children were transplanted in complete remission (CR) with a similar conditioning regimen and the same GVHD prophylaxis. Patients undergoing PBPCT achieved myeloid and platelet engraftment before patients undergoing BMT (P < 0.001). Platelet recovery was faster for the PBPCT group (P < 0.014 for 50 x 10(9)/l and P < 0.039 for 100 x 10(9)/l). Incidence and severity of acute and chronic GVHD were similar in both groups (acute grade 1-2: 9/13 for PBPCT vs 9/11 for BMT; chronic GVHD: 5/12 for PBPCT vs 3/8 for BMT). Hospital stay was shorter for the PBPCT than for the BMT group (28.8 days vs 42.9 days, respectively) and the PBPCT group used less clinical resources, resulting in overall lower cost for PBPCT (US $14,046) compared to BMT (US $19,840). There was no statistically significant difference in DFS between PBPCT and BMT (68.4% vs 50%, respectively).
