Abstract
Many Chinese patients with hematologic diseases, who need allogeneic hematopoietic stem cell transplantation (HSCT), lack a human leukocyte antigen-matched donor. To save these patients and to avoid collecting donor bone marrow graft, we adopted haploidentical peripheral blood HSCT with granulocyte colony stimulating factor (G-CSF) mobilized peripheral blood stem cells as the grafts without ex vivo T cell depletion. Thirty-eight patients were enrolled, and they received myeloablative preconditioning. Thirty-five patients attained a successful neutrophil and platelet recovery. The median time for the neutrophil recovery was 16 days (range of 10–23 days), and the median time for the platelet recovery was 19 days (range of 10–66 days). During the follow-up at a median time of 33.1 weeks (range of 1.1–412.6 weeks), eleven (28.9 %) patients developed aGVHD grade I–II and seven (18.4 %) patients developed aGVHD grade III–IV. The incidence of cGVHD was 27.6 %, and nine (23.7 %) patients died within the first 100 days after transplantation. The cumulative survival proportions at 1 and 2 years were 52.51 ± 8.57 % and 43.76 ± 9.11 %, respectively. These results suggested that the G-CSF-primed peripheral blood stem cell grafts, without in vitro T cell depletion, could be an appropriate stem cell source for Haplo-HSCT.
