摘要
The effects of haploidentical rhG-CSF-mobilized blood and marrow transplantation(HBMT) on hematological malignances are well established. Previous prospective single-center studies have demonstrated better survival after HBMT versus haploidentical rhG-CSF-mobilized peripheral blood stem cell transplantation(HPBSCT) for acute leukemia(AL) not in remission(NR) or in more than the second complete remission(>CR2). To test the hypothesis that HBMT is still superior to HPBSCT for patients with AL, multiple myeloma(MM), or non-Hodgkin lymphoma(NHL) in CR1/CR2 and for patients with chronic myeloid leukemia in the first and second chronic phase lacking a matched donor, we designed a propensity score method-based multicenter study.Hematopoietic recovery, acute graft-versus-host disease(aGVHD), and chronic GVHD were comparable between the HBMT group(n=168) and the HPBSCT group(n=42). No significant differences were found in non-relapse mortality rate(20.17%±3.58%and 27.24%±7.16%, P=0.18) or relapse rate(19.96%±3.72% and 28.49%±8.25%, P=0.32) between the HBMT group and the HPBSCT group. HBMT recipients had better overall survival(65.0%±4.2% and 54.2%±8.3%, P=0.037) and disease-free survival(59.9%±4.6% and 44.3%±8.7%, P=0.051). Multivariate analysis showed that HPBSCT was associated with poorer DFS(HR(95%CI), 1.639(0.995–2.699), P=0.052). Our comparisons showed that HBMT was superior to HPBSCT as a post-remission treatment for patients lacking an identical donor.
