摘要
Peripheral blood stem cells have emerged as an alternative to bone marrow for allogeneic transplantation. To elucidate the advantages and disadvantages of research evidence related to the effects of allogeneic peripheral blood stem cells transplantation (PBSCT) and bone marrow transplantation (BMT) for hematological malignancies, we conducted a systematic review of the literature of randomized controlled trials comparing PBSCT to BMT. We systematically searched Cochrane Library, MEDLINE, EMBASE and CNKI up to May 2011. Two reviewers independently identified the eligible studies and assessed the methodological quality of included trials. The relevant data were extracted and analysed using RevMan 5.1. Ten trials totaling 1224 patients have been assessed. Pooled comparisons of studies of PBSCT and BMT found that the overall survival in PBSCT group was non-significantly different from that in BMT group [RR 0.92, 95% CI (0.80-1.07)]. The disease-free survival and relapse rate in PBSCT group were significantly different from that in BMT group [RR 0.67, 95% CI (0.52-0.86) and RR 0.51, 95% CI (0.34-0.76), respectively]. The number of days to reach the absolute neutrophil and platelet count were shorter with PBSCT. The rates of acute and chronic graft-versus-host disease (GVHD) in PBSCT group were significantly higher than that in the BMT group. The mortality in PBSCT group was non-significantly different from that in BMT group. We concluded that PBSCT was associated with a similar overall survival and mortality, improved disease-free survival and a decrease in relapse, faster engraftment, more GVHD when compared with BMT in transplantation for hematologic malignancies.
