Objective To systematically review the efficacy and safety of non-myeloablative stem cell transplantation (NST) for the treatment of multiple myeloma (MM) after first autologous stem cell transplantation. Methods Such databases as The Cochrane Library (Issue 5, 2013), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were electronically searched to collect studies investigated the efficacy and safety of NST and non-NST for the treatment of MM after first autologous stem cell transplantation from the date of their establishment to June 13th 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed using RevMan 5.1 software. Results Seven studies involving 1 961 participants were included, of which 626 cases were in the NST group and 1 335 cases were in the non-NST group. The results of meta-analysis showed that no significant difference was found between both groups in the overall survival rate (HR=1.06, 95%CI 0.78 to 1.44, P=0.69) and progress-free survival rate (HR=0.92, 95%CI 0.76 to 1.11, P=0.39). However, there were significant differences in the complete remission rate (RR=1.29, 95%CI 1.13 to 1.48, P=0.000 2) and treatment-related mortality rate (RR=3.40, 95%CI 2.27 to 5.07, P < 0.000 01). Conclusion The efficacy of NST is not superior to non-NST for patients with MM which has received first autologous stem cell transplantation. It is not sufficient to recommend NST as the first-line treatment of MM based on the currently available evidence.
