Abstract
The use of allogeneic hematopoietic stem cell transplantation (HSCT) is recommended during the first complete remission of acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS). However, only 30% of these cases have fully matched sibling donors (MSDs). Alternatively, matched unrelated donors (MUDs) and haploidentical (haplo) donors from first-degree relatives increase the access to transplantation, with some reported differences in outcomes. The current systematic review and meta-analysis was conducted with the aim of summarizing the results of those studies to compare the efficacy and toxicity of MSD-HSCT and MUD-HSCT versus haplo-HSCT for patients with AML or MDS. Articles published before September 15, 2018, were individually searched for in two databases (MEDLINE and EMBASE) by two investigators. The effect estimates and 95% confidence intervals (CIs) from each eligible study were combined using the Mantel-Haenszel method. A total of 14 studies met the eligibility criteria and were included in the meta-analysis. The overall survival rates were not significantly different between the groups, with pooled odds ratios of the chance of surviving at the end of the study when comparing haplo-HSCT to MSD-HSCT and comparing haplo-HSCT to MUD-HSCT of 0.85 (95% CI: 0.70 to 1.04; I2 = 0%) and 1.12 (95% CI: 0.89 to 1.41; I2 = 33%), respectively. The pooled analyses of other outcomes also showed comparable results, except for the higher grade 2 to 4 acute graft-versus-host disease (GvHD) for patients who received haplo-HSCT than those who received MSD-HSCT, and the better GvHD-free, relapse-free survival and the lower chronic GvHD than the patients in the MUD-HSCT group. These observations suggest that haplo-HSCT is a reasonable alternative with comparable efficacy if MSD-HSCT and MUD-HSCT cannot be performed. Nonetheless, the primary studies included in this meta-analysis were observational in nature, and randomized-controlled trials are still needed to confirm the efficacy of haplo-HSCT.
