Meta-analysis on the efficacy of allogeneic hematopoietic stem cell transplantation to treat malignant lymphoma

Abstract

Abstract The goal of the study involved the comparison of clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and autologous hematopoietic stem cell transplantation (auto-HSCT) in the treatment of malignant lymphoma (ML). The effectiveness of allo-HSCT versus auto-HSCT in the treatment of ML was compared by searching EMBASE, PubMed, Web of Science, and the Cochrane Library for relevant studies. The confidence intervals (CI) and odds ratio (OR) of the article’s outcomes were described by a forest plot. Finally, 972 patients in seven articles were included. Overall survival (OS) did not differ significantly between allo-HSCT and auto-HSCT groups (OR  =  0.87, 95% CI: 0.66–1.14, P  =  0.31). Furthermore, there was no significant difference in adverse reactions (AR) between the two groups (OR  =  1.35, 95% CI: 0.81–2.24, P  =  0.25). We observed a significant difference in progression-free survival (PFS) between the two groups (OR  =  4.14, 95% CI: 2.93–5.35, P < 0.01). There was no evidence of publication bias in this meta-analysis. The incidence of OS and AR differ significantly between allo-HSCT and auto-HSCT, but the PFS was longer in ML patients who received allo-HSCT.
