IMPORTANCE: Hematopoietic stem cell transplant (HSCT) is an advisable option for refractory or relapsed peripheral T-cell lymphoma (R/R-PTCL), but whether allogeneic HSCT or autologous HSCT is more beneficial is unknown.
OBJECTIVE: To compare the effectiveness and safety of allogeneic HSCT vs autologous HSCT in patients with R/R-PTCL.
DATA SOURCES: A systematic search of the PubMed, Embase, the Cochrane Central Register of Controlled Trials, Wanfang, and China National Knowledge Infrastructure databases with the search items refractory or relapsed peripheral T-cell lymphoma, ASCT/autologous stem-cell transplantation, allo-HSCT/allogeneic stem-cell transplantation, therapeutic effect, and treatment was conducted for articles published from January 12, 2001, to October 1, 2020.
STUDY SELECTION: After duplicate and irrelevant publications were discarded, 329 were ineligible according to the inclusion (clinical trials or retrospective studies with >10 samples) and exclusion criteria (articles without overall survival [OS], progression-free survival [PFS], and transplantation-related mortality [TRM]). Thirty trials were included in the meta-analysis. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.
DATA EXTRACTION AND SYNTHESIS: Data on study design, individual characteristics, and outcomes were extracted. All statistics were pooled by applying a random-effects model.
MAIN OUTCOMES AND MEASURES: The prespecified main outcomes were OS, PFS, and TRM.
RESULTS: Of 6548 articles, data extracted from the 30 studies (including 880 patients who underwent allogeneic HSCT and 885 who underwent autologous HSCT) were included in this meta-analysis. In the allogeneic HSCT group, a 3-year OS of 50% (95% CI, 41%-60%) and PFS of 42% (95% CI, 35%-51%), a 5-year OS of 54% (95% CI, 47%-62%) and PFS of 48% (95% CI, 40%-56%), and a 3-year TRM of 32% (95% CI, 27%-37%) were observed. In the autologous HSCT group, a 3-year OS of 55% (95% CI, 48%-64%) and PFS of 41% (95% CI, 33%-51%), a 5-year OS of 53% (95% CI, 44%-64%) and PFS of 40% (95% CI, 24%-58%), and a 3-year TRM of 7% (95% CI, 2%-23%) were observed.
CONCLUSIONS AND RELEVANCE: In this systematic review and meta-analysis, OS and PFS were similar in the allogeneic HSCT and autologous HSCT groups; however, allogeneic HSCT was associated with specific survival benefits among patients with R/R-PTCL.
