Özet
Background The CD34+ stem cells are either noncryopreserved (non-CP) or cryopreserved (CP) in autologous stem-cell transplantation (ASCT). Some retrospective studies have shown that engraftment failure and engraftment rate are similar in CP cells and infusion reactions are lower in CP cells due to the absence of dimethyl sulfoxide. Objective In this study, we presented our clinical experience comparing the outcomes and safety of ASCT with CP and non-CP stem cells. Patients and methods A total of 163 patients were enrolled between January 2019 and June 2021. Duration of neutrophil/platelet engraftment, rates of infusion-related reactions, febrile neutropenia, and duration of hospitalization were compared between the CP and non-CP groups. Results Fifty five (33.7%) received CP cells, 108 (66.3%) received non-CP cells. The median dose of CD34+ cells was similar in both groups (P=0.755). The median duration of neutrophil and platelet engraftment was not statistically significantly different in CP and non-CP groups (P=0.896 and 0.183, respectively). No statistical difference was observed in the median duration of hospitalization between the two groups [CP: 16 (13-26) vs. non-CP: 15 (11-31) days, P=0.124]. The febrile neutropenia rate was higher in the CP group, but there was no statistical difference between the two groups (CP: 56.4% vs. non-CP, 48.1%, P=0.301). The rates of infusion-related reaction such as nausea, vomiting, and rash were higher in the CP group (21.8 vs. 12%), with no statistically significant difference (P=0.159). Conclusion Non-CP cells have similar outcomes to CP cells and lower toxicity than CP cells, which are safe and effective in ASCT.
