Efficacy of autologous versus allogeneic peripheral blood hematopoietic stem cell transplantation in non-high-risk acute myeloid leukemia patients in first complete remission
To compare the efficacy of autologous and allogeneic peripheral blood hematopoietic stem cell transplantation (PB-HCT) for non-high-risk acute myeloid leukemia (AML) patients having achieved first complete remission (CR1).
Methods
2
A total of 73 patients with CR1 stage AML (non-high risk) who underwent PB-HCT in our department from January 2012 to June 2019 were enrolled in this study
and they were 49 patients receiving allogeneic PB-HCT and 24 getting autologous PB-HCT. The time of hematopoietic reconstruction
required transfusion volume
the number times of early infections
1-year cumulative relapse incidence (RI) and non-relapse mortality (NRM)
1-year overall survival (OS) and leukemia-free survival (LFS) were compared between the 2 groups.
Results
2
There were no significant differences in hematopoietic reconstruction time
required transfusion volume and the number times of early infections between the 2 groups. As for the autol
ogous PB-HCT group and allogeneic PB-HCT group
1-year RI was 25.4% and 6.2% (
P
<
0.01); 1-year NRM was 0.0% and 8.3% (
P
=0.15); 1-year OS was 95.8% and 89.5% (
P
=0.80); and 1-year LFS was 74.6% and 85.6% (
P
=0.07)
respectively. Among the low-risk patients
there were no obvious differences in RI
NRM
LFS
and OS between the 2 groups. For the intermediate-risk patients
1-year NRM and OS were not significantly different
1-year RI was 31.6% and 8.8% (
P
<
0.01)
and 1-year LFS was 68.4% and 85.3% (
P
=0.02)
respectively. Furthermore
the intermediate-risk patients who received MSD (HLA-matched sibling donor) PB-HCT had higher LFS than the autologous group (90.5%
vs
68.4%
P
<
0.01)
while the LFS of the patients undergoing haploid-identical PB-HCT was not statistically different from autologous PB-HCT.
Conclusion
2
Autologous and allogeneic PB-HCT can result in a similar effect in the low-risk AML patients at the CR1 stage. Moreover
allogeneic PB-HCT is more effective for intermediate-risk patients
but only for the patients undergoing MSD PB-HCT. If there is a lack of HLA-matched sibling donor
autologous PB-HCT is an effective alternative.
