Analysis of the efficacy of autologous peripheral blood stem cell
transplantation in high-risk neuroblastoma
Abstract
Objective This study aimed to analyse the efficacy of autologous
peripheral blood stem cell transplantation for high-risk neuroblastoma
in China. Methods The data of 90 high-risk neuroblastoma patients
treated with the CCCG-NB 2015 regimen at the Tianjin Medical University
Cancer Institute & Hospital were reviewed. The baseline
clinicopathological characteristics and prognosis of were analysed and
compared. In addition, the prognoses of tandem autologous stem cell
transplantation and single autologous stem cell transplantation groups
were compared. Results The results of survival analysis showed that
autologous peripheral blood stem cell transplantation based on this
pretreatment regimen significantly improved the prognosis of children in
the high-risk group. The 3-year event-free survival (EFS) and overall
survival (OS) rates for the transplantation group and the
nontransplantation group were 65.5% vs. 41.3% (P=0.023) and 77.1% vs.
57.9% (P=0.03), respectively. There was no difference in the
distribution of baseline clinical case characteristics between the
single transplantation group and the tandem transplantation group
(P>0.05), and there was no significant difference in EFS
and OS between the two groups (P>0.05). Conclusion Based on
this pretreatment programme, autologous peripheral blood stem cell
transplantation is safe and tolerable and significantly improves the
prognosis of children in the high-risk group. The value of tandem
autologous stem cell transplantation is worthy of further discussion,
which should consider various aspects such as the transplantation plan
and the patient’s state.
