ABSTRACT
Objective:
To explore the incidence rates, clinical features, risk factors and its impacts on survival of central nervous system complications (CNSC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:
From June 2011 to October 2018, 237 consecutive patients undergoing allo-HSCT were retrospectively analyzed.Results:
The incidence of CNSC was 10.5%(25/237) and the median time 82(-4 - 810) days post-transplantation. The most common instances of CNSC were drug-associated encephalopathy (n=6), CNS infection (n=5), unexplained convulsions (n=4), metabolic encephalopathy (n=3), immune-related encephalopathy (n=3), primary central relapse (n=3) and cerebrovasculopathy (n=1). The most common clinical symptom was epileptic seizure (n=11). CsA-related encephalopathy was manifested mainly as posterior reversible encephalopathy syndrome on brain MRI. Metabolic encephalopathy is mostly demyelination. Most hippocampal lesions were caused by immune-related encephalopathy or CNS infection. Analysis of risk factors indicated that umbilical cord blood transplantation, HLA incompatible transplantation and delayed platelet implantation were high risk factors for post-transplantation occurrence of CNSC. Survival analysis suggested that non-relapse mortality rate (42.9%, 9/21) in group with CNSC of malignant hemoblastosis was higher than that in group without CNSC (15.3%, 27/176) and inter-group difference was statistically significant ( χ2=9.511, P=0.005). The 1/3-year OS rates in group with CNSC were lower than those in group without CNSC (56.6% vs 77.8%; 37.1% vs 65.7%). And the difference was statistically significant ( P=0.022).Conclusions:
With a complex etiology, CNSC is one of serious complications after allo-HSCT and it significantly reduces the overall survival rate of patients. Umbilical cord blood transplantation, HLA incompatible transplantation and delayed platelet implantation are high-risk groups for CNSC.
