Abstract

Adverse neurologic complications (NC) occur commonly in pediatric patients with hematologic malignancies both pre- and post-allogeneic hematopoietic cell transplant (HCT). Given this known risk, we previously obtained pre-HCT brain magnetic resonance imaging (MRI) to document baseline abnormalities but utility of this and findings are not well described. This study aimed to ( a) determine the prevalence and risk factors for abnormal brain MRI and ( b) determine prevalence and risk factors for development of new NC during and 2 years post-HCT. Retrospective chart review included 102 patients with hematologic malignancies who underwent allogeneic HCT between 2000 and 2009 at University of California San Francisco (UCSF) Children's Hospital and included standard HCT data, brain MRI reports, and NC and symptoms pre- and post-HCT. Forty-three percent of patients had abnormal findings on pre-MRI, most commonly nonspecific white matter changes. Neurologic symptoms pre-HCT was the only significant risk factor for abnormal MRI. Eleven patients (11%) developed post-HCT NC. Non-Caucasian race was the only significant risk factor for new NC. Although abnormal pre-HCT brain MRI is common, these findings are not predictive of subsequent NC post-HCT. Therefore routine surveillance may not be informative for that purpose, particularly when general anesthesia is required, which can have detrimental neurocognitive effects. Etiology of NC in pediatric HCT is likely multifactorial and may include genetic and ethnic predispositions.
