Chemotherapy-related changes in central nervous system phospholipids and neurocognitive function in childhood acute lymphoblastic leukemia.

Journal Article (Academic article)

Long-term survivors of childhood leukemia are at risk for neurocognitive impairment, although the neurophysiological basis is not well understood. The purpose of this study was to explore associations between changes in cerebrospinal fluid (CSF) phospholipids and neurocognitive function in children undergoing chemotherapy for acute lymphoblastic leukemia. Seventy-six children were followed prospectively from diagnosis. CSF samples were collected during scheduled lumbar punctures and phospholipids were extracted. Neurocognitive evaluations were conducted annually beginning shortly after diagnosis. Concentrations of sphingomyelin (SM) increased following induction (p = 0.03) and consolidation (p = 0.04), while lysophosphatidylcholine (LPC) increased following induction (p = 0.003). Multivariable analyses demonstrated associations between post-induction SM and motor speed at 1 year (p
