    High-dose cytosine arabinoside (ARA-C) can cause acute cerebellar toxicity in patients with refractory acute myeloid leukemia (AML). Immediate cessation of high-dose ARA-C is crucial upon observing cerebellar dysfunction.

    Area of Science:

    • Neuroscience
    • Oncology
    • Pharmacology

    Background:

    • High-dose cytosine arabinoside (ARA-C) is utilized for refractory acute myeloid leukemia (AML).
    • Cerebellar toxicity is a potential adverse effect associated with high-dose chemotherapy regimens.

    Observation:

    • A patient receiving high-dose ARA-C (3000 mg/m2/12 hours) for refractory AML presented with clinical and morphologic evidence of acute cerebellar toxicity.
    • Histopathological examination revealed damage to Purkinje cells and the dentate nucleus in the cerebellum.

    Findings:

    • The observed cerebellar toxicity was linked to the high-dose ARA-C regimen.
    • Previous studies have documented reversible cerebellar toxicity with identical high-dose ARA-C protocols.

    Implications:

    Related Experiment Videos

    • Clinical signs of cerebellar dysfunction necessitate the immediate discontinuation of high-dose ARA-C therapy.
    • This case highlights the importance of vigilant monitoring for neurological adverse events during intensive chemotherapy.
    • Understanding and managing ARA-C-induced neurotoxicity is critical for patient safety and treatment outcomes in AML management.
