Fluorouracil can cause acute neurological side effects like confusion, seizures, and cerebellar syndrome. While often dose-related and self-limiting, clinicians must consider this neurotoxicity in patients presenting with neurological symptoms.

Area of Science:

  • Neuroscience
  • Oncology
  • Pharmacology

Background:

  • Fluorouracil (5-FU) is a widely used chemotherapeutic agent.
  • Neurotoxicity is a known, though less common, adverse effect of 5-FU.
  • Understanding the spectrum of 5-FU neurotoxicity is crucial for patient management.

Observation:

  • A case of acute neurotoxicity following 5-FU treatment for esophageal carcinoma is presented.
  • The patient experienced confusion, cognitive disturbances, cerebellar syndrome, and seizures.
  • Brain imaging and CSF analysis were unremarkable, with symptoms resolving partially after treatment.

Findings:

  • Fluorouracil can induce both acute and delayed neurotoxicity.
  • Acute neurotoxicity may present as encephalopathy, cerebellar syndrome, or rarely, seizures.

  • Delayed neurotoxicity, particularly with combination therapy, can manifest as leukoencephalopathy.

    • Implications:

    • Clinicians should maintain a high index of suspicion for 5-FU neurotoxicity.
    • Prompt recognition and management can mitigate severe neurological outcomes.
    • Awareness of dose-related and immune-mediated neurotoxic mechanisms guides treatment strategies.
