Summary
Glioblastoma multiforme typically fails within the skull after treatment. However, consider early extradural failure in patients with high p53/Ki67 and unrepaired dura after craniotomy.
Area of Science:
- Neuro-oncology
- Surgical oncology
Background:
- Glioblastoma multiforme (GBM) commonly recurs intracranially after standard treatments.
- Extracranial and metastatic disease progression are infrequent occurrences in GBM patients.
Observation:
- Subtle extracranial findings are generally not predictive of treatment failure at the cranial convexity.
- Specific patient factors may indicate a higher risk of disease recurrence outside the dura mater.
Findings:
- High p53 and Ki67 immunoreactivity are associated with increased risk.
- Failure to close the dura during craniotomy is a critical factor in extradural recurrence.
Implications:
- Early extradural failure should be considered in select GBM patients.
- This highlights the importance of dural closure and monitoring high-risk individuals for recurrence beyond the intracranial space.
