Summary
This summary is machine-generated.

Surgical resection of intracranial meningiomas offers a good prognosis, with total resection achieving better long-term outcomes. Subtotal resection may require adjuvant radiation therapy to prevent tumor recurrence.

Area of Science:

  • Neurosurgery
  • Oncology

Context:

  • Intracranial meningiomas represent a significant subset of primary brain tumors.
  • Surgical management is the primary treatment modality for these tumors.

Purpose:

  • To evaluate the outcomes of surgical resection for intracranial meningiomas.
  • To assess the impact of total versus subtotal resection and adjuvant radiation therapy on recurrence rates.

Summary:

  • This study reviewed 28 patients who underwent surgical excision of intracranial meningiomas between 1974 and 1992.
  • Total resection was achieved in 57.1% of cases, with one recurrence. Subtotal resection in 12 patients led to recurrence in 3/8 treated with radiation and 3/4 not treated with radiation within 5 years.

Impact:

  • Total resection is associated with a lower risk of recurrence for accessible intracranial meningiomas.

  • Adjuvant radiation therapy following subtotal resection may reduce, but not eliminate, the risk of recurrence.
