Summary
Meningioma recurrence and progression occurred twice as often in males. Angioblastic meningioma showed higher recurrence rates, with progression typically within two years post-operation.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Meningiomas are primary tumors of the central nervous system.
- Understanding recurrence and progression patterns is crucial for patient management.
Purpose of the Study:
- To analyze recurrence and progression rates in operated meningiomas.
- To identify factors associated with meningioma recurrence and progression.
Main Methods:
- Retrospective review of 123 meningioma cases operated between 1975 and 1984.
- Analysis of tumor recurrence, progression, patient demographics, and tumor characteristics.
Main Results:
- 13 cases of symptomatic tumor recurrence and 15 cases of tumor progression were identified.
- Recurrence and progression were observed twice as often in males.
- Angioblastic meningioma showed a higher recurrence rate.
- Tumor progression predominantly occurred within two years post-operation, while recurrence was evenly distributed over time.
Conclusions:
- Male gender is a risk factor for meningioma recurrence and progression.
- Angioblastic subtype is associated with increased recurrence risk.
- Timely monitoring is essential, especially within the first two years for progression.
