Abstract
Background
Sphenoid wing meningiomas are a challenging surgical disease with relatively high perioperative morbidity. Most studies to date have focused on resection strategies as it relates to disease recurrence. Few have examined the optimal strategy as it relates to overall patient survival. We retrospectively reviewed our case series and evaluated extent of resection and perioperative stroke as it relates to all cause and disease-specific survival.
Patients/Methods
Ninety-four patients were included in the study. Demographics, clinical features, operative features and clinical course, and time to mortality evaluation were collected. Extent of resection (EOR) was defined as gross total (GTR, 100%), near total (NTR, ≥ 95%), and subtotal (STR, < 95%).
Results
The overall mean EOR was 94.5% with 70.2% of cases achieving GTR, 12.8% achieved NTR, and 17% achieved STR. Postoperative stroke only occurred with GTR or NTR (p = 0.041). Age alone was significant on Cox regression analysis for all cause mortality (p = 0.042, HR 1.054 [95% CI 1.002 – 1.109]). Postoperative stroke was associated with worse disease-specific mortality (p = 0.046, HR 23.337 [95% CI 1.052 – 517.782) with no impact from extent of resection (p = 0.258).
Conclusions
Although maximizing resection and minimizing recurrence is ideal, GTR or NTR confer a significantly higher stroke risk. Most patients do not die from their meningioma, as all cause mortality was associated only with age. However, perioperative stroke conferred decreased survival throughout follow up. This series demonstrates that an overly aggressive surgical philosophy negatively impacted disease specific survival.
