MATERIAL and METHODS: Medical records and follow-up notes of 23 pediatric patients aged <18 years (12 male and 11 female; mean age on presentation, 13.1 ± 4.4 years) harboring 27 meningiomas operated between 1994 and 01/2019 at Hacettepe University Ihsan Dogramaci Childrenâs Hospital were evaluated.
RESULTS: One patient had neurofibromatosis (NF) type 1, and five patients had NF2. Tumors were most commonly located in the convexity (n=6) and parasagittal or falcine (n=6). Gross total resection was performed in 70.4% of cases. WHO grade I tumors accounted for 56% of all cases, whereas high-grade meningiomas accounted for 44% (33% grade II, 11% grade III). The mean follow-up duration was 10.3 ± 7.7 years. Three patients (13%) died during follow-up, and 76.2% of the patients had favorable outcome (Glasgow Outcome Scale > 3) during the last follow-up assessment. Ten patients (43.5%) had relapse. In univariate analysis, low histological grade (p=0.030) and gross total resection (p=0.024) were associated with favorable outcome. The 10-year overall survival rate was 86%.
CONCLUSION: Meningiomas in the pediatric age group are surgically treatable tumors with fairly good outcomes. However, relapses are common even for low-grade tumors; therefore, long-term surveillance and aggressive treatment are needed.
