Clinical Study


The optimal postoperative management of pediatric intracranial ependymomas is controversial. We analyzed clinical prognostic factors for their influence on outcome in such children. Our retrospective series included 15 with supratentorial and 28 with infratentorial tumors. Twenty ependymomas were grade II, and 23 were anaplastic. Complete resection was performed in 18 patients, incomplete resection in 19, and stereotactic biopsy in 6. Radiotherapy was done in 31 patients and chemotherapy in 13. The surviving patients have been followed 8–232 months (median: 69 months). The median survival time was 30 months, and 5-year overall survival and progression-free survival rates were 53.9% and 45.9%, respectively. By tumor site: supratentorial, 56.6% and 50.9%; infratentorial, 52.3% and 42.5%. Multivariate analysis identified complete resection (5-year progression-free survival, 71.8%) and age <3 years old as significant favorable and adverse prognostic features (relative risk, 2.59; 95% CI, 1.05–6.38), respectively. Twenty-six children relapsed 1–107 months after diagnosis (median: 12 months). Relapses were local in 22 cases, and combined local and distant in three cases. Only one of 15 patients with supratentorial tumors developed isolated spinal metastasis. Failure at the primary site is the major obstacle to improve cure rates. The extent of surgical resection and age were the only statistically significant prognostic factors.
