title: Intramedullary spinal cord ependymomas in children: treatment, results and follow-up.
abstract: A retrospective review of 20 pediatric patients with intramedullary spinal cord ependymomas, all of whom underwent operative resection between 1985 and 1996, was undertaken to determine surgical results, long-term follow-up and tumor recurrence. Twelve children operated on in the same period with filum or cauda equina ependymomas were not included in this study. Nine children had had previous treatment before referral. Gross total resection was achieved in 14 patients and subtotal in 6. None of these had a post-operative radiation therapy. The median follow-up period was 67 months (range 25-177 months). All children were clinically evaluated before and after operation and at the last follow-up. The clinical grade at the last follow-up showed improvement in 8 patients (40%), was unchanged in 10 (50%) and deteriorated in 2 (10%). Three patients had a recurrence, 2 at the primary site (2 and 3 years after our surgery) and 1 at a distant site (3 years after). The actuarial 5- and 10-year survival rates were both 90%; 5- and 10-year progression-free survival rates were 93 and 70%, respectively. We conclude that a complete removal can be achieved in almost all cases of intramedullary spinal cord ependymomas in children, and that the long survival rates justify avoiding post-operative radiation therapy.
