Spinal cord ependymomas are relatively rare tumours and their management is not well established. This retrospective analysis was performed to examine the outcome of patients treated for this malignancy at our institution between 1982 and 2004.
Hospital charts of 14 consecutive patients (10 men and four women) aged 8 to 58 years (median 32 years) were retrospectively analysed. This series included nine extramedullary and five intramedullary well differentiated (eight – G1, six – G2) ependymomas. All patients were treated with primary surgery. Postoperative radiotherapy was administered in 12 patients after subtotal excision. Total dose ranged from 35Gy in 17 fractions to 50.4Gy in 28 fractions. One patient experienced spinal axis failure despite complete resection of the primary tumour and was managed with salvage radiotherapy and chemotherapy following surgical excision of the relapse. There have been no radiotherapy-related serious side effects.
One patient was lost to follow-up. Of the remaining 13 patients, at a median follow-up of 5.5 years (3 months to 20 years), 12 were alive including 11 without progression.
Conclusion: In our group of patients radiotherapy following subtotal resection or used as a single modality was well tolerated and resulted in 92% long-term survival.
