Postoperative management of primary spinal cord ependymomas.

Treatment and final outcome of 11 patients with primary spinal cord ependymomas admitted between 1967 and 1983 have been reviewed. All patients had undergone surgery once or twice before radiation treatment. Six of them are alive and disease-free 78 months to more than 180 months after radiation therapy. A short analysis of the recent literature is presented with special emphasis on the most frequent treatment techniques, extension of radiation fields and doses. The value of postoperative radiation therapy and the complications of both surgery and radiotherapy are analyzed. Some guidelines for treatment are finally discussed and proposed.
