Abstract: During the period 1970-1990, 50 patients with primary intraspinal gliomas were treated with either surgery alone or combined surgery and postoperative irradiation. Thirty-four patients had an ependymoma. In this group, 17 patients had a macroscopically total tumor resection; 14 of these patients did not receive further additional treatment. The other 17 patients underwent a partial resection or biopsy; 11 of these patients received postoperative radiation therapy. There were 13 patients with astrocytoma and none of these tumors was radically resected. Twelve patients with astrocytoma received postoperative radiation therapy. Average total dose was 49 Gy for both histological types. The 10-year survival rate in the whole group of patients with ependymomas was 91%. Patients with ependymoma treated with partial tumor resection followed by radiotherapy had a similar survival rate as patients with total resected tumors without postoperative irradiation. The local recurrence rate of ependymomas was 25%, without differences between both treatment modalities. There were 3 major complications due to surgery and no late complications related to radiotherapy. The 10-year survival rate in the group of patients with astrocytoma was 43% and tumor progression was the most important cause of death. Three patients had a spongioblastoma and were treated with radiotherapy following biopsy or partial resection. These patients are alive 6, 11 and 15 years after treatment without evidence of disease. On the basis of our retrospective data and those in the literature we would recommend postoperative radiation therapy in all the intraspinal gliomas where total tumor resection is not possible. The recommended total dose is 50 Gy in 5-6 weeks.
