Abstract
During a 20-year period (1964–1983), the authors managed 60 children with intracranial ependymomas. In 37 patients the tumors were located in the posterior cranial fossa, and in the remaining 23 they were supratentorial. The histological examination in 26 children revealed ependymoblastomas. The average duration of the clinical evolution was 4 months and 5 days in the supratentorial neoplasms and 3 months and 6 days in the subtentorial. Besides the intracranial hypertension, present in about 80% of the patients, specific localizing signs were seen in 70% of the children with subtentorial and in 40% of those with supratentorial tumors. Because of the growth pattern in posterior fossa ependymomas and despite the prevalence of histologically benign neoplasms, radical resection was accomplished in only 21.6% of the cases, as compared with 30.4% in supratentorial tumors. The postoperative mortality remains high: 29.7% in subtentorial tumors and 17.4% in supratentorial. The 1-year survival rate in subtentorial neoplasms was 70.3%, the 3-year survival 29.7%, and the 5-year survival 16.2%. The corresponding figures for supratentorial ependymomas were more favorable: 82.6%, 43.5%, and 26.1%, respectively. The most important factors for improving the outcome at the present time appear to be as radical a resection as possible, supplemented with postoperative radiotherapy and chemotherapy.
