Abstract
Of 488 children with central nervous system neoplasms, 43 (8.8%) had glioblastomas, 22 of which were in the cerebral hemispheres, 16 in the brain stem, two in the cerebellum, and three in the spinal cord. The male to female ratio was 3:2. Glioblastoma multiforme of the cerebral hemispheres occurred at a mean age of 12.7 years, and the frontal lobe was the most commonly involved. Main presenting symptoms included headache (85%), nausea or vomiting (65%), and seizures (35%). Papilledema (45%) was the most common physical finding. The longest survivals were achieved by a combination of operation and radiation (22 months). Brain stem glioblastomas occurred at a mean age of 6.7 years, with the pons as the most frequent site. Nausea or vomiting (50%) and headache (36%) were the main presenting symptoms; the major physical findings were ataxia (43%), cranial nerve palsies (28%), and paresis (28%). The length of survival was greatest with radiation alone (10.5 months). The period of survival of children with glioblastoma multiforme was significantly increased with steroid therapy. Glioblastoma multiforme behaves similarly in children and adults. Intracranial glioblastomas have a more rapidly fatal course than that of other similarly situated gliomas in childhood.
