title: [Chromosome anomalies in brain tumors].
abstract: The authors review the literature concerning chromosomal abnormalities in childhood brain tumors: medulloblastomas, ependymomas, and gliomas of low and high grade. Though these technics require further development, they highlight the role of cytogenetic modification in oncogenesis of brain tumors.
