Pediatric supratentorial high-grade gliomas.

The purpose of this review is to highlight some of the pertinent concepts and controversies surrounding the diagnosis and treatment of pediatric supratentorial high-grade gliomas. Unlike the adult counterparts, pediatric high-grade gliomas are likely derived from distinct cytogenetic and molecular alterations. Surgery has been shown to play a role in extending patient survival. Some success is associated with the provision of chemotherapy. Radiotherapy remains an important adjunct in children older than age 3 years. The challenges involved in improving the poor prognosis of children in whom these very aggressive tumors have been diagnosed will be discussed, as well as some of the novel approaches being investigated to improve patient survival and quality of life.
