Evaluation of radiotherapy for pediatric CNS tumors.

Despite the recent progress in neurosurgery and development of new chemotherapy drugs, radiotherapy is still an essential method of combined treatment for pediatric central nervous system tumors. The new approach of radiotherapy, such as conformal and stereotactic methods have recently been developed. These new methods and recommendations for treatment of pediatric brain tumors, such as astrocytoma, medulloblastoma, and ependymoma are presented. The side effects of treatment are also considered. In addition, the perspective of future development of radiotherapy in central nervous system tumors is presented.
