Medulloblastoma, other CNS embryonal tumors, and pineoblastoma in children are treated based on the tumor type and the child's age.

Cancer stage describes the extent of cancer in the body, such as the size of the tumor, whether it has spread, and how far it has spread from where it first formed. There is no staging system used for childhood medulloblastoma, other central nervous system (CNS) embryonal tumors, or pineoblastoma, but the tests and procedures done to diagnose the cancer are also used to help plan treatment.

Treatment of other CNS embryonal tumors and pineoblastoma in children is based on the child's age. Children aged 3 years and younger may be given different treatment than children older than 3 years.
