Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The various types of medulloblastoma include:

ON THIS PAGE: You will learn about the different treatments doctors use for children with medulloblastoma. Use the menu to see other pages. In general, brain tumors in children are uncommon. This means it can be hard for doctors to plan treatment unless they know what has been most effective in other children.

About one-third of medulloblastoma cases in the United States occur in adults between the ages of 20 to 44. The survival rate tells you what percent of children live after the tumor is found. Percent means how many out of 100. Seventeen medulloblastoma patients (11 female, 6 male) with a median age of 23 years (range, 18-47 years) were treated with surgery, craniospinal radiation (CSRT) plus local boost, and 1 of 2 adjuvant chemotherapy regimens. All tumors were infratentorial (10 in 4th ventricle and 7 in left or right hemisphere). The clinical trials on this list are for childhood medulloblastoma treatment. All trials on the list are supported by NCI. NCI’s basic information about clinical trials explains the types and phases of trials and how they are carried out.
