Eligibility Criteria

Age Any Age · All Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
You have been diagnosed with medulloblastoma that has come back or is not responding to treatment, and there is enough tissue to determine which subtype of medulloblastoma you have.
You are a child or teenager between the ages of 3 and 18 years old, and your bones are still growing. Your doctor has confirmed this by checking your bone age, which is under 14 years for females and under 16 years for males. Your body surface area (BSA) must also meet the requirements stated in the study protocol.
You must be at least 18 years old or have reached a certain level of physical maturity (14 years old for females and 16 years old for males) before participating in the study.
You should have a disease that can be measured in two dimensions.
You must need a surgery for medical reasons.
