Typically, children and adults with medulloblastoma receive these drugs as an injection into the vein (intravenous chemotherapy). Chemotherapy may be recommended in some cases during radiation treatment. Certain high dose chemotherapy may also be followed by stem cell rescue (a stem cell transplant using the patient's own stem cells).
Where does medulloblastoma spread?
Medulloblastoma can spread to the covering of the brain and spinal cord – that is why patients get radiation to the tumor bed (where their tumor was before surgery) as well as the rest of the brain and the entire spinal cord. The most common type of radiation is called external-beam radiation therapy.

Care and recommendations of treatment are typically recommended by a neuro-oncologist.
What is radiation treatment?
Radiation is a cancer treatment that uses high-energy X rays or other types of radiation to kill cancer cells. It was first noted in the 1950s that patients who received radiation to their brain and their spine had higher survival rates compared to patients who did not receive radiation.
Can medulloblastoma be treated with chemotherapy?
Typically, children and adults with medulloblastoma receive these drugs as an injection into the vein (intravenous chemotherapy). Chemotherapy may be recommended after surgery or radiation therapy, or in certain cases, at the same time as radiation therapy.
How to diagnose medulloblastoma?
The process of diagnosis usually starts with a medical history review and a discussion of signs and symptoms. Tests and procedures used to diagnose medulloblastoma include: 1 Neurological exam. During this procedure, vision, hearing, balance, coordination and reflexes are tested. This helps determine which part of the brain might be affected by the tumor. 2 Imaging tests. Imaging tests can help determine the location and size of the brain tumor. These tests are also very important to identify pressure or blockage of the CSF pathways. A computerized tomography (CT) scan or magnetic resonance imaging (MRI) may be done right away. These tests are often used to diagnose brain tumors. Advanced techniques, such as perfusion MRI and magnetic resonance spectroscopy, also may be used. 3 Tissue sample testing (biopsy). A biopsy is usually not done, but it may be recommended if the imaging tests are not typical of medulloblastoma. The sample of suspicious tissue is analyzed in a lab to determine the types of cells. 4 Removal of cerebrospinal fluid for testing (lumbar puncture). Also called a spinal tap, this procedure involves inserting a needle between two bones in the lower spine to draw out cerebrospinal fluid from around the spinal cord. The fluid is tested to look for tumor cells or other abnormalities. This test is only done after managing the pressure in the brain or removing the tumor.
Where does medulloblastoma start?
Medulloblastoma is a type of brain cancer that starts in the part of the brain called the cerebellum. Medulloblastoma is the most common type of cancerous brain tumor in children. Medulloblastoma (muh-dul-o-blas-TOE-muh) is a cancerous (malignant) brain tumor that starts in the lower back part of the brain, called the cerebellum.
Is medulloblastoma inherited?

Can medulloblastoma cause hydrocephalus?
A medulloblastoma may grow to block the flow of cerebrospinal fluid, which can cause a buildup of fluid that puts pressure on the brain (hydrocephalus). Surgery to create a pathway for the fluid to flow out of the brain (external ventricular drain or ventriculoperitoneal shunt) may be recommended.
What is the treatment for medulloblastoma?

Is brain tumor surgery successful?
Like all surgeries, brain tumor surgery is most successful when performed by a specialist with a great deal of experience in the particular procedure. This is especially true with brain tumors, because it is crucial to remove as much of the tumor as possible while leaving intact as much brain function as possible.
What is proton therapy?
Read more about proton therapy. Focused conformal radiation therapy, which is aimed directly at the tumor and the surrounding area. Intensity-modulated radiotherapy (IMRT), which shapes the radiation beam to the brain tumor and lessens exposure to the rest of the brain or organs.

The main types of treatment used to treat medulloblastoma include surgery, radiation therapy, and chemotherapy. Current treatment plans tailor treatment recommendations based on the molecular subgroup of medulloblastoma. Sometimes, the treatments are used in combination.
How to treat a tumor in the brain?
Because radiation therapy can sometimes interfere with the growth and development of a child’s brain and spine, the doctor may choose to treat the tumor in another way. If radiation therapy is recommended, the approach will be based on the child’s age and the features of the tumor (see Stages ): 1 For children older than 3, radiation therapy is given to the entire brain and spine, followed by radiation therapy aimed directly at the tumor and the surrounding area or the back part of the brain. 2 For children younger than 3, radiation therapy may be directed only to the back part of the brain or the tumor and the surrounding area after surgery and chemotherapy (see below).
Is brain cancer rare in children?
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. That is why more than 60% of children with cancer are treated as part of a clinical trial.
What is clinical trial?
A clinical trial is a research study that tests a new approach to treatment. The “standard of care” is the best treatments known. Clinical trials may test such approaches as a new drug, a new combination of existing treatments, or new doses of current therapies.

The cerebellum controls balance and coordinated movements. The cerebellum is found near the brainstem in a region called the posterior fossa at the back of the brain. This fast-growing tumor can spread to other areas of the brain and spinal cord through cerebrospinal fluid (CSF).
What is anaplastic medulloblastoma?
Anaplastic medulloblastoma is made up of cells with irregular shapes. Each tumor cell in large-cell medulloblastoma has a large nucleus. Medulloblastoma can also be classified by spread of disease (metastasis): M0: The tumor is in one place with no sign of spread to other parts of the body.
What is the classification of medulloblastoma?
Medulloblastoma can also be classified by spread of disease (metastasis): M0: The tumor is in one place with no sign of spread to other parts of the body. M1: Tumor cells are found in the CSF. M2: The tumor has spread to the brain. M3: The tumor has spread to the spine.

At least 75% of medulloblastomas occur in the cerebellum at the back and base of the brain. Medulloblastoma brain cancer is usually diagnosed as a grade 3 or grade 4 tumour. It is more common in boys than girls and is rarer in adults.
Is medulloblastoma a rare disease?
Because medulloblastoma is such a rare disease in adults, prognosis is very much determined on a case by case basis. Like any high-grade brain tumour, the survival rate statistics will be lower than for patients with a low-grade brain tumour, for example. The exact type of medulloblastoma makes a difference to the prognosis.
What is the most common form of medulloblastoma?
WNT-activated medulloblastoma. WNT-activated medulloblastoma is the most common form of medulloblastoma. It is named after the WNT pathway, a specific series of molecules which influence each other, and is a process that can in turn affect tumour growth. Sonic Hedgehog (SHH) activated medulloblastoma.
How are medulloblastomas classified?
Medulloblastomas are classified into four main groups using molecular and genetic analysis of biopsy tissue, and then into further subgroups using histology – variations identified on examination of tumour cells under a microscope. Tumours are thus given detailed, integrated classifications that are used to indicate a potential prognosis ...
Why is SHH important?
When messages are passed along molecules in the SHH pathway in a balanced way, it helps to control healthy embryonic development. Excessive SHH activity means that the body doesn’t stop producing this type of brain cell when it otherwise would do, so a tumour can then form from this build-up of cells.
What is the Sonic Hedgehog?
Sonic Hedgehog (SHH) activated medulloblastoma. The SHH pathway also affects tumour growth (named after the video game character “Sonic the Hedgehog” by the scientists who discovered it). When messages are passed along molecules in the SHH pathway in a balanced way, it helps to control healthy embryonic development.
Overview
