Learn about this tumor that forms from ependymal cells in the brain and spinal cord. Treatments include surgery and radiation therapy.
Ependymoma is a type of tumor that can form in the brain or spinal cord. Ependymoma begins in the ependymal cells in the brain and spinal cord that line the passageways where the fluid (cerebrospinal fluid) that nourishes your brain flows.
Ependymoma can occur at any age, but most often occurs in young children. Children with ependymoma may experience headaches and seizures. Ependymoma that occurs in adults is more likely to form in the spinal cord and may cause weakness in the part of the body controlled by the nerves that are affected by the tumor.
Surgery is the primary treatment for ependymoma. For more aggressive tumors or for tumors that can't be removed completely with surgery, additional treatments, such as radiation therapy or chemotherapy, may be recommended.
Tests and procedures used to diagnose ependymoma include:
Based on your child's test results, the doctor may suspect ependymoma and recommend surgery to remove the tumor. Once removed, the tumor cells will be tested in a laboratory to confirm the diagnosis. Specialized tests are used to determine the types of cells and their level of aggressiveness, which the doctor may use to guide treatment decisions.
Ependymoma treatment options include:
Surgery to remove the ependymoma. Brain surgeons (neurosurgeons) work to remove as much of the ependymoma as possible. The goal is to remove the entire tumor, but sometimes the ependymoma is located near sensitive brain or spinal tissue that makes that too risky.
If the entire tumor is removed during surgery, your child may not require any additional treatment. If some tumor remains, the neurosurgeon may recommend another operation to try to remove the rest of the tumor. Additional treatments, such as radiation therapy, may be recommended for more aggressive tumors or if all of the tumor can't be removed.
Radiation therapy. Radiation therapy uses high-energy beams, such as X-rays or protons, to kill cancer cells. During radiation therapy, your child lies on a table while a machine moves around him or her, directing beams to precise points in the brain.
Radiation therapy may be recommended after surgery to help prevent more aggressive tumors from recurring or if neurosurgeons weren't able to remove the tumor completely.
Specialized techniques can help to ensure that treatment delivers radiation to the tumor cells and spares as much of the surrounding healthy tissue as possible. Conformal radiation therapy, intensity-modulated radiation therapy and proton therapy are types of radiation therapy that allow doctors to carefully and precisely deliver radiation.
