Childhood Brain and Spinal Cord Tumors Treatment Overview (PDQ®): Treatment - Patient Information [NCI] - General Information About Childhood Brain and Spinal Cord Tumors
This summary describes the treatment of primary brain and spinal cord tumors (tumors that begin in the brain and spinal cord). Treatment of metastatic brain and spinal cord tumors is not covered in this summary. Metastatic tumors are formed by cancer cells that begin in other parts of the body and spread to the brain or spinal cord.
The cause of most childhood brain and spinal cord tumors is unknown.
The symptoms of childhood brain and spinal cord tumors are not the same in every child.
Headaches and other symptoms may be caused by childhood brain and spinal cord tumors. Other conditions may cause the same symptoms. Check with a doctor if your child has any of the following problems:
Brain Tumor Symptoms
- Morning headache or headache that goes away after vomiting.
- Frequent nausea and vomiting.
- Vision, hearing, and speech problems.
- Loss of balance and trouble walking.
- Unusual sleepiness or change in activity level.
- Unusual changes in personality or behavior.
- Increase in the head size (in infants).
Spinal Cord Tumor Symptoms
- Back pain or pain that spreads from the back towards the arms or legs.
- A change in bowel habits or trouble urinating.
- Weakness in the legs.
- Trouble walking.
In addition to these symptoms of brain and spinal cord tumors, some children are unable to reach certain growth and development milestones such as sitting up, walking, and talking in sentences.
Tests that examine the brain and spinal cord are used to detect (find) childhood brain and spinal cord tumors.
The following tests and procedures may be used:
- Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
- Neurological exam: A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a person's mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam.
- Serum tumor marker test: A procedure in which a sample of blood is examined to measure the amounts of certain substances released into the blood by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the blood. These are called tumor markers.
- MRI (magnetic resonance imaging) with gadolinium: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of the brain and spinal cord. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- Angiogram: A procedure to look at blood vessels and the flow of blood in the brain. A contrast dye is injected into the blood vessel. As the contrast dye moves through the blood vessel, x-rays are taken to see if there are any blockages.
- PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
