Childhood brain stem glioma is a disease in which benign (noncancer) or malignant (cancer) cells form in the tissues of the brain stem.
Gliomas are tumors formed from glial cells. Glial cells in the brain hold nerve cells in place, bring food and oxygen to them, and help protect them from disease, such as infection. The brain stem is the part of the brain connected to the spinal cord. It is in the lowest part of the brain, just above the back of the neck. The brain stem is the part of the brain that controls breathing, heart rate, and the nerves and muscles used in seeing, hearing, walking, talking, and eating. Most childhood brain stem gliomas are pontine gliomas, which form in a part of the brain stem called the pons. Brain tumors are the third most common type of cancer in children. This summary refers to the treatment of primary brain tumors (tumors that begin in the brain). Treatment for metastatic brain tumors, which are tumors formed by cancer cells that begin in other parts of the body and spread to the brain, is not discussed in this summary. Brain tumors can occur in both children and adults; however, treatment for children may be different than treatment for adults. See the following PDQ treatment summaries for more information: - Childhood Brain and Spinal Cord Tumors Treatment Overview - Adult Central Nervous System Tumors Treatment
Brain tumors may be benign (not cancer) or malignant (cancer).
Benign brain tumors grow and press on nearby areas of the brain. They rarely spread into other tissues. Malignant brain tumors are likely to grow quickly and spread into other brain tissue. When a tumor grows into or presses on an area of the brain, it may stop that part of the brain from working the way it should. Both benign and malignant brain tumors can cause signs and symptoms and need treatment.
There are two types of brain stem gliomas in children.
Childhood brain stem glioma is either a diffuse intrinsic pontine glioma (DIPG) or a focal glioma. - DIPG is a high-grade tumor that is fast-growing and spreads all through the brain stem. It is hard to treat and has a poor prognosis (chance of recovery). Children younger than 3 years diagnosed with DIPG may have a better prognosis than children who are 3 years and older. - A focal glioma is slow-growing and is in one area of the brain stem. It is easier to treat than DIPG and has a better prognosis.
Question: How to diagnose Childhood Brain Stem Glioma ?
Answer: Tests that examine the brain are used to detect (find) childhood brain stem glioma. 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 patients 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 persons 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. - 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 areas inside the brain. 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).
- A biopsy may be done to diagnose certain types of brain stem glioma. If the MRI scan looks like the tumor is a DIPG, a biopsy is usually not done and the tumor is not removed. If the MRI scan looks like a focal brain stem glioma, a biopsy may be done. A part of the skull is removed and a needle is used to remove a sample of the brain tissue. Sometimes, the needle is guided by a computer. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are found, the doctor will remove as much tumor as safely possible during the same surgery. The following test may be done on the tissue that was removed: - Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between brain stem glioma and other brain tumors.
Question: What are the stages of Childhood Brain Stem Glioma ?
Answer: Key Points
- The plan for cancer treatment depends on whether the tumor is in one area of the brain or has spread all through the brain.
The plan for cancer treatment depends on whether the tumor is in one area of the brain or has spread all through the brain.
Staging is the process used to find out how much cancer there is and if cancer has spread. It is important to know the stage in order to plan treatment. There is no standard staging system for childhood brain stem glioma. Treatment is based on the following: - Whether the tumor is newly diagnosed or recurrent (has come back after treatment). - The type of tumor (either a diffuse intrinsic pontine glioma or a focal glioma).
Question: what research (or clinical trials) is being done for Childhood Brain Stem Glioma ?
Answer: New types of treatment are being tested in clinical trials.
Information about clinical trials is available from the NCI website.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
Question: What is (are) Prostate Cancer ?
Answer: Key Points
- Prostate cancer is a disease in which malignant (cancer) cells form in the tissues of the prostate. - Prostate cancer is the most common nonskin cancer among men in the United States. - Different factors increase or decrease the risk of developing prostate cancer.
Prostate cancer is a disease in which malignant (cancer) cells form in the tissues of the prostate.
The prostate is a gland in the male reproductive system located just below the bladder (the organ that collects and empties urine) and in front of the rectum (the lower part of the intestine). It is about the size of a walnut and surrounds part of the urethra (the tube that empties urine from the bladder). The prostate gland produces fluid that makes up part of semen. As men age, the prostate may get bigger. A bigger prostate may block the flow of urine from the bladder and cause problems with sexual function. This condition is called benign prostatic hyperplasia (BPH), and although it is not cancer, surgery may be needed to correct it. The symptoms of benign prostatic hyperplasia or of other problems in the prostate may be similar to symptoms of prostate cancer. See the following PDQ summaries for more information about prostate cancer: - Prostate Cancer Prevention - Prostate Cancer Treatment
Question: What are the symptoms of Breast Cancer ?
Answer: Signs of breast cancer include a lump or change in the breast.
These and other signs may be caused by breast cancer or by other conditions. Check with your doctor if you have any of the following: - A lump or thickening in or near the breast or in the underarm area. - A change in the size or shape of the breast. - A dimple or puckering in the skin of the breast. - A nipple turned inward into the breast. - Fluid, other than breast milk, from the nipple, especially if it's bloody. - Scaly, red, or swollen skin on the breast, nipple, or areola (the dark area of skin around the nipple). - Dimples in the breast that look like the skin of an orange, called peau dorange.
It may be difficult to detect (find) breast cancer early in pregnant or nursing women.
The breasts usually get larger, tender, or lumpy in women who are pregnant, nursing, or have just given birth. This occurs because of normal hormone changes that take place during pregnancy. These changes can make small lumps difficult to detect. The breasts may also become denser. It is more difficult to detect breast cancer in women with dense breasts using mammography. Because these breast changes can delay diagnosis, breast cancer is often found at a later stage in these women.
Question: What is (are) Nasopharyngeal Cancer ?
Answer: Key Points
- Nasopharyngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the nasopharynx. - Ethnic background and being exposed to the Epstein-Barr virus can affect the risk of nasopharyngeal cancer. - Signs of nasopharyngeal cancer include trouble breathing, speaking, or hearing. - Tests that examine the nose and throat are used to detect (find) and diagnose nasopharyngeal cancer. - Certain factors affect prognosis (chance of recovery) and treatment options.
Nasopharyngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the nasopharynx.
The nasopharynx is the upper part of the pharynx (throat) behind the nose. The pharynx is a hollow tube about 5 inches long that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes from the throat to the stomach). Air and food pass through the pharynx on the way to the trachea or the esophagus. The nostrils lead into the nasopharynx. An opening on each side of the nasopharynx leads into an ear. Nasopharyngeal cancer most commonly starts in the squamous cells that line the nasopharynx. Nasopharyngeal cancer is a type of head and neck cancer.
Question: what research (or clinical trials) is being done for Nasopharyngeal Cancer ?
Answer: New types of treatment are being tested in clinical trials.

Question: What are the stages of Childhood Central Nervous System Germ Cell Tumors ?
Answer: Key Points
- Childhood central nervous system (CNS) germ cell tumors rarely spread outside of the brain and spinal cord.
Childhood central nervous system (CNS) germ cell tumors rarely spread outside of the brain and spinal cord.
Staging is the process used to find out how much cancer there is and if cancer has spread. There is no standard staging system for childhood central nervous system (CNS) germ cell tumors. The treatment plan depends on the following: - The type of germ cell tumor. - Whether the tumor has spread within the CNS or to other parts of the body. - The results of tests and procedures done to diagnose childhood CNS germ cell tumors. - Whether the tumor is newly diagnosed or has recurred (come back) after treatment.
Question: what research (or clinical trials) is being done for Childhood Central Nervous System Germ Cell Tumors ?
Answer: Check the list of NCI-supported cancer clinical trials that are now accepting patients with childhood central nervous system germ cell tumor. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your child's doctor about clinical trials that may be right for your child. General information about clinical trials is available from the NCI website.

Question: What is (are) Childhood Acute Lymphoblastic Leukemia ?
Answer: Key Points
- Childhood acute lymphoblastic leukemia (ALL) is a type of cancer in which the bone marrow makes too many immature lymphocytes (a type of white blood cell). - Leukemia may affect red blood cells, white blood cells, and platelets. - Past treatment for cancer and certain genetic conditions affect the risk of having childhood ALL. - Signs of childhood ALL include fever and bruising. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose childhood ALL. - Certain factors affect prognosis (chance of recovery) and treatment options.
Childhood acute lymphoblastic leukemia (ALL) is a type of cancer in which the bone marrow makes too many immature lymphocytes (a type of white blood cell).
Childhood acute lymphoblastic leukemia (also called ALL or acute lymphocytic leukemia) is a cancer of the blood and bone marrow. This type of cancer usually gets worse quickly if it is not treated. ALL is the most common type of cancer in children.
Leukemia may affect red blood cells, white blood cells, and platelets.
In a healthy child, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - Platelets that form blood clots to stop bleeding. - White blood cells that fight infection and disease. A lymphoid stem cell becomes a lymphoblast cell and then one of three types of lymphocytes (white blood cells): - B lymphocytes that make antibodies to help fight infection. - T lymphocytes that help B lymphocytes make the antibodies that help fight infection. - Natural killer cells that attack cancer cells and viruses. In a child with ALL, too many stem cells become lymphoblasts, B lymphocytes, or T lymphocytes. The cells do not work like normal lymphocytes and are not able to fight infection very well. These cells are cancer (leukemia) cells. Also, as the number of leukemia cells increases in the blood and bone marrow, there is less room for healthy white blood cells, red blood cells, and platelets. This may lead to infection, anemia, and easy bleeding. This summary is about acute lymphoblastic leukemia in children, adolescents, and young adults. See the following PDQ summaries for information about other types of leukemia: - Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment - Adult Acute Lymphoblastic Leukemia Treatment - Chronic Lymphocytic Leukemia Treatment - Adult Acute Myeloid Leukemia Treatment - Chronic Myelogenous Leukemia Treatment - Hairy Cell Leukemia Treatment
Question: what research (or clinical trials) is being done for Childhood Acute Lymphoblastic Leukemia ?
Answer: New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Chimeric antigen receptor (CAR) T-cell therapy CAR T-cell therapy is a type of immunotherapy that changes the patient's T cells (a type of immune system cell) so they will attack certain proteins on the surface of cancer cells. T cells are taken from the patient and special receptors are added to their surface in the laboratory. The changed cells are called chimeric antigen receptor (CAR) T cells. The CAR T cells are grown in the laboratory and given to the patient by infusion. The CAR T cells multiply in the patient's blood and attack cancer cells. CAR T-cell therapy is being studied in the treatment of childhood ALL that has relapsed (come back) a second time.

Question: Who is at risk for Childhood Acute Lymphoblastic Leukemia? ?
Answer: Key Points
Past treatment for cancer and certain genetic conditions affect the risk of having childhood ALL. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your child's doctor if you think your child may be at risk. Possible risk factors for ALL include the following: - Being exposed to x-rays before birth. - Being exposed to radiation. - Past treatment with chemotherapy. - Having certain genetic conditions, such as: - Down syndrome. - Neurofibromatosis type 1. - Bloom syndrome. - Fanconi anemia. - Ataxia-telangiectasia. - Li-Fraumeni syndrome. - Constitutional mismatch repair deficiency (mutations in certain genes that stop DNA from repairing itself, which leads to the growth of cancers at an early age). - Having certain changes in the chromosomes or genes.
Risk Groups
- In childhood ALL, risk groups are used to plan treatment. - Relapsed childhood ALL is cancer that has come back after it has been treated.
In childhood ALL, risk groups are used to plan treatment.
There are three risk groups in childhood ALL. They are described as: - Standard (low) risk: Includes children aged 1 to younger than 10 years who have a white blood cell count of less than 50,000/L at the time of diagnosis. - High risk: Includes children 10 years and older and/or children who have a white blood cell count of 50,000/L or more at the time of diagnosis. - Very high risk: Includes children younger than age 1, children with certain changes in the genes, children who have a slow response to initial treatment, and children who have signs of leukemia after the first 4 weeks of treatment. Other factors that affect the risk group include the following: - Whether the leukemia cells began from B lymphocytes or T lymphocytes. - Whether there are certain changes in the chromosomes or genes of the lymphocytes. - How quickly and how low the leukemia cell count drops after initial treatment. - Whether leukemia cells are found in the cerebrospinal fluid at the time of diagnosis. It is important to know the risk group in order to plan treatment. Children with high-risk or very highrisk ALL usually receive more anticancer drugs and/or higher doses of anticancer drugs than children with standard-risk ALL.
Relapsed childhood ALL is cancer that has come back after it has been treated.
The leukemia may come back in the blood and bone marrow, brain, spinal cord, testicles, or other parts of the body. Refractory childhood ALL is cancer that does not respond to treatment.
