Brain Tumors In Children And Young Adults

Girl’s rare brain tumor disappears
  • Brain tumors are the second most common malignancy among children, involving about one out of five pediatric cancer cases .
  • Brain tumors are the leading cause of solid tumor cancer death in children. They are the second leading cause of cancer death in males up to 39 years of age and the fifth leading cause of cancer death in women 20-39 years of age.
  • The most common types of pediatric tumors are medulloblastomas, low-grade astrocytomas, brain stem gliomas and ependymomas.

How Is Brain Cancer Treated

There are several treatments for brain cancer. Treatment for primary brain cancer will be different from treatment for cancers that have metastasized from other sites.

You may receive one or more treatments depending on the type, size, and location of your brain tumor. Your age and general health are also factors.

Treatments include:

What Tests Do Doctors Use To Diagnose Brain Cancer

The initial test is an interview that includes a medical history and physical examination of the person by a health care provider. The results of this interaction will determine if other specific tests need to be done.

The most frequently used test to detect brain cancer is a CT scan . This test resembles a series of X-rays and is not painful, although sometimes a dye needs to be injected into a vein for better images of some internal brain structures. Another test that is gaining popularity because of its high sensitivity for detecting anatomic changes in the brain is MRI . This test also shows the brain structures in detail better than CT. If the tests show evidence of brain cancer, then other doctors such as neurosurgeons and neurologists that specialize in treating brain ailments will be consulted to help determine what should be done to treat the patient. Occasionally, a tissue sample may be obtained by surgery or insertion of a needle to help determine the diagnosis. Other tests may be ordered by the health care practitioner to help determine the patient’s state of health or to detect other health problems. These tests help differentiate between cancerous and non-cancerous conditions in the brain that may produce similar symptoms .

Are Cns Tumors Hereditary

Most CNS tumors arent hereditary. The small percentage of CNS tumors that are hereditary are due to rare syndromes that make someone more likely to have specific cancers. Doctors can find people and families at risk for these conditions by offering genetic counseling and tests. If you are concerned that your family or medical history may increase your chances of developing cancer, talk to a genetic counselor. NCI-CONNECT offers patients with select rare CNS tumorsa personalized meeting with a genetic counselor during clinic.

  • How Do Healthcare Providers Diagnose These Tumors

    To help diagnose gangliocytoma and pineocytoma, your healthcare provider will ask about your symptoms and family health history. They will do a physical exam, including a neurologic exam to look at your:

    • Eye and mouth movement.
    • Reflexes.

    Your provider may also do the following tests:

    • Magnetic resonance imaging : This painless test that uses a large magnet, radio waves and a computer to produce very clear images of organs and structures within your body. Providers may do this test to look for tumors or evaluate tumor size and location.
    • CT scan: CT scans use a series of X-rays and a computer to create three-dimensional images of your soft tissues and bones. As with MRIs, providers may use this test to look for and evaluate tumors.
    • Blood test: Your provider may test your blood for unusual melatonin levels.
    • Spinal tap : This test involves obtaining a sample of your cerebrospinal fluid, which surrounds your brain and spine. Providers do this test to examine tumor cells.
    • Biopsy: Your provider removes tumor cells for testing to determine the type of tumor. They often use minimally invasive techniques such as endoscopy or stereotactic needle biopsy.

    Types Of Benign Brain Tumors

    Types of Malignant Brain Tumors

    Gliomas are the most prevalent type of adult brain tumor, accounting for 78 percent of malignant brain tumors. They arise from the supporting cells of the brain, called the glia. These cells are subdivided into astrocytes, ependymal cells and oligodendroglial cells . Glial tumors include the following:

    If your child is diagnosed with a brain tumor, you will learn there are many different brain tumor types and classifications based upon the tumors cell structure, composition, rate of growth, location, and other characteristics. The name and classification of the tumor may change as your doctor gains new information about your childs brain tumor or if the tumor changes over time.

    The types of brain tumors most common in children are not the same as those most common in adults. Childhood brain tumors frequently appear in different locations and behave differently than brain tumors in adults. Learn more about the specific types of brain tumors.

    When Should I See My Healthcare Provider

    Depending on your situation, your provider may schedule regular follow-up appointments to monitor your overall health. If you had surgery to remove the tumor, providers may recommend imaging tests to confirm the tumor hasnt come back or you havent developed a new tumor. You should see your provider anytime your initial tumor symptoms come back or if you’re concerned about new changes in your body.

    A note from Cleveland Clinic

    Ganglicytomas and pineocytomas are rare, slow-growing benign tumors that develop in your central nervous system and your pineal gland. While they arent cancerous, they can still cause medical conditions that may disrupt your life. Depending on the type of tumor you have, healthcare providers may use surgery or radiation therapy to treat these tumors. Once removed with surgery, these tumors rarely come back. If you have one of these benign tumors, ask your provider about treatment options, what you can expect after treatment and what you need know to live with these benign tumors.

    Key Statistics For Brain And Spinal Cord Tumors

    The American Cancer Societys estimates for brain and spinal cord tumors in the United States for 2021 include both adults and children.

    • About 24,530 malignant tumors of the brain or spinal cord will be diagnosed. These numbers would be much higher if benign tumors were also included.
    • About 18,600 people will die from brain and spinal cord tumors.

    Overall, the chance that a person will develop a malignant tumor of the brain or spinal cord in his or her lifetime is less than 1%. The risk of developing any type of brain or spinal cord tumor is slightly higher among women than among men, although the risk of developing a malignant tumor is slightly higher for men than for women. This is largely because certain types of tumors are more common in one gender or the other .

    Survival rates for brain and spinal cord tumors vary widely, depending on the type of tumor . Rates for some of the more common types of brain and spinal cord tumors are discussed in Survival Rates for Selected Adult Brain and Spinal Cord Tumors.

    What Are The Symptoms Of Oligodendrogliomas

    Signs and symptoms of oligodendrogliomas vary depending on the tumors size and location. Some people with oligodendrogliomas have no symptoms. Symptoms may appear when the tumor grows and presses on surrounding nerves.

    Symptoms of oligodendroglioma may include:

    • Seizures.
    • Weakness on one side of the body.
    • Language difficulty.

    What Causes Oligodendrogliomas

    Why this rare childhood brain cancer is so difficult to fight

    Doctors arent sure what causes oligodendrogliomas. The tumors begin in cells of the brain called oligodendrocytes. Oligodendrocytes are a type of cell called glial cells.

    Glial cells are glue-like cells that surround nerve cells and help them function. When these cells grow uncontrollably, a tumor forms. Oligodendroglioma is a type of tumor called a glioma, named for the type of cell glial cells from which it develops.

    Doctors suspect that in some cases, a chromosome abnormality may be the cause. Missing chromosomes can cause cells to grow into a tumor.

    Other Types Of Brain Tumors

    • Hemangioblastomas are slow-growing tumors, commonly located in the cerebellum. They originate from blood vessels, can be large in size and often are accompanied by a cyst. These tumors are most common in people ages 40 to 60 and are more prevalent in men than women.
    • Rhabdoid tumors are rare, highly aggressive tumors that tend to spread throughout the central nervous system. They often appear in multiple sites in the body, especially in the kidneys. They are more prevalent in young children, but also can occur in adults.

    Largest International Study Of Rare Childhood Brain Cancer Shows Early Molecular Diagnosis And Aggressive Therapy Could Improve Patient Outcomes

    Topics:All articles on Research

    Summary:

    SickKids researchers offer new insights into the features of ETMR brain tumours and outline potential guidelines for testing and treatment approaches.

    The Hospital for Sick Children researchers have published the first clinical management guidelines for patients with a rare and aggressive childhood brain tumour, based on a study of the largest cohort of patients with ETMR in the world. The study was published in The Lancet Child & Adolescent Health on September 29, 2021.

    ETMRs are an aggressive type of brain cancer found in infants and younger children, first identified as a type of tumour in 2000. The discovery of the C19MC gene as a genetic marker for ETMR by the Huang Lab at SickKids and subsequent insights that showed C19MC is a common genetic feature of several other infant brain cancers has highlighted the need for improved recognition of the disease. While ETMRs are estimated to be one of the most common brain cancers in children less than four, ETMR patients continue to be poorly studied and the disease lacks treatment guidelines.

    The findings also showed that nine per cent of ETMR patients in the study received no active treatment or treatment was stopped at first sign of tumour growth. The data, Khan says, underscores not only the need for prompt diagnosis but also more detailed genetic studies to help better determine which patients can avoid radiation therapy.

    What Happens In Dipg

    In DIPG, a tumor forms in the stem of the brain in an area called the pons. Itâs in the lower part of the brain that controls vital body functions like blood pressure, heart rate, swallowing, eyesight and eye movement, balance, and breathing.

    DIPG is a kind of glioma, or a tumor that starts in the brainâs glial cells. Theyâre also called pontine tumors or pontine gliomas.

    Outlook And Survival Rates

    Many things can affect how well someone does when they have cancer, including glioblastomas. Doctors often canât predict what someoneâs life expectancy will be if they have a glioblastoma. But they do have statistics that track how large groups of people whoâve had these conditions tend to do over time.

    For glioblastoma, the survival rates are:

    • One year: 25%
    • Two years: 8-12%
    • Five years: 5%

    These numbers canât predict what will happen to an individual, though. A personâs age, type of tumor, and overall health play a role. As treatments improve, people newly diagnosed with these aggressive brain tumors may have a better outcome.

    Brain Tumor Causes And Risk Factors

    Doctors donât know why some cells begin to form into tumor cells. It may have something to do with a personâs genes or his or her environment, or both. Some potential brain tumor causes and risk factors may include:

    • Cancers that spread from other parts of the body
    • Certain genetic conditions that predispose a person to overproduction of certain cells
    • Exposure to some forms of radiation

    How Is Glioblastoma Treated

    Medulloblastoma

    Nduom says its a difficult conversation to have with someone newly diagnosed with glioblastoma because of its difficult prognosis. His first step is to assure the patient that he is a neurosurgeon who focuses specifically on these types of tumors, and that he is part of a team who also are focused on finding better ways to treat these tumors safely. He sees his first job as getting the patient through the diagnosis period. The good news, he says, is that Winship has all the tools needed to provide the best surgical treatment of glioblastoma, and to determine the tumors level of susceptibility to radiation and chemotherapy.

    After determining the tumors molecular characterization, the conversation shifts to prognosis and treatment. Armed with all the information gathered about the tumor, the next step is an appointment with the patients team, which includes neurosurgeons, to talk about recovery neuro-oncologists, the doctors who treat brain tumors with medicine and radiation oncologists, whose role is to focus on delivering safe and effective radiation to further control these lesions.

    The most important thing that I tell them, says Nduom, is theres something we can do to help. No matter what type of tumor theyre dealing with, no matter whether theyre facing some further health challenges, theres something we can do to make them more comfortable, theres something we can do to slow down the lesion.
