How Does Imitrex Treat Headaches


Imitrex is used for migraine headaches, not for headaches due to brain tumors. Headache management can be very challenging. Headaches are a small portion of the difficulties encountered in treating brain tumors. Obviously, the more concerning portion of the treatment is focused on preserving neurologic function.

Brain Tumors In All Pediatric Populations

  • Approximately 6% of all brain tumors occur in the pediatric population
  • Approximately 1.8% of all brain tumors occur in the adolescent population of pediatric brain tumor patients
  • An estimated 4,630 new cases of pediatric brain tumors will be diagnosed in the U.S. in 2021
  • Brain tumors are the most common solid cancer in persons age 0-19 years in the U.S.
  • The five-year relative survival rate for all primary pediatric brain tumors is 76.7%
  • The rate is 64.7% for malignant tumors and 95.4% for non-malignant tumors
  • Pediatric brain tumors are the leading cause of cancer-related death among children and adolescents ages 0-19 years
  • The most prevalent brain tumor types in all pediatric patients are:
  • Pilocytic astrocytoma
  • Embryonal tumors
  • The most prevalent brain tumor types in adolescents are tumors of the pituitary
  • Overall, for all primary pediatric brain tumors, incidence rates are higher in females compared to males, and white people compared to other races/ethnicity
  • What Are The Different Types Of Brain Tumors

    The different types of brain tumors include the following:

  • Primitive neuroectodermal tumors . PNET can occur anywhere in the brain of a child, although the most common place is in the back of the brain near the cerebellum. When they occur here, they are called medulloblastomas. The symptoms depend on their location in the brain, but typically the child experiences increased intracranial pressure. These tumors are fast growing and often malignant, with occasional spreading throughout the brain or spinal cord.

  • Medulloblastomas. Medulloblastomas are one type of PNET that are found near the midline of the cerebellum. This tumor is rapidly growing and often blocks drainage of the CSF , causing symptoms associated with increased ICP. Medulloblastoma cells can spread to other areas of the central nervous system, especially around the spinal cord. A combination of surgery, radiation, and chemotherapy is usually needed to control these tumors.

  • Craniopharyngiomas. Craniopharyngiomas are benign tumors that occur at the base of the brain near the nerves from the eyes to the brain, and the hormone centers. Most occur in children and young adults, but can develop at any age. Symptoms include headaches, as well as problems with vision. Hormonal imbalances are common, including poor growth and short stature. Symptoms of increased intracranial pressure may also be seen. Although these tumors are benign, they are hard to remove due to the sensitive brain structures that surround them.

    What Are The Chances Of Surviving Brain Cancer

    That is a very challenging question to answer. By looking at a group of people with a particular brain cancer, researchers can calculate the five-year survival rate the percentage of people alive after five years. These rates vary depending on the type of malignant brain tumor. But no one can provide an accurate answer for an individual, since there are so many other factors involved. We dont view the people we help as statistics, and we take a hopeful and upbeat approach. For aggressive cancers, we look to help you survive so you can try new treatments as they become available.

    When 20-year-old Danielle Gillespie discovered she had Glioblastoma, she and her doctors were surprised. Even more surprising? Just six weeks earlier, 28-year-old Sasha Archer had come to Henry Ford with a glioblastoma too. Now, they celebrate 10 years of survivorship!

    Chemotherapy For Metastatic Brain Tumors

    Brain Tumor Stages

    Because traditional chemotherapy cannot cross the blood-brain barrier, newer treatments called targeted therapy are used as the primary type of chemotherapy for treating metastatic brain tumors.

    These drugs identify and attack cancer cells with minimal harm to normal cells while preventing the growth and spread of cancer cells. Targeted therapy can be administered after surgery or in conjunction with radiation therapy to destroy remaining cancer cells.

    Targeted therapies used to treat metastatic brain tumors include:

    • Trastuzumab for breast cancer that has spread to the brain
    • Erlotinib for the most common type of lung cancer that has spread to the brain

    How Do Clinical Trials Work For Brain Tumors

    Clinical trials for brain tumors evaluate ways to improve quality of life and assess new therapies, including immunotherapies that harness the bodys own immune system. Clinical trials also evaluate new combinations of treatments and can provide hope for those with more aggressive tumors or cancer that has returned.

    New treatments only proceed to clinical trials if they show promise and an expectation of safety. While we evaluate everyone we see for potential participation in a brain cancer clinical trial, we never want you to feel like a test subject. Our clinical trials team spends the time to answer all your questions, including those covering potential risks and benefits.

    Benign Vs Malignant Brain Tumors

    Benign brain tumors arenât aggressive and normally donât spread to surrounding tissues, although they can be serious and even life-threatening. Benign brain tumors usually have clearly defined borders and usually arenât deeply rooted in brain tissue. This makes them easier to surgically remove if theyâre in an area of the brain where itâs safe to operate. But they can come back. Benign tumors are less likely to come back than cancerous ones.

    Even a benign brain tumor can be a serious health problem. Brain tumors can damage the cells around them by causing inflammation and putting increased pressure on nearby tissue, as well as inside your skull.

    Malignant primary brain tumors are cancers that start in your brain, typically grow faster than benign tumors, and quickly invade surrounding tissue. Although brain cancer rarely spreads to other organs, it can spread to other parts of your brain and central nervous system.

    Secondary brain tumors are cancer. They come from cancer that started somewhere else in your body and spread, or metastasized, to your brain. About 1 in 4 people with cancer develop a secondary brain tumor.

    Recovery And After Effects

    After treatment, you might have some lasting problems, such as:

    • seizures
    • walking difficulties
    • speech problems

    You may need treatment and support like occupational therapy and physiotherapy to help you recover or adapt to any problems.

    It’s important to follow a healthy lifestyle to lower your risk of stroke.

    This means stopping smoking if you smoke, following a healthy diet and doing regular exercise.

    You may be able to gradually return to your normal activities as you recover, although some things may need to be avoided for life.

    What Causes Brain Tumors And Am I At Risk

    Inoperable Brain Tumors | Fast Tracking Treatments

    According to the American Cancer Society, there will be more than 79,000 new cases of primary brain tumors diagnosed each year with about one-third of those being cancerous. The average age of diagnosis is 59 years old but they most commonly occur in children and older adults. Brain tumors occur more frequently in men than in women.

    Exposure to ionizing radiation, both therapeutic and from atomic bomb exposure, has been linked to the development of certain types of primary brain tumors, including meningiomas, gliomas, and sarcomas, particularly if the exposure took place in childhood. Higher radiation doses are generally felt to increase the risk of eventually developing a brain tumor. Radiation-induced brain tumors can take anywhere from 10-30 years to form.

    With the recent popularity of cellular phones, many people have worried that their use may be a risk factor for developing brain tumors. However, there has been no conclusive evidence that cell phones increase the risk of brain tumors. There has also been concern regarding exposure to powerful magnetic fields and some sugar substitutes . Again, there has not been any conclusive evidence linking these factors to increased risk of brain cancer.

    What Treatments Are Available

    Treatment options vary depending on the type, grade, size and location of the tumor whether it has spread and your age and general health. The goal of treatment may be curative or focus on relieving symptoms . Treatments are often used in combination with one another. The goal is to remove all or as much of the tumor as possible through surgery to minimize the chance of recurrence. Radiation therapy and chemotherapy are used to treat tumors that cannot be removed by surgery alone. For example, surgery may remove the bulk of the tumor and a small amount of residual tumor near a critical structure can later be treated with radiation.


    Sometimes the best treatment is observation. For example, benign, slow growing tumors that are small and have few symptoms may be observed with routine MRI scans every year until their growth or symptoms necessitate surgery. Observation may be the best option for people who are older or with other health conditions.


    Medications are used to control some of the common side effects of brain tumors.


    Image-guided surgery technologies, tumor fluorescence, intraoperative MRI/CT, and functional brain mapping have improved the surgeonâs ability to precisely locate the tumor, define the tumorâs borders, avoid injury to vital brain areas, and confirm the amount of tumor removal while in the operating room.

    Clinical Trials For New Treatments

    Researchers are always finding new ways to treat metastatic brain tumors. These new methods are tested in clinical trials. Talk with your health care provider to find out if there are any clinical trials you should consider.

    Johns Hopkins Comprehensive Brain Tumor Center

    Every metastatic brain tumor, and every patient, is different. The specialists at Johns Hopkins take the time to determine which treatment or combination of treatments will be the most effective for you.

    What’s The Outlook For People With A Brain Tumor

    The outcome for people with brain tumors varies greatly. Factors that can affect prognosis include the tumorâs type, grade, and location successful removal of all of the tumor and your age and overall health.

    In many people, doctors can successfully treat a brain tumor. Other people live active and fulfilling lives with brain tumors that do not cause symptoms.

    In some people, brain tumors can recur after treatment. These people may need to continue treatments, including chemotherapy or radiation, to keep the tumor from growing or spreading. After brain tumor treatment, you should follow up with your doctor regularly.

    The Most Common Brain Tumor: 5 Things You Should Know

    A brain tumor diagnosis can sound like a life-threatening situation. But although the symptoms of most brain tumors are the same, not all tumors are malignant.

    In fact, meningioma is the most common brain tumor, accounting for about 30 percent of them. Meningioma tumors are often benign: You may not even need surgery.

    Here are five key meningioma facts you need to know:

    Glioblastoma: How Fast Do They Grow

    A 57 year old female presented with new onset seizure. An MRI was obtained showing a lesion in the right frontal/parietal region. You can see there is some mass effect, slight effacement of the ventricle, and a whiff of enhancement. Needle biopsy returned astrocytoma, WHO Grade 3.

    Surgical resection was recommended, but the patient chose instead to pursue external beam radiation and oral chemotherapy in the form of temozolomide.

    Unfortunately, she now presents three months later with confusion, agitation, and left arm weakness. An MRI is again obtained. The tumor shows marked growth and different signal characteristics. You see that the mass is inhomogeneously enhancing, with marked mass effect, surrounding edema, ventricular effacement, and minimal midline shift.

    At this time the patient requests craniotomy for surgical debulking. The final pathologic diagnosis is Glioblastoma, WHO Grade 4.

    This shows how rapidly a glioma can grow and transform to a higher grade, in this case just three months.

    Not All Cells Divide At The Same Time

    Growth rates and doubling time matter, but in real life there are exceptions to every rule. Growth rate estimates are based on an exponential model. For example, one cell becomes two, two become four, four then become eight, and so on. In real life, however, not all cells are dividing at the same rate and at the same time.

    Different types of cancer have different “growth fractions,” a measure of the proportion of cells that are in an active cell cycle. Some cancers, such as childhood leukemias, have a very high growth fraction, meaning a large number of cells is dividing at a specific time. Other cancers, such as breast cancer, have a low growth fraction.

    What Causes A Brain Tumor

    Doctors are not sure what causes most brain tumors. Mutations or defects in genes may cause cells in the brain to grow uncontrollably, causing a tumor.

    The only known environmental cause of brain tumors is having exposure to large amounts of radiation from X-rays or previous cancer treatment. Some brain tumors occur when hereditary conditions are passed down among family members.

    Many brain tumors grow slowly, particularly benign brain tumors. Some benign tumors may be safely monitored by a medical team for months or even years rather than being immediately removed with surgery. Many malignant tumors, though, are more aggressive and fast-growing and likely need prompt treatment.

    Types Of Brain Tumors

    Primary brain tumors come from cells that make up the brain and central nervous system. Theyâre named for the kind of cell in which they first form. There are more than 100 kinds of brain tumors. The most common types in adults are:

    • Gliomas. These tumors start in the glial cells, which are cells that help keep nerves healthy. Theyâre most often cancer. There are several categories of gliomas, based on which specific cells they target. Astrocytomas are most common in adults. A glioblastoma is the most aggressive type of glial tumor.
    • Meningiomas. These form in the meninges, the thin layer of tissue that covers the brain and spinal cord. They arenât cancer, but they can cause problems by pressing on your brain.
    • Schwannomas. These damage the protective coating of nerve cells. They arenât cancer, but they often cause hearing loss or problems with balance.
    • Pituitary adenomas. These form on the pituitary gland, which sits at the base of your brain. It makes important hormones. These tumors usually arenât cancer and are slow growing.

    Is Neuroendocrine Cancer Slow Growing Or Aggressive

    Neuroendocrine cancers are types of cancers that originate from cells in the neuroendocrine system. These cells are located throughout the body in the organs and are responsible for controlling most of the bodily functions. The cells in the neuroendocrine system receive signals from the nervous system then respond by releasing hormones.

    Neuroendocrine tumors are grouped depending on where they originate in the body, for example, gastrointestinal neuroendocrine tumors which develop in organs in the gastrointestinal tract small intestines, stomach, rectum, appendix, and esophagus. There are also lung neuroendocrine tumors e.g. small cell and large cell lung neuroendocrine carcinomas as well as typical and atypical carcinoid tumors. Another common type of neuroendocrine tumors is the pancreatic neuroendocrine tumors which are named based on the hormone they produce. The PNETs are gastrinomas, glucagonoma, VIPoma, insulinoma, and somatostatinoma.

    Side Effects Of Cancer Treatment

    Kids who undergo radiation therapy or chemotherapy for a brain tumor often have side effects. These can include fatigue , nausea, vomiting, and hair loss. These side effects go away when treatment ends.

    Long-term effects of treatment, called “late effects,” also can happen. These include learning disabilities, seizures, growth disorders, hearing and vision problems, and the possibility of developing a second cancer, including a second brain tumor.

    Because these problems sometimes aren’t noticed until years after treatment, careful observation and regular screenings are needed to catch them as early as possible.

    What Side Effects Does Chemotherapy Cause When Treating Brain Tumors


    Many people have heard of the side effects chemotherapy can cause when treating other cancers nausea, vomiting, mouth sores, etc. But a number of the brain cancer chemotherapy drugs we use are a little different and may not cause such severe side effects. Your team will discuss the possibilities with you before you commit to a treatment plan.

    Most Meningiomas Do Not Spread

    It can be shocking for someone to be diagnosed with a meningioma especially a large one but these tumors are usually benign. This means that the tumor cells are not likely to spread to other parts of the body.

    That said, meningiomas can quietly grow for years without causing any problems and they can get surprisingly large.

    What Kind Of Treatment Follow

    Regular follow-up treatment is extremely important after brain tumor treatment. Besides regular physical and neurological exams and blood tests, you may need periodic MRI, MR spectroscopy, perfusion or diffusion MRI, and/or CT exams. Doctors rarely use positron emission tomography scans in brain tumor patients. However, they may use PET to monitor disease outside of the brain . Your doctor may also recommend home care, occupational or vocational therapy, pain management, physical therapy, and participation in support groups.

    This follow-up care will help your doctor to:

    • spot any sign that the tumor is returning
    • monitor the health of your brain
    • identify and treat the side effects of chemotherapy or radiation therapy
    • detect the presence of other types of cancer at the earliest possible stage

    What Are The Types Of Brain Tumors

    Doctors classify brain and central nervous system tumors based on where they form and the kind of cells they involve.

    Brain tumors that are usually benign include:

    • Acoustic neuroma:These tumors occur on the vestibular nerve . Acoustic neuromas are also called vestibular schwannomas.
    • Gangliocytoma: These central nervous system tumors form in neurons .
    • Meningioma:These are the most common type of primary brain tumors. Meningiomas develop slowly. They form in the meninges, the layers of tissue that protect the brain and spinal cord. In rare cases, a meningioma can be malignant.
    • Pineocytoma: These slow-growing tumors form in the pineal gland, which is located deep in the brain and secretes the hormone melatonin.
    • Pituitary adenoma: These tumors form in the pituitary gland, which is located at the base of the brain. The pituitary gland makes and controls hormones in the body. Pituitary adenomas are usually very small.
    • Chordoma: These slow-growing tumors typically begin at the base of the skull and the bottom part of the spine. They are mostly benign .

    Cancerous brain tumors include:

    • Glioma:These tumors develop in glial cells, which surround and assist nerve cells. Two-thirds of cancerous primary brain tumors are gliomas. Types of gliomas include:
    • Astrocytoma: Astrocytomas form in glial cells called astrocytes.
    • Glioblastoma: Aggressive astrocytomas that grow quickly are glioblastomas.
    • Oligodendroglioma: These uncommon tumors begin in cells that create myelin .
