Specific Treatments For Brain Tumors

Malignant Brain Tumors

Treatments for brain tumors include the following:

  • Craniotomy

  • Shunts

  • Stereotactic techniques

Craniotomy is done when possible. This procedure involves opening the skull. Some brain tumors can be removed with little or no damage to the brain. However, many grow in areas that make removal by traditional surgery difficult or impossible without destroying essential structures.

For craniotomy, part of the scalp is shaved. Then, an incision is made through the skin. A high-speed drill and a special saw are used to remove a small piece of bone above the tumor. The tumor is located and removed using one of the following:

  • A scalpel may be used to cut out the tumor.

  • A laser may be used to vaporize the tumor.

  • A device that emits ultrasound waves may be used to break the tumor apart, so that the pieces can be suctioned out .

Lasers and ultrasound devices are used to remove tumors that would be difficult to cut out. Usually, the bone is then replaced, and the incision stitched closed.

Traditional surgery sometimes causes brain damage that can lead to symptoms such as partial paralysis, changes in sensation, weakness, and impaired mental function. Nevertheless, removing a tumorwhether cancerous or noncancerousis essential if its growth threatens important brain structures. Even when a cure is impossible, surgery may be useful to reduce the tumors size, relieve symptoms, and help doctors determine whether other treatments, such as radiation therapy or chemotherapy, are warranted.

Side Effects Of Treatment

Some people who have had a brain tumour can develop side effects from treatment months or years later, such as:

  • cataracts
  • problems with thinking, memory, language or judgement

Rarely, a stroke might happen.

If you or someone you care for has any worrying symptoms that develop after brain tumour treatment, see your doctor.

If you think it’s a stroke, dial 999 immediately and ask for an ambulance.

Laser Interstitial Thermal Therapy

Laser Thermal Ablation is a newer technique that some centers are using to treat smaller tumors particularly in areas that may be more difficult to reach using previous open surgery procedures. This involves placing a tiny catheter within the lesion, possibly completing a biopsy, then using laser to thermally ablate the lesion. This technique is only more recently used in brain tumor treatments, therefore the long term efficacy has not been established.

How Are Brain Tumors Diagnosed

Brain Tumor Stages

Diagnosis of a brain tumor begins with a physical exam and a look at your medical history.

The physical exam includes a very detailed neurological examination. Your doctor will conduct a test to see if your cranial nerves are intact. These are the nerves that originate in your brain.

Your doctor will look inside your eyes with an ophthalmoscope, which is an instrument that shines a light through your pupils and onto your retinas. This allows your doctor to check how your pupils react to light. It also allows your doctor to look directly into your eyes to see if theres any swelling of the optic nerve. When pressure increases inside the skull, changes in the optic nerve can occur.

The doctor may also evaluate your:

  • muscle strength
  • ability to do mathematical calculations

Your doctor may order more tests after they finish the physical exam. These could include:

Types Of Brain Cancer

Astrocytomas, which are the most common CNS tumor, arise anywhere in the brain or spinal cord, and develop from small, star-shaped cells called astrocytes. In adults, astrocytomas most often occur in the cerebrum, the largest part of the brain. The cerebrum uses sensory information to tell us whats going on around us and how the body should respond. The cerebrum also controls speech, movement and emotions, as well as reading, thinking and learning.

Brain stem gliomas are a type of astrocytoma that forms in the brain stem, which controls many vital functions, such as body temperature, blood pressure, breathing, hunger and thirst. The brain stem also transmits all the signals to the body from the brain. The brain stem is in the lowest part of the brain and connects the brain and spinal cord. Tumors in this area can be difficult to treat. Most brain stem gliomas are high-grade astrocytomas.

Glioblastoma multiforme, also known as glioblastoma, GBM or grade 4 astrocytoma, is a fast-growing, aggressive type of CNS tumor that forms on the supportive tissue of the brain. Glioblastoma is the most common grade 4 brain cancer. Glioblastomas may appear in any lobe of the brain, but they develop more commonly in the frontal and temporal lobes. Glioblastomas usually affect adults.

Aside from astrocytomas, there are a number of different primary brain tumors and other nervous system tumors that form from glial cells. They include:

Brain Tumors In Children

Brain tumors are the most common solid tumor in children and adolescents, affecting about 5,000 children in the U.S. each year. Several different types of brain tumors can occur in children, including astrocytomas , gliomas, ependymomas and medulloblastomas.

Types Of Brain And Spinal Cord Tumors In Adults

There are two main types of brain and spinal cord tumors:

  • Tumors that start in the brain or spinal cord are called primary brain tumors.
  • Tumors that start in another part of the body and then spread to the brain or spinal cord are called metastatic or secondary brain tumors.

In adults, metastatic tumors to the brain are actually more common than primary brain tumors, and they are treated differently. This information is about primary brain tumors.

Unlike cancers that start in other parts of the body, tumors that start in the brain or spinal cord rarely spread to distant organs. Even so, brain or spinal cord tumors are rarely considered benign . They can still cause damage by growing and spreading into nearby areas, where they can destroy normal brain tissue. And unless they are completely removed or destroyed, most brain or spinal cord tumors will continue to grow and eventually be life-threatening.

Primary Vs Metastatic Brain Tumors

Malignant Brain Tumor Clinical Trials What You Need to Know

Primary brain tumors are tumors that start in the brain. Examples of tumors that most often originate in the brain include meningioma and glioma. Very rarely, these tumors can break away and spread to other parts of the brain and spinal cord. More commonly, tumors spread to the brain from other parts of the body.

Metastatic brain tumors, also called secondary brain tumors, are malignant tumors that originate as cancer elsewhere in the body and then metastasize to the brain. Metastatic brain tumors are about four times more common than primary brain tumors. They can grow rapidly, crowding or invading nearby brain tissue.

Common cancers that can spread to the brain are:

Treating Malignant Brain Tumours

If you have a malignant brain tumour, you’ll usually need surgery to remove as much of it as possible. Radiotherapy and/or chemotherapy may then be used to treat any remaining cancerous tissue.

The aim of this is to remove or destroy as much of the tumour as possible, ideally getting rid of the cancerous cells completely. However, this isn’t always possible and most malignant brain tumours will eventually return after treatment.

If your tumour does return after treatment, or you have a secondary brain tumour , a cure isn’t usually possible. Treatment can instead be used to control your symptoms and prolong life.

What Are The Complications Associated With A Brain Tumor

Some people with a brain tumor â whether it is benign or malignant â experience complications as the tumor grows and presses on surrounding tissue. These complications include:

  • Faster or slower breathing and pulse rates.
  • Numbness that interferes with feeling pressure, heat or cold on the body.
  • Weakness or inability to move a leg or arm on one side of the body.
  • Vision, hearing and smelling problems.

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: 40.2%

Glioblastoma (grade IV)

Endoscopic removal of meningiomas through the nose

  • olfactory groove meningiomas

  • olfactory groove meningiomas
  • Tumor embolization prior to surgery
  • In some cases, your surgeon may choose to reduce the blood supply to the tumor by ordering an embolization procedure.
  • Embolization involves threading a thin tube up the leg veins or arteries directly into the blood vessels that feed the tumor. Then a glue-like clotting substance is injected to choke off and shrink the tumor.
  • Radiation
  • For those ineligible for surgery or with incomplete surgical removal, either conventional radiation or fractionated stereotactic radiosurgery can slow or stop the growth of meningiomas.
  • Radiation treatment is often considered for deep, surgically inaccessible tumors, or tumors in elderly patients.
  • Younger patients need to be counselled about the risk of developing radiation-induced cancer 10 or more years after radiation treatment. Fortunately, the chances of this happenning appear to be very small.
  • Meningiomas have sharp margins and rarely invade neighboring tissue, thus they are ideal tumors for focused, shaped radiation fields using the .
    • Surgery
    • For tumors in favorable locations, up to 85% of meningiomas are curable with surgery.
    • Location, the amount of the tumor left after surgery, and the skill of the neurosurgeon are the important elements in predicting a successful result.

    About Primary Brain Tumors

    A primary brain tumor is a tumor that starts in the brain. A primary brain tumor is often described as “low grade” or “high grade.” A low-grade tumor generally grows slowly, but it can turn into a high-grade tumor. A high-grade tumor is more likely to grow faster.

    In adults, secondary brain tumors, also called brain metastases, are much more common than primary tumors.

    What Causes Primary Brain Tumors

    Many advances have been made in our understanding of brain tumors in recent years, especially for the more common types of malignant brain tumors. These tumors generally have several mutations most of which are present only in the tumor cells and not elsewhere in the body. These mutations tend to be in specific areas of the DNA, and the presence of mutations in the DNA in these regions allows the cells to grow and divide out of control. Much remains to be learned about the cause of these mutations and the manner in which they permit cells to grow and divide abnormally. Even more important, much remains to be learned how knowledge of the causes of these tumors can be used to devise more effective treatments.

    Diagnosing Malignant Brain Tumours

    See your GP if you develop any of the symptoms of a malignant brain tumour, such as a persistent and severe headache.

    Your GP will examine you and ask about your symptoms. They may also carry out a simple neurological examination .

    If they suspect you may have a tumour, or they are not sure what’s causing your symptoms, you’ll probably be referred to a neurologist .

    Malignant Brain Tumor Surgery What You Need to Know

    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.

    What Is A Highly Malignant Brain Tumor

    . Besides, what is considered a large brain tumor?

    Meningiomas grow on the surface of the brain , and therefore push the brain away rather than growing from within it. Most are consideredbenign because they are slow-growing with low potential to spread. Meningioma tumors can become quite large. Diameters of 2 inches

    Similarly one may ask, are all malignant brain tumors fatal?

    More than any other cancer, brain tumors can have lasting and life-altering physical, cognitive, and psychological impacts on a patient’s life. This means malignant brain tumors can often be described as equal parts neurological disease and deadly cancer.

    Types Of Primary Brain Tumors

    There are many types of primary brain tumors. Some cannot be assigned an exact type because the tumors location makes it too difficult to remove for full testing.

    Descriptions of more common brain tumor types in adults are listed below, divided into glioma and non-glioma tumor types. Learn about brain tumors in children in a different guide on this same website.

    Targeted Drug Combo Unprecedented Against Highly Aggressive Brain Tumors

    brain cancer

    A combination of two targeted cancer drugs showed unprecedented, clinically meaningful activity in patients with highly malignant brain tumors that carried a rare genetic mutation, according to a clinical trial report by investigators from Dana-Farber Cancer Institute.

    The drug combination, which blocked an overactive cell-growth signaling pathway, shrank tumors by 50% or more in one-third of 45 patients with hard-to-treat high-grade gliomas, including glioblastomas, the most aggressive brain tumor. The patients were selected for the trial because their tumors carried a genetic mutation known as v600E in the BRAF gene. This mutation is found in only two to three percent of patients with high-grade gliomas but is found in up to 60% of certain types of low-grade gliomas. The study included 13 patients with low-grade gliomas. Of those patients, nine had an objective response to treatment with the drug combination, for a response rate of 69%.

    The two drugs paired in the study were dabrafenib and trametinib. Both drugs target proteins in the MAPK pathway, a signaling chain of proteins that acts as a switch for cell growth and can become stuck in the on position, causing uncontrolled growth leading to tumors.

    The ROAR trial was originally designed and sponsored by GlaxoSmithKline and is currently sponsored by Novartis.

    Dermoid Or Epidermoid Cyst

    These benign growths are due to leftover skin tissue within the head or spinal canal. The skin tissue grows, producing pearly scales that would be analogous to the shedding of dead skin. As this material has nowhere to go , it accumulates and eventually forms a mass. Treatment is surgical, although it may not be possible to cure the cyst, as often the skin cells are firmly adhered to small nerves and blood vessels. Epidermoid cysts contain just the outer layer of skin and its waste, while dermoids also include the deeper layers of skin tissue that produce hair.

    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.

    After A Diagnosis Of Brain Cancer

    After finding out you have brain cancer, you may feel shocked, upset, anxious or confused. These are normal responses. A diagnosis of brain cancer affects each person differently. For most it will be a difficult time, however some people manage to continue with their normal daily activities.

    Your specialist will arrange for a range of health professionals to plan your treatment. This will be based on several factors including the type, size, location and genetic make-up of the cancer as well as, your age and general health, the types of symptoms you have and your needs and preferences.
