Brain Cancer Treatment

 

Brain cancer can interfere with normal brain functions such as speech, movement, thoughts, feelings, memory, vision, and hearing. It is a disease of the brain in which abnormal, cancerous cells grow in the brain tissues. Typically, brain cancer is a developed form of a brain tumour. Primary brain cancer or a brain tumour develops from cells within the brain.

However, all brain tumours are not brain cancer. But one thing to note is that even benign tumour can cause serious problems by increasing intracranial pressure or obstruct vascular structures or cerebrospinal fluid flow in the brain.

Different types of cells in the brain such as gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal (medulloblastomas) can become cancerous. Gliomas have several subtypes, which include astrocytomas, oligodendrogliomas, ependymomas, and choroid plexus papillomas.

Types of Brain Cancers

There are two types of brain cancer, including:

  • Primary brain cancers: Primary brain cancers result when cancer cells develop in the tissues of the brain itself. Primary brain cancer cells may travel short distances within the brain but generally would not travel outside of the brain itself.
  • Secondary brain cancers: Secondary brain cancer is called metastatic brain cancer. It occurs when cancer develops elsewhere in the body and spreads to the brain. Primary cancer tissues can spread via direct extension, or through the lymphatic system or through the bloodstream.

Metastatic cancer in the brain is more common than primary brain cancer. They are usually named after the tissue or organ where cancer first develops. Metastatic lung or breast cancer in the brain is the most commonly found brain cancers.

Brain Cancer Causes

The exact brain cancer cause is still unknown. However, its occurrence has been linked to several risk factors, including the following:

  • Exposure to radiation
  • HIV infection
  • Inherited abnormality
  • Smoking
  • Exposure to environmental toxins
  • Exposure to chemical toxins, especially those used in rubber industry and oil refinery

Brain Cancer Symptoms

Some types of brain cancers such as meningeal and pituitary gland may produce few or no symptoms. Some of the brain cancer symptoms typically experienced by patients include:

  • Difficulty walking, seizures, dizziness and vertigo
  • Extreme fatigue and muscle weakness
  • Severe headaches and blurry vision
  • Sleepiness, nausea, and vomiting
  • Reduction in mental alertness, capacity or memory
  • Difficulty in speaking, impaired voice or inability to speak
  • Personality changes and hallucination
  • Weakness on one side of the body and coordination problems
  • Reduced touch sensation
Deep Brain Stimulation

Deep brain stimulation (DBS) is a neurosurgical procedure that involves implantation of electrodes within the specific targeted areas of the brain. It is used to treat a variety of disabling neurological symptoms. Deep brain stimulation procedure can be opted for treating a number of neurological conditions, including Parkinson's disease, Essential tremor, Dystonia, Epilepsy, Tourette syndrome, obsessive-compulsive disorder and chronic pain. Deep brain stimulation uses a neurostimulator, commonly referred to as deep brain stimulator,  to deliver electrical stimulation to targeted areas in the brain that control movement.

The impulse sent by deep brain stimulator interferes with and blocks the electrical signals that cause tremor and other Parkinson’s disease symptoms. The targeted areas most often include the thalamus, subthalamic nucleus and globus pallidus. Deep brain stimulation procedure has a long history of research. It was first introduced in 1987 and The Food and Drug Administration (FDA) approved deep brain stimulation treatment for essential tremor and Parkinson's disease in 1997.

What is deep brain stimulation treatment?

Deep brain stimulation treatment is recommended for people who have had Parkinson’s disease for at least four years, are still getting benefited from medications, but have motor complications, such as significant on-off time periods. Brain stimulation therapy works by inactivating the parts of the brain that cause Parkinson's disease symptoms. However, DBS Parkinson does not damage the healthy brain tissue by destroying nerve cells. It blocks electrical signals from targeted areas of the brain.

Deep brain stimulation treatment has proven effective in most of the cases, but it could potentially result in serious complications and side effects. This is the main reason why deep brain stimulation treatment is used only for patients whose symptoms are not appropriately controlled with medications.

Laminectomy

Laminectomy is also known as decompression surgery. In this surgical procedure, a part of the vertebral bone called lamina is removed to create additional space. The lamina is the back part of the vertebrae that covers the spinal canal. Removing the lamina enlarges the spinal canal and thus, helps relieve pressure on the nerves and the spinal cord. Bony growths, especially in people with spinal arthritis, may put an additional pressure on the spinal cord. It may cause severe back pain and in some severe cases, can even cause paralysis. Narrowing of the space between the vertebrae is also known as spinal stenosis.

Laminectomy surgery, which is a form of spinal stenosis treatment, helps relieve pressure on the spinal cord and the nerves by creating a room between the vertebrae and the cord. When the pressure on the spinal cord in the case of lumbar spinal stenosis is relieved by creating a space between the lumbar vertebrae, the procedure is known as lumbar laminectomy. During a lumbar laminectomy, the surgeon may even remove the ligaments or bone spurs pressing the spinal cord.

Microdiscectomy

Microdiscectomy is also known as microdecompression or cervical microdiscectomy. It is one of the most commonly performed spine surgery procedures.

Microdiscectomy or cervical microdiscectomy is preferred for patients with a lumbar herniated disc. The main goal of a discectomy is to relieve the pressure on a spinal nerve root by removing the material causing the pain. Traditionally, this purpose was solved by an open technique called lumbar discectomy surgery, which involves making a large incision to cut some of the back muscles, leading to a slow and painful recovery. Nowadays, an advanced form of surgery called microdiscectomy can achieve the same goal that too with the help of a small incision and fewer injury to back muscles. As a result, the recovery takes less time and is less painful.  A special microscope is used in microdiscectomy to view the disc and nerves. The larger view allows the surgeon to make a smaller incision, causing less damage to the surrounding tissues.

 

When is microdiscectomy needed?

Sciatica is a condition caused by compression of the spinal nerve, which generally results in chronic pain in the legs of the patients. This compression of the spinal nerve is frequently the result of a herniated lumbar disc.  As a herniagrows, the damaged tissue extends into the spinal column and pushes on the nerves. This condition causes the nerves to send pain signals to the brain and the brain interprets the pain source to be coming from the legs.

Most commonly, sciatica heals naturally or with the help of medication in a few weeks. But, if sciatica lasts more than 12 weeks after taking oral medicines, patients may benefit from discectomy. Discectomy is also used for the treatment of spondylosis and lumbar spinal stenosis. While spondylosis occurs due to degenerative osteoarthritis of the vertebrae, lumbar spinal stenosis occurs due to narrowing of the spinal canal leading to nerve compression. The latter may also warrant the need for a spinal stenosis surgery.

Scoliosis Surgery

Scoliosis is a medical condition, characterized by an abnormal curve of the spine. There are different types of scoliosis, depending on the exact location of the abnormal curve and the age of the patient. The abnormal curvature of the spin is the most common symptom of scoliosis.

The spinal curve looks straight when looking from the front. The normal curved of the spine visualized from the sides are known as kyphosis and lordosis. People with scoliosis develop an additional curve in their spine to five it a C-shaped or an S-shaped appearance.

Scoliosis can affect adults as well as children. However, it is most common in patients aged above 10. Additionally, this condition is more common in girls than boys. A sideways curvature of the lumbar vertebrae is also known as lumbar scoliosis.

The most common test used to diagnosed scoliosis is Adam’s Forward Bend Test. During this test, the doctor asks the suspected patient to bend at the waist with palms touching the floor and knees straight. In this position, any abnormality in the curvature of the spine is clearly visible.

Symptoms of Scoliosis

There are no specific symptoms of scoliosis. The appearance of the abnormal curvature of the spine is most often the first sign of scoliosis. The diagnosis of this condition most commonly takes place during an examination at school and college.

In severe cases of scoliosis, breathing difficulty, chest pain, and shortness of breath may appear. Scoliosis is not usually painful. But it can cause neck pain, back pain, abdominal pain, rib pain, and muscle spasms.

Spinal Fusion

Spinal fusion surgery is a type of a spinal procedure used to join two or more bones permanently in the spine and to prevent movement between them. The bones that are joined are called as vertebrae. Spinal fusion surgery is performed along with other surgical procedures such as foraminotomy or laminectomy and after diskectomy in the neck. It is required if the patient has an injury or a fracture of the vertebrae. The spine will become weak due to an infection or tumors. Spinal fusion is also performed in abnormal curvatures that result from scoliosis or kyphosis.
