Often these doctors work at large, specialized institutions. Biopsy: A biopsy is a surgical procedure to remove a small piece of tumor in order to confirm the diagnosis. The sample is examined under the microscope by a pathologist who determines the type of the tumor.

For Patients

A biopsy can be performed as part of the surgery to remove the tumor or as a separate procedure. There are two different approaches for performing a biopsy for brain tumors. An open biopsy involves exposing the tumor and then removing a small portion of it.

A needle biopsy is performed by making an incision in the skin, drilling a small hole into the skull, inserting a narrow, hollow needle through the hole and into the tumor, and drawing up a small amount of tumor into the needle. A needle biopsy may also be conducted with the assistance of computers and scanning equipment, including MRI or CT, in order to increase the precision of the procedure. This procedure is called stereotactic needle biopsy and is useful for patients with deep or multiple tumors.

Stereotactic techniques are discussed further in the Surgical Techniques section. Craniotomy: The most commonly performed surgery for removal of a brain tumor is called a craniotomy. In preparation for a craniotomy, a portion of the scalp is usually shaved, and an incision is made through the skin. Using specialized equipment, a surgeon removes a piece of bone to expose the area of brain over the tumor. The dura mater the outermost layer of the brain tissue is opened, the tumor is located and then removed resected. After the tumor is removed, the bone is usually replaced and the scalp stitched shut.

In a conventional craniotomy, surgeons guide themselves by what they see, their knowledge of anatomy, and their interpretation of the pre-operative scans. During stereotactic surgery, surgeons may rely on a computer to help direct the craniotomy. This approach is discussed further in the Surgical Techniques section below.

Shunt: Some patients with brain tumors develop increased intracranial pressure. To relieve the pressure, a procedure is conducted to drain excess or blocked fluid. A shunt is a narrow piece of flexible tubing called a catheter that is inserted into a ventricle in the brain. The other end of the tubing is threaded under the scalp toward the neck, then, still under the skin, threaded to another body cavity where the fluid is drained and absorbed. The body cavities used for drainage are the right atrium of the heart and, more commonly, the abdominal cavity. Compared to other surgical treatments for brain tumors, the procedure to implant a shunt is relatively minor.

A small hole is drilled in the skull through which the catheter is threaded into a ventricle. A small incision is made in the abdomen or the chest, depending on which cavity is used for drainage. The other end of the catheter is threaded under the skin to the cavity and then fastened. Some shunts can be temporary and are removed after treatment is completed.

Other shunts are left in place after surgery. Following shunt insertion, many patients, particularly children, show dramatic improvement within days. In others, symptoms of intracranial pressure, such as headaches, might remain for a period of several weeks. Doctors use a variety of techniques to determine what a brain tumor looks like both before and during surgery. Specialized images can be generated that shows what functions the brain tissue near the cancer is responsible for.

Generating images both before and during surgery can increase the likelihood that extensive tumor removal can be achieved while avoiding these critical areas. Before surgery, the location of the brain tumor in relation to other structures and blood vessels must be determined as precisely as possible. To achieve this, a variety of tests are performed. These may include:. Using the information obtained from these tests, the surgeon can plan and even rehearse the operation in order to obtain optimal results.

Evaluation of outcomes in elderly patients who had undergone surgery for brain tumors indicates that those who underwent preoperative MRI experienced better outcomes than those patients who were not evaluated with MRI before surgery. Sophisticated mapping techniques can improve the safety and effectiveness of surgery by locating the exact areas of the brain responsible for speech, comprehension, sensation, or movement.

Brain mapping is also used to help identify the margin of the tumor and to differentiate between tumor, swelling edema , and normal tissue. Direct cortical stimulation: In direct cortical stimulation, a probe passes a tiny electrical current into the brain and delicately stimulates a specific area. The result is a response from the body, such as a visible movement of the corresponding body part. This technique may be employed during surgery to help identify important functional areas. For example, direct cortical stimulation has been used during surgery for gliomas to successfully identify and preserve cortical areas responsible for language and minimize damage to motor function.

In a group of 30 patients who underwent direct cortical stimulation, surgeons were able to effectively identify and preserve language centers. Additionally, the brain tumor was completely removed in 14 of the patients. Of these 60 patients, Evoked potentials: The electrical response of the brain can be measured by stimulating the brain and measuring the resulting activity, or evoked potentials, on brain scanning equipment.

Evoked potentials may be used to map and continuously monitor areas of the brain during surgery. Research indicates that the use of evoked potentials can help doctors identify potential damage to motor function in time for repairs to be made. Researchers evaluated the use of motor evoked potentials MEPs in 51 patients who underwent surgery for gliomas. Using corrective measures, all intraoperative changes in MEPs were reversed in time to prevent an irreversible, complete injury to the motor system.

None of the patients involved in this clinical trial lost motor function at the end of the operation. Researchers have also reported that evoked potentials are useful for accurately identifying the part of the brain that controls sensation in the lower lip, which can be damaged during surgery to remove tumors in patient with gliomas in that region of the brain. This helps distinguish between active, normal brain, and non-active tumor or dead tissue necrosis.

Tests include: blood tests to check your general health and how well your kidneys are working an ECG while you are resting and exercising to check that your heart is healthy breathing tests called lung function tests an echocardiogram a painless test of your heart using sound waves a chest x-ray to check that your lungs are healthy scans such as MRI scan or CT scan Depending on the type of brain tumour you have, you might also have some of the following tests: Blood tests to check for hormone levels or chemical markers.

You might have blood tests to: check the level of hormones if you have a pituitary gland tumour check for certain substances chemical markers if you have a pituitary gland, pineal region or germ cell tumour Chemical markers are substances such as proteins, that can be picked up in the blood.

Surgery is the removal of the tumor and some surrounding healthy tissue during an operation. It is usually the first treatment used for a brain tumor and is often the only treatment needed for a low-grade brain tumor. Removing the tumor can improve neurological symptoms, provide tissue for diagnosis, help make other brain tumor treatments more effective, and, in many instances, improve the prognosis of a person with a brain tumor.

A neurosurgeon is a doctor who specializes in surgery on the brain and spinal column. Surgery to the brain requires the removal of part of the skull, a procedure called a craniotomy.
