What are oligodendroglioma tumors?

Oligodendrogliomas are commonly found in the white matter and the outer layer of the brain, called the cortex, but can form anywhere in the CNS. These tumors are called oligodendrogliomas because the cells resemble oligodendrocytes, a type of brain cell that supports and insulates nerve fibers in the CNS.

What is the treatment for Grade 3 oligodendroglioma?

Grade 3 oligodendrogliomas are usually treated with surgery soon after diagnosis. This is usually followed by a combination of radiotherapy and chemotherapy because oligodendrogliomas are often ' diffuse ', which means they're more difficult to remove completely.

Is oligodendroglioma same as glioblastoma?

Their names refer to the kind of cells in which they begin: Astrocytoma affects the glial cells called astrocytes. The most aggressive astrocytoma is a glioblastoma, which is also called a glioblastoma multiforme. Oligodendroglioma affects the glial cells called oligodendrocytes.

What is the difference between astrocytoma and oligodendroglioma?

Oligodendrogliomas arise from oligodendrocytes – fried egg-shaped cells within the brain. The role of normal oligodendrocytes is to form a covering layer for the nerve fibers in the brain. Astrocytomas are gliomas that arise from astrocytes – star-shaped cells within the brain.

What is an oligodendroglioma?

Oligodendroglioma is a primary central nervous system (CNS) tumor. This means it begins in the brain or spinal cord. To get an accurate diagnosis, a piece of tumor tissue will be removed during surgery, if possible. A neuropathologist should then review the tumor tissue.

Is oligodendroglioma a type of glioma?

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.

Can oligodendrogliomas be caused by radiation?

Genes may be mutated (changed) in many types of cancer, which can increase the growth and spread of cancer cells. The cause of most oligodendrogliomas is not known. Exposure to radiation and certain gene changes that can be passed down through families have been linked to a higher chance of developing oligodendrogliomas.

What is an oligodendroglioma?

Oligodendrogliomas are brain tumors arising from oligodendrocytes, a type of cell that makes up the supportive (glial) tissue of the brain. They can be low-grade (grade II) or high-grade (grade III, also called anaplastic). While they can be found anywhere within the cerebral hemisphere, they are most common in the frontal and temporal lobes. They are generally soft, grayish-pink tumors that often contain mineral deposits (calcifications), areas of hemorrhage, and/or cysts. They tend to grow slowly and may be present for many years before they are diagnosed. Common symptoms include seizures, headaches and changes in personality. Other symptoms vary by the size and location of the tumor. [1] The exact cause of opigodendrogliomas is unknown. Some appear to have a chromosome abnormality involving loss of chromosomes 1p and 19q. [1] [2] Treatment generally involves surgical removal of the tumor followed by radiation therapy and/or chemotherapy. Recurrent tumors may need additional surgery, radiation and chemotherapy. [1]

What is the diagnosis of oligodendroglioma?

An oligodendroglioma is usually diagnosed after an individual notices symptoms and has been referred to a neurologist, a doctor who specializes in diseases of the central nervous system. A diagnosis of this brain tumor begins with a thorough physical exam during which a neurologist will ask about symptoms such as seizures, persistent headaches, ...

How many chromosomes are in oligodendroglioma?

Each cell in our body has 23 pairs of chromosomes, which carry genes from each of an individual’s parents.

What is the best treatment for oligodendroglioma?

A neuro-oncology team at a major medical center will make a recommendation for the best treatment for an oligodendroglioma based on the type, grade, size, and location of the brain tumor, whether it has spread, the results from the biomarker tests, and the overall health and goals of the individual. Different treatments are often used in combination and require a multidisciplinary team of experts: neurosurgeons, neuro-oncologists, radiation oncologists, neuropathologists, and other specialists. In some cases, if a tumor is not growing or posing any threat to surrounding nerves or tissue, or if the patient is older and surgery is a risk, then monitoring may be the treatment of choice.

What is the grade of oligodenglioma?

Oligodendrogliomas are divided into two types: grade two oligodendrogliomas that grow very slowly. grade three oligodengliomas, also known as anaplastic oligodendroglioma. These grow faster and are more likely to spread. They are more common in older people aged 60-80. Back to the top.

How to treat grade 3 oligodendrogliomas?

Grade 3 oligodendrogliomas are usually treated with surgery soon after diagnosis. This is usually followed by a combination of radiotherapy and chemotherapy because oligodendrogliomas are often ' diffuse ', which means they're more difficult to remove completely.

How is oligodendroglioma treated?

Oligodendroglioma treatment usually involves surgery to remove the tumor. Additional treatments may be necessary if the tumor is aggressive or is more likely to recur.

What is the best way to remove oligodendroglioma?

Your brain surgeon (n eurosurgeon) will work to remove as much of the oligodendroglioma as possible without affecting healthy brain tissue. Specialized surgical techniques, such as awake brain surgery, can help ensure that sensitive brain tissue isn't damaged during surgery.

What is oligodendroglioma?

Oligodendroglioma is a rare brain tumor that begin in a certain type of glial cells. Glial cells are glue-like cells that surround nerve cells and help them function. Your outcome depends on the tumor’s location and grade, and your age and health.

What tests can be done to confirm oligodendroglioma?

Doctors use several tests to confirm a diagnosis of oligodendroglioma. These tests include: Neurological exam: During a neurological exam, your doctor looks for signs of weakness in the body, or changes in your coordination, hearing, vision, and reflexes. These changes can help your doctor identify the part of your brain that the tumor affects.

What tests are used to determine the location of oligodendroglioma?

Imaging tests: CT scans and MRIs help doctors determine the size and location of the tumor. Biopsy: A doctor uses a needle to take a tissue sample from the tumor through a small hole in the skull. A laboratory examines the sample to confirm the diagnosis of oligodendroglioma.

Can you remove oligodendroglioma?

In some cases, it is not possible to remove the entire tumor through surgery alone. Radiation therapy: Cancer specialists called radiation oncologists use high doses of X-rays to destroy what remains of the tumor after surgery. People with oligodendroglioma do not usually have radiation before surgery.

Can you have more than one surgery for oligodendroglioma?

Sometimes people need more than one surgery to remove the whole tumor and ensure it does not return. Some people live symptom-free, active lives with these tumors. In some cases, people with oligodendroglioma need to continue treatments, including chemotherapy or radiation, to keep the tumor from growing or spreading.

What is oligodendroglioma?

Overview. Oligodendroglioma is a rare tumor that occurs in the brain. It belongs to a group of brain tumors called gliomas. Gliomas are primary tumors. This means they have originated in the brain rather than spreading from elsewhere in the body. Around 3% of all brain tumors are oligodendrogliomas.

What is the best treatment for oligodendrogliomas?

Surgery. Surgery is typically used for treating oligodendrogliomas, particularly if the tumor is low grade. However, surgery often doesn’t completely remove the tumor effectively, so there is a need to use other therapies following the surgery to avoid reoccurrence.

Can oligodendrogliomas be removed?

There are many treatment options available and oligodendrogliomas appear to respond well to treatment. It’s unusual to be able to completely remove the disease, but it’s entirely possible to prolong the life of someone with an oligodendroglioma.

Can oligodendroglioma be mistaken for stroke?

The symptoms you experience will depend upon the size of the tumor and what part of your brain the tumor is growing in. The symptoms of oligodendroglioma are often mistakenly diagnosed as a stroke. As the symptoms progress over time, further diagnosis is often sought.
