What is a brain chordoma?

A chordoma is a form of bone cancer that can occur anywhere along the length of the spine, from the base of the skull to the lower back. When it occurs at the base of the skull, it is known as skull base chordoma. Because of its location in the base of the skull, it commonly affects vital structures.

Is a chordoma a brain tumor?

Skull base chordomas are sometimes called brain tumors because they grow inside the skull toward the brain; however, they do not actually develop from brain cells. Mobile spine. The remaining 20 percent of chordomas form in the spine at the level of the neck, chest, or lower back.

What is the survival rate of chordoma?

Chordomas are malignant and potentially life threatening tumors. Currently the median survival in the United States is about 7 years. The overall survival rates are 68% at 5 years and 40% at 10 years. Complete surgical resection offers the best chance for long-term survival.

What kind of cancer is chordoma?

Chordoma is a rare type of bone cancer that happens most often in the bones of the spine or the skull. It most often forms where the skull sits atop the spine (skull base) or at the bottom of the spine (sacrum).

How do you get chordoma?

Chordomas form from the left-over cells that were important in the development of the spine before birth. These cells are called notochord cells. When the notochord cells don’t disappear after birth, they can turn into chordomas. Chordomas grow very slowly.

What is the cause of chordoma?

The underlying causes of chordoma are unknown. Most cases arise spontaneously and are not due to an inherited genetic change. A prevailing theory is that acquired genetic abnormalities or mutations result in cancerous growth of notochordal remnants.

How long does it take for a chordoma to grow?

Chordomas grow very slowly. Many people don’t notice any change in their bodies for years. When they do start to have symptoms, it can take a while for the chordoma to be discovered and diagnosed. Most people are diagnosed with chordoma in their 50s and 60s.

Is chordoma life threatening?

When chordomas metastasize (spread) to other parts of the body, or if they grow large and begin to press on critical parts of the brain, they can become life threatening. Even when chordomas have not spread, they can grow very large and damage nerves in the spine and brain, causing disability that may be permanent.

Is there a cure for chordoma?

With appropriate treatment, many chordoma patients will live for a decade or more, and some can be cured.

Can chordoma be removed?

Clival chordomas are locally invasive tumors that arise in the base of the skull. Clival chordomas are ideally treated with maximal safe surgical removal followed by focused radiotherapy. Fortunately, the majority of clival chordomas can be removed via the nose using an endoscopic endonasal approach.

Can MRI detect chordoma?

Among imaging methods that contribute to the diagnosis, MRI is particularly reliable; this modality is highly accurate in assessing the soft-tissue extent of chordomas and in evaluating involvement of adjacent tissues. T1- and T2-weighted sequences are needed before and after gadolinium injection.

How do I know if I have chordoma?

Types of imaging tests An MRI is the best way to see a chordoma and how it is affecting the tissue around it, such as muscles, nerves, and blood vessels. No matter where the tumor is located, an MRI of the entire spine should be performed to see if the tumor may have spread to or developed in other areas of the spine.

What is a chordoma?

Chordomas are tumors that can occur anywhere within the spine or the base of the skull. The two most common locations for chordomas are the lower back (sacral area — approximately one-third to one-half of chordomas) and the base of the skull (approximately one-third of chordomas).

What happens if you have a chordoma in your brain?

If the chordoma becomes large enough to block the flow of cerebrospinal fluid in the brain, than the buildup of fluid can increase pressure in the brain, leading to headaches, nausea, and vomiting. Chordomas that develop in the spinal cord may cause pain, weakness, or numbness along the back, arms, or legs.

How is chordoma in the base of the skull treated?

Depending on the size and location of the tumor, patients with chordoma in the base of their skulls may be a candidate for minimally invasive skull base surgery. This operation involves removing the tumor endoscopically, using special tools and scopes that pass through small openings – in this case, the nasal passages.

Where do chordomas form in the spine?

The remaining 20 percent of chordomas form in the spine at the level of the neck, chest, or lower back. These areas are the cervical [sUHR-vi-kuhl], thoracic
