Chordoma Treatment in Orange County
Chordoma is a rare type of primary bone cancer usually found in the skull or spine. It accounts for only one percent of central nervous system cancers. It belongs to the group of cancer called sarcoma, which include cancers of the muscle, cartilage and bones.
Slow-growing chordoma may be found at any site along the axial skeleton. It is frequently found at the base of the spine, tailbone (sacral) or base of the skull. Chordoma don’t metastasize to distant parts of the body, but it can spread to surrounding tissues. A chordoma must be removed completely to lessen the chance of recurrence.
There is no known cause for chordoma, neither ways to prevent it. No environmental factors, trauma, or diet are known to be associated with chordomas. However, it is thought to develop from cells present in the embryo while the spine is developing. Chordomas may appear benign or non-cancerous when studied through a microscope, but it’s invasive nature, recurrence rate and location on the spinal cord, it is considered malignant. Chordomas are considered non-hereditary.
The signs and symptoms of a chordoma depend on where the tumor is located in the body and the areas of the body the tumor has affected–usually the organs closest to the tumor. If you have a cervical chordoma (growth in the cervical spine), you might have head or neck pain, neurological changes, diplopia (double vision), paralysis of facial muscles, or tingling or numbness in your arms, hands or shoulders. If you have a sacral chordoma (growth in the sacral spine), you might first notice a lump. In some cases, you may have pain, tingling, numbness or weakness in your legs, feet or hips.
Skull base chordoma symptoms:
- Paralysis of facial muscle or facial pain
- Double vision
- Dizziness or vertigo
- Changes in hearing
- Difficulty swallowing
Sacral chordoma symptoms:
- Numbness or tingling sensation in the legs
- Weakness in the hils, legs and feet
Initial treatment will involve thorough medical history and physical exam, including the patient’s symptoms, personal and family health history. To help detect chordoma, Robert Louis, MD conducts a neurological exam to test a patient’s vision, hearing, balance, coordination, reflexes, memory and the ability to think. To help confirm diagnosis and find the exact location of chordoma, he may require tests and special imaging:
Magnetic resonance imaging (MRI): An MRI uses magnetic fields to produce detailed images of the body. A special dye called a contrast medium is injected into a patient’s vein before the scan to create a clearer picture.
Biopsy: Dr. Louis will perform this technique, which uses a needle guided to the tumor or it can be done during surgery when the surgeon can look at the tumor directly. This process is crucial as it will dictate the best course of treatment and will also give important information about prognosis.
After diagnostic tests are done, Dr. Louis will review all of the results with you and describe the tumor stage, grade and best treatment options.

Endoscopic Endonasal Approach-Chordoma of the skull base may be approached directly using the Endoscopic Endonasal Approach. Robert Louis, MD specializes in this state-of-the-art, minimally invasive surgery in accessesing and removing the tumor through the natural corridor of the nose.

Chemotherapy for Chordoma
Chemotherapy uses drugs to stop cancer cells from growing. Depending on the type and stage of the cancer, chemotherapy may be taken by mouth, injected, or placed directly into the tumor site.
Radiation Therapy for Chordoma
Proton beam radiation is the preferred type of radiation treatment for chordoma. A concentrated dose of radiation is directly sent to the tumor through stereotactic radiosurgery. There are two options for radiation therapy:
External Radiation Therapy- Radiation is directed at the chordoma from an outside source.
Internal Radiation Therapy- Places radioactive material directly in the body near the chordoma.
