Chordoma is a rare form of bone cancer located in the skull and spine. It is a slow growing cancer that has shown to metastasize to lungs, liver, lymph nodes and skin in 20-30% of affected people. This type of bone cancer has a tendency to relapse. The incidence of chordoma is 1 in 1 million people.
The symptoms a patient may experience depend upon the location of the tumor. For patients with a tumor in the lower back, symptoms include low back pain, leg pain, leg weakness/numbness, and bladder and/or bowel incontinence. Patients with a tumor at skull base may have headaches, blurred vision, and/or double vision.
Diagnosis and treatment
Noninvasive imaging studies such as CT and MRI may be used to evaluate this tumor. Treatments for chordoma include surgery followed by radiation therapy. Chemotherapy has showed not to be an effective treatment for chordoma. With maximal treatment, the average lifespan of a person with this condition is 5 years, though some patients may survive the disease. Scientists are conducting research in order to provide better treatments for chordoma.
