While surgery is increasingly recommended for benign and malignant primary spinal cord tumors, the role of surgery in spinal metastasis, or cancer that has spread to the spine, is controversial. Recent developments in imaging as well as new surgical tools and techniques, such as ultrasonic aspirators and lasers, have significantly expanded the role of surgery as an intervention.
For metastatic tumors with spinal cord compression, some neurosurgeons may perform surgery in selected patients to relieve pressure and pain, reconstruct or stabilize the spine, preserve mobility and bowel and bladder function, and to maximize quality of life. Some doctors may only recommend surgery for patients with a single metastatic tumor and no evidence of cancer growing at another site.
Most patients with primary spinal cord tumors will not require radiation therapy. Radiation, however, is used to treat spinal cord compression due to metastatic cancer or cancer that has spread from other locations. Other targets of radiation include some primary cancers of the spine and more rarely, benign or low-grade spinal cord tumors that cannot be completely removed surgically.
The spinal cord is even more sensitive to the effects of radiation than the brain. Our radiation oncologists work carefully to minimize the risk of radiation-induced damage to normal spinal tissue since it can be progressive and irreversible. The thoracic spinal cord segments, or those located near the chest where half of all spinal tumors occur, are the most sensitive to the effects of radiation.
Radiosurgery with an advanced device called the CyberKnife may be an option for some patients. The CyberKnife is a painless, non-invasive threatment that delivers high doses of precisely targeted radiation to destroy tumors or lesions. Radiosurgery minimizes radiation exposure to healthy tissue surrounding the tumor.
The CyberKnife uses a robotic arm to deliver highly focused beams of radiation. The flexibility of the robotic arm makes it possible to treat areas of the body, such as the spine and spinal cord, that cannot be treated by other radiosurgery techniques.
Chemotherapy, similar to that used for brain tumors, may be recommended in adults for spinal gliomas that progress after surgery and radiation.
Chemotherapy is the use of drugs to kill cancer cells. Your doctor may use just one drug or a combination, usually giving the drugs by mouth or by injection into a blood vessel or muscle. Intrathecal chemotherapy involves injecting the drugs into the cerebrospinal fluid.
Chemotherapy is usually given in cycles: a treatment period followed by a recovery period, then another treatment period, and so on. Patients often do not need to stay in the hospital for treatment. Most drugs can be given in the doctor's office or the outpatient clinic. However, depending on the drugs used, the way they are given and the patient's general health, a short hospital stay may be necessary.
