Spinal cord tumors are abnormal growths of tissue found inside the bony spinal column, which is a primary component of the central nervous system (CNS). Benign tumors are noncancerous, while malignant tumors are cancerous. Because the central nervous system is found in rigid, bony quarters (i.e., the spinal column), any abnormal growth, whether benign or malignant, can place pressure on sensitive tissues and impair function. [top]
Symptoms of spinal cord tumors generally develop slowly and worsen over time unless they are treated. Spinal cord tumor symptoms include pain, sensory changes and motor problems. [top]
Tumors that originate in the brain or spinal cord are called primary tumors. Most primary tumors are caused by out-of-control growth among cells that surround and support neurons. In a small number of individuals, primary tumors may result from specific genetic disease (e.g., neurofibromatosis, tuberous sclerosis) or from exposure to radiation or cancer-causing chemicals. The cause of most primary tumors remains a mystery. They are not contagious and, at this time, not preventable. [top]
The tumor may be classified as benign or malignant and given a numbered score accordingly. This score can help doctors determine how to treat the tumor and predict the likely outcome for the patient. [top]
The three most commonly used treatments are surgery, radiation and chemotherapy. Doctors also may prescribe steroids to reduce swelling inside the CNS.
IMRT radiosurgery The spinal cord can only tolerate certain amounts of radiation. Intensity-modulated radiation therapy (IMRT) can treat paraspinal tumors of any shape or size while at the same time sparing the greatest amount of normal tissue. This highly advanced technique involves using digital images of the tumor to coordinate a three-dimensional approach in which beams of radiation are delivered to the tumor. The radiation is controlled and therefore can better target the region where the tumor resides with a more concentrated dosage. IMRT radiosurgery represents a significant advance within the field of spinal tumor treatment and is expected to eventually become the standard treatment for primary and metastatic tumors. [top]
