Each year, approximately 79,000 people are diagnosed with primary tumors of the central nervous system (CNS), including spinal cord tumors, and about 24,000 of these are malignant.
Spinal cord tumors are abnormal masses of tissue that grow within the spinal canal or near the spinal cord. These tumors can be benign (noncancerous) or malignant (cancerous). Tumors can put pressure on the spinal cord and nerves, which can lead to pain, neurological problems and, in some cases, disability. The impact of a spinal cord tumor on a patient’s health depends on its size, type, location, and growth rate.
Symptoms of spinal cord tumors
The symptoms of spinal cord tumors can vary greatly, depending on the location, size, and growth rate of the tumor. It is important to be alert to any unusual changes in the body and consult a doctor if persistent symptoms are experienced. Some of the most common symptoms include:
Pain:
it may be in the back, neck, or limbs. The pain may be constant, dull, or sharp, and may worsen with activity or at night.
Muscle weakness:
it can affect the legs, the arms, or both. Weakness can be progressive and can make it difficult to walk, write, or perform other daily activities.
Tingling or numbness:
it can affect the limbs, trunk, or face. Numbness or tingling may be constant or intermittent.
Coordination problems:
it can cause difficulty walking, maintaining balance, or performing fine motor movements.
Changes in bowel or bladder habits:
it can cause difficulty urinating or defecating, incontinence, or constipation.
Spinal deformity:
it can be caused by large tumors that put pressure on the vertebrae.
Classification of spinal cord tumors
The classification of spinal cord tumors is essential for understanding their behavior and determining the most appropriate treatment approach. Tumors can be classified according to their location within or around the spinal cord, as well as by the type of cell from which they originate:
According to their location:
Intramedullary tumors: they originate within the spinal cord.
Intradural extramedullary tumors: they develop within the spinal canal but outside the spinal cord, within the dura mater (the membrane that surrounds the spinal cord).
Extradural extramedullary tumors: they develop outside the dura mater, in the bone of the spine or in the surrounding soft tissues.
According to the cell type:
Meningiomas: tumors that originate in the meninges (the membranes that surround the brain and spinal cord).
Schwannomas: tumors that originate in Schwann cells, which surround and insulate nerve fibers.
Ependymomas: tumors that originate in ependymal cells, which line the ventricles of the brain and the central canal of the spinal cord.
Astrocytomas: tumors that originate in astrocytes, a type of glial cell that supports and nourishes neurons.
Metastasis: tumors that have spread from other parts of the body to the spinal cord.
Causes and risk factors of spinal cord tumors
In most cases, the exact cause of spinal cord tumors is unknown. Some spinal cord tumors are associated with inherited genetic syndromes, such as neurofibromatosis type 2 and Von Hippel-Lindau disease. In these cases, tumors can develop as part of a broader set of health problems. However, most spinal cord tumors occur spontaneously, without a clearly identifiable cause. Exposure to certain chemicals or radiation can also increase the risk of developing spinal cord tumors.
Spinal cord tumors, if not detected and treated in time, can lead to a series of complications that impact quality of life. These complications can vary in severity and will depend on the size, location, and type of tumor. Some of the most common complications are:
Chronic pain: persistent pain can significantly affect quality of life.
Muscle weakness: loss of muscle strength can limit mobility and independence.
Loss of feeling: numbness and loss of feeling can make it difficult to perform everyday tasks.
Bowel and bladder problems: incontinence or difficulty urinating can affect quality of life and self-esteem.
Paralysis: in severe cases, spinal cord tumors can cause permanent paralysis.
Sexual dysfunction: spinal cord tumors can affect sexual function.
If you experience any of the symptoms of a spinal cord tumor, it is important to consult a doctor immediately. Early diagnosis and treatment can help prevent serious complications. miento tempranos pueden ayudar a prevenir complicaciones graves.
Diagnosis of spinal cord tumors
The diagnosis of spinal cord tumors is a process that requires a thorough evaluation by a specialized doctor. There is no single test that can confirm the presence of a spinal cord tumor, so different tools and techniques are used to arrive at an accurate diagnosis. The diagnostic process generally involves a combination of tests and procedures. These may include:
Medical history and physical and neurological examination: the doctor will gather information about your symptoms and medical history and will perform an examination to assess your neurological function. This helps identify the possible location and size of the tumor.
Magnetic Resonance Imaging (MRI): MRI is the most important imaging test. It uses magnets and radio waves to create detailed images of the spinal cord, showing the tumor, its size, location, and whether it is compressing the spinal cord or nerves. It also helps differentiate between benign and malignant tumors.
Computerized Tomography (CT scan): CT uses ionizing radiation to create images of the spinal cord and spine. It is useful for evaluating the bone structure of the spine and detecting whether the tumor has affected the vertebrae.
Biopsy: a sample of tissue from the tumor is removed and analyzed in a laboratory. This determines whether the tumor is benign or malignant and what type of cells it is made up of, which is crucial for planning treatment.
Lumbar puncture (cerebrospinal fluid analysis): a sample of the fluid surrounding the brain and spinal cord is obtained to rule out other diseases with similar symptoms, such as infections or inflammation.
Treatment of spinal cord tumors
The treatment of spinal cord tumors is a complex process that requires an individualized, multidisciplinary approach. The treatment of spinal cord tumors depends on the type of tumor, its location, its size, and the patient’s overall health. Treatment options may include:
Surgery: surgery is the main treatment for most spinal cord tumors. The goal of surgery is to remove as much of the tumor as possible without damaging the spinal cord or surrounding nerves.
Radiotherapy: radiotherapy uses high-energy X-rays or other forms of radiation to destroy tumor cells. Radiotherapy can be used after surgery to destroy any remaining tumor cells or to treat tumors that cannot be surgically removed.
Chemotherapy: chemotherapy uses medications to destroy tumor cells. Chemotherapy may be used to treat cancerous tumors that have spread to other parts of the body.
Medications: medications can be used to control the symptoms of spinal cord tumors, such as pain, inflammation, and muscle spasticity.
Rehabilitation: rehabilitation can help patients regain function and independence after treatment for a spinal cord tumor. Rehabilitation may include physical therapy, occupational therapy, and speech therapy.
