About Ependymoma

Overview

Ependymoma is a rare type of tumor that can occur in the brain or spinal cord. It originates from the ependymal cells, which line the central nervous system. These tumors are typically soft in texture and may have a gray or red color. Ependymomas can be found in both children and adults, although they are more common in children. They can be classified into different grades based on their characteristics: Grade 1 tumors are slow-growing and noncancerous, Grade 2 tumors are low-grade and may occur in the brain or spine, and Grade 3 tumors are malignant and fast-growing. Treatment for ependymoma often involves surgical removal of the tumor followed by radiation therapy to target any remaining cancer cells.

Causes and Risk Factors

Ependymomas are caused by certain changes to genes that control the way our cells function. These gene mutations can increase the growth and spread of cancer cells. However, the exact cause of ependymomas is not known.

Non-modifiable risk factors include:

• Age: Ependymomas can affect individuals of any age, but they are most common in children under the age of 4.
• Genetic predispositions: Certain genetic abnormalities, such as chromosome 22 abnormalities, familial adenomatous polyposis, and neurofibromatosis type 2 (NF2), may slightly increase the risk of anaplastic ependymoma tumors.

There is limited information about modifiable risk factors specific to ependymomas. However, maintaining a healthy lifestyle, including regular physical activity and a balanced diet, is generally recommended for overall health and well-being.

It's important to note that these risk factors may not directly cause ependymomas but could potentially contribute to an increased risk. Regular check-ups with a healthcare professional can help monitor any potential risks or concerns.

Symptoms

The most common early symptoms of ependymoma include:

• Headaches, often experienced upon waking up in the morning
• Neck pain
• Vision changes, such as blurred vision or vision loss
• Jerky eye movements
• Nausea and vomiting, especially in the morning
• Difficulty with balance or walking
• Seizures and convulsions
• Tingling, numbness, or weakness in the limbs

As ependymoma progresses or reaches higher severity, additional symptoms may occur, such as:

• Increased head size in infants (caused by hydrocephalus)
• Backaches and soreness
• Tingling and weakness in the legs
• Problems with sexual, urinary, or bowel function

It's important to report persistent symptoms to a doctor for proper screening and diagnosis. Remember to consult with a healthcare professional about any symptoms you may be experiencing.

Diagnosis

To diagnose Ependymoma, the following examinations, tests, and procedures are commonly performed:

• Physical exam and health history: The healthcare provider examines the body for signs of disease and takes a detailed history of the patient's health habits, past illnesses, and treatments.
• MRI (Magnetic Resonance Imaging): This non-invasive imaging procedure uses a magnetic field and radiofrequencies to create detailed images of the brain or affected organ. It provides high soft-tissue contrast, making it the primary method for diagnosing Ependymoma.
• CT (Computed Tomography) scan: A specialized X-ray that produces cross-sectional images of the brain. It provides more detailed slices than standard X-rays and can offer better calcification information.
• Biopsy: An invasive test where a small portion of tissue is surgically removed or obtained with a needle. The tissue is then studied in a lab to determine if it is cancerous.
• Lumbar puncture (spinal tap): Invasive procedure where a sample of spinal fluid is withdrawn using a needle. This helps determine if cancer cells are present in the nervous system.

To determine the stage or severity of ependymoma, additional examinations, tests, and procedures may include:

• Neurological exam: A series of questions and tests to assess brain, spinal cord, and nerve function. This includes assessing mental status, coordination, walking ability, muscle strength, senses, and reflexes.
• MRI with gadolinium: This procedure involves injecting a contrast agent called gadolinium into a vein before performing an MRI. Gadolinium enhances the images and helps evaluate the extent of tumor involvement.

It's important to consult with your healthcare professional for personalized advice on which examinations, tests, and procedures are appropriate for your individual situation.

Treatment Options

The goals of treatment for ependymoma are to remove as much of the tumor as possible, determine the tumor type, and minimize symptoms. The following are the different treatment options and how they work to achieve these goals:

• Surgery: This is the primary treatment. Its goal is to obtain tissue for tumor typing and remove as much of the tumor as possible without causing additional symptoms. Surgeons may use techniques like intraoperative neurophysiological monitoring and neuronavigation to maximize resection while preserving neurological function.
• Radiation therapy: If surgery cannot remove the entire tumor or if the cancer has spread, radiation therapy may be used. Highly targeted radiation beams can shrink the tumor without harming surrounding tissues.
• Chemotherapy: Chemotherapy medications may be used before surgery to shrink the tumor or in cases where surgery and radiation are not sufficient. However, evidence supporting its effectiveness in improving survival rates is lacking.
• Clinical trials: Participating in clinical trials can provide access to new chemotherapy, targeted therapy, or immunotherapy drugs that may be effective in treating Ependymoma. These trials aim to explore novel treatment approaches.

Specific treatment recommendations depend on factors such as age, remaining tumor after surgery, tumor type, and tumor location. It's important to note that treatment plans should be individualized, and it's crucial to consult with a healthcare professional for medication dosing and potential side effect information.
