Spinal cord tumor

Disease Description (Causes and Symptoms)

• Definition summary: Tumors that arise in the spinal cord or the nerves adjacent to the spinal cord, or that have metastasized to the spinal cord. Depending on their location, they are classified as extradural, intradural (extra-/intradural), or intramedullary tumors. They include primary tumors (such as schwannomas, meningiomas, and astrocytomas) and metastatic tumors.
• Causes/pathophysiology: The cause is unknown in most cases, but some are associated with hereditary conditions (e.g., neurofibromatosis). When a tumor directly invades nerve tissue or compresses surrounding structures, nerve transmission in the spinal cord is disrupted. Neurological function may also decline due to the tumor, surrounding edema, and impaired blood flow.
• Main symptoms: Gradually or acutely worsening back pain (low back pain and radiating pain), sensory abnormalities (tingling and decreased sensation), muscle weakness and movement disorders, difficulty walking, bowel and bladder dysfunction (urination and defecation problems), and localized tenderness. The pattern and rate of symptom development vary depending on the tumor’s location and growth rate.

Treatment Methods and Precautions

• Diagnostic basics: A neurological examination (sensation, muscle strength, and reflexes) and MRI (including contrast) are standard imaging tests. CT and X-ray, PET (when metastasis is suspected), and tissue examination (biopsy/surgery) are used for pathological confirmation.
• Surgery: When possible, the goal is complete removal of the tumor (total resection). If the risk of nerve damage is high, partial resection (decompression) may be performed to relieve symptoms, followed by additional treatment. The surgical method depends on the location of the lesion and its pathological type.
• Radiation therapy: Used when surgery is not possible, for residual lesions after surgery, or for radiation-sensitive tumors (e.g., metastatic lesions). Stereotactic radiosurgery (SRS/SBRT) is used for localized high-dose treatment.
• Chemotherapy: Effective for some malignant tumors in children and systemic malignant diseases (such as lymphoma). Its effectiveness may be limited in some spinal cord tumors in adults. When there is spread through the cerebrospinal fluid, chemotherapy administered into the cerebrospinal fluid may also be considered.
• Steroids: Reduce edema caused by spinal cord compression and help improve symptoms quickly (used as an emergency treatment).
• Conservative and supportive treatment: Pain management (analgesics and medications for neuropathic pain), bladder and bowel management, rehabilitation therapy (physical and occupational therapy), and psychosocial support and rehabilitation planning.
• Multidisciplinary approach: Collaboration among neurosurgery, radiation oncology, medical oncology, rehabilitation medicine, and other specialties is necessary.
• Precautions (including self-care): If acute neurological deterioration occurs (such as acute paralysis or inability to urinate or defecate), visit the emergency room immediately. When taking steroids, monitor for infection, gastrointestinal symptoms, elevated blood glucose, and other effects. Before and after radiation or chemotherapy, monitor for common complications such as infection, fatigue, and reduced blood cell counts.

Outpatient Visit Checklist (Including Preparation Items and Example Questions)

• Items to prepare/bring:
  • A list of currently used medications (including doses and administration times)
  • Records of allergies and previous adverse drug reactions
  • Previous test results and imaging materials (MRI/CT/PET; if possible, a CD/DVD or radiology report)
  • Medical and surgical history (especially a history of cancer) and pathology results (if available)
  • The time symptoms began and how they have progressed (a symptom checklist or diary)
  • Records of bladder and bowel status (frequency, incontinence, etc.)
  • Mobility aids (walker, cane) if used
  • Insurance information and identification; a caregiver or family member (if assistance is needed with decisions)
• Key items the healthcare team will check during the outpatient visit:
  • When symptoms began and how quickly they have changed (acute vs. gradual)
  • The location, nature, and triggers of pain (posture, coughing, etc.)
  • Sensory abnormalities (distribution and type), changes in muscle strength, and whether difficulty walking is present
  • A history of cancer and systemic symptoms (weight loss, fever, etc.)

Examples of General Questions to Ask the Doctor

• What is the exact pathology of this disease (tissue examination result)? How does it affect the treatment direction?
• Which treatment is recommended among surgery, radiation, and chemotherapy, and what is the goal of each (cure vs. symptom relief)?
• What side effects and complications can be expected, and how can they be prevented and managed?
• What is the expected timing and plan for rehabilitation and returning to daily activities (walking and returning to work)?

Examples of Disease-Specific Questions

• Based on the location and imaging findings of my lesion, can it be completely removed surgically? If complete removal is not possible, what additional treatment will be needed?
• To what extent is recovery of my current neurological function (especially urination and walking) possible, and what degree of improvement can be expected through rehabilitation?

(Note: Treatment and prognosis vary greatly depending on the tumor’s pathological type, location, size, the patient’s overall condition, and response to treatment. Please consult your healthcare team for an accurate diagnosis and treatment plan.)
