Understanding Spinal Cord Tumors,
from diagnosis to care
Spinal cord tumors encompass a diverse group of neoplasms arising within or adjacent to the spinal cord. Treatment requires specialized expertise to balance tumor control with neurological preservation.
New Spinal Cord Tumor Cases/Year (U.S.)
Diagnosis combines imaging, pathology, and molecular features to guide care.
Most plans combine surgery, radiation, systemic therapy, and ongoing supportive care.
What is spinal cord tumors, and how is it classified?
The subtypes below summarise how this condition is classified in modern neuro-oncology — each behaves differently and is treated differently.
Intramedullary Astrocytoma
Most common intramedullary tumor in children. Low-grade (pilocytic, diffuse) and high-grade variants. Infiltrative growth limits resection.
Intramedullary Ependymoma
Most common intramedullary tumor in adults. Well-circumscribed, amenable to GTR. Myxopapillary variant at conus/filum.
Hemangioblastoma
Highly vascular intramedullary tumor. ~25% associated with VHL syndrome. Curable with surgery when complete resection achieved.
Intradural-Extramedullary
Meningiomas and schwannomas most common. Well-circumscribed, surgically curable. Meningiomas predominantly in women.
Chordoma
Arises from notochordal remnants. Sacral most common, also clival and mobile spine. Brachyury-positive. Proton therapy important.
Extradural Tumors
Most are metastatic. Primary vertebral tumors rare (chondrosarcoma, osteosarcoma, Ewing sarcoma). Epidural compression is emergency.
The biomarkers that define your tumor
Modern classification depends on specific molecular markers — each revealing something different about the tumor and its likely behaviour.
Defines diffuse midline glioma including spinal cord. Poor prognosis. WHO Grade 4 regardless of histology.
Diffuse midlineMutations found in some spinal astrocytomas. IDH-mutant tumors have better prognosis than IDH-wildtype.
AstrocytomaNuclear expression is pathognomonic for chordoma. Essential diagnostic marker. Potential therapeutic target.
Chordoma definingGermline mutations cause VHL syndrome: hemangioblastomas, clear cell RCC, pheochromocytoma. Lifelong surveillance.
HemangioblastomaHomozygous deletion in spinal ependymoma associated with higher grade and worse prognosis.
Ependymoma prognosticDot-like perinuclear staining pattern in ependymoma. Helps distinguish from astrocytoma.
Ependymoma markerHow spinal cord tumors can present
Symptoms vary by tumor location and size. This is general information — only your care team can interpret your situation.
Pain
Localized back/neck pain, often worse at night or with recumbency. Radicular pain following nerve root distribution.
Motor Weakness
Progressive weakness below tumor level. May be asymmetric. Upper motor neuron signs (spasticity, hyperreflexia).
Sensory Changes
Numbness, paresthesias, proprioceptive loss. Cape-like sensory loss in intramedullary tumors (central cord pattern).
Bowel/Bladder Dysfunction
Late symptom indicating significant cord compression. Urinary retention or incontinence, constipation.
Gait Abnormality
Ataxic or spastic gait depending on tumor location. Progressive difficulty walking is common presentation.
Brown-Sequard Syndrome
Ipsilateral motor weakness and proprioceptive loss with contralateral pain/temperature loss. Classic but rare.
Treatment options for Spinal Cord Tumors
Treatment depends on tumor type, grade, location, and overall health. Most plans combine several approaches.
Microsurgery
Primary treatment for most spinal cord tumors. GTR when safely achievable. Intraoperative neurophysiology monitoring (MEP/SSEP) is mandatory.
Radiation Therapy
Adjuvant for incompletely resected tumors. Proton therapy preferred for chordoma. IMRT for spinal ependymoma/astrocytoma.
Observation
For small, asymptomatic, or stable tumors. Serial MRI monitoring. Appropriate for some low-grade tumors with stable neurology.
Stereotactic Radiosurgery
CyberKnife for small, well-defined spinal tumors. Single or hypofractionated treatment. Limited by cord tolerance.
Chemotherapy
Limited role. Temozolomide for high-grade astrocytoma/H3K27M. Imatinib investigated for chordoma.
Clinical Trials
Targeted therapies, immunotherapy, and novel radiation approaches under investigation.
Your multidisciplinary care team
Care is delivered by a team — specialists who diagnose and treat, and those who protect day-to-day quality of life.
Neurosurgeon
Performs brain or spine surgery for tumor removal or biopsy.
Best for: resection strategy, biopsy decisions, and surgery-related risk.
Neuro-oncologist
Brain-tumor specialist who leads treatment planning.
Best for: integrating pathology, imaging, medication, and trial options into one plan.
Radiation oncologist
Plans and delivers precision radiation therapy.
Best for: dose planning, side effects, and timing around surgery or systemic therapy.
Nurse navigator
Guides you through appointments, insurance, and logistics.
Best for: referrals, scheduling, records, and getting the right people in the room.
Oncology nurse
Day-to-day care coordination and symptom management.
Best for: new symptoms, medication questions, and urgent care coordination.
Mental health
Psychological support for patients and caregivers.
Best for: coping with uncertainty, caregiver strain, and adjustment after diagnosis.
