Metastatic Spinal Cord Compression (MSCC)

Metastatic spinal cord compression is compression of the spinal cord or cauda equina by malignant disease and an oncological emergency; progressive spinal pain, gait change, weakness, sensory loss or bladder/bowel symptoms in someone with current or previous cancer need immediate MSCC-pathway escalation.

In a nutshell

MSCC is an oncological emergency: current or previous cancer plus progressive spinal pain, gait change, weakness, sensory loss or bladder/bowel dysfunction needs immediate MSCC-coordinator contact. Give dexamethasone promptly when neurological symptoms or signs are present, obtain whole-spine MRI within 24 hours, and move quickly to surgery or urgent radiotherapy according to fitness, instability and prognosis.

Classic presentation

A person with prostate or breast cancer develops progressive thoracic or mechanical back pain, then leg weakness, a sensory level and urinary retention. Escalation begins before the deficit becomes fixed.

Key points

  • Think MSCC with current or previous cancer plus progressive or severe back pain, radicular pain, gait change, weakness, sensory loss or bladder/bowel symptoms.
  • Immediately contact the MSCC coordinator and treat suspected cord or cauda equina compression as an oncological emergency.
  • Give dexamethasone promptly for neurological symptoms or signs; do not routinely give steroids to people without neurological involvement.
  • MRI the whole spine as soon as possible and always within 24 hours; plain X-ray does not rule out MSCC.
  • Immobilise when neurological signs suggest instability or when movement causes moderate to severe pain, then obtain early stability advice.
  • Offer surgery as soon as possible when suitable; offer radiotherapy within 24 hours when surgery is unsuitable, using NICE's dose and prognosis criteria.
  • The neurological examination, ability to walk, pain, instability, prognosis and goals guide treatment; a time limit after paraplegia alone should not exclude surgery.
  • Plan rehabilitation, bladder/bowel care, pressure and VTE prevention, cancer treatment, palliative care and discharge support from admission.

First-line investigation

Urgent whole-spine MRI with neurological and bladder/bowel assessment; use CT if MRI is contraindicated and do not rely on plain radiography.

Management

Activate the emergency pathway

  • Immediately contact the MSCC coordinator for cancer plus cord/cauda equina symptoms or signs; assess neurology, bladder/bowel function, pain and instability.1

Give conditional steroids and immobilise safely

  • Give dexamethasone promptly for neurological symptoms or signs and immobilise without delay when instability is suspected or movement-related pain is moderate to severe.1,2

Obtain whole-spine MRI

  • Arrange whole-spine MRI as soon as possible and within 24 hours, using CT only when MRI is contraindicated; plain radiography cannot exclude MSCC.1

Preserve function and prevent complications

  • Provide analgesia, bladder/bowel and pressure care, VTE prevention, equipment and rehabilitation, and mobilise only through a stability-informed graded plan.1,2

Deliver surgery or urgent radiotherapy

  • Offer surgery promptly when suitable; otherwise offer urgent radiotherapy within 24 hours when indicated, following NICE's criteria for prognosis, prior paralysis and fractionation.1

Coordinate cancer and long-term care

  • Continue rehabilitation, systemic cancer and bone-directed care, palliative support, discharge planning, equipment and advance care planning according to the person's goals.1

Exam traps

  • Do not wait for paralysis: pain, gait change, radicular symptoms or subtle weakness can be the treatable window.
  • Do not image only the painful level; metastases are often multiple, so MRI the whole spine.
  • Do not immobilise everyone indefinitely; follow NICE's instability and movement-pain criteria and seek early stability advice.
  • Do not give routine corticosteroids to every person with spinal metastases without neurological symptoms or signs.
  • Do not use plain X-ray to rule out MSCC, and do not delay emergency treatment for biopsy when neurological deterioration is present.
  • Surgery and radiotherapy are not mutually exclusive; postoperative radiotherapy and supportive rehabilitation may still be required.
