Metastatic Spinal Cord Compression

Topic Overview

Summary

Metastatic spinal cord compression (MSCC) is an oncological emergency occurring in 5-10% of cancer patients where spinal metastases compress the spinal cord or cauda equina, causing progressive neurological deficit. [1,2] The classic triad consists of back pain (present in 95% of cases), progressive weakness, and autonomic dysfunction. [3] Without prompt treatment, MSCC leads to irreversible paralysis and loss of sphincter control. The cornerstone of management is immediate high-dose dexamethasone to reduce spinal cord oedema, urgent MRI whole spine within 24 hours, and definitive treatment (radiotherapy or surgery) within 24-48 hours. [4,5] Crucially, ambulatory status at the time of treatment is the strongest predictor of post-treatment ambulatory function—patients who are walking at diagnosis have an 80-90% chance of remaining ambulatory, while those who are paraplegic have only a 10-20% chance of regaining ambulation. [6,7] Early recognition and rapid intervention are therefore critical to preserve neurological function and quality of life.

Key Facts

• Incidence: Overall cumulative incidence of 15.67% in solid tumour patients; 2.84% develop MSCC [1]
• Primary tumours: Lung (20-25%), breast (20%), prostate (15%), myeloma (10%), renal (5-10%) [2,3]
• Presentation: Back pain (95%), leg weakness (75%), sensory changes (50%), bladder/bowel dysfunction (50%) [3,8]
• Key investigation: MRI whole spine with gadolinium within 24 hours (or same-day if neurological deficit present) [4,9]
• Emergency treatment: Dexamethasone 16mg IV/PO STAT, then 8mg BD or 4mg QDS [10,11]
• Definitive treatment: Radiotherapy (most patients) or surgical decompression ± stabilisation (selected patients) [5,12]
• Outcome predictor: Ambulatory status at treatment determines ambulatory status after treatment [6,7,13]

Clinical Pearls

New back pain in a patient with known cancer should prompt immediate consideration of MSCC—it is common, devastating if missed, and time-critical.

Ambulatory status at diagnosis predicts ambulatory status after treatment. The window to preserve walking ability is narrow—act fast.

Give dexamethasone IMMEDIATELY while arranging MRI—it reduces spinal cord oedema and may improve neurological function.

MRI whole spine, not just the symptomatic level—30% of patients have multiple levels of compression.

The absence of weakness does not exclude MSCC—back pain alone in a cancer patient warrants urgent imaging.

Why This Matters Clinically

MSCC represents a race against time. Delay in diagnosis by even hours can mean the difference between a patient walking out of hospital versus requiring a wheelchair for life. Every clinician must maintain a high index of suspicion, know the red flags, and escalate immediately. The median survival after MSCC diagnosis is only 3-6 months, [14] but the quality of those remaining months—whether spent ambulatory and continent versus bedbound and catheterised—depends entirely on rapid recognition and treatment.

Epidemiology

Global Burden

Spinal metastases are the most common malignant lesions affecting the spine, with autopsy studies showing spinal metastases in approximately 30% of cancer patients. [1,15] However, clinical diagnosis occurs in only about 15.67% of solid tumour patients, suggesting significant underdiagnosis. [1] Of patients with spinal metastases, approximately 9.56% (95% CI 5.70-13.42%) will progress to develop MSCC, and another 12.63% (95% CI 7.00-18.25%) will develop pathologic vertebral compression fractures. [1]

Incidence by Region

• United Kingdom: Approximately 4,000 new cases per year [2,4]
• United States: Estimated 25,000-30,000 cases per year
• Global: Incidence rising with increasing cancer survival rates and ageing population

Presenting Feature of Malignancy

MSCC may be the first presentation of cancer in 10-20% of patients. [2,3] These patients often have a more delayed diagnosis due to lack of pre-existing cancer suspicion, highlighting the importance of considering occult malignancy in patients presenting with unexplained back pain and neurological deficit.

Common Primary Tumours

The likelihood of developing MSCC varies significantly by primary tumour type:

Anatomical Distribution

The level of spinal involvement reflects the relative size of each spinal region and local vascularity:

• Thoracic spine: 60-70% (most common—largest vertebral segment, proximity to lung and mediastinal metastases)
• Lumbosacral spine: 20-25%
• Cervical spine: 10% (least common but highest morbidity)
• Multiple levels: 30% of patients have non-contiguous compression at multiple levels [9,16]

Risk Factors for MSCC Development

• Known vertebral metastases: 10-30% will develop MSCC
• Paraspinal mass: Higher risk of epidural extension
• Primary tumour with high bone tropism: Breast, prostate, lung, thyroid, renal
• Advanced stage disease: Multiple bone metastases
• Prior skeletal-related events: Pathologic fractures, bone pain

Pathophysiology

Mechanisms of Spinal Cord Compression

1. Vertebral Body Metastasis (85-90%)

The most common mechanism is haematogenous spread of tumour cells to the vertebral body via Batson's venous plexus—a valveless, low-pressure venous system connecting pelvic, abdominal, and thoracic veins to the vertebral venous plexus. [15] This explains why cancers of the lung, breast, and prostate (draining into this system) frequently metastasise to the spine.

Tumour cells initially seed the vertebral body (particularly the posterior aspect near the pedicles), then grow posteriorly into the epidural space, compressing the thecal sac and spinal cord from an anterior direction.

2. Paravertebral Extension (10-15%)

Some tumours (particularly lymphoma and neuroblastoma) extend through the neural foramen from paravertebral or retroperitoneal masses, causing lateral cord compression.

3. Direct Dural or Intradural Metastasis (less than 5%)

Rare mechanism where tumour cells spread via cerebrospinal fluid (CSF) or haematogenous routes directly to the dura or leptomeninges. More common with melanoma, lung cancer, and breast cancer.

Cascade of Spinal Cord Injury

The pathophysiological progression follows a predictable sequence:

Stage 1: Mechanical Compression

• Tumour mass or bone fragment compresses the spinal cord and nerve roots
• Distortion of normal anatomy

Stage 2: Venous Congestion

• Compression of epidural veins → venous stasis → vasogenic oedema
• Increased pressure within the spinal canal

Stage 3: Arterial Compromise

• Severe compression → arterial insufficiency
• Ischaemia of spinal cord tissue

Stage 4: Cytotoxic Oedema and Infarction

• Cellular swelling, membrane failure
• Irreversible neuronal death if prolonged

Stage 5: Demyelination and Axonal Loss

• Permanent neurological deficit
• Window for recovery lost (typically after 48-72 hours of complete paralysis)

Speed of Onset and Prognosis

The tempo of compression significantly affects prognosis:

• Acute (hours to days): Rapid tumour growth or pathologic fracture—worse prognosis due to inadequate time for venous collateral development
• Subacute (days to weeks): Most common—moderate prognosis
• Chronic (weeks to months): Slow-growing tumours—better prognosis, more time for compensatory mechanisms

Cord Compression vs Cauda Equina Syndrome

The clinical manifestations differ based on anatomical level:

---

Clinical Presentation

Symptom Progression

MSCC typically follows a classic temporal sequence, though progression can vary from hours to months:

Early Phase (Weeks to Months Before Diagnosis)

• Back pain (95% of cases) [3,8]
• Often precedes other symptoms by 6-12 weeks
• May be localised, radicular, or band-like
• Worse at night, worse on lying flat, worse with cough/sneeze/Valsalva

Intermediate Phase (Days to Weeks Before Diagnosis)

• Progressive leg weakness (75%)
• Initially difficulty with stairs, rising from chair
• Progressive to inability to walk
• Sensory changes: numbness, paraesthesia, "tight band" sensation

Late Phase (Hours to Days Before Diagnosis)

• Bladder dysfunction (50%): urinary hesitancy → retention → overflow incontinence
• Bowel dysfunction: constipation → faecal incontinence
• Complete paralysis (if untreated)

Red Flag Symptoms

Pain Characteristics

Localised Spinal Pain

• Tenderness over affected vertebra
• Worse on percussion or palpation
• Mechanical pain worse with movement

Radicular Pain

• Dermatomal distribution corresponding to affected nerve root level
• Shooting, burning, or electric quality
• Bilateral radicular pain suggests midline compression (particularly concerning)
• Often precedes motor weakness

Nocturnal Pain

• Worse at night, disturbing sleep
• May improve with sitting up
• Suggests increased epidural pressure when supine

Neurological Level Determination

Accurate determination of the neurological level of compression is essential for:

1. Correlating symptoms with imaging (confirms diagnosis)
2. Planning surgical approach (cervical vs thoracic vs lumbar)
3. Predicting functional outcome (cervical = quadriplegia, thoracic = paraplegia)
4. Rehabilitation planning (level determines preserved function)

Key Anatomical Principles

Vertebral Level ≠ Spinal Cord Level

The spinal cord terminates as the conus medullaris at approximately L1-L2 vertebral level in adults. Below this, the cauda equina (lumbar and sacral nerve roots) descends within the spinal canal.

Vertebral-Cord Relationship:

• Cervical: Cord segment = vertebral level + 1
  • C5 vertebra → C6 cord segment
• Upper Thoracic (T1-T6): Cord segment = vertebral level + 2
  • T4 vertebra → T6 cord segment
• Lower Thoracic (T7-T9): Cord segment = vertebral level + 3
  • T9 vertebra → T12 cord segment/conus
• T10-T12 vertebrae: Contain conus medullaris and proximal cauda equina
• L1 and below: Only cauda equina (nerve roots, not cord)

Clinical Examination to Determine Level

1. Sensory Level Assessment

Test light touch and pinprick systematically from head to toe to identify the highest intact dermatome. The level of compression is typically 1-2 segments above the sensory level.

Key Landmarks:

• C2: Occipital region
• C3: Supraclavicular area
• C4: Top of shoulder
• C5: Lateral arm
• C6: Thumb
• C7: Middle finger
• C8: Little finger
• T1: Medial forearm
• T4: Nipple line (most reliable thoracic landmark)
• T6: Xiphisternum
• T10: Umbilicus (most reliable abdominal landmark)
• T12: Inguinal ligament/groin
• L1: Inguinal region
• L2: Anterior thigh
• L3: Medial knee
• L4: Medial leg/medial malleolus
• L5: Dorsum of foot/big toe
• S1: Lateral foot/small toe
• S2-S4: Perianal (saddle anaesthesia)

Clinical Pearl: A "sensory level" at the umbilicus (T10) suggests compression at T8-T9 vertebral level. Always image the entire spine as 30% have multiple levels.

2. Motor Level Assessment

Identify the lowest fully functional myotome:

3. Reflex Assessment

Helps differentiate UMN (cord) vs LMN (cauda equina) lesions:

4. Autonomic Assessment

• Bladder: Palpate for distension, measure post-void residual
• Bowel: Digital rectal exam for anal tone (reduced = S2-S4 involvement)
• Perianal sensation: ALWAYS test - loss indicates cauda equina involvement

Correlation with MRI

Once neurological level determined clinically:

1. Predict vertebral level using anatomical relationships above
2. MRI whole spine to confirm and identify:
   • Exact vertebral level(s) of compression
   • Number of levels involved (30% have multiple non-contiguous levels)
   • Degree of canal compromise
   • Cord signal changes (T2 hyperintensity = oedema/ischaemia = poor prognosis)

Discordant Clinical-Radiological Findings

If clinical level does not match MRI findings:

• Multiple levels present: Highest level dominates clinical picture
• Cord oedema extends beyond compression: Clinical level may be higher
• Chronic vs acute: Chronic compression allows reorganization, unpredictable deficits
• Consider alternative diagnoses: Paraneoplastic, leptomeningeal disease, brain metastases

Documentation Example

"Sensory level to pinprick at T10 bilaterally. Motor examination demonstrates MRC grade 3/5 power in hip flexion and knee extension bilaterally, with preserved ankle dorsiflexion (4/5). Hyperreflexia at knees with sustained clonus and bilateral upgoing plantars. Palpable bladder (retention 600ml). Clinical picture consistent with thoracic cord compression at T8-T9 level. MRI whole spine requested urgently."

Ambulatory Status Classification

This is the single most important prognostic factor: [6,7,13]

1. Fully ambulatory: Independent walking without aids
2. Ambulatory with assistance: Requires walking frame, stick, or human support
3. Non-ambulatory (paraparetic): Able to move legs against gravity but cannot walk
4. Non-ambulatory (paraplegic): Complete paralysis, no movement against gravity

Clinical Examination

Systematic Neurological Assessment

General Inspection

• Gait assessment (if ambulatory): wide-based, spastic, or unable
• Posture: kyphosis, scoliosis, or abnormal spinal curvature
• Evidence of weight loss, cachexia

Motor Examination

Power Assessment (MRC Grading)

Test and document power in key muscle groups bilaterally:

MRC Grading

• 0 = No contraction
• 1 = Flicker of contraction
• 2 = Movement with gravity eliminated
• 3 = Movement against gravity
• 4 = Movement against resistance (reduced)
• 5 = Normal power

Tone

• Assess for spasticity (UMN) vs flaccidity (LMN)
• Clonus at ankle (UMN sign)

Sensory Examination

Dermatome Testing

• Light touch and pinprick in all dermatomes
• Identify sensory level (corresponds to compression site)
• Common thoracic levels:
  • "T4: Nipple line"
  • "T6: Xiphisternum"
  • "T10: Umbilicus"
  • "T12: Inguinal ligament"

Perianal Sensation (S2-S4)

• ESSENTIAL to assess—loss indicates cauda equina involvement
• Test with light touch or pinprick

Proprioception and Vibration

• Dorsal column function (may be preserved in anterior cord compression)

Reflex Examination

Clonus

• Sustained rhythmic contractions with rapid dorsiflexion of foot
• Indicates UMN lesion

Autonomic Function

Bladder Assessment

• Urinary retention (palpable bladder, dull to percussion)
• Post-void residual volume (requires catheterisation): > 100ml abnormal, > 200ml significant
• Incontinence (overflow vs true incontinence)

Bowel Function

• Constipation (common)
• Faecal incontinence (late sign)
• Loss of anal tone on digital rectal examination

Spinal Examination

Inspection

• Deformity, asymmetry, or swelling
• Surgical scars

Palpation

• Tenderness on direct palpation of spinous processes
• Percussion tenderness (tap each spinous process with fist)

Range of Motion

• May be limited by pain or spinal instability
• Do NOT force movement if instability suspected

Investigations

Urgent MRI Whole Spine

Gold Standard Investigation [4,9,16]

Indications for MRI

• Any cancer patient with new or worsening back pain
• Any cancer patient with neurological symptoms (weakness, sensory change, bladder dysfunction)
• Known vertebral metastases with change in symptoms

Timing [4]

The urgency of MRI in suspected MSCC is time-critical and directly correlates with functional outcome:

• Within 24 hours: Back pain in cancer patient without neurological deficit

  • "Rationale: Early detection before onset of weakness preserves ambulation in 80-90% [6,7]"
  • Delays beyond 24 hours increase risk of developing irreversible deficit

• Same day (emergency - within 8 hours): Any neurological deficit (weakness, sensory level, bladder/bowel dysfunction)

  • "Rationale: Once weakness begins, neurological deterioration can be rapid and irreversible"
  • Studies show median time from onset of weakness to complete paralysis is 7-14 days without treatment [8]
  • Each hour of delay reduces probability of regaining ambulation

• Within hours (2-4 hours): Rapidly progressive deficit or complete paraplegia less than 48 hours

  • "Rationale: Cord ischaemia becomes irreversible after 48-72 hours of complete compression [13]"
  • This represents the "window of opportunity" for surgical intervention
  • MRI should not delay emergency dexamethasone administration

Evidence for MRI Urgency

A prospective UK audit of 319 MSCC patients demonstrated that diagnostic delays were associated with worse outcomes: [8]

• Median delay from symptom onset to diagnosis: 14 days
• Patients diagnosed within 7 days: 60% ambulatory post-treatment
• Patients diagnosed after 14 days: 35% ambulatory post-treatment (pless than 0.001)

The NICE CG75 guideline emphasizes that MRI timing directly impacts treatment window, as definitive therapy (radiotherapy or surgery) should commence within 24 hours of imaging confirmation. [4] Any delay in imaging therefore compounds treatment delay.

MRI Protocol

• Whole spine: Cervical, thoracic, lumbar, sacral (30% have multiple levels) [9,16]
• Sequences: T1, T2, STIR (short tau inversion recovery)
• Contrast: Gadolinium enhancement (if available) improves sensitivity for leptomeningeal disease and differentiates tumour from oedema
• Sagittal and axial views: To assess degree and level of compression

MRI Findings

• Vertebral body metastases: Low T1, high T2 signal
• Epidural mass: Compressing thecal sac, displacing cord
• Cord signal change: High T2 signal indicates oedema or ischaemia (poor prognostic sign)
• Degree of canal compromise: less than 50%, 50-75%, > 75%, or complete block
• Spinal instability: Vertebral body collapse, pedicle destruction

Contraindications to MRI

• Pacemakers, some metallic implants (check compatibility)
• Severe claustrophobia (may require sedation)
• Inability to lie flat due to pain (analgesia or sedation may be required)

If MRI Unavailable or Contraindicated

• CT myelography: Invasive but can demonstrate cord compression
• CT spine with contrast: Less sensitive for cord compression but can identify bony destruction and epidural masses
• DO NOT delay treatment awaiting transfer for MRI—give dexamethasone and arrange transfer

Plain Radiography

Limited Role

• Low sensitivity for early MSCC (50-60%)
• May show:
  • Vertebral body collapse
  • Pedicle erosion ("winking owl" sign—absent pedicle on AP view)
  • Paraspinal soft tissue mass
  • Lytic or sclerotic lesions

Important: Normal spine X-ray does NOT exclude MSCC—MRI is mandatory if clinical suspicion exists. [4]

Laboratory Investigations

Spinal Stability Assessment

Spinal Instability Neoplastic Score (SINS) [17,28,29]

The SINS framework, developed by the Spine Oncology Study Group, provides a validated, systematic approach to assess spinal stability in cancer patients. This score determines whether a patient requires surgical stabilisation in addition to or instead of radiotherapy.

Why Spinal Stability Matters

Unstable spines are at risk of:

• Pathologic fracture with acute neurological deterioration
• Progressive deformity (kyphosis, scoliosis)
• Intractable mechanical pain
• Failure of radiotherapy alone (radiation does not stabilise)

SINS Scoring System [17]

| Component | Score |\n|-----------|-------|\n| Location | |\n| - Junctional (C0-C2, C7-T2, T11-L1, L5-S1) | 3 |\n| - Mobile spine (C3-C6, L2-L4) | 2 |\n| - Semi-rigid (T3-T10) | 1 |\n| Pain | |\n| - Yes (mechanical pain with movement/loading) | 3 |\n| - Occasional pain (not mechanical) | 1 |\n| - Pain-free lesion | 0 |\n| Bone lesion quality | |\n| - Lytic | 2 |\n| - Mixed (lytic and blastic) | 1 |\n| - Blastic (sclerotic) | 0 |\n| Radiographic spinal alignment | |\n| - Subluxation/translation present | 4 |\n| - De novo deformity (kyphosis, scoliosis) | 2 |\n| - Normal alignment | 0 |\n| Vertebral body collapse | |\n| - > 50% collapse | 3 |\n| - less than 50% collapse | 2 |\n| - No collapse but > 50% body involved | 1 |\n| - None of above | 0 |\n| Posterolateral involvement (facets, pedicles, costovertebral joint) | |\n| - Bilateral | 3 |\n| - Unilateral | 1 |\n| - None | 0 |\n\nInterpretation [17,28]

• 0-6: Stable - Radiotherapy appropriate, no instrumentation needed
• 7-12: Potentially unstable (indeterminate) - Requires surgical opinion and individualized assessment
• 13-18: Unstable - Surgical stabilisation mandatory before or instead of radiotherapy

Validation and Reliability [28,29]

The SINS was validated across multiple specialties (neurosurgery, orthopedic spine surgery, radiation oncology, radiology):

• Inter-observer agreement: Substantial (κ = 0.69-0.79)
• Intra-observer agreement: Almost perfect (κ = 0.84)
• Clinical utility: Changes management in 30-40% of MSCC cases

Fisher et al. (2010) demonstrated that SINS ≥7 identified 95.7% of patients deemed unstable by expert spine surgeons, with high sensitivity (95.7%) and specificity (79.5%). [17]

Clinical Application

All patients with MSCC should have SINS calculated on initial MRI or CT:

1. SINS 0-6: Radiotherapy alone appropriate if radiosensitive tumour
2. SINS 7-12: Urgent spine surgery consultation - may need stabilisation before RT
3. SINS 13-18: Surgery mandatory - do NOT delay for radiotherapy

Important: A patient with SINS ≥13 who receives radiotherapy alone without stabilisation has high risk of fracture progression, worsening deformity, and treatment failure.

Classification & Staging

Bilsky Grading of Epidural Spinal Cord Compression [18]

Clinical Significance

• Grades 1c-3: Definite MSCC requiring urgent treatment
• Grade 2-3: Higher risk of irreversible deficit

Prognostic Scoring Systems

These systems guide treatment decisions (surgery vs radiotherapy vs palliative care):

Tokuhashi Score (Revised) [19]

Interpretation

• 0-8 points: Predicted survival less than 6 months → palliative radiotherapy or conservative
• 9-11 points: Predicted survival 6-12 months → radiotherapy ± limited surgery
• 12-15 points: Predicted survival > 12 months → consider aggressive surgery

Tomita Score [20]

Simpler system based on three factors (each scored 1-4):

1. Growth rate of primary tumour (slow = 1, moderate = 2, rapid = 4)
2. Visceral metastases (none = 0, treatable = 2, untreatable = 4)
3. Bone metastases (solitary = 1, multiple = 2)

Interpretation

• 2-3 points: Long-term survival expected → wide/marginal excision
• 4-5 points: Intermediate prognosis → marginal/intralesional excision
• 6-7 points: Short-term survival → palliative surgery
• 8-10 points: Terminal care → supportive care

Emergency Department Management

Recognition and Triage

High Index of Suspicion Required

MSCC is frequently missed or delayed in the emergency department due to:

• Atypical presentations (back pain without known cancer history)
• Focus on other acute symptoms
• Normal plain radiographs (falsely reassuring)
• Lack of awareness that 10-20% present without known cancer diagnosis [2,3]

Red Flags in Emergency Department [8,27]

Any patient presenting with back pain AND any of the following warrants immediate MSCC assessment:

Triage Category: All suspected MSCC should be triaged as EMERGENCY (equivalent to stroke, STEMI, ruptured AAA)

Time Targets:

• Door to dexamethasone: less than 30 minutes
• Door to MRI: less than 4 hours (if neurological deficit) or less than 24 hours (pain only)
• Door to oncology/neurosurgery consult: less than 6 hours

Initial Assessment in Emergency Department

1. Rapid History (5 minutes)

• Cancer history (type, stage, previous treatments, known metastases)
• Symptom timeline: When did back pain start? When did weakness start?
• Bladder/bowel function: Last void? Able to feel bladder fullness?
• Previous spinal surgery or radiotherapy?

2. Focused Neurological Examination (5 minutes)

Essential components (do NOT delay for full examination):

• Ambulatory status: Can patient walk unaided? Document NOW.
• Power: Hip flexion, knee extension, ankle dorsiflexion (grade 0-5)
• Sensation: Quickly identify sensory level using light touch on trunk
• Reflexes: Knee and ankle jerks (hyperreflexia = UMN, absent = LMN)
• Plantar responses: Babinski sign (upgoing = UMN)
• Perianal sensation: ALWAYS check - critical for cauda equina
• Anal tone: Digital rectal exam if time permits

3. Immediate Interventions (Parallel Processing)

Do these simultaneously (mobilise entire team):

Pharmacological:

• ✅ Dexamethasone 16mg PO or IV STAT (give BEFORE imaging) [4,10,26]
• ✅ Analgesia: IV morphine 2.5-5mg or oral morphine 10-20mg
• ✅ PPI: Omeprazole 20mg IV or PO (gastric protection)
• ✅ Anti-emetic: Ondansetron 4mg IV if nausea

Supportive:

• ✅ Catheterisation if urinary retention (measure residual volume)
• ✅ Nil by mouth (may need emergency surgery)
• ✅ IV access: Large bore cannula (may need IV contrast, fluids, anaesthesia)

Investigations:

• ✅ Emergency MRI whole spine: Request immediately (state "?MSCC" clearly)
• ✅ Bloods: FBC, U&E, LFT, bone profile, coagulation, group & save
• ✅ ECG: Pre-anaesthetic assessment if surgery likely

Referrals:

• ✅ Oncology: Contact immediately (may already be under their care)
• ✅ Spinal surgery: Neurosurgery or orthopaedic spine (discuss urgency)
• ✅ Clinical oncology: Radiotherapy planning (if RT candidate)

4. Communication with MRI Department

When requesting emergency MRI, provide:

• ✅ "Suspected MSCC in patient with [cancer type]"
• ✅ Degree of urgency: "Emergency same-day" vs "Within 24 hours"
• ✅ Contact number for results

5. Documentation

Critical elements to document (medicolegal importance):

Time-stamped documentation:

• Time of symptom onset (back pain, weakness, bladder dysfunction)
• Ambulatory status at presentation (walking independently/with aid/not walking)
• Power grades in key muscle groups (MRC 0-5 scale)
• Sensory level (if present)
• Time dexamethasone administered
• Time MRI requested and performed
• Time specialist consulted

Example Documentation:

Exam: Alert, cooperative. T8 sensory level to light touch. Power: hip flexion 4/5, knee extension 3/5, ankle DF 4/5 bilaterally. Hyperreflexia knees and ankles, sustained clonus, bilateral upgoing plantars. Palpable bladder 500ml post-void residual. Perianal sensation reduced.

13:05 - Dexamethasone 16mg PO given, omeprazole 20mg PO
13:10 - Morphine 10mg PO, catheterised (drained 600ml)
13:15 - Emergency MRI whole spine requested (confirmed slot 15:00)
13:20 - Oncology contacted (SpR to review), neurosurgery contacted (discussed with reg)
13:25 - NBM, bloods sent, IV access secured

Diagnosis: Suspected metastatic spinal cord compression (MSCC) - EMERGENCY
Plan: Emergency MRI → MDT discussion → definitive treatment within 24h"

Common Emergency Department Pitfalls

❌ PITFALL 1: "Back pain is musculoskeletal, give NSAIDs and discharge"

Mistake: Attributing cancer patient's back pain to mechanical causes without imaging.

Consequence: Delayed diagnosis, patient deteriorates at home, presents paraplegic.

Solution: ANY back pain in cancer patient = urgent imaging. [4]

---

❌ PITFALL 2: "X-ray spine is normal, so can't be MSCC"

Mistake: Relying on plain radiographs to exclude MSCC.

Consequence: 40-50% of MSCC have normal plain films. [4]

Solution: MRI is ONLY acceptable imaging for MSCC. Never rely on X-rays.

---

❌ PITFALL 3: "Waiting for MRI before giving steroids"

Mistake: Delaying dexamethasone until imaging confirms diagnosis.

Consequence: Every hour of untreated cord oedema worsens ischaemia and reduces recovery potential.

Solution: Give dexamethasone at point of clinical suspicion (BEFORE MRI). [4,10]

---

❌ PITFALL 4: "Patient has widespread metastases, so MSCC not treatable"

Mistake: Nihilism about treatment based on advanced cancer stage.

Consequence: Failure to offer treatment that preserves walking and continence in remaining life.

Solution: Even palliative patients benefit from preserving mobility. RT can be delivered in 1 session (8Gy). [21]

---

❌ PITFALL 5: "Imaging lumbar spine only because leg weakness"

Mistake: Targeted imaging of symptomatic region only.

Consequence: 30% have multiple non-contiguous levels - cervical or thoracic compression missed. [9,16]

Solution: ALWAYS image WHOLE SPINE (cervical, thoracic, lumbar, sacral). [4,9]

---

❌ PITFALL 6: "Admitted to general medical ward, MRI booked for tomorrow"

Mistake: Treating as routine admission rather than emergency.

Consequence: 24-hour delay to imaging, further delay to treatment, worse outcomes.

Solution: MRI same-day if any neurological deficit, direct admission to oncology/neurosurgical unit. [4]

---

Immediate Emergency Management

The moment MSCC is suspected clinically, initiate the following actions before imaging:

1. Dexamethasone [10,11,26,27]

Dosing Controversy and Evidence

Corticosteroids are universally recommended in MSCC to reduce vasogenic oedema, but optimal dosing remains debated:

High-Dose Protocol (16mg)

• Loading dose: 16mg IV or PO STAT
• Maintenance: 8mg BD or 4mg QDS
• Evidence: Sorensen et al. (1994) RCT comparing 96mg vs no steroids showed improved ambulation (81% vs 63%, p=0.05) [10]
• Rationale: Maximises anti-oedema effect in acute emergency setting
• UK standard: Recommended by NICE CG75 as 16mg loading dose [4]

Moderate-Dose Protocol (10mg)

• Loading dose: 10mg IV or PO STAT
• Maintenance: 4mg QDS
• Evidence: Some centres use lower doses to reduce side effects while maintaining efficacy
• Rationale: Reduced hyperglycaemia, gastric irritation, and delirium in frail/elderly patients

Key Evidence - Cochrane Review (2015) [11]

George et al. systematic review of corticosteroid trials found:

• Improved ambulation: Steroids vs no steroids improved walking ability (RR 1.30, 95% CI 1.00-1.69)
• Dose comparison: Limited evidence comparing high vs moderate dose - no significant difference detected
• Quality of evidence: Low to moderate due to small RCTs with heterogeneous populations

Current Consensus [4,26,27]

• Give dexamethasone immediately at clinical suspicion (before imaging confirmation)
• Dose: 16mg STAT is UK standard; 10mg acceptable if concerns about side effects
• Route: IV or PO (bioavailability similar, PO acceptable if patient can swallow)
• Timing: Every minute counts - give at first suspicion, not after imaging
• Duration: Continue until definitive treatment (RT or surgery), then rapid taper over 5-7 days
• Co-prescribe: PPI (omeprazole 20mg OD) for gastric protection mandatory

Clinical Pearl: Dexamethasone may produce transient neurological improvement within 24-48 hours by reducing cord oedema, even before definitive treatment. This does NOT mean the patient can defer imaging or treatment.

2. Analgesia

• MSCC pain is often severe and neuropathic
• Immediate: IV morphine 2.5-5mg or oral morphine 10-20mg
• Regular: Opioids (morphine, oxycodone, fentanyl patches)
• Adjuvant: Gabapentin or pregabalin for neuropathic pain
• Avoid NSAIDs if surgery planned (bleeding risk)

3. Bladder Management

• If urinary retention: Catheterise immediately (reduces bladder distension and autonomic dysreflexia risk)
• Measure post-void residual if uncertain
• Monitor fluid balance

4. VTE Prophylaxis

• Patients with MSCC are high risk for DVT/PE due to immobility and malignancy
• Mechanical: TED stockings, intermittent pneumatic compression
• Pharmacological: LMWH (unless contraindicated by planned surgery or bleeding risk)

5. Pressure Area Care

• High risk of pressure sores if immobile
• Regular turning, pressure-relieving mattress
• Involve tissue viability nurses

6. Mobilisation Restrictions

• If spinal instability suspected (SINS ≥7): strict bed rest, neutral spine alignment, consider spinal collar or brace
• If stable: encourage gentle mobilisation (improves venous return, reduces VTE risk)

Urgent MRI and MDT Discussion

Within 24 Hours of Presentation [4]

• MRI whole spine (see Investigations section)
• Results discussed urgently with multidisciplinary team (MDT):
  • Oncologist
  • Spinal surgeon (neurosurgery or orthopaedic spine)
  • Clinical oncologist (radiotherapy)
  • Palliative care
  • Radiology

Definitive Treatment Options

Treatment selection based on:

1. Prognosis (Tokuhashi/Tomita score)
2. Radiosensitivity of primary tumour
3. Number and extent of spinal lesions
4. Spinal stability
5. Neurological status and rate of deterioration
6. Patient performance status and wishes

---

Radiotherapy

Indications [12,21]

• Most common definitive treatment for MSCC (> 70% of patients)
• Radiosensitive tumours: myeloma, lymphoma, prostate, breast, small cell lung
• Multiple levels of compression (surgery impractical)
• Poor surgical candidates (low performance status, short life expectancy)
• No spinal instability

Regimens

• Single fraction: 8 Gy × 1 (common for poor prognosis, equivalent efficacy to fractionated) [21]
• Fractionated: 20 Gy in 5 fractions (5 days) or 30 Gy in 10 fractions (2 weeks)
• Stereotactic radiosurgery (SRS): High-dose, precision radiotherapy for oligometastatic disease (16-24 Gy in 1-2 fractions) [22]

Timing

• Ideally within 24 hours of diagnosis [4]
• Delay > 48 hours associated with worse outcomes

Outcomes [12,21]

• Ambulatory patients: 60-70% remain ambulatory
• Non-ambulatory: 10-30% regain ambulation
• Pain relief: 50-70% achieve significant pain reduction

Side Effects

• Acute: Fatigue, nausea, skin reaction, transient worsening (oedema)
• Late: Radiation myelitis (less than 5%, usually with doses > 50 Gy), vertebral compression fracture

---

Surgical Decompression

Indications [5,12,23,30]

Absolute Indications

• Spinal instability (SINS ≥13) - requires stabilisation regardless of radiosensitivity
• Radioresistant tumour (renal cell carcinoma, melanoma, sarcoma, hepatocellular carcinoma)
• Previous radiotherapy to maximal spinal tolerance (re-irradiation limited)
• Rapid neurological deterioration despite radiotherapy
• Tissue diagnosis required (unknown primary with no other biopsy site)
• Bone fragment causing compression (retropulsed bone from pathologic fracture)
• Spinal deformity causing mechanical pain or progressive kyphosis

Relative Indications - Patchell Criteria [5]

• Good prognosis (expected survival > 3-6 months, Tokuhashi ≥9)
• Single level compression (surgery practical)
• Ambulatory or paraparetic less than 48 hours (window for recovery)
• Good performance status (able to tolerate surgery)
• No significant medical comorbidities (fit for anaesthesia)

Surgery vs Radiotherapy: The Evidence [5,30,31]

Landmark Trial: Patchell et al., Lancet 2005 [5]

This pivotal RCT randomized 101 MSCC patients to direct decompressive surgery + postoperative radiotherapy vs radiotherapy alone:

Inclusion Criteria:

• Single area of compression
• Paraparesis or paraplegia less than 48 hours
• Expected survival > 3 months
• Histologically confirmed cancer

Results:

Trial Stopped Early: Independent data monitoring committee stopped trial early due to clear superiority of surgery arm.

Key Findings:

• Surgery doubled the chance of remaining/regaining ambulation (84% vs 57%)
• Benefit greatest in non-ambulatory patients: 62% regained walking vs 19% with RT alone
• Patients in surgery group remained ambulatory 10x longer (122 days vs 13 days)
• Functional independence (ambulation, continence) dramatically better with surgery
• Survival similar (not a survival benefit, but quality-of-life benefit)

Criticisms and Limitations:

• Single level compression only (does not apply to multilevel MSCC)
• Excluded very poor prognosis patients
• Highly selected population (only 1-10% of MSCC patients meet criteria)
• Surgery performed at expert centres with spinal surgeons

Real-World Application [30,31]

Subsequent observational studies have confirmed Patchell's findings in broader populations:

• Quraishi et al. (2013): 10-year experience of 199 MSCC surgeries showed 76% ambulatory post-op, median survival 9.8 months [30]
• Meta-analyses confirm surgery superior for selected patients but emphasize importance of patient selection [31]

When NOT to Operate [5,23]

Surgery is NOT beneficial and may cause harm in:

• Very poor prognosis: Tokuhashi score 0-5, expected survival less than 3 months
• Complete paralysis > 48-72 hours: Irreversible cord damage, very low chance of recovery (less than 10%)
• Multilevel compression: Surgery impractical for > 2 non-contiguous levels
• Severe medical comorbidities: ASA grade 4-5, cardiac/respiratory failure
• Patient preference: Comfort-focused care, declining surgery

Surgery vs Stereotactic Radiosurgery (SRS) [22,32]

Emerging evidence suggests SRS may bridge the gap between conventional RT and surgery:

• Higher local control: 80-90% with SRS vs 60-70% with conventional RT [22]
• Potential surgery alternative: For radioresistant tumours with minimal cord compression
• Ongoing trials: Comparing SRS to surgery in selected populations [32]
• Current role: Oligometastatic disease, radiosurgical spine tumour (SINS less than 7, no instability)

Decision-Making Framework: Surgery vs Radiotherapy

START: MSCC confirmed on MRI
↓
ASSESS STABILITY (SINS score)
├─ SINS ≥13 (Unstable) → SURGERY (stabilisation mandatory)
├─ SINS 7-12 (Indeterminate) → Surgical consult + assess other factors
└─ SINS 0-6 (Stable) → Assess tumour radiosensitivity
    ↓
    ASSESS RADIOSENSITIVITY
    ├─ Radioresistant (RCC, melanoma, sarcoma) → Consider SURGERY or SRS
    └─ Radiosensitive (myeloma, lymphoma, breast, prostate, SCLC) → Assess prognosis
        ↓
        ASSESS PROGNOSIS (Tokuhashi score)
        ├─ Good (≥9, survival > 6 months) + Single level + Ambulatory or paretic less than 48h + Fit → SURGERY + RT
        ├─ Intermediate (6-8) or multilevel → RADIOTHERAPY
        └─ Poor (≤5, survival less than 3 months) or paralysed > 72h → PALLIATIVE RT or supportive care

Surgical Techniques

Landmark Trial: Patchell et al. 2005 [5]

This randomised controlled trial compared surgery + radiotherapy vs radiotherapy alone in 101 patients:

• Primary outcome: Ambulatory at 30 days post-treatment
  • "Surgery + RT: 84% remained/regained ambulation"
  • "RT alone: 57% remained/regained ambulation (p=0.001)"
• Secondary outcomes: Surgery group had longer retention of ambulation (122 days vs 13 days), better bladder/bowel function, reduced opioid requirements
• Survival: No difference in overall survival (126 days vs 100 days, p=0.033 but not clinically significant)

Outcomes [5,12,23]

• Ambulatory pre-op: 85-95% remain ambulatory
• Paraparetic pre-op: 60-70% regain ambulation
• Paraplegic > 48h: less than 10% regain ambulation

Surgical Complications

• Wound infection (5-10%)
• CSF leak (3-5%)
• Worsening neurology (1-3%)
• Hardware failure (5-10% long-term)
• Medical complications: DVT/PE, pneumonia, MI

Post-Operative Radiotherapy

• Typically delivered 2-4 weeks post-surgery (once wound healed)
• Improves local control and prevents recurrence

---

Conservative/Palliative Management

Indications

• Very poor prognosis (Tokuhashi score 0-5, expected survival less than 3 months)
• Complete paralysis > 72 hours (very unlikely to recover)
• Patient preference for comfort-focused care
• Severe medical comorbidities precluding surgery/radiotherapy

Supportive Care Measures

• Continue dexamethasone (symptom control, reduce oedema)
• Optimise analgesia (opioids, neuropathic agents)
• Physiotherapy and occupational therapy
• Wheelchair assessment and mobility aids
• Catheter care (long-term catheter or intermittent self-catheterisation if feasible)
• Bowel management (laxatives, suppositories, manual evacuation)
• Psychological support for patient and family
• Palliative care involvement

---

Multidisciplinary Team (MDT) Involvement

Core MDT Members

• Oncologist: Cancer-directed therapy, prognosis assessment
• Spinal surgeon: Neurosurgeon or orthopaedic spine surgeon for surgical candidacy
• Clinical oncologist: Radiotherapy planning and delivery
• Radiologist: MRI interpretation, interventional radiology (vertebroplasty/kyphoplasty)
• Palliative care: Symptom management, end-of-life planning
• Physiotherapist: Mobility assessment, rehabilitation
• Occupational therapist: ADL support, equipment provision
• Specialist nurse: Coordination, patient education

MDT Decision-Making

For each patient, the MDT must rapidly answer:

1. What is the prognosis? (Tokuhashi/Tomita score)
2. Is the tumour radiosensitive or radioresistant?
3. Is the spine stable or unstable? (SINS score)
4. Is the patient ambulatory? For how long have they been non-ambulatory?
5. Are there multiple levels or a single level?
6. What is the patient's performance status and fitness for surgery?
7. What are the patient's goals and preferences?

Treatment Algorithm

MSCC Suspected
↓
IMMEDIATE: Dexamethasone 16mg, analgesia, catheterise if retention
↓
URGENT: MRI whole spine within 24h (or same day if deficit)
↓
MDT Discussion
↓
├─ Good prognosis (Tokuhashi ≥9) + Single level + Ambulatory/recently non-ambulatory + Fit for surgery
│  → SURGERY (decompression ± stabilisation) → Post-op radiotherapy
│
├─ Radiosensitive tumour + Stable spine + Multiple levels or poor surgical candidate
│  → RADIOTHERAPY (within 24h)
│
├─ Radioresistant tumour + Stable spine + Poor surgical candidate
│  → RADIOTHERAPY (lower expectation) or PALLIATION
│
└─ Poor prognosis (Tokuhashi less than 6) + Paralysed > 72h + Poor performance status
   → PALLIATIVE CARE (steroids, analgesia, supportive)

---

• Late: Hardware failure, pseudoarthrosis, adjacent segment degeneration

---

Prognosis & Outcomes

Functional Outcome: The Critical Determinant

Ambulatory Status at Treatment Predicts Post-Treatment Status [6,7,13]

This is the most consistent finding across all studies:

Key Message: Every hour counts. The transition from ambulatory to non-ambulatory is often irreversible. Early recognition and treatment are paramount.

Factors Associated with Better Functional Outcome

Positive Prognostic Factors

• Ambulatory at diagnosis [6,7,13]
• Slow progression of symptoms (> 14 days from onset to treatment)
• Radiosensitive primary tumour (myeloma, lymphoma, prostate, breast)
• Single level of compression
• No cord signal change on MRI (absence of T2 hyperintensity)
• Good performance status (KPS ≥70%)
• Younger age (less than 60 years)
• Surgical decompression (vs radiotherapy alone in selected patients) [5]

Negative Prognostic Factors

• Non-ambulatory at diagnosis [13]
• Rapid progression (less than 48 hours)
• Complete paralysis > 48-72 hours
• Radioresistant tumour (melanoma, renal, sarcoma)
• Cord signal change on MRI (T2 hyperintensity = oedema/ischaemia)
• Poor performance status (KPS less than 50%)
• Multiple levels of compression
• Visceral metastases

Survival

Median Overall Survival Post-MSCC: 3-6 months [14]

Survival varies significantly by primary tumour:

Important: Survival is determined by cancer biology, not MSCC itself. However, functional independence (ambulation, continence) profoundly impacts quality of remaining life.

Quality of Life

MSCC dramatically reduces quality of life if neurological function is lost:

• Loss of mobility → dependence, loss of dignity
• Incontinence → social isolation, skin breakdown
• Chronic pain → reduced participation in valued activities
• Psychological distress → depression, anxiety, existential suffering

Recent QOL studies demonstrate that patients who retain ambulation have significantly better emotional wellbeing, social functioning, and overall QOL compared to wheelchair-bound patients, even with similar survival times. [24]

Patient & Family Information

What is Metastatic Spinal Cord Compression?

Metastatic spinal cord compression (MSCC) happens when cancer that has spread to the bones of the spine grows and presses on the spinal cord—the main nerve bundle that carries signals from your brain to the rest of your body. This pressure can damage the nerves and cause weakness, numbness, and problems with bladder or bowel control.

MSCC is a medical emergency. Quick treatment can prevent permanent paralysis and preserve your ability to walk and care for yourself.

Warning Signs – When to Seek Urgent Help

If you have cancer (or have had cancer in the past), watch for these symptoms and contact your cancer team immediately:

Red Flag Symptoms

• New or worsening back pain (especially pain that wakes you at night)
• Weakness in your legs or difficulty walking
• Numbness or tingling in your legs, feet, or around your bottom
• Difficulty passing urine or losing control of your bladder
• Difficulty with bowel movements or losing control of your bowels

Do not wait—these symptoms can progress rapidly. Contact:

• Your oncology team or specialist nurse
• Your GP (request urgent same-day assessment)
• Emergency Department if unable to reach cancer team

What Tests Will I Need?

• MRI scan of your whole spine: This is the most important test. It shows where the cancer is pressing on the spinal cord. You'll need this scan urgently (usually the same day or within 24 hours).
• Blood tests: To check your general health and plan treatment.

What Treatments Are Available?

Treatment aims to relieve pressure on the spinal cord and preserve your ability to walk.

1. Steroids (Dexamethasone)

• Given immediately (often before the MRI scan)
• Reduces swelling around the spinal cord
• Can improve weakness and pain

2. Radiotherapy

• High-energy X-rays targeted at the cancer pressing on the spine
• Most common treatment for MSCC
• Usually given over 1-10 sessions

3. Surgery

• Operation to remove the tumour pressing on the spinal cord and stabilise the spine
• Considered if the cancer is resistant to radiotherapy, if the spine is unstable, or if you're fit enough for surgery

4. Supportive Care

• Pain relief (strong painkillers if needed)
• Physiotherapy to help with movement and strength
• Occupational therapy to help with daily tasks
• Bladder and bowel management if needed
• Emotional and psychological support

What Can I Expect?

If treated quickly (while still able to walk):

• 8 out of 10 people remain able to walk after treatment
• Pain usually improves
• Quality of life can be maintained

If weakness has already developed:

• Some people regain the ability to walk, but recovery is less certain
• Rehabilitation and support can help you adapt and maintain independence

Important: The earlier MSCC is diagnosed and treated, the better the outcome. This is why recognising warning signs and seeking help immediately is so crucial.

Living with MSCC

• Mobility: Physiotherapy, walking aids, wheelchairs if needed
• Bladder care: Catheters, pads, or intermittent self-catheterisation
• Pain management: Regular painkillers, nerve pain medications
• Emotional support: Cancer support services, counselling, peer support groups
• Practical support: Occupational therapy, home adaptations, carers

Questions to Ask Your Medical Team

• What is my prognosis?
• What treatment options do I have?
• What are the benefits and risks of each treatment?
• Will I be able to walk after treatment?
• What support is available for me and my family?
• Who can I contact if my symptoms worsen?
