Spinal cord compression in Palliative Care

Spinal cord compression (SCC) is a medical emergency in which the spinal cord is compressed by an external mass, leading to neurological symptoms that can rapidly progress to permanent paralysis if not treated urgently.

In palliative care, SCC is one of the most feared emergencies because:

• It can steal a patient's remaining independence in hours or days.
• It causes severe, unrelenting pain.
• It leads to paralysis, loss of bladder and bowel control, and pressure sores.
• It transforms a mobile patient into a bedridden, fully dependent person.
• The window for effective treatment is narrow — permanent damage occurs if treatment is delayed.

SCC is frequently observed in advanced carcinoma, particularly:

In Uganda: Breast cancer, prostate cancer, and lymphoma are common causes. Kaposi's sarcoma and lymphoma related to HIV/AIDS can also cause SCC.

Important: In 20% of cases, compression occurs at more than one level simultaneously. Always suspect multiple sites if symptoms are widespread or confusing.

The cauda equina (Latin for "horse's tail") is the bundle of nerve roots that continues below the end of the spinal cord. Compression here causes:

• Saddle anesthesia (numbness in the area that would touch a saddle)
• Bladder and bowel dysfunction (urinary retention, incontinence, constipation)
• Leg weakness (often asymmetrical)
• Reduced reflexes

Prognostic note: Recovery is more likely after cauda equina lesions than after true spinal cord compression, because peripheral nerves regenerate better than spinal cord tissue.

SCC follows a predictable pattern if untreated:

BACK PAIN ➔ WEAKNESS ➔ SENSORY LOSS ➔ BLADDER/BOWEL DYSFUNCTION ➔ PARALYSIS

The earlier the intervention, the better the outcome. Once paralysis and loss of sphincter control occur, recovery is unlikely.

Back pain occurs in more than 90% of cases. It is typically the first symptom and the one that should raise suspicion.

Other pain descriptions:

• Sharp shooting pains down the legs
• Electric shock-like sensations (Lhermitte's sign) — indicates nerve irritation
• Unpleasant sensation below the level of compression — numbness, tingling, or "dead" feeling

Any patient with advanced cancer and the following should be treated as SCC until proven otherwise:

Nursing implication: Do not wait for X-ray results to start treatment if clinical suspicion is high. Begin steroids and analgesia immediately.

In Uganda: MRI is available only in major referral hospitals (Mulago, Mbarara, etc.) and is expensive. Many patients cannot access it. Clinical judgment must guide treatment.

Nursing implication: If advanced imaging is unavailable (as is common in rural Uganda), do not delay treatment. Start steroids and analgesia based on clinical suspicion.

Nursing implication: Be honest with the patient and family about prognosis. Creating false hope leads to frustration, expense (paying for futile physiotherapy), and damaged trust when recovery does not occur.

SCC requires urgent, coordinated management involving steroids, analgesia, and definitive treatment (radiotherapy or surgery).

Purpose: To reduce inflammation and edema (swelling) around the tumor and spinal cord, thereby relieving pressure and potentially improving neurological function.

Why dexamethasone?

• Potent anti-inflammatory effect reduces peri-tumoral edema.
• May improve leg weakness within hours to days.
• "Buys time" before radiotherapy or surgery can be arranged.

Nursing actions for steroid administration:

• Give with food or antacids to protect the stomach (steroids cause gastric irritation).
• Monitor for side effects: hyperglycemia (high blood sugar), mood changes, insomnia, increased appetite, oral thrush.
• In HIV/AIDS patients, consider adding fluconazole prophylaxis for fungal infections (steroids increase risk of opportunistic infections).

SCC causes severe pain that requires aggressive management.

Nursing tip: A patient who was comfortable on 10mg morphine every 4 hours may need 20mg, 30mg, or more as the compression worsens. Do not be afraid to increase rapidly under medical direction.

Nursing role:

• Arrange urgent referral.
• Explain to family what radiotherapy involves and why it is needed urgently.
• Support the patient during transport and treatment.

Before starting definitive cancer treatment, rule out infections that can mimic or complicate SCC:

Nursing implication: If the patient has fever, night sweats, weight loss, or known TB exposure, mention this to the doctor. A simple TB test may change the entire treatment plan.

Once the acute emergency is addressed, meticulous nursing care prevents complications and maintains dignity.

Immobility from SCC creates high risk for pressure sores (bedsores), which can become infected and cause further suffering.

Teach family members to turn the patient, check the skin, and report any redness or breakdown immediately.

SCC is devastating. A patient who was walking yesterday may never walk again.

Why honesty matters:

• Families may spend money they don't have on futile physiotherapy.
• Patients may blame themselves for "not trying hard enough" when recovery is impossible.
• Trust is damaged if the patient realizes they were not told the truth.

• Back pain (escalating, >90% of cases)
• Affected legs (heavy, weak, uncoordinated)
• Coughing/sneezing worsens pain
• Known cancer (advanced stage)
• Pain band-like (tight belt sensation)
• Area of numbness below a level
• Incontinence (urinary or bowel)
• Neurological signs (reduced reflexes, decreased tone)

"Thoracic is Top, Lumbar is Low, Cervical is Least"

• Thoracic: 70% (Top frequency)
• Lumbar: 20% (Low frequency)
• Cervical: 10% (Least frequent)

• Steroids (Dexamethasone 16-24mg immediately)
• Titrate analgesia (morphine increase)
• Educate family
• Radiotherapy (urgent referral, within 24 hours)
• Assess neurological status
• Dexa taper if response good
• Catheterize if retention
• Assess pressure areas
• Rehabilitation (realistic goals)
• Explain prognosis honestly

"WALK-WIN, SPHINCTER-LOSE"

• If patient can WALK ➔ WIN (good prognosis)
• If SPHINCTER lost ➔ LOSE (poor prognosis)

• Define spinal cord compression and explain why it is a palliative care emergency.
• List the two main causes of SCC and their percentages (85-90% vertebral metastases, 10% paravertebral masses).
• Name the cancers most commonly associated with SCC (breast, lung, prostate, kidney, lymphoma, myeloma, sarcoma).
• Describe the anatomical distribution of compression (70% thoracic, 20% lumbar, 10% cervical).
• Explain the difference between spinal cord compression and cauda equina compression (below L2).
• Describe the classic progression of symptoms in SCC (pain ➔ weakness ➔ sensory loss ➔ bladder/bowel dysfunction ➔ paralysis).
• List the characteristics of pain in SCC (bony, radicular, band-like, worsened by coughing/sneezing).
• Explain why escalating back pain + heavy legs is sufficient to treat for SCC.
• Describe the physical examination findings in SCC (tenderness, weakness, sensory level, decreased reflexes, decreased rectal tone).
• Discuss investigations — what plain X-ray shows, why normal X-ray doesn't rule out SCC, and what MRI is the gold standard.
• State the single most important prognostic indicator (neurological status before treatment).
• Explain why loss of sphincter function is a bad prognostic sign.
• Describe the immediate management — dexamethasone dose, route, and why it is given urgently.
• Explain the role of radiotherapy — timing, field, and urgency.
• Discuss nursing care — bladder care, bowel care, pressure area prevention, family education.
• Explain why honest communication about prognosis is essential and give examples of what to say in different situations.
• Address the challenges of managing SCC in Uganda — availability of radiotherapy, cost, transport, rural access.

• Clinical guidelines for the management of Spinal Cord Compression in Palliative Care.
