Synopsis
Detect malignant spinal pain before loss of walking or sphincter function, activate the MSCC pathway and coordinate steroid, imaging, stability and definitive oncological treatment.
- Metastatic epidural disease most often spreads from a vertebral metastasis, causing collapse, instability and compression; prostate, breast, lung, kidney, thyroid and myeloma are important sources.
- Pain is commonly the earliest feature: severe unremitting, progressive, night, mechanical or cough-and-strain pain, local tenderness or radicular pain in a person with cancer warrants urgent action.
- Weakness, gait disturbance, limb numbness, a sensory level and bladder or bowel dysfunction indicate established neural compromise and should be reported as MSCC immediately.
- NICE recommends whole-spine MRI within 24 hours for suspected MSCC, locally where possible; multiple non-contiguous vertebral lesions are common enough that one painful level is insufficient coverage.
- Start dexamethasone 16 mg orally or an equivalent parenteral dose as soon as possible for neurological symptoms or signs, continuing 16 mg daily while surgery or radiotherapy is awaited.
- If imaging rules out MSCC, stop dexamethasone unless another indication exists, tapering rather than stopping abruptly when clinically required after sustained exposure.
- Immobilise without delay when neurological signs suggest instability, and consider it for moderate or severe movement-related pain; seek expert stability assessment within 24 hours to minimise unnecessary bed rest.
- Definitive treatment is individualised surgery, radiotherapy or both, based on stability, neurological status, tumour biology, radiosensitivity, prognosis, prior treatment and patient goals.
- Preserved mobility at treatment predicts function, so patients with suspicious pain but no deficit still need urgent cancer-team advice and MRI within one week for suspected spinal metastases.
- Analgesia, thrombosis and pressure prevention, bladder and bowel care, rehabilitation, bone treatment, systemic anticancer planning and palliative support start alongside compression treatment.
Key red flags
A patient with cancer develops severe progressive, unremitting or nocturnal spinal pain, pain worse on movement, coughing or straining, focal tenderness or new radicular pain before objective weakness appears.
Gait becomes heavy or unsteady, legs weaken, reflexes become brisk, an extensor plantar or truncal sensory level appears and bladder or bowel control changes.
Lumbar metastasis produces bilateral or progressive radicular symptoms, saddle sensory change, lower-motor-neurone weakness and impaired urinary flow sensation or retention.
Pain is markedly provoked by sitting, standing, turning or loading and relieved by lying, sometimes with collapse or deformity, indicating movement-related risk while transfer is planned.
Constitutional symptoms, focal spinal pain and cord signs may be the first presentation of cancer; emergency compression care continues while a tissue and staging strategy is developed.
Investigation priorities
Confirm level and degree of neural compression, cord signal, epidural mass and additional vertebral metastases for treatment planning.
Management branches
Cancer is known or suspected and new weakness, gait, sensory or sphincter dysfunction suggests compression.
- Contact the designated MSCC service immediately, perform a timed neurological and stability assessment and immobilise when neurological signs or movement pain suggest instability.
- Start dexamethasone 16 mg orally or equivalent parenterally as soon as possible unless contraindicated, add glucose and gastric monitoring and arrange whole-spine MRI within 24 hours.
- Discuss imaging the same day with spinal surgery and oncology to choose decompression and stabilisation, urgent radiotherapy or a tumour-specific option and to avoid sequential referral delay.
- Continue pressure, thrombosis, bladder, bowel, analgesia, communication and rehabilitation care throughout transfer and definitive treatment.
