Scope of this summary
Adults with known or possible cancer and new severe or progressive spinal pain, radicular pain, weakness, sensory change, gait impairment or bladder or bowel dysfunction. This is an oncologic emergency pathway; nonmalignant compression, traumatic injury and pediatric disease require their corresponding protocols.
The Bottom Line
- Suspect metastatic epidural compression before paralysis: progressive nocturnal or movement-related spinal pain, radicular pain, gait change, limb weakness, a sensory level or sphincter dysfunction warrants immediate emergency and oncology action.
- Perform and document a focused neurologic examination. ACR rates MRI of the spine area of interest without and with contrast as usually appropriate for acute or progressive myelopathy; CT myelography may be appropriate when MRI cannot be performed.
- Start corticosteroid treatment promptly when neurologic compression is suspected or confirmed under the local oncology protocol, while addressing glucose, infection, gastrointestinal and psychiatric risks and not delaying imaging or definitive care.
- Engage spine surgery, radiation oncology and medical oncology immediately. ASTRO recommends surgery plus dexamethasone and radiation over radiation alone for appropriate patients with cord or cauda-equina compression.
- Choose surgery, conventional radiation or stereotactic treatment from neurologic status, mechanical stability, radiosensitivity, prior radiation, disease burden, performance, prognosis and the patient鈥檚 goals鈥攏ot from histology alone.
Practical clinical workflow
1
Record cancer type and status, pain site and mechanical features, exact neurologic onset, ambulation, bladder and bowel function, prior spine surgery or radiation, systemic treatment and goals of care.
2
Immobilize or position according to pain and suspected instability, provide analgesia, keep the patient fasting when surgery is plausible and arrange emergency transfer to a center with MRI and definitive capability.
3
Document motor power, reflexes, sensation, level, gait when safe, perianal sensation and sphincter findings; do not rely on urinary retention alone or wait for a complete syndrome.
4
Obtain urgent MRI of the region indicated by the neurologic level and specialist or radiology assessment, initiate the agreed corticosteroid pathway and assess mechanical instability with the spine team; communicate the images directly rather than waiting for routine clinic review.
5
Deliver definitive decompression and/or radiation, then coordinate thrombosis prevention, bladder and bowel care, rehabilitation, pressure protection, bone and systemic cancer treatment and advance-care planning.
Safety boundaries and escalation
- Do not send a patient with progressive weakness, saddle sensory change or sphincter dysfunction to routine outpatient imaging; irreversible loss of walking and continence is time-dependent.
- Systemic anticancer therapy, bisphosphonates or analgesia alone do not promptly decompress the cord and must not substitute for local emergency treatment.
- High spinal instability, retropulsed bone or rapidly progressive deficit requires urgent surgical judgment before movement or radiation-only planning.
- Corticosteroid adverse effects are real, but suspected neurologic compression needs a protocolized decision rather than omission or unsupervised prolonged therapy.
Localization
US emergency practice combines ACR myelopathy imaging with local spine-oncology capability and ASTRO treatment guidance. These sources do not create a universal whole-spine imaging rule, steroid dose or radiation fractionation for every patient; those choices require the current protocol and specialist plan.
