The Elderly Patient with a Metastatic Spinal Cord Compression
A 68-year-old woman with known metastatic breast cancer (bone and liver) presents with 5 days of progressive leg weakness, now unable to walk unaided, and new urinary hesitancy. MRI shows a T7 vertebral body metastasis with epidural extension causing moderate cord compression, plus a pathological fracture with kyphosis. She has a prognosis of perhaps 6–12 months, is on bisphosphonates, and has had prior chest wall radiotherapy. She is on dexamethasone 16 mg/day started in the emergency department. Her performance status is ECOG 2.
1. How do you decide between surgery, radiotherapy, and supportive care, and what is the immediate management?

Immediate management. This is metastatic spinal cord compression (MSCC) - a true oncological emergency. Confirm dexamethasone dose (16 mg/day is standard, often as 16 mg then 16 mg/day, with gastric protection and glucose monitoring). Urgent discussion with clinical oncology and spinal surgery. Analgesia, thromboprophylaxis (with caution), bladder care, and pressure-area care.
Decision framework. The classic decision tool is the Tokuhashi or Tomita score, but the more useful modern framework is the NICE/Patchell-style approach: consider (1) prognosis, (2) mechanical stability (Spine Instability Neoplastic Score - SINS), (3) degree of cord compression and radiosensitivity, (4) performance status, and (5) patient preference.
- Surgery is favoured when there is mechanical instability, a single level of compression, radioresistant tumour, or rapid neurologic decline, and when prognosis exceeds ~3 months and performance status allows. Posterior decompression and stabilisation (or vertebrectomy and reconstruction) can restore stability and ambulation.
- Radiotherapy alone is appropriate for radiosensitive tumours, multiple levels, poor performance status, or short prognosis. Single-fraction or short-course RT is reasonable.
- Supportive care is appropriate when prognosis is very short, the patient is bedbound, or she declines intervention.
Given her ECOG 2, 6–12 month prognosis, mechanical instability (pathological fracture with kyphosis) and prior chest wall RT (limiting further RT dose), surgery plus post-operative RT is a reasonable option - but this must be a shared decision. If she is frail or declines, RT alone is defensible. The exam wants a reasoned, individualised answer, not a formula.
2. She asks, 'Will I walk again?' How do you answer, and what rehabilitation and safety issues must you address?
Read the worked answer
Answering honestly. Give a realistic, hopeful but non-false answer: ambulation depends on the degree of pre-treatment deficit, the speed of decompression, and tumour biology. Patients who are ambulatory at treatment have a much better chance of remaining so; those already unable to walk have a lower but non-zero chance of regaining function. Avoid guaranteeing recovery. Emphasise that early treatment gives the best chance and that rehabilitation starts immediately.
Rehabilitation. Early physiotherapy, occupational therapy, and involvement of palliative care alongside active treatment (not instead of it). Address spasticity, pain, bladder and bowel management, and VTE prophylaxis. A specialist spinal injuries/rehab team improves outcomes.
Safety. (1) Pressure ulcer prevention - she is at high risk. (2) Falls prevention and moving/handling. (3) Bone health - bisphosphonates, calcium/vitamin D, and caution with any further bony procedures. (4) Cord compression can progress - teach her and her family red-flag symptoms and ensure rapid re-access. (5) Psychological support and discussion of goals of care.
Communication. Use clear language, check understanding, involve family, and document the discussion. The exam is testing whether you can combine technical judgement with honest, compassionate communication.
