National Institute of Clinical Excellence guidelines on Metastatic Spinal Cord Compression recommend urgent consideration of patients with spinal metastases and imaging evidence of structural spinal failure with spinal instability for surgery to stabilise the spine and prevent Metastatic Spinal Cord Compression. We aimed to compare neurological outcomes of patients managed operatively and non-operatively. Prospective collection of 397 patients' data over a 4-year period.

Males represented 59.2% of patients. Median age was 69 years. Non-operative intervention in 62.2% of patients. Prostate, lung, Breast, Myeloma, Renal Cell Carcinoma and Lymphoma accounted for over 75% of all primary tumours (n=305). Median Length of hospital stay was longer in the operative group of 15 days compared to 10 days in the non-operative group (p<0.0001). Patients who were ambulating on presentation maintained their ambulation in 70.2% of cases in the operative group compared to 90.9% in the non-operative group (p<0.0001). However, upon discharge 41% of patients managed operatively were ambulatory compared to the non-operative group rate of 36.5% (p<0.0001). In Prostate, Breast, Myeloma, RCC and Lymphoma 100% of patients managed non-operatively maintained ambulation. Lung primaries managed operatively had an 80% chance of maintaining ambulation compared to 76.9% in the non-operative group (p<0.05)

A higher proportion of patients managed non-operatively maintained ambulation than those managed operatively. With operative intervention, more patients regained ambulatory status. Whilst we have mainly focused on ambulatory status in this paper there are other factors to consider including pain relief and spinal stability which may be an indication for surgical intervention.
