METASTATIC SPINAL TUMOURS IN A DISTRICT GENERAL HOSPITAL

Abstract

Treatment regimes for malignant disease have improved significantly in recent years leading to improved survival after diagnosis of primary and Metastatic disease. Against this background we have reviewed the activity in a district general hospital offering a spinal service to evaluate the efficacy of surgery in metastatic disease. Materials and Methods: Retrospective casenote review of patients identified through theatre records over a 3 year period. 27 patients were identified as having surgery for spinal tumours, of whom 24 were for metastatic disease. All presented with pain and/or signs of acute cord compression and had an intervention on an urgent or emergency basis by one of three spinal surgeons. Results: Of the 24 patients with metastases, the primary tumours were breast (7), lung(7), prostate(2), renal(2), bladder(1), clear cell (1), colon(1), thyroid(1) and unknown (2). The operations performed were: spinal decompression or vertebrectomy and stabilisation(18), stabilisation without decompression(4), decompression alone (1), biopsy only (1). Mean survival after surgery was 9.4 months (range 0–42 months) with a poorer outcome in those with pulmonary and renal disease. 7 patients remain alive with a mean follow up of 21 months. Symptomatic improvement was recorded in 19 / 24 patients in terms of pain control and/or restoration of function. There were 4 perioperative deaths of which none were due to complications of surgery.

Discussion: Patients with terminal diseases are challenging to treat as they require multidisciplinary input both in hospital and in the community. Good results can be achieved for both symptom control and pain relief by surgical intervention for spinal metastases if appropriate early referral is made to a spinal surgeon. We have found that with the general improvements in survival with malignancy an aggressive surgical regime of decompression or vertebrectomy with spinal stabilisation can be supported.
