Metastatic spinal cord compression: Incidence, epidemiology and prognostic factors.

Background: Metastatic spinal cord compression (MSCC) is a severe complication in patients with cancer, and its incidence rate is difficult to accurately estimate. The aim of this study is to report the incidence and epidemiological and prognostic characteristics of MSCC in patients with cancer.

Material And Methods: We analysed a cohort of 1736 patients diagnosed with cancer of any origin who were hospitalised in a palliative care unit. We collected epidemiological data, signs and symptoms, mean time to diagnosis, treatment regimen, response to treatment and mortality for the patients diagnosed with MSCC.

Results: In the 1736 patients, we identified 28 (1.6%) cases of MSCC. The average age was 67.2 (SD, 12.7) years, and lung cancer was the most common primary tumour (42.8%). The thoracic spine was the most affected location (12 cases, 42.8%), and pain was the predominant symptom (13 cases, 46.4%). The median survival after the MSCC diagnosis was 84.5 days.

Conclusions: We observed an incidence rate of 1.6% (N=28) for MSCC in a cohort of 1736 patients with cancer. MSCC is a marker of poor prognosis, with a mean survival of less than 3 months from diagnosis and a hospital mortality of 32.4%.
