Spinal Cord Compression from Epidural Metastases

EPIDURAL spinal cord compression from metastases is among the most dreaded complications of cancer; it occurs in 5 percent of patients who die of cancer 1 2 3 (approximately 20,000 patients a year in the United States). If untreated, metastatic epidural compression inexorably progresses, causing paralysis, sensory loss, and sphincter incontinence.
