The role of laminectomy in the combined treatment of metastatic spinal cord compression.
A retrospective analysis of clinical data concerning 140 patients with spinal cord compression is presented. Treatment consisted of a surgical decompressive laminectomy followed by radiation therapy in 127 cases. Primary radiation therapy supported by steroids was applied in only 26 cases. A dose of 30-40 Gy in 15-20 fractions was delivered to all patients. Treatment outcome was analyzed by comparing motor function (categories: no deficit, mild deficit ambulatory, paraparetic not ambulatory, paraplegic), sphincter function, and pain relief before and after treatment in both modalities. Following laminectomy and radiation therapy, 82% of paraparetic patients regained their ability to walk, sphincter function improved in 68%, pain relief was achieved in 88%. Following radiation therapy alone, 64% of paraparetic patients became ambulatory, 33% showed a normalization of sphincter function, and 72% became pain free. Our results indicate that laminectomy should play a major role in the treatment of patients with metastatic spinal cord compression. The decision as to the treatment of choice has to be made individually for each patient taking into consideration his general condition, life expectancy, and origin of the primary.
