| Abstract: | OBJECTIVE: Surgery plays an important role in achieving local tumor control and cure for primary and metastatic tumors of the spine. As has been established with regard to sarcomas at extraspinal sites, these goals may best be achieved by en bloc resection with negative histological margins. Unfortunately, sarcomas of the spine often present with tumor patterns that are amenable only to intralesional resection, if neurological preservation is a priority. This study is a retrospective analysis of the long-term outcomes of patients who had operations for sarcomas of the spine using modern surgical approaches, intralesional resections, and spinal instrumentation. METHODS: Between 1985 and 1997, 59 patients had spinal operations for sarcoma involving the extrasacral spine. Data regarding tumor histology, grade, surgical indications, patterns of spinal tumor involvement, and neurological and functional outcomes were reviewed at presentation and at tumor recurrence. RESULTS: Thirty-five patients underwent a single operation, and 24 patients required reoperation for locally recurrent tumors. At presentation, only nine patients (15%) had tumors that were amenable to marginal or wide resections. Functional outcomes after initial spinal surgery and after operations performed at first tumor recurrence showed that 95% of patients had maintained or regained ambulation. Intradural extension of tumor was seen in 5 of 12 patients who had three or more operations for locally recurrent disease. The median survival from first spine operation was 18 months, and the median event-free interval between the first and second spine operations was 13 months. CONCLUSION: Surgery for sarcoma of the spine is useful for maintaining or improving neurological and functional outcomes, but local tumor recurrences are common. Because of the anatomy of the tumor at presentation and concern for neurological preservation, few patients are candidates for marginal or wide resections. |
