Abstract

Medical and surgical advances allow surgical treatment of many patients with spinal metastases. Although emerging surgical techniques facilitate stabilization of the collapsed spine, surgical candidates should be carefully selected. However, the lack of confirmed criteria to determine survival of these patients makes selection for surgery difficult. Clinical symptoms have been considered possible factors associated with prognosis, but their relevance has not been confirmed because of inadequate power for proper statistical analysis. We retrospectively reviewed 165 patients who had surgery for spinal metastases from various cancers. Clinical symptoms including pain, paresis, and walking status were recorded. Multivariate analysis indicated that the histologic type of the primary tumor was the strongest prognostic factor, followed by preoperative paresis and pain. Myeloma, thyroid cancer, renal cell cancer, breast cancer, and prostate cancer had better prognoses than other kinds of cancer. Patients without paresis before surgery had a better prognosis than patients with paresis, and patients with no pain before surgery had a better prognosis than those with pain. Preoperative walking status was not an independent prognostic factor.
