ABSTRACT Objective: The goal of the study was to report the prevalence of spinal metastasis with unknown primary tumor, clinical features, treatment results and patient survival. Methods: A retrospective evaluation of 103 patients with spinal metastasis and epidural compression, who underwent surgical treatment between March 2009 and August 2015. The prevalence of metastatic spinal tumor with unknown primary tumor was evaluated, as well clinical features, survival and treatment results. Results: Of 103 patients with spinal metastasis and epidural compression, seven patients (6.8%) with unknown primary tumor site were identified; five (71.4%) male and two (28.6%) female, with ages ranging from 37 to 67 years (50.7 years). The metastasis was located in the thoracic spine in six of the patients (85.7%) and in the cervical spine in one (14.3%). The mean survival time was 44.8 days. Conclusion: Spinal metastasis with unknown primary tumor was found in 6.8% of patients. The prognosis and outcomes were poor, and patients had poor survival rates. Level of evidence III; Experimental study.
