Abstract
INTRODUCTION: Primary spinal cord tumors are rare tumors that are usually heterogeneous having variable histopathological subtypes. Rapidly, growing space-occupying lesions in the spinal canal cause severe loss of function. This study aimed to analyze all adult patients diagnosed with primary spinal cord tumors and to describe their location, symptoms, histopathological types, surgical outcome, complications, recurrence in a single institution, and prognostic factors. MATERIALS AND METHODS: The study was a retrospective study of 178 patients with spinal tumor who underwent surgical intervention at the department of neurosurgery at a tertiary care institute from 2014 to 2021. Patient demographic characteristics, symptoms, radiological features, spinal level of tumor, spinal compartment, preoperative and postoperative McCormick grade, and complications were recorded, and a comparison of outcomes after surgical intervention was done. RESULTS: In our study, 97 patients were males and the rest of the 81 patients were females. The mean age at the time of surgery was 43.5 years. The thoracic region of the spinal canal was the most involved with 67 (37.64%) cases, whereas intradural extramedullary was the most common (65.73%). Schwannoma was the most common histopathological subtype (46.06%). Total excision was achieved in 154 cases. A total of 37 patients were in Grades 4 and 5 of modified McCormick's grade preoperatively. However, postoperatively, there were only 17 patients in this group. Two patients with cervical intramedullary tumor expired in the postoperative period. CONCLUSION: Early surgical intervention with sound microneurosurgical skills gives good outcomes independent of the type and location of tumor. Better outcomes are seen in extradural tumors, early surgical intervention, tumors better amenable to total resection, and in patients with better preoperative neurological status.
