Abstract
STUDY DESIGN: Retrospective cohort study. PURPOSE: To explore the complications and risk factors for total resection (TR) of primary thoracic and lumbar spinal tumors over the past decade at our institution. METHODS: Patients meeting inclusion criteria (primary spinal tumors, thoracic or lumbar location, TR at our center) were included. Demographic characteristics, surgical data, perioperative complications and management results were reviewed. Patients were stratified by tumor site, the number of excised segments, and recurrence status to elucidate distinctive characteristics. RESULTS: The cohort comprised 103 patients, with a mean age of 35.8 years. On average, 1.83 vertebral segments were resected per patient. Perioperative complications were substantial, totaling 166 events, with 71 classified as major and 95 as minor, yielding an average of 1.61 complications per patient. No perioperative deaths occurred, but 79 patients (76.7%) experienced at least one complication. Multiple vertebral sections correlated with a higher complication rate (P = 0.031), and lumbar surgeries exhibited elevated risks of large vascular injury (P = 0.001), neurological deterioration, and cerebrospinal fluid leakage compared to thoracic cases. Conversely, thoracic spinal procedures showed a higher rate of pleural effusion (P = 0.004). Binary logistics stepwise regression identified multi-segmental resection as the independent risk factor for major perioperative complications. CONCLUSIONS: TR of primary spinal tumors is associated with a high perioperative complication rate, although most events have a favorable prognosis. Complication characteristics vary based on the surgical site, number of excised segments, and surgical history. A nuanced preoperative evaluating approach considering patient age, surgical segments, and extent of resection is crucial.
