This study analyzed the influence of different stages of solitary spinal involvement on respiratory function, based on the spinal segment invaded by the metastases.Results: The highest proportion of solitary spinal metastases occurred at the thoracic level (49.7%), with the lowest proportion at the sacral level (3.9%). The largest number of patients were in the 60– 69-year age group (34.6%). There was no significant difference in pulmonary function among patients with spinal metastases at different segments (all P > 0.05). The highest vital capacity (VC), forced expiratory volume in one second (FEV1), and forced vital capacity (FVC) were observed in patients who were overweight (all P < 0.05). There were no significant relationships between pulmonary respiratory function and body mass index (BMI) groups in male patient with spinal metastases. In female patients, the highest VC, FEV1, FVC, and maximum voluntary ventilation were observed in patients who were overweight (all P < 0.05).Conclusion: Thoracic vertebral metastasis was the main type of solitary spinal metastatic tumor. Spinal metastases were more common at ages 60– 69 years. There was no significant difference in pulmonary function among patients with spinal metastasis at different segments. Lung function was better in patients with spinal metastases who were overweight, especially in female patients.Keywords: spinal metastases, pulmonary function, clinical features
