About this trial
In order to provide theoretical evidence for the comprehensive and standardized treatment of spinal metastases with pathological fractures and/or spinal cord compression, the investigators conduct this trial to investigate the efficacy and safety of IORT and postoperative SBRT in adjuvant treatment of metastatic spinal tumors after posterior decompression surgery by recruiting patients with spinal metastases who met the inclusion criteria, and randomly divided them into the following treatment cohorts: 1) decompression surgery + IORT (15-20 Gy, 20-50min); 2) decompression surgery and postoperative SBRT(30Gy, 5 fractions, 3 weeks).

Treatment groups
Trial outcomes
Primary outcomes
Local control rate
The local control of tumor in the surgical field
Secondary outcomes
Health-related quality of life
The "Functional Assessment of Cancer Therapy -General" (FACT-G) Scale (Minimum: 0; Maximum: 108 ) is utilized to evaluate the health-related quality of life after treatments, and higher scores mean a worse outcome.
Progression-free survival
The survival time between the day after treatments and the date of any evidence proving tumor progression or final follow-up
Overall survival
The survival time between the day after treatments and the date of all-cause death or final follow-up
Radiation-related complications
The complications assciated with the radiation process
