Stereotactic radiosurgery for spinal metastases with or without separation surgery

Area of Science:

• Neurosurgery
• Radiation Oncology
• Oncology

Background:

• Spinal metastases often cause significant epidural spinal cord compression.
• Surgical decompression followed by adjuvant stereotactic radiosurgery (SRS) can provide a safe margin for treatment.
• High-dose SRS may be a primary therapy if imaging shows a safe margin, potentially avoiding surgery.

Purpose of the Study:

• To evaluate the efficacy of stereotactic radiosurgery (SRS) for spinal metastases.
• To compare SRS-based approaches with radical oncological resection.
• To assess tumor control, neurological outcomes, and complications in patients treated with SRS.

Main Methods:

• Retrospective review of 57 patients treated with SRS between 2007 and 2011.
• Patients received SRS alone or after surgical decompression.
• Neurological outcomes and complications were assessed; radiographic response was evaluated via MRI.

Main Results:

• 69 spinal metastasis lesions were treated in 57 patients.
• 91.3% of tumors showed stability or regression.
• 98.6% of patients maintained or improved their Frankel score.

Conclusions:

• SRS, alone or combined with surgery, achieves durable local disease control for spinal metastases.
• This approach preserves or improves neurological function.
• SRS is an effective, less-invasive alternative to radical resection, regardless of tumor histology.
