CYBERKNIFE IN THE TREATMENT OF SPINALCORD TUMOURS
When treating benign spinal tumors with radiosurgery, the primary intermediate objective is to stop all tumor growth. Over the long term, these tumors will gradually shrink in size which may take a period of several years. Preliminary results with CyberKnife radiosurgery for meningioma and schwannoma show excellent control of tumor growth.
Treatment with CyberKnife radiosurgery utilizing a hypofractionated treatment regimen was indicated for maximum local control and to minimize the chance of injury to the spinal cord.
Outcome and Follow-Up
At 3-month follow-up:
* Neck, shoulder and arm pain dramatically decreased
* Neck and left arm mobility much improved
* MRI study showed no progression of meningioma
9-month follow-up:
* Improved neck and left shoulder mobility
* Left arm strength increasing
* Some numbness in left upper arm but improved compared to last visit
12-month follow-up:
* Increased left shoulder and neck mobility
* Increased left arm function
* No new symptoms or problems
22-month follow-up:
* Left arm range of motion improved, arm strength stable,
mild residual weakness
* No new problems
* No neck pain
* Follow-up MRI reveals no evidence of tumor progression and stability
of the previously treated lesion
Conclusion
The patient has experienced significant improvement since undergoing stereotactic radiosurgery. MRI shows no evidence of tumor progression. Follow-up will occur on an annual basis with continued MRI surveillance.
