Ask Questions of this Manuscript:
What is the background behind your study?
Foramen magnum, upper cervical spinal cord area are complex area.
What is the purpose of your study?
We have treated and assessed the effect of Gamma Knife radiosurgery for the tumors at the cranio-cervical junction.
Describe your patient group.
We have treated 13 patients with GKS during last 18 years. The 13
patients were comprised of 3 men and ten women, their ages ranging from
26 to 75 years(mean 50.06 years).
Describe what you did.
The diagnoses were 2 hemangioblstomas, 4 meningiomas, 4 astrocytomas, 1 hemangioma, 1 ependymoma, 1 hypoglossal tumor, etc. Surgical intervention was performed in 4 before radiosurgery. Mean maximal dose was 21.3 Gy, mean marginal dose 10.6 Gy.
Describe your main findings.
Mean follow up period was 37.1 months(8-142 months). Eight tumors had markedly decreased in size on follow up MRI. The other cases were stationary. There was no complication.
Describe the main limitation of this study.
This was a retrospective study.
Describe your main conclusion.
The result of this study suggests that GKS is effective for upper cervical tumor, foramen magnum tumor without neurological deficit.
Describe the importance of your findings and how they can be used by others.
Other centers should validate the role of radiosurgery at the craniocervical junction.
