Abstract:
Objective To detect the expression of survivin protein in intramedullary gliomas and evaluated the clinical significance of the survivin expression. Method Seventeen cases of intramedullary gliomas were removed by using microsurgical technique.It composed of 8 cases of ependymomas and 9 ones of astrocytomas.The patients were followed up by MRI scanning periodically.The survivin protein expression of the intramedullary gliomas were examined by immunohistochemical stain (SP). Results Total resection of the tumor was obtained in 7 cases of ependymomas and subtotal resection was undertaken in the other one case.For 9 cases of astrocytomas,total resection of the tumor achieved in 3 cases,subtoal resection in 5 cases and partial resection in one case.Survivin expression was detected in 2 samples of ependymomas and 6 ones of astrocytomas.2 astrocytoma cases were moderate positive staining,who suffering from intracranial and vertebral subarachnoid dissemination of the tumor. Conclusion The result of microsurgical treatment for intramedullary ependymomas is satisfactory.The survivin expression in astrocytoma samples is significantly higher than that in ependymoma.Moderate positive staining may correlated with subarachnoid dissemination of the tumor.
