【 摘 要 】

The study objective was to determine the recurrence rate of intracranial meningioma and the risk factors that are contributory to an increase in the incidence of recurrence. A prospective design was used in this study on meningioma patients treated at Cipto Mangunkusumo Hospital between 2010 and mid-2015. Data on the subjects were collected from the Departments of Neurology, Neurology, and Pathology, at the Universitas Indonesia/Cipto Mangunkusumo Hospital. The subjects were adults who had been previously diagnosed with meningioma. Follow-up was performed to assess the patients in relation to their initial clinical presentation. Neuroimaging was carried out to determine recurrence. The histopathological findings, extent of tumor resection (using Simpson's criteria), and Word Health Organization grade, were also determined. Immunohistochemistry was performed to evaluate the expression of progesterone receptor (PR), Ki-67, and vascular endothelial growth factor (VEGF). The recurrence rate was then analyzed to determine any correlation with the aforementioned risk factors. The recurrence rate was found to be 13%. Ki67, VEGF, and PR expression was positive in 9%, 73%, and 50% of the subjects, respectively. A significant correlation was not found between the study variables (tumor location, the scope of resection based on Simpson's criteria, histopathologic grade, mitotic index, i.e., Ki-67, and PR and VEGF expression in the meningioma tissue) and the recurrence of meningioma.
