Abstract:
In order to determine the survival rate and prognostic factors of patients with intracranial oligodendroglioma as predictors of survival, a retrospective analysis of a total of 68 cases treated between 1982 and 1992 at our institute was performed. The 5-year and 10-year survival rates were 84.5% and 55.1% respectively while the median survival time was 116+/-5.3 months. The significant factors identified by the univariate analysis included the presence of preoperative seizure, the pre- and postoperative status, the presence of signs of increased intracranial pressure before operation and pathologic grade of the tumors. Factors such as age, types of chief complaints, blood types, the preoperative neurologic deficit, the size of tumor, the enhancement of tumor, cysts in tumor, the extent of removal and the postoperative seizure had no correlations with survival rates. The only significant prognostic factor determined by the multivariate analysis was the pathological grade(p=0.04).
