Abstract

The present study aimed to determine cyclooxygenase 2 (COX-2) and survivin expression levels in glioma tissues, and to investigate their association with clinicopathological factors and patient survival. Immunohistochemistry was performed to evaluate COX‑2 and survivin expression levels in paraffin‑embedded surgically resected tissues from 70 patients with glioma and 7 individuals with normal brain tissues. The association between COX‑2 and survivin expression levels and clinicopathological features was investigated using the χ2 test, and the survival time was analyzed using the Kaplan Meier method with log‑rank test. COX‑2 and survivin were overexpressed in glioma tissues, and higher expression levels were observed in glioma tissues of histological grades III‑IV compared with those in grade I‑II tumor tissues (P<0.05); however, the expression levels were not associated with gender, age, tumor size or location (P>0.05). There was a significant positive association between the expression levels of COX‑2 and survivin in the glioma tissues. Additionally, COX‑2 and survivin expression levels were significantly negatively correlated with the rate of survival. In conclusion, COX‑2 and survivin expression is positively associated with the pathological grade of a glioma and may contribute to glioma tumorigenesis. Therefore, COX‑2 and survivin may be sensitive predictors of a negative clinical prognosis for patients with glioma.
