Abstract

The expression of O6-methyl­guanine DNA methyltransferase (MGMT) in different grade gliomas were analyzed in relation to its therapeutic effect and impact on disease prognosis. In total, 62 patients with glioma, who were admitted by neurosurgery and received surgical treatment and postoperative conventional chemoradiation, were selected for this study. Expression of MGMT was greater with an increase in brain glioma grade. Gender, age, tumor size and Karnofsky performance status (KPS) score did not differ with MGMT expression (P>0.05). Expression of MGMT in normal brain tissue was slightly significantly different than expression of MGMT in glioma tissue (P<0.05). The short‑term efficacy and survival time of the MGMT-negative expression group were better than those of MGMT-positive expression. MGMT was only treated as an index to monitor tumor recurrence or metastasis and a reference to judge the prognosis of patients. The expression level of MGMT in glioma had no relation with age, gender, tumor size, surgical approach and KPS score. For glioma patients with positive expression of MGMT, antineoplastic drugs of alkylating agent class should be avoided.
