Abstract
Telomerase reverse transcriptase (TERT) encodes the catalytic subunit of telomerase. The role of TERT in gliomagenesis has been extensively investigated. Since the influence of district, population, sample size, and experimental technology, our analysis, based on published articles, was aimed to obtain an accurate estimation of the relationship between TERT mutations and prognosis of glioma patients. PubMed, Web of science and Google Scholar databases were searched for potential articles. Finally, six studies with 2111 patients were included in the meta-analysis. Heterogeneity was evaluated by I2 statistics and P value. I2 > 50% and P < 0.05 indicated significant heterogeneity between included studies and random-effects model was used; otherwise, fixed-effects model was used for analysis. The results of meta-analysis was expressed as hazard ratio (HR) and 95% confidence interval (CI). The pooled results calculated by fixed-effects model suggested that TERT mutations were associated with poor prognosis of glioma patients (HR 1.68, 95% CI 1.43-1.97). In conclusion, TERT mutations may be associated with shorter survival of glioma patients.
