Abstract
TERTp mutation was associated with older patients (â¥60 years) and frontally located gliomas. Old age, frontal location, and grade IV were found to be predictive factors of TERTp mutation. TERTp mutation resulted in poor prognosis in overall diffuse gliomas. TERTp mutation was not correlated with overall survival (OS) or progression-free survival (PFS) in the diffuse gliomas. However, TERTp mutations, in combination with MGMT methylation or IDH mutation, showed that there were statistical significant survival differences between MGMT-unmethylated/TERTp-mutated and MGMT-unmethylated/TERTp-wildtype subgroups in grade II gliomas. There was a statistical significant survival difference of OS between IDH-wildtype/TERTp-mutated and IDH-mutated/TERTp-mutated subgroups in grade III gliomas. No significant associations between survival and MGMT/TERTp or IDH/TERTp status were found in grade IV gliomas. In conclusion, the combination of TERTp with IDH or MGMT status may be a prognostic indicator depending on grades.
