Also shown in Table 3, TERT promoter mutations (HR = 1.39; 95% CI, 1.13–2.17; P = 0.020) and long RTL (HR = 1.72; 95% CI, 1.18–2.50; P = 0.005) are predictors of poor OS for glioma patients as independently variable with respect to gender, age, pathological diagnosis, IDH1 mutations, MGMT methylation, radiotherapy and chemotherapy. The gene discussed is IDH1; the disease is glioma.
