As shown in Table 2, multivariate Cox regression revealed that, after correction for patient age, elevated expression of TCTN1 protein was an independent risk predictor of both OS (HR =1.69, 95% CI =1.03-2.76, P =0.037) and PFS (HR =1.60, 95% CI =1.01-2.52, P =0.044) for GBM patients in the Chinese cohort. This evidence concerns the gene TCTN1 and glioblastoma.
