In the survival analysis of the cohort (n = 161) adjusted on surgical resection, MGMT promoter methylation status, number of alterations, age, tumor localization, MIB1 and performance status, EGFR substitutions were significantly associated with increased overall survival (OS) (HR = 0.43 [0.26; 0.72], P = .001), while CDKN2A/B loss and TP53 substitutions were associated with decreased OS (HR = 1.75 [1.08; 2.84], P = .023 and HR = 1.69 [1.04; 2.74], P = .034 respectively). This evidence concerns the gene TP53 and neoplasm.
