ATM and glioblastoma: In subsequent analysis employing the recommended diagnostic criteria for the molecular features of glioblastoma according to cIMPACT-NOW (n = 33), ATM mut(+) (n = 6) was shown to be associated with better in-field control than ATM mut(−) (n = 27) (1-y in-field control rate: 100.0% vs. 47.5%, p = 0.021; Fig. 2a, Additional File 2).
