Results demonstrated that iPFS2 (24.0 months, 95% CI: 19.270–28.730) and OS (38.0 months, 95% CI: 30.074–45.926) for the combination of third-generation TKIs and brain radiotherapy were significantly superior to those for brain radiotherapy alone (iPFS2: 8.0 months, 95% CI: 6.695–9.305; OS: 20.0 months, 95% CI: 24.108–23.116), with a highly significant difference ( P < 0.001; Table 5 , Fig. 6 G-H).
