Figure 2 Epidemiology of EGFR mutation in patients with NSCLC with brain metastasis. (A) The gender distribution based on types of EGFR mutations; (B) there are no significant association between mutational status and age; (C) EGFR mutations were associated with never smoking; (D) mutational status in the full cohort (n = 404).

Figure 3 The effect of different treatments on survival. (A) EGFR tyrosine kinase inhibitors (TKIs) plus whole body radiation therapy (WBRT) resulted in similar intracranial PFS (iPFS) and systemic PFS (sPFS) but worse overall survival (OS) than did EGFR TKIs alone in patients with NSCLC with EGFR mutation and brain metastasis; (B) EGFR TKIs plus WBRT and EGFR TKIs alone had iPFS, sPFS, and OS rates similar to those with first-line treatment in patients with NSCLC with EGFR mutation and synchronous brain metastasis; and (C) chemotherapy (Chemo) plus WBRT showed no superior iPFS, sPFS, and OS rates compared with chemotherapy alone in patients with NSCLC with EGFR unknown and wild-type status and brain metastasis.
