Abstract The prognosis of patients with brain metastases from non-small cell lung cancer (NSCLC) is poor. Tyrosine kinase inhibitor (TKI) significantly improves the prognosis of patients with epidermal growth factor receptor (EGFR) sensitive mutation. EGFR sensitive mutations are associated with the incidence of brain metastases in NSCLC and may affect the efficacy of radiotherapy and TKI therapy. Both EGFR-TKI and radiotherapy are effective for EGFR-mutant NSCLC with brain metastases. Whether the combination of EGFR-TKI and radiotherapy may improve the prognosis compared with EGFR-TKI or radiotherapy alone has been studied. Retrospective studies have indicated that upfront radiotherapy, especially upfront stereotaxic radiosurgery combined with EGFR-TKI may be more advantageous in improving the prognosis, but it is still controversial. Therefore, clinical research progresses on the radiotherapy for EGFR-mutant NSCLC patients with brain metastases were reviewed.
