Impacts of EGFR-mutation status and EGFR-TKI on the efficacy of stereotactic radiosurgery for brain metastases from non-small cell lung adenocarcinoma: A retrospective analysis of 133 consecutive patients

The present study demonstrated the upfront SRS strategy to offer a minimally invasive and effective treatment option for EGFR-mutant lung adenocarcinoma patients with limited BM. EGFR-TKI naïve patients were found to be a distinct subgroup for which a longer survival time and durable intracranial disease control can be expected.
