Case ReportsMiliary brain metastases in 2 cases with advanced non-small cell lung cancer harboring EGFR mutation during gefitinib treatment.
Here we report 2 cases of non-small cell lung cancer (NSCLC) with sensitive epidermal growth factor receptor (EGFR) gene mutation that developed miliary brain metastases characterized by dementia and disorientation during gefitinib therapy. One patient's therapy was switched from gefitinib to chemotherapy followed by whole brain radiotherapy (WBRT), which resulted in disease progression with coma. ⋯ The other patient continued gefitinib during WBRT and achieved complete remission of the miliary metastases and lived 18 months longer. These results suggest that gefitinib concomitant with WBRT is an optional strategy for the treatment of patients with EGFR-mutated NSCLC with miliary metastases to prevent disease flare.
