Gefitinib for asymptomatic brain metastasis from advanced non-small cell lung cancer: Report of a favourable outcome

Abstract

Brain metastasis (BM) is common in patients with non-small cell lung cancer (NSCLC). Although epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have now been included as standard treatment options for NSCLC harboring EGFR-activating mutations, only a few prospective reports demonstrate the efficacy of these agents in a BM setting. We report a case of a patient with advanced NSCLC, in which oral gefitinib documented a significant antitumor effect on parallel progression of extracranial lesion and BM occurred during chemotherapy.
