Erlotinib accumulation in brain metastases from non-small cell lung cancer : visualization by positron emission tomography in a patient harboring a mutation in the epidermal growth factor receptor
INTRODUCTION: Drugs directed toward the epidermal growth factor receptor (EGFR), such as erlotinib (Tarceva®) and gefitinib (Iressa®), are used for the treatment of patients with advanced non-small cell lung cancer (NSCLC), including patients with brain metastases. However, whether erlotinib actually enters into brain metastases has not been adequately elucidated. In this study, we investigated th
