cancer after failure of gefitinib treatment. Patients and methods Patients with advanced or …

Background Gefitinib and erlotinib are two orally active epidermal growth factor receptor
tyrosine kinase inhibitors used in the treatment of advanced non-small cell lung cancer …

Purpose This study was designed to evaluate the efficacy and toxicity of erlotinib in patients
with advanced non–small-cell lung cancer (NSCLC) who experienced disease progression …

PURPOSE: The use of erlotinib after gefitinib failure in patients with non-small cell lung
cancer (NSCLC) is not clearly clarified in clinical practice. We sought to compile the …

Background: Gefitinib and erlotinib are used to treat advanced non-small cell lung cancer
(NSCLC). Gefitinib is a common first-line treatment, but most patients develop resistance …
