摘要: Targeted therapies inhibiting the epidermal growth factor receptor (EGFR) have been introduced in treatment of patients with advanced non-small-cell lung cancer (NSCLC). Many inhibitors EGFR developed, targeting either extracellular domain antibodies or intracellular tyrosine kinase binding small molecules. The inhibitor (TKI) gefitinib (Iressa) was first targeted drug to be registered for NSCLC after failure chemotherapy. Given concurrently together platinum combination chemotherapy both TKIs and erlotinib (Tarceva) failed increase activity. Sequential therapy is currently being investigated further. Studies monoclonal antibody cetuximab (Erbitux) combined are ongoing. Side effects molecules mainly skin rash diarrhea, whereas do not give diarrhea. Selection patients, based on molecular markers patient characteristics, has become an important issue further development these drugs, given there activity a relatively group NSCLC. Newer drugs more than one pathway order find broader patients.
