title: [Current status of erlotinib and gefitinib in palliative therapy for NSCLC--does the EGF-R mutation state have any significance?].
abstract: In spite of intensive research and a huge amount of chemotherapy trials, the prognosis of metastastic non-small cell lung cancer (NSCLC) is still poor. Erlotinib and Gefitinb are tyrosine kinase inhibitors (TKIs) which act against the EGF receptor (EGF-R). Activation of mutations in the tyrosine kinase domain leads to an increase in effectiveness. What is the clinical impact of EGF-R mutation screening? What value do TKIs in 1st, 2nd and 3rd line have in therapy for metastatic NSCLC? Which treatment options exist after failure of TKI in the 1st line? These and other clinically relevant questions in the context of TKIs are discussed in the present comprehensive review.
