Core Tip
Core tip: Dramatic changes have occurred in the last decades, concerning the treatment of lung cancer. The knowledge of clinical, pathological and molecular pathways has allowed sub-classifying non-small cell lung cancer (NSCLC), to a point where it has never been reached. The determination of activating mutations of epidermal growth factor receptor (EGFR) has permitted the use of EGFR tyrosine kinase inhibitors (TKIs), such as erlotinib and gefitinib in first, second and maintenance setting. However, acquired resistance develops at some stage of the disease, and second generation TKIs have been developed, but with similar results to traditional chemotherapy. With the arrival of third generation TKIs, a selective target mutational personalized therapy has accomplished better response rates, with a lower toxicity profile in phase I clinical trials. The question is should NSCLC patients with exon 19del and L858R point mutation in exon 21 be treated differently, once the driver oncogene is known? On the other hand, if patients with acquired resistance with EGFR T790M, should they also be treated targeting this predominant clone?
