Research progress on target therapy of advanced non-small cell lung cancer / 药学实践杂志

ABSTRACT

Detection of biomarkers benefited many advanced non-small cell lung cancer (NSCLC ) patients .In recent years ,epidermal growth factor (EGFR) tyrosine kinase inhibitors (TKIs) represented by Gefitinib ,Erlotinib ,Afatinib and an-aplastic lymphoma kinase (ALK) TKIs represented by Crizotinib have remarkable efficacy .However ,the efficacy for most first-generation EGFR-TKI and ALK-TKI is weakened due to secondary resistance .Currently ,the third-generation EGFR-TKI which successfully against drug resistance is based on research and development of the second-generation .In addition ,there are many other targeted inhibitors of mutation sites for advanced NSCLC .Unfortunately ,the largest proportion of Kirsten rat sar-coma viral oncogene homolog (K-RAS) mutation is not targetable with small molecule inhibitors currently .Therefore ,based on mechanisms exploration of tumor driven gene mutation ,its target drug research and development will be greatly addressed in the future .
