  1. Meta-analyses confirmsurvival benefit withchemotherapy 1990s Tumour growth is angiogenesis dependent Judah Folkman 1971 Routine identification of EGFR mut+ve & TKIs therapy 2010-11 Discoveryof cisplatin 1965 Discoveryof paclitaxel 1967 VEGF gene identified and EGFR isolated 1980s Bevacizumab / TKIsimprove survival in mol.unselected NSCLC 2000s

  2. Dimerisation of ligand-bound receptors • ATP binding and phosphorylation of tyrosine-kinase domain TKI TKI EGFR TKI blocks ATP binding and prevents activation of TK domain • Activation of two major intracellular signalling pathways • Cellular response to signals Ciardiello F and Tortora G. , NEJM 2008
