The survival improvement for unselected patients with metastatic NSCLC has been modest, with a large surveillance, epidemiology, and end results (SEER) study, from the periods 1990–1993 to 2002–2005, showing increased survivals at 1 and 2 years of 13.2% to 19.4% and 4.5% to 7.8%, respectively.2 More recently, however, there has been a significant improvement in the understanding of the biology of lung cancer, with the discovery of new targets and development of several drugs with novel mechanisms of action. This chapter reviews the current knowledge of cancer genomics, the use of molecular markers, and results from clinical trials that are changing the therapeutic landscape of NSCLC.
