The ability to predict treatment response and clinical (survival) outcomes is one of the two "holy grails" of cancer biomarker development, the other being early detection or risk stratification by population screening (1). In advanced nonsmall-cell lung cancer (NSCLC), small-molecule tyrosine kinase inhibitors (TKIs) of the epidermal growth factor receptor (EGFR) represent a breakthrough for targeted therapy, yet only a small proportion of patients (especially among nonEast Asians) appear to benefit from these expensive agents (2,3). Previous studies have shown that EGFR immunohistochemistry, tyrosine kinase domain mutations, and/or EGFR gene copy number by fluorescent in situ hybridization (FISH) are biomarkers that are potentially useful to select patients more likely to
