Expert consensus guidelines have defined minimum requirements for routine testing and identification of classical epidermal growth factor (EGFR) mutations (ie, exon 19 deletions and exon 21 L858R substitution) and anaplastic lymphoma kinase (ALK) rearrangements in advanced non-small-cell lung cancers of adenocarcinoma histology, with the intent of permitting use of these predictive biomarkers to select patients who will derive maximal benefit from approved oral tyrosine kinase inhibitors (TKIs) directed against EGFR and ALK, respectively.
