Clinical Significance
This panel is comprised of mutational analysis of the EGFR and KRAS genes and assessment for ALK locus rearrangement using an FDA-cleared FISH assay. These are the most common tumor-associated genetic changes that have been shown to have prognostic and therapeutic consequences in non-small cell lung cancer (NSCLC) and help guide therapy. Patients with EGFR mutations are generally responsive to EGFR-directed kinase inhibitors, whereas those with evidence of ALK gene rearrangements are candidates for treatment with the ALK inhibitor crizotinib. The presence of KRAS mutation in lung adenocarcinoma predicts for non-response to kinase inhibitors and for tumors with inferior outcome.
