This sequencing panel is useful in determining eligibility for tyrosine kinase inhibitor (TKI) therapy in patients with non-small cell lung cancer (NSCLC). The EGFR mutation is present in 10-15% of lung adenocarcinomas, and predicts response to drugs such as erlotinib.  This test covers actionable regions of exons 18-21, including the T790M mutation which predicts resistance to TKI therapy.
