EGFR gene targeted mutation analysis

EGFR (epidermal growth factor receptor) is a gene that, when mutated, can drive certain lung cancers and other malignancies. This test analyzes blood or tissue samples for specific EGFR mutations. Detecting these mutations is critical for patients with non-small cell lung cancer because it determines eligibility for targeted therapy drugs (like erlotinib or gefitinib) that specifically block the mutated EGFR protein. These targeted treatments are often more effective and better tolerated than traditional chemotherapy. This is a molecular diagnostic test that informs personalized cancer treatment strategies.
