EGFR Gene, Targeted Mutation Analysis, 51 Mutation Panel, Tumor
Use
This test is useful for identifying non-small cell lung cancers that may respond to epidermal growth factor receptor-targeted therapies. By analyzing the mutation status of the EGFR gene, it aids in selecting patients who might benefit from EGFR-targeted treatment. Molecular genetic profiling, as performed in this test, is crucial for identifying actionable mutations and minimizing treatment costs and associated risks.
Special Instructions
Not provided.
Limitations
A negative (wildtype) result does not rule out the presence of mutations that may be present but below the detection limits of this assay (approximately 10%). It also does not exclude the presence of other activating mutations in the EGFR gene. Not all patients with detected activating EGFR mutations will respond to EGFR-targeted therapies. Rare genetic alterations, such as polymorphisms, could result in false-negative or false-positive results.
