Minagene’s EGFR Gene Testing is a specialized genetic analysis designed to identify mutations within the Epidermal Growth Factor Receptor (EGFR) gene in patients with lung cancer. This comprehensive testing approach utilizes state-of-the-art techniques, including next-generation sequencing (NGS) and other molecular methodologies, to detect EGFR mutations. By providing valuable genetic insights, this test aids in personalized treatment decision-making, particularly in the context of targeted therapies for lung cancer.


The EGFR Gene Testing employs NGS technology to analyze the DNA extracted from tumor samples or circulating tumor DNA (ctDNA). This approach allows for the detection of various EGFR mutations, including exon 19 deletions, exon 21 L858R point mutations, and other less common alterations. The test also assesses the presence of EGFR T790M mutation, which is associated with resistance to EGFR tyrosine kinase inhibitors (TKIs).

Key Highlights of the Test:

-Detection of EGFR Mutations: The EGFR Gene Testing identifies mutations within the EGFR gene, providing crucial information about the genetic profile of the tumor. It enables the detection of common activating mutations, such as exon 19 deletions and exon 21 L858R point mutations, as well as less common alterations within the EGFR gene.

-Personalized Treatment Selection: By identifying EGFR mutations, the test helps guide personalized treatment decisions, particularly in the context of targeted therapies for lung cancer. Patients with EGFR mutations may be candidates for EGFR TKIs, which have shown efficacy in this specific molecular subtype of lung cancer.

-Resistance Mechanism Assessment: The EGFR Gene Testing also assesses the presence of the EGFR T790M mutation, which is associated with acquired resistance to EGFR TKIs. Detection of this mutation is crucial for identifying patients who may benefit from alternative treatment strategies, such as third-generation EGFR TKIs or combination therapies.

-Monitoring Treatment Response: The test can be utilized to monitor treatment response and disease progression by detecting changes in EGFR mutation status over time. This enables physicians to assess treatment efficacy, identify emerging resistance mechanisms, and make informed decisions regarding treatment adjustments.

-Newly Diagnosed Lung Cancer: The EGFR Gene Testing should be considered in patients with newly diagnosed lung cancer, particularly those with non-small cell lung cancer (NSCLC), as EGFR mutations are more prevalent in this subtype. Identifying EGFR mutations at the time of diagnosis helps guide treatment decisions and optimize therapy for improved patient outcomes.

-Targeted Therapy Selection: The test is essential for selecting the most appropriate targeted therapy for patients with lung cancer harboring EGFR mutations. Positive EGFR mutation status is a predictive biomarker for the efficacy of EGFR TKIs, allowing for personalized treatment selection and optimization.

-Treatment Resistance Evaluation: In patients who initially respond to EGFR TKIs but later develop resistance, the EGFR Gene Testing can identify the EGFR T790M mutation, which is a common mechanism of acquired resistance. Detecting this mutation helps guide the selection of alternative treatment options to overcome resistance and improve treatment outcomes.

-Disease Progression Monitoring: The test can be used to monitor disease progression and treatment response over time. Serial testing enables the detection of emerging resistance mechanisms, guiding treatment adjustments and optimizing long-term management.
