HWTS-TM001A-Human EGFR Gene 29 Mutations Detection Kit (Fluorescence PCR)


Lung cancer has become the leading cause of cancer deaths worldwide, seriously threatening human health. Non-small cell lung cancer accounts for about 80% of lung cancer patients. EGFR is currently the most important molecular target for the treatment of non-small cell lung cancer. The phosphorylation of EGFR can promote tumor cell growth, differentiation, invasion, metastasis, anti-apoptosis, and promote tumor angiogenesis. EGFR tyrosine kinase inhibitors (TKI) can block the EGFR signaling pathway by inhibiting EGFR autophosphorylation, thereby inhibiting the proliferation and differentiation of tumor cells, promoting tumor cell apoptosis, reducing tumor angiogenesis, etc., so as to achieve tumor targeted therapy. A large number of studies have shown that the therapeutic efficacy of EGFR-TKI is closely related to the status of EGFR gene mutation, and can specifically inhibit the growth of tumor cells with EGFR gene mutation. The EGFR gene is located on the short arm of chromosome 7 (7p12), with a full length of 200Kb and consists of 28 exons. The mutated region is mainly located in exons 18 to 21, codons 746 to 753 deletion mutation on exon 19 accounts for about 45% and the L858R mutation on exon 21 accounts for about 40% to 45%. The NCCN Guidelines for the Diagnosis and Treatment of Non-Small Cell Lung Cancer clearly states that EGFR gene mutation testing is required before EGFR-TKI administration. This test kit is used to guide the administration of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) drugs, and provide the basis for personalized medicine for patients with non-small cell lung cancer. This kit is only used for the detection of common mutations in the EGFR gene in patients with non-small cell lung cancer. The test results are for clinical reference only and should not be used as the sole basis for individualized treatment of patients. Clinicians should consider the patient's condition, drug indications, and treatment The reaction and other laboratory test indicators and other factors are used to comprehensively judge the test results.
