EGFR mutations occur in approximately 10-15 percent of NSCLC patients in Europe and 30-40 percent of NSCLC patients in Asia. Comparison of cobas EGFR Mutation Test v2 and PANAMutyper-R-EGFR for Detection and Semi-Quantification of Epidermal Growth Factor Receptor Mutations in Plasma and Pleural Effusion Supernatant. Hong W, Wu Q, Zhang J, Zhou Y. Prognostic value of EGFR 19-del and 21-L858R mutations in patients with non-small cell lung cancer. Blood samples were sent to a . EntroGen’s EGFR mutation analysis kit is a real-time polymerase chain reaction (PCR)-based assay that uses mutant-specific probes to identify the presence of EGFR mutations. Current data suggests that patients with metastatic NSCLC and the T790M mutation may benefit from T790M-targeted therapy (eg, osimertinib). Your doctor may use an eGFR blood test calculator that includes your creatinine test, age, sex, and race to calculate whether you fall in the high eGFR blood test bracket or low eGFR blood test. For tissue testing, order EGFRT / EGFR Gene, Mutation Analysis, 29 Mutation Panel, Tumor. The cobas ® EGFR Mutation Test v2 is a real-time polymerase chain reaction (PCR) test that identifies 42 mutations in exons 18, 19, 20 and 21 of the epidermal growth factor receptor (EGFR) gene, including the T790M resistance mutation. 1–4 Diagnostic tests are available that look for the presence or absence of mutations in tumour DNA encoding the EGFR gene. This test evaluates cell-free DNA (cfDNA) in the peripheral blood for the presence of the EGFR T790M mutation in patients with non-small cell lung cancer (NSCLC) and can be used to assess eligibility for targeted therapies. 1. EGFR T790M is the most common resistance mutation to develop upon progression with a 1st- or 2nd-generation EGFR-TKI. 17-21 of patients who progressed on 1st- or 2nd-generation EGFR-TKIs developed an EGFR T790M resistance mutation. This is because as people age, their muscle mass naturally begins to decrease. Clear results. Blood-based EGFR mutation testing demonstrated high specificity and good sensitivity, and offers a convenient and easily accessible diagnostic method to complement tissue-based tests. For tissue testing, order EGFRT / EGFR Gene, Mutation Analysis, 29 Mutation Panel, Tumor. EGFR T790M Mutation Detection in Circulating Cell-Free DNA by Digital Droplet PCR (ARUP Test Code 2012868) This test is ideally suited for testing blood plasma or cerebrospinal fluid for: EGFR T790M drug-resistant mutation detection at initial diagnosis or recurrence of non-small cell lung adenocarcinoma. Patients with a discordant mutation status in plasma and tissue, had improved survival outcomes compared with those with a concordant mutation status, which may be due to their lower tumor burden. This test provides rapid detection of the EGFR T790M mutation in peripheral blood from non-small cell lung cancer patients as an alternative for EGFR analysis of tissue. Clear results. Mutations in EGFR may lead to increased signaling 1,2. Conclusions. EGFR T790M mutation testing of non-small cell lung cancer tissue and blood samples artificially spiked with circulating cell-free tumor DNA: results of a round robin trial Virchows Arch . EGFR mutation testing detects mutations in the EGFR gene in cancer tissue, and plays an very important role in determining whether EGFR-targeted tyrosine kinase inhibitors (TKI) are beneficial for treating the tumor.. Plasma EGFR mutation tests for adults with locally advanced or metastatic non-small-cell lung cancer Medtech innovation briefing ... of PAXgene blood ccfDNA tubes AmoyDx EGFR 29 mutations detection kit £106.25 per test Including training DNA extraction kit £13.06 per test Based on list price of A number of genetic drivers of tumour growth have been identified in patients with non-small cell lung cancer (NSCLC); among these are mutations in the epidermal growth factor receptor (EGFR) gene. The cobas EGFR Mutation Test v2 is a real-time polymerase chain reaction (PCR) test for the qualitative detection of defined mutations of the epidermal growth factor receptor (EGFR) gene … Blood-based EGFR mutation testing demonstrated high specificity and good sensitivity, and offers a convenient and easily accessible diagnostic method to complement tissue-based tests. Blood samples at baseline, cycle 3, and progression were assessed for blood test detection rate, sensitivity, and specificity; concordance with matched tumor analysis (n = 238), and correlation with progression-free survival (PFS) and overall survival (OS). However, tumor tissues are often absent or insufficient for the testing. The prevalence of EGFR mutation in patients with non-small cell lung cancer: a systematic review and meta-analysis.
