Mesothelioma victims families. There is no current consensus regarding the best method to detect egfr t790m mutations. The objective response rate was 64 95. Methionine is a larger nonpolar amino acidrather than directly blocking inhibitor binding to the.
T790m mutation testing rate and detection rate. Patients with a negative test result may still harbor the egfr t790m mutation. The presence of t790m at baseline egfr mutation testing using routine clinical molecular testing is rare 1 of cases and predicts the lack of response to egfr tki therapy first and second generation tkis 8.
31 patients did not have a sample collection and 6 additional patients had a tissuecytology rebiopsy but no tumor cells were detected in the sample. Pooled analysis of the positive and negative percent agreements between the cobas plasma and tissue tests for detection of t790m mutation were 61 and 79 respectively. The limit of detection of this assay for the detection of egfr mutations is influenced by the amount of cfdna in the blood.
Blood based testing for the presence of the mutation is recommended only when a tumor biopsy cannot be obtained. 31 however patients have to get tested to identify the mutation and to know if they can benefit from the new treatment. A multidisciplinary working group of pathologists laboratory medicine specialists medical oncologists a respirologist and a thoracic radiologist from across canada was convened to discuss best practices for egfr t790m mutation testing in canada.
Please see egfr t790m mutation testing section for more information. The aim of this study was to describe the concordance between local testing which used a variety of methods and central testing using the cobas egfr mutation test for egfr sensitizing mutations and the t790m resistance mutation. T790m also known as thr790met is a gatekeeper mutation of the epidermal growth factor receptor egfr.
The mutation substitutes a threonine t with a methionine m at position 790 of exon 20 affecting the atp binding pocket of the egfr kinase domain. This is a biological variable that cannot be controlled. Patients who test negative for the t790m mutation with the blood based test and their physicians should re evaluate the feasibility of tissue based testing to confirm the presence of the egfr t790m mutation.
For optimal patient management accurate egfr t790m testing is required. 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. Comparing cobas plasma test with next generation sequencing demonstrated positive and negative percent agreements of 90 or higher.
Patients with egfr t790m mutation nowadays have a treatment option known as third generation egfr tki eg. Mutation testing of a tissue specimen for egfr mutations should be considered for patients with a negative result with this test.
