egfr mutation testing guidelines

Use of the information is voluntary. The total amount of DNA in the sample is assessed by a control assay. Guideline Recommendations for EGFR Mutation Testing in Lung Cancer: Proposal of the Korean Cardiopulmonary Pathology Study Group. EGFR-activating mutations are detected in ~11% of NSCLC (adenocarcinoma) UK patients and these patients show a higher likelihood of response to treatment with EGFR tyrosine kinase inhibitors. published online before print ASCO endorsed the guideline with minor modifications. Acti-vating mutations in KRAS gene were shown to be of negative predictive value to TKIs. Expert Consensus Opinion: Physicians may use molecular biomarker testing in tumors with: any non–small-cell histology when clinical features indicate a higher probability of an oncogenic driver (eg, young age [< 50 years]; light or absent tobacco exposure). The concept is similar to Sanger sequencing (described in section 4.19), but the sample DNA is first fragmented into a library of small segments that can be sequenced in parallel reactions. With companion diagnostic tests now commercially available to guide clinicians in choosing appropriate therapies for their patients, laboratory professionals should become familiar with the important parameters for conducting and interpreting the tests for EGFR mutations. Introduction Guidelines for management of non-small cell lung cancer (NSCLC) strongly recommend EGFR mutation testing. Don’t settle for an unknown molecular status Recommendations for Endorsement That Have Been Reaffirmed or Updated From the 2013 Version, Table 2. ASCO will continue to follow CAP/IASLC/AMP’s guideline development updates on this topic and will incorporate future versions into our endorsement process as they become available. When a patient has already been treated with an EGFR-targeted tyrosine kinase inhibitor but does not appear to be responding favorably to the treatment, the healthcare practitioner may order additional EGFR mutation testing on a new sample, to check for specific EGFR mutations that may account for lack of a favorable response. Travel, Accommodations, Expenses: Boston Scientific, Consulting or Advisory Role: Auris Surgical Robotics, Veran Medical Technologies, Expert Testimony: Auris Surgical Robotics, Travel, Accommodations, Expenses: Auris Surgical Robotics, Table A1. 1–4 Diagnostic tests are available that look for the presence or absence of mutations in tumour DNA encoding the EGFR gene. Idylla EGFR Mutation Test. This endorsement reinforces the recommendations provided in the CAP/IASLC/AMP guideline and acknowledges the effort put forth by CAP/IASLC/AMP to produce an evidence-based guideline informing practitioners who care for patients with lung cancer. In cases where an initial activating EGFR mutation was present, T790M mutations were identified by cfDNA in approximately 30% to 40% of cases. Additional information is available at www.asco.org/thoracic-cancer-guidelines and www.asco.org/guidelineswiki. detect the presence of EGFR mutations in patients with advanced NSCLC. 21 had at least one mutation in EGFR and 13 had no EGFR mutation as determined by NGS analysis using the Ion AmpliSeq 50-gene Cancer Hotspot Panel v2 (Thermo Fisher Scientific). The type of evidence supporting the recommendations is not specifically stated. Fragment length analysis to detect exon 19 deletions and real-time PCR to detect the exon 21 mutation L858R are then used on samples that produce a negative result using Sanger sequencing. The Endorsement Panel agreed with the conclusions of the CAP/IASLC/AMP Expert Panel that there was adequate evidence to support the recommendation for ROS1 testing in patients with advanced-stage adenocarcinoma.1 ROS1 testing has been approved by the FDA based on a 50-person phase I clinical trial that demonstrated a 72% response rate to targeted therapy with crizotinib in patients with ROS1-rearranged non–small-cell lung cancer.5 An additional 32-patient retrospective study demonstrated an 80% rate of response for patients with ROS1-rearranged non–small-cell lung cancer who were treated with crizotinib.6. The first EGFR mutation test was commercialized in 2005, however EGFR testing recommendations were not included in the American Society of Clinical Oncology (ASCO) and National Comprehensive Cancer Network (NCCN) guidelines until 2010 [9, 10]. ASCO specifically disclaims any warranties of merchantability or fitness for a particular use or purpose. 4.8 In this test strategy, Sanger sequencing of exons 18 to 21 (described in section 4.19) is used to detect EGFR‑TK mutations in test samples with more than 30% tumour cells, and the therascreen EGFR RGQ PCR Kit (described in sections 4.1 to 4.4) is used to detect EGFR‑TK mutations in samples with less than 30% tumour cells. Expected median survival for patients with advanced lung cancer is approximately 1 year; however, treatment with targeted tyrosine kinase inhibitor (TKI) therapy can improve outcomes for patients who have certain molecular alterations that can be identified by molecular testing.1 In 2013, the College of American Pathologists (CAP)/International Association for the Study of Lung Cancer (IASLC)/Association for Molecular Pathology (AMP) issued a joint guideline for molecular testing for the selection of patients with lung cancer for epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) TKIs.2 ASCO endorsed that guideline,3 which included recommendations for selecting patients for testing, samples to be tested, and testing methodology. Key Question 2: What methods should be used to perform molecular testing? A comparison of methods for EGFR mutation testing in non-small cell lung cancer. OBJECTIVE: We aimed to determine population-based trends in the real-world uptake and impact in routine practice of these recently updated testing guidelines. The raw data are analysed using software to generate the DNA sequence. Since 2013, clinical practice guidelines recommend EGFR mutation testing of non-squamous NSCLC to select advanced-stage patients for first-line treatment using EGFR-TKIs. Key Question 3: Is molecular testing appropriate for lung cancers that do not have an adenocarcinoma component? As in other jurisdictions, in Australia, epidermal growth factor receptor (EGFR ) mutation testing is performed to determine eligibility for treatment with EGFR tyrosine kinase inhibitors (TKIs), which are recommended as first‐line therapy in patients with non–small cell lung cancer (NSCLC) whose tumors harbor a sensitizing mutation in the EGFR gene. In never or long time ex-smokers it is reasonable to consider testing squamous cell carcinomas. However, the testing landscape is complex. ASCO Meetings This clinical practice guideline addresses five overarching clinical questions: (1) Which new genes should be tested for in patients with lung cancer? EGFR mutation testing in non-small cell lung cancer (NSCLC). EGFR mutation testing based on plasma ctDNA in combination with tumor tissue (when required and feasible) is necessary to decide whether TKIs can be used in a patient diagnosed with NSCLC. Published date: Details of the search strategies, the study inclusion criteria, and outcomes of interest are available at http://www.archivesofpathology.org/doi/pdf/10.5858/arpa.2017-0388-CP. Thus, a standard set of guideline recommendations for liquid biopsy for EGFR mutation testing suitable for the Korean medical community is necessary. ASCO and the Expert Panel are aware that CAP/IASLC/AMP is monitoring the literature for the latest substantive publications in the field of molecular testing and that they plan to update their guideline when new high-quality practice-changing evidence becomes available. 12. National Comprehensive Cancer Network ® (NCCN ®) recommends clinicopathologic features such as ethnicity, smoking status, or histology NOT be used to select patients for EGFR mutational testing 4; BE SURE. One 10 μm FFPE tissue section was used for each Idylla™ test and all cases met the Idylla™ minimum tumor … Recommendations reprinted from Lindeman NI, Cagle, PT, Aisner, DL, et al. The sequencing reaction product is then cleaned up and analysed using capillary electrophoresis. The most common EGFR mutations (around 90%) are either … However, the ASCO Endorsement Panel did consider the new US Food and Drug Administration (FDA) approval of stand-alone BRAF testing in 2017 during its endorsement process. CAP/IASLC/AMP guideline development methods call for a review of the current guideline when practice-changing evidence is published or, at most, 4 years after publication. dayelf@kfshrc.edu.sa Lung carcinoma is subdivided into small cell carcinoma and non-small cell carcinoma (NSCLC). This version is no longer available, but is considered equivalent to the therascreen EGFR RGQ PCR Kit for the purpose of this assessment. This guideline will be distributed widely through the ASCO Practice Guideline Implementation Network. No Recommendation: There is currently insufficient evidence to support the use of circulating tumor cell molecular analysis for the diagnosis of primary lung adenocarcinoma, the identification of EGFR or other mutations, or the identification of EGFR T790M mutations at the time of EGFR TKI resistance. Relationships are self-held unless noted. 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. This older version uses the same methods as the newer therascreen EGFR RGQ PCR Kit, and detects 28 of the same mutations, but is not designed to detect the resistance mutation T790M. Editorial Roster In response to advances in the field, the College of American Pathologists (CAP), the International Association for the Study of Lung Cancer (IASLC), and the Association for Molecular Pathology (AMP) recently updated their recommendations for molecular testing for the selection of patients with lung cancer for treatment with targeted tyrosine kinase inhibitors. The CAP/IASLC/AMP recommendation on ALK IHC was based on published evidence that tests based on the 5A4 and D5F3 monoclonal antibodies showed sensitivities and specificities ranging from 95% to 100%. The PCR product is then prepared for analysis by heat denature and analysed using capillary electrophoresis under non-denaturing conditions. This article considers the use of pretest probability in non-small cell lung cancer (NSCLC) and how its use in EGFR testing has helped establish clinical guidelines on selecting patients for EGFR testing. With regard to osimertinib, a third-generation EGFR TKI that was approved by the China Food and Drug Administration as second-line treatment of EGFR-mutant advanced NSCLC, the Chinese guidelines recommend that the T790M mutation should be detected by … The DNA sequence is determined from the resulting pyrogram trace. Reprint requests: American Society of Clinical Oncology, 2318 Mill Rd, Suite 800, Alexandria, VA 22314; [email protected]org. Therefore, the ASCO panel chose to incorporate this into the recommendations and to recommend BRAF testing for all patients with advanced lung adenocarcinoma. Background: Epidermal growth factor receptor (EGFR) mutation testing in tumor tissue is now a common practice in selecting non-small cell lung cancer (NSCLC) patients for EGFR tyrosine kinase inhibitor (TKI) treatment.However, tumor tissues are often absent or insufficient for the testing. JCO Oncology Practice A series of enzymes incorporates nucleotides into the complementary DNA strand, generates light proportional to the number of nucleotides added and degrades unincorporated nucleotides. There is no argument over using epidermal growth factor receptor (EGFR) mutation status to guide the frontline treatment for advanced lung adenocarcinoma (LADC); however, the role of the testing in lung squamous cell carcinoma (LSQC) remains controversial. JCO Global Oncology No Recommendation: There is currently insufficient evidence to support the use of cfDNA molecular methods for the diagnosis of primary lung adenocarcinoma. Now, what can evolve are the partners. What is the clinical effectiveness of epidermal growth factor receptor mutation analysis using polymerase chain reaction for If they have an EGFR mutation right now and the patient relapses in 2, 3, or 4 years, you are still going to see that EGFR driver mutation. 10. Recommendation: ROS1 testing should be performed on all patients with advanced lung adenocarcinoma, irrespective of clinical characteristics. Sanger sequencing is a commonly used method, but there is a lot of variation in how it is carried out. 4.11 This test strategy combines in-house methods of pyrosequencing (to detect point mutations) with in-house methods of fragment length analysis (to detect deletions and insertions) for EGFR‑TK mutation detection. Recommendations reflect high, moderate, or low confidence that the recommendation reflects the net effect of a given course of action. The information is not continually updated and may not reflect the most recent evidence. If they have an EGFR mutation right now and the patient relapses in 2, 3, or 4 years, you are still going to see that EGFR driver mutation. 13. Tumor testing for mutations in the epidermal growth factor receptor (EGFR) gene is indicated for all newly diagnosed, metastatic lung cancer patients, who may be candidates for first-line treatment with an EGFR tyrosine kinase inhibitor. 11 Diagnostics Advisory Committee members and NICE project team, 12 Sources of evidence considered by the Committee. Category 1 added to ALK testing. A quality assessment of the guidelines on testing for EGFR mutations in patients with advanced NSCLC will also be presented. The fluorescence intensity is monitored as a function of time, and analysis software can determine the size of the fragments. Drives the growth and spread of metastatic NSCLC; Can be targeted with therapy specific to the mutation A quality assessment of the guidelines on testing for EGFR mutations in patients with advanced NSCLC will also be presented. Further, the information is not intended to substitute for the independent professional judgment of the treating provider, as the information does not account for individual variation among patients. Overall, the guideline scored 96% (Methodology Supplement). Importance of EGFR Testing . The NCCN Guidelines state that testing should … A real-time PCR instrument (Rotor‑Gene Q 5‑Plex HRM Platform for consistency with CE marking) is used to perform the amplification and to measure fluorescence. In many oncology services, BRAF V600E mutations as testing is also mandated as first-line BRAF/MEK inhibitors are more widely approved. Now, what can evolve are the partners. Three content experts provided a preliminary ASCO review of the guideline. Following this modification to the CAP/IASLC/AMP recommendations, the ASCO Expert Panel also chose to add BRAF testing to the routine tests listed in recommendations 4 through 7 for other molecular markers as well as to recommendation 9 for multiplexed genetic sequencing panels. The Molecular Testing Guideline for the Selection of Lung Cancer Patients for Treatment with Targeted Tyrosine Kinase Inhibitors was updated jointly by CAP, IASLC, and AMP. Squamous cell carcinoma; the following modified/added: Consider EGFR mutation and ALK testing are not routinely recommended except especially in never smokers and or small biopsy specimens, or mixed histology. DOI: 10.1200/JCO.2017.76.7293 Journal of Clinical Oncology The ASCO Post Further, an earlier version of the therascreen EGFR PCR Kit, which did include an assay for T790M, was used to analyse all samples in the IPASS trial. Samples are analysed on the PyroMark Q24 System and a plug-in report tool that simplifies analysis of the pyrogram trace is available. 13. • EGFR mutation testing recommended • EGFR mutation cannot be determined EGFR mutation status may be derived from either the primary or a reference laboratory. Mutation testing and subsequent therapies following first-/second-generation EGFR-TKI were described. a Rarely seen prior to EGFR TKI therapy, 46 and NCCN Guidelines (accessed in November 2019) 7 do not explicitly state that testing specifically for the T790M mutation should be done prior to first-line EGFR … Comparison of CAP/IASLC/AMP Recommendations and ASCO Endorsed Recommendations. It is appropriate to include ERBB2 (HER2) mutation analysis as part of a larger testing panel performed either initially or when routine EGFR, ALK, BRAF, and ROS1 testing is negative. 1,2 In patients diagnosed with advanced non-small cell lung cancer (NSCLC), the most common EGFR mutations are exon 19 deletions and an L858R point mutation in exon 21. 4.4 An older version of the test exists (the therascreen EGFR PCR Kit), which was inherited by Qiagen when they acquired DxS Ltd. Enter words / phrases / DOI / ISBN / authors / keywords / etc. EGFR Mutation Testing in plasma (cfDNA) Introduction. If EGFR testing is negative, Alkfusion Test should be performed. The performance characteristics of the EGFR Idylla assay were assessed; tissue suitability parameters and interpretation criteria to supplement automated mutation calling were established. Those mutations are always there. 4.17 High-resolution melt analysis is a screening method of mutation detection. The clinical practice guidelines and other guidance published herein are provided by the American Society of Clinical Oncology, Inc. (“ASCO”) to assist providers in clinical decision making. The ASCO Panel also included text from the CAP/IASLC/AMP narrative to provide context for two of the endorsed recommendations.

A systematic search of MEDLINE (Ovid Technologies, New York, NY) and PubMed from January 1, 2012, to June 27, 2016, was conducted. The goal of guideline endorsement is to increase the number of high-quality, ASCO-vetted guidelines available to the ASCO membership. ASCO Career Center Therefore, mutation testing is mandatory to identify these patients, given that selection based only on clinico-pathologic characteristics is inadequate. Expert Consensus Opinion: Laboratories should use, or have available at an external reference laboratory, clinical lung cancer biomarker molecular testing assays that are able to detect molecular alterations in specimens with as little as 20% cancer cells. Expert Consensus Opinion: ERBB2 (HER2) molecular testing is not indicated as a routine stand-alone assay outside the context of a clinical trial. Each section, including the Introduction, Methods, Results, Recommendations, Conclusions, and Supplemental Material were clear and well referenced from the systematic review. Fluorescent dye, which only binds to double-stranded DNA, is used to monitor the process. 4.14 The therascreen EGFR Pyro Kit (Qiagen) is a CE‑marked pyrosequencing kit. Permissions, Authors In addition, 18 new recommendations were developed by the CAP/IASLC/AMP Expert Panel (Appendix Table A1, online only). 4.6 The tumour tissue is first processed using the cobas DNA Sample Preparation Kit. We review the role of EGFR mutations in the diagnosis and management of NSCLC. After these initial methodology and content reviews, the ASCO Lung Biomarkers Endorsement Panel, which consisted of individuals with expertise in medical oncology, surgical oncology, pathology, pulmonology, radiology, and guideline development methodology, was formed and proceeded to meet via teleconference to review and discuss the Molecular Testing for the Selection of Lung Cancer Patients for Treatment with Targeted Tyrosine Kinase Inhibitors guideline. CancerLinQ 4.1 The therascreen EGFR RGQ PCR Kit (Qiagen) is a CE‑marked real-time polymerase chain reaction (PCR) assay for the targeted detection of 29 mutations in exons 18 to 21 of the epidermal growth factor receptor tyrosine kinase (EGFR‑TK) gene: 4.2 To ensure it complies with the CE marking, the DNA is first isolated from a specimen of formalin-fixed paraffin-embedded tissue using the QIAamp DNA FFPE Tissue Kit. Expert Consensus Opinion: Multiplexed genetic sequencing panels are preferred where available over multiple single-gene tests to identify other treatment options beyond EGFR, ALK, BRAF, and ROS1. ASCO Author Services Additional information, including a Methodology Supplement, slide sets, clinical tools and resources, and links to patient information at www.cancer.net, is available at www.asco.org/thoracic-cancer-guidelines and www.asco.org/guidelineswiki. Reviewers Molecular testing should be capable of identifying EGFR mutation, anaplastic lymphoma kinase (ALK) gene rearrangements, and, for the first time, ROS1 and programmed death ligand-1 (PD-L1) expression. Most guidelines recommend that all patients with an adenocarcinoma, probable or possible adenocarcinoma should have their tumour tested for EGFR mutations in exons 18-21. All relationships are considered compensated. This is the most recent information as of the publication date. Maybe you didn’t have a TP53 mutation before, but now you do. [2,5] Still, discordance rates of 20% to 30% when comparing cfDNA testing with tissue-based testing have been reported. A comparison of the CAP/IASLC/AMP and ASCO recommendations can be found in Tables 1 and 2. Finally, each of the three organizations instituted a separate review process to approve the guideline. Expert Consensus Opinion: KRAS molecular testing is not indicated as a routine stand-alone assay as a sole determinant of targeted therapy. The purpose of this ASCO guideline is to critically appraise and endorse the updated CAP/IASLC/AMP guideline on molecular testing for selection of patients with lung cancer for treatment with targeted TKIs. ASCO guidelines are posted on the ASCO Web site and most often published in Journal of Clinical Oncology and Journal of Oncology Practice. FDA approval was based on a 2016 phase II single-arm trial1 showing a disease control rate (DCR) of 58% with second-line therapy with dabrafenib and a DCR of 75% with second-line therapy with dabrafenib plus trametinib in patients with stage IV non–small-cell lung cancer who had BRAF V600E mutations.4 The CAP/IASLC/AMP Expert Panel indicated awareness of the FDA approval in their guideline narrative and stated that they will most likely recommend stand-alone BRAF testing in the next iteration of their guideline. 4.3 The limits of detection (the per cent mutant DNA present in a background of wild-type DNA, at which 95% or more replicates were determined positive) reported by the manufacturer for the different mutations ranged from 0.5% to 7.0%. JCO Clinical Cancer Informatics Testing for EGFR mutations has become a critical first step in personalised treatment of lung cancer. 4.9 In this test strategy, Sanger sequencing of exons 18 to 21 (described in section 4.19) is used to detect EGFR‑TK mutations in test samples with more than 30% tumour cells, and the cobas EGFR Mutation Test (described in sections 4.5 to 4.7) is used to detect EGFR‑TK mutations in samples with less than 30% tumour cells. In all cases, the selected course of action should be considered by the treating provider in the context of treating the individual patient. Thirty-four FFPE lung adenocarcinoma tissue samples were tested on the Idylla™ system. This study aims to explore current testing practices, logistics of testing, types of EGFR mutation, and prevalence of EGFR mutations in patients with advanced NSCLC … All steps are performed at least in duplicate to increase confidence that an identified mutation is real. ASCO guidelines are developed for implementation across health settings. The Expert Panel wishes to thank Scott Tagawa, MD, MS, Paul Hesketh, MD, and the Clinical Practice Guidelines Committee for their thoughtful reviews and insightful comments on this guideline. Epidermal growth factor receptor (EGFR) activating mutation are found in exons 18 to 21 of the EGFR gene, which is part of the gene coding for the tyrosine kinase domain of the EGFR protein. Strong Recommendation: In patients with lung adenocarcinoma who harbor sensitizing EGFR mutations and have progressed after treatment with an EGFR-targeted TKI, physicians must use EGFR T790M mutational testing when selecting patients for third-generation EGFR-targeted therapy. EGFR mutation testing in non-small ... manuscript is to provide an overview of EGFR mutations in NSCLC as well as to briefly discuss sample requirements and testing guidelines for EGFR mutation. The CAP/IASLC/AMP recommendation related to BRAF testing in patients with advanced adenocarcinoma was not endorsed by the ASCO Panel. ASCO provides this information on an “as is” basis, and makes no warranty, express or implied, regarding the information. An EGFR mutation test may be ordered by itself or as part of a panel (a series of tests to detect mutations in other genes such as KRAS, ALK and ROS1). In other words, there are many ways in which EGFR can be changed genetically. The DNA is first extracted from the sample and amplified using PCR. The second step is PCR amplification and detection of EGFR‑TK mutations using complementary primer pairs and fluorescently labelled probes. More information, including a Methodology Supplement, slide sets, and clinical tools and resources, is available at www.asco.org/thoracic-cancer-guidelines and www.asco.org/guidelineswiki. Some mutations confer sensitivity, and others confer resistance to anti-EGFR targeted therapies. Nucleotides are added sequentially to the amplified PCR product. EGFR ± ALK testing should be conducted as part of a multiplex/next-generation sequencing. Editor’s note: This American Society of Clinical Oncology clinical practice guideline provides recommendations, with comprehensive review and analyses of the relevant literature for each recommendation. Epidermal growth factor receptor (EGFR) activating mutation are found in exons 18 to 21 of the EGFR gene, which is part of the gene coding for the tyrosine kinase domain of the EGFR protein. detect the presence of EGFR mutations in patients with advanced NSCLC. The American Society of Clinical Oncology (ASCO) has policies and procedures for endorsing practice guidelines that have been developed by other professional organizations. Recommendation: Laboratories testing for EGFR T790M mutation in patients with secondary clinical resistance to EGFR-targeted kinase inhibitors should deploy assays capable of detecting EGFR T790M mutations in as little as 5% of viable cells. Subscribers Expert Consensus Opinion: Laboratories should ensure that test results that are unexpected, discordant, equivocal, or otherwise of low confidence are confirmed or resolved by using an alternative method or sample.
