October 22, 2017. All breast cancer patients who develop a second primary cancer should undergo multigene panel testing, according to a paper published in JCO Precision Oncology. Now, with the introduction of a technology called multigene panel testing, people can learn about not just one but many inherited mutations at once. 1 Recent advances in next-generation DNA sequencing technology (NGS) have enabled these clinical tests and made them increasingly inexpensive to perform.2, 3 For hereditary cancer syndromes, studies have shown that NGS-based panel … With the advent of next-generation sequencing technologies, multigene panel testing (MGPT) is used increasingly for cancer risk assessment. Clinical Actionability of Multigene Panel Testing for Hereditary Breast and Ovarian Cancer Risk Assessment. Thus, instead of single‐gene testing, multigene panel‐based genetic testing is an alternative tool for screening hereditary cancer. With this technology comes the potential to reveal genetic variations that have uncertainty regarding cancer risk and management decisions. multigene panel for 25 genes responsible for breast cancer. Rana HQ, Gelman R, LaDuca H, et al. The Logistics of Multigene Panel Testing in Breast Cancer. Author Affiliations Article Information. (2015, August 13). Hereditary Cancer Syndrome Multigene Panels MOL.TS.182.A v1.0.2020 Introduction Hereditary cancer syndrome multigene panel testing is addressed by this guideline. CancerNext is a comprehensive 36-gene panel that identifies inherited risks for at least 8 types of cancers. If a gene mutation is found, multigene panel testing may: Give you a better understanding of your cancer risk than single-gene testing. Differences in TP53 Mutation Carrier Phenotypes Emerge From Panel-Based Testing. The objective in ordering a panel test is to identify a causative mutation by including other candidate genes. The American Society of Breast Surgeons updated consensus guidelines to recommend multigene panel testing for patients with cancer, including … Kapoor NS, Curcio LD, Blakemore CA, et al. Genetic testing can identify these mutations and guide patient management decisions. In clinical practice, panel testing may be ordered for patients who meet clinical guidelines for a single syndrome, such as hereditary breast and ovarian cancer syndrome. Multigene panel testing has proved useful as a diagnostic tool for disorders where similar phenotypes can be influenced by multiple genes. Multigene panel testing detects pathogenic BRCA1/2 mutations at equivalent rates as limited testing and increases the diagnostic yield. About one in 400 women have a deleterious mutation in the BRCA1 or BRCA2 genes that confers a risk for breast and ovarian cancers. Meeri Kim. Help your health care team decide what cancer screenings you might need beyond routine screenings. Interest in multigene panel testing was high (84%) and did not considerably differ by cancer status or ethnicity. Procedures addressed The inclusion of any procedure code in this table does not imply that the code is under management or requires prior authorization. CURE, Breast Cancer Special Issue 2017, Volume 1, Issue 1. Currently, the NCCN guidelines recommend testing of BRCA1 and BRCA2 for females with multiple breast primaries, if her first diagnosis was ≤50 years old. ScienceDaily. Numerous genetic mutations are linked to increased risk for breast cancer. Key Points. A universal strategy for multigene panel testing in all patients with CRC is an option versus the current strategy of guideline-based testing using family history and tumor features. Methods: Patients who met provincial eligibility criteria were tested at the Advanced Molecular Diagnostic Laboratory at Mount Sinai Hospital, Toronto. The JAMA Network Journals. 1. Over the past decade, multi-gene panel tests have gained traction in clinical settings. Question Is unselected genetic testing of all women with breast cancer cost-effective compared with testing based on clinical criteria or family history?. Results. Individuals with a pathogenic variant in one of the genes on this panel have an increased risk of developing cancer, many of … Genetic testing later in the care process means the results aren’t being used to help make surgery decisions. Desmond A, Kurian AW, Gabree M, et al. Multigene panel testing for hereditary breast/ovarian cancer risk assessment. In a recent Multigene panel testing (MGPT) for hereditary cancer predisposition is becoming increasingly available. Multigene panel testing is becoming more common for patients who are predisposed to Hereditary Breast and Ovarian Cancer Syndrome (HBOC). Meeri Kim. Breast Cancer Res Treat. We tested 1105 individuals using a 29-gene next-generation sequencing panel … Multigene panel testing for 21 genes in 8753 TNBC patients was performed by a clinical testing laboratory, and testing for 17 genes in 2148 patients was conducted by a Triple Negative Breast Cancer Consortium (TNBCC) of research studies. Extensive panel testing covering more than 40 genes is being increasingly marketed, but the diagnostic yield and action-ability remains questionable particularly for candidate genes such as TSC2 / PALLD which may not be relevant to patients with suspected hereditary breast cancer. Results: Out of the 80 patients tested, 30 had mutations with high and medium penetrance (25 pathogenic The authors noted that women with breast cancer have a 4%-16% lifetime risk of a second primary cancer. Epub 2019 Apr 12. Expansion of routine genetic testing for hereditary breast and ovarian cancer from conventional BRCA testing to a multigene test could improve diagnostic yield and increase the opportunity for cancer prevention in both identified carriers and their relatives. We use an economic decision model to assess whether the current knowledge on non-BRCA mutation prevalence, cancer … JAMA Oncol 2015; 1:943. Gene panels for hereditary breast and ovarian cancer risk assessment are gaining acceptance, even though the clinical utility of these panels is not yet fully defined. With the increase in uptake of multigene panels, testing for genes outside of BRCA1 and BRCA2 has become more prevalent. Generally, health insurance covers the cost of genetic testing recommended by a physician. Despite the rapid uptake of multigene panel testing (MGPT) for hereditary cancer predisposition, there is limited guidance surrounding indications for testing … MGPT allows for timely sequencing of multiple cancer susceptibility genes, is cost effective (1, 2), and leads to incremental genetic findings ().However, challenges remain to using MGPT for cancer risk assessment, including the … Patients at risk for hereditary breast cancer can safely benefit from up-front, more efficient, multigene panel testing. [4] The Invitae Multi-Cancer Panel analyzes 84 genes associated with hereditary cancers across several major organ systems. Background. These evaluate up to 43 breast cancer-related genes, compared with limited BRCA 1 and BRCA2 (BRCA1/2) tests. 2019 Jul;176(1):165-170. doi: 10.1007/s10549-019-05228-6. CancerNext is a comprehensive 36-gene panel that identifies inherited risks for at least 8 types of cancers. All of them received risk-appropriate genetic counseling and follow-up. Mark Robson, MD 1; Susan Domchek, MD 2. Multigene panel sequencing detected ovarian cancer-associated mutations in 11 genes in a large study of nearly 100,000 patients clinically tested for hereditary cancer risk. MGPT includes additional genes that may be important for a particular cancer (e.g., other genes beyond BRCA1/2 for breast cancer) MGPT can be helpful for heritable syndromes that include multiple cancers Multigene panel testing was about twice as likely as BRCA-only testing to identify disease-associated mutations. One vial of blood can shed light on a spectrum of predisposition and risk. Women with BRCA1 and BRCA2 mutations may pursue surgery to help prevent breast cancer, for example. 1 Breast Cancer Medicine and Clinical Genetics, Memorial Sloan Kettering Cancer Center, New York, New York. There were 477 triple-negative breast cancer patients identified; 331 met established criteria for genetic testing and 226 (68.3%) underwent genetic testing (multigene panel, n = 130 and BRCA1/2 testing, n = 96). Multigene panel testing for inherited cancer risk assessment is being rapidly integrated as a new approach to genetic testing. Multigene panel testing detects equal rates of pathogenic BRCA1/2 mutations and has a higher diagnostic yield compared to limited BRCA1/2 analysis alone in patients at risk for hereditary breast cancer. ... Sun‐Young Kong, Exon splicing analysis of intronic variants in multigene cancer panel testing for hereditary breast/ovarian cancer, Cancer Science, 10.1111/cas.14600, 111, 10, (3912-3925), (2020). “Patients at risk for hereditary cancer syndromes can benefit from upfront, more efficient, multi-gene panel testing without any sacrifice to BRCA testing capability,” said the study authors. But it was also more likely to … Findings In this cost-effectiveness microsimulation modeling study incorporating data from 11 836 women, unselected BRCA1/BRCA2/PALB2 testing at breast cancer diagnosis was extremely cost-effective … Multigene panel testing looks at multiple genes with one test. A study has found that most women now have multigene testing after a breast cancer diagnosis, but this genetic testing is happening later in the treatment plan than testing for only BRCA1 or BRCA2 mutations. Panel testing increases the VUS rate, mainly as a result of non-BRCA genes. Allison W. Kurian offers insight on using multigene panel testing to discover breast and ovarian cancer risks that may have otherwise went undetected. Broad Application of Multigene Panel Testing for Breast Cancer Susceptibility—Pandora’s Box Is Opening Wider. J Natl Cancer Inst 2018; 110:863. Technical questions remain, however, about the performance and clinical interpretation of gene panels in comparison with traditional tests. Multigene panel testing in unselected Israeli breast cancer cases: mutational spectrum and use of BRCA1/2 mutation prediction algorithms. Purpose: The aim of this study was to determine the diagnostic yield of multigene panel testing among patients referred with hereditary breast and ovarian cancer (HBOC).
