Before completing these requirements, be sure your NCCN profile has been updated with your NAPB e-profile ID and date of birth. Mutations in different genes can cause the same type of cancer. Gene tests assess either one gene or a short piece of DNA. Gastroenterology 2012;142:796–804, quiz e14–15. Third-party services are available to assist patients with interpreting their raw data, but these services are not government-regulated. Population testing for cancer predisposing BRCA1/BRCA2 mutations in the Ashkenazi-Jewish community: a randomized controlled trial. For the 2020 update, the panel expanded the guidelines to include a focus on pancreatic cancer, including the addition of a new section on pancreas screening and genes associated with pancreatic cancer. Kurian AW, Hare EE, Mills MA, . Factors that limit the informativeness of the pedigree are small family size, a small number of individuals of the susceptible sex for sex-limited cancers, reduced penetrance, early deaths in family members (which precludes the possibility that they will develop adult diseases), prophylactic surgeries that remove an organ from subsequent risk for cancer (eg, hysterectomy for uterine fibroids in which the ovaries are also removed), adoptions, and inaccurate or incomplete information on family members (eg, in the case of adoption or divorce).48,49 It is also important to know the ancestry/ethnicity of the individual, because members of certain groups (eg, Ashkenazi Jewish) have increased risks of carrying pathogenic or likely pathogenic variants for specific diseases. Prevalence of pathogenic mutations in cancer predisposition genes among pancreatic cancer patients. If there is no access to longitudinal studies, then testing may be offered when pretest and posttest genetic counseling are available. This activity is supported by an independent medical education grant from Bristol-Myers Squibb. Genetic counselors can be a good referral source, should there be a need for genetic testing. The NCCN Guidelines are a statement of consensus of the authors regarding their views of currently accepted approaches to cancer treatment. The updated NCCN "Guidelines for Genetic/Familial High-Risk Assessment: Breast, Ovarian, and Pancreatic" are available from the NCCN website. Category 1: Based upon high-level evidence, there is uniform NCCN consensus that the intervention is appropriate. If no genetic counselor is available in your area, then referral to a breast surgeon is appropriate to discuss family history as well as a patient’s lifetime risk of breast cancer and need for genetic testing. Finally, a detailed medical and surgical history from the proband should be collected, and a physical examination should be performed by a qualified clinician when appropriate. Cancer statistics, 2018. NCCN Guidelines Version 2.2015 Table of Contents Genetic/Familial High-Risk Assessment: Breast and Ovarian NCCN Guidelines Index Genetics Table of Contents Discussion These NCCN Guidelines Insights summarize the panel’s discussion and most recent recommendations regarding criteria for high-penetrance genes associated with breast and ovarian cancer beyond BRCA1/2, pancreas screening and genes associated with pancreatic cancer, genetic testing for the purpose of systemic therapy decision-making, and testing for people with Ashkenazi Jewish ancestry. BRCA1, BRCA2, PALB2, and CDKN2A mutations in familial pancreatic cancer: a PACGENE study. Posttest counseling includes disclosure of results, a discussion of the associated medical risks, an assessment of the impact of the results on the individual’s emotional state, a discussion of the impact of the results on the medical management of the individual, and determination of how and where the patient will be screened for cancer risk.14 Counseling should include information on any available resources, such as disease-specific support groups, high-risk clinics, advocacy groups, and research studies.50 Probands should be advised regarding possible inherited cancer risk to relatives and available options for risk assessment and management. As a result of the above, NCCN recommends that genetic counseling and testing be offered to All individuals with exocrine pancreatic cancer First degree relatives of individuals diagnosed with exocrine pancreatic cancer Genes that will likely be ordered include BRCA1/2, as well as ATM, CDKN2A, STK11, TP53 and most Lynch syndrome genes Benefit of surveillance for pancreatic cancer in high-risk individuals: outcome of long-term prospective follow-up studies from three European expert centers. Slater EP, Langer P, Niemczyk E, . Unaffected patients should be informed that testing an affected relative first, whenever possible, is more informative than undergoing testing themselves. There is also the potential for impact on mortality rates, although long-term studies are needed in this area. 4. Robert Pilarski, MS, LGC, Panel Vice Chair, has disclosed that he has no relevant financial relationships. Category 2A: Based upon lower-level evidence, there is uniform NCCN consensus that the intervention is appropriate. J Natl Cancer Inst 2003;95:1548–1551. Eccles DM, Mitchell G, Monteiro AN, . Cancer Discov 2012;2:41–46. Colored markings in the algorithm show changes and the discussion aims to further the understanding of these changes by summarizing salient portions of the panel's discussion, including the literature reviewed. The NCCN Guidelines Insights highlight important changes in the NCCN Guidelines recommendations from previous versions. Current NCCN Recommendations for Prostate Cancer Genetic Testing – Summary: James L. Mohler, MD, discusses the rationale and development of the 2019 NCCN guideline recommendations on genetic testing for prostate cancer. Kapoor NS, Curcio LD, Blakemore CA, . Because some pathogenic or likely pathogenic variants are associated with rare autosomal recessive conditions (eg, Fanconi anemia or constitutional mismatch repair deficiency), testing the partner of a carrier of a pathogenic or likely pathogenic variant may be considered to inform reproductive decision-making.51. It is important to note that there may be inconsistencies in how programs and registries interpret the clinical actionability of some VUS, which may lead to confusion regarding medical management.18–20 Clinicians and scientists should work together to develop a VUS classification system as more information is discovered in research studies.21. Multigene panel testing detects equal rates of pathogenic BRCA1/2 mutations and has a higher diagnostic yield compared with limited BRCA1/2 analysis alone in patients at risk for hereditary breast cancer. Routine use of gene panel testing in hereditary breast cancer should be performed with caution. Also, gene tests can assess for small changes, such as an altered chemical "step" within the DNA "ladder," called gene mutations. JAMA 2018;319:2401–2409. Genetic Information Nondiscrimination Act of 2008. Updates include an expansion of genetic testing criteria to take into account other genes besides BRCA1/2 that are associated with an increased risk of breast and/or ovarian cancer, streamlined organization of these testing criteria, revisions to testing criteria related to Ashkenazi Jewish ancestry, genetic testing for the purpose of systemic therapy decision-making, an increased focus on phenotypically directed multigene panel tests, and the addition of information regarding pancreas screening and genes with associated pancreatic cancer.

All rights reserved. Genet Med 2014;16:830–837. Clinical trials: NCCN believes that the best management of any patient with cancer is in a clinical trial. In these cases, phenotype-directed testing based on personal and family history through a multigene panel test may be more efficient and/or cost-effective.29–31 Multigene testing may also be considered for individuals who tested negative for one particular syndrome but whose personal and family history is suggestive of an inherited susceptibility.29,32 Panel members indicated that it has become routine practice at their institutions to order phenotypically directed multigene panel tests to assess for pathogenic changes in multiple relevant genes simultaneously (see GENE-1, page 385). Weiss FU. Fibroblasts are also indicated when testing individuals with active or recent hematologic malignancies.17, A counseling dilemma is posed by the finding of a variant of unknown significance (VUS), a genetic alteration that may actually represent a benign polymorphism unrelated to an increased cancer risk or may indicate an increased cancer risk.

Germline BRCA mutations in a large clinic-based cohort of patients with pancreatic adenocarcinoma. JAMA 2006;295:1379–1388. For individuals potentially meeting established criteria for ≥1 hereditary cancer syndrome(s), genetic testing should be considered along with appropriate pretest and posttest counseling. Frequent detection of pancreatic lesions in asymptomatic high-risk individuals. Humphris JL, Johns AL, Simpson SH, . For most families in whom the presence of a pathogenic or likely pathogenic variant is unknown, it is best to consider testing an affected family member first, especially a family member with early-onset disease, bilateral disease, or multiple primaries, because that individual has the highest likelihood of a positive test result. J Clin Oncol 2014;32:2001–2009. Differentiation of human bone marrow-derived cells into buccal epithelial cells in vivo: a molecular analytical study. Lancet Oncol 2019;20:636–648.
