Concerns about underutilization of genetic testing have spurred interest in broader peri-diagnostic testing. Genet Med 2015;17:51–57. It’s important for all pancreatic cancer patients to explore genetic testing with their healthcare teams. High prevalence of BRCA1 and BRCA2 germline mutations with loss of heterozygosity in a series of resected pancreatic adenocarcinoma and other neoplastic lesions. Slater EP, Langer P, Niemczyk E, . 4. Genet Med 2018;20:119–127. Vail PJ, Morris B, van Kan A, . Genetic testing should be considered in individuals for whom there is a personal or family history suggesting susceptibility to hereditary cancer and for whom results can potentially impact risk management and treatment. Tumor testing tends to be designed to address treatment actionability and prognosis.24 Therefore, a variant interpreted as pathogenic or likely pathogenic in the germline may be interpreted as normal or as a VUS in the tumor, if that variant has no clear clinical implications. Eccles DM, Mitchell G, Monteiro AN, . Deleterious germline mutations in patients with apparently sporadic pancreatic adenocarcinoma. Clinical trials: NCCN believes that the best management of any patient with cancer is in a clinical trial. The most recent Genetic/Familial High-Risk Assessment: Breast and Ovarian NCCN guidelines has a new section on multi-gene genetic testing. 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. These patients should be considered for referral to research studies that aim to define the functional impact of the gene variant, such as variant reclassification programs through clinical laboratories or registries.

All rights reserved. J Clin Oncol 2016;34:2010–2019. 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. Lancaster JM, Powell CB, Chen LM, . An analysis of screening outcomes of 411 asymptomatic individuals from 3 European centers showed that pancreatic cancer was detected in 7% of CDKN2A mutation carriers and <1% of those with familial pancreatic cancer.79 For the CDKN2A mutation carriers in whom a lesion was detected, 75% were resectable, with a 5-year overall survival rate of 24%.

Differentiation of human bone marrow-derived cells into buccal epithelial cells in vivo: a molecular analytical study. VALIDATION OF NCCN CRITERIA FOR GENETIC TESTING IN HBOC SYNDROME IN BRAZIL ... (NCCN Guidelines®) Genetic/Familial High-Risk Assessment: Breast and Ovarian, version 2.2016 (available at NCCN.org), and signalized according to the recommendation created by this Table 1. Conflicting interpretation of genetic variants and cancer risk by commercial laboratories as assessed by the prospective registry of multiplex testing. Trepanier A, Ahrens M, McKinnon W, . Evidence supporting pancreatic cancer screening comes from studies that include individuals harboring an associated germline mutation and/or those who have a particularly strong family history of pancreatic cancer (≥2 first-degree relatives on the same side of the family, or ≥3 first- or second-degree relatives on the same side of the family). This may include the relative closest to the family member with the youngest age at diagnosis, bilateral disease, multiple primary tumors, or other cancers associated with a suspected hereditary syndrome. Reports regarding germline findings that may impact medical management should come from laboratories that are certified by the College of American Pathologists (CAP) and CLIA, with some US states (eg, New York) having additional reporting requirements. Genet Med 2014;16:830–837. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Genetic/Familial High-Risk Assessment: Breast, Ovarian, and Pancreatic Version 1.2020 contains several updates including new and expanded sections on risk assessment and management related to three major cancer types, while also maintaining a more conservative approach toward testing practices where the evidence is still lacking. The above table presents the National Comprehensive … Cancer 2015;121:25–33. Clinical evaluation of a multiple-gene sequencing panel for hereditary cancer risk assessment. Cancer Res 2011;71:2222–2229. Gastroenterology 2012;142:796–804, quiz e14–15. J Clin Oncol 2015;33:244–250. Thus, although recognizing the rationale for widespread population screening, the panel recommends that universal testing for founder BRCA1/2 mutations in individuals of Ashkenazi Jewish ancestry, regardless of personal or family history, be offered primarily in the setting of longitudinal research studies. Incidental germline findings discovered through other sources (eg, participation in a research study) should be reviewed by a genetics professional.25 Confirmatory testing in these cases may be recommended, especially if the reporting laboratory is not appropriately certified. When screening is recommended, it may be performed with contrast-enhanced MRI/MRCP and/or endoscopic ultrasound.80,81,87 MRI and endoscopic ultrasound have been shown to be superior in detecting subcentimeter pancreatic cysts compared with CT.87 Screening at a high-volume center of expertise and in the context of a research study is preferred.

In support of improving patient care, National Comprehensive Cancer Network (NCCN) is jointly accredited by the Accreditation Council for Continuing Medical Education (ACCME), the Accreditation Council for Pharmacy Education (ACPE), and the American Nurses Credentialing Center (ANCC), to provide continuing education for the healthcare team. Calzone KA, Soballe PW. Participation in clinical trials is especially encouraged. 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 Genet Med 2014;16:407–412. N Engl J Med 2014;371:2488–2498. First, Ashkenazi Jewish ancestry without a personal cancer history is now included as a scenario for which genetic testing may be considered. Familial pancreatic cancer. Yurgelun MB, Chittenden AB, Morales-Oyarvide V, . 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. Mateo J, Porta N, Bianchini D, . Comparison of locus-specific databases for BRCA1 and BRCA2 variants reveals disparity in variant classification within and among databases. Kaufman B, Shapira-Frommer R, Schmutzler RK, .

Olaparib for metastatic breast cancer in patients with a germline BRCA mutation. 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.
