Dal Buono A, Puccini A, Franchellucci G, Airoldi M, Bartolini M, Bianchi P, Santoro A, Repici A, Hassan C. Lynch Syndrome: From Multidisciplinary Management to Precision Prevention. Cancers (Basel) 2024; 16:849. [PMID: 38473212 DOI: 10.3390/cancers16050849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/10/2024] [Accepted: 02/19/2024] [Indexed: 03/14/2024] Open
Abstract
BACKGROUND AND AIMS Lynch syndrome (LS) is currently one of the most prevalent hereditary cancer conditions, accounting for 3% of all colorectal cancers and for up to 15% of those with DNA mismatch repair (MMR) deficiency, and it was one of the first historically identified. The understanding of the molecular carcinogenesis of LS tumors has progressed significantly in recent years. We aim to review the most recent advances in LS research and explore genotype-based approaches in surveillance, personalized cancer prevention, and treatment strategies. METHODS PubMed was searched to identify relevant studies, conducted up to December 2023, investigating molecular carcinogenesis in LS, surveillance strategies, cancer prevention, and treatment in LS tumors. RESULTS Multigene panel sequencing is becoming the benchmark in the diagnosis of LS, allowing for the detection of a pathogenic constitutional variant in one of the MMR genes. Emerging data from randomized controlled trials suggest possible preventive roles of resistant starch and/or aspirin in LS. Vaccination with immunogenic frameshift peptides appears to be a promising approach for both the treatment and prevention of LS-associated cancers, as evidenced by pre-clinical and preliminary phase 1/2a studies. CONCLUSIONS Although robust diagnostic algorithms, including prompt testing of tumor tissue for MMR defects and referral for genetic counselling, currently exist for suspected LS in CRC patients, the indications for LS screening in cancer-free individuals still need to be refined and standardized. Investigation into additional genetic and non-genetic factors that may explain residual rates of interval cancers, even in properly screened populations, would allow for more tailored preventive strategies.

CANCER PATHOGENESIS AND THERAPY 2024; 2:1-14. [PMID: 38328708 PMCID: PMC10846329 DOI: 10.1016/j.cpt.2023.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 05/03/2023] [Accepted: 05/14/2023] [Indexed: 02/09/2024]
Abstract
Preimplantation genetic testing (PGT), which was developed as an alternative to prenatal genetic testing, allows couples to avoid pregnancies with abnormal chromosomes and the subsequent termination of the affected fetus. Originally used for early onset monogenic conditions, PGT is now used to prevent various types of inherited cancer conditions based on the development of PGT technology, assisted reproductive techniques (ARTs), and in vitro fertilization (IVF). This review provides insights into the potential benefits and challenges associated with the application of PGT for hereditary cancer and provides an overview of the existing literature on this test, with a particular focus on the current challenges related to laws, ethics, counseling, and technology. Additionally, this review predicts the future potential applications of this method. Although PGT may be utilized to predict and prevent hereditary cancer, each case should be comprehensively evaluated. The motives of couples must be assessed to prevent the misuse of this technique for eugenic purposes, and non-pathogenic phenotypes must be carefully evaluated. Pathological cases that require this technology should also be carefully considered based on legal and ethical reasoning. PGT may be the preferred treatment for hereditary cancer cases; however, such cases require careful case-by-case evaluations. Therefore, this study concludes that multidisciplinary counseling and support for patients and their families are essential to ensure that PGT is a viable option that meets all legal and ethical concerns.

Abstract
Objective To examine cognitive, relational, and social predictors of interest in and timing preference for cancer predisposition testing (CPT) and expanded carrier screening (ECS) offered in routine gynecologic care for women of reproductive age. Methods Women between 20 and 35 years old who were currently pregnant or had a prior pregnancy (N = 351) completed an online survey. Bivariate and multivariable analyses were used to identify significant predictors of women's interest in and timing preference for CPT and ECS. Results Most respondents reported high interest in CPT and ECS and preferred to have them when planning for a pregnancy. Perceived importance of genetic information and negative attitude towards uncertainty predicted interest in CPT and ECS in multivariable models. Genetic knowledge predicted preference for CPT or ECS when planning for a pregnancy. Conclusion Educational and decision support tools should be developed to enhance women's knowledge and awareness of CPT and ECS and to provide them with strategies to manage uncertainty. Innovation We examined women's timing preference for CPT and ECS and the impact of partner support and trust with gynecologist. A context-specific attitudes toward uncertainty scale was used to investigate women's particular perceptions of uncertainty in genetic testing.

Abstract
Cancer Predisposition Syndromes (CPSs), also known as Hereditary Cancer Syndromes (HCSs), represent a group of genetic disorders associated with an increased lifetime risk of developing cancer. In this article, we provide an overview of the reproductive options for patients diagnosed with CPS, focusing on the emerging role of Preimplantation Genetic Testing for Monogenic disorders (PGT-M). Specifically, we conducted a literature review about the awareness and acceptability of its application to CPSs. Based on the available data, the awareness of the applicability of PGT-M for CPSs appears to be limited among both patients and physicians, and a heterogeneous set of factors seems to influence the acceptability of the procedure. Our findings highlight the need for increasing education about the use of PGT-M for CPSs. In this context, guidelines developed by professional or institutional bodies would represent a useful reference tool to assist healthcare professionals in providing proper preconception counseling.

Abstract
PURPOSE Our aim was to describe the reproductive decisions and outcomes of BRCA-positive patients who used preimplantation genetic testing for monogenic disorders (PGT-M). METHODS We performed a retrospective case series of all PGT-M cycles for BRCA variants between 2010-2021 at a large urban academic fertility center. All patients who underwent ≥ 1 cycle of IVF with PGT-M for BRCA1 or BRCA2 were included. The primary outcome was total number of BRCA-negative euploid embryos per patient. RESULTS Sixty four patients underwent PGT-M for BRCA variants. Forty-five percent (29/64) were BRCA1-positive females, 27% (17/64) were BRCA2-positive females, 16% (10/64) were BRCA1-positive males, 11% (7/64) were BRCA2-positive males, and one was a BRCA1 and BRCA2-positive male. There were 125 retrieval cycles with PGT-M, and all cycles included PGT for aneuploidy (PGT-A). Eighty-six percent (55/64) of patients obtained at least one BRCA- negative euploid embryo, with median of 1 (range 0-10) BRCA-negative euploid embryo resulted per cycle and median 3 (range 0-10) BRCA-negative euploid embryos accumulated per patient after a median of 2 (range 1-7) oocyte retrievals. Sixty-four percent (41/64) of patients attempted at least one frozen embryo transfer (FET) with a total of 68 FET cycles. Fifty-nine percent (40/68) of embryos transferred resulted in live births. Subgroup analysis revealed different reproductive pathways for BRCA1-positive females, BRCA2-positive females, and BRCA1/2-positive males (p < 0.05). CONCLUSION PGT-M is a viable option for BRCA-positive patients to avoid transmission while building their families. Most patients in our cohort achieved pregnancy with BRCA-negative euploid embryos.

Abstract
Transgender and gender diverse (TGD) populations with hereditary cancer syndromes face unique obstacles to identifying and obtaining appropriate cancer surveillance and risk-reducing procedures. There is a lack of care provider knowledge about TGD health management. Lynch syndrome (LS) is one of the most common hereditary cancer syndromes, affecting an estimated 1 in 279 individuals. There are no clinical guidelines specific for TGD individuals with LS, highlighting a need to improve the quality of care for this population. There is an urgent need for cancer surveillance recommendations for TGD patients. This commentary provides recommendations for cancer surveillance, risk-reducing strategies, and genetic counseling considerations for TGD patients with LS.

Abstract
PURPOSE Although the role of CHEK2 germline pathogenic variants in cancer predisposition is well known, resources for managing CHEK2 heterozygotes in clinical practice are limited. METHODS An international workgroup developed guidance on clinical management of CHEK2 heterozygotes informed by peer-reviewed publications from PubMed. RESULTS Although CHEK2 is considered a moderate penetrance gene, cancer risks may be considered as a continuous variable, which are influenced by family history and other modifiers. Consequently, early cancer detection and prevention for CHEK2 heterozygotes should be guided by personalized risk estimates. Such estimates may result in both downgrading lifetime breast cancer risks to those similar to the general population or upgrading lifetime risk to a level at which CHEK2 heterozygotes are offered high-risk breast surveillance according to country-specific guidelines. Risk-reducing mastectomy should be guided by personalized risk estimates and shared decision making. Colorectal and prostate cancer surveillance should be considered based on assessment of family history. For CHEK2 heterozygotes who develop cancer, no specific targeted medical treatment is recommended at this time. CONCLUSION Systematic prospective data collection is needed to establish the spectrum of CHEK2-associated cancer risks and to determine yet-unanswered questions, such as the outcomes of surveillance, response to cancer treatment, and survival after cancer diagnosis.

Abstract
Preimplantation genetic testing for monogenic/single-gene disorders (PGT-M) is a procedure employed in the field of assisted reproductive technology to avoid the transmission of genetic diseases to the offspring. Hereditary cancer syndromes represent a diffuse and accepted indication for PGT-M, but take-up differs among the different disorders. Its use is markedly lower for the genes causing Lynch syndrome compared with the breast cancer type 1 or 2 susceptibility genes (BRCA1/2), despite the similar prevalence and severity of the two conditions. Reasons to explain this difference have not been explored. First, Lynch syndrome may be more frequently undiagnosed compared with hereditary breast and ovarian cancer syndrome. In addition, the different take-up may be due to different patient perceptions of the conditions and of the management options. Finally, this distinct attitude may depend on the awareness and sensibility of the professionals caring for affected patients. The authors' considerations are, however, speculative, and specific studies aimed at disentangling the causes of the different receptions of PGT-M are warranted to understand how to tackle this gap. In the meantime, we believe that empowerment regarding PGT-M of all individuals with hereditary cancer syndromes, including Lynch syndrome, is ethically due, and plead for a more active involvement of caregivers.

Abstract
BACKGROUND Guidelines from the European Hereditary Tumor Group as well as The Danish National Guidelines for Peutz-Jeghers Syndrome (PJS) state that both prenatal diagnosis and preimplantation genetic testing for monogenic disorders (PGT-M) should be offered to patients with PJS. However, only a few cases resulting in viable pregnancies have been published. OBJECTIVE We present two cases of PJS patients going through PGT-M for PJS. We highlight the awareness of this possibility and discuss the technical and ethical challenges of performing PGT-M for PJS. METHODS AND RESULTS Case 1: A 36-year-old male with PJS and his partner were referred for genetic counseling. The patient carried a pathogenic de novo variant in STK11. After a terminated pregnancy of a fetus carrying the same pathogenic variant, microsatellite polymorphic marker analysis was established, and the patient was offered PGT-M. The female partner of the patient gave birth to a healthy boy after five years of fertility treatment. Case 2: A 35-year-old female with PJS and her partner were referred for genetic counseling. She carried an inherited pathogenic STK11 variant. The couple was offered PGT-M. Genetic testing of the embryos was performed using microsatellite polymorphic markers. After two rounds of oocyte extraction a blastocyst predicted not to be affected by PJS was identified. The blastocyst was transferred; however, this did not result in a viable pregnancy. CONCLUSIONS PGT-M can be offered to patients with PJS. The process may be long and filled with ethical dilemmas requiring patients to be motivated and persistent.

[PMID: 35415820 DOI: 10.1007/s10689-022-00293-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 04/01/2022] [Indexed: 01/12/2023]
Abstract
Data on preimplantation genetic testing (PGT-M) in patients with genetic susceptibility to cancer are scarce in the literature, while there is, in our experience, a growing familiarity with assisted reproduction techniques (ART) among pathogenic variant heterozygotes. We performed a retrospective multicenter study of PGT-M outcomes among French patients with genetic susceptibility to cancer. Our objectives were to collect data on this complex issue, and to help cancer geneticists counsel their patients of reproductive age. We also wanted to increase awareness regarding PGT-M among cancer genetics professionals. Patients from three university hospital cancer genetics clinics who had requested PGT-M between 2000 and 2019 were included retrospectively. Data were extracted from medical records. Patients were then contacted directly to collect missing and up-to-date information. Out of 41 eligible patients, 28 agreed explicitly to participate when contacted and were therefore included. They carried PV in VHL (n = 9), APC (n = 8), CDH1 (n = 5), STK11 (n = 2), AXIN2, BRCA1, MEN1, and FH (n = 1). Seven patients were denied PGT-M based on multidisciplinary team meetings or subsequently by the ART hospital teams, two changed their minds, and two were yet to start the process. PGT-M was successful in seven patients (25%), with a mean age at PGT-M request of 27. Most had von Hippel-Lindau. PGT-M failed in the remaining ten, with a mean age at PGT-M request of 32. The main reason for failure was non-implantation of the embryo. Of these, four patients were pursuing PGT-M at the time of last contact. PGT-M outcomes in patients with cancer susceptibility syndromes were satisfactory. These patients should be informed about PGT-M more systematically, which would imply greater awareness among cancer genetics professionals regarding ART. Our series was not representative of cancer susceptibility syndromes in general; the predominance of cases with syndromes characterized by early-onset, highly penetrant disease is explained by the restrictive French guidelines.

Attitudes toward preimplantation genetic testing and quality of life among individuals with hereditary diffuse gastric cancer syndrome. Hered Cancer Clin Pract 2022; 20:31. [PMID: 36056367 PMCID: PMC9440538 DOI: 10.1186/s13053-022-00239-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Accepted: 08/12/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Hereditary Diffuse Gastric Cancer (HDGC) syndrome is an autosomal dominant hereditary cancer predisposition associated with germline pathogenic/likely pathogenic variants in the CDH1 gene. Identifying early stage HDGC is difficult, and prophylactic measures can be effective in preventing incidence. Preimplantation Genetic Testing (PGT) can provide information about CDH1 variant status, HDGC risk, and limit familial transmission of CDH1 variants. To date, however, little is known about the attitudes of individuals with CDH1 variants towards PGT. METHODS Given that little is known about the reproductive attitudes of individuals with HDGC, we recruited participants with CDH1 variants from a familial gastric cancer registry and administered a cross-sectional survey with open- and closed-ended response items. We assessed attitudes regarding PGT and the effect of HDGC on quality of life. RESULTS Participants (n = 21) were predominantly partnered (61.9%), had a personal cancer history (71.4%), and had biological children (71.4%). Interest in learning about PGT was high; 66.7% of participants were interested in PGT and 90.5% approved of healthcare providers discussing PGT with individuals with CDH1 variants. Attitudes regarding personal use were varied. Among all participants, 35% would not, 25% were uncertain, and 40% would use PGT. Personal philosophy and preferences for family and reproduction were key factors related to PGT attitudes. HDGC had moderate effects on participants' quality of life, including social relationships, health behaviors, and emotional experiences including worry about cancer risk and guilt regarding familial implications. CONCLUSION PGT was identified by participants as acceptable for use in a variety of contexts and benefits of reproductive counseling involving PGT may extend beyond CDH1 carriers to family members' reproductive behaviors. Dispositions towards PGT are governed by personal philosophy or belief systems. These findings can help guide providers counseling individuals with CDH1 variants.

Abstract
Background Although most neoplasms result from complex interactions between the individual’s genome and the environment, a percentage of cases is particularly due to inherited alterations that confer a greater predisposition to the development of tumors. Hereditary Neoplastic Syndromes have a high psychosocial and economic burden, in addition to being characterized by an increased risk for one or more types of cancer, onset of malignancy at a young age, high risk of secondary malignancies, and occurrence in successive generations of the family. Personal and family history, as well as pedigree, may be useful resources to estimate the risk for developing cancer, especially in Primary Health Care settings. Objective To identify and evaluate the evidence regarding the impact of using family history as a genomic technology for Hereditary Neoplastic Syndromes screening at Primary Health Care. Methods This systematic review protocol was elaborated in compliance with the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P). We will include all observational as well as experimental study designs published up to end of July 2022, and studies covering the impact of family history on screening for Hereditary Neoplastic Syndromes in primary health care. Qualitative studies, as well as guidelines, reviews, and studies undertaken in hospitals, outpatient clinic, or medical environments will be excluded. Five databases will be searched, including MEDLINE/PubMed, Cochrane Library, EMBASE, Web of Science, and LILACS. Additional sources will also be retrieved, including Clinical trials.gov-NIH, The British Library, and Google Scholar. No restriction to language or date will be employed in the search strategy. Three investigators will select studies independently, perform data extraction, and conduct the critical appraisal of the risk of bias and overall quality of the selected studies according to their designs. Regarding data synthesis, the study characteristics will be summarized and presented in tables and results will be presented according to the study design. A qualitative synthesis of data will also be provided in this systematic review. Discussion To the best of our knowledge, this systematic review will be the first to identify and critically assess evidence regarding the impact of using family history as a genomic technology for Hereditary Neoplastic Syndromes screening in Primary Health Care settings worldwide. This study is expected to provide consistent evidence that will aid the primary care decision-makers regarding hereditary cancer screening, thus helping individuals and families at risk for cancer.

Abstract
Most of breast cancer cases are sporadic; however, 15–20% are associated with family history, and some are inherited. Among those, deleterious mutations in BRCA1 and BRCA2 tumor suppressor genes are the most commonly encountered pathogenic germline variants (PGVs). Given the availability and affordability of multi-gene panel sequencing technologies, testing for PGVs is commonly practiced. With our enhanced understanding of cancer genetics and specific molecular alterations, the better acceptance of risk-directed screening and prevention, and the recent introduction of novel targeted therapies, management of BRCA-positive breast cancers is taking a new direction, focusing more on risk-reducing interventions, including mastectomy and salpingo-oophorectomy, and incorporating special treatment regimens, including platinum-based chemotherapy, and the recently-introduced PARP (poly (ADP)-ribose polymerase) inhibitors. Given the recent advances in reproductive technology and molecular medicine, younger women with PGVs may have the option of embryo selection through preimplantation genetic testing and diagnosis, thus preventing the potential transmission of the implicated genes to the next generations. In this review, we cover the clinical implications of identifying a pathogenic germline mutation in BRCA1 and BRCA2 genes in breast cancer patients, and their relatives, across the continuum of care – from cancer prevention and early detection, through active treatment and up to survivorship issues.

Abstract
The goal of this review is to provide an overview of evaluating patients with adenomatous polyposis of the colon, including elements such as generating a differential diagnosis, referral considerations for genetic testing, genetic testing options, and expected outcomes from genetic testing in these individuals. In more recent years, adenomatous colonic polyposis has evolved beyond the more robustly characterized familial adenomatous polyposis (FAP) and MUTYH-associated polyposis (MAP) now encompassing more newly described genes and associated syndromes. Technological innovation, from whole-exome sequencing to multigene panel testing, has dramatically increased the amount of genotypic and phenotypic data amassed in adenomatous polyposis cohorts, which has contributed greatly to informing diagnosis and clinical management of affected individuals and their families.

Abstract
The reproductive decision-making of young people (aged 15-39 years) with Li-Fraumeni syndrome (LFS), an early onset inherited cancer syndrome, has not been studied in depth. Using interpretive description methodology, we conducted semi-structured interviews with 30 young Australians (mean age 25.5 years) diagnosed with LFS or at 50% genetic risk. With reflexive thematic analysis, we show how young people's reproductive decision-making and ideals for family formation were shaped by a sense of genetic responsibility to ensure the health of future biological kin. Reproductive technology provided choices for family formation in the context of LFS and also complicated reproductive decisions, as these choices were difficult to understand, make, or carry out. We uphold that reproductive decision-making when living with LFS is a profoundly moral practice that may pose significant challenges for young people navigating their formative years. We offer genetic counseling practice recommendations to support individuals with LFS when making reproductive decisions.

Abstract
Background: Chromosomal abnormalities affect many children which lead to high rates of morbidity and mortality among them. So, preimplantation genetic testing (PGT) is an evolving technology used to detect a specific genetic disorder in embryos of a couple known to be carriers or affected by a specific mutation. Similarly, it could be used in advanced maternal age which is a high risk of chromosomal abnormalities. Although PGT is a solution for many inherited chromosomal disorders, many ethical dilemmas surround its application. Thus, the aim of this study is to evaluate the community awareness and acceptance of PGT which will eventually lead to a healthier society through disease-free babies in Eastern Province, Kingdom of Saudi Arabia (KSA). Methodology: A qualitative cross-sectional questionnaire-based study was conducted within the population of the Eastern Province of Saudi Arabia. The questionnaire was designed in Arabic and distributed electronically through social media platforms. Results: The study included 837 participants, whose ages ranged from 18 to 65 years with the mean age 33.5 ± 11.9 years. Good awareness and acceptance were detected among 53.7% of the old aged group (50 years or more) compared to 39.5% of the young age group. Also, 44.9% of female participants had good awareness in comparison to 34.2% of males (p=.033). Participants with a higher number of children had significantly higher awareness and acceptance of PGT. Also, 44.3% of participants who knew someone in need of assisted reproductive technology, had good awareness and acceptance levels compared to 36.9% of those who did not (p=.033). Conclusion: The perception of Eastern Province’s Saudi citizens toward PGT is found to be low. Increasing their perception toward such technology is needed as it is known that many chromosomal abnormalities are prevalent among this population, particularly sickle cell disease. Achieving this goal will eventually lead to decrease the burden of prevalent inherited diseases. Since Saudis' opinions are almost influenced by cultural and religious points of view, care should be given to these aspects.

Abstract
BACKGROUND Given a link between sarcomas and hereditary cancer predisposition syndromes, including Li-Fraumeni syndrome, the consideration for genetic counseling is recommended for all adolescent and young adult (AYA) patients diagnosed with sarcoma. The aim of this study was to evaluate factors influencing genetic consultations in AYA patients with sarcoma at the University of Wisconsin (UW). METHODS A retrospective chart review was performed on AYA patients diagnosed with sarcoma between the ages of 15 and 39 years who were seen at least once between 2015 to 2019 at UW. Our chart review identified discussions regarding genetics, referrals to genetics, genetic consultations, and results of genetic testing. Variables hypothesized to affect patient referrals for genetic consultation were identified a priori. Descriptive statistical methods and a univariate analysis were used to identify patient characteristics associated with genetic counseling referral. RESULTS We identified 87 AYA patients with sarcoma. Only 19 (22%) of these patients had documentation of a discussion about genetics, 15 (17%) of whom were subsequently referred for genetic consultation. Of these 15 patients, 9 (60%) were seen in consultation. All 9 patients seen by genetics underwent genetic testing, with 4 (44%) of these patients having identified heritable cancer predisposition syndromes. Likelihood for genetics referral was linked most strongly to documented genetics discussion with an oncology provider (P<.001). CONCLUSIONS Despite the recommendation for consideration for genetic counseling in AYA patients with sarcoma, <25% of such patients in our study had a documented discussion about genetics. Supporting this need, all referred patients met criteria for genetic testing, and 44% of tested patients were found to have a heritable cancer predisposition syndrome. These data support the initial conversation by a provider as critical to genetic referral and suggest the need for more specific national recommendations for the genetic evaluation of all AYA patients with sarcoma.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis is an option for most patients with ulcerative colitis or familial adenomatous polyposis who require colectomy. Although the construction of an ileal pouch substantially improves patients' health-related quality of life, the surgery is, directly or indirectly, associated with various structural, inflammatory, and functional adverse sequelae. Furthermore, the surgical procedure does not completely abolish the risk for neoplasia. Patients with ileal pouches often present with extraintestinal, systemic inflammatory conditions. The International Ileal Pouch Consortium was established to create this consensus document on the diagnosis and classification of ileal pouch disorders using available evidence and the panellists' expertise. In a given individual, the condition of the pouch can change over time. Therefore, close monitoring of the activity and progression of the disease is essential to make accurate modifications in the diagnosis and classification in a timely manner.

Abstract
BRCA1 and BRCA2 pathogenic variant carriers have a high lifetime risk of developing breast and ovarian malignancies. Given the risks and significant ramifications of undergoing risk-reducing surgeries, many pathogenic variant carriers unaffected by cancer (previvors) struggle with family planning and reproductive decision making. The objective of this study was to determine the attitudes and practices of BRCA1 and BRCA2 pathogenic variant carriers with respect to family planning decision making. A cross-sectional survey was conducted of BRCA1 and BRCA2 previvors at four Northeastern medical centers. The survey was administered electronically via email using REDCap. The survey included demographic information as well as questions about genetic testing, prophylactic surgeries, family planning, and partnering. Data were analyzed with Fisher's exact tests and t tests. The survey was completed by 139 of 422 BRCA1 and BRCA2 pathogenic variant carriers (response rate 33%). Thirteen were excluded from analysis due to self-reported cancer history. Of the remaining 126, 21 (16.7%) were male and 105 (83.3%) were female. Female participants <35 years old at the time of genetic testing were significantly more likely than those 35 or greater to report feeling urgency to have a family after finding out about their BRCA1 and BRCA2 pathogenic variant (p < 0.0001). Younger women also reported their genetic status had a stronger impact on their romantic relationships (p = 0.029). Men were significantly more likely to report that they felt no urgency to have a family compared to women (p < 0.0001). Our study reflects the complex decision making for previvors and the intricacies of family planning in this population. Providers can use this knowledge as a guide to counsel patients about reproductive options.

Comprehensive analysis of germline mutations in northern Brazil: a panel of 16 genes for hereditary cancer-predisposing syndrome investigation. BMC Cancer 2021; 21:363. [PMID: 33827469 PMCID: PMC8028728 DOI: 10.1186/s12885-021-08089-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Accepted: 03/23/2021] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Next generation sequencing (NGS) has been a handy tool in clinical practice, mainly due to its efficiency and cost-effectiveness. It has been widely used in genetic diagnosis of several inherited diseases, and, in clinical oncology, it may enhance the discovery of new susceptibility genes and enable individualized care of cancer patients. In this context, we explored a pan-cancer panel in the investigation of germline variants in Brazilian patients presenting clinical criteria for hereditary cancer syndromes or familial history. METHODS Seventy-one individuals diagnosed or with familial history of hereditary cancer syndromes were submitted to custom pan-cancer panel including 16 high and moderate penetrance genes previously associated with hereditary cancer syndromes (APC, BRCA1, BRCA2, CDH1, CDKN2A, CHEK2, MSH2, MSH6, MUTYH, PTEN, RB1, RET, TP53, VHL, XPA and XPC). All pathogenic variants were validated by Sanger sequencing. RESULTS We identified a total of eight pathogenic variants among 12 of 71 individuals (16.9%). Among the mutation-positive subjects, 50% were diagnosed with breast cancer and had mutations in BRCA1, CDH1 and MUTYH. Notably, 33.3% were individuals diagnosed with polyposis or who had family cases and harbored pathogenic mutations in APC and MUTYH. The remaining individuals (16.7%) were gastric cancer patients with pathogenic variants in CDH1 and MSH2. Overall, 54 (76.05%) individuals presented at least one variant uncertain significance (VUS), totalizing 81 VUS. Of these, seven were predicted to have disease-causing potential. CONCLUSION Overall, analysis of all these genes in NGS-panel allowed the identification not only of pathogenic variants related to hereditary cancer syndromes but also of some VUS that need further clinical and molecular investigations. The results obtained in this study had a significant impact on patients and their relatives since it allowed genetic counselling and personalized management decisions.

Abstract
Couples who are at risk of transmitting a genetic disease to their offspring may face difficult challenges regarding reproductive decision-making. Deciding if, and how, to purse their child wish can be a demanding process. This study aims to describe the reproductive joint decision-making process of genetically at-risk couples. A qualitative study was conducted with 16 couples (N=31) at risk of transmitting a genetic disease to their offspring and who received genetic counseling. Most couples were not aware of all available reproductive options in the Netherlands. A variety of motives was reported with almost all couples expressing a preference towards a reproductive option in which the child is genetically related to both parents. Only a few couples considered other options such as the use of donor gametes, adoption, and foster parenting. All couples indicated that they had multiple conversations to reach a mutually supported reproductive decision. Several carriers reported feelings of guilt and in some couples, the woman appeared to have a greater impact in the decision-making process as she should carry a pregnancy and should undergo medical treatments. This study provides insight in the extensive decision-making process of genetically at-risk couples and the role of both partners in this process. These findings can guide the development of genetic counseling (e.g., increase awareness of available reproductive options) and decision support for these couples.

Abstract
KEY CONTENT Lynch syndrome is an autosomal dominant condition closely associated with colorectal, endometrial and ovarian cancer.Women with Lynch syndrome are at increased risk of both endometrial and ovarian cancer and should be offered personalised counselling regarding family planning, red flag symptoms and risk-reducing strategies.Surveillance for gynaecological cancer in women with Lynch syndrome remains controversial; more robust data are needed to determine its effectiveness.Universal testing for Lynch syndrome in endometrial cancer is being adopted by centres across Europe and is now recommended by the National Institute for Health and Care Excellence; thus, gynaecologists must become familiar with testing strategies and their results.Testing strategies involve risk stratification of cancers based on phenotypical features and definitive germline testing. LEARNING OBJECTIVES To define the pathogenesis of Lynch syndrome and its associated gynaecological cancers.To understand the testing strategies for Lynch syndrome in women with gynaecological cancer.To learn how best to counsel women with Lynch syndrome regarding gynaecological cancer and risk-reducing strategies to enable informed decision-making. ETHICAL ISSUES Offering gynaecological surveillance despite a lack of robust evidence for its clinical effectiveness may falsely reassure women and delay risk-reducing hysterectomy.Genetic testing may yield variants of unknown significance with ill-defined clinical implications, which can lead to confusion and anxiety.Genetic testing has implications not only for the individual, but also for the whole family, so expert counselling is crucial.

Abstract
The detection of germline BRCA1/2 pathogenic variant has relevant implications for the patients and their family members. Family planning, prophylactic surgery and the possibility of preimplantation genetic testing for monogenic disorders (PGT-M) to avoid transmittance of pathogenic variants to the offspring are relevant topics in this setting. PGT-M is valuable option for BRCA carriers, but it remains a controversial and underdiscussed topic. Although the advances in PGT technologies have improved pregnancy rate, there are still several important challenges associated with its use. The purpose of this review is to report the current evidence on PGT-M for BRCA1/2 carriers, ethical concerns and controversy associated with its use, reproductive implications of BRCA pathogenic variants, underlying areas in which an educational effort would be beneficial as well as possibilities for future research efforts in the field.

Abstract
This study aimed to test the associations of religious orientation (extrinsic, intrinsic, and quest) and secularism of state with individuals' attitudes towards the pre-implantation genetic diagnosis of embryos. Moreover, we tested the mediating effects of secularism of state on the relationship between religious orientations and attitudes towards this issue related to embryos. Participants were 312 Catholic Italians that completed a questionnaire containing measures of investigated constructs. Results showed that attitude towards pre-implantation genetic diagnosis negatively correlated with intrinsic religious orientation and positively with extrinsic religious orientation and secularism. Moreover, results indicated that secularism mediated the relationship between extrinsic and intrinsic orientation and attitude towards pre-implantation genetic diagnosis. Taking together these results indicate that real endorsement with religion is associated with the refusal of pre-implantation genetic diagnosis because intrinsic religious orientation is related to the desire for state laws to follow religious principles; on the other hand, the use of religion for utilitarian reasons is associated to the acceptance of pre-implantation genetic diagnosis in order to have a religious state and then maintain Catholics’ privileges.

Abstract
In the era of precision medicine, patients must manage the uncertainty caused by ambiguous genetic information. To aid health practitioners in effectively communicating genetic information, this study classified the types of uncertainty involved in these communication processes. A search of recent literature turned up 64 articles that measured and/or discussed patients' perceptions and/or feelings of uncertainty related to the communication process of cancer-related genetic information. In reviewing these papers, six types of uncertainty regarding cancer-related genetic information were identified: (1) uncertainty about understanding genetic information (n = 25; 39.1%); (2) uncertainty about future cancer risks (n = 34; 53.1%); (3) uncertainty about managing known genetic information or mutation status (n = 33; 51.6%); (4) uncertainty about the utility of genetic information (n = 5; 7.8%); (5) uncertainty about genetic test results before undergoing testing or receiving the results (n = 10; 15.6%); and (6) uncertainty about the impact of genetic results on family and life (n = 11; 17.2%). These six types of uncertainty serve as a helpful taxonomy for developing, validating, and utilizing future measures of uncertainty in the context of cancer-related genetic risk communication.

Abstract
OBJECTIVE Adolescent and young adult (AYA) cancer patients have distinct medical and psychosocial needs and fertility is a key concern. Early age of onset is a risk factor for hereditary cancer and AYAs are more likely to experience reduced fertility. This has implications for future family building decisions and fertility preservation (FP) and genetic testing/counseling (GT/GC) education. METHODS Patients diagnosed with cancer between the ages of 18 and 39 and health care providers (HCPs) who treat AYA cancer patients were recruited from a single institution. Qualitative interviews explored AYA patients' and HCPs' concerns regarding their experiences discussing genetics and FP. RESULTS The majority of patients (n = 17) were female (59%), and the majority of HCPs (n = 18) were male (67%). Overall, participants had differing perceptions of FP and GT/GC-related information provided during the clinical visit. Patients indicated initiating the conversation about FP and did not recall HCPs discussing GT/GC with them. HCPs indicated patients were often overwhelmed with too much information and comprehension of this discussion is limited. HCPs also felt patients' emotions/beliefs determined their information-seeking behavior specific to FP and GT/GC. Participants felt educational materials should be developed and delivered in a video format depicting a patient-provider interaction or patient testimonial. CONCLUSION AYA patients are often overwhelmed by a cancer diagnosis; the complexity/volume of information regarding FP and GT/GC may hinder understanding and decision-making about family building. Educational materials that help patients understand what questions to ask HCPs about FP and GT/GC should be developed to improve knowledge, psychosocial well-being, and future family building decisions.

Abstract
Background: When discussing matters of reproduction, the 2015 revised guidelines for the management of medullary thyroid carcinoma recommend that patients diagnosed with multiple endocrine neoplasia type 2A (MEN 2A) are informed about the option of Preimplantation Genetic Testing for Monogenic Disorders (PGT-M). In addition, patients seem to have a genuine interest in reproductive options. However, there are just two reports worldwide of this technology being used for patients with MEN 2A. We here present, in a Danish couple where the man has MEN 2A, the first European family with children born after PGT-M. Objective: To report the results of PGT-M in relation to multiple endocrine neoplasia type 2A with the aim to increase awareness among physicians treating this and other genetic disorders. Methods: A Danish couple was referred to the PGT Center at Copenhagen University Hospital Rigshospitalet and opted for PGT-M after counseling by a clinical geneticist and a fertility doctor. The embryos were diagnosed using microsatellite polymorphic marker close to RET. Results: The couple had two healthy children born in 2017 and 2019 as a result of a total of three ICSI treatments including controlled ovarian stimulation, oocyte retrieval and PGT-M, and a total of six blastocyst transfers. Conclusion: A session with a clinical geneticist covering all reproductive options for patients in early adult life is a relevant part of the clinical management of patients with MEN 2A, and other patients with hereditary cancer predisposition syndromes.

Abstract
Scarce data are available on the quality of life and psychosocial distress of patients with multiple endocrine neoplasia type 2 (MEN2), a genetic cancer syndrome caused by RET germline mutations. Carriers of RET mutations can face several challenges, including fear for the future, guilt for transmission of a germline mutation to an offspring, side effects of cancer treatment, coping behaviors in the face of a chronic and frequently incurable cancer, and difficulties in access to adequate health care. We have addressed the effects of genetic testing on the quality of life of patients with MEN2 and the lifelong physical and psychosocial challenges experienced by these patients. We have also suggested strategies to minimize the burden of living with this chronic condition and the perspectives on future studies to improve the health-related quality of life of the patients.

Abstract
In this study we tested the associations of four high-order values (openness to change, self-transcendence, conservation, and self-enhancement, devised according to Schwartz’s model) and secularism of state with individuals’ attitude towards pre-implantation genetic diagnosis of embryos. Moreover, we tested the mediating effects of secularism of state on the relationship between values and attitude towards this issue related to embryos. Participants were 289 Spaniards who completed a questionnaire. Results showed that attitude towards pre-implantation genetic diagnosis was negatively affected by conservation and positively by self-transcendence. Moreover, results indicated that attitude towards a secular state positively correlates with attitude towards pre-implantation genetic diagnosis. Finally, results showed that secularism mediated the effects of conservation and self-transcendence, but not the effect of openness to change and self-enhancement on attitude towards pre-implantation genetic diagnosis. Taken together, results of this study suggest that people adopting values emphasizing the defence of the tradition reject pre-implantation genetic diagnosis because they want state laws to represent religious traditional values; on the other hand, people endorsing values emphasising the welfare of all accept pre-implantation genetic diagnosis because they want state laws to be free from religious values.

Abstract
INTRODUCTION Pancreas, parathyroid, and pituitary, are referred to as the "3 Ps" of MEN1. The time has come to move beyond those Ps and begin to discuss (1) prediction, (2) pausing progression, and (3) prevention of MEN1. METHODS In preparation for the International Association of Endocrine Surgeons State of the Art address, updates and uncertainties of MEN were reviewed. This included a detailed examination of the MEN1 gene and the library of implicated mutations, exon sequencing databases and cell cycle pathways. Therapeutic options including radiofrequency ablation, systemic therapy, peptide receptor radionuclide therapy, immune checkpoint inhibitor mechanisms and preimplantation genetic testing were described. RESULTS Several key points included mutations in exon 2 are suspected of being associated with a higher rate of distant metastases, a higher rate of PNET development, and more aggressive disease. The suggestion that missense mutations involving loss of interaction with CHES1 (associated with DNA repair) correlates with more aggressive disease and is more closely associated with death related to PNET than to death from other causes was mentioned. For advanced NETs, optimism for agents under study include lanreotide, a long-acting somatostatin analog, and everolimus (Afinitor), a mammalian target of rapamycin (mTOR) inhibitor. The NETest shows the potential value of being a multidimensional tumor marker for response to therapy. Preimplantation genetic diagnosis (PGD) is applicable. CONCLUSION Adjunct modalities and determination of the effect of therapy for MEN1 is needed. Prediction through early detection of aggressive disease is an idea worth spreading. We are called us to engage with our patients about prevention, the only true cure.

Abstract
OBJECTIVE Reproductive decision making for couples with hereditary breast and ovarian cancer (HBOC) is complex and can result in decisional conflict or regret. This study investigated couples' support needs and aimed to identify vulnerable couples. Ultimately, we should strive to develop a clear standard of care guideline regarding reproductive decision support. METHODS Mixed methods were used for data collection. A focus group study was conducted among 18 couples (N = 35) with HBOC who had made a reproductive decision after reproductive counselling. Subsequently, 129 similar couples (N = 258) were invited to complete a cross-sectional survey based on the focus group study. RESULTS Clinical and practical aspects of reproductive counselling were positively evaluated in the focus group study, although couples indicated a need for additional support with emotional and social concerns in which their relationship, social environment, and the way they picture their desired family were key elements. The survey was completed by 86 participants. Making a reproductive choice was experienced as (very) difficult by 43%, and 69% showed a need for additional support during decision making. Younger participants and those who opted for a natural pregnancy experienced more difficulty with reproductive decision making, and partners showed a higher need for psychological support than carriers. CONCLUSIONS Couples with HBOC who need to make a reproductive decision have specific needs for guidance and support, of which the desired content and methods can vary. It is therefore important to identify vulnerable couples and to attune counselling to couples' needs.

Abstract
Inherited cardiomyopathies, including hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM), are the most common monogenic cause of cardiac disease and can rarely lead to sudden cardiac death (SCD). They are characterized by incomplete and age-dependent penetrance and are usually initially symptomatic in adulthood yet can present in childhood as well. Over 20 genes have been identified to cause HCM, and more than 40 genes are known to cause DCM. Genetic testing for these genes has been integrated into medical care; however, the psychological impact of genetic testing and the impact of the uncertainty that comes with receiving these results have not been well studied. This study surveyed 90 adult probands and relatives with a personal or family history of cardiomyopathy from a single hospital-based cardiac genetic program to determine the psychosocial impact of genetic testing for cardiomyopathies. Standardized psychological instruments including an adapted Multidimensional Impact of Cancer Risk Assessment (aMICRA), Impact of Event Scale (IES), and Satisfaction with Decision (SWD) scales were utilized. Patients with positive genetic test results had higher scores for intrusive thoughts, avoidance, and distress when compared to those with negative genetic test results and were also more likely to make or plan to make life changes because of the results of their genetic testing. Satisfaction with the decision to undergo genetic testing was similar regardless of genetic test results. The results of this study provide insight into the patient experience of genetic testing for cardiomyopathies and how these experiences are associated with genetic test results and cardiac history.

Abstract
Hereditary breast and ovarian cancer caused by a BRCA1/2 mutation is the most frequent indication for preimplantation genetic diagnosis (PGD) in the Netherlands. The extent to which involved professionals are informed about this option, however, is unclear. The few available international studies mostly represent a limited range of professionals, and suggest that their knowledge about PGD for hereditary cancer syndromes is sparse and referral for PGD is based on limited understanding. A cross-sectional survey assessing awareness, knowledge, acceptability and PGD-referral for BRCA was completed by 188 professionals involved in the field of breast and ovarian cancer or reproduction. One-half of professionals were aware of PGD for BRCA, and most had a low to moderate level of knowledge. A total of 86% considered PGD for BRCA acceptable and 48% had referred patients with BRCA for PGD. Awareness and knowledge was higher among professionals who worked at a university hospital (compared with a general hospital). Knowledge of PGD was positively associated with discussing and referring for PGD, and PGD acceptability was associated with previous awareness. Although PGD counselling is the primary responsibility of the geneticist, other involved professionals may be gatekeepers as patients rely on them for raising awareness and referral.

Abstract
Since the 1980s the genetic cause of many hereditary tumor syndromes has been elucidated. As a consequence, carriers of a deleterious mutation in these genes may opt for prenatal diagnoses (PND). We studied the uptake of prenatal diagnosis for five hereditary cancer syndromes in the Netherlands. Uptake for retinoblastoma (Rb) was compared with uptake for Von Hippel-Lindau disease (VHL), Li-Fraumeni syndrome (LFS), familial adenomatous polyposis (FAP), and hereditary breast ovarian cancer (HBOC). A questionnaire was completed by all nine DNA-diagnostic laboratories assessing the number of independent mutation-positive families identified from the start of diagnostic testing until May 2013, and the number of PNDs performed for these syndromes within these families. Of 187 families with a known Rb-gene mutation, 22 had performed PND (11.8%), this was significantly higher than uptake for FAP (1.6%) and HBOC (<0.2%). For VHL (6.5%) and LFS (4.9%) the difference was not statistically significant. PND for Rb started 3 years after introduction of diagnostic DNA testing and remained stable over the years. For the other cancer syndromes PND started 10-15 years after the introduction and uptake for PND showed an increase after 2009. We conclude that uptake of PND for Rb was significantly higher than for FAP and HBOC, but not different from VHL and LFS. Early onset, high penetrance, lack of preventive surgery and perceived burden of disease may explain these differences.

Abstract
STUDY QUESTION To what extent are BRCA mutation carriers and their partners in the Netherlands aware about preimplantation genetic diagnosis (PGD) and prenatal diagnosis (PND) as reproductive options and what is their attitude towards these options? SUMMARY ANSWER Awareness of PGD (66%) and PND (61%) among BRCA mutation carriers and their partners is relatively high and 80% and 26%, respectively, of BRCA carriers and their partners find offering PGD and PND for hereditary breast and ovarian cancer (HBOC) acceptable. WHAT IS KNOWN ALREADY Internationally, awareness of PGD among persons with a genetic cancer predisposition appears to be relatively low (35%) and although acceptability is generally high (71%), only a small proportion of mutation carriers would consider using PGD (36%). However, for HBOC, there are no studies available that investigated the perspective of individuals with a confirmed BRCA1/2 mutation and their partners about PGD and PND including demographic and medical correlates of awareness and acceptability. STUDY DESIGN, SIZE, DURATION A cross-sectional survey was completed by 191 participants between July 2012 and June 2013. Participants were recruited through patient organizations (88%) and the databases of two Clinical Genetics departments in the Netherlands (12%). PARTICIPANTS/MATERIALS, SETTING, METHODS Male and female BRCA carriers and their partners completed an online survey, which assessed demographic and medical characteristics, and awareness, knowledge, acceptability and consideration of PGD and PND as main outcomes. Correlations between demographic and medical characteristics and the main outcomes were investigated. MAIN RESULTS AND ROLE OF CHANCE The majority of respondents were female (87%), of reproductive age (86%) and about half reported a desire for a child in the future. About two-thirds (66%) were aware of PGD and 61% of PND for HBOC. PGD knowledge was moderate (5.5 on a 9-point scale) and acceptability of PGD and PND for HBOC was 80% and 26%, respectively. A minority would personally consider using PGD (39%) or PND (20%). Individuals with a higher educational level were more likely to be aware of PGD (P < 0.001) and PND (P < 0.001) and persons with a more immediate child wish were more often aware of PGD (P = 0.044) and had more knowledge about PGD (P = 0.001). PGD acceptability was positively associated with knowledge about PGD (P = 0.047), and PND acceptability was higher among partners in comparison to carriers (P = 0.001). Participants with a history of cancer and with a higher perceived seriousness of breast and ovarian cancer were more likely to consider using PGD (P = 0.003 and P < 0.001 respectively) or PND (P = 0.021 and P = 0.017 respectively). LIMITATIONS, REASONS FOR CAUTION The response rate (23%) of participants invited by the clinical genetics departments was low, probably related to a simultaneous study that used a similar recruitment strategy within the same target group, which may have resulted in selection bias. Moreover, PGD knowledge was measured with an instrument that is not yet validated since to date such an instrument is not available in the literature. Finally, the cross-sectional design of this study limits us from drawing any causal conclusions. WIDER IMPLICATIONS OF THE FINDINGS Improvement of information provision remains needed, in order to timely inform all couples with HBOC about the available reproductive options and enable them to make a balanced reproductive decision. This may limit the risk of negative psychological impact due to decisional conflict and possible regret.

Abstract
BACKGROUND Social media is increasingly being used as a means of recruiting participants, particularly for investigators whose areas of interest involve rare conditions or hard-to-reach populations. However, much of the literature to date has focused on paid advertisement recruitment. OBJECTIVE We used Lynch syndrome (LS), a rare hereditary cancer syndrome, as a model to demonstrate the successful partnership between researchers and a Web-based patient education and advocacy organization to facilitate participant recruitment. METHODS Recruitment was undertaken in partnership with Lynch Syndrome International (LSI), an advocacy organization with a strong social media presence. After LSI published our study information, participants followed up via email or phone call. Following prescreening and consent, interested and eligible participants were then sent a secure survey link. RESULTS Within 36 hours of a single Facebook post by the site administrators for LSI, over 150 individuals responded via phone or email. Sixty-five individuals were sent the survey link and 57 individuals completed the survey (88% response rate). Of note, these 57 individuals were geographically diverse within the Unites States, representing LS patients from 26 different states. CONCLUSIONS This approach has several advantages, including recruitment through a trusted source outside of a clinical setting, higher response rates, and cost-effectiveness with a small research team in a relatively short amount of time. Overall, social media recruitment with a trusted online partner can be highly effective in hard-to-reach clinical populations, such as patients with LS. However, this approach requires additional effort for eligibility screening.

Abstract
BRCA mutation carriers have a very high risk of breast and ovarian cancer by age 70, in the ranges 47%-66% and 40%-57%, respectively. Additionally, women with BRCA mutation-associated breast cancer also have an elevated risk of other or secondary malignancies. Fortunately, the breast and ovarian cancer outcome for BRCA1/2 mutation carriers is at least as good as for non-carriers with chemoprevention, prophylactic surgeries and appropriate use of therapies. Therefore, identification of those who might have a mutation is important so that genetic counseling, testing, screening and prevention strategies can be applied in a timely manner. This article reviews the impact of genetic testing in general, timing of genetic testing after diagnosis and prior knowledge of mutation status in BRCA carriers with newly diagnosed breast cancer. Additionally, risk-reducing surgeries including the prophylactic contralateral mastectomy, and bilateral salpingo-oophorectomy and the sensitivity of BRCA-defective breast cancer cell lines to differential chemotherapeutic agents will be discussed.

Abstract
Expanded genetic testing of BRCA mutations has led to identification of more reproductive-aged women who test positive for the mutation which might impact attitudes and decisions about relationships, childbearing and the use of preimplantation genetic diagnosis (PGD) and prenatal diagnosis (PND). A cross-sectional survey was administered to 1081 self-reported BRCA carriers to investigate how knowledge of BRCA status influences these issues. The mean age at BRCA test disclosure was 44 years and 36 % reported a personal history of cancer. Of 163 women who were unpartnered, 21.5 % felt more pressure to get married. Of 284 women whose families were not complete, 41 % reported that carrier status impacted their decision to have biological children. Women with a history of cancer were more likely to report that knowledge of BRCA+ status impacted their decision to have a child (OR 1.8, 95 % CI 1-3.2). Fifty-nine percent thought PGD should be offered to mutation carriers and 55.5 % thought PND should be offered. In conclusion, knowledge of BRCA status impacts attitudes regarding relationships and childbearing, and most carriers believe that PGD and PND should be offered to other carriers. This study suggests that BRCA carriers desire and would benefit from reproductive counseling after test disclosure.

Abstract
AIMS No recommendations currently exist regarding implementation of both prenatal diagnosis and preimplantation genetic diagnosis (PGD) for autosomal dominant polycystic kidney disease (ADPKD). This study evaluated attitudes in ADPKD patients with either chronic kidney disease (CKD) stages I-IV or end-stage renal failure (ESRF) toward prenatal diagnosis and PGD. METHODS Ninety-six ADPKD patients were recruited from an outpatient clinic, wards, and dialysis units. Thirty-eight patients had ESRF and 58 had CKD stages I-IV. Participants were given an information sheet on prenatal diagnosis and PGD and subsequently completed a questionnaire. RESULTS The median age of participants was 51.5 years. Seventeen percent of ADPKD patients with CKD and 18% of ADPKD patients with ESRF would consider prenatal diagnosis and termination of pregnancy for ADPKD. Fifty percent with CKD would have opted for PGD (or might consider it in the future) were it available and funded by the UK National Health Service, compared to 63% in the ESRF group (p = 0.33). Sixty-nine percent in the CKD group and 68% in the ESRF group believed that PGD should be offered to other patients. DISCUSSION There was a spectrum of attitudes among this cohort. A proportion of patients believe that PGD should be made available to prospective parents with this disease. The discrepancy between the low proportion (17% CKD, 18% ESRF) who would consider prenatal diagnosis and termination of pregnancy and the higher number who hypothetically express an intention or wish to access PGD (50% CKD and 63% ESRF) indicates far greater acceptability for diagnostic methods that occur before embryo implantation. It is not known how the development of methods to identify patients whose renal function is likely to decline rapidly and treatments altering the natural history of ADPKD will affect these attitudes.

Insogna IG, Ginsburg E. Transferring embryos with indeterminate PGD results: the ethical implications. FERTILITY RESEARCH AND PRACTICE 2016; 2:2. [PMID: 28620529 PMCID: PMC5424418 DOI: 10.1186/s40738-016-0014-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/07/2015] [Accepted: 01/21/2016] [Indexed: 11/24/2022]
Abstract
Background In vitro fertilization (IVF) and pre-implantation genetic diagnosis (PGD) are becoming increasingly common techniques to select embryos that are unaffected by a known genetic disorder. Though IVF-PGD has high success rates, 7.5 % of blastocysts have inconclusive results after testing. A recent case involving a known BRCA-1 carrier was brought before our Assisted Reproductive Technology Ethics Committee in order to gain a better appreciation for the ethical implications surrounding the transfer of embryos with indeterminate testing. The case presentation Thirty-nine year old G0 BRCA-1 carrier requiring IVF for male factor infertility. The couple elected for PGD to select against BRCA-1 gene carrier embryos. However, several embryos were returned with inconclusive results. The couple wished to proceed with the transfer of embryos with an unknown carrier status. The case was presented before our Assisted Reproductive Technology Ethics Committee. Conclusion Many considerations were explored, including the physician's duty to protect patient autonomy, the physician's duty to act in the best interest of the future child, and the physician's duty towards society. Transferring both embryos with unknown carrier status and known-carrier status was debated. Ultimately, the transfer of inconclusive embryos was felt to be ethically permissible in most cases if patients had been adequately counseled. However, the re-biopsy of embryos with inconclusive testing results was encouraged. The transfer of known-carrier embryos was felt to be unethical for certain disease-states, depending on the severity of illness and timing of disease onset. We strongly encourage physicians to create an action plan in advance with their patients, prior to testing, in the event that embryos are returned with inconclusive PGD results. The committee’s decision, though helpful in guiding practice, should not overshadow the individual physician-patient relationship, and the need for thorough counseling.

Abstract
Adolescents and young adults (AYA) with a cancer diagnosis or those at risk for cancer due to hereditary cancer syndromes may benefit from genetic counseling and testing not only to manage personal risk but also to address reproductive concerns, especially fertility. The opportunity for genetic counselors to provide important risk information is relevant to both the newly diagnosed as well as to unaffected carriers and survivors. However, genetic counselors may need additional training in reproductive options related to AYA cancer to provide this valuable counsel. This commentary uses hereditary breast and ovarian cancer syndrome as a model to highlight important considerations when discussing preimplanatation genetic diagnosis and prenatal diagnosis, particularly in the context of expanded testing for hereditary cancer risk including multigene panels or whole exome or whole genome sequencing. Other hereditary cancers are also addressed; however, less is known about the psychosocial and fertility concerns in these AYA populations. Additionally, we provide an overview of the concept of “oncofertility” - the linkage between cancer care and reproductive medicine that aims to expand the reproductive opportunities of cancer patients - and offer support for the expansion of guidelines to include genetic counselors in AYA cancer patients’ treatment planning related to reproductive health and fertility.

Abstract
Reproductive techniques such as prenatal diagnosis (PND) or preimplantation genetic diagnosis (PGD), although debated, are legally forbidden in France in case of Lynch syndrome. The preference of mutation carriers about their reproductive options is not systematically considered in France. We aimed to prospectively assess the reproductive preferences of mismatch repair mutation carriers consulting in our institution (2003-2010, n = 100). We also considered the short- and long-term post-disclosure psychological impact using the Impact of Events Scale-Revised questionnaire to measure the prevalence of posttraumatic stress disorder (PTSD) in those patients. Complete data were obtained for 34 respondents (17 males, 17 females, median age of 33.5 years [22-59]). Seventeen respondents (57 %) preferred spontaneous natural conception versus 28 % and 35 % choosing PND and PGD, respectively. At results disclosure, respondents mainly explained their distress by fear of premature death (43 %) and transmitting mutated genes (42 %). One year later, this last fear remained predominant in 55 % of subjects. None of the main socio-demographical, psychological or medical variables (including fear of transmitting mutations) was significantly associated with the reproductive preferences. Results disclosure had a real and time-decreasing psychological impact on mutation carriers. Reproductive techniques, expected to decrease the hereditary risk, were not significantly preferred to natural conception.

Abstract
INTRODUCTION Lynch syndrome is the most common hereditary colorectal cancer syndrome, conferring a heightened risk not only of colon cancer but also of various extracolonic tumors. Studies in hereditary breast cancer have shown a negative psychological impact for patients testing positive for BRCA1 or BRCA2 mutations, but there is a paucity of literature looking at psychosocial impact of LS testing for probands and families. METHODS A literature search of PubMed English-language articles was performed using the keywords "Lynch syndrome" combined with "psychological impact," "depression," and "anxiety." RESULTS Lynch syndrome mutation carriers, whether or not they have had cancer, suffer a transient increase in depression and anxiety scores post-disclosure, which seem to normalize by 6-12 months. Younger patients with higher colorectal cancer risk perception, higher education level, married, and employed are more likely to accept genetic testing. Major motivators for testing are predicting one's own risk of cancer and risk to offspring. Carrier status influences family planning, and there is growing interest for preimplantation genetic diagnosis. CONCLUSIONS Psychosocial ramifications of LS mutation positivity need to be explored further.

Abstract
BACKGROUND Lynch syndrome (LS; hereditary nonpolyposis colorectal cancer) is a common cause of hereditary colorectal cancer (CRC). CRC is the most common cancer diagnosed among males in Saudi Arabia but to the authors' knowledge there is a lack of data regarding the prevalence of LS in patients with CRC. There currently are no clear guidelines for the selection criteria for these patients to screen for LS. METHODS A comprehensive molecular characterization was performed in a cohort of 807 CRC cases by immunohistochemical and microsatellite analysis using polymerase chain reaction. BRAF mutation screening, high CpG island methylator phenotype, and analysis for germline mutations were performed in 425 CRC samples. These were all high microsatellite instability (MSI-H) samples (91 cases), all low MSI samples (143 cases), and selected cases from the microsatellite stable group (191 cases) that met revised Bethesda guidelines. RESULTS Polymerase chain reaction identified 91 MSI-H cases (11.3%) and sequencing revealed mismatch repair germline mutations in 8 CRC cases only. Of the total of 807 CRC cases, these 8 cases (0.99%) were MSI-H, met the revised Bethesda guidelines, and did not harbor BRAF mutations. CONCLUSIONS The results of the current study confirmed cases of LS in approximately 1.0% of CRC samples and reflects the efficacy of screening among MSI-H cases that lack BRAF mutations. This comprehensive study from Saudi Arabia will help in implementing a universal screening/reflex testing strategy in a clinical setting in Saudi Arabia and in conducting a national screening program that benefits both patients and their relatives.

Abstract
Cancer genetic testing is surrounded by myriad ethical, legal, and psychosocial implications which are being revisited as testing expands into an everyday practice and into more complicated areas like whole exome and direct-to-consumer testing. We chose to survey cancer genetic counselors and physicians from a wide range of non-genetics specialties to determine what they would do if faced with the complex decisions associated with cancer genetic testing, how their views compare, and how they align with current guidelines and data. Genetic counselors were significantly more likely than non-genetics physicians to bill their insurance for testing (94.9 vs. 86.8 %; p = 0.001) and purchase life insurance before testing (86.6 vs. 68.6 %; p = 0.000) and were less likely to use an alias (3.2 vs. 13.2 %; p = 0.000) or order testing on their own DNA (15.3 vs. 24.2 %; p = 0.004). They were also less likely to test their minor children (0.9 vs. 33.1 %; p = 0.000) or test their children without their knowledge and consent/assent (1.4 vs.11.5 %; p = 0.000). The results of our study indicate that there is wide variation regarding what clinicians predict they would do in the areas of ethical, legal and psychosocial issues in cancer genetic testing. Cancer genetic counselors' choices are more aligned with professional guidelines, likely due to their experience in the field and awareness of current guidelines. These data are a starting point for a broader discussion of who should offer cancer genetic counseling and testing to patients, particularly as the complexity of the available testing options and associated issues increase with whole exome sequencing.
