Abstract
Hereditary Cancer makes up around 5-10% of all cancers. It is important to diagnose hereditary cancer in a timely fashion, as not only do patients require long-term care from a young age, but their relatives also require management. The main approach to capture at-risk relatives is cascade testing. It involves genetic testing of relatives of the first detected carrier of a pathogenic variant in a family i.e. the proband. The current standard of care for cascade testing is a patient-mediated approach. Probands are then advised to inform and encourage family members to undergo genetic testing. In Singapore, cascade testing is inefficient, around 10-15%, lower than the 30% global average. Here, we describe the cascade testing process and its effort to increase testing in Singapore. Precision Health Research, Singapore (PRECISE), was set up to coordinate Singapore's National Precision Medicine strategy and has awarded five clinical implementation pilots, with one of them seeking to identify strategies for how cascade testing for hereditary cancer can be increased in a safe and cost-efficient manner. Achieving this will be done through addressing barriers such as cost, manpower shortages, exploring a digital channel for contacting at-risk relatives, and getting a deeper insight into why genetic testing gets declined. If successful, it will likely result in care pathways that are a cost-effective public health intervention for identifying individuals at risk. Surveillance and management of those unaffected at-risk individuals, if caught early, will result in improved patient outcomes, and further reduce the healthcare burden for the economy.

Uptake of BRCA1/BRCA2 predictive genetic testing in an Irish population is low: a missed opportunity. Ir J Med Sci 2023; 192:1607-1611. [PMID: 36260241 DOI: 10.1007/s11845-022-03176-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 09/26/2022] [Indexed: 11/05/2022]
Abstract
INTRODUCTION Predictive testing for BRCA1 or BRCA2 allows at-risk individuals to engage with appropriate screening and treatment services if a pathogenic mutation is identified. Previous studies have shown uptake of predictive testing to most commonly range between 20% and 40% (Table 2). This represents a missed cancer prevention opportunity. Possible explanations for this low uptake include lack of disclosure of at-risk status to relatives, lack of awareness of cancer genetics services, or patient preference. The goal of the current study was to investigate the uptake of BRCA1 or BRCA2 predictive testing in an Irish population. METHODS We performed a multicentre, retrospective analysis of 63 pedigrees from two Irish tertiary referral hospitals over a five-year period (2012-2017). Family pedigrees were reviewed to identify at-risk family members eligible for predictive BRCA1 or BRCA2 mutation testing as per international guidelines, and testing rates were determined. RESULTS A total of 1048 eligible individuals were identified, 318 (30.4%) proceeded to BRCA1 or BRCA2 germline testing including [215 (37.5%) females and 99 males (21.5%)]. Women were significantly more likely to test than men (T = 3.7, p < .0002). Uptake of testing was significant higher amongst first-degree relatives 45% (150/323) compared to 20% (50/258) amongst second degree relatives, and 10 % (33/317) amongst more distant relatives (F = 25.32, p < 0.00001). CONCLUSIONS Uptake of BRCA1 OR BRCA2 mutation testing in Ireland is suboptimal, particularly amongst Irish males and distant relatives. Further research is needed to identify strategies which may improve uptake within current legal and ethical frameworks.

Relatives from Hereditary Breast and Ovarian Cancer and Lynch Syndrome Families Forgoing Genetic Testing: Findings from the Swiss CASCADE Cohort. J Pers Med 2022; 12:jpm12101740. [PMID: 36294879 PMCID: PMC9605198 DOI: 10.3390/jpm12101740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 10/11/2022] [Accepted: 10/13/2022] [Indexed: 11/17/2022] Open
Abstract
Cascade genetic testing of relatives from families with pathogenic variants associated with hereditary breast and ovarian cancer (HBOC) or Lynch syndrome (LS) has important implications for cancer prevention. We compared the characteristics of relatives from HBOC or LS families who did not have genetic testing (GT (−) group) with those who had genetic testing (GT (+) group), regardless of the outcome. Self-administered surveys collected cross-sectional data between September 2017 and December 2021 from relatives participating in the CASCADE cohort. We used multivariable logistic regression with LASSO variable selection. Among n = 115 relatives who completed the baseline survey, 38% (n = 44) were in the GT (−) group. Being male (OR: 2.79, 95% CI: 1.10–7.10) and without a previous cancer diagnosis (OR: 4.47, 95% CI: 1.03–19.42) increased the odds of being untested by almost three times. Individuals from families with fewer tested relatives had 29% higher odds of being untested (OR: 0.71, 95% CI: 0.55–0.92). Reasons for forgoing cascade testing were: lack of provider recommendation, lack of time and interest in testing, being afraid of discrimination, and high out-of-pocket costs. Multilevel interventions designed to increase awareness about clinical implications of HBOC and LS in males, referrals from non-specialists, and support for testing multiple family members could improve the uptake of cascade testing.

Patient-reported anticipated barriers and benefits to sharing cancer genetic risk information with family members. Eur J Hum Genet 2022; 30:53-61. [PMID: 33867528 PMCID: PMC8738729 DOI: 10.1038/s41431-021-00890-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 03/22/2021] [Accepted: 04/02/2021] [Indexed: 01/03/2023] Open
Abstract
While prior studies have largely focused on family communication of diagnostic single-gene test results or specific types of cancer testing results, far less work has investigated family communication of cancer-related genetic results that include multi-gene panels, a broad array of cancer types/stages, and participants without family history of cancer. The study we report here examined individuals' anticipated barriers and benefits to sharing genetic information with family members. An 80+ gene panel was performed on participants recruited from Mayo Clinic, diagnosed with different cancer types, who did not have a family history suggestive of an inherited risk. Participants completed a 49-item survey before receiving genetic test results. Family variant testing was provided to family members at no cost, allowing factors influencing intent to share to be examined in the absence of financial burdens. In all, 1721 of 2984 individuals who received genetic testing completed the survey (57.7% completion rate). Participants' intent to share with parents, siblings, and children was inversely related to the number of anticipated barriers to sharing and directly related to the number of anticipated benefits to sharing. Of those participants who did not intend to share with parents, siblings, and adult children, 64.8%, 30.3%, and 67.6% reported that there were no barriers, while 17.1%, 24.5%, and 40.2.% reported there were no benefits. Findings indicate that barriers to sharing genetic information with family members vary across family member types, and an inability to identify at least one benefit of sharing with family members is a predictor of intent not to share.

Abstract
Purpose To examine the benefit of telehealth over current delivery options in oncology practices without genetic counselors. Methods Participants meeting cancer genetic testing guidelines were recruited to this multi‐center, randomized trial comparing uptake of genetic services with remote services (telephone or videoconference) to usual care in six predominantly community practices without genetic counselors. The primary outcome was the composite uptake of genetic counseling or testing. Secondary outcomes compare telephone versus videoconference services. Results 147 participants enrolled and 119 were randomized. Eighty percent of participants in the telehealth arm had genetic services as compared to 16% in the usual care arm (OR 30.52, p < 0.001). Five genetic mutation carriers (6.7%) were identified in the telehealth arm, compared to none in the usual care arm. In secondary analyses, factors associated with uptake were lower anxiety (6.77 vs. 8.07, p = 0.04) and lower depression (3.38 vs. 5.06, p = 0.04) among those who had genetic services. There were no significant differences in change in cognitive or affective outcomes immediately post‐counseling and at 6 and 12 months between telephone and videoconference arms. Conclusion Telehealth increases uptake of genetic counseling and testing at oncology practices without genetic counselors and could significantly improve identification of genetic carriers and cancer prevention outcomes.

Communication of genetic information to at-risk relatives during the multidisciplinary monitoring of vascular Ehlers-Danlos syndrome in a French referral clinic. J Genet Couns 2020; 29:828-837. [PMID: 31903687 DOI: 10.1002/jgc4.1211] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2019] [Revised: 12/09/2019] [Accepted: 12/12/2019] [Indexed: 11/10/2022]
Abstract
Vascular Ehlers-Danlos syndrome (vEDS) is a rare inherited disorder leading to arterial, digestive, and uterine complications due to pathogenic COL3A1 variants. Identification of causal variants allows family screening, provided that relatives have previously been informed, according to a 2013 French Decree. The aims of our study were to assess the communication of genetic information to at-risk relatives, the impact of diagnosis disclosure and to highlight a possible link between the experience of vEDS patients and ability to communicate about genetic information. A total of n = 51 vEDS adult probands answered a questionnaire during a clinical visit. Communication to relatives was considered effective if the proband gave information to some or all first-degree relatives and considered easily achieved if it was disclosed to all relatives less than a month after the diagnosis and without difficulty. Personal and family vEDS experiences of probands were also assessed. Effective communication of information to relatives was remarkably high (98%). Siblings were the most frequently informed relatives (82%). Women informed their at-risk relatives of genetic family screening faster (p = .006) and easier (p = .004) than men. There was no difference in the disclosure of information to relatives before and after 2013 in our multidisciplinary clinic. Regarding the lived experience of vEDS patients, they felt anxious (78%) at diagnosis disclosure but also considered this diagnosis as an opportunity to start a medical follow-up (82%) putting an end to diagnosis delay. Our findings highlight for the first time that the ability to easily inform at-risk first-degree relatives is related to the relief felt during vEDS-positive diagnosis disclosure (p = .04). In order to improve the communication of genetic information to relatives, we believe that psychological support should systematically be part of the multidisciplinary monitoring, just as medical follow-up and genetic counseling.

Abstract
Polygenic risk scores (PRSs) are increasingly being implemented to assess breast cancer risk. This study aimed to assess and determine factors associated with uptake of PRS among women at increased risk of breast cancer for whom genetic testing to date had been uninformative. Participants were recruited from the Variants in Practice study from which breast cancer PRS had been calculated. Four hundred women were notified by letter of the availability of their PRS and invited to complete a self-administered survey comprising several validated scales. Considering non-participants, uptake of PRS was between 61.8% and 42.1%. Multivariate logistic regression identified that women were more likely to receive their PRS if they reported greater benefits (odds ratio [OR] = 1.17, P = .011) and fewer barriers to receiving their PRS (OR = 0.80, P = .007), had completed higher level education (OR = 3.32, P = .004), and did not have daughters (0.29, P = .006). Uptake of breast cancer PRS varied according to several testing- and patient-related factors. Knowledge of these factors will facilitate the implementation of polygenic testing in clinical practice and support informed decision making by patients.

Abstract
Cascade testing for cancer predisposition offers a highly efficient and cost-effective method for identifying individuals at increased risk for cancer, in whom targeted interventions can often improve survival. The aim of this study was to determine the impact of free cascade testing on uptake and identify other associated factors. Demographic and clinical data were gathered prospectively for 183 probands found to have a pathogenic variant associated with cancer predisposition and their 826 first-degree relatives (FDRs). The provision of free cascade testing was significantly associated with uptake (21.6% vs 6.1%; χ 2, P < 0.001). Relationship type between FDR and proband and FDR age also demonstrated significant associations, suggesting greater engagement amongst younger generations. Overall, 29.0% (53/183) of families had at least 1 FDR who underwent cascade testing. Of these families, 67.9% (36/53) had an uptake rate of at least 40.0%. Cost is a significant barrier to cascade testing uptake in Singapore. Tailored interventions targeting underrepresented groups and genetic counseling approaches supporting family communication and decision-making are necessary.

Abstract
OBJECTIVES The aim of this study was to demonstrate the utility of a comprehensive program involving management-based evidence, telemedicine, and patient navigation to provide genetic counseling services for patients with ovarian and breast cancer across a geographically large health care system. METHODS We identified all patients with newly diagnosed ovarian and breast cancer in our health care system from January 2013 to December 2015 through the cancer registry. Referral characteristics and testing outcomes were recorded for each year and compared using the χ or Fisher exact test. RESULTS Because the implementation of this program, the number of new ovarian cancer cases remained constant (109-112 cases/year) but patients referred for genetic counseling increased annually from 37% to 43% to 96% (P < 0.05). The percentage of ovarian cancer patients who underwent genetic testing increased annually from 24% to 27% to 53% (P < 0.05). The number of new breast cancer patients was constant (1543-1638 cases/year). The percentage of patients with triple negative breast cancer referred for genetic counseling rose from 69% in 2013 to 91% in 2015; the percentage of patients who underwent testing increased annually from 59% to 86% (P < 0.05). Of women with breast cancer diagnosed at less than 45 years of age, 78% to 85% were referred for genetic counseling across this period; the percentage of patients who underwent testing increased annually from 66% to 82% (P < 0.05). Patient navigation was initiated and was available to all patients in the system during this period. Telemedicine consults were performed in 118 breast/ovarian patients (6%) during this period. CONCLUSIONS A comprehensive program may improve access to effective genetic counseling services in patients with ovarian and breast cancer despite geographic barriers.

Abstract
PURPOSE This study aimed to evaluate predictors of testing uptake among unselected breast cancer patients who were offered germline BRCA1/2 testing in a prospective study. METHODS Pretest information was provided by a standardized invitation letter instead of in-person counseling. Data was abstracted from medical records. Using multivariate logistic regressions, predictors of testing uptake were analyzed. RESULTS The overall uptake of testing was 67% (539 of 805 patients). Low uptake rates were found for patients aged ≥80 years (33%), and patients born outside of Europe (37%). In adjusted analysis, age ≥80 years (odds ratio [OR] 0.10; P = 0.002), psychiatric disorders (OR 0.46; P = 0.006), occupation requiring at least 3 years of university or college education (OR 2.03; P = 0.003), and breast cancer or ovarian cancer in first-degree or second-degree relatives (OR 1.66; P = 0.02) were independently associated with uptake of BRCA1/2 testing. Somatic comorbidity in patients aged <70 years was associated with lower testing uptake. CONCLUSION Testing uptake varies across different subgroups according to patient-related factors that are readily available in the medical records. Knowledge about these factors enables health care professionals to identify patients who are less likely to pursue genetic testing.

Previous research has explored reasons for declining genetic testing and participation in genetic studies; however, there is a dearth of literature regarding why potential participants decline participation in GS research, and if any of these reasons are unique to GS. This knowledge is essential to promote informed decision-making and identify potential barriers to research participation and clinical implementation. We aggregated data from seven sites across the National Institutes of Health's Clinical Sequencing Exploratory Research (CSER) consortium on each project's procedures for recruitment, and rates of and reasons for decline. Data were analyzed using descriptive statistics. The decline rate for enrollment at the seven CSER sites ranged from 12 to 64% (median 28%) and varied based on age and disease status. Projects differed in their protocols for approaching potential participants and obtaining informed consent. Reasons for declining GS research were reported for 1088 potential participants. Commonly cited reasons were similar to those reported for clinical single gene testing and non-GS genetic research. The most frequently cited reason for decline was study logistics (35%); thus, addressing logistical barriers to enrollment may positively impact GS study recruitment. Privacy and discrimination concerns were cited by 13% of decliners, highlighting the need for researchers and providers to focus educational efforts in this area. The potential psychological burden of pursuing and receiving results from GS and not wanting to receive secondary findings, a concern specific to GS, have been cited as concerns in the literature. A minority of potential participants cited psychological impact (8%) or not wanting to receive secondary findings (2%) as reasons for decline, suggesting that these concerns were not major barriers to participation in these GS studies. Further research is necessary to explore the impact, if any, of different participant groups or study protocols on rates of decline for GS studies. Future studies exploring GS implementation should consider using standardized collection methods to examine reasons for decline in larger populations and more diverse healthcare settings.

Abstract
AIMS To explore the views of the Belgian public on various topics surrounding genetics and genetic testing (GT). MATERIALS AND METHODS A written questionnaire was administered to visitors of the annual cartoon festival in Knokke-Heist, Belgium, during the summer of 2014. The main theme of the festival was challenges and progress in human genetics and it was attended by more than 100,000 visitors. RESULTS The survey was completed by 1182 respondents, resulting in a demographically diverse sample with a mean age of 48.5 years. Our respondents expressed moderate interest in predictive GT, with 39.1% willing to learn about their predisposition to diseases through GT and 49.5% indicating interest in getting tested exclusively for treatable/preventable diseases. We observed higher interest in GT for reproductive purposes, such as preconception screening for recessive disorders (53.8%) and prenatal GT (60.7%). A substantial minority (46.4%) of the respondents were worried that GT could further stigmatize people with disabilities, while 39.7% believed that carrier screening for recessive diseases would lead to an inferior image of people affected by them. CONCLUSION Paying due attention to the attitudes, beliefs, and concerns of the general public is important to ensure ethically sound and socially acceptable implementation of new genetic technologies.

Abstract
Current genetic counselling practice for Lynch syndrome (LS) relies on diagnosed index patients to inform their biological family about LS, referred to as the family-mediated approach. The objective of this study was to evaluate this approach and to identify factors influencing the uptake of genetic testing for LS. In 59 mutation carriers, 70 non carriers and 16 non-tested relatives socio-demographic characteristics, family communication regarding LS, experiences and attitudes towards the family-mediated approach and motivations for genetic testing, were assessed. The majority of all respondents (73 %) were satisfied with the family-mediated approach. Nevertheless, 59 % of the respondents experienced informing a family member and 57 % being informed by a family member as burdensome. Non-tested differed from tested respondents, in that they were younger, less closely related to the index patient and a lower proportion had children. The most important reasons for declining genetic testing were (1) anticipating problems with life insurance and mortgage, (2) being content with life as it is, and (3) not experiencing any physical complaints. In conclusion, the majority of respondents consider the current family-mediated information procedure acceptable, although the provision of information on LS by relatives may be burdensome. Special attention should be paid to communication of LS to more distant relatives.

Abstract
Over 100,000 individuals living in Ireland carry a mutated gene for an inherited cardiac condition (ICC), most of which demonstrate an autosomal dominant pattern of inheritance. First-degree relatives of individuals with these mutations are at a 50 % risk of being a carrier: disclosing genetic information to family members can be complex. This study explored how families living in Ireland communicate genetic information about ICCs and looked at the challenges of communicating information, factors that may affect communication and what influence this had on family relationships. Face to face interviews were conducted with nine participants using an approved topic guide and results analysed using thematic analysis. The participants disclosed that responsibility to future generations, gender, proximity and lack of contact all played a role in family communication. The media was cited as a source of information about genetic information and knowledge of genetic information tended to have a positive effect on families. Results from this study indicate that individuals are willing to inform family members, particularly when there are children and grandchildren at risk, and different strategies are utilised. Furthermore, understanding of genetics is partially regulated not only by their families, but by the way society handles information. Therefore, genetic health professionals should take into account the familial influence on individuals and their decision to attend genetic services, and also that of the media.

Abstract
The study of human genetics has provided substantial insight into cancer biology. With an increase in sequencing capacity and a reduction in sequencing costs, genomics will probably transform clinical cancer genetics. A heritable basis for many cancers is accepted, but so far less than half the genetic drivers have been identified. Genomics will increasingly be applied to populations irrespective of family history, which will change the framework of phenotype-directed genetic testing. Panel testing and whole genome sequencing will identify novel, polygenic, and de-novo determinants of cancer risk, often with lower penetrance, which will challenge present binary clinical classification systems and management algorithms. In the future, genotype-stratified public screening and prevention programmes could form part of tailored population risk management. The integration of research with clinical practice will result in so-called discovery cohorts that will help identify clinically significant genetic variation.

Abstract
Little is known about the process of psychosocial adaptation to familial risk in tested and untested individuals at increased familial risk of cancer. This paper presents findings from a qualitative study of 36 women participating in the Kathleen Cuningham Consortium for Research into Familial Breast cancer (kConFab) Psychosocial study. Facilitators and challenges in psychosocial adaptation were identified through semi-structured interviews. The women, who were either tested (carriers or non-carriers of breast cancer susceptibility mutations) or untested (ineligible for testing or eligible but delayed or declined testing), described personal, support network and healthcare characteristics that impacted on the adaptation process. Challenges in one domain could be overcome by facilitators in other domains and key differences relating to whether women had undergone testing, or not, were identified. Tested and untested women with an increased familial risk of breast cancer may benefit from support tailored to their mutation testing status in order to enhance adaptation.

Abstract
As genetic testing for hereditary cancer syndromes has transitioned from research to clinical settings, research regarding its accompanying psychosocial effects has grown. Men and women being tested for hereditary cancer syndromes may experience some psychological distress while going through the process of testing or after carrier status is identified. Psychological distress appears to decrease over the course of the first year and it is typically not clinically significant. Longer term studies show mixed results with some mutation carriers continuing to experience elevated distress. Baseline distress is the greatest risk factor for both immediate (weeks-12 months) and long-term psychological distress (18 mo-8 years post genetic testing). In addition to baseline psychological distress, other risk factors can be identified to help identify individuals who may need psychosocial interventions during the genetic testing process. The challenges of providing clinical care to the growing population of individuals identified to be at increased risk for heritable cancers present opportunities for research and new models of care.

Abstract
Genetic testing is increasingly available in medical settings and direct-to-consumer. However, the large and growing literature on genetic testing decisions is rife with conflicting findings, inconsistent methodology, and uneven attention across test types and across predictors of genetic testing decisions. Existing reviews of the literature draw broad conclusions but sacrifice nuanced analysis that with a closer look reveals far more inconsistency than homogeny across studies. The goals of this paper are to provide a systematic review of the empirical work on predictors of genetic testing decisions, highlight areas of consistency and inconsistency, and suggest productive directions for future research. We included all studies that provided quantitative analysis of subjective (e.g., perceived risk, perceived benefits of testing) and/or objective (e.g., family history, sociodemographic variables) predictors of genetic testing interest, intentions, or uptake, which produced a sample of 115 studies. From this review, we conclude that self-reported and test-related (as opposed to disorder-related or objective) predictors are relatively consistent across studies but that theoretically-driven efforts to examine testing interest across test types are sorely needed.

Abstract
AIMS The majority of hereditary breast and ovarian cancers are associated with highly penetrant mutations in two genes: BRCA 1 and 2. Our aim was to investigate the prevalence and types of BRCA mutations in patients from the West of Ireland. METHODS A retrospective cohort study was undertaken that included all patients from the counties, Mayo, Sligo, Galway, Roscommon, and Clare, who were referred to the National Centre for Medical Genetics (NCMG) for testing for mutations in BRCA 1 or 2 between 2000 and 2010. Data including age, symptoms, family history, Manchester score, and test results were recorded and analysed using SPSS. RESULTS The NCMG received 380 referrals from the Western seaboard, including 148 for diagnostic testing and 232 for predictive evaluation. Sixty-five patients did not attend for assessment. Two hundred and fifty-six patients fulfilled criteria for genetic counselling, which was accepted by 184, of whom 127 proceeded to testing. Predictive tests were more often declined than diagnostic [41 (46 %) vs. 16 (17 %)]. Ten mutations in BRCA 1 were identified in 20 patients (15 families), including Exon 1-23del (3 families); Exon 14-20del (2 families) and E143X (2 families). Six mutations in BRCA 2 were identified in 15 patients (12 families) including 8525delC (n = 2 families) and 8205-1G>C (n = 3 families). Patients with positive results had significantly higher Manchester scores than those with negative tests [median 25.5 (12-48) vs. 20 (8-37), p = 0.042, Mann-Whitney U test]. CONCLUSION To identify patients with highly penetrant variants, referrals should be made with strict adherence to guidelines. Counselling should be individualised to counteract intrinsic psychological barriers to testing.

Abstract
Limited data suggest that enhanced self-knowledge from genetic information related to non-medical traits can have a positive impact on psychological well-being. Deaf individuals undertake genetic testing for deaf genes to increase self-knowledge. Because deafness is considered a non-medical trait by many individuals, we hypothesized that deaf individuals receiving a genetic explanation for why they are deaf will experience increased psychological well-being. We report results from a prospective, longitudinal study to determine the impact of genetic testing (GJB2, Cx26; GJB6, Cx30) on perceived personal control (PPC), anxiety, and depression in deaf adults (N = 209) assessed following pre-test genetic counseling as well as 1-month and 6-months following test result disclosure. Participants were classified as Cx positive (n = 82) or Cx negative/inconclusive (n = 127). There was significant evidence for Cx group differences in PPC and anxiety over time (PPC: Cx group*time interaction p = 0.0007; anxiety: Cx group*time interaction p = 0.002), where PPC scores were significantly higher, and anxiety scores were significantly lower for the Cx positive group relative to the negative/inconclusive group following test result disclosure. Compared to pre-test, PPC scores increased at 1-month (p = 0.07) and anxiety scores decreased at 6-months (p = 0.03) for the Cx positive group. In contrast, PPC scores decreased (p = 0.009, p < 0.0001) and anxiety scores increased (p = 0.09, p = 0.02) for the Cx negative/inconclusive group at 1- and 6-months post test result disclosure. Genetic testing for deaf genes affects the psychological well-being of deaf individuals. Increasing deaf adults' access to genetic testing may potentially enhance self-knowledge and increase psychological well-being for those who receive a genetic explanation, which could offer downstream health benefits.

Abstract
PURPOSE The Kathleen Cuningham Foundation Consortium for Research into Familial Aspects of Breast Cancer (kConFab) is a large-scale research study that notifies participants when new, personally relevant, information is discovered. In 2009, the (kConFab) instituted an intensive notification process to ensure at-risk individuals were effectively notified. This study (i) evaluated the impact of intensive notification on genetic testing uptake; (ii) identified those most likely to undergo testing postnotification; and (iii) identified those most likely to acknowledge that they had been notified. METHODS Clinical/demographic data were retrieved from the (kConFab) database. Logistic regression analyses were conducted to identify potential predictors of testing uptake and notification acknowledgment using IBM SPSS. RESULTS A total of 155 of 1,812 individuals underwent testing after standard notification (8.6%). In comparison, 23/291 individuals (7.9%) notified using the "intensive" approach underwent testing (χ(2) = 0.14; P = 0.71). After controlling for notification process, females and participants with a previous cancer were most likely to have undergone testing (P < 0.006). Older individuals (50+ years) were most likely to acknowledge they had been notified (P = 0.038). CONCLUSION Increasing the intensity of participant follow-up did not increase genetic testing uptake. The challenge to effectively notify participants, and increase the proportion whose risk is managed clinically, remains, particularly for males and individuals unaffected by cancer.Genet Med 2013:15(3):187-194.

Abstract
This study examines psychological determinants and effects of participating in genetic testing among persons diagnosed with or at risk for developing primary pulmonary arterial hypertension. Longitudinal data were drawn from orally administered surveys with 70 affected or at-risk individuals concerning their thoughts, feelings, and decision making about testing for mutations in BMPR2. Distress was measured by use of the Impact of Events Scale. Variations in tolerance for ambiguity were also examined. Although uptake of testing was low, as is common for incompletely penetrant mutations that lack clear therapeutic interventions, we found that those who participated in testing evidenced greater reduction in distress compared to those who had not participated in testing, irrespective of test result. No differences in tolerance for ambiguity by testing status were found. Participation in genetic testing, irrespective of test results, may be particularly beneficial to individuals who may have genetic mutations and who are experiencing high levels of distress.

Abstract
This study explored relationships between worry, perceived risk for breast cancer, consulting a genetic counselor, having genetic testing, and genetic risk for women whose mothers had breast cancer. Analyses involved data from a community-based phone survey of women whose mothers had breast cancer. Participants were categorized as having low, intermediate, or high genetic risk based on their reported family history, in accordance with an accepted classification scheme. The Lerman Breast Cancer Worry Scale measured worry, and participants reported their perceived lifetime likelihood of breast cancer, risk compared to others, and chance from 1 to 100. ANOVA, chi-square, and multiple regression analyses were conducted as appropriate. One hundred-fifty women participated. Mean age was 38 years, and 81% were Caucasian. Fifty-two women had low, 74 had intermediate, and 24 had high genetic risk for breast cancer. There were no significant differences in worry or perceived risk by hereditary risk category. Most high-risk women (91%) had not spoken with a genetic counselor, and no one had previous genetic testing. These findings suggest perceived risk, worry about breast cancer, and use of expert consultation do not match the genetic contribution to risk. There is a need for effectively stratifying and communicating risk in the community and providing tailored reassurance or referral for high-risk assessment.

Abstract
The use of mailed family history questionnaires (FHQs) has previously been established to be an effective method for obtaining family history information for the triage of patients for genetic counseling and genetic testing of hereditary breast and ovarian cancer syndrome; yet only 53% of patients complete their FHQ within 6 months from the date of mailing (Armel et al. Journal of Genetic Counseling, 18(4):366-378, 2009). Although literature exists evaluating why women may not attend genetic counseling, no data are currently available examining genetic risk or genetic testing eligibility in the population of patients not returning their FHQ (non-responders). Concern exists that if non-responders are not followed-up for the purpose of triage for genetic counseling, individuals at high-risk for a hereditary cancer syndrome may be missed. This article explores the demographics of the non-responder population to assess genetic risk estimates for mutations in the BRCA1 and BRCA2 genes and genetic testing eligibility as compared to a responder population of patients who completed a mailed FHQ. A total of 430 pedigrees were obtained, 215 from non-responders and 215 from responders. Results of this study indicate that 69% of non-responders were either unreachable by telephone (42%), declined an appointment (19%), or were previously seen in another center for a genetic counseling visit (8%). Additionally, results indicate that non-responders are less likely to be eligible for genetic testing (40%) as compared to responders (57%) (p = 0.0004). Together these data shed light on a population of patients for which limited information exists and suggest that we question how and to what extent clinics should pursue non-responders, particularly in light of global reductions in health care funding.

Abstract
Genetic testing for hereditary breast and ovarian cancer reveals significant risk information regarding one's chances of developing cancer that has potential implications for patients and their families. This study reports on the motivations and attitudes of index patients and their relatives towards genetic testing for hereditary breast and ovarian cancer. In total, 10 female index patients and 20 of their relatives were interviewed regarding their experiences of communicating genetic information within their families, and their motivations and attitudes towards genetic testing. The analysis found two types of 'family groups': groups strongly committed to genetic testing and groups uncertain about testing. Within committed family groups, index patients and their relatives felt obliged to be tested for others, leading some relatives to be tested without having fully thought through their decision or the implications of knowing their mutation status. These family groups also described considerations in relation to the value of testing for themselves. In family groups uncertain about testing, relatives had not attended for predictive testing, had postponed decision making until some point in the future or had expressed ambivalence about the value of testing for themselves. Results suggest the value of explicitly acknowledging motivations for genetic testing within the context of family obligations, relationships and communication, and the possible value of involving family members in genetic counselling and decision making from a family's first contact with genetic services.

Abstract
Discovery of mutations in the breast and ovarian cancer susceptibility genes BRCA1 and BRCA2 can have emotional consequences for both the tested individual and his or her relatives. This secondary analysis study investigated how BRCA testing impacts family dynamics and relationships. For the original study, a grounded theory inquiry, participants were recruited from a hereditary breast/ovarian cancer syndrome support website and open-ended interviews were performed asking about individual and family experiences after BRCA testing. All 12 participants whose interviews were included in the secondary analysis had a BRCA mutation. For the secondary analysis, thematic analysis was conducted and revealed three main themes characterizing the effect of BRCA testing on family relationships: 1. That the first in the family to have testing or seek genetic counseling takes on a special family role that can be difficult for them; 2. That discussions in the family often change; and 3. That individuals may feel more or less connected to certain family members. These changes seemed to relate to family cancer history, relationships, coping strategies, communication patterns, and mutation status. Genetic counselors might find it useful to explore these issues in order to prepare clients before BRCA testing and to support them through shifts in family dynamics after disclosure of results.

Abstract
Although the average blood lead level of 1-4-year-old children in Broken Hill has halved since 1991, about 1 in 5 still have blood lead levels higher than the national target (<10 microg/dL). The estimated proportion of children attending the Lead Clinic has declined, to approximately 42% in 2006, raising concern that some children with elevated blood lead levels may not be presenting, thus missing out on appropriate treatment and advice. The aim of this study was to describe patterns of attendance at the clinic as a first step to understanding what factors contribute to clinic attendance and non-attendance. Routinely collected data from the Lead Clinic database were used to describe the impact of factors such as child age, the lead-risk area in which they live, seasonal influences and specific promotional activities on clinic attendance rates from 1999 to June 2007. Estimates of the number of children living in each of the five lead-risk areas were derived from 2001 and 2006 census data and estimates of the number of children born to mothers resident in Broken Hill were derived from the Midwives Data Collection. Attendance rates declined by approximately one-third during the study period. Younger children, and those living closer to the central mining area, were more likely to attend for blood lead screening. Cohort analysis indicated cumulative attendance has declined, with children born in 2005 having a cumulative incidence at 18 months of age 5-10% lower than that for previous birth cohorts. The majority (54%) of children who developed a notifiable blood lead level (15 microg/dL) were first detected at 2 years of age or older, a number of whom (40%) had no recorded tests before the age of 2 years. The analysis has demonstrated the benefits of using an expanded set of performance indicators to monitor the blood lead screening programme. It provides valuable additional information about the reach of the programme. Next steps include seeking additional feedback from carers and the broader community, developing a strategy to increase screening and monitoring the effectiveness of efforts to reinvigorate the lead management programme.

Abstract
Despite expanding knowledge regarding the genetics of melanoma, there have been few attempts to define the psychosocial experiences of individuals with a family history of this disease. This study explored the ways in which individuals at varying levels of risk perceive, and respond to, melanoma. Forty semi-structured interviews were undertaken with affected (n = 20) and unaffected (n = 20) individuals with or without a family history of melanoma. Data were analysed for potential thematic differences between risk groups, genders, and intentions to pursue genetic testing for melanoma risk. Overall, participants with a family history were in acceptance of their increased risk status and had developed ways of coping without major disruption to their daily lives. However, some participants expressed ambiguity regarding the causes of melanoma and the effectiveness of health behaviours such as sun protection. Major thematic patterns identified for those intending to pursue genetic testing were: negative emotional associations with melanoma; an emphasis on screening and sun avoidance, but not sun protection; and heightened perceptions of personal susceptibility to melanoma. In contrast, thematic patterns identified for those likely to decline testing were: ready access to stories of melanoma survival; and an emphasis on the causal role of sun exposure, whilst still believing that genetic factors may contribute to melanoma susceptibility. Compared to males, females reported a greater tendency to completely avoid the sun in order to reduce their melanoma risk. The data provide preliminary evidence for the importance of identifying misconceptions that may impede informed decision-making about genetic testing for melanoma risk.

Abstract
We investigated the uptake of genetic testing by 54 families in South East Scotland with a BRCA1/2 mutation. At a median of 37 months since identification of the mutation, the overall rate of uptake of testing in 269 eligible family members was 32%. First-degree relatives were significantly (P<0.05) less likely to be referred for genetic counselling in more, compared to less, socioeconomically deprived families (46 versus 68%). Among relatives who attended for genetic counselling, females were more likely to be tested than males (76 versus 53%; P<0.05) and relatives with children more than those without children (82 versus 53%; P<0.001). Tested relatives were older than relatives who did not undergo testing (mean 41.9 versus 36.8 years, P<0.05) but did not differ in degree of relationship to the index case or in socioeconomic deprivation. Our results confirm the findings from other studies of substantially lower rates of uptake of genetic testing for BRCA1/2 mutations than anticipated in earlier predictions. Relatives in more socioeconomically deprived families were less likely to be referred for genetic counselling, which is a matter of concern. This may be partly the result of a lack of understanding of the testing process. Cascading currently does not work in breast cancer families and further work is required to investigate intrafamilial communication patterns, testing behaviour and counselling strategies.

Abstract
INTRODUCTION Although it is important that children at risk of developing elevated blood lead receive regular screening, attendance at screening programs is variable. A literature review was undertaken to better understand the factors that affect carers' decisions about whether or not to take their children for blood lead screening. METHOD Electronic databases (Medline, EMBASE, CINAHL, Psychinfo) were searched to identify relevant publications, supported by reviewing reference lists of identified articles and searching with internet-based search engines. RESULTS Thirty-four published studies dealing with blood lead screening rates were identified, of which only seven papers focused specifically on parent's attitudes to blood lead screening. The barriers to and enablers of screening for elevated blood lead levels appear to be similar to those identified for other screening programs. DISCUSSION It is recommended that attendance at screening be routinely monitored, and that where participation is suboptimal further research be undertaken, in close co-operation with affected communities or sub-groups, to determine how best to encourage screening and to protect children from lead. It is important to minimize stigma and to ensure, as far as possible, that practical barriers such as lack of transport do not restrict access to screening programs.

Abstract
Hereditary non-polyposis colorectal cancer (HNPCC) represents about 1-3% of all cases of colorectal cancer (CRC). The objectives of the study were to examine motivational factors, expectations and psychosocial functioning in a sample of CRC survivors undergoing genetic testing for HNPCC. A cross-sectional survey of 314 colorectal cancer patients recruited through a population-based colon cancer family registry was conducted. Motivations for genetic testing for hereditary cancer were similar to those of clinic-based samples of CRC patients and included learning of the increased risk to offspring and finding out if additional screening was needed. While age at diagnosis and sex were associated with psychological functioning, significant predictors of post-counseling distress were perceived lower satisfaction with social support, an escape-avoidant coping style and the anticipation of becoming depressed if a mutation was present. Most cancer survivors anticipated disclosing test results to relatives and physicians. Cancer survivors reported several motivations for genetic testing for HNPCC that varied by sex. A subgroup of survivors with lower satisfaction with social support and an escape-avoidant coping style were worried about the potential impact of genetic test results and demonstrated more distress following counseling. Findings have implications for future research and potential support needs during the genetic counseling and testing process.

Abstract
We conducted a psychological assessment during oncogenetic counseling for hereditary breast/ovarian cancer. Anxiety and depression were assessed with the HAD scale, and family functioning and satisfaction with FACES III. HAD was administered at baseline (t(1)), at risk communication (t(2)), at genetic test result communication, or at first surveillance in not tested subjects (t(3)); FACES III was administered at baseline only. We analysed a total of 185 questionnaires administered to the 37 subjects studied. Although not pathological, distress was significantly higher at t(2) and t(3) (p = 0.027 and p = 0.039, respectively). Health and marital status were significantly associated with distress. In a disease-free condition, anxiety was higher (p = 0.027) at t(2), and for single status, depression increased from t(1) to t(2) (p = 0.026). Families were perceived to be well functioning, and subjects were satisfied with their families. The data collected in this analysis could help to improve the quality of oncogenetic counselling in clinical practice.

Abstract
BACKGROUND Many African American men have two major risk factors for prostate cancer. By ethnicity alone, they have twice the risk of Euro-American men of developing prostate cancer. Having a family history (brother or father with prostate cancer) also doubles their risk. The major hypotheses tested in this study are that men with a family history perceive their risk to be higher, are more worried about getting prostate cancer, and are more likely to have used cancer screening tests than men without such a history. METHODS A sample of 208 African American men, ages 40 to 74 years, were recruited through relatives or friends whose prostate cancer diagnosis was reported to the California Cancer Registry during the years 1997 to 2001 and from churches and African American social groups. Following a screening interview to determine eligibility, 88 men with self-reported, first-degree family history of prostate cancer and 120 without such history were interviewed by telephone. Logistic regression was used to create models of perceived risk, prostate cancer worries, receipt of a digital rectal exam, and/or prostate-specific antigen (PSA) testing. RESULTS Men with a self-reported family history of prostate cancer did not perceive their risk as higher than men without a family history, nor did they report more cancer worries. They were more likely to report having a recent PSA test, but not a digital rectal exam. Having a higher than average perceived risk was associated with younger age, a college education, and lower mental well-being, and reporting more prostate cancer worries and being more likely to have had a recent PSA test. CONCLUSIONS Although there continues to be controversy about PSA testing, these data suggest that African American men at above-average risk are inclined to be screened.

Abstract
These cancer genetic counseling recommendations describe the medical, psychosocial and ethical implications of identifying at-risk individuals for hereditary breast and ovarian cancer (HBOC) through cancer risk assessment, with or without genetic susceptibility testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors' Familial Cancer Risk Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment as well as the professional expertise of genetic counselors with significant experience in education and counseling regarding hereditary breast and ovarian cancer. Critical components of the process include the ascertainment of medical and family histories, determination and communication of cancer risk, assessment of risk perception, education regarding the genetics of HBOC, discussion of molecular testing for HBOC if appropriate (including benefits, risks and limitations) and any necessary follow-up. These recommendations do not dictate an exclusive course of management or guarantee a specific outcome. Moreover, they do not replace the professional judgment of a health care provider based on the clinical situation of a client.

Abstract
Our study aimed to examine why individuals withdraw from genetic testing for breast and ovarian cancer susceptibility. We explored the characteristics of 334 individuals from high-risk breast and ovarian cancer families who declined genetic testing for BRCA1/2 mutations, when, and why they did so. Individuals who declined genetic testing were older, and a greater proportion had never developed breast or ovarian cancer. Fifty one per cent (51.1%) of individuals withdrew after the first genetic counseling session. Most of those who declined were afraid of the psychological effects of genetic testing (36.3%). The next most-cited explanations concerned logistic problems such as a limited ability to travel, lack of time, personal issues, advanced age, or health problems (21.7%). The third category included individuals who did not see any advantage in being tested (14.5%). Insurability was a concern (5.9%), mainly for men. Surprisingly, confidentiality was not a frequently reported issue (1.3%). Sixty eight per cent (68%) of individuals belonging to a family in which at least one individual has been tested withdrew after the presence of a deleterious BRCA1/2 mutation in a relative was disclosed, compared to 42% after the disclosure of a nonconclusive test result in at least one relative. Concern about the psychological effects of the result was still one of the major reasons. Several factors may influence an individual's decision to decline genetic testing; a greater understanding of these issues may help health professionals to better meet the needs and concerns of individuals from high-risk families, thus possibly improving their health outcomes.

Abstract
Many women who are offered BRCA genetic testing by genetics professionals do not have the test, possibly for financial reasons. We explored financial factors implicated in non-uptake of BRCA testing in women who had received genetic counseling in a clinical setting. Specifically, we described financial factors (affordability, health insurance, other) involved with BRCA testing; compared nonfinancial factors (disease, sociodemographic, risk assessment) in women who did not have BRCA testing (nontesters) with women who had the test (testers); showed associations of financial and nonfinancial factors with BRCA testing; and identified predictors of non-uptake of BRCA testing. The sample of 100 women (64 nontesters and 36 testers) completed an anonymous mailed survey on financial factors; 52 of the nontesters answered questions about nonfinancial factors. Testers had significantly better affordability and insurance coverage (p < 0.001), more diagnoses of breast or ovarian cancer (p < 0.05) and higher rates of receiving post-counseling risk estimates (p < 0.05), than nontesters. Non-uptake was 5.5-fold more likely in women that could not afford full or partial payment for the test and was 15.5-fold more likely in women that did not recall receiving risk estimates post-counseling. For many women having risk factors for breast/ovarian cancer, affordability of BRCA testing and insurance coverage for the test remain problematic. Post-counseling reminders of risk estimates may contribute to uptake of testing.

Abstract
PURPOSE This study is part of an ongoing National Cancer Institute multidisciplinary, etiologically-focused, cross-sectional study of Familial Testicular Cancer (FTC). The current report targets interest in clinical genetic testing for susceptibility to FTC. METHODS Demographics, knowledge, health beliefs, and psychological and social factors were evaluated as covariates related to interest in genetic testing. RESULTS The majority (66%) of 229 participants (64 affected men, 66 unaffected men, and 99 women) from 47 multiple-case FTC families expressed interest in having a genetic test within 6 months, should such a test become available. Interest was similar among the three subgroups mentioned above. Worries about insurance discrimination based on genetic test results were associated with a significantly lower interest in testing. Alternatively, participants were more likely to be interested in genetic testing if they were younger and had higher levels of family support, a physician's recommendation supporting testing, cancer distress, and a need for information to inform the health care of their children. CONCLUSIONS This study reveals social and relationship factors that FTC survivors and their relatives considered important when contemplating the use of new genetic technologies. This is the first study describing hypothetical interest in genetic testing for familial testicular cancer.

Abstract
PURPOSE Examine young adults' attitudes about HFE genotyping. METHODS 121 college students read about hemochromatosis, transferrin saturation measurement (iron test), and HFE genotyping. Interest in testing and knowledge and attitudes about genetic testing were assessed. Participants were randomly assigned to predict either their response to a positive HFE genotype (genotype group) or a positive iron test (phenotype group). RESULTS 71% preferred the iron test, but most would undergo either test. Learning risk and early detection/prevention were the most commonly perceived benefits; limited information about health and negative emotional consequences were the most commonly perceived disadvantages. The genotype and phenotype groups did not differ in expected worry, perceived severity, perceived risk, and preventability of organ damage. After reading the description provided, participants answered 78% of knowledge questions correctly. CONCLUSIONS Young adults view HFE genotyping positively and report few disadvantages, but prefer the iron test for its information about current health. They appear to be receptive to public health screening for hemochromatosis.

Abstract
This article presents an overview of the rapidly evolving body of literature on the psychological impact of genetic testing for hereditary breast/ovarian cancer susceptibility, hereditary non-polyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP). Uptake of genetic testing for BRCA1/2 and HNPCC-related mutations is more consistently related to psychological factors, rather than sociodemographic variables. Most studies on the psychological impact of genetic testing amongst individuals who have never been affected by cancer demonstrate that non-carriers derive significant psychological benefits from genetic testing, while no adverse effects have been observed amongst carriers. These benefits are more clear-cut for HNPCC, compared to hereditary breast/ovarian cancer, reflecting differences in risk management options. The few studies available on individuals affected with cancer indicate that the impact of genetic testing is mediated and amplified by their former experience of cancer. Future directions and challenges of research in this area are reviewed. In particular, more empirical data are needed on the broader impact of genetic testing on those with inconclusive results or results of uncertain significance. As genetic testing is becoming available for other types of familial cancer, additional investigations will be needed as there is evidence to suggest that the impact of genetic testing may be unique to each type of familial cancer.

Abstract
BACKGROUND A substantial minority of individuals who initially apply for genetic counselling for breast/ovarian cancer withdraw at an early stage from the counselling process. This study investigated the self-reported reasons for early withdrawal and the factors associated significantly with such withdrawal. METHODS Self-report questionnaires were mailed to 83 women who had applied for genetic counselling for breast/ovarian cancer but who subsequently withdrew from the counselling process (the "withdrawers"). A comparison group of 105 women who had completed the genetic counselling (the "attendees") received a similar questionnaire. The questionnaire assessed sociodemographic characteristics, reasons for applying for genetic counselling, general distress (MHI-5), cancer-specific distress (IES), and cancer worries. For those women who discontinued the counselling, reasons for withdrawal were also assessed. RESULTS The primary reasons given for withdrawing from counselling were difficulties in anticipating the consequences of genetic counselling (28%), and worries about being unable to adequately cope with an unfavourable test result (20%). Compared to the attendees, the withdrawers were significantly younger, more frequently asymptomatic, more often the first and only member of the family to apply for counselling, and less worried about cancer. Current levels of cancer-specific distress and general distress were comparable between the two groups. CONCLUSION Younger women, those without a history of cancer, and those who are first in their family to apply are more likely to withdraw prematurely from genetic counselling for breast/ovarian cancer. These withdrawers have no elevated levels of distress. However, a substantial percentage of individuals discontinue counselling due to concerns about their (in)ability to cope with a possible unfavourable test outcome. This suggests that greater attention should be paid to ways of coping with test results during the very first contact with the clinic.
