Abstract
This review aimed to develop a framework to understand the process of information management in families with inherited conditions. Electronic databases were searched for relevant peer-reviewed articles. Articles were included if they were original research on families affected by any confirmed inherited condition, described how a family accesses, interprets, conveys, and/or uses information about the disease, included the recruitment of more than one family member, and used family as the unit of analysis. Data were analyzed through directed content analysis. Thirty-four articles from 27 studies were analyzed. We propose a framework for family information management consisting of the following domains: contextual influences, family information management behaviors, and family information management outcomes. This proposed framework expands the understanding of how families manage their genetic information in making health care decisions for their affected and at-risk relatives.

Abstract
Germline genetic sequencing is now at the forefront of cancer treatment and preventative medicine. Cascade genetic testing, or the testing of at-risk relatives, is extremely promising as it offers genetic testing and potentially life-saving risk-reduction strategies to a population exponentially enriched for the risk of carrying a cancer-associated pathogenic variant. However, many relatives do not complete cascade testing due to barriers that span individual, relationship, healthcare community, and societal/policy domains. We have reviewed the published research on cascade testing. Our aim is to evaluate barriers to cascade genetic testing for hereditary cancer syndromes and explore strategies to mitigate these barriers, with the goal of promoting increased uptake of cascade genetic testing.

PEC INNOVATION 2023; 2:100133.

Abstract
Objective Evaluate an intervention to increase family communication (FC) of positive hereditary cancer test results using the Framework for Developing and Evaluating Complex Interventions (FDECI). Methods We developed 'programme theory' during the FDECI development phase by aligning intervention components with behavior change techniques (BCTs) and theoretical factors expected to improve FC. During the feasibility phase, we obtained feedback from 12 stakeholder interviews. Results Intervention components aligned with a total of 14 unique BCTs for which prior evidence links the BCT to theoretical factors that influence behavior change. Constructive stakeholder feedback included: more information desired, rewording to support autonomy by highlighting options, and improvements to navigation, visuals, and audio. Positive comments included: comprehensiveness of materials, modeling of conversations, and usefulness of the materials for helping a person prepare to share positive test results. Conclusion The first FDECI phases were helpful for improving the intervention and planning our ongoing effectiveness and future implementation phases. Innovation Our application of the FDECI is novel, including plans to test our 'programme theory' using coincidence analysis (CNA) to determine who accesses which intervention materials, how utilizing certain materials impact the aligned theoretical factors, and whether these in turn make a difference in the behavioral outcome.

Abstract
Younger-onset dementia (YOD) refers to onset before 65 years of age and may be associated with a genetic cause. Family communication surrounding any genetic risk is complex, and this process may be further complicated in a YOD context due to its effects on cognition, behaviour, and associated psychosocial consequences. This study aimed to investigate how individuals experience family communication about potential genetic risk and testing for YOD. Thematic analysis was performed on verbatim transcripts of nine semi-structured interviews undertaken with family members who attended a neurogenetics clinic due to a relative diagnosed with YOD. The interviews explored the participants’ experiences of learning that YOD might be inherited and the ensuing family communication about genetic testing. Four key themes emerged: (1) a clinical diagnostic odyssey was common and could be a motivator for genomic testing, (2) pre-existing family tension and/or disconnection was a common barrier, (3) family members’ autonomy was considered, and (4) avoidant coping strategies influenced communication. Communication regarding potential YOD genetic risk is a complicated process and may be influenced by pre-existing family dynamics, individual coping mechanisms, and a desire to promote autonomy in relatives. To promote effective risk communication, genetic counsellors should pre-emptively address family tensions that may be exacerbated in the context of genetic testing for YOD, with awareness that family strain during a preceding period of diagnostic odyssey is common. Genetic counsellors can offer psychosocial support to facilitate coping with this tension in an adaptive way. The findings also indicated the importance of extending genetic counselling support to relatives.

Abstract
Successful proband-mediated family communication and subsequent cascade genetic testing uptake requires interventions that present information clearly, in sufficient detail, and with medical authority. To facilitate family communication for patients receiving clinically actionable results via the MyCode® Community Health Initiative, a Family Sharing Tool (FST) and a cascade chatbot were developed. FST is an electronic mechanism allowing patients to share genetic test results with relatives via chatbot. The cascade chatbot describes the proband's result, associated disease risks, and recommended management and captures whether the user is a blood relative or caregiver, sex, and relationship to the proband. FST and cascade chatbot uptake among MyCode® probands and relatives was tracked from August 2018 through February 2020. Cascade genetic testing uptake was collected from testing laboratories as number of cascades per proband. Fifty-eight percent (316/543) of probands consented to FST; 42% (227/543) declined. Receipt preferences were patient electronic health record (EHR) portal (52%), email (29%), and text (19%). Patient EHR portal users (p < 0.001) and younger patients were more likely to consent (p < 0.001). FST was deployed to 308 probands. Fifty-nine percent (183/308) opened; of those, 56% (102/183) used FST to send a cascade chatbot to relatives. These 102 probands shared a cascade chatbot with 377 relatives. Sixty-two percent (235/377) of relatives opened; of these, 69% (161/235) started, and of these, 57% (92/161) completed the cascade chatbot. Cascade genetic testing uptake was significantly greater among relatives of probands who consented to the FST (M = 2.34 cascades, SD = 2.10) than relatives of probands who declined (M = 1.40 cascades, SD = 0.82, p < 0.001). Proband age was not a significant predictor of cascade genetic testing uptake. Further work is needed to better understand factors impacting proband use of FST and relative use of cascade chatbots.

Abstract
Hereditary cancer syndromes are inherited pathogenic genetic variants that significantly increase the risk of developing cancer. When individuals become aware of their increased probability of having cancer, the whole family is affected by this new reality and needs to adjust. However, adjustment to hereditary cancer syndromes has been mainly studied at an individual level, and research about familial adjustment remains dispersed and disorganized. To overcome this gap, this review aims to understand how families adjust to genetic testing and risk management, and to what extent the family's adjustment influences the psychological response and risk management behaviors of mutation carriers. We conducted searches on the PubMed/Med Line, PsycInfo, SCOPUS, and Google Scholar databases and used the Mixed Methods Appraisal Tool (MMAT-v2018) to assess the methodological quality of each selected study. Thirty studies met the inclusion criteria. Most results highlighted the interdependent nature of adjustment of pathogenic variant carriers and their families. The way carriers adjust to the syndrome is highly dependent on family functioning and related to how family members react to the new genetic information, particularly partners and siblings. Couples who share their worries and communicate openly about cancer risk present a better long-term adjustment than couples who use protective buffering (not talking about it to avoid disturbing the partner) or emotional distancing. Parents need help dealing with disclosing genetic information to their children. These findings reinforce the importance of adopting a family-centered approach in the context of genetic counseling and the necessity of involving family members in research.

Abstract
Successful translation of genetic information into patient-centered care and improved outcomes depends, at least in part, on patients' genetic knowledge. Although genetic knowledge is believed to be an important facilitator of familial communication of genetic risk information, empirical evidence of this association is lacking. We examined whether genetic knowledge was related to frequency of current familial communication about colorectal cancer and polyp (CRCP) risk, and future intention to share CRCP-related genomic test results with family members in a clinical sample of patients. We recruited 189 patients eligible for clinical CRCP sequencing to the eMERGE III FamilyTalk randomized controlled trial and surveyed them about genetic knowledge and familial communication at baseline. Participants were primarily Caucasian, 47% male, average age of 68 years, mostly well educated, and with high-income levels. Genetic knowledge was positively associated with future-intended familial communication of genetic information (odds ratio = 1.11, 95% confidence interval: 1.02-1.23), but not associated with current communication of CRC risk (β = 0.01, p = .58). Greater current communication of CRC risk was associated with better family functioning (β = 0.04, p = 8.2e-5). Participants' genetic knowledge in this study was minimally associated with their intended familial communication of genetic information. Although participants have good intentions of communication, family-level factors may hinder actual follow through of these intentions. Continued focus on improving proband's genetic knowledge coupled with interventions to overcome family-level barriers to communication may be needed to improve familial communication rates.

Abstract
Li-Fraumeni syndrome (LFS), a rare cancer predisposition syndrome caused by germline mutations in the TP53 gene, is associated with significant lifetime risk of developing cancer and warrants extensive and long-term surveillance. There are psychosocial impacts on individuals and families living with this condition, from the initial diagnosis throughout multiple stages across the lifespan, but these impacts have not been systematically reviewed and organized. The objective of this scoping review was to synthesize and characterize the literature on psychosocial screening and outcomes, educational needs, support services, and available interventions for patients and families with LFS. A systematic search of six databases was most recently conducted in August 2020: (PubMed/MEDLINE (NLM), EMBASE (Elsevier), Cochrane Library (Wiley), CINAHL (EBSCO), PsycINFO (OVID), and Web of Science (Clarivate Analytics). A total of 15 757 titles were screened, and 24 articles included. Several important themes were identified across studies: factors associated with TP53 genetic testing, LFS surveillance, psychological outcomes, and communication. Findings related to these themes were organized into age-specific categories (age agnostic/across the lifespan, childhood, adolescence and young adulthood, and adulthood).

Abstract
Family communication about the family's health history (FHH) is an important step in alerting individuals to their hereditary disease risks and facilitating prevention. Individuals often communicate about the FHH of hereditary cancer as a story, which highlights the importance of analyzing family narratives of hereditary cancer to better understand their relation to psychological and physical well-being. This study investigates the content of family stories by examining how narrative tone and framing relate to coping, perceptions of risk, and medical decision-making. The current study recruited 42 family dyads with a prevalent FHH of hereditary cancer to participate in dyadic phone interviews to jointly tell their family narrative of hereditary cancer. Using an iterative analysis, findings examine how families create a shared understanding of FHH and hereditary risk. Narrative tone reflects participants' psychological well-being and contributed to the way families framed their experiences. Common frames to family narratives of hereditary cancer included empowerment, adversity, laissez faire, and discrepant. Each frame gave insight into how families were coping, their perceptions of risk, and how they make medical decisions to manage those risks. Developing a better understanding of how families communicate about their hereditary cancer risks can aid in designing clinical interventions to help families re-frame their stories to promote improved health outcomes.

Abstract
A barrier to incorporating genomics more broadly is limited access to providers with genomics expertise. Chatbots are a technology-based simulated conversation used in scaling communications. Geisinger and Clear Genetics, Inc. have developed chatbots to facilitate communication with participants receiving clinically actionable genetic variants from the MyCode® Community Health Initiative (MyCode® ). The consent chatbot walks patients through the consent allowing them to opt to receive more or less detail on key topics (goals, benefits, risks, etc.). The follow-up chatbot reminds participants of suggested actions following result receipt and the cascade chatbot can be sent to at-risk relatives by participants to share their genetic test results and facilitate cascade testing. To explore the acceptability, usability, and understanding of the study consent, post-result follow-up and cascade testing chatbots, we conducted six focus groups with MyCode® participants. Sixty-two individuals participated in a focus group (n = 33 consent chatbot, n = 29 follow-up and cascade chatbot). Participants were mostly female (n = 42, 68%), Caucasian (n = 58, 94%), college-educated (n = 33,53%), retirees (n = 38, 61%), and of age 56 years or older (n = 52, 84%). Few participants reported that they knew what a chatbot was (n = 10, 16%), and a small number reported that they had used a chatbot (n = 5, 8%). Qualitative analysis of transcripts and notes from focus groups revealed four main themes: (a) overall impressions, (b) suggested improvements, (c) concerns and limitations, and (d) implementation. Participants supported using chatbots to consent for genomics research and to interact with healthcare providers for care coordination following receipt of genomic results. Most expressed willingness to use a chatbot to share genetic information with relatives. The consent chatbot presents an engaging alternative to deliver content challenging to comprehend in traditional paper or in-person consent. The cascade and follow-up chatbots may be acceptable, user-friendly, scalable approaches to manage ancillary genetic counseling tasks.

Family communication about genetic information enables informed medical and reproductive decision-making. The literature suggests that a significant proportion of genetically at-risk family members remain uninformed about genetic risk information as a result of non-disclosure. This study explored the experiences of New Zealand families communicating about a diagnosis of type 1 myotonic dystrophy (DM1). Eligible individuals were identified and recruited from the New Zealand (NZ) MD Prev study, a nationwide study which aimed to determine the prevalence, impact, and costs of genetic muscle disorders across the lifespan. Twelve qualitative semi-structured interviews were conducted with 17 participants. The findings demonstrate diversity among and within families, with several distinct family narratives described. Most participants reported a motivation to tell relatives about their diagnosis to promote autonomy. Women were pivotal throughout communication processes and this was often tied to the concept of maternal responsibility and a desire to promote relatives' reproductive autonomy. The diagnosis of DM1 and the subsequent family communication decisions altered relationships for many, with both positive and negative impacts described. The findings demonstrate that individuals require time to explore the impact of a diagnosis of DM1 on self, family and intimate partner relationships to anticipate unique communication challenges. Genetic counselors can use these findings to inform their approach to counseling families with DM1. Longitudinal genetic counseling may be beneficial as a way to provide individuals with life stage specific support as they communicate with their relatives about a diagnosis of DM1.

Abstract
Research on the communication of genetic test results has focused predominately on non-Hispanic White (NHW) mutation-positive families with high-risk hereditary cancer conditions. Little is known about this process for racially and ethnically diverse individuals or for those with mutations in moderate risk genes. The communication behaviors of study participants who carry a gene mutation were analyzed 3 months after disclosure of genetic test results. Participants were queried about communication of their results, as part of a prospective study of multi-gene panel genetic testing. The responses of particpants who tested positive were analyzed by race/ethnicity and by level of cancer risk (high vs. moderate). Of the 216 mutation-positive study participants, 136 (63%) responded. Self-reported race/ethnicity was 46% NHW, 41% Hispanic, 10% Asian, and 2% Black. The majority (99.0%, n = 135) had shared their results with someone and 96% had told a family member (n = 130). Hispanic respondents were less likely to have told a healthcare provider about their results than NHW (29% vs. 68%, p < .0001). Asian respondents were less likely than NHW to encourage family members to undergo testing (OR = 0.1, p = .03); but Asian family members were more likely to undergo testing (OR = 8.0, p = .03). There were no differences in communication between those with a mutation in a high- or moderate-risk gene. Three months post genetic testing, communication of results was very high; 30% reported a family member underwent genetic testing. Further studies are needed to better understand the communication process in individuals from diverse racial/ethnic backgrounds.

Abstract
BACKGROUND Advances in the application of genetic technologies reveal a growing number of heritable disorders associated with an increased risk to develop cancer during childhood. As genetic testing is increasingly employed in the clinical setting, it is essential to understand whether parents communicate with their children about test results and to elucidate the factors that influence the content and outcomes of these conversations. METHODS Semistructured interviews were conducted with 14 parents whose children tested positive for Li-Fraumeni syndrome (LFS). Semantic content analysis was performed on transcribed interviews, focusing on questions related to parent-child conversations about the genetic testing process and disclosure of positive test results. RESULTS All parents emphasized the importance of involving children in conversations about LFS. The majority (93%) identified as being part of "cancer families" in which prior experiences with cancer created opportunities for communication. While all had spoken with their children about cancer, only seven (50%) specifically disclosed to their children that they had tested positive for LFS. The most common reason cited for nondisclosure at the time of this study was the young age of the children. CONCLUSION Parents of children with LFS desire open conversations about genetic testing and cancer risk. These conversations are challenging yet essential to enable child understanding of genetic risk status and enhance compliance with health-promoting and cancer surveillance measures. Development of age-appropriate educational materials and novel clinical models to facilitate parent-child conversations about genetic test results and risk status for cancer are needed.

Abstract
Unaffected relatives of individuals with Lynch syndrome can be offered predictive genetic testing to guide surveillance recommendations. The decision-making process of those who decline testing, particularly those who do not attend a clinical genetics service, is poorly understood. We have addressed this gap by interviewing 33 individuals from Lynch syndrome mutation-carrying families, unaffected by cancer, who declined predictive genetic testing. Here, we analyse the data provided by 20 participants who unequivocally declined testing. Those who indicated they did not have enough information to make a decision or intended to undergo testing in the future were excluded. Analysis revealed that few decliners discussed their decision with general practitioners or genetic counsellors. Family members were commonly involved to varying degrees, with participants either (1) making group decisions with family members, (2) feeling persuaded by family members to either accept or decline testing, (3) discussing the test but making their own decision. A minority did not discuss testing with family members while making their decision. This research reveals the health communication activities of an understudied group, those declining predictive testing, and indicates that for many, health professionals play a minor role in the decision compared to family.

Abstract
OBJECTIVE In hereditary and familial cancer, counselees are requested to inform their at-risk relatives. We developed an intervention to support counselees in this task. METHODS A randomized controlled trial was conducted aimed at improving cancer genetic counselees' i) knowledge, ii) motivation to disclose information, and ii) self-efficacy in this regard. Eligible participants were randomized to telephonic counseling (n = 148), or standard care (n = 157) and assessed at baseline, 1 week post-intervention, and 4 months after study enrolment. RESULTS No between-group differences were found in participants' knowledge, motivation, and self-efficacy. Knowledge concerning which second-degree relatives to inform was lower compared to first-degree relatives. About 60% of the participants was of the opinion that they needed to inform more relatives than stated in their summary letter and only about 50% were correctly aware of which information to disclose. Of note, at baseline, almost 80% of the participants had already correctly informed their at-risk relatives. CONCLUSIONS Since, unexpectedly, counselees already informed most of their relatives before the intervention was offered, efficacy of the intervention could not convincingly be determined. Counselees' knowledge about whom to inform about what is suboptimal. PRACTICE IMPLICATIONS Future interventions should target a more homogeneous sample and address counselees' understanding and recall.

Abstract
Hereditary breast and ovarian cancer syndrome (HBOC) is a cancer predisposition syndrome that affects both men and women, with more significant cancer risk elevations in women. Dissemination patterns regarding familial genetic risk information among females with HBOC are fairly well defined, but knowledge about how males share this information is limited. We interviewed 21 people primarily Ashkenazi Jewish men who were accrued via listserv email through Facing Our Risk of Cancer Empowered (FORCE). Interviews focused on family cancer history, experiences with cancer and genetic testing, motivations to pursue genetic testing and subsequently disclose genetic test results, information-sharing patterns, health care provider response, and participants' emotional support systems. The interviews were transcribed in their entirety, coded, and analyzed based on recurring themes. Eighteen transcripts were used for the analysis. Results were classified into five main themes. Participants (n = 8) were most concerned about cancer risk for their children and female family members, and most (n = 11) mentioned that HBOC provides them increased personal awareness, but has a negligible impact on their life overall (n = 9). Men (n = 11) were interested in a male-focused support group to discuss HBOC and gain knowledge and information. Participants (n = 9) took on active and open communication roles with family members and health care providers. The majority of participants (n = 14) discussed the need for knowledge and awareness among the health care community and general population regarding male HBOC risks. This study serves as a pilot study and provides important and novel insights into psychosocial impacts, communication patterns, encounters with health care professionals, and expressed needs of males with HBOC.

Abstract
Genetic counseling and testing for familial cancer is a unique context for the communication of risk information in the family. This study utilized a theoretical framework based on the family systems perspective to understand intrafamilial cancer risk communication patterns in the Ashkenazi Jewish population. Individuals (n = 120) at an elevated risk for BRCA1/2 mutations were included. Change in communication patterns over time was assessed using McNemar tests. Associations with communication patterns were assessed with multivariable logistic regression. Overall, the proportion of participants encouraged by others significantly (p < .001) increased from before to after genetic counseling. A higher proportion of participants were encouraged by female family members compared with male family members. Participants who were older, had no personal history of cancer, and had a higher cancer risk perception were more likely to be encouraged by others for genetic testing. Participant's intent to encourage family members for genetic testing from before counseling to after receipt of genetic test results decreased by 16.7%. Participants who had no personal history of cancer and had informative test results for a BRCA1/2 mutation were more likely to encourage other family members for genetic testing. In addition, qualitative findings suggested that closeness among family members, concern for family, especially future generations, and cognizance about cancer risk facilitate information sharing and encouragement for genetic testing. Our findings indicate that intrafamilial cancer risk communication varies with the structure of family relationships and that genetic counseling can play an important role in improving intrafamilial cancer risk communication.

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
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
Cancer genetic counselees receive individualized information regarding heightened risks and medical recommendations which is also relevant for their at-risk relatives. Unfortunately, counselees often insufficiently inform these relatives. We designed an intervention aimed at improving counselees’ knowledge regarding which at-risk relatives to inform and what information to disclose, their motivation to disclose, and their self-efficacy. The intervention, offered by telephone by trained psychosocial workers, is based on the principles of Motivational Interviewing. Phase 1 of the intervention covers agenda setting, exploration, and evaluation, and phase 2 includes information provision, enhancing motivation and self-efficacy, and brainstorming for solutions to disseminate information within the family. Fidelity and acceptability of the intervention were assessed using recordings of intervention sessions and by counselee self-report. A total of 144 counselees participated. Psychosocial workers (n = 5) delivered the intervention largely as intended. Counselees highly appreciated the content of the intervention and the psychosocial workers who delivered the intervention. In the sessions, psychosocial workers provided additional and/or corrective information, and brainstorming for solutions was performed in 70 %. These results indicate that this intervention is feasible and warrants testing in clinical practice. For this, a randomized controlled trial is currently in progress to test the intervention’s efficacy.

Abstract
BACKGROUND Despite the use of genetic services, counselees do not always share hereditary cancer information with at-risk relatives. Reasons for not informing relatives may be categorized as a lack of: knowledge, motivation, and/or self-efficacy. PURPOSE This study aims to develop and test the psychometric properties of the Informing Relatives Inventory, a battery of instruments that intend to measure counselees' knowledge, motivation, and self-efficacy regarding the disclosure of hereditary cancer risk information to at-risk relatives. METHOD Guided by the proposed conceptual framework, existing instruments were selected and new instruments were developed. We tested the instruments' acceptability, dimensionality, reliability, and criterion-related validity in consecutive index patients visiting the Clinical Genetics department with questions regarding hereditary breast and/or ovarian cancer or colon cancer. RESULTS Data of 211 index patients were included (response rate = 62%). The Informing Relatives Inventory (IRI) assesses three barriers in disclosure representing seven domains. Instruments assessing index patients' (positive) motivation and self-efficacy were acceptable and reliable and suggested good criterion-related validity. Psychometric properties of instruments assessing index patients knowledge were disputable. These items were moderately accepted by index patients and the criterion-related validity was weaker. CONCLUSION This study presents a first conceptual framework and associated inventory (IRI) that improves insight into index patients' barriers regarding the disclosure of genetic cancer information to at-risk relatives. Instruments assessing (positive) motivation and self-efficacy proved to be reliable measurements. Measuring index patients knowledge appeared to be more challenging. Further research is necessary to ensure IRI's dimensionality and sensitivity to change.

Abstract
Ongoing challenges of clinical assessment of long QT syndrome (LQTS) highlight the importance of genetic testing in the diagnosis of asymptomatic at-risk family members. Effective access, uptake, and communication of genetic testing are critical for comprehensive cascade family screening and prevention of disease complications such as sudden cardiac death. The aim of this study was to describe factors influencing uptake of LQTS genetic testing, including those relating to access and family communication. We show those who access genetic testing are overrepresented by the socioeconomically advantaged, and that although overall family communication is good, there are some important barriers to be addressed. There were 75 participants (aged 18 years or more, with a clinical and/or genetic diagnosis of LQTS; response rate 71%) who completed a survey including a number of validated scales; demographics; and questions about access, uptake, and communication. Mean age of participants was 46 ± 16 years, 20 (27%) were males and 60 (80%) had genetic testing with a causative gene mutation in 42 (70%). Overall uptake of cascade testing within families was 60% after 4 years from proband genetic diagnosis. All participants reported at least one first-degree relative had been informed of their risk, whereas six (10%) reported at least one first-degree relative had not been informed. Those who were anxious or depressed were more likely to perceive barriers to communicating. Genetic testing is a key aspect of care in LQTS families and intervention strategies that aim to improve equity in access and facilitate effective family communication are needed.

Abstract
Facilitating family communication about Lynch syndrome is a public health priority since following appropriate screening guidelines can decrease morbidity and mortality. The aims of this study were to (1) ascertain what educational materials individuals with Lynch syndrome provide to at-risk relatives, and (2) identify relationships between receiving educational materials and pursuing clinical follow-up. Seventy-four participants, recruited from the Stanford Cancer Institute and a support group, completed an online questionnaire; 50 were first to be diagnosed with a Lynch syndrome mutation in their family (probands) and 24 were first or second-degree relatives. Probands reported informing 88 % (184/209) of first-degree relatives and 64 % (161/252) of second-degree relatives of the mutation. Probands shared their genetic counseling note with 53 % of relatives; other resources, including family letters, personal notes, testing laboratory information, online resources, support group information, and genetics referrals, were given to 33 % or fewer relatives. Probands reported that female relatives (p = 0.028) and first-degree relatives (p ≤ 0.001) were more likely to be given materials. Relatives who received an educational material were more likely to follow up with a clinician (74 vs 22 %, p ≤0.001) and attend a genetic counseling appointment (43 vs 16 %, p ≤ 0.001). First-degree relatives who received an educational material were more likely to have undergone genetic testing (51 vs 19 %, p = 0.012) and cancer screening (69 vs 29 %, p = 0.001). Facilitating information transmission in families with Lynch syndrome using educational materials may play a role in informed clinical decision-making and cascade screening of at-risk relatives.

Abstract
Inherited cardiac arrhythmias such as long QT syndrome and Brugada syndrome, present clinical as well as ethical, legal, and social challenges. Many individuals who carry a deleterious mutation are largely asymptomatic and therefore may not be diagnosed until after the occurrence of a personal or family member's cardiac event. The familial nature of inherited genetic information raises numerous ethical, legal, and social issues regarding the sharing of genetic information, particularly when an individual found to carry a deleterious mutation refuses to disclose his or her results to at-risk family members who could benefit from life-saving treatments. This qualitative study sought to understand the experiences with genetic testing for individuals (n = 50) with a personal or family history of cardiac events or sudden death. Unstructured in-person focus groups or interviews were conducted for each participant in the study. The recordings of these interviews were transcribed verbatim and subsequently analyzed and coded. Participants' comments regarding sharing of genetic information centered around four main themes: (1) motivation to disclose; (2) extent of disclosure; (3) effect of disclosure on family dynamics; and (4) reasons for not sharing genetic information. The majority of individuals believed that affected individuals are obligated to disclose genetic information to family members. In the era of personalized medicine, the disclosure of genetic information provides individuals the opportunities to learn about the genetics, disease characteristics, and treatment options in order to reduce morbidity and mortality in themselves and their family members. Further research is necessary to identify and explore the barriers to sharing genetic information with at-risk family members.

Abstract
Although screening reduces colorectal cancer (CRC) incidence and mortality, screening rates are low, particularly among CRC patients' first-degree relatives (FDRs). Little is known about discussion of family members' risk of CRC among patients and their health care providers or with their FDRs. The purpose of this research, guided by the Protection Motivation Theory, was to assess patients' patterns of disclosure of CRC diagnosis to adult siblings and/or children and discussion of familial risk by healthcare providers. A cross-sectional sample of patients who received care at a comprehensive cancer center was recruited to complete telephone-based interviews related to disclosure of CRC diagnosis to FDRs, recall of physician counseling about familial risk, and patients' perception of CRC risk to FDRs. Sixty-nine patients completed the interview. Most participants (n = 67, 97%) had informed their adult children or siblings of their CRC diagnosis to keep their family informed of their health status (n = 15, 22%) and to encourage FDRs to screen for CRC (n = 14, 20%). More than half of the participants' physicians (n = 38, 55%) discussed FDRs' risk of developing CRC with the patient. However, a substantial proportion of patients reported no physician discussion of this risk (n = 28, 41%). Data from this study may guide the development of interventions to facilitate physician discussion and counseling of CRC patients about their FDRs' risk for CRC. However, future studies should explore whether FDRs are likely to be screened after becoming aware of their family member's diagnosis of CRC.

Abstract
OBJECTIVE Genetic testing for hereditary cancer susceptibility syndromes is a family-centered process. Nonetheless, little research has explored how the family context affects psychological responses to genetic testing. We examine how personal test results and the test results of immediate and extended family members shape responses to genetic testing. METHODS Individuals at risk of carrying a mutation associated with an inherited cancer susceptibility syndrome (Lynch syndrome) received genetic testing. Six months after receiving their results, participants reported on cancer distress, cancer worry, and depressive symptoms. RESULTS Among mutation carriers for Lynch syndrome, the higher the proportion of carriers in their immediate family, the less cancer worry and distress they reported. In contrast, mutation carriers and non-carriers with a high proportion of carriers in their immediate family and mutation carriers with a high proportion of carriers in their extended family were at elevated risk for clinically significant levels of depressive symptoms. CONCLUSION Personal test results alone are not highly predictive of psychological outcomes. Instead, the interaction between personal and family test results, or in some cases, family test results alone, predict key psychological outcomes. The current research has important implications for genetic counseling and intervention efforts. Published 2014. This article is a U.S. Government work and is in the public domain in the USA.

Accuracy of recall of information about a cancer-predisposing BRCA1/2 gene mutation among patients and relatives. Eur J Hum Genet 2014; 23:147-51.

Abstract
This observational study aimed to (i) compare the accuracy of information recalled by patients and relatives following genetic counselling about a newly identified BRCA1/2 mutation, (ii) identify differences in accuracy of information about genetics and hereditary cancer and (iii) investigate whether accuracy among relatives improved when information was provided directly by genetics health professionals. Semistructured interviews following results from consultations with 10 breast/ovarian cancer patients and 22 relatives were audio-recorded and transcribed. Information provided by the genetics health professional was tracked through the families and coded for accuracy. Accuracy was analysed using the Wilcoxon Signed-Ranks test. Sources of information were tested using Spearman's rank-order correlation coefficient. Fifty-three percent of the information recalled by patients was accurate. Accuracy of recall among relatives was significantly lower than that among patients (P=0.017). Both groups recalled a lower proportion of information about hereditary cancer than about genetics (P=0.005). Relatives who learnt the information from the patient alone recalled significantly less accurate information than those informed directly by genetics health professionals (P=0.001). Following genetic counselling about a BRCA1/2 mutation, accuracy of recall was low among patients and relatives, particularly about hereditary cancer. Multiple sources of information, including direct contact with genetics health professionals, may improve the accuracy of information among relatives.

Abstract
BACKGROUND Genetic counseling for hereditary breast or colon cancer has implications for both counselees and their relatives. Although counselees are encouraged by genetic counselors to disclose genetic cancer risk information, they do not always share this information with their at-risk relatives. Reasons for not informing relatives may be generally categorized as a lack of knowledge, motivation and/or self-efficacy. Presented here is the protocol of a randomized controlled trial that aims to establish the effectiveness of an intervention focused on supporting counselees in their disclosure of genetic cancer information to their relatives. METHODS/DESIGN A multicenter randomized controlled trial with parallel group design will be used to compare the effects of an additional telephone counseling session performed by psychosocial workers to enhance the disclosure of genetic cancer information to at-risk relatives (intervention group) with a control group of standard care. Consecutive index patients with relatives at risk for hereditary or familial breast and/or ovarian cancer or colon cancer, are randomly assigned (block size: 8; 1:1 allocation ratio) to the intervention (n = 132) or control group (n = 132, standard care). Primary outcomes are counselees' knowledge, motivation and self-efficacy regarding informing their relatives. DISCUSSION This intervention may prove important in supporting counselees to disclose hereditary and/or familial cancer risk information to at-risk relatives and may enable more at-risk relatives to make a well-informed decision regarding genetic services and/or screening. TRIAL REGISTRATION This trial is registered in the Netherlands National Trial Register (NTR) with trial ID number NTR3745.

Abstract
In the care of patients with Lynch Syndrome (LS), a range of psychosocial issues are encountered, which significantly affect patient outcomes. A brief historical background of 'psycho-onco-genetics' (the domain where psychology, oncology and genetics meet) in relation to LS is presented, followed by an overview of important psychosocial issues identified in the past 20 years. The identification of mismatch repair genes in 1993-1994 made possible genetic counseling and testing for patients who had cancer and for potentially high-risk relatives without cancer. At that time, concerns were raised about the potentially negative psychosocial impact of predictive genetic testing. Since 1993, a large number of studies have been conducted to investigate the possible psychosocial benefits and limitations of such testing. This article presents an overview of: the uptake of and motivations for genetic testing, its psychosocial impact (e.g. psychological adaptation, impact on risk perception and self-concept, and concerns about, and experiences of, genetic discrimination), psychological screening instruments, adherence to and decision-making about preventive strategies, family communication, lifestyle changes, reproductive technology utilization, and professional psychosocial support needs of members of families with LS. Finally, challenges for the future are discussed, including population screening and genomic testing.

Abstract
Decisions for cancer susceptibility genetic testing (CSGT) uptake and dissemination of results occur within the family context. A national survey was performed with 990 patient-family member dyads (participation rate:76.2%), with paired questionnaires examining attitudes toward CSGT uptake and disclosure of results in response to a hypothetical scenario in which a reliable CSGT was available for the specific cancer a patient was being treated. While most patients and family members responded they would uptake or recommend CSGT if available, concordance between the dyads was poor for both patient's testing (agreement rate 77.5%, weighted κ=0.09) and first-degree relatives' testing(agreement rate 78.0%, weighted κ=0.09). Most patients (93.2%) and family members (92.9%) indicated that patients should disclose positive CSGT results to family members, with dyadic agreement of 89.1% (κ=0.15). However, there were substantial disagreement regarding when disclosure should take place, who should make the disclosure (the patient or the health care professionals), and to whom the results should be disclosed. Patients and family members may hold different attitudes toward CSGT uptake of and disclosure of results within the family. Our findings reinforce the need for a family system approach to incorporate perspectives of patients as well as their family members.

Abstract
When a cancer predisposing germline mutation is detected in an index case, the presence of the underlying syndrome is confirmed and the potential for predictive testing of at-risk relatives is established. However, the reporting of a positive family history does not routinely lead to communication of information about risk to close, much less distant relatives. This review summarizes information technology utilized to address penetration or 'reach' of knowledge of risk within extended families, including the use of telephone and video counseling to reach distant patients, and anticipate novel internet-based processes for communication between investigators and relatives.

Abstract
Newborn screening for cystic fibrosis and sickle cell disease enables the early identification and treatment of affected children, prolonging and enhancing their quality of life. Screening, however, also identifies carriers. There are minimal or no health concerns for carriers. There are, however, potential implications when carriers reach reproductive age, and thus research attention has been given to how best to convey information about these implications in a meaningful, balanced way which does not raise undue anxieties. Most research focuses on the communication from health professional to parent, yet ultimately this information is of greatest significance to the child. This study examines parents' intentions to inform their child of newborn screening carrier results. Semi-structured interviews with 67 family members explored their intentions to inform the child, and related views and support needs. Parents almost unanimously indicated they planned to inform the child themselves. Health professionals were expected, however, to provide guidance on this process either to parents through advice and provision of written materials, or directly to the child. Although parents initially stated that they would convey the result once their child had developed the ability to understand the information, many appeared to focus on discrete life events linked to informed reproductive decision making. The results highlight ways in which health care providers may assist parents, including providing written material suitable for intergenerational communication and ensuring that cascade screening is accessible for those seeking it. Priorities for further research are identified in light of the results.

Abstract
This article synthesises recent research examining how families live with genetic risk and the processes of genetic decision-making and disclosure among family members who have been or are at risk of transmitting a familial genetic condition. Its aim is to generate substantive theory that can inform our understanding of the interactional processes at work in the distribution of mutual knowledge and awareness of genetic risk in families. The article is structured around three interrelated concepts. Kinscape refers to the constellation of relations and relatedness that are recognised practically; timescape to the multiple temporal frames of social relations and their transformation and genescape to the constellation of knowledge, belief and practice surrounding genetic inheritance. All three concepts are simultaneously natural and cultural. Their intersections create the conditions of kinship and genetics.

PATIENT EDUCATION AND COUNSELING 2013; 92:53-60. [PMID: 23453851 DOI: 10.1016/j.pec.2013.02.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2012] [Revised: 01/16/2013] [Accepted: 02/03/2013] [Indexed: 06/01/2023]
Abstract
OBJECTIVE Data pertaining to Lynch syndrome within a developing country are sparse. This study explored the emotional reaction to a mutation-positive test result among a group of individuals from South Africa. As genetic information is not only limited to the individual but extends to the biological family, communication patterns and uptake of testing among at-risk family members was also investigated. METHODS Eighty individuals participated in this qualitative interview study. RESULTS Eight emotional reactions were observed, of which two were of particular concern: (1) secrecy due to disbelief and (2) interpretation of a mutation-positive result as a cancer diagnosis. Disclosure rates of personal genetic test results were high to family members, but low to general healthcare providers. Disclosing the test result was not always followed by a discussion of implications of the genetic information or availability of predictive testing for at-risk family members. The uptake rate of predictive testing among the participants' siblings and children was 97% and 73.6%, respectively. CONCLUSION Awareness of concerning emotional reactions following the delivery of a genetic test result and insight into disclosure patterns, especially the information that is not communicated, will prove beneficial in improving the effectiveness of counselling and management in Lynch syndrome families. PRACTICE IMPLICATIONS Implementation of these findings into the PT programme will have a positive effect on the genetic counseling process.

Abstract
It is estimated that 5 to 10% of all colorectal cancer (CRC) cases are attributed to a hereditary cause. The primary hereditary cancer syndromes that confer an increased risk for colorectal cancers are Lynch syndrome/hereditary nonpolyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP). Through genetic testing, health care providers can identify patients and families who carry gene mutations and subsequently are at a substantially greater risk for developing colorectal cancer than the general population. Genetic testing provides risk information not only about an individual patient, but also his or her biological relatives. A variety of risk-reduction behaviors (including screening, surgery, and health and lifestyle behaviors) have been examined in Lynch syndrome and FAP populations. The research indicates that screening behaviors are less than optimal, although the rates vary from study to study. Prophylactic colectomy is the primary course of treatment for individuals who test positive for a FAP mutation, but the results are inconclusive for cancer-unaffected Lynch syndrome mutation carriers. Although research suggests that the adoption of healthy lifestyles and behaviors (e.g., diet, physical activity, weight control, smoking cessation, limited alcohol consumption) could have a favorable impact on colon cancer burden, there is minimal data on how these behaviors may moderate cancer risk among those at risk of hereditary colon cancer. To date, we know very little about the actual health and lifestyle behaviors of those at risk of hereditary colon cancer. Genetic testing and counseling at risk individuals may resolve uncertainty about their personal and familial cancer risk and provide information to guide and personalize decisions about their future health care.

Abstract
Family communication of genetic risk information is a complex process. Currently, there are no evidence-based interventions to help genetics professionals facilitate the process of disclosure within families. This study was designed to create a framework to assist in the development of tools to support patients in communicating genetic risk information to family members. A systematic review identified the factors relevant in communicating genetic risk information in families. A guiding theory for the proposed framework was selected and populated with the factors identified from the review. The review identified 112 factors of relevance. The theory of planned behaviour was selected to guide framework development, organising the framework in terms of the patient's attitudes about disclosure, perceived pressure to disclose and perceived control over disclosure. Attitudes about disclosure are influenced by a desire to protect oneself or family members, and the patient's perceptions of relevance of the information for family members, responsibility to disclose, family members' rights to information and the usefulness of communicating. Perceived pressure to disclose information is shaped by genetic professionals, family members and society. Perceived control over disclosure is affected by family relationships/dynamics, personal communication skills, the ability of the patient and family to understand the information and coping skills of the patient and family member. The family genetic risk communication framework presents a concise synthesis of the evidence on family communication of genetic information; it may be useful in creating and evaluating tools to help genetic counsellors and patients with communication issues.

Abstract
This paper reports the results of semi-structured family interviews conducted with a purposive sample of nine families (comprising 50 individuals) involved in cancer genetic counselling at a Portuguese public hospital. Qualitative analysis resulted in thematic categories illustrating: (1) how families go through cancer genetic counselling (eliciting risk awareness, the motivators, risk management, the psychosocial context of familial engagement in genetic counselling, and the familial pathways of cancer risk tracking); and (2) how families incorporate genetic risk into family life (strategies for family resilience, and the meanings and values that permeate the experience). Families have recognised the value of genetic counselling in enabling participants to take measures to confront disease risk; however, the experience was dominated by distressing feelings. A set of ethical-relational principles guided the experience. Familial experiences on genetic counselling and tracking of cancer susceptibility encompass a sense of trajectory that takes the form of an historical and intergenerational narrative process, linking past, present and possible futures. Such process implies an ongoing set of individual and interactional experiences taking place over time. Specific changes associated with the illness timeline and with individual and family developmental lifespan transitions are thus acknowledged. These results may help genetics healthcare practitioners understand how families perceive, respond to and accommodate cancer risk counselling, and thus illuminate family-oriented tenets for planning and practice.

Abstract
Background A growing number of individuals are diagnosed with hereditary cancer. Though increased levels of anxiety and depression have been demonstrated around the time of genetic counselling, most individuals handle life at increased risk well. Data have, however, been collected on individual basis, which led us to focus on family perspectives of hereditary cancer. Methods Lynch syndrome represents a major type of hereditary colorectal and gynaecological cancer. We preformed open-ended interviews with 27 informants from 9 Lynch syndrome families. Inductive content analysis revealed three major themes: transition to a risk family, patterns of communication and influence on family relations and individual roles. Results Family members described how learning about Lynch syndrome shifted focus from daily issues to concerns about cancer. Changes in communication related to difficulties in talking to children about heredity and informing new family members and distant relatives about an increased risk of cancer. Influence on relations was exemplified by family members taking on different roles, e.g. females often being responsible for coordinating information about heredity and providing support. Families in which members had experienced cancer at young age typically informed children soon after learning about heredity and at young age, whereas families with experience of cancer at higher age postponed information and thereby also genetic counselling. Conclusions Three major family perspectives are described in Lynch syndrome families; becoming a risk family, patterns of communication and influence on family relations. Since these issues are central, our findings suggests that such family perspectives should be considered during genetic counselling in order to contribute to information spread, help family members cope with the increased risk, and motivate family members at risk to undergo surveillance.

Abstract
PURPOSE Appropriate management of autosomal dominant disorders reduces morbidity and mortality but relies on identifying which family members are affected. Genetic testing may identify relatives needing follow-up but is underused. We conducted this study to identify barriers to genetic testing for one disorder, hereditary hemorrhagic telangiectasia. METHODS Surveys and online discussion groups with people from hereditary hemorrhagic telangiectasia families. RESULTS Multiple barriers to hereditary hemorrhagic telangiectasia genetic testing were identified including lack of knowledge about genetic testing, problems with access, and emotional barriers. Many participants did not understand the rationale for hereditary hemorrhagic telangiectasia testing or benefits of early detection; believed that genetic testing is expensive and not covered by insurance; and believed that primary care providers do not know how to order genetic testing. Access to hereditary hemorrhagic telangiectasia testing is limited by distance from a hereditary hemorrhagic telangiectasia center or a genetics clinic. Emotional barriers include fear of insurance discrimination; denial of having hereditary hemorrhagic telangiectasia or being at risk; and guilt and stigma. CONCLUSION Voluntary disease organizations should develop and disseminate brief educational materials that describe the rationale for genetic testing and emphasize the benefits of early detection and treatment. In addition, laboratories offering genetic testing should provide support for primary care physicians to order and interpret genetic tests.

Abstract
Lynch syndrome (HNPCC) is an autosomal dominant hereditary cancer syndrome, and members of affected families are at-risk for developing colorectal and other associated tumors. Such individuals should disseminate familial genetic information, so they can seek specific medical assessment or genetic testing to reduce mortality and morbidity rates by early detection. Since published results have been encouraging, we explored which factors influence the likelihood of good communication within families regarding medical assessment. We studied 40 individuals from 33 families who satisfied the Japanese clinical criteria for Lynch syndrome and their relatives at our hospital. We determined the status of relatives of the 40 individuals after genetic counseling and testing using questionnaires and semi-structured interviews based on pedigree charts. We also examined their knowledge or perception of colorectal cancer syndrome, levels of intimacy and whether or not they encouraged their relatives to have specific medical assessments. We found that 75% of the individuals advised their relatives to seek medical assessment, and any significant background factors that promoted such encouragement were observed. They tended to encourage first degree relatives and discuss the issue with other family members such as spouses before undertaking such attempts at encouragement. The reasons and methods of imparting encouragement were essentially identical. We also found that genetic testing for at-risk or more distant relatives was not encouraged so often. Therefore, providing individuals who have been tested for Lynch syndrome with opportunities for disseminating familial genetic information through appropriate genetic counseling is important.

Abstract
The aim of this study was to establish key characteristics that patients, consumers, and health professionals value regarding genetic testing (GT) and personalized medicine using the example of GT for hereditary Lynch syndrome. We conducted a series of focus groups with individuals recruited from a clinic that follows those at high risk for hereditary cancer, individuals recruited from the community, physicians, and genetic counselors. Participants were presented with clinical scenarios about Lynch syndrome testing and asked to identify characteristics that they perceived as important in making decisions about GT. Forty-two participants (19 community members, 8 high-risk and cancer patients, 3 genetic counselors, and 8 physicians) participated. Among community members and patients, the most frequently discussed considerations were the personal impact of GT and family impact, respectively. Among physicians, the most frequently discussed topic was the characteristics of genomic services (e.g., test invasiveness); among genetic counselors, the most frequently discussed topic was evidence and recommendations. A variety of test characteristics were important in decision making about GT. High-risk patients, community members, and health care providers had different priorities. Health care professionals should be aware of differences between their own considerations about GT and those that are important to patients.

Abstract
In families meeting criteria for hereditary nonpolyposis colorectal cancer (HNPCC), genetic testing may or may not identify a mutation. Communication about genetic testing and risk in families with identified HNPCC mutations is associated with individual and relational factors. Similar communication patterns would be expected in families with similar clinical and pathological characteristics, but without an identified HNPCC mutation; however, previous studies have not included such families. Social network analysis was used to compare communication networks and associated individual and relational factors in families with and without identified HNPCC mutations. Respondents from families without identified mutations communicated about genetic counseling and testing and risk for HNPCC with a significantly smaller proportion of network members, compared to respondents from mutation-positive families. Members of families without identified mutations were also more likely to share thoughts about risk for HNPCC with network members whose advice they take, compared to members of families with known mutations. These findings extend our knowledge of communication in families at risk of HNPCC to include the many families in which a causative mutation has not yet been identified. Differences in the breadth of communication about genetics and risk for HNPCC, and the possibility that members of families without identified mutations may seek advice from those with whom they communicate about risk, provide new avenues for future research. Understanding existing communication patterns could help improve education and counseling processes, and facilitate the development of interventions designed to assist in family discussions of risk.

Abstract
Family communication is essential for accurate cancer risk assessment and counseling; family blockers play a role in this communication process. This qualitative analysis of social exchanges is an extension of earlier work characterizing those who are perceived by study participants as health information gatherers, disseminators, and blockers within families with Hereditary Breast and Ovarian Cancer (HBOC) susceptibility. Eighty-nine women, ages 23-56 years, enrolled in a Breast Imaging Study (BIS) and participated in a sub-study utilizing a social assessment tool known as the Colored Ecological Genetic Relational Map (CEGRM). Purposive sampling ensured that participants varied according to numbers of participating family members e.g., ranging from 1 to 6. Eighty-nine women from 42 families (1-8 relatives/family) participated. They collectively designated 65 blockers, both male and female. Situational factors, beliefs, attitudes and cultural traditions, privacy and protectiveness comprised perceived reasons for blocking intra-family health communications. Longitudinal data collected over 4 years showed families where blocking behavior was universally recognized and stable over time, as well as other families where blocking was less consistent. Self-blocking was observed among a significant minority of participating women. Blocking of health communications among family members with HBOC was variable, complex, and multifaceted. The reasons for blocking were heterogeneous; duration of the blocking appeared to depend on the reasons for blocking. Blocking often seemed to involve bi-directional feedback loops, in keeping with Lepore's Social Constraints and Modulation Theory. Privacy and protectiveness predominated as explanations for long-term blocking.

Abstract
BACKGROUND Testing has been advocated for all persons with newly diagnosed colorectal cancer to identify families with the Lynch syndrome, an autosomal dominant cancer-predisposition syndrome that is a paradigm for personalized medicine. OBJECTIVE To estimate the effectiveness and cost-effectiveness of strategies to identify the Lynch syndrome, with attention to sex, age at screening, and differential effects for probands and relatives. DESIGN Markov model that incorporated risk for colorectal, endometrial, and ovarian cancers. DATA SOURCES Published literature. TARGET POPULATION All persons with newly diagnosed colorectal cancer and their relatives. TIME HORIZON Lifetime. PERSPECTIVE Third-party payer. INTERVENTION Strategies based on clinical criteria, prediction algorithms, tumor testing, or up-front germline mutation testing, followed by tailored screening and risk-reducing surgery. OUTCOME MEASURES Life-years, cancer cases and deaths, costs, and incremental cost-effectiveness ratios. RESULTS OF BASE-CASE ANALYSIS The benefit of all strategies accrued primarily to relatives with a mutation associated with the Lynch syndrome, particularly women, whose life expectancy could increase by approximately 4 years with hysterectomy and salpingo-oophorectomy and adherence to colorectal cancer screening recommendations. At current rates of germline testing, screening, and prophylactic surgery, the strategies reduced deaths from colorectal cancer by 7% to 42% and deaths from endometrial and ovarian cancer by 1% to 6%. Among tumor-testing strategies, immunohistochemistry followed by BRAF mutation testing was preferred, with an incremental cost-effectiveness ratio of $36,200 per life-year gained. RESULTS OF SENSITIVITY ANALYSIS The number of relatives tested per proband was a critical determinant of both effectiveness and cost-effectiveness, with testing of 3 to 4 relatives required for most strategies to meet a threshold of $50,000 per life-year gained. Immunohistochemistry followed by BRAF mutation testing was preferred in 59% of iterations in probabilistic sensitivity analysis at a threshold of $100,000 per life-year gained. Screening for the Lynch syndrome with immunohistochemistry followed by BRAF mutation testing only up to age 70 years cost $44,000 per incremental life-year gained compared with screening only up to age 60 years, and screening without an upper age limit cost $88,700 per incremental life-year gained compared with screening only up to age 70 years. LIMITATION Other types of cancer, uncertain family pedigrees, and genetic variants of unknown significance were not considered. CONCLUSION Widespread colorectal tumor testing to identify families with the Lynch syndrome could yield substantial benefits at acceptable costs, particularly for women with a mutation associated with the Lynch syndrome who begin regular screening and have risk-reducing surgery. The cost-effectiveness of such testing depends on the participation rate among relatives at risk for the Lynch syndrome. PRIMARY FUNDING SOURCE National Institutes of Health.
