Family Communication, Risk Perception and Cancer Knowledge of Young Adults from BRCA1/2 Families: a Systematic Review

Can the Use of Artificial Intelligence-Generated Content Bridge the Cancer Knowledge Gap? A Longitudinal Study With Health Self-Efficacy as a Mediator and Educational Level as a Moderator

OBJECTIVES

The cancer knowledge gap represents a significant disparity in awareness and understanding of cancer-related information across different demographic groups. Leveraging Artificial Intelligence-Generated Content (AIGC) offers a promising approach to personalize health education and potentially bridge this gap. This study aimed to evaluate the potential of AIGC to bridge the cancer knowledge gap, assessing the roles of health self-efficacy as a mediator and educational level as a moderator in this relationship.

METHODS

A 6-month longitudinal study was conducted using online surveys distributed to undergraduate students in non-medical disciplines at one university and graduate students in medical specialties at another university in China. The study assessed the frequency of AIGC use, health self-efficacy, and cancer knowledge at two time points.

RESULTS

The results indicated that AIGC use significantly enhanced cancer knowledge levels and health self-efficacy over time. Educational level notably moderated the effects of AIGC use, with non-medical undergraduate students showing greater gains in knowledge and self-efficacy. Additionally, health self-efficacy mediated the relationship between AIGC use and cancer knowledge, underscoring the importance of health self-efficacy. The study confirms the efficacy of AIGC in narrowing the cancer knowledge gap and enhancing health self-efficacy, particularly among students with lower initial medical knowledge.

CONCLUSION

These findings highlight the potential of integrating AIGC tools in cancer education and public health interventions, particularly for individuals at different educational levels. By tailoring digital health resources to varying educational needs, these interventions could enhance cancer knowledge acquisition, improve health self-efficacy, and contribute to better cancer prevention and control outcomes.

Uncertainty Profiles and Treatment Preferences for Intraductal Papillary Mucinous Neoplasms

INTRODUCTION

Intraductal papillary mucinous neoplasms (IPMNs) are pancreatic premalignant lesions frequently detected incidentally. Choosing between surgery and surveillance for IPMNs is rooted in uncertainty. We characterized patient preferences in IPMN management, and examined associations with patients' uncertainty profiles (risk perception, risk attitude, and uncertainty tolerance).

METHODS

We conducted a cross-sectional survey drawn from a national opt-in panel. We simulated an encounter following an incidental computed tomography scan finding of an IPMN with a 5% cancer risk. We elicited participants' preferred treatment (surgery versus surveillance). Participant cancer risk perception, risk attitude (risk seeking versus risk averse), and uncertainty tolerance (comfort with the unknown) were determined using validated measures. Multivariate regression models assessed for independent predictors of treatment preference and risk perception.

RESULTS

The sample included 520 participants, ages 40-70, racially representative of the US population. Participants preferred surveillance (n = 331, 64%) over surgery (n = 189, 36%). Patients were significantly more likely to prefer surgery as their cancer risk perception increased (absolute difference = 12% from 1.0 standard deviation below to 1.0 standard deviation above the mean, 95% CI 3.5-20.2). Treatment preference was not significantly associated with risk attitude (P = 0.068) or uncertainty tolerance (P = 0.755). However, initial cancer risk perception was significantly associated with both uncertainty tolerance (P = 0.013) and baseline cancer anxiety (risk perception 16.4% versus 65%, not worried at all versus extremely worried, P < 0.001).

CONCLUSIONS

Patient preference varies widely for IPMN and is significantly associated with cancer risk perception, which is, in turn, significantly associated with uncertainty tolerance and cancer anxiety. These findings argue for the preference-sensitive nature of IPMN treatment decisions.

Information needs persist after genetic counseling and testing for BRCA1/2 and Lynch Syndrome

PURPOSE

Research has shown that cancer genetic risk is often not well understood by patients undergoing genetic testing and counseling. We describe the barriers to understanding genetic risk and the needs of high-risk persons and cancer survivors who have undergone genetic testing.

METHODS

Using data from an internet survey of adults living in the USA who responded 'yes' to having ever had a genetic test to determine cancer risk (N = 696), we conducted bivariate analyses and multivariable logistic regression models to evaluate associations between demographic, clinical, and communication-related variables by our key outcome of having vs. not having enough information about genetics and cancer to speak with family. Percentages for yes and no responses to queries about unmet informational needs were calculated. Patient satisfaction with counseling and percentage disclosure of genetic risk status to family were also calculated.

RESULTS

We found that a lack of resources provided by provider to inform family members and a lack of materials provided along with genetic test results were strongly associated with not having enough information about genetics and cancer (OR 4.54 95% CI 2.40-8.59 and OR 2.19 95% CI 1.16-4.14 respectively). Among participants undergoing genetic counseling, almost half reported needing more information on what genetic risk means for them and their family and how genetic testing results might impact future screening.

CONCLUSION

High levels of satisfaction with genetic counseling may not give a full picture of the patient-provider interaction and may miss potential unmet needs of the patient. Accessible resources and ongoing opportunities for updating family history information could reinforce knowledge about genetic risk.

Health-related roles of older generations in families with inherited genetic conditions: a scoping review

Inherited genetic conditions are family diseases. They affect consanguineous relatives, in lineage for several generations, and impact the family dynamics. Older generations have been considered highly influential in the health management of families with inherited genetic conditions. To our knowledge, no reviews so far addressed the health-related roles of older generations in these families. This scoping review aims to fill that gap by mapping the existent research about the health-roles roles performed by the older generations in families living with autosomal dominant inherited genetic conditions. Four electronic databases were searched: Scopus, Web of Science, PubMed, PsycInfo. Eleven studies were included, and relevant findings were extracted. Main roles included: informers vs. blockers of disease-related information; encouragers vs. discouragers of health screening or genetic testing; (non-)supporters; and role models in living and coping with the disease. The roles played by older generations are relevant to the health management of other family members and can be beneficial to themselves (reciprocal interactions). Acknowledging and understanding these roles is important for professionals and health-services. Results suggest the relevance of an intergenerational perspective when working with families with inherited genetic conditions.

Family Information Management in the Context of Inherited Conditions: An Integrative Review

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.

Impact of genomic literacy components on genetic testing decision-making in the general Japanese population in the 20s and 30s

In promoting genomic medicine, genomic literacy, which is the public's ability to acquire and utilize the knowledge and skills related to genetics and genomes, requires urgent improvement. This study determined how the three components of genomic literacy (genetic/genomic knowledge, health numeracy, and interactive and critical health literacy) are associated with risk and benefit perception for genetic testing and decision-making related to genetic testing. Using an online questionnaire, we surveyed genetic/genomic knowledge, health numeracy, interactive and critical health literacy, risk and benefit perception of genetic testing, and intention toward genetic testing of 857 Japanese citizens (aged 20-39). A vignette was created to measure the intention toward genetic testing, and respondents were asked about their willingness to undergo genetic testing and to share the results with their partners and children. The path analysis, which was done by creating a path diagram revealing the relationship of the three components with risk and benefit perception, revealed that genetic and genomic knowledge and interactive and critical health literacy affected the respondents' intention to undergo genetic testing via recognition of the benefits of such testing. Further, it was suggested that health numeracy affects benefit perception through risk perception toward genetic testing. However, the goodness of fit of this model for the intention of conveying positive results to partners and children was relatively low, thus indicating that the hypothetical model needs to be reexamined.

A systematic review of theory-informed strategies used in interventions fostering family genetic risk communication

BACKGROUND

Inherited risk is a family issue. Identifying family members who carry a pathogenic genetic variant that increases risk of cancers and other chronic diseases can be lifesaving for those affected.

OBJECTIVE

The research questions are: (1) which family communication frameworks have been applied, (2) how do intervention strategies employed map to these theories, and (3) to what extent were families receptive to these strategies and communication increased?

METHODS

Manuscripts published between January 2010 and August 2020 were searched in three databases: PubMed, PsycINFO, and Web of Science.

RESULTS

Nine intervention trials were identified. All interventions were evaluated in clinical genetic counseling contexts using at least one individual-level strategy (e.g. increase knowledge). Only three focused on dyadic conversations such as preparing for relatives' information needs.

CONCLUSIONS

This systematic review posed the question whether theoretically based approaches have been applied to foster family genetic risk communication. Greater attention needs to be paid to the utilization of dyadic level and family system level theories to guide intervention developments.

PRACTICAL IMPLICATIONS

We conclude by calling for accelerating and broadening the development of interventions to enable family communication about inherited risk that are theory-based, incorporate family-systems thinking, and are conducted outside of specialty clinic settings.

Psychological Determinants of Men’s Adherence to Cascade Screening for BRCA1/2

BRCA1/2 germline mutations predispose carriers to an increased risk of breast, ovarian, prostate, pancreatic, and skin cancer. Men and women are equally likely to pass on or inherit the pathogenic variant. However, there is evidence that male relatives are less involved in cascade screening than female ones. At the same time, little attention has been given to the research on psychological determinants of men’s adherence to cascade screening in BRCA1/2-positive families. Applying some principles of the Health Action Process Approach model, the present research tested a model of relationships on the adherence to BRCA1/2 cascade testing guidelines. The sample comprised 115 men’s first-degree relatives of women with verified germline mutations (Mage = 41.93; SD = 17.27). A pre–post test design was applied. Significant associations emerged between the intention to uptake BRCA1/2 genetic testing and age, parental status, breast cancer risk perception, self-referred outcome expectancies, perceived benefit, coping self-efficacy, and planning. Higher perceived benefit predicted increases in intention, and higher intention and coping self-efficacy predicted increases in planning. Intention was a positive total mediator of the relationship between benefit and planning. On a theoretical level, our findings partially supported the Health Action Process Approach as a valuable model based on which interventions could be developed in the context of cascade screening for BRCA1/2 genetic testing. Those results supported the importance of integrated genetic counselling sessions with a strict collaboration between geneticists and psychologists together with interventions planned to increase men’s self-monitoring ability to support their self-efficacy.

Cancer Predisposition Genes in Adolescents and Young Adults (AYAs): a Review Paper from the Italian AYA Working Group

PURPOSE OF REVIEW

The present narrative systematic review summarizes current knowledge on germline gene mutations predisposing to solid tumors in adolescents and young adults (AYAs).

RECENT FINDINGS

AYAs with cancer represent a particular group of patients with specific challenging characteristics and yet unmet needs. A significant percentage of AYA patients carry pathogenic or likely pathogenic variants (PV/LPVs) in cancer predisposition genes. Nevertheless, knowledge on spectrum, frequency, and clinical implications of germline variants in AYAs with solid tumors is limited. The identification of PV/LPV in AYA is especially critical given the need for appropriate communicative strategies, risk of second primary cancers, need for personalized long-term surveillance, potential reproductive implications, and cascade testing of at-risk family members. Moreover, these gene alterations may potentially provide novel biomarkers and therapeutic targets that are lacking in AYA patients. Among young adults with early-onset phenotypes of malignancies typically presenting at later ages, the increased prevalence of germline PV/LPVs supports a role for genetic counseling and testing irrespective of tumor type.

Application of motivational interviewing strategies with the extended parallel process model to improve risk communication for parents of children with familial hypercholesterolemia

Current genetic counseling practice has not been found to significantly increase risk communication between family members. A more diverse set of genetic counseling approaches may be needed. A genetic counseling intervention based on motivational interviewing principles and the extended parallel process model was utilized to increase cascade outcomes within families with familial hypercholesterolemia, a common, underdiagnosed, and treatable condition. Parents of children with familial hypercholesterolemia were invited to participate in an online pre-survey, single-session genetic counseling intervention, and post-intervention surveys as a part of the CHEERS (Cholesterol Evaluation to Explore Risk Screening) intervention. This study investigated the efficacy of a genetic counselor delivered motivational interviewing intervention and how parents of children with familial hypercholesterolemia react by assessing family member cholesterol screening and risk communication to at-risk relatives. Transcripts were audio-recorded, transcribed, and analyzed for change talk using the Motivational Interviewing Skill Code version 2.1. Participant surveys were analyzed for self-reported extended parallel process constructs and motivations. Coincidence analysis was conducted to explore differences between those with and without positive cascade outcomes within 12 months after the intervention. On average, change talk increased during the session in order of the extended parallel process constructs (perceived severity, susceptibility, response efficacy, self-efficacy). Coincidence analysis revealed that 6 of the 7 cases with positive cascade outcomes were explained by either the presence of high change talk during the intervention or presence of positive motivations shortly after, while 5 of the 5 cases without a positive outcome lacked both of these key factors that were associated with cascade outcomes. Results of this study suggest that incorporating motivational interviewing and the extended parallel process model increases change talk and that the presence of either high levels of change talk or positive motivations is associated with positive cascade outcomes.

Psychosocial interventions and needs among individuals and families with Li-Fraumeni syndrome: A scoping review

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).

Information needs on breast cancer genetic and non-genetic risk factors in relatives of women with a BRCA1/2 or PALB2 pathogenic variant

OBJECTIVES

Comprehensive breast cancer (BC) risk models integrating effects of genetic (GRF) and non-genetic risk factors (NGRF) may refine BC prevention recommendations. We explored the perceived information received on BC risk factors, and related characteristics, in female relatives of women with a BRCA1/2 or PALB2 pathogenic variant, undergoing BC risk assessment using the CanRisk© prediction tool.

METHODS

Of 200 consecutive cancer-free women approached after the initial genetic consultation, 161 (80.5%) filled in questionnaires on their perception of information received and wished further information on BC risk factors (e.g., being a carrier of a moderate risk altered gene, personal genetic profile, lifestyles). Multilevel multivariate linear models were performed accounting for the clinician who met the counselee and exploring the effect of counselees' socio-demographic, familial and psychological characteristics on the perceived extent of information received.

RESULTS

Perceived no/little information received and wish for further information were more frequent for NGRF (>50%) than for GRF, especially high-risk genes (<20%). Perceived amount of information received and desire for further information were inversely correlated (p=<0.0001). Higher education level related to lower perceived levels of information received on GRF. Younger counselees' age (β = 0.13, p = 0.02) and less frequent engagement coping (e.g., inclination to solicit information) (β = 0.24, p = 0.02) related to lower perceived information received about NGRF. Other assessed counselees' features were not found to be associated to GRF and NGRF information perception.

CONCLUSIONS

Awareness of counselees' perceived lack of information on BC risk factors indicates a need to enhance evidence-based information on BC NGRF especially.

Medical knowledge and information needs among women with pathogenic variants in moderate-risk genes for hereditary breast cancer attending genetic counseling at an academic hospital in Germany-A qualitative approach

With 69,000 newly diagnosed cases every year, breast cancer (BC) is the most frequent cancer disease among women in Germany. Familial clustering is seen in about 30% of newly diagnosed cases. Besides the high-risk genes BRCA1/2, there are also moderate-risk BC genes (MBCG) that are associated with a 20%-50% risk of BC, such as CHEK2, ATM, and PALB2. In Germany, carriers of pathogenic variants in MBCG receive specific information on their test results, individual risks, and preventive options during genetic counseling for the disclosure of the results in a specialized center. Little is known about the medical knowledge that women have after attending counseling. This study aims to identify the medical knowledge, further information needs, and the possible impact of a lack of information on dealing with everyday life for women with pathogenic variants in MBCG who have attended genetic counseling at an academic hospital in Germany. Problem-centered, guided, individual interviews were conducted with twelve women carrying pathogenic variants in MBCG. The interview guide was developed based on the methods of the problem-centered interview according to Witzel. The interview analysis was based on Mayring's qualitative content analysis. The women were between 29 and 59 years old and carried pathogenic variants in the risk genes CHEK2 (n = 8), ATM (n = 1), or PALB2 (n = 3). Several medical uncertainties and information needs emerged from the data, concerning (a) medical terms, (b) risk perception, (c) BC therapy for hereditary BC, (d) lifestyle advice and risk factors, and (e) family planning and risk-reducing mastectomy. Women with pathogenic variants in MBCG might develop their own conceptions regarding the onset of disease and inheritance. In order to meet the need for information and address the uncertainties that may still exist after genetic counseling, structured, evidence-based and comprehensible written information in German should be developed for this group.

Communication processes about predictive genetic testing within high-risk breast cancer families: a two-phase study design

The detection of a pathogenic variant in the BRCA1 or BRCA2 gene has medical and psychological consequences for both, affected mutation carriers and their relatives. A two-phase study with explanatory sequential mixed methods design examined the psychological impact of genetic testing and associated family communication processes. Analyzing a survey data of 79 carriers of a BRCA1 or BRCA2 mutation, the majority had general psychological distress independent of cancer diagnosis in the patients' history. The point prevalence of depression was 16.9%. Contrary to their subjective perception, the respondents' knowledge about those mutations was moderate. Despite the high rate of information transfer to relatives at risk (100%), their reported uptake of genetic testing was low (45.6%). Communication about the mutation detection was more frequent with female than with male relatives. In-depth focus group interviews revealed significant barriers to accessing genetic counseling including anxiety, uncertainty about the benefits of testing and about the own cancer risk, particularly among males. This study suggests that an adequate knowledge of the genetic background and psychological support is required to reduce emotional distress, to support familial communication and to facilitate genetic testing.

Multiple approaches to enhancing cancer communication in the next decade: translating research into practice and policy

Communicating risk and other health information in a clear, understandable, and actionable manner is critical for the prevention and control of cancer, as well as the care of affected individuals and their family members. However, the swift pace of development in communication technologies has dramatically changed the health communication landscape. This digital era presents new opportunities and challenges for cancer communication research and its impact on practice and policy. In this article, we examine the science of health communication focused on cancer and highlight important areas of research for the coming decade. Specifically, we discuss three domains in which cancer communication may occur: (a) among patients and their healthcare providers; (b) within and among families and social networks; and (c) across communities, populations, and the public more broadly. We underscore findings from the prior decade of cancer communication research, provide illustrative examples of future directions for cancer communication science, and conclude with considerations for diverse populations. Health informatics studies will be necessary to fully understand the growing and complex communication settings related to cancer: such works have the potential to change the face of information exchanges about cancer and elevate our collective discourse about this area as newer clinical and public health priorities emerge. Researchers from a wide array of specialties are interested in examining and improving cancer communication. These interdisciplinary perspectives can rapidly advance and help translate findings of cancer communication in the field of behavioral medicine.

"Let's Talk about Skin Cancer": Examining Association between Family Communication about Skin Cancer, Perceived Risk, and Sun Protection Behaviors

Family communication about skin cancer risk may motivate protective behaviors. However, it is unclear how widespread such communication might be. In this study, we describe prevalence and patterns (across environmental, personal, and behavioral factors) of family communication about skin cancer across N = 600 diverse (79% female, 48% Hispanic, 44% non-Hispanic White) primary care patients from Albuquerque, New Mexico, a geographical location with year-round sun exposure. Over half reported discussing general cancer (77%) and skin cancer risks (66%) with their families. The most frequent target of skin cancer risk communication included doctors (54%), followed by friends/coworkers (49%), spouse/partner (43%), other family members (38%), sisters (36%), mothers (36%), daughters (33%), sons (32%), father (24%), and brothers (22%). On average, participants reported having talked to three family members about skin cancer risks. The most frequently discussed content of skin cancer risk communication was the use of sun protection (89%), followed by the personal risk of skin cancer (68%), who had skin cancer in the family (60%), family risk of skin cancer (59%), time of sun exposure (57%), and skin cancer screening (57%). A family or personal history of cancer, higher perceived risk, higher health literacy, being non-Hispanic, having higher education or income, and proactive sun protective behavior were associated with greater family communication about general cancer and skin cancer risks. These study findings have implications for interventions that encourage discussions about skin cancer risk, sun protection, and skin cancer screening that lead to adoption of sun-safe behaviors.

Tumor surveillance for children and adolescents with cancer predisposition syndromes: The psychosocial impact reported by adolescents and caregivers

PURPOSE

Individuals with cancer predisposition syndromes (CPS) are often followed in cancer screening programs, which aim to detect early stage tumors. While cancer surveillance has the potential to improve patient outcomes, its psychosocial impact is uncharacterized in the pediatric population. We examined the cancer surveillance experience from the perspectives of adolescents and parents of children at risk of developing cancer.

PATIENTS AND METHODS

Using grounded theory and thematic analysis qualitative methodology, we conducted semi-structured interviews with parents and adolescents, separately. Interviews were transcribed verbatim and coded separately to derive overlapping and unique themes.

RESULTS

We completed 20 semi-structured interviews (11 parents and nine adolescents). Positive experiences were related to feelings of reassurance and taking a proactive approach. Both adolescents and parents experienced worry, related to practical aspects of screening, and related to the reminder of cancer risk that manifests with surveillance appointments. This worry was cyclical, associated with appointments, and generally waned over time. Participants felt that the benefits of surveillance outweighed perceived challenges. Open communication with health care providers, and equipping parents/adolescents with vocabulary to discuss their diagnosis and care with others, were felt to be important for mitigating worries associated with cancer risk and surveillance.

CONCLUSION

Parents and adolescents experience worry associated with surveillance for CPS, which may warrant regular psychosocial support, particularly during the first year following CPS diagnosis. Enhancing communication with the health care team and among and beyond immediate family members represents an additional important strategy to mitigate adverse experiences and perceptions.

Experiences of BRCA1/2 Gene Mutation-Positive Women With Cancer in Communicating Genetic Risk to Their Relatives

BACKGROUND

When a woman is diagnosed with hereditary breast or ovarian cancer, family members may be at high risk of cancers associated with BRCA1/2 gene mutation and benefit from disclosure of the genetic test result. This duty of informing relatives may be distressing, or relatives may not be properly informed.

OBJECTIVE

To qualitatively describe breast cancer patients' experiences communicating genetic risk of cancer to their relatives.

METHODS

Probands with BRCA1/2 gene mutations were recruited from an oncology institute in Istanbul, Turkey, and interviewed by telephone. Qualitative content analysis was conducted to derive central elements of the 30 women's experiences communicating genetic risk to their relatives.

RESULTS

Six themes were identified: response to genetic test results, reason for communication, feelings about communication, reflection after communication, results of communication, and needs.

CONCLUSION

Women with cancer found to have BRCA1/2 gene mutations tended to share their genetic test results within the family. The main motives for sharing test results were the desire to encourage relatives to get tested and moral and ethical convictions. Women needed explicit information regarding cancer risk and risk-reducing strategies to act upon.

IMPLICATIONS FOR PRACTICE

The women's feelings and reflections about the communication process were varied and suggest that personalized genetic risk communication interventions may better support women with BRCA1/2 gene mutations during and after communication with relatives. Long-term follow-up of those women is essential because of the need for informed decision on risk-reducing strategies.

Psychosocial factors related to BRCA1/2 disclosures

ABSTRACT

Patients who learn they carry breast cancer genes 1 and 2 (BRCA1/2) must decide if, when, and how they want to disclose this information to family members who may be affected. This article discusses the psychosocial factors that may influence patient decisions to disclose positive BRCA1/2 results to family members, as well as the role of nurses in educating and advocating for patients and their families.

Prevalence and Correlates of Family Cancer History Knowledge and Communication Among US Adults

Introduction

Knowing one’s family cancer history (FCH) plays an important role in cancer prevention. Communicating health histories with relatives can increase awareness about familial cancer risk and aid health care providers in personalizing cancer prevention recommendations.

Methods

This study used data from the National Cancer Institute’s 2018 Health Information National Trends Survey. We calculated frequencies and weighted population estimates for key FCH communication variables. Multivariable logistic regression models estimated associations between sociodemographic characteristics and FCH communication.

Results

Findings provide the first nationally representative estimates of FCH communication. Less than one-third (31.1%) of the population reported knowing FCH very well, 70.0% had discussed FCH with at least 1 biological relative, 39.0% had discussed FCH with a health care provider, and 22.2% reported being completely confident in completing FCH on medical forms. Findings also identified key demographic factors, including sex, household income, education level, and race and ethnicity, associated with these FCH measures among the US adult population.

Conclusion

Results can be used to target and tailor FCH communication interventions for patients, families, and providers.

Clinical characteristics and prognostic implications of BRCA-associated tumors in males: a pan-tumor survey

BACKGROUND

The BRCA mutation (BRCAm) in males has been reported to confer a higher risk for the development of various tumors. However, little is known about its clinicopathologic features and prognostic implications.

DESIGN

We conducted a retrospective pan-tumor survey on 346 cases of BRCA-associated tumors in males. Comparative analyses were conducted among male and female patients with BRCAm (n = 349), as well as in male patients without BRCAm (n = 4577).

RESULTS

Similar incidences of BRCAm (6.0 vs. 6.6%) and age at diagnosis of tumor (median, 65 vs. 60 years) were observed in male and female patients. Carcinomas of the lung, bladder, stomach, and cutaneous melanoma were the frequent tumors demonstrating BRCAm in males, of which the majority were stage II or III diseases with a higher frequency of BRCA2 mutations. Compared to that in the non-BRCAm group, cutaneous melanoma (16.3 vs. 5.0%), lung cancer (19.4 vs. 11.8%), bladder cancer (15.6 vs. 5.6%), and stomach cancer (11.9 vs. 5.5%) accounted for a higher proportion in the BRCAm group. Advanced disease and more mutation counts (median, 322 vs. 63 mutations) were also found in the BRCAm group. A total of 127 BRCA1 and 311 BRCA2 mutations were identified, of which 21.8 and 28.6% were deleterious, respectively. Frequent deleterious variants were identified in carcinomas of the breast (100.0%), colorectum (62.2%), prostate (43.3%), and stomach (42.9%). BRCA1 fusions with NF1, FAM134C, BECN1, or LSM12 and recurrent BRCA2 mutations at P606L/S, E832K/G, and T3033Lfs*29 were detected. Frameshift mutations in BRCA2 at N1784 (N1784Kfs*3, N1784Tfs*3) were frequently observed in both male and female patients. Compared with those in females, BRCA mutations in males were associated with decreased overall survival (OS) and progression-free survival (PFS). Male patients with deleterious BRCAm displayed increased OS compared with non-BRCAm carriers. The subgroup analysis demonstrated that BRCAm was associated with increased OS in gastric and bladder cancers, decreased PFS in prostate, esophageal, and head and neck cancers, and decreased OS in glioma/glioblastoma in males.

CONCLUSION

These findings provide an overview of the distinct characteristics and clinical outcomes of male patients with BRCA-associated tumors, suggesting the importance of further genetic BRCA testing in males.

From Probands to Relatives: Communication of Genetic Risk for Hereditary Breast-Ovarian Cancer and Its Influence on Subsequent Testing

BACKGROUND

The genetic risk communication from proband to relatives varies from family to family, and patients often need support with the communication of genetic test results and making decisions to manage hereditary cancer risks.

OBJECTIVE

The aim of this study was to characterize the communication of BRCA1 or BRCA2 (BRCA1/2) genetic risk from proband to first-degree relatives (FDRs) using a social network framework.

METHODS

We characterized network and nonnetwork factors to explore their association with which FDRs were told about the genetic risk and whether or not relatives underwent genetic testing. Ninety-two female probands with hereditary breast and ovarian cancer who have confirmed BRCA1/2 mutations participated in the study. Communication of hereditary breast and ovarian cancer risk was assessed between 92 probands and their 417 FDRs.

RESULTS

Of 92 probands, 94.5% (n = 87) communicated their genetic test result to at least one of their FDRs. Of FDRs older than 18 years, 19.9% (n = 72) have genetic testing. Emotional closeness, educational level of the proband, and relative's age were significantly associated with communicating test results with FDRs.

CONCLUSION

Communication of genetic risk with the FDRs after having a BRCA1/2 gene-mutation-positive test result was high in this group of cancer patients. However, the rate of genetic testing among FDRs was low.

IMPLICATIONS FOR PRACTICE

Probands' educational level and age of relatives for cascade genetic screening should be considered during counseling. Interventions to support women with BRCA1/2 mutations during the communication process and their family members' engagement in testing and risk-reducing strategies are needed.

Parent of Origin Effects on Family Communication of Risk in BRCA+ Women: A Qualitative Investigation of Human Factors in Cascade Screening

Pathogenic germline variants in Breast Cancer 1/2 (BRCA) genes confer increased cancer risk. Understanding BRCA status/risk can enable family cascade screening and improve cancer outcomes. However, more than half of the families do not communicate family cancer history/BRCA status, and cancer outcomes differ according to parent of origin (i.e., maternally vs. paternally inherited pathogenic variant). We aimed to explore communication patterns around family cancer history/BRCA risk according to parent of origin. We analyzed qualitative interviews (n = 97) using template analysis and employed the Theory of Planned Behavior (TPB) to identify interventions to improve communication. Interviews revealed sub-codes of ‘male stoicism and ‘paternal guilt’ that impede family communication (template code: gender scripting). Conversely, ‘fatherly protection’ and ‘female camaraderie’ promote communication of risk. The template code ‘dysfunctional family communication’ was contextualized by several sub-codes (‘harmful negligence’, ‘intra-family ignorance’ and ‘active withdrawal of support’) emerging from interview data. Sub-codes ‘medical misconceptions’ and ‘medical minimizing’ deepened our understanding of the template code ‘medical biases’. Importantly, sub-codes of ‘informed physicians’ and ‘trust in healthcare’ mitigated bias. Mapping findings to the TPB identified variables to tailor interventions aimed at enhancing family communication of risk and promoting cascade screening. In conclusion, these data provide empirical evidence of the human factors impeding communication of family BRCA risk. Tailored, theory-informed interventions merit consideration for overcoming blocked communication and improving cascade screening uptake.

Genetic testing for hereditary cancer syndromes: patient recommendations for improved risk communication

Background

Multi‐gene panel testing is replacing single‐gene testing for patients with suspected hereditary cancer syndromes. The detection of a hereditary cancer syndrome allows tested individuals to initiate enhanced primary and secondary prevention efforts—where available—with a view to reduce disease burden. Current policy prevents testing programmes from communicating genetic test results with potentially affected family members, yet it is well documented that tested individuals face multiple challenges in initiating such discussions with relatives.

Objective

In response to this challenge, we sought patient recommendations about how to improve genetic risk communication to enhance interfamilial discussions about primary and secondary disease prevention.

Design

We conducted 25 semi‐structured interviews with individuals who received genetic testing through British Columbia’s Hereditary Cancer Program between 2017 and 2018. Interviews were professionally transcribed and analysed using a constant comparative approach.

Results

Participants described difficulty engaging in conversations with relatives who were resistant to receiving genetic risk information, when communicating with younger relatives and where participants reported strained familial relationships. Participants recommended that testing facilities provide a summary of results and implications and that resources be made available to prepare patients for challenging discussions with family members.

Discussion

Our study demonstrates that individuals undergoing genetic testing for suspected hereditary cancer syndromes would benefit from additional supportive resources alongside genetic counselling. Providing this on‐going support will enhance the accurate and transparent communication of risk to facilitate the uptake of cascade testing and enhanced prevention strategies.

What Results Should Be Returned from Opportunistic Screening in Translational Research?

Increasingly, patients without clinical indications are undergoing genomic tests. The purpose of this study was to assess their appreciation and comprehension of their test results and their clinicians' reactions. We conducted 675 surveys with participants from the Vanderbilt Electronic Medical Records and Genomics (eMERGE) cohort. We interviewed 36 participants: 19 had received positive results, and 17 were self-identified racial minorities. Eleven clinicians who had patients who had participated in eMERGE were interviewed. A further 21 of these clinicians completed surveys. Participants spontaneously admitted to understanding little or none of the information returned to them from the eMERGE study. However, they simultaneously said that they generally found testing to be "helpful," even when it did not inform their health care. Primary care physicians expressed discomfort in being asked to interpret the results for their patients and described it as an undue burden. Providing genetic testing to otherwise healthy patients raises a number of ethical issues that warrant serious consideration. Although our participants were enthusiastic about enrolling and receiving their results, they express a limited understanding of what the results mean for their health care. This fact, coupled the clinicians' concern, urges greater caution when educating and enrolling participants in clinically non-indicated testing.

Genetic cancer risk assessment: A screenshot of the psychosocial profile of women at risk for hereditary breast and ovarian cancer syndrome

OBJECTIVE

There is a lack of information describing Brazilian women at risk of hereditary breast and ovarian cancer syndrome (HBOC) who undergo genetic cancer risk assessment (GCRA). This study aims to characterize the psychosocial profile of women at risk for HBOC at their first GCRA to obtain an overview of their families' profiles and the challenges of the oncogenetics setting.

METHODS

This was a cross-sectional study in which interviews were conducted with 83 cancer-affected women at their first GRCA appointment after the pedigree draw. Tools to evaluate psychological outcomes were applied. The pedigree genogram and ecomap were constructed and analyzed with content analysis using the "life course perspective" theory.

RESULTS

Individuals perceived their breast/ovarian cancer risk to be equal to that of the general population, although they were highly concerned about developing cancer. No evidence of anxiety or depressive symptoms was identified. Participants used the coping strategy of searching for religiosity. The genograms and ecomaps resulted in five major themes: support and social support; attitudes, feelings and emotions; cancer causes; communication; and relationships with relatives. Individuals between 20-29 years of age and those with no family history of cancer tended not to communicate with relatives, which may indicate future problems in the GCRA process regarding genetic testing.

CONCLUSIONS

This study demonstrated that knowing the families who undergo the GCRA process can help professionals provide more individualized and thorough attention during GCRA and genetic testing, which results in better follow-up and prevention strategies.

Development and testing of the KnowGene scale to assess general cancer genetic knowledge related to multigene panel testing

PURPOSE

To develop and evaluate a measure of cancer genetics knowledge relevant to multigene panel testing.

METHODS

The instrument was developed using systematic input from a national panel of genetics experts, acceptability evaluation by patient advocates, and cognitive testing. Twenty-four candidate items were completed by 591 breast or gynecological patients who had undergone genetic counseling and multigene panel testing in the past 18 months. A unidimensional item response theory model was fit with a mix of 2-parameter logistic nested response (2 plnrm) and 2-parameter logistic (2 pl) items.

RESULTS

Key domains addressing cancer genetics knowledge were found to be overlapping. Of the 24 candidate items, 8 items were removed due to poor discrimination or local dependence. The remaining 16 items had good fit (RMSEA = 0.045, CFI = 0.946) and discrimination parameters ranging from 0.49 to 1.60. The items specified as 2 plnrm distinguish between those answering incorrect versus don't know, with discrimination ranging from 0.51 to 1.02. Information curves were highest among those with lower knowledge.

CONCLUSION

KnowGene is a rigorously developed and effective measure of knowledge after cancer genetic counseling and multigene panel testing.

PRACTICE IMPLICATIONS

Measuring knowledge in a systematic way will inform practice and research initiatives in cancer genetics.

Uptake of genetic counseling among adult children of BRCA1/2 mutation carriers in France

OBJECTIVE

Genetic counseling in at-risk families is known to improve cancer prevention. Our study aimed to determine the rate of uptake of genetic counseling among adult children of BRCA1/2 mutation carriers and to identify the potential psychosocial factors associated with uptake of genetic counseling.

METHODS

A self-reported questionnaire was mailed to 328 BRCA1/2 mutation carriers 10 years after BRCA1/2 test disclosure. Of the 233 carriers who returned the questionnaire (response rate = 71%), 135 reported having children over age 18 years and were therefore included in the analysis. Generalized estimating equations models were used to identify the factors associated with uptake of genetic counseling among adult children of mutation carriers.

RESULTS

Data were gathered for a total of 296 children (46% male, 54% female). The vast majority were informed about the familial mutation (90.9%) and 113 (38%; 95% CI, 32%-44%) underwent genetic counseling. This percentage exceeded 80% in women over 40 years. In the multivariate model, female sex, advanced age, mutation in the father, diagnosis of cancer in the mutation-carrying parent after genetic testing, and good family relationships were all factors associated with higher uptake of genetic counseling.

CONCLUSIONS

Adult children of BRCA1/2 mutation carriers in France do not undergo genetic counseling sufficiently often. Further studies should be conducted on the psychosocial factors that hinder the uptake of genetic counseling among adult children of BRCA1/2 mutation carriers.

Evaluating a custom-designed aid to improve communication of genetic results in families with hypertrophic cardiomyopathy: study protocol for a randomised controlled trial

INTRODUCTION

Genetic testing for hypertrophic cardiomyopathy (HCM) in the era of genomics brings unique challenges for genetic counselling. The number of genes routinely included in an HCM gene panel has increased markedly, many with minimal if any robust evidence of gene-disease association. Subsequently, there is a greater chance of uncertain genetic findings. The responsibility of communicating this information with at-risk relatives lies with the index case (proband). We have developed a communication aid to assist with the delivery of genetic results to the proband. We have previously shown the aid is feasible and acceptable and have now developed a study protocol for a randomised controlled trial of a genetic counsellor-led intervention incorporating the communication aid.

METHODS AND ANALYSIS

This is a prospective randomised controlled trial. We will investigate the impact of a genetic counsellor-led intervention to return proband genetic results using a custom-designed communication aid. We aim to improve knowledge and empowerment. The primary outcome of this trial is the ability and confidence of the proband to communicate genetic results to at-risk relatives. Secondary outcomes will assess genetic knowledge, satisfaction with services, outcomes from genetic counselling and psychological adaptation to genetic information.

ETHICS AND DISSEMINATION

This study has been approved by and is in strict accordance with the Sydney Local Health District Ethics Review Committee (X16-0030; 22/01/2016; version 1). Results from this trial will be prepared as a manuscript and submitted to peer-reviewed journals for publication as well as submission for presentation at national and international meetings.

Legacies and Relationships: Diverse Social Networks and BRCA1/2 Risk Management Decisions and Actions

In families with hereditary breast/ovarian cancer, complex disease histories challenge established patterns of family communication and influence decision-making for clinical surveillance, genetic testing, and risk management. An interdisciplinary team examined longitudinal interview data from women with identified BRCA1/2 mutations to assess interactions within family and social networks about risk information communication and management. We used interpretive description to identify motivation, content, and derived benefit of these interactions. Participants discussed risk information and management strategies with biological and nonbiological network members for multiple purposes: discharging responsibility for risk information dissemination, protecting important relationships, and navigating decision trajectories. Evolving interactions with loved ones balanced long-standing family communication patterns with differing personal preferences for privacy or open sharing, whereas interactions with nonbiological network members expanded participants' range of choices for sources of risk management information. Ongoing assessment of social networks may help support engagement with risk management by aligning with patient social needs.

Patients' perspectives and experiences concerning barriers to accessing information about bilateral prophylactic mastectomy

PURPOSE

To explore the barriers and experiences of accessing information for women who have received genetic risk assessment/testing results for breast cancer (BC) and are considering a bilateral prophylactic mastectomy (BPM) and, exploring participants' preferences concerning information and support needs.

METHODS

A qualitative retrospective study guided by interpretative phenomenological analysis was utilised. Semi-structured interviews were conducted with forty-six women who were either considering BPM or had already undergone the surgery.

RESULTS

Three themes identified barriers to accessing information; difficulties accessing information, inconsistent information and clinical focus/medicalized information. A fourth theme - preferences of information and support needs, identified three subthemes; these were, psychological support, clearly defined processes and photos of mastectomies/reconstruction surgeries.

CONCLUSIONS

Barriers to accessing information appeared to be widespread. A lack of integrated services contributed to inconsistent information, and medicalized terminology/clinical focus of consultations further complicated understanding. Preferences for information include clearly defined processes, so women know the pathways after confirmation of familial BC risk. Clinical implications include a multidisciplinary team approach, and a protocol that reflects current practice.
