Kwong A, Tan DSP, Ryu JM. Current practices and challenges in genetic testing and counseling for women with breast and ovarian cancer in Asia. Asia Pac J Clin Oncol 2024. [PMID: 38776249 DOI: 10.1111/ajco.14074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 04/04/2024] [Accepted: 04/15/2024] [Indexed: 05/24/2024]
Abstract
AIM This study assesses current practices and challenges in genetic testing and counseling (GT and C) for breast cancer gene (BRCA)1/2 mutations in Asia, considering the increased risk of ovarian cancer (OC) and breast cancer (BC) in women carrying these mutations. METHODS Insights were gathered through a questionnaire from breast surgeons, gynecologists, oncologists, and genetic clinicians in 10 Asian countries: Thailand, Hong Kong, South Korea, India, Vietnam, Malaysia, the Philippines, Taiwan, Singapore, and Indonesia. The questionnaire covered their knowledge, attitudes, and practices in GT and C for BRCA1/2 mutations, along with information on perceived gaps and unmet needs in the region. RESULTS A total of 61 specialists participated in the survey. GT and C for BRCA1/2 mutations were less frequently offered in Asia compared to Western countries. Among the guidelines used, the National Comprehensive Cancer Network (NCCN) guidelines alone or in combination with other guidelines (American Society of Clinical Oncology [ASCO], National Institute for Health and Clinical Excellence [NICE], and European Society for Medical Oncology [ESMO]) were preferred for both BC and OC. Limited access to genetic counselors posed a significant challenge, resulting in delayed or no GT. Pretest genetic counseling was provided by the respondents themselves. Germline testing was preferred for BC, whereas both germline and somatic testing were preferred for OC, with the most preferred option being a multipanel germline test. CONCLUSION Disparities exist in GT and C practices between Asian and Western countries. To address this, steps, such as patient and doctor education, increased accessibility and affordability of GT and C services, and improved infrastructure for identifying gene mutations, should be taken.

Talking numbers: how women and providers use risk scores during and after risk counseling - a qualitative investigation from the NRG Oncology/NSABP DMP-1 study. BMJ Open 2023; 13:e073138. [PMID: 37984961 PMCID: PMC10660821 DOI: 10.1136/bmjopen-2023-073138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Accepted: 09/29/2023] [Indexed: 11/22/2023] Open
Abstract
OBJECTIVES Little research exists on how risk scores are used in counselling. We examined (a) how Breast Cancer Risk Assessment Tool (BCRAT) scores are presented during counselling; (b) how women react and (c) discuss them afterwards. DESIGN Consultations were video-recorded and participants were interviewed after the consultation as part of the NRG Oncology/National Surgical Adjuvant Breast and Bowel Project Decision-Making Project 1 (NSABP DMP-1). SETTING Two NSABP DMP-1 breast cancer care centres in the USA: one large comprehensive cancer centre serving a high-risk population and an academic safety-net medical centre in an urban setting. PARTICIPANTS Thirty women evaluated for breast cancer risk and their counselling providers were included. METHODS Participants who were identified as at increased risk of breast cancer were recruited to participate in qualitative study with a video-recorded consultation and subsequent semi-structured interview that included giving feedback and input after viewing their own consultation. Consultation videos were summarised jointly and inductively as a team.tThe interview material was searched deductively for text segments that contained the inductively derived themes related to risk assessment. Subgroup analysis according to demographic variables such as age and Gail score were conducted, investigating reactions to risk scores and contrasting and comparing them with the pertinent video analysis data. From this, four descriptive categories of reactions to risk scores emerged. The descriptive categories were clearly defined after 19 interviews; all 30 interviews fit principally into one of the four descriptive categories. RESULTS Risk scores were individualised and given meaning by providers through: (a) presenting thresholds, (b) making comparisons and (c) emphasising or minimising the calculated risk. The risk score information elicited little reaction from participants during consultations, though some added to, agreed with or qualified the provider's information. During interviews, participants reacted to the numbers in four primary ways: (a) engaging easily with numbers; (b) expressing greater anxiety after discussing the risk score; (c) accepting the risk score and (d) not talking about the risk score. CONCLUSIONS Our study highlights the necessity that patients' experiences must be understood and put into relation to risk assessment information to become a meaningful treatment decision-making tool, for instance by categorising patients' information engagement into types. TRIAL REGISTRATION NUMBER NCT01399359.

Abstract
OBJECTIVE Conduct a needs assessment to explore the experiences, barriers, and needs of genetic counselors (GCs), who counsel and refer young and metastatic breast cancer (BC) patients to support services, in order to develop resources to address any noticeable gaps. METHODS GCs providing care to BC patients were eligible to complete the survey. Support services were defined as resources to address patient-centered healthcare, emotional, and quality-of-life needs. RESULTS Most participants (n = 117) reported familiarity with cancer prevention services (93%); fewer were familiar with services secondary to a BC diagnosis (e.g., fatigue=16% and sexual health=24%). The volume of GCs indicating familiarity with support services increased significantly as work experience increased for seven services. Many (>50%) never referred patients to most (9/12) support services, excluding cancer prevention, mental health, and financial issues. Open-ended responses highlighted that GCs considered referrals to be outside their scope of practice or that healthcare systems prevent GCs from making referrals. CONCLUSION GCs may benefit from curated resources and materials, especially for support services secondary to a BC diagnosis, to better support their patients. PRACTICAL IMPLICATIONS Collaboration of GCs with other health professionals through integrative care programs may decrease burdens to accessing support services.

PLoS One 2023; 18:e0278742. [PMID: 36857397 PMCID: PMC9977014 DOI: 10.1371/journal.pone.0278742] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Accepted: 11/19/2022] [Indexed: 03/02/2023] Open
Abstract
PURPOSE Women at high risk of breast cancer face complex decisions about how to manage those risks. Substantial gaps in current knowledge include how women make these decisions and how decision making may differ across sub-populations. Among these critical gaps are the questions of (a) whether racial differences exist between the experiences of high-risk women navigating breast cancer risk, and (b) what consequences those racial differences might have on women's ability to manage their cancer risks. The present study is designed to address these questions directly. METHODS Fifty semi-structured interviews were conducted with high-risk Black (n = 20) and white women (n = 30) between May 2015 and March 2016 in person in Ohio and by phone. Transcribed data were analyzed using grounded theory methods. MAIN FINDINGS Our analyses suggest that many of the core decision-making dynamics high-risk women navigate differ by race. The experiences of white and Black women in our study differ in terms of (a) contextualizing risk-how women make sense of their own breast cancer risk, the degree to which they worry about risk, and how they prioritize risk within the contexts of their broader lives; (b) conceptualizing risk management-how, how much, and from whom women learn about and conceptualize their options for preventing cancer and/or ensuring that cancer gets diagnosed early; and (c) constraints-the external barriers women face throughout their decision-making and risk-management processes. In sum, the Black women we interviewed reported feeling less well-situated to consider and cope actively with breast cancer risk, less well-informed about risk-management options, and more constrained in their use of these options. CONCLUSIONS High-risk women's accounts of the complex dynamics that shape breast cancer prevention decisions suggest that these dynamics vary substantially by race, such that Black women may experience disadvantages relative to whites.

Abstract
OBJECTIVE As germline genetic referral becomes increasingly routine as part of the care of newly diagnosed breast cancer patients, it is important to understand the psychosocial impact of genetic counseling at the time of diagnosis. We examined the psychosocial and quality of life (QOL) impact of providing proactive rapid genetic counseling and testing (RGCT) in the immediate aftermath of a breast cancer diagnosis. METHODS We randomized 330 patients in a 2:1 ratio to proactive rapid genetic counseling (RGCT; N = 222) versus usual care (UC; N = 108). Participants completed a baseline telephone survey before randomization and definitive surgery and a follow-up survey at 1-month post-randomization. We evaluated the impact of RGCT versus UC on breast cancer genetic knowledge, distress, QOL, and decisional conflict. Given that 43% of UC participants and 86% of RGCT participants completed genetic counseling prior to the 1-month assessment, we also evaluated the impact of genetic counseling participation over and above group assignment. RESULTS The RGCT intervention led to increased breast cancer genetic knowledge relative to UC but did not differentially impact other study outcomes. Across groups patients who participated in genetic counseling had significantly increased knowledge and improved QOL compared to those who did not participate in genetic counseling. CONCLUSIONS While prior research has documented the impact of genetic counseling and testing on surgical decisions, these results confirm that participation in genetic counseling at the time of diagnosis can yield improvements in knowledge and QOL in the short-term.

Abstract
OBJECTIVES Genetic testing (GT) companies have developed patient education videos to supplement or replace pre-test genetic counseling (GC) by certified genetic counselors (CGC). The aim of this study was to assess the quality of these videos compared to the standard of care (SOC). METHODS Videos from four major GT companies were selected from an internet search identifying pre-test patient education videos. A scoring rubric with 22 questions and 36 total points was devised to assess quality metrics, as described by the National Cancer Institute and National Society of Genetic Counselors. Twenty-two individuals with varying genetics expertise (3 gynecologic oncologists, 3 academic generalists, 4 CGC, a genetics community health worker, 3 cancer care navigators, and 8 medical students) scored each video. Scorers were blinded to others' assessments. RESULTS Invitae had the highest median score (26/36), followed by Myriad (22/36), Ambry (17.5/36), and Color (15/36). All videos scored highly in explaining DNA basics, cancer development, and hereditary cancer predisposition. All addressed benefits of GT but failed to address potential disadvantages. All scored poorly in explaining medical terms and different GT options. There was variability in addressing patient concerns including cost, privacy, and procedure. CONCLUSIONS There is significant variation in the content of pre-test patient education videos between GT companies. None of the videos met the SOC for pre-test GC, and none addressed disadvantages of GT, possibly due to a conflict of interest. With improvement in content, accessibility, and use of interactive platforms, these videos may serve as an adjunct to in-person pre-test GC.

Abstract
Cancer risk assessment and genetic counseling for hereditary breast and ovarian cancer (HBOC) are a communication process to inform and prepare patients for genetic test results and the related medical management. An increasing number of healthcare providers are active in the delivery of cancer risk assessment and testing, which can have enormous benefits for enhanced patient care. However, genetics professionals remain key in the multidisciplinary care of at-risk patients and their families, given their training in facilitating patients' understanding of the role of genetics in cancer development, the potential psychological, social, and medical implications associated with cancer risk assessment and genetic testing. A collaborative partnership of non-genetics and genetics experts is the ideal approach to address the growing number of patients at risk for hereditary breast and ovarian cancer. The goal of this practice resource is to provide allied health professionals an understanding of the key components of risk assessment for HBOC as well as the use of risk models and published guidelines for medical management. We also highlight what patient types are appropriate for genetic testing, what are the most appropriate test(s) to consider, and when to refer individuals to a genetics professional. This practice resource is intended to serve as a resource for allied health professionals in determining their approach to delivering comprehensive care for families and individuals facing HBOC. The cancer risk and prevalence figures in this document are based on cisgender women and men; the risks for transgender or non-binary individuals have not been studied and therefore remain poorly understood.

Abstract
Background Risk assessment is a precision medicine technique that can be used to enhance population health when applied to prevention. Several barriers limit the uptake of risk assessment in health care systems; and little is known about the potential impact that adoption of systematic risk assessment for screening and prevention in the primary care population might have. Here we present results of a first of its kind multi-institutional study of a precision medicine tool for systematic risk assessment. Methods We undertook an implementation-effectiveness trial of systematic risk assessment of primary care patients in 19 primary care clinics at four geographically and culturally diverse healthcare systems. All adult English or Spanish speaking patients were invited to enter personal and family health history data into MeTree, a patient-facing family health history driven risk assessment program, for 27 medical conditions. Risk assessment recommendations followed evidence-based guidelines for identifying and managing those at increased disease risk. Results One thousand eight hundred eighty-nine participants completed MeTree, entering information on N = 25,967 individuals. Mean relatives entered = 13.7 (SD 7.9), range 7–74. N = 1443 (76.4%) participants received increased risk recommendations: 597 (31.6%) for monogenic hereditary conditions, 508 (26.9%) for familial-level risk, and 1056 (56.1%) for risk of a common chronic disease. There were 6617 recommendations given across the 1443 participants. In multivariate analysis, only the total number of relatives entered was significantly associated with receiving a recommendation. Conclusions A significant percentage of the general primary care population meet criteria for more intensive risk management. In particular 46% for monogenic hereditary and familial level disease risk. Adopting strategies to facilitate systematic risk assessment in primary care could have a significant impact on populations within the U.S. and even beyond. Trial registration Clinicaltrials.gov number NCT01956773, registered 10/8/2013.

Abstract
The discovery of genes underlying inherited predisposition to breast and ovarian cancer has revolutionized the ability to identify women at high risk for these diseases before they become affected. Women who are carriers of deleterious variants in these genes can undertake surveillance and prevention measures that have been shown to reduce morbidity and mortality. However, under current strategies, the vast majority of women carriers remain undetected until they become affected. In this review, we show that universal testing, particularly of the BRCA1 and BRCA2 genes, fulfills classical disease screening criteria. This is especially true for BRCA1 and BRCA2 in Ashkenazi Jews but is translatable to all populations and may include additional genes. Utilizing genetic information for large-scale precision prevention requires a paradigmatic shift in health-care delivery. To address this need, we propose a direct-to-patient model, which is increasingly pertinent for fulfilling the promise of utilizing personal genomic information for disease prevention.

Genetic testing in Poland and Ukraine: should comprehensive germline testing of BRCA1 and BRCA2 be recommended for women with breast and ovarian cancer? Genet Res (Camb) 2020; 102:e6.

Abstract
Purpose To characterize the spectrum of BRCA1 and BRCA2 pathogenic germline variants in women from south-west Poland and west Ukraine affected with breast or ovarian cancer. Testing in women at high risk of breast and ovarian cancer in these regions is currently mainly limited to founder mutations. Methods Unrelated women affected with breast and/or ovarian cancer from Poland (n = 337) and Ukraine (n = 123) were screened by targeted sequencing. Excluded from targeted sequencing were 34 Polish women who had previously been identified as carrying a founder mutation in BRCA1. No prior testing had been conducted among the Ukrainian women. Thus, this study screened BRCA1 and BRCA2 in the germline DNA of 426 women in total. Results We identified 31 and 18 women as carriers of pathogenic/likely pathogenic (P/LP) genetic variants in BRCA1 and BRCA2, respectively. We observed five BRCA1 and eight BRCA2 P/LP variants (13/337, 3.9%) in the Polish women. Combined with the 34/337 (10.1%) founder variants identified prior to this study, the overall P/LP variant frequency in the Polish women was thus 14% (47/337). Among the Ukrainian women, 16/123 (13%) women were identified as carrying a founder mutation and 20/123 (16.3%) were found to carry non-founder P/LP variants (10 in BRCA1 and 10 in BRCA2). Conclusions These results indicate that genetic testing in women at high risk of breast and ovarian cancer in Poland and Ukraine should not be limited to founder mutations. Extended testing will enhance risk stratification and management for these women and their families.

Abstract
NCCN Guidelines recommend BRCA genetic testing in individuals with a probability >5% of being a carrier. Nonetheless, the cost-effectiveness of testing individuals with no tumor family history is still debated, especially when BRCA testing is offered by the national health service. Our analysis evaluated the rate of BRCA pathogenic or likely-pathogenic variants in 159 triple-negative breast cancer (TNBC) patients diagnosed ≤60 years, and 109 luminal-like breast cancer (BC) patients diagnosed ≤35 without breast and/or ovarian family histories. In TNBC patients, BRCA mutation prevalence was 22.6% (21.4% BRCA1). Mutation prevalence was 64.2% ≤30 years, 31.8% in patients aged 31–40, 16.1% for those aged 41–50 and 7.9% in 51–60 s. A total of 40% of patients with estrogen receptors (ER) 1–9% were BRCA1 carriers. BRCA detection rate in early-onset BCs was 6.4% (4.6% BRCA2). Mutation prevalence was 0% between 0–25 years, 9% between 26–30 years and 6% between 31–35 years. In conclusion, BRCA testing is recommended in TNBC patients diagnosed ≤60 years, regardless of family cancer history or histotype, and by using immunohistochemical staining <10% for both ER and/PR. In luminal-like early-onset BC, a lower BRCA detection rate was observed, suggesting a role for other predisposing genes along with BRCA genetic testing.

Abstract
Introducción: el término secuenciación de nueva generación (NGS) hace referencia a las tecnologías diseñadas para analizar gran cantidad de ADN de forma masiva y paralela. Abordamos en esta revisión los conceptos básicos de estas tecnologías, las consideraciones de su uso clínico actual y perspectivas a futuro. Desarrollo: las pruebas basadas en NGS han revolucionado el estudio de los genomas pues permiten la lectura de millones de secuencias de ADN de forma masiva y paralela en un menor lapso de tiempo y a menor costo por base. Estas pruebas incluyen la secuenciación de panel de genes, la secuenciación completa del exoma y la secuenciación completa del genoma. El análisis de sus resultados es complejo y requiere de un proceso bioinformático y clínico exhaustivo para su adecuada interpretación. Las limitaciones de las pruebas NGS incluyen aspectos técnicos como la cobertura, profundidad y longitud de las secuencias, las cuales se pueden solventar implementando buenas prácticas de laboratorio. Conclusiones: las pruebas basadas en la secuenciación por NGS son herramientas diagnósticas que deben partir de una aproximación clínica adecuada para su uso razonado, correcta interpretación y toma de decisiones acertadas. Es de gran trascendencia que los médicos tengan la información básica para poder solicitar e interpretar estas pruebas dada su relevancia clínica actual.

Survey of primary care physicians' views about breast and ovarian cancer screening for true BRCA1/2 non-carriers. J Community Genet 2019; 11:205-213.

Abstract
Despite some controversy, true BRCA1/2 non-carriers are generally considered to be at an average risk for breast and ovarian cancer. Primary care physicians are then expected to encourage their non-carrier patients to adopt cancer screening practices appropriate to women of the same age in the general population. This study aimed to describe breast and ovarian cancer screening recommendations that primary care physicians would consider advisable for young true BRCA1/2 non-carriers. One hundred thirty-four family physicians and 123 gynecologists (response rate 45%) completed a cross-sectional mailed survey administered in the Province of Quebec, Canada. The survey included questions about basic genetic knowledge and screening recommendations for two fictitious cases (< 40 years), one carrier and one non-carrier, from a BRCA1/2 mutation-positive family. Screening exams considered advisable did not differ significantly between family physicians and gynecologists. More than 75% of physicians considered the cancer risks of true non-carriers to be comparable with that of the general population and 14% to be a little higher. Still, 53% would prescribe a biennial and or even an annual (27%) mammography to a non-carrier woman before the recommended starting age. Physician considerations of non-carriers' expectations or requests for screening were associated with more screening prescriptions. More than half of primary care physicians would recommend more mammography screenings than expected for a young true BRCA1/2 non-carrier. Personalized cancer risk assessment may help primary care physicians tailor screening of women from BRCA1/2 mutation-positive families and allow these women to make more informed choices regarding cancer risk management options.

Abstract
Background Germline genetic testing is standard practice in oncology. Outcomes of telephone disclosure of a wide range of cancer genetic test results, including multigene panel testing (MGPT) are unknown. Methods Patients undergoing cancer genetic testing were recruited to a multicenter, randomized, noninferiority trial (NCT01736345) comparing telephone disclosure (TD) of genetic test results with usual care, in-person disclosure (IPD) after tiered-binned in-person pretest counseling. Primary noninferiority outcomes included change in knowledge, state anxiety, and general anxiety. Secondary outcomes included cancer-specific distress, depression, uncertainty, satisfaction, and screening and risk-reducing surgery intentions. To declare noninferiority, we calculated the 98.3% one-sided confidence interval of the standardized effect; t tests were used for secondary subgroup analyses. Only noninferiority tests were one-sided, others were two-sided. Results A total of 1178 patients enrolled in the study. Two hundred eight (17.7%) participants declined random assignment due to a preference for in-person disclosure; 473 participants were randomly assigned to TD and 497 to IPD; 291 (30.0%) had MGPT. TD was noninferior to IPD for general and state anxiety and all secondary outcomes immediately postdisclosure. TD did not meet the noninferiority threshold for knowledge in the primary analysis, but it did meet the threshold in the multiple imputation analysis. In secondary analyses, there were no statistically significant differences between arms in screening and risk-reducing surgery intentions, and no statistically significant differences in outcomes by arm among those who had MGPT. In subgroup analyses, patients with a positive result had statistically significantly greater decreases in general anxiety with telephone disclosure (TD -0.37 vs IPD +0.87, P = .02). Conclusions Even in the era of multigene panel testing, these data suggest that telephone disclosure of cancer genetic test results is as an alternative to in-person disclosure for interested patients after in-person pretest counseling with a genetic counselor.

Barriers to the utilization of genetic testing and genetic counseling in patients with suspected hereditary breast and ovarian cancers. Proc (Bayl Univ Med Cent) 2019; 32:340-344. [PMID: 31384183 DOI: 10.1080/08998280.2019.1612702] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 04/19/2019] [Accepted: 04/22/2019] [Indexed: 12/26/2022] Open
Abstract
A heritable condition is the identified cause of cancer in 5% to 10% of women with breast cancer and in 25% of women with ovarian cancer. It is critical to identify patients at risk for inherited genetic mutations to implement risk-reducing screening and interventions; however, reports in the medical literature indicate that an alarming number of patients with inherited genetic mutations do not receive recommended genetic counseling, testing, or interventions. In order to improve outcomes for these high-risk patients, barriers to genetic testing and counseling must be identified. We analyzed approximately 200 patients seen at our institution with breast or ovarian cancer who met criteria of the National Comprehensive Cancer Network for genetic counseling and testing. Of these patients, almost 70% had appropriate genetic testing and counseling. Review of the remaining 30% revealed that the largest obstacle to receiving genetic testing and/or counseling was lack of referral from the treating oncologist. Of the patients diagnosed with a pathogenic heritable mutation, most underwent appropriate risk-reducing procedures and surveillance. Thus, the initial referral to genetic counseling is the most significant barrier for at-risk patients at our institution and likely in this population at large. Additional study is needed to identify ways to improve appropriate use of genetic testing and counseling.

Abstract
Children's literacy about the genetics of late-onset hereditary breast/ovarian cancer (HBOC) often develops through conversations with parents about BRCA gene testing and adults' cancer diagnoses. These conversations may promote early understanding of HBOC, but the long-term impact on children's psychosocial adjustment remains unclear. We investigated cancer genetic health communication in BRCA-tested families to consider benefits, risks, and moderating influences on children's understanding and well-being. Adolescent and young adult children (ages 12-24) of mothers who underwent BRCA testing 1+ years previously completed qualitative interviews that were transcribed, coded (intercoder K ≥ .70), and content-analyzed (N = 34). Children readily recalled conversations about BRCA testing and HBOC (100%) that they considered important (94%), but implications for children were ambiguous and obfuscated their concerns. Psychosocial impacts were muted, multifaceted, and displayed a range of favorable (82%), neutral (71%), and unfavorable (59%) response-frequently co-occurring within the same child over different aspects (e.g., medical, concern for self and others). Children verbalized active (50%) and avoidant (38%) coping strategies: about 1:5 endorsed transient thoughts about vulnerability to HBOC, 1:3 had not further considered it, and all reported specific actions they had or would undertake to remain healthy (e.g., diet/exercise). A majority (94%) of children had or would consider genetic testing for themselves, usually later in life (59%). Long-term outcomes highlighted benefits (awareness of HBOC, psychological hardiness, healthier lifestyle behaviors), as well as some psychosocial concerns that could be managed through interventions promoting genetic health literacy.

Abstract
Patients who carry the BRCA1 and BRCA2 gene mutations have an underlying genetic predisposition for breast and ovarian cancers. These deleterious genetic mutations are the most common genes implicated in hereditary breast and ovarian cancers. This monograph summarizes the evidence behind current screening recommendations, reviews imaging protocols specific to this patient population, and illustrates some of the imaging nuances of breast and ovarian cancers in this clinical setting.

Abstract
Loss-of-function germline mutations in the PALB2 gene are associated with an increase of breast cancer risk. The purpose of this study was to characterise the spectrum of PALB2 mutations in women affected with breast or ovarian cancer from South-West Poland and West Ukraine. We applied Hi-Plex, an amplicon-based enrichment method for targeted massively parallel sequencing, to screen the coding exons and proximal intron–exon junctions of PALB2 in germline DNA from unrelated women affected with breast cancer (n = 338) and ovarian cancer (n = 89) from Poland (n = 304) and Ukraine (n = 123). These women were at high-risk of carrying a genetic predisposition to breast and/or ovarian cancer due to a family history and/or early-onset disease. Targeted-sequencing identified two frameshift deletions: PALB2:c.509_510del; p.R170Ifs in three women affected with breast cancer and PALB2:c.172_175del;p.Q60Rfs in one woman affected with ovarian cancer. A number of other previously described missense (some predicted to be damaging by PolyPhen-2 and CADD) and synonymous mutations were also identified in this population. This study is consistent with previous reports that PALB2:c.509_510del and PALB2:c.172_175del are recurrent mutations associated with breast cancer predisposition in Polish women with a family history of the disease. Our study contributes to the accumulating evidence indicating that PALB2 should be included in genetic testing for breast cancer susceptibility in these populations to enhance risk assessment and management of women at high-risk of developing breast cancer. This data could also contribute to ongoing work that is assessing the possible association between ovarian cancer risk and PALB2 mutations for which there is currently no evidence.

Abstract
Telephone disclosure of cancer genetic test results is noninferior to in-person disclosure. However, how patients who prefer in-person communication of results differ from those who agree to telephone disclosure is unclear but important when considering delivery models for genetic medicine. Patients undergoing cancer genetic testing were recruited to a multicenter, randomized, noninferiority trial (NCT01736345) comparing telephone to in-person disclosure of genetic test results. We evaluated preferences for in-person disclosure, factors associated with this preference and outcomes compared to those who agreed to randomization. Among 1178 enrolled patients, 208 (18%) declined randomization, largely given a preference for in-person disclosure. These patients were more likely to be older (P = 0.007) and to have had multigene panel testing (P < 0.001). General anxiety (P = 0.007), state anxiety (P = 0.008), depression (P = 0.011), cancer-specific distress (P = 0.021) and uncertainty (P = 0.03) were higher after pretest counseling. After disclosure of results, they also had higher general anxiety (P = 0.003), depression (P = 0.002) and cancer-specific distress (P = 0.043). While telephone disclosure is a reasonable alternative to in-person disclosure in most patients, some patients have a strong preference for in-person communication. Patient age, distress and complexity of testing are important factors to consider and requests for in-person disclosure should be honored when possible.

Abstract
PURPOSE BRCA1/BRCA2 predictive test negatives are proven noncarriers of a BRCA1/BRCA2 mutation that is carried by their relatives. The risk of developing breast cancer (BC) or epithelial ovarian cancer (EOC) in these women is uncertain. The study aimed to estimate risks of invasive BC and EOC in a large cohort of BRCA1/BRCA2 predictive test negatives. METHODS We used cohort analysis to estimate incidences, cumulative risks, and standardized incidence ratios (SIRs). RESULTS A total of 1,895 unaffected women were eligible for inclusion in the BC risk analysis and 1,736 in the EOC risk analysis. There were 23 incident invasive BCs and 2 EOCs. The cumulative risk of invasive BC was 9.4% (95% confidence interval (CI) 5.9-15%) by age 85 years and the corresponding risk of EOC was 0.6% (95% CI 0.2-2.6%). The SIR for invasive BC was 0.93 (95% CI 0.62-1.40) in the overall cohort, 0.85 (95% CI 0.48-1.50) in noncarriers from BRCA1 families, and 1.03 (95% CI 0.57-1.87) in noncarriers from BRCA2 families. The SIR for EOC was 0.79 (95% CI 0.20-3.17) in the overall cohort. CONCLUSION Our results did not provide evidence for elevated risks of invasive BC or EOC in BRCA1/BRCA2 predictive test negatives.

Abstract
BACKGROUND Historically, groups that are most susceptible to health and healthcare disparities have been underrepresented in medical research. It is imperative to explore approaches that can facilitate the recruitment of underrepresented individuals into research studies. METHODS Two approaches, hospital and community-based recruitment (CBR), were developed and implemented over 36 months to study the genetics of hereditary breast cancer and associated cancers in Alabama, a medically underserved state with double the national percentage of self-identifying African Americans, establishing the Alabama Hereditary Cancer Cohort. RESULTS Overall, 242 individuals enrolled. This included 84 cancer probands through hospital recruitment, as well as 76 probands and 82 family members through CBR. Eighty-one percent of the study participants' counties of residence are completely medically underserved. Furthermore, African Americans represent 26% of the hospital probands compared to 49% and 70% of the probands and family members who, respectively, enrolled through CBR. CONCLUSION Although both recruitment mechanisms were instrumental, the unique trust building, educational, and traveling components of CBR facilitated the enrollment of African Americans resulting in large families for genetic analyses. The ultimate goal is to gain insight from these rudimentary efforts in order to expand recruitment and accrue a unique resource for cancer genetics research.

Simultaneous detection of BRCA mutations and large genomic rearrangements in germline DNA and FFPE tumor samples. Oncotarget 2018; 7:61845-61859.

Abstract
The development of breast and ovarian cancer is strongly connected to the inactivation of the BRCA1 and BRCA2 genes by different germline and somatic alterations, and their diagnosis has great significance in targeted tumor therapy, since recently approved PARP inhibitors show high efficiency in the treatment of BRCA-deficient tumors. This raises the need for new diagnostic methods that are capable of performing an integrative mutation analysis of the BRCA genes not only from germline DNA but also from formalin-fixed and paraffin-embedded (FFPE) tumor samples. Here we describe the development of such a methodology based on next-generation sequencing and a new bioinformatics software for data analysis. The diagnostic method was initially developed on an Illumina MiSeq NGS platform using germline-mutated stem cell lines and then adapted for the Ion Torrent PGM NGS platform as well. We also investigated the usability of NGS coverage data for the detection of copy number variations and exon deletions as a replacement of the conventional MLPA technique. Finally, we tested the developed workflow on FFPE samples from breast and ovarian cancer patients. Our method meets the sensitivity and specificity requirements for the genetic diagnosis of breast and ovarian cancers both from germline and FFPE samples.

FANCM and RECQL genetic variants and breast cancer susceptibility: relevance to South Poland and West Ukraine. BMC MEDICAL GENETICS 2018; 19:12. [PMID: 29351780 PMCID: PMC5775547 DOI: 10.1186/s12881-018-0524-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Accepted: 01/09/2018] [Indexed: 12/17/2022]
Abstract
Background FANCM and RECQL have recently been reported as breast cancer susceptibility genes and it has been suggested that they should be included on gene panel tests for breast cancer predisposition. However, the clinical value of testing for mutations in RECQL and FANCM remains to be determined. In this study, we have characterised the spectrum of FANCM and RECQL mutations in women affected with breast or ovarian cancer from South-West Poland and West Ukraine. Methods We applied Hi-Plex, an amplicon-based enrichment method for targeted massively parallel sequencing, to screen the coding exons and proximal intron-exon junctions of FANCM and RECQL in germline DNA from unrelated women affected with breast cancer (n = 338) and ovarian cancer (n = 89) from Poland (n = 304) and Ukraine (n = 123). These women were at high-risk of carrying a genetic predisposition to breast and/or ovarian cancer due to a family history and/or early-onset disease. Results Among 427 women screened, we identified one carrier of the FANCM:c.1972C > T nonsense mutation (0.23%), and two carriers of the frameshift insertion FANCM:c.1491dup (0.47%). None of the variants we observed in RECQL were predicted to be loss-of-function mutations by standard variant effect prediction tools. Conclusions Our study of the Polish and Ukrainian populations has identified a carrier frequency of truncating mutations in FANCM consistent with previous reports. Although initial reports suggesting that mutations in RECQL could be associated with increased breast cancer risk included women from Poland and identified the RECQL:c.1667_1667 + 3delAGTA mutation in 0.23–0.35% of breast cancer cases, we did not observe any carriers in our study cohort. Continued screening, both in research and diagnostic settings, will enable the accumulation of data that is needed to establish the clinical utility of including RECQL and FANCM on gene panel tests.

Abstract
BACKGROUND In families with a proven BRCA1/2 mutation, women not carrying the familial mutation should follow the cancer screening recommendations applying to women in the general population. In the present study, we evaluated the cancer screening practices of unaffected noncarriers from families with a proven BRCA mutation, and we assessed the role of family history in their screening practices. METHODS Self-report data were provided retrospectively by 220 unaffected female noncarriers for periods of up to 10 years (mean: 4.3 years) since disclosure of their BRCA1/2 genetic test result. A ratio for the annual frequency of breast and ovarian cancer screening exams (mammography, breast ultrasonography, breast magnetic resonance imaging, transvaginal or pelvic ultrasound, cancer antigen 125 testing) was calculated as number of screening exams divided by the number of years in the individual observation period. RESULTS The annual average for mammography exams was 0.15, 0.4, 0.56, and 0.71 in women 30-39, 40-49, 50-59, and 60-69 years of age respectively. The uptake of other breast and ovarian cancer screening exams was very low. Mammography and breast ultrasonography and magnetic resonance imaging were generally more frequent among participants with at least 1 first-degree relative affected by breast cancer. CONCLUSIONS In most noncarriers, screening practices are consistent with the guidelines concerning women in the general population. When noncarriers adopt screening behaviours that are different from those that would be expected for average-risk women, those behaviours are influenced by their familial cancer history. IMPACT Decision tools might help female noncarriers to be involved in their follow-up in accordance with their genetic status and their family history, while taking into account the benefits and disadvantages of cancer screening.

Abstract
Technological advances realized through next-generation sequencing technologies coupled with the loss of the ability to patent genes have led to reduction in costs for genetic testing. As a result, more people are being identified with inherited breast cancer syndromes that may affect recommendations for surveillance and risk reduction. Surgeons, at the forefront for patients newly diagnosed with breast cancer, must keep current with the changing landscape of genetics to continue to provide appropriate counsel and care. This article provides an overview of individuals at risk for inherited cancer predisposition and recommendations for surveillance and management.

Abstract
BACKGROUND A family history of liver cancer increases the risk of developing hepatocellular carcinoma (HCC) by 2-fold to 10-fold among patients with chronic hepatitis B virus (HBV). Previous genome-wide association studies have identified many possible susceptible loci associated with sporadic HBV-related HCC. However, despite family history being a well-known risk factor for HBV-related HCC, to the authors' knowledge its genetic mechanisms and associating loci remain largely unknown or unexplored, most likely due to the relative rarity of familial HCC and the difficulty of sample collection. METHODS The authors conducted a genome-wide association study with 139 male cases with familial HBV-related HCC and 139 non-HCC male controls with chronic HBV. The results were corroborated further with an independent cohort of 101 patients with familial HBV-related HCC and comparison with both the 1000 Genomes Project and the Taiwan Biobank. RESULTS A total of 51 risk single-nucleotide polymorphisms (P≤1E-04) were identified in the association analyses, which included 2 clusters of associated single-nucleotide polymorphisms and haplotypes at 1q25.3 (glutamate-ammonia ligase [GLUL]/transmembrane epididymal protein 1 [TEDDM1]/long intergenic non-protein-coding RNA 272 [LINC00272]/regulator of G-protein signaling-like 1 [RGSL1]) and 17q11.2 (solute carrier family 13 member 2 [SLC13A2]/forkhead box N1 [FOXN1]). Both the GLUL and SLC13A2/FOXN1 haplotypes have large effect sizes and were found to be different from those found from genome-wide association studies of sporadic HCCs. CONCLUSIONS To the authors' knowledge, the current study is the first genome-wide association study to identify genetic factors for familial HBV-related HCC. The results identified 2 large effect susceptible haplotypes located at GLUL and SLC13A2/FOXN1. The current study findings also suggest different genetic susceptibility between familial and sporadic HBV-related HCC. Cancer 2017;123:3966-76. © 2017 American Cancer Society.

Abstract
Canines are excellent models for cancer studies due to their similar physiology and genomic sequence to humans, companion status and limited intra‐breed heterogeneity. Due to their affliction to mammary cancers, canines can serve as powerful genetic models of hereditary breast cancers. Variants within known human breast cancer susceptibility genes only explain a fraction of familial cases. Thus, further discovery is necessary but such efforts have been thwarted by genetic heterogeneity. Reducing heterogeneity is key, and studying isolated human populations have helped in the endeavour. An alternative is to study dog pedigrees, since artificial selection has resulted in extreme homogeneity. Identifying the genetic predisposition to canine mammary tumours can translate to human discoveries – a strategy currently underutilized. To explore this potential, we reviewed published canine mammary tumour genetic studies and proposed benefits of next generation sequencing canine cohorts to facilitate moving beyond incremental advances.

Abstract
Genetics has made great progress in the past decades, and prenatal diagnosis, predictive genetic testing, and genetic counseling have drawn the limelight of public attention. Because the subject of genetic counseling is of crucial consequence for both the short and long term, its ethical aspects are paramount. The question is whether mankind is mature enough to use this extraordinary knowledge in the right way for the benefit of the society. In the center of ethical questions is the comprehensiveness of information provided to the couples or patients and counseling them about results and making informed educated decisions. In addition, it is crucial how sensitive personal information is treated and whether and how it should be made public.

Abstract
Patients with triple-negative breast cancer (TNBC), defined as lacking expression of the estrogen and progesterone receptors (ER/PR) and amplification of the HER2 oncogene, often have a more aggressive disease course than do patients with hormone receptor-positive breast cancer, including higher rates of visceral and central nervous system metastases, early cancer recurrences and deaths. Triple-negative breast cancer is associated with a young age at diagnosis and both African and Ashkenazi Jewish ancestry, the latter due to three common founder mutations in the highly penetrant cancer susceptibility genes BRCA1 and BRCA2 (BRCA1/2). In the past decade, there has been a surge both in genetic testing technology and in patient access to such testing. Advances in genetic testing have enabled more rapid and less expensive commercial sequencing than could be imagined only a few years ago. Massively parallel, next-generation sequencing allows the simultaneous analysis of many different genes. Studies of TNBC patients in the current era have revealed associations of TNBC with mutations in several moderate penetrance breast cancer susceptibility genes, including PALB2, BARD1, BRIP1, RAD51C and RAD51D. Interestingly, many of these genes, like BRCA1/2, are involved in homologous recombination DNA double-stranded repair. In this review, we summarize the current understanding of pathogenic germline gene mutations associated with TNBC and the early detection and prevention strategies for women at risk of developing this high-risk breast cancer subtype. Furthermore, we discuss recent the advances in targeted therapies for TNBC patients with a hereditary predisposition, including the role of poly (ADP-ribose) polymerase (PARP) inhibitors in BRCA1/2 mutation-associated breast cancers.

Abstract
The BRCA Gist Intelligent Tutoring System helps women understand and make decisions about genetic testing for breast cancer risk. BRCA Gist is guided by Fuzzy-Trace Theory, (FTT) and built using AutoTutor Lite. It responds differently to participants depending on what they say. Seven tutorial dialogues requiring explanation and argumentation are guided by three FTT concepts: forming gist explanations in one's own words, emphasizing decision-relevant information, and deliberating the consequences of decision alternatives. Participants were randomly assigned to BRCA Gist, a control, or impoverished BRCA Gist conditions removing gist explanation dialogues, argumentation dialogues, or FTT images. All BRCA Gist conditions performed significantly better than controls on knowledge, comprehension, and risk assessment. Significant differences in knowledge, comprehension, and fine-grained dialogue analyses demonstrate the efficacy of gist explanation dialogues. FTT images significantly increased knowledge. Providing more elements in arguments against testing correlated with increased knowledge and comprehension.

Abstract
Inherited genetic risk factors contribute toward breast cancer (BC) onset. BC risk variants can be divided into three categories of penetrance (high, moderate, and low) that reflect the probability of developing the disease. Traditional BC susceptibility gene discovery approaches that searched for high- and moderate-risk variants in familial BC cases have had limited success; to date, these risk variants explain only ∼30% of familial BC cases. Next-generation sequencing technologies can be used to search for novel high and moderate BC risk variants, and this manuscript reviews 12 familial BC whole-exome sequencing efforts. Study design, filtering strategies, and segregation and validation analyses are discussed. Overall, only a modest number of novel BC risk genes were identified, and 90% and 97% of the exome-sequenced families and cases, respectively, had no BC risk variants reported. It is important to learn from these studies and consider alternate strategies in order to make further advances. The discovery of new BC susceptibility genes is critical for improved risk assessment and to provide insight toward disease mechanisms for the development of more effective therapies.

Abstract
Identifying unaffected women with a BRCA mutation can have a significant individual and population health impact on morbidity and mortality if these women adhere to guidelines for managing cancer risk. But, little is known about whether such women are adherent to current guidelines. We conducted telephone surveys of 97 unaffected BRCA mutation carriers who had genetic counseling at least one year prior to the survey to assess adherence to current guidelines, factors associated with adherence, and common reasons for performing and not performing recommended risk management. More than half of participants reported being adherent with current risk management recommendations for breast cancer (69 %, n = 67), ovarian cancer (82 %, n = 74) and both cancers (66 %, n = 64). Older age (OR = 10.53, p = 0.001), white race (OR = 8.93, p = 0.019), higher breast cancer genetics knowledge (OR = 1.67, p = 0.030), higher cancer-specific distress (OR = 1.07, p = 0.002) and higher physical functioning (OR = 1.09, p = 0.009) were significantly associated with adherence to recommended risk management for both cancers. Responses to open-ended questions about reasons for performing and not performing risk management behaviors indicated that participants recognized the clinical utility of these behaviors. Younger individuals and those with lower physical functioning may require targeted interventions to improve adherence, perhaps in the setting of long-term follow-up at a multi-disciplinary hereditary cancer clinic.

Abstract
PURPOSE Originally, BRCA testing was used for risk assessment and prevention strategies for breast and ovarian cancer. Nowadays, BRCA status may influence therapeutic decision making at cancer diagnosis. Our objective was to analyze whether the medical advances have changed the burden and pattern of referral, and the pathogenic mutation detection rate. METHODS We included 969 probands from our hereditary cancer registry who undertook a full BRCA analysis between 2006 and 2014. Chi-square tests were used to compare categorical variables. RESULTS The number of genetic tests have raised from 28 to 170, representing a sixfold increase. In 2006, we tested 1.6 relatives/proband while this proportion was four in 2014. Overall, 20 % harbored a deleterious mutation and 11 % had a variant of unknown significance (VUS). There has been a downward trend in the detection rate of VUS. Testing patients with breast cancer during neoadjuvancy has raised from 4 to 25 % (p = 0.002), while testing them during remission has decreased from 79 to 29 % (p < 0.001). The proportion of patients assessed during the first 6 months after their cancer diagnosis has increased from 3 to 34 % (p = 0.001). Risk reducing mastectomy and salpingoophorectomy have raised from 0 to 24 %, and from 36 to 65 %, respectively. CONCLUSIONS BRCA testing has experienced a sixfold increase, the number of relatives being tested has doubled, and the test is being performed at earlier phases of the disease. It is necessary to adequate the health resources to preserve the BRCA genetic counseling quality while incorporating BRCA testing for therapeutic decision making.

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

Abstract
PURPOSE Most women from BRCA1/2 mutation-positive families who did not inherit the familial mutation have breast and ovarian cancer risks similar to those of women of the same age in the general population. However, recent studies suggest that some of these noncarriers may exhibit screening practices that may be considered as excessive compared to general population screening guidelines. Reasons for such tendencies remain largely unknown. This study aims to better understand how the implications of a noncarrier status are explained to these women and how their own realization of this status affects their screening behaviors. METHODS A qualitative study was conducted with five focus groups (n = 28) in Quebec City and Montreal, Canada. RESULTS Thematic analysis of the discussions highlighted four major themes: (i) acquiring a noncarrier identity takes place progressively; (ii) noncarriers show a range of opinions about screening; (iii) noncarriers have mixed feelings about the follow-up by their physicians and gynecologists; and (iv) noncarriers need more information in a context where genetics progresses ever more rapidly. CONCLUSION Our results provide novel insights regarding the physician-patient interaction and the organizational aspects of the health-care system that may significantly impact the cancer screening practices of BRCA1/2 noncarriers.Genet Med 18 6, 627-634.

Abstract
The traditional model of providing cancer predictive testing services is changing. Many genetic centres are now offering a choice to patients in how they receive their results instead of the typical face-to-face disclosure. In view of this shift in practice and the increasing demand on the ROI cancer predictive testing service, a 2 year retrospective study on patient preference in how to receive a Breast Cancer (BRCA) predictive result was carried out. Results showed that 71.7 % of respondents would have liked to have the option of obtaining their results by telephone or by letter. However, when asked about their actual experience of BRCA predictive results disclosure 40.6 % did still value the face-to-face contact, while 44.9 % would still have preferred to receive results by either post or telephone. No significant difference was found between males and females (p > 0.05) and those who tested negative or positive for the BRCA mutation (p > 0.05) in wanting a choice in how their results were disclosed. While the majority expressed a wish to have a choice in how to receive their results, it is important not to underestimate the value of a face-to-face encounter in these circumstances.

Abstract
OBJECTIVE The availability of next-generation sequencing and identification of multiple cancer-related genes has caused a shift away from single gene testing towards multi-gene panel testing for hereditary cancer syndromes. However, the utility of panels in individuals who previously underwent non-informative genetic screening has yet to be evaluated. We aim to evaluate the use of rescreening and results of multi-gene panels in this rescreened population. METHODS We reviewed the medical records for patients who had previously undergone genetic testing and then underwent multi-gene panel testing at a single institution between 9/2013 and 11/2014. RESULTS One hundred and twenty-seven patients with prior genetic testing underwent multi-gene panels. One hundred and four patients (82%) had a history of cancer and 118 (93%) had at least one family member with cancer. On primary testing, no pathogenic mutations were detected and 10 patients (8%) were found to have variants of uncertain significance (VUS). On repeat multi-gene panel testing, nine patients (7%) were found to have a pathogenic mutation and 53 patients (42%) were VUS not identified on prior testing. CONCLUSIONS Seven percent of patients with non-informative primary testing were found to have a pathogenic mutation with multi-gene panels, suggesting that there is a potential benefit to be gained from rescreening. However, 42% of patients were found to have new VUS with panels, a result that can cause patients anxiety without clear clinical implications.

Abstract
OBJECTIVE The aim of our study was to determine the rate of participation in genetic testing, to determine the reasons for non-participation and to identify the factors affecting participation in BRCA genetic testing for high-risk patients. METHODS This study was performed through a retrospective review of 804 individuals who underwent genetic counseling for BRCA1/2 gene mutations at Seoul National University Bundang Hospital between July 2003 and September 2012. RESULTS In total, 728 (90.5%) individuals underwent BRCA1/2 mutation screening after the initial genetic counseling; 88.2% of 647 probands and 100% of 157 family members were screened. In multivariate analysis, family history of breast cancer and younger age were independent variables affecting participation in genetic testing. Of the 132 people who initially declined genetic testing, 58 (43.9%) postponed the decision, 30 (22.7%) needed time to discuss the issue with family members, 22 (16.7%) did not want to know if they had a BRCA1/2 mutation, and 22 (16.7%) declined the test because of financial problems. When analyzing refusal of testing according to the time period before and after the implementation of national health insurance coverage for BRCA1/2 genetic testing, the critical reason given for refusal was different. After insurance coverage, refusal for financial reason was decreased from 61.1 to 9.6%. CONCLUSIONS A family history of breast cancer and a younger age were important factors associated with participation in genetic testing. National health insurance decreased the proportion of individuals who did not participate in testing owing to a financial reason. In genetic counseling, we have to understand these issues and consider several factors that may influence an individual's decision to be tested.

Abstract
Background Dissemination of genetic testing for disease susceptibility, one application of “personalized medicine”, holds the potential to empower patients and providers through informed risk reduction and prevention recommendations. Genetic testing has become a standard practice in cancer prevention for high-risk populations. Heightened consumer awareness of “cancer genes” and genes for other diseases (eg, cardiovascular and Alzheimer’s disease), as well as the burgeoning availability of increasingly complex genomic tests (ie, multi-gene, whole-exome and -genome sequencing), has escalated interest in and demand for genetic risk assessment and the specialists who provide it. Increasing demand is expected to surpass access to genetic specialists. Thus, there is urgent need to develop effective and efficient models of delivery of genetic information that comparably balance the risks and benefits to the current standard of in-person communication. Objective The aim of this pilot study was to develop and evaluate a theoretically grounded and rigorously developed protocol for telephone communication of BRCA1/2 (breast cancer) test results that might be generalizable to genetic testing for other hereditary cancer and noncancer syndromes. Methods Stakeholder data, health communication literature, and our theoretical model grounded in Self-Regulation Theory of Health Behavior were used to develop a telephone communication protocol for the communication of BRCA1/2 genetic test results. Framework analysis of selected audiotapes of disclosure sessions and stakeholders’ feedback were utilized to evaluate the efficacy and inform refinements to this protocol. Results Stakeholder feedback (n=86) and audiotapes (38%, 33/86) of telephone disclosures revealed perceived disadvantages and challenges including environmental factors (eg, non-private environment), patient-related factors (eg, low health literacy), testing-related factors (eg, additional testing needed), and communication factors (eg, no visual cues). Resulting modifications to the communication protocol for BRCA1/2 test results included clarified patient instructions, scheduled appointments, refined visual aids, expanded disclosure checklist items, and enhanced provider training. Conclusions Analyses of stakeholders’ experiences and audiotapes of telephone disclosure of BRCA1/2 test results informed revisions to communication strategies and a protocol to enhance patient outcomes when utilizing telephone to disclose genetic test results.

Abstract
OBJECTIVES This paper aims to identify relevant potential predictors of medical genetic counseling for breast cancer (MGC-BC) in primary care and to develop a comprehensive questionnaire to study MGC-BC. METHODS A scoping review was conducted to identify the predictors of MGC-BC among primary care physicians. Relevant articles were identified in selected databases (PubMed, Embase, CINAHL, ISI Web of Science, PsycINFO, and Cochrane CENTRAL) and 4 selected relevant electronic journals. RESULTS An inductive analysis of the 193 quantitatively tested variables, conducted by 3 researchers, showed that 6 conceptual categories of determinants, namely (1) demographic, (2) organizational, (3) experiential, (4) professional, (5) psychological, and (6) cognitive, influence MGC-BC practices. CONCLUSION There is a scarcity of literature addressing the medical behavior determinants of MGC-BC. Future research is needed to identify effective strategies put into action to support the integration of MGC-BC in primary care medical practices and routines. However, our results shed light on 2 levels of actions that could improve genetic counseling services in primary care: (1) medical training and educational efforts emphasizing family history collection (individual level), and (2) clarification of roles and responsibilities in ordering and referral practices in genetic counseling and genetic testing for better healthcare management (organizational level).

Abstract
BACKGROUND . Many healthy women consider genetic testing for breast cancer risk, yet BRCA testing issues are complex. OBJECTIVE . To determine whether an intelligent tutor, BRCA Gist, grounded in fuzzy-trace theory (FTT), increases gist comprehension and knowledge about genetic testing for breast cancer risk, improving decision making. DESIGN . In 2 experiments, 410 healthy undergraduate women were randomly assigned to 1 of 3 groups: an online module using a Web-based tutoring system (BRCA Gist) that uses artificial intelligence technology, a second group read highly similar content from the National Cancer Institute (NCI) Web site, and a third that completed an unrelated tutorial. INTERVENTION . BRCA Gist applied FTT and was designed to help participants develop gist comprehension of topics relevant to decisions about BRCA genetic testing, including how breast cancer spreads, inherited genetic mutations, and base rates. MEASURES . We measured content knowledge, gist comprehension of decision-relevant information, interest in testing, and genetic risk and testing judgments. RESULTS . Control knowledge scores ranged from 54% to 56%, NCI improved significantly to 65% and 70%, and BRCA Gist improved significantly more to 75% and 77%, P < 0.0001. BRCA Gist scored higher on gist comprehension than NCI and control, P < 0.0001. Control genetic risk-assessment mean was 48% correct; BRCA Gist (61%) and NCI (56%) were significantly higher, P < 0.0001. BRCA Gist participants recommended less testing for women without risk factors (not good candidates; 24% and 19%) than controls (50%, both experiments) and NCI (32%), experiment 2, P < 0.0001. BRCA Gist testing interest was lower than in controls, P < 0.0001. LIMITATIONS . BRCA Gist has not been tested with older women from diverse groups. CONCLUSIONS . Intelligent tutors, such as BRCA Gist, are scalable, cost-effective ways of helping people understand complex issues, improving decision making.

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