Pre‐test genetic counseling services for hereditary breast and ovarian cancer delivered by non‐genetics professionals in the state of Florida

Genetic counseling and testing for hereditary breast and ovarian cancer now includes practitioners from multiple healthcare professions, specialties, and settings. This study examined whether non‐genetics professionals (NGPs) perform guideline‐based patient intake and informed consent before genetic testing. NGPs offering BRCA testing services in Florida (n = 386) were surveyed about clinical practices. Among 81 respondents (response rate = 22%), approximately half reported: sometimes scheduling a separate session for pre‐test counseling lasting 11–30 min prior to testing, discussing familial implications of testing, benefits and limitations of risk management options, and discussing the potential psychological impact and insurance‐related issues. Few constructed a three‐generation pedigree, discussed alternative hereditary cancer syndromes, or the meaning of a variant result. This lack of adherence to guideline‐based practice may result in direct harm to patients and their family members. NGPs who are unable to deliver guideline adherent cancer genetics services should focus on identification and referral of at‐risk patients to in person or telephone services provided by genetics professionals.     

Knowledge About Genetic Risk for Breast Cancer and Perceptions of Genetic Testing in a Sociodemographically Diverse Sample

Informed consent for genetic testing for breast–ovarian cancer susceptibility requires that women understand basic concepts about the inheritance of cancer susceptibility and the benefits and risks associated with genetic testing. Women awaiting routine medical services (N = 220) were surveyed about their knowledge of breast cancer and cancer genetics and their perceptions of genetic testing and personal risk. There were no racial differences in median income or mean level of education. Compared to Caucasian women, African American women knew significantly less about breast cancer and about genetic risk for breast cancer. African American women had different psychological, social, and economic concerns as evidenced by how they weighted the benefits and risks of genetic testing. This study is the first to assess several dimensions of informed consent for genetic testing among a sociodemographically diverse group. The findings should enable health professionals to target the African American and lower-income populations with the appropriate education and counseling.     

Letting the family know: balancing ethics and effectiveness when notifying relatives about genetic testing for a familial disorder

Objective

To increase the awareness among at risk relatives of the availability of genetic testing for a familial disorder while respecting their autonomy and privacy.

Methods

This was a comparison of preintervention and postintervention cohorts of families carried out in a state wide clinical service providing genetic counselling and testing for people at risk of familial adult onset cancer. Unaffected relatives who were not clients of the service in 74 kindreds with familial mutations causing familial breast and ovarian cancer, hereditary non‐polyposis colorectal cancer, or Cowden syndrome were included in the study. In the baseline cohort (41 kindreds), family members who were clients of the clinical service and had been shown to be carriers of mutations were asked to advise relatives that genetic testing was available. In the intervention cohort (33 kindreds), the clinical service obtained consent to advise at risk relatives by letter that genetic testing was available. The main outcome measures were: (a) proportion of unaffected first and second degree relatives of the proband in each family whose genetic status was clarified within 2 years of the mutation being identified in the family, and (b) concerns regarding privacy and autonomy voiced by relatives receiving these letters.

Results

In the baseline cohort, the average proportion of relatives in each family whose genetic status was clarified was 23%. In the intervention cohort, the average proportion of relatives in each family whose genetic status was clarified was 40% (p = 0.001). None of the relatives in the intervention cohort complained of a breach of privacy or autonomy.

Conclusion

Clinical services can take an effective and proactive approach to notifying relatives who are not their clients of the availability of genetic testing without compromising principles of privacy and autonomy.     

Psychological functioning in African American women at an increased risk of hereditary breast and ovarian cancer

Despite attention to psychological issues during genetic counselling and testing for hereditary breast and ovarian cancer risk, limited information is available on cancer-specific distress among African American women being targeted for participation in counselling and testing. Therefore, the purpose of this study is to examine cancer-specific distress in African American women at an increased risk of hereditary breast and ovarian cancer and to identify factors having significant associations with distress in this population. Respondents were 141 African American women identified for participation in genetic counselling and testing for BRCA1/2 mutations. Overall, respondents reported moderate levels of cancer-specific distress. Younger age (coefficient=6.0, p=0.001), being unemployed (coefficient=-5.0, p=0.01), and having a personal history of cancer (coefficient=5.0, p=0.02) had significant associations with intrusion. Younger age was also associated significantly with greater avoidance (r=6.0, p=0.02). These results suggest that African American women aged 50 and younger, those who are unemployed and women with a personal history of breast or ovarian cancer may be the most vulnerable to experiencing elevated levels of distress during genetic counselling and testing. Greater attention to psychological issues, including concerns about cancer and cancer risks, may be needed during genetic counselling and testing for BRCA1/2 mutations with these women.     

Sociodemographic,psychosocial and clinical factors associated with uptake of genetic counselling for hereditary cancer: a systematic review

Evidence suggests that a significant proportion of individuals referred to cancer genetic counselling (GC) do not attend, and thus may not be engaged in adequate cancer risk management. We aimed to review the literature to better understand barriers to accessing GC and how they may be overcome. We conducted a systematic literature search for articles examining factors influencing cancer GC uptake as well as motivators and barriers to GC attendance. Factors were categorised as sociodemographic, psychosocial or clinical. The literature search identified 1413 citations, 35 of which met the inclusion criteria. GC uptake ranged from 19% to 88%. With the exceptions of education level, socioeconomic status, cancer‐specific distress, personal cancer diagnosis and actual and perceived risk of cancer, support was lacking for most sociodemographic, clinical and psychosocial factors as predictors of GC uptake. Cost and logistical barriers, emotional concerns, family concerns and low perceived personal relevance were reported as important considerations for those declining GC. We conclude that there is poor understanding of GC and a lack of decision support among those referred to GC. Research into ways of providing education and support to referred individuals will be important as the scope and availability of GC and genetic testing broaden.     

Variability and inequity in testing of somatic tissue for hereditary cancer: a survey of UK clinical practice

A growing body of literature demonstrates the benefits of molecular pathological investigations of tumour material in the identification of individuals with hereditary non-polyposis colorectal cancer and debates the best detection strategies. This testing is novel as it is the first widespread use of somatic tissue testing to inform genetic analysis and requires the co-ordination of both histopathology and molecular genetics laboratories. However, the clinical use and experience of microsatellite instability (MSI) testing and immunohistochemical analysis have not been reported. A respondent from every cancer genetics centre in the UK (n= 24, response rate 100%) and laboratory performing MSI testing (n= 5, response rate 100%) was interviewed by telephone to ascertain test availability, testing methods, eligibility criteria and post-test management. Twenty centres (83%) offer eligible clients at least one form of tumour testing, and all use tumour testing to determine who should have access to germ line genetic testing. However, no two laboratories used the same testing methods, seven different testing strategies were applied and there was considerable variation in eligibility criteria. The implications of these variations are considered, and recommendations for the development of a consistent service for testing of somatic tissue offered.     

Predictive and pre-natal testing for Huntington Disease in Australia: results and challenges encountered during a 10-year period (1994-2003)

This study summarizes 10-years' experience of predictive and pre-natal testing and pre-implantation genetic diagnosis (PGD) for Huntington disease (HD) in Australia. Results are presented from 2036 direct mutation predictive tests conducted between January 1994 and December 2003. Thirty-eight per cent of results (776/2036) were positive, 56% (1140/2036) were negative, and 6% (120/2036)) were in the mutable normal (27-35 CAG repeats) or in the reduced penetrance (36-39 CAG repeats) ranges. Ninety-four per cent (1908/2036) and 6% (128/2036) of those tested had prior genetic risks of 50% and 25%, respectively. Twenty-seven per cent (34/128) of those at 25% risk had their genetic status changed to positive, thus revealing the positive status of their at-risk parent. During this period, 63 pre-natal tests were also conducted, and 13 children were born following PGD for HD. Social workers specializing in predictive testing counselling over this 10-year period across Australia identified and summarized particularly challenging counselling issues. These included the interpretation of mutable normal and reduced penetrance range test results, potential conflicts of interest between family members regarding testing decisions, unanticipated consequences of both predictive and pre-natal testing decisions, the importance of following protocols for predictive testing to facilitate long-term adjustment to results, and the potential for genetic discrimination. The identified issues highlight the importance of the protocols for predictive testing and indicate that extension of the international guidelines published in 1994 may be timely.     

Offering prenatal diagnostic tests: European guidelines for clinical practice

For over four decades, it has been possible to offer prenatal diagnostic testing for fetal abnormalities. Prenatal testing is now available for a wide range of monogenic disorders as well as chromosomal abnormalities and should be provided within the ethical framework of informed consent and autonomous choice. However, there are no published guidelines for health professionals from varied disciplines who offer prenatal diagnosis (PND) in a range of possible settings including departments of maternity, obstetrics and clinical genetics. We used an Expert Group technique to develop a set of guidelines for provision of prenatal diagnostic services. Thirteen European health professionals, all experts in PND, participated in a workshop to develop the guidelines, which were then subjected to a wide consultation process. The objective of PND was defined as providing prenatal diagnostic testing services (for genetic conditions) that enable families to make informed choices consistent with their individual needs and values and which support them in dealing with the outcome of such testing. General principles, logistical considerations, clinical care and counselling topics are all described and are equally applicable to invasive and non-invasive testing. These guidelines provide a framework for ethical clinical care; however, they are flexible enough to enable practitioners to adapt them to their particular setting. Ideally, an individualised approach to each family is required to ensure autonomous choice and informed consent regarding prenatal diagnostic testing within the local ethical and legal framework.     

Cancer worries, risk perceptions and associations with interest in DNA testing and clinic satisfaction in a familial colorectal cancer clinic

Multi-disciplinary familial cancer clinics are becoming an integral part of cancer services. It is, therefore, important to assess how attendance at these clinics impacts on cancer-related concerns, risk perceptions and behavioural intentions, and how the clinic services are being received by those using them. This study has assessed a familial colorectal cancer clinic with respect to cancer-related worries and risk perceptions and their impact on interest in DNA testing and overall satisfaction with the clinic. Pre- and post-clinic questionnaires were completed by 127 patients and relatives attending the clinic. After attending the clinic, the proportion of people 'very' or 'extremely' worried about developing bowel cancer reduced from 49 (pre-clinic) to 34% (p = 0.002). Worry about bowel cancer was positively associated with younger age, higher education level and higher perceived risk of developing cancer. A reduction in level of risk perception correlated with a lower likelihood of feeling 'very worried' about developing bowel cancer. Of those intending to go ahead with DNA testing, 58% were 'very worried' about bowel cancer compared with 15% of those not intending to proceed with testing, suggesting that worry was a motivation for interest in DNA testing. One-third of participants indicated another session of genetic counselling would be helpful. Within this group, a higher proportion was very worried about bowel cancer (43%) than for those who did not want another session (17%). Attendance at this familial colorectal cancer clinic alleviated worry for many individuals, partly due to improved information about risk of colorectal cancer.     

Interest in genetic testing among first-degree relatives of breast cancer patients

The recent cloning of a breast-ovarian cancer susceptibility gene (BRCA1), and determination of the locus of a related gene (BRCA2), offers potential for clinical genetic testing for breast cancer susceptibility. This study examined interest in and expectations about an impending genetic test among first-degree relatives (FDRs) of breast cancer patients. One hundred five females completed two structured telephone interviews to assess demographics, breast cancer risk factors, psychological factors, and attitudes about genetic testing for breast cancer susceptibility. Overall, 91% of FDRs said that they would want to be tested, 4% said they would not, and 5% were uncertain. The most commonly cited reasons for wanting genetic testing were to learn about one's children's risk, to increase use of cancer screening tests, and to take better care of oneself. Women with less formal education were motivated by childbearing decisions and future planning to a greater degree than were women with education beyond high school. Most women anticipated a negative psychological impact of positive test results, involving increased anxiety (83%), depression (80%), and impaired quality of life (46%). In addition, 72% of women indicated that they would still worry if they tested negative. In multivariate regression analysis, level of baseline depression was the strongest predictor of an anticipated negative impact of genetic testing (Beta =.15; P,.0001). These results suggest that the demand for genetic testing for breast cancer susceptibility may be great, even among women who are not likely to have predisposing mutations. Prior to widespread availability of such testing, it will be critical to develop informed consent protocols to educate individuals about the benefits and limitations of predictive testing for this multifactorial disease. © 1995 Wiley-Liss, Inc.     

Identifying mental health services in clinical genetic settings

The purpose of this study was to examine the mental health needs of individuals at risk for adult onset hereditary disorder (AOHD) from the perspective of their genetic service providers, as it is unknown to what extent psychosocial services are required and being met. A mail-out survey was sent to 281 providers on the membership lists of the Canadian Association of Genetic Counsellors and the Canadian College of Medical Geneticists. The survey assessed psychosocial issues that were most commonly observed by geneticists, genetic counsellors (GCs), and nurses as well as availability and types of psychosocial services offered. Of the 129 respondents, half of genetic service providers reported observing signs of depression and anxiety, while 44% noted patients' concerns regarding relationships with family and friends. In terms of providing counselling to patients, as the level of psychological risk increased, confidence in dealing with these issues decreased. In addition, significantly more GCs reported that further training in psychosocial issues would be most beneficial to them if resources were available. As a feature of patient care, it is recommended that gene-based predictive testing include an integrative model of psychosocial services as well as training for genetic service providers in specific areas of AOHD mental health.     

An European overview of genetic counselling supervision provision

Genetic testing is becoming more commonplace in general and specialist health care, and should always be accompanied by genetic counselling, according to legislation in many European countries and recommendations by professional bodies.Personal and professional competence is necessary to provide safe and effective genetic counselling. Clinical and counselling supervision of genetics healthcare practitioners plays a key role in quality assurance, providing a safe environment not only for patients but for professionals too. However, in many European countries, genetic counsellors are still an emerging professional group and counselling supervision is not routinely offered and there are no enough evidences on the impact of these insufficiencies. This study aimed to explore the current status of genetic counselling supervision provision across Europe and to ascertain factors that might be relevant for the successful implementation of counselling supervision.A total of 100 practitioners responded to an online survey; respondents were from 18 countries, with the majority working in France (27%) and Spain (17%). Only 34 participants reported having access to genetic counselling supervision. Country of origin, the existence of a regulation system and years of experience were factors identified as relevant, influencing access and characteristics of counselling supervision.Although there is a growing number of genetic counsellors trained at European level, just a few countries have implemented and required as mandatory the access to genetic counselling supervision. Nevertheless, this is essential to ensure a safe and effective genetic counselling and should be regulated at the European genetic healthcare services.     

An evaluation of needs of female BRCA1 and BRCA2 carriers undergoing genetic counselling

BACKGROUND—The discovery of the breast and ovarian cancer susceptibility genes BRCA1 and BRCA2 has improved our ability to counsel women at increased risk of developing breast and ovarian cancer. The objective of our study was to identify the needs of women who have undergone genetic counselling and testing for BRCA1/2 and to determine the impact of receiving a positive BRCA1/2 result. This is the first study to report on a large group of women who have received positive BRCA1/2 mutation results.
METHODS—Questionnaires were distributed to 105 women who had received pre- and post-test genetic counselling for a positive BRCA1/2 result at the University of Toronto or at McGill University in Montreal, Canada between the years of 1994 and 1998. The questionnaire items included patient motivation for seeking genetic services, information needs, screening and prophylactic surgery practices, satisfaction with access to services and support, the desire for a support group, and overall client satisfaction.
RESULTS—Seventy nine female carriers were surveyed. The majority of the respondents (77%) were satisfied with the information they received during the genetic counselling process. Women with a previous diagnosis of cancer indicated that they needed more information relating to cancer treatment compared to women without cancer (p=0.05). Nineteen percent of the women felt they needed more support than was received. Fifty eight percent of the women reported that their screening practices had changed since they received their result. Young women (below the age of 50) and women with no previous diagnosis of cancer were most likely to have changed their screening practices. Nearly two thirds of the respondents said they had considered prophylactic surgery of the breasts or ovaries. Twenty eight percent of the women had prophylactic mastectomy and 54% had undergone prophylactic oophorectomy. Women with an educational level of high school or more were more likely to have undergone prophylactic bilateral mastectomy than those with less education (p=0.07) but were less likely to undergo prophylactic oophorectomy (p=0.0007).
CONCLUSION—These findings have a direct impact on the counselling and risk management of female BRCA mutation carriers. Age, education, and a previous diagnosis of cancer are important determinants in a woman's decision making after receiving positive genetic test results.

Psychosocial care in family cancer clinics in The Netherlands: a brief report

The present survey was undertaken to obtain a better understanding of the organisation of standard psychosocial services at the family cancer clinics in The Netherlands. Colleagues at the nine family cancer clinics in The Netherlands completed a brief questionnaire. It was found that all clinics offered professional psychosocial support for asymptomatic women from hereditary breast-ovarian cancer (HBOC) families. On average, one half-time psychosocial worker (usually a social worker and/or a psychologist) was involved in the genetic counselling. All clinics have developed education material about HBOC independently. As a result of the survey, an effort is made to coordinate the development of education material. Furthermore, it is concluded that more attention should be paid to symptomatic mutation carriers and those individuals, who receive inconclusive genetic test results. These subgroups are usually excluded from the protocols for psychosocial care in genetic counselling.     

What is ideal genetic counselling? A survey of current international guidelines

The objective of this article is to review guidelines that address counselling in the context of genetic testing in order to summarise what aspects of counselling they consider most important, and to examine how they construct the ideal of genetic counselling. Guidelines were collected by examining the websites of different international professional, political, ethical and patient organisations, either previously known or found with the help of the Google search engine, and also using references listed in other studies. The most frequently mentioned topics in the collected 56 guidelines were sought, and this was carried out with the software package Qualitative Solutions and Research for Non-numerical Unstructured Data Indexing Searching and Theorizing. Topics related to genetic counselling that were mentioned in at least 30 of 56 collected documents were considered to be the most important aspects of genetic counselling. The ideal of genetic counselling is expressed in the analysed guidelines as being composed of (1) an appropriately trained professional who understands genetics and its ethical implications well; (2) relevant and objective information; (3) assurance of the counsellee's understanding; (4) psychological support; (5) informed consent; (6) confidentiality of genetic information; (7) considering familial implications; (8) appropriate handling of potential discrimination of testing; and (9) assuring autonomous decision-making by the counsellee. The ideal of genetic counselling is rather consistent in the guidelines, but there are some contradictions between the requirements of objective information-giving and adapting counselling to counsellee's circumstances.     

Statement of the ESHG on direct-to-consumer genetic testing for health-related purposes

Many private companies offer direct-to-consumer (DTC) genetic testing services. Some tests may detect severe and highly penetrant monogenic disorders, while other tests are for genetic variants found associated with increased susceptibility for common and complex diseases in large-scale population studies. Through its Public and Professional Policy committee followed by member and expert consultation, the European Society of Human Genetics has developed the following policy on advertising and provision of predictive genetic tests by such DTC companies: (1) clinical utility of a genetic test shall be an essential criterion for deciding to offer this test to a person or a group of persons; (2) laboratories providing genetic tests should comply with accepted quality standards, including those regarding laboratory personnel qualifications; (3) information about the purpose and appropriateness of testing should be given before the test is done; (4) genetic counselling appropriate to the type of test and disease should be offered; and for some tests psychosocial evaluation and follow-up should be available; (5) privacy and confidentiality of sensitive genetic information should be secured and the data safely guarded; (6) special measures should be taken to avoid inappropriate testing of minors and other legally incapacitated persons; (7) all claims regarding genetic tests should be transparent; advertisement should be unbiased and marketing of genetic tests should be fair; (8) in biomedical research, health care and marketing, respect should be given to relevant ethical principles, as well as international treaties and recommendations regarding genetic testing; and (9) nationally approved guidelines considering all the above-mentioned aspects should be made and followed.Progress in biotechnology and genetic research has led to an increasing number of tests with potential predictive health information. In parallel with this development, private companies have established direct-to-consumer (DTC) genetic testing services, both for monogenic and severe genetic disorders and for genetic variants possibly associated with common complex diseases (susceptibility variants). Tests are also offered for conditions of minor or no health importance.The European Society of Human Genetics (ESHG) is concerned about the way in which commercial companies are currently introducing genetic tests into the market outside of the scope of the traditional healthcare system. With this Statement, we provide a formal policy with regard to DTC advertising and provision of genetic tests with predictive health information. Important issues, such as DTC paternity and ancestry testing, are thus outside the scope of this Statement.In line with the Council of Europe''s Additional Protocol to the Convention on Human Rights and Biomedicine, concerning Genetic Testing for Health Purposes and the OECD Guidelines for Quality Assurance in Molecular Genetic Testing, this Statement highlights the importance of right to information, quality of the test performed, clinical usefulness of the tests provided, the need for individualized medical supervision, the provision of pre-test information and genetic counselling, follow-up and support in the interpretation of results and their psychosocial impact, the protection of persons not able to consent, respect for privacy and confidentiality, and the storing of the samples, their property and respect for ethical principles in research.     

Disclosure of insurability risks in research and clinical consent forms

Genetic testing results and research findings raise concerns about access to genetic information by insurers. Recently, the Canadian Life and Health Insurance Association reaffirmed its prerogative to request, for underwriting purposes, the disclosure of clinical and research genetic test results if the participant/patient or his physician has knowledge of the results. Studies have shown that access to genetic information to determine insurability can, in limited instances, lead to actual, or fear of, genetic discrimination, result in individuals refusing to undergo testing or declining participation in genomic research, and being asked to pay higher premiums or denied access to certain types of insurance. Obtaining informed consent for genetic testing and genomic research is crucial and should take into account the potential need to disclose possible insurability risks to patients and participants. Our study analyzed clinical and research consent forms, templates and guidelines from Quebec to investigate two questions: (1) whether consent forms include clauses providing information on potential insurability risks and (2) when such potential risks are included, what information is provided and how it is formulated. Our findings show that current information on insurability risks in Quebec’s forms/guidelines lack coherence, potentially resulting in patients/participants receiving inconsistent information.     

Genetic counselling protocols for hereditary non-polyposis colorectal cancer: a survey of UK regional genetics centres

Predictive testing for hereditary non-polyposis colorectal cancer (HNPCC) is typically offered within an extended genetic counselling protocol, originally developed in the context of Huntington's Disease. We conducted a questionnaire survey of 20 UK regional genetics centres to obtain evidence regarding current approaches to HNPCC pre-test counselling. Centres were asked to describe the structure and content of pre-test counselling and their views on shortening the protocol. Sixteen centres responded to the survey. Four centres were considering shortening the protocol or had already done so. The remaining centres followed an extended protocol of two sessions separated by a 1-month period for reflection, although two centres conceded that the protocol had been reduced in certain cases. Different centres used different terminology to describe the content of pre-test counselling. Although content areas relating to education or impact of test results were covered more frequently than those relating to reflection, there was a marked tendency to consider all three areas as essential and to use both educational and reflective counselling, even in those centres that favoured a shortened protocol. This apparent dilemma highlights both the practical difficulty of how to shorten HNPCC pre-test counselling protocols and the need for controlled trials of different approaches.     

Use of record linkage between a statewide genetics service and a birth defects/congenital malformations register to determine use of genetic counselling services

The Birth Defects/Congenital Malformations Register of the Victorian Department of Human Services contains detailed, confidential information on over 2,000 babies born with a birth defect each year in Victoria, Australia, representing approximately 3% of the annual number of births. For 1991 and 1993, the type of anomaly was categorised as warranting a high, moderate, or low need of referral for genetic counselling, depending on risk of recurrence and possible genetic cause. The Victorian Clinical Genetics Service at the Murdoch Institute, Melbourne, offers free, centralised genetic counselling services for the entire state. A comparison of case records between the two agencies has shown little difference in overall use of genetic counselling between 1991 (17%) and 1993 (16%). Rate of uptake in the “high need” category improved only slightly during that period, from 40% in 1991 to 43% in 1993. Utilization of genetic counselling services did not vary disproportionately with mother's country of birth, but was higher for older mothers. As was expected, rates were highest when a baby was born at the only hospital that provides on-site genetic counselling services. Even where a statewide genetic counselling service is in place, it is disappointing that over half of those judged at high need for genetic counselling are not making use of this service. This study will provide baseline information to which future studies can be compared. Using the same study methodology, it will be possible to examine whether the uptake rate increases in accordance with increased genetic services. Am. J. Med.
