This study was undertaken to examine transmission of information to first-degree relatives of BRCA1 mutation carriers and uptake of genetic testing. The intention was to consider revision of current legislation related to privacy if information on life-saving health care was not disseminated to at-risk family members. The Norwegian Radium Hospital provides clinical genetics services for families at high risk for hereditary breast and ovarian cancer. Together with major hospitals nationwide we provide medical surveillance. Nearly all expenses are covered by the National Health insurance. Because of the high number of families with founder mutations in BRCA1, we are in a unique position to gather information about these groups. Within a consecutive series, we identified 75 BRCA1 mutation carriers and registered information transmission and uptake of genetic testing 6 months or more after the index mutation carriers had been informed about their mutation status. These 75 BRCA1 mutation carriers had 172 living first-degree relatives, aged 18 years or older (84 females, 88 males). Forty-four out of 54 (81.5%) of females over 30 had opted for genetic testing. The testing rate among all relatives was 43%. At any age, 63% of the females underwent genetic testing compared with 24% of the males (p<0.05). The overwhelming majority of adult females at risk opted for genetic testing. Males with daughters more frequently than males without daughters asked for testing. The findings give neither reason to reconsider legislation on privacy, nor for us to consider more aggressive methods of contacting relatives. 相似文献

Women with a strong family history of breast and/or ovarian cancer can now have genetic testing, that may identify mutations associated with increased cancer predisposition. Within the context of a clinical trial evaluating printed educational materials, we examined motivation, satisfaction, coping, and perceptions of genetic counseling and testing among 159 women who underwent pretest counseling and made a testing decision. Ninety-six percent of the participants elected to have BRCA1/2 testing. When making a decision about genetic testing, study participants were concerned less about the potential negative effects that could result from testing than the potential benefits. After counseling, participants said that they felt better able to make decisions that were right for them and that their questions and concerns were adequately addressed during the session. Ninety-five percent of the women were satisfied with their test decision. Participants used a range of strategies to cope with thoughts and feelings about cancer and/or genetic testing immediately following test decision. Results suggest that the genetic counseling session helped women make decisions about testing for BRCA1 and BRCA2, even in the setting of a trial in which all women also received detailed educational materials. Further, the results indicate that future research focusing on perceptions of risks and benefits of testing and of coping strategies immediately following test decision may be warranted. 相似文献

Objective:
To develop and evaluate a decision aid designed to prepare patients of advanced maternal age for counseling about prenatal diagnostic testing.
Setting:
A regional genetics center.
Design:
A before/after study.
Interventions:
Participants used an audioguided workbook to learn about options and outcomes and to clarify personal risks, values, questions, and predispositions.
Subjects:
21 women of advanced maternal age and 17 spouses.
Main outcome measures:
Knowledge of prenatal testing alternatives, decisional conflict, level of anxiety, and acceptability of the decision aid.
Results:
After using the decision aid, participants had significantly reduced decisional conflict (uncertainty) and a significant increase in knowledge. There was no effect on state or trait anxiety. More than three-quarters of participants were satisfied with the length, clarity, balance, and acceptability of the decision aid.
Conclusions:
The decision aid shows promise as a useful aid for preparing couples for counseling. 相似文献

This article discusses the genetic counseling protocols which were developed and counseling issues that have arisen in the first 2 years of evaluating a large kindred with a BRCA1 mutation. The rationale for the development of the genetic counseling protocols and specific genetic counseling visual aids are presented and discussed. The protocols and counseling aids can serve as models for other programs offering cancer susceptibility testing. The observations of study counselors about study subject concerns and responses to genetic testing at the time of the pretest and posttest counseling sessions are presented. 相似文献

This repeated measures study examines (1) the change in subjective risk of mutations pre- to postcounseling, (2) the accuracy of BRCAPRO estimates of mutations, and (3) the discrepancy between subjective risk and BRCAPRO estimates of mutations before and after genetic counseling. Ninety-nine Ashkenazi Jewish individuals pursued testing for BRCA1/2 mutations. Most had a personal cancer history (N = 51; family only: N = 48); and received uninformative negative results (N = 66; positives: N = 23; informative negative: N = 10). The coping strategy of defensive pessimism predicts that individuals will believe the worst case scenario to better cope with a potential negative outcome. Consistent with this, most felt they would have a mutation, if not mutations in both genes. The BRCAPRO model appeared to overestimate risk of having a mutation in this sample (p < .001). BRCAPRO overestimates notwithstanding, genetic counseling increased accuracy of subjective risk (p < .01). Individuals with a family-only cancer history had the least accurate estimates of risk (p < .05) and may need further intervention to either manage anxiety or improve knowledge. 相似文献

We present three vignettes based on participants counseled as part of a clinical research program. These include a young unaffected woman at risk for a familial mutation, a newly diagnosed breast cancer patient, and a woman with recurrent ovarian cancer. Through the use of detailed vignettes, multifaceted issues that arise in cancer genetic counseling are highlighted. 相似文献

BRCA+ breast cancer patients face high risk for a second breast cancer and ovarian cancer. Helping these women decide among risk-reducing options requires effectively conveying complex, emotionally-laden, information. To support their decision-making needs, we developed a web-based decision aid (DA) as an adjunct to genetic counseling. Phase 1 used focus groups to determine decision-making needs. These findings and the Ottawa Decision Support Framework guided the DA development. Phase 2 involved nine focus groups of four stakeholder types (BRCA+ breast cancer patients, breast cancer advocates, and genetics and oncology professionals) to evaluate the DA's decision-making utility, information content, visual display, and implementation. Overall, feedback was very favorable about the DA, especially a values and preferences ranking-exercise and an output page displaying personalized responses. Stakeholders were divided as to whether the DA should be offered at-home versus only in a clinical setting. This well-received DA will be further tested to determine accessibility and effectiveness. 相似文献

Little is known about the impact of cancer genetic counseling and testing on health behaviors in racial and ethnic subgroups. This prospective observational study examined use of risk reduction strategies following BRCA1 counseling and testing. Participants were female members of an African American kindred who received genetic education, counseling and testing (n = 40) and completed a 1-year follow-up interview. Mutation carriers were more likely to opt for breast (100%, 7/7) and ovarian (25%; 1 of 4) cancer surveillance than prophylactic surgery. Following genetic counseling, 71% (5/7) of the BRCA1 carriers who opted for surveillance reported having a mammogram within the year following receipt of their genetic test results. Ovarian cancer screening among mutation carriers increased from 0% at baseline to 25% (one of four) at 1 year. Compared to noncarriers (23%, 7/30), carriers (70%, 7/10) were more likely to discuss their BRCA1 test results with their primary health care providers. Surveillance for breast cancer was preferred to prophylactic surgery and chemoprevention as a way to reduce risk for these cancers. Our data indicate that patient-provider communication about BRCA1 test results is suboptimal. 相似文献

Genetic testing for inherited cancer susceptibility, based on the recently identified. BRCA1 and BRCA2 genes, will soon be available on a large scale. However, at present, genetic test results do not lead to clearly indicated diagnostic or preventive measures, and the nature of the psychological impact of BRCA1/2 testing is still largely unknown. This uncertainty, combined with preliminary evidence suggesting significant individual differences in reactions to genetic susceptibility feedback, constitutes a unique challenge for any individual contemplating such testing. We outline the nature of this challenge and then propose an intervention strategy designed to help individuals make deeply processed and psychologically well-informed decisions with regard to their genetic susceptibility. The intervention is guided by recent research findings and theory on the cognitive–emotional processing of cancer-risk information. Specifically, the goal is to prepare the individual for genetic testing by (1) cognitively and emotionally activating, or preliving, the individual's potential reactions to testing feedback; (2) facilitating accurate appraisal of the individual's cognitive–emotional reactions; and (3) enabling the individual to process these reactions through the use of well-established clinical techniques. 相似文献

Women with a germline pathogenic variant in the BReast CAncer susceptibility genes (BRCA1 or BRCA2) have an increased risk of early-onset breast and ovarian cancer. In addition to weighing cancer screening and risk-reduction options, healthy BRCA mutation carriers of childbearing age may choose to preclude passing the mutation to the next generation. In the current study, we report on preimplantation genetic diagnosis (PGD) practices in BRCA-positive Israeli women who were offered PGD at no cost. Methods: we measured PGD uptake, decision satisfaction or regret, and predictors of uptake. Of the 70 participant female carriers, only 25.7% chose to use PGD to prevent transmission of the mutation, and were not predicted by age or religious affiliation. For those who chose IVF/PGD, satisfaction with the decision regarding IVF and PGD was significantly higher than those who did not have IVF and PGD (p?<?0.04). Experiencing previous infertility was the only significant predictor of uptake of IVF/PGD (p?<?0.001), which may suggest that BRCA status is secondary to infertility in the decision-making process for PGD in women with a BRCA mutation. 相似文献

The cloning of BRCA1, a susceptibility gene for inherited breast cancer, has made genetic screening possible for individuals and families whose medical histories are suggestive of an inherited predisposition to breast cancer. To date, few systematic attempts have been made to determine the level of knowledge about breast cancer genetics among women who are likely to seek BRCA1 screening when it becomes widely available. The present study attempted to assess the general knowledge about BRCA1 mutations in two groups: (1) first-degree relatives (FDRs) of breast cancer patients; and (2) women with a previous diagnosis of breast cancer. A self-administered, thirty-item questionnaire was developed through a pilot study. Ten of the items were objective, factual questions about breast cancer genetics. Responses to these questions were used to generate an overall knowledge score for each respondent. The study population was moderately knowledgeable about breast cancer genetics, with an average score of 5.35 out of 10. Counselors should not underestimate the importance of evaluating each counselee's existing knowledge about breast cancer, which can affect the provision and reception of genetic information. In particular, specific areas of knowledge that may be confusing or misunderstood were identified and these topics are discussed in detail. 相似文献

The literature on risk perception in women from high-risk breast cancer families reveals persistent over-estimation of risk, even after counseling. In this study, a communication aid was designed to facilitate discussion of risk between clinical geneticists and genetic counselors and women from this high-risk population. Method: Stage 1. The aid was developed by an expert panel of clinical geneticists, genetic counselors, psychologists, an epidemiologist, an oncologist, linguists and a consumer. It was guided by the international literature on risk communication and a large multi-centre Australian study of risk communication. The 13 page full-color communication aid used varying formats of words, numbers, graphs and pie-charts to address (a) the woman’s subjective risk; (b) the population risk of breast cancer; c) the risk of inherited breast cancer; (d) the cumulative risk for women with BRCA1 and BRCA2 mutations; (e) family risk factors; (f) the woman’s suitability for genetic testing; (h) screening and management recommendations, and (i) a re-assessment of the woman’s subjective risk. Stage 2: A before–after pilot study of 38 women who were unaffected with breast cancer and were attending four Australian familial cancer clinics was undertaken. Baseline and follow-up questionnaires were completed by 27 women. Outcomes were compared to those observed in 107 similar women undergoing genetic counseling without the communication aid in 2001. Results: The risk communication aid appears to be beneficial; breast cancer genetics knowledge improved in some areas and importantly, risk perceptions improved in the cohort receiving the communication aid. Psychological measures showed no difference in anxiety or depression between the group receiving the communication aid and the comparison cohort. Women and clinicians were very positive about the usefulness of the communication aid as an adjunct to the genetic counseling consultation. 相似文献

In familial breast/ovarian cancer, the information that the proband is able to supply about other family members is of critical importance for genetic counseling. This frequently requires family communication. Forty-six women attending a cancer genetics clinic were interviewed as part of a longitudinal study. Nearly all reported affected maternal, rather than paternal relatives, which may indicate lack of awareness by women with paternal histories. There was also much more communication among female relatives. Mothers, where they were still alive, were key figures in supplying family information. Although the majority of the sample contacted at least one relative regarding counseling, most named a relative with whom they did not feel able to communicate on this subject. Probands balanced the perceived obligation of passing on information with that of not causing alarm. Communication, both obtaining and giving information, was impeded by adoption, divorce and remarriage, family rifts, and large age gaps between siblings. 相似文献

This qualitative study asked Australian Genetic Counselors and Clinical Geneticists working in cancer genetics to describe their practice when a woman attends a consultation about her family history and her risk of developing breast cancer. Twenty-nine out of 36 Clinical Geneticists/Genetic Counselors returned the questionnaire (82%). Participants identified the key goals of the consultation as (a) identifying the individual needs and concerns of the woman, (b) providing information on genes and chromosomes, (c) giving an individual risk assessment in the context of supportive interaction, and (d) discussing the pros and cons of genetic testing and putting a surveillance plan into place. Respondents emphasized the dual importance of counseling/support and information provision in this setting, suggesting that one could not be given without the other. Implications for clinical practice are discussed. 相似文献

Based on the cognitive-social health information processing model, we identified cognitive profiles of women at risk for breast and ovarian cancer. Prior to genetic counselling, participants (N?=?171) completed a study questionnaire concerning their cognitive and affective responses to being at genetic risk. Using cluster analysis, four cognitive profiles were generated: (a) high perceived risk/low coping; (b) low value of screening/high expectancy of cancer; (c) moderate perceived risk/moderate efficacy of prevention/low informativeness of test result; and (d) high efficacy of prevention/high coping. The majority of women in Clusters One, Two and Three had no personal history of cancer, whereas Cluster Four consisted almost entirely of women affected with cancer. Women in Cluster One had the highest number of affected relatives and experienced higher levels of distress than women in the other three clusters. These results highlight the need to consider the psychological profile of women undergoing genetic testing when designing counselling interventions and messages. 相似文献

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

High levels of cancer specific distress have been found before and after genetic counseling for breast cancer. This study investigated the process of reducing distress during 111 genetic counseling consultations for familial breast cancer. Consultations were audiotaped, transcribed, and a detailed coding system developed to measure cues of emotional distress from the patient, and consultant (clinical geneticist or genetic counselor) behaviors before and after the cues. At least 1 emotional cue was given in 64 consultations, with a median of 1 cue per consultation. More emotional cues of distress occurred when the consultant responded empathetically to the first cue of distress. Satisfaction outcomes were largely positive regardless of the consultant's attentiveness to distress. Postconsultation depression scores were significantly reduced if more empathic responses were given, but anxiety remained the same. These results are discussed and recommendations are made for improving patient care. 相似文献
