RESUMO

BACKGROUND: The recent identification of several BRCA1/BRCA2 founder mutations among Ashkenazi Jewish individuals has led to increased salience of BRCA1/BRCA2 testing for Jewish individuals. Little is known about interest in BRCA1/BRCA2 testing among Ashkenazi Jews from the general population. Furthermore, previous research has not generally evaluated the impact of education on interest in testing among individuals from the general population. The goal of the current study was to examine whether a brief educational booklet regarding BRCA1/BRCA2 testing would influence knowledge, attitudes, and interest in testing among Ashkenazi Jewish women from the general population. METHODS: After a baseline telephone interview, participants were randomized to receive either genetic testing educational print materials (n = 195 women) or general breast cancer education control materials (n = 196 women). One month after receiving these materials, the authors reassessed knowledge, attitudes, and interest in BRCA1/BRCA2 gene testing. RESULTS: Relative to the breast cancer education control materials, the genetic testing education materials led to increased knowledge, increased perception of the risks and limitations of testing, and decreased interest in obtaining a BRCA1/BRCA2 mutation test. CONCLUSIONS: These data indicate that preliminary print education can be used to educate low-risk individuals about BRCA1/BRCA2 genetic testing. This approach may be used to educate low-risk individuals about the benefits and risks/limitations of BRCA1/BRCA2 testing, so that they can make informed decisions about whether to pursue genetic counseling.

RESUMO

The use of anonymized stored tissue is a routine practice in genetic research. Investigators who utilize stored samples are neither required nor able to obtain informed consent before each use. Many genetic studies, however, are conducted on specific ethnic populations (e.g., Ashkenazi Jews). The results in these cases, although individually anonymous, are not anonymous with respect to the ethnicity of the participants. This lack of group anonymity has led to concern about the possibility of stigmatization and discrimination based on the results of the genetic research. In the present study we surveyed Jewish individuals about their attitudes regarding the practice of using stored DNA samples for genetic research. Specifically, we were interested in whether attitudes about informed consent and willingness to participate in genetics research using stored DNA would depend on the circumstances in which the material was collected (i.e., clinical setting vs. research setting) and the characteristics of the disease or trait under investigation. Overall, most respondents reported that written informed consent should be required and that they would be willing to provide such consent. Participants were most willing to provide consent, however, when the sample had been collected in a research rather than clinical setting. Further, participants were more likely to endorse the need for obtaining consent when the sample was collected in a clinical setting. Finally, participants were significantly less willing to participate in research that examined stereotypical or potentially stigmatizing traits as opposed to research that examined medical or mental illnesses.

RESUMO

To date, research examining adherence to genetic counseling principles has focused on specific counseling activities such as the giving or withholding of information and responding to client requests for advice. We audiotaped 43 prenatal genetic counseling sessions and used data-driven, qualitative, sociolinguistic methodologies to investigate how language choices facilitate or hinder the counseling process. Transcripts of each session were prepared for sociolinguistic analysis of the emergent discourse that included studying conversational style, speaker-listener symmetry, directness, and other interactional patterns. Analysis of our data demonstrates that: 1) indirect speech, marked by the use of hints, hedges, and other politeness strategies, facilitates rapport and mitigates the tension between a client-centered relationship and a counselor-driven agenda; 2) direct speech, or speaking literally, is an effective strategy for providing information and education; and 3) confusion exists between the use of indirect speech and the intent to provide nondirective counseling, especially when facilitating client decision-making. Indirect responses to client questions, such as those that include the phrases "some people" or "most people," helped to maintain counselor neutrality; however, this well-intended indirectness, used to preserve client autonomy, may have obstructed direct explorations of client needs. We argue that the genetic counseling process requires increased flexibility in the use of direct and indirect speech and provide new insights into how "talk" affects the work of genetic counselors.

RESUMO

PURPOSE: To determine the genetics education needs and priorities of dietitians, occupational therapists, physical therapists, psychologists, speech-language-hearing specialists, and social workers. METHODS: A random sample mail survey of 3,600 members of 6 national health professional organizations was undertaken in 1998 and resulted in 1,958 responses. RESULTS: A majority worked with clients with genetic conditions, most were providing genetic services to some clients, few had high confidence in providing genetic services, most had little or no education in genetics, and two-thirds wanted continuing education. CONCLUSION: The study shows a critical need for genetics education of allied and counseling health professionals.

RESUMO

BACKGROUND: Little is known about the perception of bilateral prophylactic mastectomy (BPM), and whether perceptions are influenced by a family history of breast cancer. It is also unclear what factors may play a role in selecting BPM for follow-up care. METHODS: Samples of predominantly Caucasian, well-educated women with (n = 129) and without (n = 104) family histories of breast cancer were provided a vignette of a woman at increased risk. They selected one of two follow-up options: (1) clinical breast examination, breast self exam, and annual mammography or (2) BPM. RESULTS: The samples did not differ on the decision to select BPM (29.5% vs 22.1%). The family history sample reported worry about breast cancer as a problem (34.4%) more often than women with no history (15.7%). Multivariate analysis found worry and estimated 10-year risk of the woman in the vignette as significant predictors of selecting BPM. CONCLUSIONS: Approximately 25% of our sample selected BPM as the preferred option. The majority supported the need to discuss BPM among women at increased risk. Finally, both factors associated with the selection of BPM (worry, risk assessment) are potentially amenable to psychosocial or educational approaches. There is a clear need for assessment of worry and risk perception prior to surgical decision making.

RESUMO

OBJECTIVES: We conducted a randomized trial to investigate racial differences in response to two alternate pretest education strategies for BRCA1 genetic testing: a standard education model and an education plus counseling (E + C) model. MATERIALS AND METHODS: Two hundred twenty-eight Caucasian women and 70 African American women with a family history of breast or ovarian cancer were contacted for a baseline telephone interview to assess sociodemographic characteristics, number of relatives affected with cancer, and race before pretest education. Outcome variables included changes from baseline to 1-month follow-up in cancer-related distress and genetic testing intentions, as well as provision of a blood sample after the education session. RESULTS: African American women were found to differ significantly from Caucasian women in the effects of the interventions on testing intentions and provision of a blood sample. Specifically, in African American women, E + C led to greater increases than education only in intentions to be tested and provision of a blood sample. These effects were independent of socioeconomic status and referral mechanisms. In Caucasian women, there were no differential effects of the interventions on these outcomes. Reductions in cancer-specific distress were evidenced in all study groups. However, this decrease, although not significantly different, was smallest among African American women who received E + C. CONCLUSIONS: In low- to moderate-risk African American women, pretest education and counseling may motivate BRCA1 testing. Further research is needed to explore the mechanisms of impact of the alternate pretest education strategies and to increase the cultural sensitivity of education and counseling protocols.

RESUMO

Informed consent for BRCA1 mutation testing will require adequate knowledge of patterns of inheritance of cancer and the benefits, limitations, and risks of DNA testing. This study examined knowledge about the inheritance of breast cancer and attitudes about genetic testing for breast-ovarian cancer susceptibility in women at increased risk. Knowledge and attitudes were measured in 407 African American and Caucasian women aged 18-75 who had at least one first-degree relative (FDR) with breast and/or ovarian cancer. The average knowledge score was 6.0 out of a total of 11 (S.D. = 2.15). Compared to Caucasian women, African American women had lower levels of knowledge and had more positive attitudes about the benefits of genetic testing. There were no significant ethnic differences in attitudes about the limitations and risks of testing, however, income was negatively associated with this outcome. Ethnic differences in knowledge and attitudes about genetic testing for breast-ovarian cancer risk may be attributable to differences in exposure to genetic information and referral by health care providers.

RESUMO

BACKGROUND: In response to the isolation of the BRCA1 gene, a breast-ovarian cancer-susceptibility gene, biotechnology companies are already marketing genetic tests to health care providers and to the public. Initial studies indicate interest in BRCA1 testing in the general public and in populations at high risk. However, the optimal strategies for educating and counseling individuals have yet to be determined. PURPOSE: Our goal was to evaluate the impact of alternate strategies for pretest education and counseling on decision-making regarding BRCA1 testing among women at low to moderate risk who have a family history of breast and/or ovarian cancer. METHODS: A randomized trial design was used to evaluate the effects of education only (educational approach) and education plus counseling (counseling approach), as compared with a waiting-list (control) condition (n = 400 for all groups combined). The educational approach reviewed information about personal risk factors, inheritance of cancer susceptibility, the benefits, limitations, and risks of BRCA1 testing, and cancer screening and prevention options. The counseling approach included this information, as well as a personalized discussion of experiences with cancer in the family and the potential psychological and social impact of testing. Data on knowledge of inherited cancer and BRCA1 test characteristics, perceived risk, perceived benefits, limitations and risks of BRCA1 testing, and testing intentions were collected by use of structured telephone interviews at baseline and at 1-month follow-up. Provision of a blood sample for future testing served as a proxy measure of intention to be tested (in the education and counseling arms of the study). The effects of intervention group on study outcomes were evaluated by use of hierarchical linear regression modeling and logistic regression modeling (for the blood sample outcome). All P values are for two-sided tests. RESULTS: The educational and counseling approaches both led to significant increases in knowledge, relative to the control condition (P < .001 for both). The counseling approach, but not the educational approach, was superior to the control condition in producing significant increases in perceived limitations and risks of BRCA1 testing (P < .01) and decreases in perceived benefits (P < .05). However, neither approach produced changes in intentions to have BRCA1 testing. Prior to and following both education only and education plus counseling, approximately one half of the participants stated that they intended to be tested; after the session, 52% provided a blood sample. CONCLUSIONS: Standard educational approaches may be equally effective as expanded counseling approaches in enhancing knowledge. Since knowledge is a key aspect of medical decision-making, standard education may be adequate in situations where genetic testing must be streamlined. On the other hand, it has been argued that optimal decision-making requires not only knowledge, but also a reasoned evaluation of the positive and negative consequences of alternate decisions. Although the counseling approach is more likely to achieve this goal, it may not diminish interest in testing, even among women at low to moderate risk. Future research should focus on the merits of these alternate approaches for subgroups of individuals with different backgrounds who are being counseled in the variety of settings where BRCA1 testing is likely to be offered.

RESUMO

The identification of BRCA1 and BRCA2, two breast-ovarian cancer susceptibility genes, has brought many ethical and social issues to the forefront. This paper presents the results of a survey assessing the attitudes of 238 unaffected first-degree relatives of women with breast or ovarian cancer regarding the ethical issues of autonomy and confidentiality as they relate to BRCA1/2 testing. Baseline knowledge about BRCA1/2 and ethnic and psychosocial characteristics of our study population were examined to determine their association with women's attitudes. The majority of women (86-87%) felt that health care providers should not disclose the results of genetic tests for breast-ovarian cancer susceptibility to insurance companies or employers without written consent; however, only 56-57% felt that written consent should be required for a spouse or immediate family to receive this information. Ninety-eight percent of the women surveyed agreed that genetic testing for breast-ovarian cancer risk should be voluntary. Likewise, most women (95%) agreed that a person should be able to have genetic testing against a doctor's recommendation and 88% of the women surveyed agreed that parents should be able to consent to genetic susceptibility testing on behalf of their minor children. African American women were less concerned than Caucasian women about the protection of confidentiality in families, they were more likely to agree that an individual should still have access to testing when their physicians recommended against it, and they were more supportive of parents' rights to consent to genetic predisposition testing on behalf of their minor children. Women with coping styles characterized by higher optimism were more likely to favor access to genetic testing when a physician recommended against it, and to support parents' rights to consent to testing of their minor children. Therefore, the setting and manner in which genetic counseling and testing are delivered must be appropriately tailored to reflect these attitudinal differences and preferences.

RESUMO

BACKGROUND: DNA probes specific for whole chromosomes or portions of chromosomes can provide important information to aid the clinician in managing pregnancy and the geneticist in relaying accurate recurrence risk information to the patient. CASE: In this case, sonography was ordered because of a low fundal height in a 29-year-old primigravida at 35 weeks' gestational age; it revealed major fetal anomalies. A small supernumerary marker was seen in some cultured amniocytes. Metaphase spreads were analyzed by means of fluorescence in situ hybridization using a centromere probe specific for chromosome 22 and a whole chromosome probe for the 11 chromosome. In situ hybridization showed that the marker chromosome was a derivative of chromosome 22 with 11q material attached near the centromere. The fetal karyotype was 47,XY,+der(22) t(11;22)(q23.3;q11.2)mat. The mother was later found to be a balanced translocation carrier. CONCLUSION: It was possible to offer rapid prenatal diagnosis for this family using interphase analysis with the 22 centromere probe. The patient had chorionic villus sampling, and DNA probes were used to analyze cells directly from the biopsy. The signal representing the supernumerary marker was not observed. Karyotype analysis later showed that the fetus was normal but a translocation carrier. This report illustrates that rapid in situ hybridization can provide important information in known cases of translocation carriers.
