    ABSTRACT: Purpose:As genetic counseling and testing become more fully integrated into clinical care, alternative delivery models are increasingly prominent. This study examines predictors of genetic testing for hereditary breast/ovarian cancer among high-risk women in a randomized trial of in-person versus telephone-based genetic counseling.Methods:Methods include multivariable logistic regression and interaction analyses.Results:Of the 669 participants, 600 completed counseling and 523 received test results. As previously reported, participants randomized to telephone counseling were significantly less likely to be tested. In intention-to-treat analyses, completion of counseling and testing was associated with: race/ethnicity (odds ratio (OR) = 1.96, 95% confidence interval (CI): 1.20-3.20), perceived stress (OR = 0.89, 95% CI: 0.81-0.98), knowledge (OR = 1.12, 95% CI: 1.02-1.23), and randomization group (OR = 1.48, 95% CI: 1.01-2.16). Further, race/ethnicity moderated the association between randomization group and testing; minority women receiving telephone counseling were least likely to complete testing.Conclusion:Evidence for logistical and communication-based explanations for this interaction is presented. The overall increased access made possible with telephone genetic counseling should be considered in light of the possibility that this may also lead to lower rates of testing among high-risk minority women. Additional care should be taken to assess and address potential barriers when services are delivered by telephone.Genet Med advance online publication 18 September 2014Genetics in Medicine (2014); doi:10.1038/gim.2014.125.

    ABSTRACT: Genetic testing for breast and ovarian cancer susceptibility is now part of routine clinical practice. Although rates of risk-reducing surgery following genetic testing have been increasing, little is known about attitudes toward risk-reducing surgery in women prior to genetic counseling and testing. This study examines correlates of patient intentions to undergo risk-reducing mastectomy (RRM) and risk-reducing oophorectomy (RRO).

    ABSTRACT: As BRCA1/2 testing becomes more routine, questions remain about long-term satisfaction and quality of life following testing. Previously, we described long term distress and risk management outcomes among women with BRCA1/2 mutations. This study addresses positive psychological outcomes in BRCA1/2 carriers, describing decision satisfaction and quality of life in the years following testing METHODS: We evaluated satisfaction with testing and management decisions among 144 BRCA1/2 carriers. Prior to genetic testing, we assessed family history, sociodemographics and distress. At a mean of 5.3 years post-testing, we assessed management decisions, satisfaction with decisions and, among women with cancer, quality of life. Overall, satisfaction with decision making was high. Women who had risk reducing mastectomy or oophorectomy were more satisfied with management decisions. Participants who obtained a risk reducing oophorectomy were more satisfied with their genetic testing decision. Among affected carriers, high pretest anxiety was associated with poorer quality of life and having had risk reducing mastectomy prior to testing was associated with better quality of life. The negative impact of pre-test anxiety was diminished among women who had mastectomies before testing. BRCA1/2 carriers are satisfied with their testing and risk management decisions and report good quality of life years after testing. Having risk reducing surgery predicts increased satisfaction and improved quality of life.

    ABSTRACT: The rate of adherence to regular colonoscopy screening in individuals at increased familial risk of colorectal cancer (CRC) is suboptimal, especially among rural and other geographically underserved populations. Remote interventions may overcome geographic and system-level barriers. We compared the efficacy of a telehealth-based personalized risk assessment and communication intervention with a mailed educational brochure for improving colonoscopy screening among at-risk relatives of patients with CRC. Eligible individuals age 30 to 74 years who were not up-to-date with risk-appropriate screening and were not candidates for genetic testing were recruited after contacting patients with CRC or their next of kin in five states. Enrollees were randomly assigned as family units to either an active, personalized intervention that incorporated evidence-based risk communication and behavior change techniques, or a mailed educational brochure. The primary outcome was medically verified colonoscopy within 9 months of the intervention. Of the 481 eligible and randomly assigned at-risk relatives, 79.8% completed the outcome assessments within 9 months; 35.4% of those in the personalized intervention group and 15.7% of those in the comparison group obtained a colonoscopy. In an intent-to-treat analysis, the telehealth group was almost three times as likely to get screened as the low-intensity comparison group (odds ratio, 2.83; 95% CI, 1.87 to 4.28; P < .001). Persons residing in rural areas and those with lower incomes benefitted at the same level as did urban residents. Remote personalized interventions that consider family history and incorporate evidence-based risk communication and behavior change strategies may promote risk-appropriate screening in close relatives of patients with CRC.

    ABSTRACT: Although guidelines recommend in-person counseling before BRCA1/BRCA2 gene testing, genetic counseling is increasingly offered by telephone. As genomic testing becomes more common, evaluating alternative delivery approaches becomes increasingly salient. We tested whether telephone delivery of BRCA1/2 genetic counseling was noninferior to in-person delivery. Participants (women age 21 to 85 years who did not have newly diagnosed or metastatic cancer and lived within a study site catchment area) were randomly assigned to usual care (UC; n = 334) or telephone counseling (TC; n = 335). UC participants received in-person pre- and post-test counseling; TC participants completed all counseling by telephone. Primary outcomes were knowledge, satisfaction, decision conflict, distress, and quality of life; secondary outcomes were equivalence of BRCA1/2 test uptake and costs of delivering TC versus UC. TC was noninferior to UC on all primary outcomes. At 2 weeks after pretest counseling, knowledge (d = 0.03; lower bound of 97.5% CI, -0.61), perceived stress (d = -0.12; upper bound of 97.5% CI, 0.21), and satisfaction (d = -0.16; lower bound of 97.5% CI, -0.70) had group differences and confidence intervals that did not cross their 1-point noninferiority limits. Decision conflict (d = 1.1; upper bound of 97.5% CI, 3.3) and cancer distress (d = -1.6; upper bound of 97.5% CI, 0.27) did not cross their 4-point noninferiority limit. Results were comparable at 3 months. TC was not equivalent to UC on BRCA1/2 test uptake (UC, 90.1%; TC, 84.2%). TC yielded cost savings of $114 per patient. Genetic counseling can be effectively and efficiently delivered via telephone to increase access and decrease costs.

    ABSTRACT: This study examines communication about limitations of genomic results interpretation for colon cancer risk during education and counseling of minority participants. As part of a larger study conducted from 2010 to 2012, participants recruited from a large primary care clinic were offered testing for a research panel of 3 genomic markers (single nucleotide polymorphisms or SNPs) for colorectal cancer risk. Genetic counselors conducted pre- and post-test sessions which included discussion of limitations of result interpretation due to the lack of racial/ethnic diversity in research populations from which risk data are derived. Sessions were audio-recorded, transcribed and thematically analyzed. Many participants did not respond directly to this limitation. Among the participants that responded directly to this race-related limitation, many responses were negative. However, a few participants connected the limited minority information about SNPs with the importance of their current research participation. Genetic counselor discussions of this limitation were bio-medically focused with limited explanations for the lacking data. The communication process themes identified included: low immediacy (infrequent use of language directly involving a participant), verbal dominance (greater speaking ratio of the counselor to the patient) and wide variation in the degree of interactivity (or the amount of turn-taking during the discussion). Placed within the larger literature on patient-provider communication, these present results provide insight into the dynamics surrounding race-related educational content for genomic testing and other emerging technologies. Clinicians may be better able to engage patients in the use of new genomic technology by increasing their awareness of specific communication processes and patterns during education or counseling sessions.

    ABSTRACT: It is recommended that persons having familial risk of colorectal cancer begin regular colonoscopy screening at an earlier age than those in the general population. However, many individuals at increased risk do not adhere to these screening recommendations. The goal of this study was to examine cognitive, affective, social, and behavioral motivators of colonoscopy intention among individuals at increased risk of familial colorectal cancer. Relatives of colorectal cancer cases (N = 481) eligible for colonoscopy screening completed a survey assessing constructs from several theoretical frameworks including fear appeal theories. Structural equation modeling indicated that perceived colorectal cancer risk, past colonoscopy, fear of colorectal cancer, support from family and friends, and health-care provider recommendation were determinants of colonoscopy intention. Future interventions to promote colonoscopy in this increased risk population should target the factors we identified as motivators. (ClinicalTrials.gov number NCT01274143).

    ABSTRACT: To assess the effectiveness of health screening interventions aimed at enhancing informed choice. Studies were selected if (1) they were randomized controlled trials conducted between January 1, 2000, and March 30, 2010, (2) participants in one arm underwent a prescreening intervention aimed at improving informed choice, and (3) informed choice was the primary outcome. Eight studies that met the inclusion criteria involved screening for prostate, colorectal and breast cancer, and diabetes. Five of the 8 prescreening interventions led to greater informed choice. With researchers mindful of the limited number of studies, findings were encouraging, but conclusions regarding the most effective ways of facilitating informed choice for screening are at best tentative.

    ABSTRACT: BACKGROUND: Colonoscopy is one of the most effective methods of cancer prevention and detection, particularly for individuals with familial risk. Recruitment of family members to behavioral intervention trials remains uniquely challenging, due to the intensive process required to identify and contact them. Recruiting at-risk family members requires contacting the original cancer cases and asking them to provide information about their at-risk relatives, who must then be contacted for study enrollment. Though this recruitment strategy is common in family trials, few studies have compared influences of case and relative participation to non-participation. Furthermore, although use of cancer registries to identify initial cases has increased, to our knowledge no study has examined the relationship between registries and family recruitment outcomes. METHODS: This study assessed predictors of case participation and relative enrollment in a recruitment process which utilized state cancer registries. Participation characteristics were analyzed with separate multivariable logistic regressions in three stages: 1) cancer registry-contacted colorectal cancer (CRC) cases who agreed to study contact; 2) study-contacted CRC cases who provided at-risk relative information; and 3) at-risk relatives contacted for intervention participation. RESULTS: Cancer registry source was predictive of participation for both CRC cases and relatives, though relative associations (OR's) varied across registries. Cases were less likely to participate if they were of Hispanic ethnicity or nonwhite, and were more likely to participate if they were female or younger than 50 at cancer diagnosis. At-risk relatives were more likely to participate if they were from Utah, if another family member was also participating in the study, or if they had previously had a colonoscopy. The number of eligible cases who had to be contacted in order to enroll one eligible relative varied widely by registry, from a low ratio of 7:1 to a high ratio of 81:1. CONCLUSIONS: Family recruitment utilizing cancer registry-identified cancer cases is feasible, but highly dependent on both the strategies and protocols of those who are recruiting and on participant characteristics such as gender, race, and geography. Devising comprehensive recruitment protocols that specifically target those less likely to enroll may help future research meet recruitment goals.Trial registration: Family Colorectal Cancer Awareness and Risk Education Project NCT01274143.

    ABSTRACT: We conducted a translational genomics pilot study to evaluate the impact of genomic information related to colorectal cancer (CRC) risk on psychosocial, behavioral and communication outcomes. In 47 primary care participants, 96% opted for testing of three single nucleotide polymorphisms (SNPs) related to CRC risk. Participants averaged 2.5 of 6 possible SNP risk alleles (10% lifetime risk). At 3-months, participants did not report significant increases in cancer worry/distress; over half reported physical activity and dietary changes. SNP risk scores were unrelated to behavior change at 3-months. Many participants (64%) shared their SNP results, including 28% who shared results with a physician. In this pilot, genomic risk education, including discussion of other risk factors, appeared to impact patients' health behaviors, regardless of the level of SNP risk. Future work can compare risk education with and without SNP results to evaluate if SNP information adds value to existing approaches.

    ABSTRACT: Although single nucleotide polymorphism (SNP) testing for disease susceptibility is commercially available, translational studies are necessary to understand how to communicate genomic information and potential implications for public health. We explored attitudes about and initial responses to genomic testing for colon cancer risk. Following development of the educational materials, we offered testing for three colon cancer SNPs in a pilot study with primary care patients. Participants completed pre- and post-test sessions and interviews. We analyzed interview transcripts with qualitative software using thematic analysis. All 20 participants opted for SNP testing. Qualitative analysis identified several themes: Motivations for SNP Testing, Before/After: Meaning of Results, Emotional Responses to SNP Results and Genomic Literacy/ Information Delivery. Results demonstrate that individuals will pursue SNP testing in the context of pre and post-test education. SNP results may influence health behaviors like healthy eating and exercise yet did not appear to impact colon cancer screening intentions.

    ABSTRACT: OBJECTIVE: The development and increased use of genomic profiling has led to refinement of breast cancer treatment. This study sought to examine medical and surgical oncologists' perceptions of factors related to the translation and integration of Oncotype DX® (Genomic Health, Inc., Redwood City, CA, USA) into routine clinical care. METHODS: Twenty oncologists (10 medical and 10 surgical oncologists) participated in qualitative interviews. Questions centered on the following themes: oncologists' perceptions about the clinical utility of testing, the impact of patient preferences on the decision to test and use results to inform treatment decisions, methods of communicating risk associated with test results to patients, and benefits of and barriers to incorporating testing into multidisciplinary care settings. RESULTS: Oncologists found Oncotype DX test results useful in their practice but had concerns as well. These included that some oncologists either used testing inappropriately or placed undue emphasis on the results at the expense of other clinical information. The use of intermediate test results, which have less clear clinical implications, incorporating results with patient treatment preferences, and the use of testing in multidisciplinary teams were noted as specific challenges. CONCLUSION: Oncologists noted several benefits of testing and also many challenges, despite wide dissemination and common use. Education for health providers should include specific training in how to interpret and communicate the uncertainty inherent in genomic tests while integrating patient preferences to inform treatment decision making.

    ABSTRACT: OBJECTIVE: Screening asymptomatic men for prostate cancer is controversial and informed decision making is recommended. Within two prostate cancer screening programs, we evaluated the impact of a print-based decision aid (DA) on decision-making outcomes. METHODS: Men (N=543) were 54.9 (SD=8.1) years old and 61% were African-American. The 2(booklet type: DA vs. usual care (UC))×2(delivery mode: Home vs. Clinic) randomized controlled trial assessed decisional and screening outcomes at baseline, 2-months, and 13-months. RESULTS: Intention-to-treat linear regression analyses using generalized estimating equations revealed that DA participants reported improved knowledge relative to UC (B=.41, p<.05). For decisional conflict, per-protocol analyses revealed a group by time interaction (B=-.69, p<.05), indicating that DA participants were less likely to report decisional conflict at 2-months compared to UC participants (OR=.49, 95% CI: .26-.91, p<.05). CONCLUSION: This is the first randomized trial to evaluate a DA in the context of free mass screening, a challenging setting in which to make an informed decision. The DA was highly utilized by participants, improved knowledge and reduced decisional conflict. PRACTICE IMPLICATIONS: These results are valuable in understanding ways to improve the decisions of men who seek screening and can be easily implemented within many settings.

    ABSTRACT: BACKGROUND: Recent trends suggest that bilateral mastectomy (BM) is on the rise among women diagnosed with unilateral breast cancer. Few studies have investigated the factors associated with the decision to have more aggressive surgery among young, high risk patients. METHODS: As part of a larger study, 284 women aged 50 and under completed an initial survey within 6 weeks of a breast cancer diagnosis. We assessed sociodemographics, medical and family history variables, treatment recommendations, preferences and concerns, distress, perceived risk, knowledge, and neuroticism. We used multiple regression with backward entry to assess the relationship between these variables and our outcomes of decisional conflict and intentions for BM. RESULTS: Higher decisional conflict was associated with being less educated, unmarried, more anxious and less likely to have received a surgical recommendation. Preference for BM was associated with higher neuroticism, perceived risk for contralateral breast cancer, pre-testing risk of carrying a BRCA1/2 mutation, having received either a surgical recommendation (vs. no recommendation), and lower preference for lumpectomy. CONCLUSIONS: For younger women, a surgical recommendation is associated with lower decisional conflict and stronger intention for BM. Results highlight the importance of effective risk communication and decision support between a woman and her surgeon. J. Surg. Oncol © 2012 Wiley Periodicals, Inc.

    ABSTRACT: Low use of BRCA counseling and testing services among black women has been reported in several studies, even though such services may play an important role in reducing racial disparities in breast cancer. Surprisingly, little is known about the extent to which black women at high risk for BRCA mutations actually receive recommendations for BRCA counseling. Thus, a primary goal of the current study was to identify sociodemographic and clinical factors associated with the receipt of physician recommendation for genetic counseling based on the self-report of black women at high risk for BRCA mutations. In this cross-sectional study, participants were 125 black women with a family history suggestive of a hereditary breast and/or ovarian cancer syndrome. Participants were asked about their receipt of genetic counseling recommendation or referral. Physician recommendation was reported by over two-thirds of the sample. Multivariate analyses revealed that older age and study recruitment source, specifically community-based recruitment, were significantly and independently associated with lower likelihood of physician recommendation. Findings highlight the need for additional research to identify subgroups of high-risk black women among whom physician recommendation of genetic counseling is low but would benefit from such counseling.

    ABSTRACT: BACKGROUND: Research comparing the effects of culturally targeted and generic but linguistically appropriate intervention programs is limited. We conducted a randomized controlled trial comparing the efficacy of a culturally targeted video, a generic video, and a fact sheet (control) in promoting mammography screening among Chinese-American immigrants.METHODS: We randomized 664 Chinese-American women from the Washington, DC, and New York City areas who were older than 40 years and nonadherent to annual mammography screening guidelines to three study arms (each with ∼221 women). The outcome was self-reported mammography screening 6 months post intervention. Measures of knowledge, Eastern cultural views, and health beliefs were administered before and after the intervention.RESULTS: The culturally targeted video, the generic video, and the fact sheet increased mammography use by 40.3%, 38.5%, and 31.1% from baseline, respectively. A significant intervention effect was observed only in one subgroup: The culturally targeted video significantly increased mammography screening among low-acculturated women over the fact sheet [OR, 1.70; 95% confidence interval (CI), 1.04-2.78]. Overall, women who obtained a mammogram during the follow-up period reported significantly fewer barriers to screening after intervention than those who had not obtained screening. Both of the video groups reported fewer barriers after intervention than the control group.CONCLUSIONS: Both theoretically guided videos increased the likelihood of mammography use to a similar extent. Cultural targeting was only effective for low-acculturated women. Both videos reduced perceived barriers to screening and consequently increased screening behavior.Impact: The results of this study provide empirical evidence on the efficacy of cultural targeting for minority immigrants.

    ABSTRACT: Despite significant progress in genomics research over the past decade, we remain years away from the integration of genomics into routine clinical care. As an initial step toward the implementation of genomic-based medicine, we explored primary care patients' ideas about genomic testing for common complex diseases to help develop future patient education materials and interventions to communicate genomic risk information. We conducted a mixed-methods study with participants from a large primary care clinic. Within four focus groups, we used a semi-structured discussion guide and administered brief pre- and post- discussion quantitative surveys to assess participants' interest, attitudes, and preferences related to testing and receipt of test results. Prior to the discussion, moderators presented a plain-language explanation of DNA and genetics, defined "SNP", and highlighted what is known and unknown about the risks associated with testing for SNPs related to colorectal cancer risk. We used the NVIVO 8 software package to analyze the transcripts from the focus group discussions. The majority of participants (75 %) were "very" or "somewhat interested" in receiving information from a colon cancer SNP test, even after learning about and discussing the small and still clinically uncertain change in risk conferred by SNPs. Reported interest in testing was related to degree of risk conferred, personal risk factors, family history, possible implications for managing health /disease prevention and curiosity about genetic results. Most people (85 %) preferred that genetic information be delivered in person by a healthcare or genetics professional rather than through print materials or a computer. These findings suggest that patients may look to genetic counselors, physicians or other healthcare professionals as gatekeepers of predictive genomic risk information.

    ABSTRACT: Little is known about psychological distress among women of African descent who are at high risk for a BRCA mutation. This is a group for whom breast cancer risk reduction is critical due to the group's high rates of breast cancer mortality. Distress is important to consider as it may reduce the potential benefit of genetic counseling and negatively affect decision making related to risk reduction. The goals of the current study were to examine breast cancer-specific distress and depressive symptoms in women of African descent at who are at high risk for a BRCA mutation and to identify background factors associated with these outcomes. Participants were 148 high-risk African American and Caribbean women who were part of a larger study that offered participants BRCA counseling at no cost. Participants completed the Impact of Events Scale, which assessed breast cancer-specific distress, and the Center of Epidemiological Studies-Depression Scale, which assessed depressive symptoms. Results of analyses revealed that almost half of the sample achieved scores indicating high and clinically significant breast cancer-specific distress, while almost one-third had clinically significant depression scores. Results further showed that low income was significantly associated with cancer-specific distress, while having a cancer diagnosis was significantly associated with depressive symptoms. These results underscore the need for targeted psychological support throughout the genetic risk assessment process for this particular high-risk group.

    ABSTRACT: Numerous studies have documented the short-term impact of BRCA1/BRCA2 (BRCA1/2) testing; however, little research has examined the long-term impact of testing. We conducted the first long-term prospective study of psychosocial outcomes in a U.S. sample of women who had BRCA1/2 testing. Participants were 464 women who underwent genetic testing for BRCA1/2 mutations. Prior to testing, we measured sociodemographics, clinical variables, and cancer specific and general distress. At long-term follow-up (Median = 5.0 years; Range = 3.4-9.1 years), we assessed cancer-specific and genetic testing distress, perceived stress, and perceived cancer risk. We evaluated the impact of BRCA1/2 test result and risk-reducing surgery on long-term psychosocial outcomes. Among participants who had been affected with breast or ovarian cancer, BRCA1/2 carriers reported higher genetic testing distress (β = 0.41, P < 0.0001), uncertainty (β = 0.18, P < 0.0001), and perceived stress (β = 0.17, P = 0.005) compared with women who received negative (i.e., uninformative) results. Among women unaffected with breast/ovarian cancer, BRCA1/2 carriers reported higher genetic testing distress (β = 0.39, P < 0.0001) and lower positive testing experiences (β = 0.25, P = 0.008) than women with negative results. Receipt of risk-reducing surgery was associated with lower perceived cancer risk (P < 0.0001). In this first prospective long-term study in a U.S. sample, we found modestly increased distress in BRCA1/2 carriers compared with women who received uninformative or negative test results. Despite this modest increase in distress, we found no evidence of clinically significant dysfunction. Although a positive BRCA1/2 result remains salient among carriers years after testing, testing does not seem to impact long-term psychologic dysfunction.
