RESUMO
BACKGROUND: Recently approved treatments and updates to genetic testing recommendations for prostate cancer have created a need for correlated analyses of patient outcomes data via germline genetic mutation status. Genetic registries address these gaps by identifying candidates for recently approved targeted treatments, expanding clinical trial data examining specific gene mutations, and understanding effects of targeted treatments in the real-world setting. METHODS: The PROMISE Registry is a 20-year (5-year recruitment, 15-year follow-up), US-wide, prospective genetic registry for prostate cancer patients. Five thousand patients will be screened through an online at-home germline testing to identify and enroll 500 patients with germline mutations, including: pathogenic or likely pathogenic variants and variants of uncertain significance in genes of interest. Patients will be followed for 15 years and clinical data with real time patient reported outcomes will be collected. Eligible patients will enter long-term follow-up (6-month PRO surveys and medical record retrieval). As a virtual study with patient self-enrollment, the PROMISE Registry may fill gaps in genetics services in underserved areas and for patients within sufficient insurance coverage. RESULTS: The PROMISE Registry opened in May 2021. 2114 patients have enrolled to date across 48 US states and 23 recruiting sites. 202 patients have met criteria for long-term follow-up. PROMISE is on target with the study's goal of 5000 patients screened and 500 patients eligible for long-term follow-up by 2026. CONCLUSIONS: The PROMISE Registry is a novel, prospective, germline registry that will collect long-term patient outcomes data to address current gaps in understanding resulting from recently FDA-approved treatments and updates to genetic testing recommendations for prostate cancer. Through inclusion of a broad nationwide sample, including underserved patients and those unaffiliated with major academic centers, the PROMISE Registry aims to provide access to germline genetic testing and to collect data to understand disease characteristics and treatment responses across the disease spectrum for prostate cancer with rare germline genetic variants.

OBJECTIVE: Universal screening of endometrial carcinoma (EC) for mismatch repair deficiency (MMRd) and Lynch syndrome uses presence of MLH1 methylation to omit common sporadic cases from follow-up germline testing. However, this overlooks rare cases with high-risk constitutional MLH1 methylation (epimutation), a poorly-recognized mechanism that predisposes to Lynch-type cancers with MLH1 methylation. We aimed to determine the role and frequency of constitutional MLH1 methylation among EC cases with MMRd, MLH1-methylated tumors. METHODS: We screened blood for constitutional MLH1 methylation using pyrosequencing and real-time methylation-specific PCR in patients with MMRd, MLH1-methylated EC ascertained from (i) cancer clinics (n = 4, <60 years), and (ii) two population-based cohorts; "Columbus-area" (n = 68, all ages) and "Ohio Colorectal Cancer Prevention Initiative (OCCPI)" (n = 24, <60 years). RESULTS: Constitutional MLH1 methylation was identified in three out of four patients diagnosed between 36 and 59 years from cancer clinics. Two had mono-/hemiallelic epimutation (â¼50% alleles methylated). One with multiple primaries had low-level mosaicism in normal tissues and somatic "second-hits" affecting the unmethylated allele in all tumors, demonstrating causation. In the population-based cohorts, all 68 cases from the Columbus-area cohort were negative and low-level mosaic constitutional MLH1 methylation was identified in one patient aged 36 years out of 24 from the OCCPI cohort, representing one of six (â¼17%) patients <50 years and one of 45 patients (â¼2%) <60 years in the combined cohorts. EC was the first/dual-first cancer in three patients with underlying constitutional MLH1 methylation. CONCLUSIONS: A correct diagnosis at first presentation of cancer is important as it will significantly alter clinical management. Screening for constitutional MLH1 methylation is warranted in patients with early-onset EC or synchronous/metachronous tumors (any age) displaying MLH1 methylation.

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

BACKGROUND AND OBJECTIVES: Many newly diagnosed breast cancer patients do not receive genetic counseling and testing at the time of diagnosis. We examined predictors of genetic testing (GT) in this population. METHODS: Within a randomized controlled trial of proactive rapid genetic counseling and testing vs usual care, patients completed a baseline survey within 6 weeks of breast cancer diagnosis but before a definitive survey. We conducted a multinomial logistic regression to identify predictors of GT timing/uptake. RESULTS: Having discussed GT with a surgeon was a dominant predictor (χ2 (2, N = 320) = 70.13; P < .0001). Among those who discussed GT with a surgeon, patients who had made a final surgery decision were less likely to receive GT before surgery compared with postsurgically (OR [odds ratio] = 0.24; 95% confidence interval [CI] = 0.12-0.49) or no testing (OR = 0.28; 95% CI = 0.14-0.56). Older patients (OR = 0.95; 95% CI = 0.91-0.99) and participants enrolled in New York/New Jersey (OR = 0.22; 95% CI = 0.07-0.72) were less likely to be tested compared with receiving results before surgery. Those with higher perceived risk (OR = 1.02; 95% CI = 1.00-1.03) were more likely to receive results before surgery than to not be tested. CONCLUSIONS: This study highlights the role of patient-physician communication about GT as well as patient-level factors that predict presurgical GT.

OBJECTIVES: Using a novel measure, examine maternal perceptions of the process by which issues pertaining to family communication of BRCA test results are addressed during cancer genetic counseling. METHODS: After receiving BRCA results, mothers (N = 211) of minor-age children reported on their counseling experiences with providers using a communication process measure as well as other psychosocial variables. RESULTS: The novel Genetic Counseling Communication Process measure demonstrated good internal consistency of its 2 factors: patient-led communication (Cronbach's α = 0.73) and provider-led communication (Cronbach's α = 0.82). Participants most often reported that discussions about family communication of BRCA test results to children and adult relatives were led only by their providers (38.2%-39.2%), as opposed to being led by the patient, both parties, or neither party. Providers were most likely to lead these discussions when mothers had stronger family histories of cancer and expressed more confidence about making a decision to talk to their children about BRCA. However, mothers typically led such discussions if they were raising older children and held more positive attitudes about pediatric BRCA testing. CONCLUSIONS: When the assessment of BRCA genetic counseling outcomes includes family communication to potentially at-risk relatives, we learned that most but not all sessions addressed this topic. Cancer family history, child age, and maternal attitudes are important co-factors in these patient-provider communication exchanges. Providers delivering BRCA genetic counseling should be attentive to mothers' information and support needs regarding communicating cancer genetic test results to at-risk relatives, including children.

Telephone genetic counseling (TC) for hereditary breast/ovarian cancer risk has been associated with positive outcomes in high risk women. However, little is known about how patients perceive TC. As part of a randomized trial of TC versus usual care (UC; in-person genetic counseling), we compared high risk women's perceptions of: (1) overall satisfaction with genetic counseling; (2) convenience; (3) attentiveness during the session; (4) counselor effectiveness in providing support; and (5) counselor ability to recognize emotional responses during the session. Among the 554 participants (TC, N = 272; UC, N = 282), delivery mode was not associated with self-reported satisfaction. However, TC participants found counseling significantly more convenient than UC participants (OR = 4.78, 95 % CI = 3.32, 6.89) while also perceiving lower levels of support (OR = 0.56, 95 % CI = 0.40-0.80) and emotional recognition (OR = 0.53, 95 % CI = 0.37-0.76). In exploratory analyses, we found that non-Hispanic white participants reported higher counselor support in UC than in TC (69.4 % vs. 52.8 %; OR = 3.06, 95 % CI = 1.39-6.74), while minority women perceived less support in UC vs. TC (58.3 % vs. 38.7 %; OR = 0.80, 95 % CI = 0.39-1.65). We discuss potential research and practice implications of these findings which may further improve the effectiveness and utilization of TC.

Information on the prevalence of deleterious BRCA1 and BRCA2 (BRCA1/2) mutations in clinic-based populations of Black women is limited. In order to address this gap, we performed a retrospective study to determine the prevalence of deleterious BRCA1/2 mutations, predictors of having a mutation, and acceptance of risk-reducing surgeries in Black women. In an urban unselected clinic-based population, we evaluated 211 self-identified Black women who underwent genetic counseling for hereditary breast-ovarian cancer syndrome. BRCA1/2 mutations were identified in 13.4% of the participants who received genetic testing. Younger age at diagnosis, higher BRCAPRO score, significant family history, and diagnosis of triple-negative breast cancer were associated with identification of a BRCA1/2 mutation. Of the affected patients found to have a deleterious mutation, almost half underwent prophylactic measures. In our study population, 1 in 7 Black women who underwent genetic testing harbored a deleterious BRCA1/2 mutation independent of age at diagnosis or family history.

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 17 6, 467-475.

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.

Family communication is the primary, initial means of educating the next, at-risk generation about hereditary cancer risk. In this study, in-depth parent narratives provided self-report of motivations, planning, satisfactions and regrets associated with sharing or not sharing maternal BRCA1/2 test results with young children and advice for parents considering disclosure and for genetic counselors. Interviews were conducted with 32 mothers tested for BRCA1/2 with children ages 8-21 years and 24 of their co-parents; interview narratives were analyzed qualitatively. Parents were concerned with both protecting and educating children about hereditary cancer risk. They expressed confidence that parents can constructively convey genetic information to minor children. Telling relieved most parents and satisfied a sense of parental duty. Parents strongly advised child-specific, age-appropriate tailoring of genetic information and emphasized conveying the positive, preventive utility of genetic information to children. Immunizing effects of disclosure were viewed as providing forewarning about and preparation for possible later family cancer diagnoses. Parents choosing not to tell children were advised to consider future disclosure. Narratives about parental sharing of BRCA1/2 test results with minor children support the feasibility of parental discussion of maternal genetic test results to the next at-risk generation. Results suggest development of intervention tools for parents would support decision-making and family communication and potentially reduce parental worry and regret. Recommendations are made for more active involvement by genetic counselors with tested parents around the topic of delivery of genetic information to children.

Objective: Evaluate the impact of a targeted family communication intervention for mothers undergoing genetic counseling and testing (GCT) for BRCA gene alterations. Methods: Following BRCA GCT, mothers (N = 204; M age = 45 y) were randomized to either a control condition (self-help print materials) or intervention (printed decision support guide, based on behavioral decision making theory in health care) for supporting choices about disclosing maternal genetic test results to children and adolescents. Behavioral assessments were administered prior to maternal GCT and after receipt of results: primary outcomes were maternal disclosure to children and parent-child communication quality. Results: Mothers in the intervention were > 2x likely to disclose their BRCA test results to their children compared to those in the control condition (odds ratio [OR] = 2.33, 95% confidence interval [CI] = 1.06, 5.10; p = .04). This effect was moderated by children's ages: mothers of preteens (<13 y) assigned to the intervention were >3x likely to disclose their results (OR = 3.74, 95% CI = 1.49, 9.41; p = .005). In adjusted models, intervention was also associated with favorable changes in the quality of parent-child communication (95% CI = 0.30, 9.00; p < .05). Conclusion: Decision support improves parent-child communication outcomes about GCT for hereditary breast-ovarian cancer. Innovation: This trial is among the first to empirically evaluate the outcomes of a behavioral intervention to support family communication of maternal BRCA risk information to children.
RESUMO
BACKGROUND: Spouses and partners ("partners") of women at-risk for ("previvors") and surviving with hereditary breast/ovarian cancer are a primary source of support within their families. Yet, little is known about partners' needs for psychoeducational intervention to enhance their cancer risk knowledge, coping, and support role functioning. OBJECTIVE: To determine the type and range of need for psychoeducational intervention among partners of hereditary breast cancer previving and surviving women, and to understand the potential role of the Internet and other communication channels in meeting that need. METHODS: We conducted a secondary data analysis on partners' needs that were originally assessed via an online community-based organization devoted to hereditary breast cancer. Partners' demographic characteristics, need for psychoeducation, and likelihood of using various communication channels were assessed along with other constructs. Analyses examined commonly-occurring clusters of likely intervention use and by communication channel. RESULTS: Partners (n =143) endorsed a moderately high level of need for psychoeducation and did so across multiple content areas (e.g., role functioning, decision making, communication, intimacy). Factor analysis identified three commonly-preferred communication channels: 1) self-help materials, 2) online interactions, and 3) interpersonal interactions. A cluster analysis among these factors identified three groups of partners based on their likelihood of psychoeducational intervention use (low [18%], moderate [55%], and high [27%] users). In a covariate-adjusted MANOVA, moderate and high intervention users reported significantly greater need for psychoeducation compared to low users (F(2,132) = 9.15, P < .001). CONCLUSIONS: A majority of assessed partners perceived a need for psychoeducational interventions surrounding hereditary breast cancer risk. Internet-based, interactive resources may be an efficient mechanism to reach large numbers of partners with tailored content. Research is warranted to inform the design and deployment of these resources to ensure quality and high impact, and ultimately to examine ways to integrate these resources into clinical care.

Patient engagement in medical decision-making improves patient related outcomes through compliance and patient satisfaction. The Inova Schar Cancer Institute has a weekly molecular tumor board (MTB) to match comprehensive genomic sequencing results with targeted therapies for patients. Primary oncologists extended MTB invitations to their patients. Ultimately, 20 of the 139 patients attended and completed pre- and post MTB surveys. There was a statistically significant change from the pre- to post- survey for the question "I am satisfied with how well informed I am about targeted therapy" with P = 0.016. Patients who attended MTB reported higher levels of satisfaction with their knowledge of targeted therapy after MTB as compared to before. A more holistic method of studying this practice would include sampling a larger patient population and a formal evaluation of the physicians' experience with patients attending.

BACKGROUND: It is important to examine adolescent and young adult (AYA) children's long-term psychosocial and behavioral adaptation to disclosure of maternal BRCA-positive carrier status (BRCA+) to inform approaches for familial cancer risk communication, education, and counseling. METHODS: Mothers underwent BRCA genetic testing 1 to 5 years earlier. Group differences in AYAs' self-reported outcomes were analyzed by maternal health and carrier status, and child age and sex. RESULTS: A total of N = 272 AYAs were enrolled: 76.1% of their mothers were breast or ovarian cancer survivors and 17.3% were BRCA+. AYAs' cancer risk behavior (tobacco and alcohol use, physical activity) and psychologic distress levels did not vary by maternal status. In bivariate analyses, AYAs of cancer-surviving mothers believed themselves to be at greater risk for, and were more knowledgeable about, cancer than AYAs of mothers without cancer. AYAs of BRCA+ mothers were more concerned about cancer, held stronger beliefs about genetic risk, and placed a higher value on learning about genetics. In adjusted models, maternal cancer history (not BRCA+) remained associated with AYAs' greater perceptions of cancer risk (P = .002), and knowledge about cancer (P = .03) and its causes (P = .002). CONCLUSIONS: Disclosing maternal BRCA+ status did not influence children's lifestyle behavior or adversely affect quality of life long term. AYAs of BRCA+ mothers were more aware of and interested in genetic risk information. Such families may benefit from support to promote open communication about genetic testing choices.

PURPOSE: Telegenetics has become the predominant mode of cancer genetic counseling during the COVID-19 pandemic. We sought to identify potential patient-level contraindicators for telegenetic genetic counseling. METHODS: We analyzed post-counseling (pre-result disclosure) follow-up data from a randomized noninferiority trial of a telephone genetic counseling versus usual care genetic counseling. Among 669 randomized participants, 600 completed pre-test counseling and 568 completed a 2-week follow-up assessment before receiving test results. In this analysis, we focused on genetic counseling outcomes (knowledge, decisional conflict, and distress). In multivariate models controlling for bivariate predictors of these outcomes, we tested our a priori hypotheses that pre-counseling numeracy, perceived stress, and race/ethnicity would moderate the outcomes of telephone genetic counseling versus usual care. RESULTS: Only numeracy significantly moderated associations between mode of genetic counseling and outcomes. Higher numeracy was associated with higher post-counseling knowledge following telephone genetic counseling (p < 0.001), but not usual care (p = 0.450). Higher numeracy was also associated with lower distress following telephone genetic counseling (p = 0.009) but not usual care (p = 0.16). Neither perceived stress nor race/ethnicity exhibited differential impacts on telephone genetic counseling versus usual care (ps > 0.20). CONCLUSION: Although high numeracy was associated with higher levels of knowledge following telegenetic counseling, we did not identify any clinically significant patient-level contraindicators for telegenetic counseling. These results lend further confidence to the broad use of telegenetics.
RESUMO
Women who receive positive or uninformative BRCA1/2 test results face a number of decisions about how to manage their cancer risk. The purpose of this study was to prospectively examine the effect of receiving a positive versus uninformative BRCA1/2 genetic test result on the perceived pros and cons of risk-reducing mastectomy (RRM) and risk-reducing oophorectomy (RRO) and breast cancer screening. We further examined how perceived pros and cons of surgery predict intention for and uptake of surgery. 308 women (146 positive, 162 uninformative) were included in RRM and breast cancer screening analyses. 276 women were included in RRO analyses. Participants completed questionnaires at pre-disclosure baseline and 1-, 6-, and 12-months post-disclosure. We used linear multiple regression to assess whether test result contributed to change in pros and cons and logistic regression to predict intentions and surgery uptake. Receipt of a positive BRCA1/2 test result predicted stronger pros for RRM and RRO (P < 0.001), but not perceived cons of RRM and RRO. Pros of surgery predicted RRM and RRO intentions in carriers and RRO intentions in uninformatives. Cons predicted RRM intentions in carriers. Pros and cons predicted carriers' RRO uptake in the year after testing (P < 0.001). Receipt of BRCA1/2 mutation test results impacts how carriers see the positive aspects of RRO and RRM and their surgical intentions. Both the positive and negative aspects predict uptake of surgery.

OBJECTIVE: Genetic testing is increasingly part of routine clinical care for women with a family history of breast cancer. Given their substantially elevated risk for breast cancer, BRCA1/BRCA2 mutation carriers must make the difficult decision whether or not to opt for risk reducing mastectomy. To help BRCA1/2 carriers make this decision, the authors developed a computer-based interactive decision aid that was tested against usual care in a randomized controlled trial. DESIGN: After the completion of genetic counseling, 214 female (aged 21-75) BRCA1/BRCA2 mutation carriers were randomized to Usual Care (UC; N = 114) or Usual Care plus Decision Aid (DA; N = 100) arms. UC participants received no additional intervention. DA participants were sent the CD-ROM DA to view at home. MAIN OUTCOME MEASURES: The authors measured final management decision, decisional conflict, decisional satisfaction, and receipt of risk reducing mastectomy at 1-, 6-, and 12-months postrandomization. RESULTS: Longitudinal analyses revealed that the DA was effective among carriers who were initially undecided about how to manage their breast cancer risk. Within this group, the DA led to an increased likelihood of reaching a management decision (OR = 3.09, 95% CI = 1.62, 5.90; p < .001), decreased decisional conflict (B = -.46, z = -3.1, p <002), and increased satisfaction (B = .27, z = 3.1, p = .002) compared to UC. Among carriers who had already made a management decision by the time of randomization, the DA had no benefit relative to UC. CONCLUSION: These results demonstrate that BRCA1/BRCA2 mutation carriers who are having difficulty making a breast cancer risk management decision can benefit from adjunct decision support.

OBJECTIVE: Predictive genetic testing for hereditary breast/ovarian cancer risk (BRCA1/2 testing) is not recommended for minor children due to its lack of immediate medical benefit and potential psychological risk. Yet, tested mothers are often interested in learning about their children's cancer risks via pediatric BRCA1/2 testing, raising a host of bioethical concerns. However, no reliable or valid tool exists to formally gauge parents' interest in such testing. The aim of this study was to develop and evaluate a new measure for use in genetic research and consultation, known as the Pediatric BRCA1/2 Testing Attitudes Scale (P-TAS). METHODS: After pretest genetic counseling and provision of a blood sample for BRCA1/2 testing, the P-TAS was administered to 187 mothers of children between 8- and 21-years-old. The measure was also given to 96 of the mothers' nontested co-parents. Analyses of the factor structure and psychometric properties of the measure were performed in mothers and confirmed in their co-parents. RESULTS: The two factors of the P-TAS, labeled Attitudes and Beliefs (Factor 1) and Decision Making and Communication (Factor 2), accounted for 62.9% of the variance and were reliable (Cronbach's coefficient alphas =.70 and .90, respectively); the structure and properties were largely confirmed among co-parents. Validity was indicated through its convergence with related constructs. CONCLUSIONS: This new tool may be integrated into genetic counseling research to better assess parents' attitudes and interests in pediatric BRCA1/2 testing.

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

Genetic counseling and testing, particularly for adult onset conditions, has become increasingly available over the last decade, and it is expected that this trend will continue as additional genes are identified and as such testing diffuses into mainstream clinical care. To meet the increased demand for services, it will become necessary to explore alternative avenues to traditional face-to-face genetic counseling. One such modality is the use of telephone genetic counseling (TGC), which is easy to implement and still allows for comprehensive service delivery. Although TGC has been used with increased frequency, there is a paucity of data about its effectiveness and impact on important patient outcomes. This paper provides an overview of the evolution of telephone counseling in nongenetics and genetics settings. The rationale and aims of the largest randomized clinical trial to be performed with this mode of counseling in the context of cancer susceptibility testing for mutations in the BRCA1 and BRCA2 genes are also explained. In addition, procedural aspects of the genetic counseling intervention and the novel tools developed to facilitate this process and to ensure adequate counselor training and quality assurance are described.
