Purpose: 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. Patients and Methods: 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. Results: 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. Conclusion: Genetic counseling can be effectively and efficiently delivered via telephone to increase access and decrease costs.

Purpose: Approximately 5% to 10% of newly diagnosed breast cancer patients carry a BRCA1 or BRCA2 mutation. Given these patients' high risk for contralateral breast cancer, bilateral mastectomy is increasingly considered a treatment option for newly diagnosed BRCA1/2 carriers. In the present study, we prospectively evaluated the impact on surgical decision-making of pretreatment genetic counseling and BRCA1/BRCA2 testing among breast cancer patients at high-risk for carrying a mutation. Patients and Methods: Participants were 194 newly diagnosed breast cancer patients who had not yet received definitive surgical treatment and who had at least a 10% prior probability of carrying a BRCA1/2 mutation. Participants were offered free genetic counseling and rapid BRCA1/2 testing. Primary analyses focused on the impact of BRCA1/2 test result on subsequent breast cancer surgical treatment. Results: Forty-eight percent of patients who were found to carry a BRCA1/2 mutation chose bilateral mastectomy as their definitive breast cancer surgery. In contrast, 24% of patients in whom no mutation was detected and 4% of test decliners opted for bilateral mastectomy. Additional predictors of bilateral mastectomy included patients' self-reports of physician recommendations for BRCA1/2 testing and bilateral mastectomy. Conclusion: This study highlights patient interest in and the technical feasibility of offering presurgery BRCA1/2 testing to high-risk patients. Most importantly, these results demonstrate that BRCA1/2 test results significantly affect patients' surgical decision-making. The availability of genetic counseling and testing could serve as a valuable aid to patient decision-making for newly diagnosed breast cancer patients at high-risk for carrying a mutation.

BACKGROUND: For BRCA1/BRCA2 gene testing to benefit public health, mutation carriers must initiate appropriate risk management strategies. There has been little research examining the long‐term use and prospective predictors of the full range of risk management behaviors among women who have undergone BRCA1/2 testing. We evaluated long‐term uptake and predictors of risk‐reducing mastectomy (RRM), risk‐reducing bilateral salpingo‐oophorectomy (RRBSO), chemoprevention, and cancer screening among women at a mean of 5.3 years after testing.METHODS: The study participants comprised 465 women who underwent BRCA1/2 testing. Prior to genetic counseling, we measured family/personal cancer history, sociodemographics, perceived risk, cancer‐specific distress, and general distress. We contacted patients at a mean of 5.3 years after testing to measure use of RRM, RRBSO, chemoprevention, and breast and ovarian cancer screening.RESULTS: Among participants with intact breasts and/or ovaries at the time of testing, BRCA1/2 carriers were significantly more likely to obtain RRM (37%) and RRBSO (65%) compared with women who received uninformative (RRM, 6.8%; RRBSO, 13.3%) or negative (RRM, 0%; RRBSO, 1.9%) results. Among carriers, precounseling anxiety was associated with subsequent uptake of RRM. RRO was predicted by age. Carriers were also more likely have used breast cancer chemoprevention and have undergone magnetic resonance imaging screening.CONCLUSION: This prospective evaluation of the uptake and predictors of long‐term management outcomes provides a clearer picture of decision making in this population. At a mean of 5.3 years after testing, more than 80% of carriers had obtained RRM, RRBSO, or both, suggesting that BRCA1/2 testing is likely to have a favorable effect on breast and ovarian cancer outcomes.

Purpose: Despite the widespread availability of genetic testing for BRCA1/BRCA2 mutations, little is known about the impact of testing on ovarian cancer prevention and screening. For mutation testing to effect cancer mortality, positive test results must be followed by appropriate behavior change. In this study, we prospectively examined the impact of BRCA1/2 testing on the utilization of prophylactic oophorectomy and ovarian cancer screening. Participants and Methods: Participants were 289 high-risk women who underwent genetic counseling and testing for alterations in the BRCA1/2 genes. We measured self-reported receipt of bilateral prophylactic oophorectomy (BPO) and utilization of CA-125 and transvaginal ultrasound (TVU) in the year following testing, and examined the impact of test results on these outcomes. In addition, we examined the role of sociodemographic, medical, family history, and psychological variables on the receipt of BPO, CA-125, and TVU. Results: Twenty-seven percent of mutation carriers, 5% of uninformative patients, and 2% of noncarriers received a BPO in the year following testing. In addition to test results, perceived risk for ovarian cancer and family history of ovarian cancer independently predicted receipt of BPO. The receipt of a positive test result was associated with increased utilization of CA-125 and TVU. Additional predictors included perceived risk for ovarian cancer (both CA-125 and TVU) and state anxiety (CA-125). Conclusion: These results demonstrate the significant behavioral impact of receiving a positive BRCA1/2 test result. The increased rate of oophorectomy among mutation carriers suggests that testing for BRCA1/2 mutations may ultimately impact ovarian cancer mortality.

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. 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. The authors measured final management decision, decisional conflict, decisional satisfaction, and receipt of risk reducing mastectomy at 1-, 6-, and 12-months postrandomization. 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. 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.

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.
