Cost-effectiveness of population based BRCA testing with varying Ashkenazi Jewish ancestry. Am J Obstet Gynecol 2017; 217:578.e1-578.e12. [PMID: 28690137 DOI: 10.1016/j.ajog.2017.06.038] [Citation(s) in RCA: 59] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2017] [Revised: 06/22/2017] [Accepted: 06/30/2017] [Indexed: 01/11/2023]
Abstract
BACKGROUND Population-based BRCA1/BRCA2 testing has been found to be cost-effective compared with family history-based testing in Ashkenazi-Jewish women were >30 years old with 4 Ashkenazi-Jewish grandparents. However, individuals may have 1, 2, or 3 Ashkenazi-Jewish grandparents, and cost-effectiveness data are lacking at these lower BRCA prevalence estimates. We present an updated cost-effectiveness analysis of population BRCA1/BRCA2 testing for women with 1, 2, and 3 Ashkenazi-Jewish grandparents. STUDY DESIGN Decision analysis model. METHODS Lifetime costs and effects of population and family history-based testing were compared with the use of a decision analysis model. 56% BRCA carriers are missed by family history criteria alone. Analyses were conducted for United Kingdom and United States populations. Model parameters were obtained from the Genetic Cancer Prediction through Population Screening trial and published literature. Model parameters and BRCA population prevalence for individuals with 3, 2, or 1 Ashkenazi-Jewish grandparent were adjusted for the relative frequency of BRCA mutations in the Ashkenazi-Jewish and general populations. Incremental cost-effectiveness ratios were calculated for all Ashkenazi-Jewish grandparent scenarios. Costs, along with outcomes, were discounted at 3.5%. The time horizon of the analysis is "life-time," and perspective is "payer." Probabilistic sensitivity analysis evaluated model uncertainty. RESULTS Population testing for BRCA mutations is cost-saving in Ashkenazi-Jewish women with 2, 3, or 4 grandparents (22-33 days life-gained) in the United Kingdom and 1, 2, 3, or 4 grandparents (12-26 days life-gained) in the United States populations, respectively. It is also extremely cost-effective in women in the United Kingdom with just 1 Ashkenazi-Jewish grandparent with an incremental cost-effectiveness ratio of £863 per quality-adjusted life-years and 15 days life gained. Results show that population-testing remains cost-effective at the £20,000-30000 per quality-adjusted life-years and $100,000 per quality-adjusted life-years willingness-to-pay thresholds for all 4 Ashkenazi-Jewish grandparent scenarios, with ≥95% simulations found to be cost-effective on probabilistic sensitivity analysis. Population-testing remains cost-effective in the absence of reduction in breast cancer risk from oophorectomy and at lower risk-reducing mastectomy (13%) or risk-reducing salpingo-oophorectomy (20%) rates. CONCLUSION Population testing for BRCA mutations with varying levels of Ashkenazi-Jewish ancestry is cost-effective in the United Kingdom and the United States. These results support population testing in Ashkenazi-Jewish women with 1-4 Ashkenazi-Jewish grandparent ancestry.

Abstract
Answer questions and earn CME/CNE Fifteen percent of women with epithelial ovarian cancer have inherited mutations in the BRCA breast cancer susceptibility genes. Knowledge of her BRCA status has value both for the woman and for her family. A therapeutic benefit exists for the woman with cancer, because a new family of oral drugs, the poly ADP-ribose polymerase (PARP) inhibitors, has recently been approved, and these drugs have the greatest efficacy in women who carry the mutation. For her family, there is the potential to prevent ovarian cancer in those carrying the mutation by using risk-reducing surgery. Such surgery significantly reduces the chance of developing this, for the most part, incurable cancer. Despite these potential benefits, referral rates for genetic counseling and subsequent BRCA testing are low, ranging from 10% to 30%, indicating that these therapeutic and prevention opportunities are being missed. The authors have reviewed the relevant available literature. Topics discussed are BRCA and its relation to ovarian cancer, the rates of referral for genetic counseling/BRCA testing, reasons for these low rates, potential strategies to improve on those rates, lack of effectiveness of current screening strategies, the pros and cons of risk-reducing surgery, other prevention options, and the role and value of PARP inhibitors.

Abstract
INTRODUCTION Mutations in either the BRCA1 or BRCA2 genes are responsible for approximately 42,000 cases of breast cancer annually. Identifying these germline mutations in a woman with breast cancer is important because it can influence her immediate and long-term management and has important implications for other family members. Areas covered: This review highlights how treatment-focussed genetic testing for BRCA1 and BRCA2 mutations can potentially influence cancer treatment and secondary prevention decisions in women with breast cancer. Expert commentary: Testing women with breast cancer for BRCA1 and BRCA2 germline mutations has the potential to decrease cancer burden and improve cancer outcomes. It can help optimise surgical and systemic therapy approaches. Clinicians should actively consider whether genetic testing is appropriate for each woman with breast cancer, and if so should instigate it early in the treatment trajectory when it can most influence cancer care.

Abstract
BACKGROUND Women with a BRCA mutation have significantly elevated breast cancer risk, which can be reduced by >90% with bilateral prophylactic mastectomy (BPM). We sought to compare a cohort of BRCA mutation carriers choosing BPM versus breast surveillance to better elucidate factors that may impact decision making. METHODS Women with a BRCA mutation were retrospectively identified from a prospectively maintained database. The surveillance cohort (n = 313) consisted of women seen in a high-risk clinic between 2014 and 2016, while the surgery cohort (n = 142) consisted of women who underwent BPM between 2010 and 2016. Clinical and familial factors were compared between the groups. RESULTS Women choosing BPM were more likely to have a BRCA1 than BRCA2 mutation compared with the surveillance group (57 vs. 45%, p = 0.02) and were less likely to have a personal history of ovarian cancer (10 vs. 20%, p = 0.01). Furthermore, women undergoing BPM were more likely to be married (78 vs. 62%, p = 0.01), to have more children (median 2 vs. 1, p < 0.001), and to have undergone a prophylactic oophorectomy (61 vs. 37%, p < 0.001). Women choosing BPM had more first-degree relatives (63 vs. 48%, p = 0.01) or a sister (23 vs. 14%, p = 0.02) with a history of breast cancer and were more likely to have a family member with ovarian cancer under the age of 40 years (9 vs. 4%, p = 0.03). There was no difference in the number of prior breast biopsies or history of atypia/lobular carcinoma in situ. CONCLUSION The decision to undergo BPM appears multifactorial, with gene mutation, family history, and relationships appearing to have the strongest influence on decision making.

Abstract
Purpose Unaffected women who carry BRCA1 or BRCA2 mutations face difficult choices about reducing their breast cancer risk. Understanding their treatment preferences could help us improve patient counseling and inform drug trials. The objective was to explore preferences for various risk-reducing options among women with germline BRCA1/2 mutations using a discrete-choice experiment survey and to compare expressed preferences with actual behaviors. Methods A discrete-choice experiment survey was designed wherein women choose between hypothetical treatments to reduce breast cancer risk. The hypothetical treatments were characterized by the extent of breast cancer risk reduction, treatment duration, impact on fertility, hormone levels, risk of uterine cancer, and ease and mode of administration. Data were analyzed using a random-parameters logit model. Women were also asked to express their preference between surgical and chemoprevention options and to report on their actual risk-reduction actions. Women aged 25–55 years with germline BRCA1/2 mutations who were unaffected with breast or ovarian cancer were recruited through research registries at five clinics and a patient advocacy group. Results Between January 2015 and March 2016, 622 women completed the survey. Breast cancer risk reduction was the most important consideration expressed, followed by maintaining fertility. Among the subset of women who wished to have children in future, the ability to maintain fertility was the most important factor, followed by the extent of risk reduction. Many more women said they would take a chemoprevention drug than had actually taken chemoprevention. Conclusions Women with BRCA1/2 mutations indicated strong preferences for breast cancer risk reduction and maintaining fertility. The expressed desire to have a safe chemoprevention drug available to them was not met by current chemoprevention options.

Abstract
BACKGROUND To investigate breast cancer prognosis (disease-free (DFS) and overall survival (OS)) among carriers of germline BRCA mutations (BRCAm) in Denmark. METHODS We identified all women in Central and Northern Denmark diagnosed with breast cancer during 2004-2011. We retrieved information on germline BRCAm testing from Clinical Genetics departments and clinical/treatment characteristics from population-based medical registries. Follow-up for recurrence, new primary cancer, and mortality extended from 180days after diagnosis until 31/12/2012. We estimated median DFS and OS and five-year cumulative incidence and incidence rates (IR/1000 person-years), and 95% confidence intervals (95% CI), for each outcome. RESULTS Among 9874 patients, 523 (5%) underwent BRCA testing-90 were BRCAm carriers, 433 were BRCA wildtype (BRCAwt). Compared with BRCAwt women, BRCAm carriers were younger, had lower stage, and ER- and HER2- tumors. Median time from diagnosis to BRCA testing was 0.91 years and 1.3 years in BRCAm and BRCAwt women; median follow-up to first event was 3.9 and 3.4 years, respectively. Five-year DFS and OS were higher in BRCAm than BRCAwt women: 88% (95%CI=78.3-93.5) vs. 75.3% (95%CI=70.2-79.6) and 97.8% (95%CI=91.4-99.4) vs 92.2% (95%CI=88.5-94.7), respectively. Five-year IRs of recurrence were 36.7/1000 person-years (95%CI=15.8-72.2) in the BRCAm cohort vs. 58.4 (95%CI=42.9-77.6) in the BRCAwt cohort. CONCLUSIONS BRCAm carriers may have a better prognosis than BRCAwt women. However, limited testing conducted mainly during follow-up, yielded low numbers for precise estimations, and may be attributable to selection bias.

Challenging Salpingectomy as a Risk-Reducing Measure for Ovarian Cancer: Histopathological Analysis of the Tubo-Ovarian Interface in Women Undergoing Risk-Reducing Salpingo-oophorectomy. Int J Gynecol Cancer 2017; 27:703-707.

Abstract
ObjectiveOpportunistic bilateral salpingectomy is now promoted for women at the time of hysterectomy for a benign disease, consequent to the fimbrial end of the fallopian tube emerging as the primary site for carcinogenesis in high-grade serous carcinomas. In high-risk women with an identified germ line mutation, bilateral salpingo-oophorectomy offers the greatest risk reduction for ovarian cancer. Currently, no prospective evidence exists with respect to the effectiveness of opportunistic salpingectomy alone in preventing ovarian cancer. Although it is thought that there is no direct connection between the ovary and its adjacent fallopian tube, we often find remnants of the fimbria adherent to the ovary at the time of surgery. If this tubo-ovarian interface is not separate, then practices such as salpingectomy and radical fimbriectomy may be incomplete, and the effectiveness of this technique as a prophylactic strategy may need reconsideration. We aimed to establish whether there might exist a direct attachment of the fimbria to the ovary by examining this interface in surgically removed specimens.MethodsThe tubes and ovaries of 20 women undergoing risk-reducing salpingo-oophorectomy were examined using the Sectioning and Extensively Examining the Fimbriated End of the Tubes protocol and p53 immunohistochemistry for lesions suspicious of serous intraepithelial tubal carcinoma.ResultsThree specimens showed fimbria adherent to the ovary at the histopathological analysis. One p53 signature was identified, but there were no occult cancers or serous intraepithelial tubal carcinomas.ConclusionsAlthough only a small study, the findings show that microscopic fimbriae are adherent to the ovary. This relationship challenges the recommendation for bilateral salpingectomy alone for risk-reducing surgery because the primary site of carcinogenesis may be left on the ovary to later develop into a high-grade serous carcinoma. A larger study is needed to assess our findings related to the tubo-ovarian interface and its implications for long-term ovarian cancer development. Until then, caution on using this technique alone in the high-risk patient should be adopted.

Abstract
Current guidelines recommend that all women with ovarian cancer undergo germline genetic testing for BRCA1/2. Increasingly, genetic testing is being performed via panels that include other genes that confer a high or moderate risk of breast cancer. In addition, many women with a family history of breast or ovarian cancer are not found to have a mutation, but may have increased risk of breast cancer for which surveillance and risk reduction strategies are indicated. This review discusses how to assess and manage an increased risk of breast cancer through surveillance, preventive medications, and risk-reducing surgery. Assessing and managing the increased risk of breast cancer in BRCA1/2 mutation carriers after a diagnosis of ovarian cancer can be challenging. For the first few years after an ovarian cancer diagnosis, BRCA1/2 mutation carriers have a relatively low risk of breast cancer, and their prognosis is largely determined by the ovarian cancer. However, if these women remain in remission after two years, the risk of breast cancer becomes comparable with, and in some cases exceeds, their risk of ovarian cancer recurrence. For these women, breast cancer surveillance and risk reduction becomes important to their overall health. Specifically, for BRCA1/2 carriers who are diagnosed with early-stage ovarian cancer, we recommend regular breast cancer surveillance and consideration of risk reduction with medication and/or prophylactic mastectomy. For women with advanced ovarian cancer who do not achieve remission, breast cancer surveillance or prophylaxis is not of value. However, among carriers with more favorable advanced disease, it is reasonable to initiate breast cancer surveillance. Patients with less favorable advanced stage disease who achieve sustained remission (>2-5years) should also consider more aggressive strategies for breast cancer screening and prevention. For mutation carriers who remain in remission after five years, prophylactic mastectomy can be considered.

Abstract
OBJECTIVE The objective of this study was to review the role of bilateral salpingo-oophorectomy in BRCA mutation (mBRCA) carriers and alternative interventions in risk reduction of ovarian cancer (OC). MATERIALS AND METHODS A systematic review using PubMed, MEDLINE, EMBASE, and the Cochrane library was conducted to identify studies of different strategies to prevent OC in mBRCA carriers, including bilateral salpingo-oophorectomy, prophylactic salpingectomy with delayed oophorectomy, intensive surveillance, and chemoprevention. RESULTS Risk-reducing bilateral salpingo-oophorectomy is an effective intervention, but its associated morbidity is substantial and seems to curtail uptake rates among the target population. Although there is much interest and a strong theoretical basis for salpingectomy with delayed oophorectomy, data on its clinical application are scarce with regard to screening, the use of an algorithmic protocol has recently shown favorable albeit indefinite results in average-risk postmenopausal women. Its incorporation into studies focused on high-risk women might help solidify a future role for screening as a bridge to surgery. The use of oral contraceptives for chemoprevention is well supported by epidemiologic studies. However, there is a lack of evidence for advocating any of the other agents proposed for this purpose, including nonsteroidal anti-inflammatory drugs, vitamin D, and retinoids. CONCLUSION Further studies are needed before salpingectomy with delayed oophorectomy or intensive surveillance can be offered as acceptable, less morbid alternatives to upfront oophorectomy for mBRCA carriers. The Oncologist 2017;22:450-459 IMPLICATIONS FOR PRACTICE: Risk-reducing bilateral salpingo-oophorectomy is currently the most effective method for reducing the risk of ovarian cancer in BRCA mutation (mBRCA) carriers. Unfortunately, it is associated with significant short- and long-term morbidity, stemming from reduced circulating estrogen. In recent years, much research has been devoted to evaluating less morbid alternatives, especially multimodal cancer screening and prophylactic salpingectomy with delayed oophorectomy. This review describes the present state of the art, with the aim of informing the counseling provided to mBRCA carriers on this complicated issue and encouraging additional research to facilitate the incorporation of such alternatives into routine practice.

Abstract
BACKGROUND It is unclear if the use of hormone therapy (HT) in carriers of BRCA mutations improves the quality of life (QOL) without increasing the risk of breast cancer following a risk-reducing salpingo-oophorectomy (RRSO). Our objective was to assess the effect of HT on QOL and breast cancer risk, after RRSO. METHODS We searched MEDLINE, EMBASE, CINHAL, and others, from inception to July 22, 2016, to identify relevant studies. Two reviewers independently screened identified records for controlled trials and observational studies that addressed the effect of HT on QOL and breast cancer risk in women with BRCA mutations, post RRSO. Two reviewers independently extracted data on populations, interventions, comparators, outcomes, and methodological quality. Studies addressing the same outcome were synthesized using written evidence summaries or tables. RESULTS Of the 1,059 records identified, 13 met our inclusion criteria. All studies were observational. Six studies assessed the effect on QOL. Of these, 3 showed improvement in QOL with HT use. The risk of breast cancer was evaluated in 4 studies. The mean duration of follow-up was 2.6 years (range 0.1-19.1). The risk of breast cancer did not change with HT use in all 4 studies. CONCLUSIONS Cumulative evidence from our review suggests that short-term HT use following RRSO improves QOL. The effect on breast cancer risk is still unclear. There are too few long-term studies to draw any strong conclusions. The need for future well-designed RCTs for more established evidence is imperative.

Key messages for communicating information about BRCA1 and BRCA2 to women with breast or ovarian cancer: Consensus across health professionals and service users. Psychooncology 2017; 26:1818-1824. [PMID: 28101941 DOI: 10.1002/pon.4379] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2016] [Revised: 12/26/2016] [Accepted: 01/15/2017] [Indexed: 11/06/2022]
Abstract
BACKGROUND Genetic testing of cancer predisposing genes will increasingly be needed in oncology clinics to target cancer treatment. This Delphi study aimed to identify areas of agreement and disagreement between genetics and oncology health professionals and service users about the key messages required by women with breast/ovarian cancer who undergo BRCA1/BRCA2 genetic testing and the optimal timing of communicating key messages. METHODS Participants were 16 expert health professionals specialising in oncology/genetics and 16 service users with breast/ovarian cancer and a pathogenic BRCA1/BRCA2 variant. Online questionnaires containing 53 inductively developed information messages were circulated to the groups separately. Participants rated each message as key/not key on a Likert scale and suggested additional messages. Questionnaires were modified according to the feedback and up to 3 rounds were circulated. Consensus was reached when there was ≥75% agreement. RESULTS Thirty key messages were agreed by both groups with 7 of the key messages agreed by ≥95% of participants: dominant inheritance, the availability of predictive testing, the importance of pretest discussion, increased risk of breast and ovarian cancer, and the option of risk-reducing mastectomy and bilateral salpingo-oophorectomy. Both groups agreed that key messages should be communicated before genetic testing and once a pathogenic variant has been identified. CONCLUSIONS There was a high level of agreement within and between the groups about the information requirements of women with breast/ovarian cancer about BRCA1/BRCA2. These key messages will be helpful in developing new approaches to the delivery of information as genetic testing becomes further integrated into mainstream oncology services.

Abstract
Background Whether oophorectomy reduces breast cancer risk among BRCA mutation carriers is a matter of debate. We undertook a prospective analysis of bilateral oophorectomy and breast cancer risk in BRCA mutation carriers. Methods Subjects had no history of cancer, had both breasts intact, and had information on oophorectomy status (n = 3722). Women were followed until breast cancer diagnosis, prophylactic bilateral mastectomy, or death. A Cox regression model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of breast cancer associated with oophorectomy (coded as a time-dependent variable). All statistical tests were two-sided. Results Over a mean follow-up of 5.6 years, 350 new breast cancers were diagnosed. Among women with a BRCA1 or BRCA2 mutation, oophorectomy was not associated with breast cancer risk compared with women who did not undergo an oophorectomy. The age-adjusted hazard ratio associated with oophorectomy was 0.96 (95% CI = 0.73 to 1.26, P = 76) for BRCA1 and was 0.65 (95% CI = 0.37 to 1.16, P = 14) for BRCA2 mutation carriers. In stratified analyses, the effect of oophorectomy was statistically significant for breast cancer in BRCA2 mutation carriers diagnosed prior to age 50 years (age-adjusted HR = 0.18, 95% CI = 0.05 to 0.63, P = 007). Oophorectomy was not associated with risk of breast cancer prior to age 50 years among BRCA1 mutation carriers (age-adjusted HR = 0.79, 95% CI = 0.55 to 1.13, P = 51). Conclusions Findings from this large prospective study support a role of oophorectomy for the prevention of premenopausal breast cancer in BRCA2, but not BRCA1 mutation carriers. These findings warrant further evaluation.

A synthesis of qualitative research. Psychooncology 2016; 26:1254-1262.

Abstract
Objective Risk‐reducing procedures can be offered to people at increased cancer risk, but many procedures can have iatrogenic effects. People therefore need to weigh risks associated with both cancer and the risk‐reduction procedure in their decisions. By reviewing relevant literature on breast cancer (BC) risk reduction, we aimed to understand how women at relatively high risk of BC perceive their risk and how their risk perceptions influence their decisions about risk reduction. Methods Synthesis of 15 qualitative studies obtained from systematic searches of SCOPUS, Web of Knowledge, PsychINFO, and Medline electronic databases (inception‐June 2015). Results Women did not think about risk probabilistically. Instead, they allocated themselves to broad risk categories, typically influenced by their own or familial experiences of BC. In deciding about risk‐reduction procedures, some women reported weighing the risks and benefits, but papers did not describe how they did so. For many women, however, an overriding wish to reduce intense worry about BC led them to choose aggressive risk‐reducing procedures without such deliberation. Conclusions Reasoning that categorisation is a fundamental aspect of risk perception, we argue that patients can be encouraged to develop more nuanced and accurate categorisations of their own risk through their interactions with clinicians. Empirically‐based ethical reflection is required to determine whether and when it is appropriate to provide risk‐reduction procedures to alleviate worry.

Abstract
Women with a hereditary breast cancer predisposition have three management options: screening, chemoprevention (risk-reducing medication) and risk-reducing surgery. However, no randomized trials have addressed the effect of these strategies in mutation carriers. In the general population, randomized trials failed to demonstrate a benefit for screening in premenopausal women. Moreover, although chemoprevention reduces breast cancer incidence in high-risk populations, this benefit is potentially confined to estrogen receptor-positive tumors. Finally, observational studies suggest that prophylactic mastectomy and even prophylactic salpingo-ophorectomy reduces breast cancer risk in BRCA mutation carriers, but there are systematic biases associated with such studies. Therefore, women with a hereditary predisposition for breast cancer should be informed of the three risk-reducing strategies, and that their benefits are not fully understood.

Abstract
Pathogenic mutations in BRCA1 and BRCA2 are associated with high risks of breast and ovarian cancer. However, penetrance estimates for mutation carriers have been found to vary substantially between studies, and the observed differences in risk are consistent with the hypothesis that genetic and environmental factors modify cancer risks for women with these mutations. Direct evidence that this is the case has emerged in the past decade, through large-scale international collaborative efforts. Here, we describe the methodological challenges in the identification and characterisation of these risk-modifying factors, review the latest evidence on genetic and lifestyle/hormonal risk factors that modify breast and ovarian cancer risks for women with BRCA1 and BRCA2 mutations and outline the implications of these findings for cancer risk prediction. We also review the unresolved issues in this area of research and identify strategies of clinical implementation so that women with BRCA1 and BRCA2 mutations are no longer counselled on the basis of 'average' risk estimates.

Abstract
BACKGROUND Risk-reducing salpingo-oophorectomy (RRSO) is the most effective intervention to prevent ovarian cancer (OC). It is only available to high-risk women with >10% lifetime OC risk. This threshold has not been formally tested for cost-effectiveness. OBJECTIVE To specify the OC risk thresholds for RRSO being cost-effective for preventing OC in premenopausal women. METHODS The costs as well as effects of surgical prevention ('RRSO') were compared over a lifetime with 'no RRSO' using a decision analysis model. RRSO was undertaken in premenopausal women >40 years. The model was evaluated at lifetime OC risk levels: 2%, 4%, 5%, 6%, 8% and 10%. Costs and outcomes are discounted at 3.5%. Uncertainty in the model was assessed using both deterministic sensitivity analysis and probabilistic sensitivity analysis (PSA). Outcomes included in the analyses were OC, breast cancer (BC) and additional deaths from coronary heart disease. Total costs and effects were estimated in terms of quality-adjusted life-years (QALYs); incidence of OC and BC; as well as incremental cost-effectiveness ratio (ICER). DATA SOURCES Published literature, Nurses Health Study, British National Formulary, Cancer Research UK, National Institute for Health and Care Excellence guidelines and National Health Service reference costs. The time horizon is lifetime and perspective: payer. RESULTS Premenopausal RRSO is cost-effective at 4% OC risk (life expectancy gained=42.7 days, ICER=£19 536/QALY) with benefits largely driven by reduction in BC risk. RRSO remains cost-effective at >8.2% OC risk without hormone replacement therapy (ICER=£29 071/QALY, life expectancy gained=21.8 days) or 6%if BC risk reduction=0 (ICER=£27 212/QALY, life expectancy gained=35.3 days). Sensitivity analysis indicated results are not impacted much by costs of surgical prevention or treatment of OC/ BC or cardiovascular disease. However, results were sensitive to RRSO utility scores. Additionally, 37%, 61%, 74%, 84%, 96% and 99.5% simulations on PSA are cost-effective for RRSO at the 2%, 4%, 5%, 6%, 8% and 10% levels of OC risk, respectively. CONCLUSIONS Premenopausal RRSO appears to be extremely cost-effective at ≥4% lifetime OC risk, with ≥42.7 days gain in life expectancy if compliance with hormone replacement therapy is high. Current guidelines should be re-evaluated to reduce the RRSO OC risk threshold to benefit a number of at-risk women who presently cannot access risk-reducing surgery.

Abstract
Women with an increased lifetime risk of ovarian cancer are advised to undergo risk-reducing salpingo-oophorectomy (RRSO) to reduce risk of adnexal cancer. We investigated the uptake of RRSO and evaluated the influence of personal medical history of (breast) cancer, risk-reducing mastectomy (RRM) and family history of ovarian and/or breast cancer on the RRSO decision. This single center retrospective observational cohort study was performed in a tertiary multidisciplinary clinic for hereditary cancer of the University Medical Centre Utrecht, The Netherlands. Women ≥35 years old with an estimated lifetime risk of ovarian cancer ≥10%, who had completed childbearing, were eligible for RRSO. Uptake and timing of RRSO were analyzed. Influence of personal medical history and family history on RRSO decision making, were evaluated with logistic regression. The study population consisted of 218 women (45.0% BRCA1 mutation carrier, 28.0% BRCA2 mutation carrier, 27.0% with familial susceptibility) with 87.2% RRSO uptake. The median age at RRSO was 44.5 (range 28-73) years. Of the women undergoing RRSO, 78.3% needed ≤3 consultations to reach this decision. Multivariable analysis showed a significant difference in RRSO uptake for women with a history of RRM [OR 3.66 95% CI (1.12-11.98)], but no significant difference in women with a history of breast cancer [OR 1.38 95% CI (0.50-3.79)], nor with a family history of ovarian and/or breast cancer [OR 1.10 95% CI (0.44-2.76)]. We conclude that RRSO counseling, without the alternative of screening, is effective. The uptake is increased in women with a history of RRM.

Abstract
The purpose of this study was to estimate the influence of adjuvant radiotherapy for primary breast cancer (BC) on the risk of contralateral BC (CBC) in BRCA1 or BRCA2(BRCA1/2) mutation carriers, with special attention to patients irradiated at age younger than 40 years. Additionally, tendencies in locoregional treatments and rates of contralateral risk-reducing mastectomy over time were explored. In this retrospective cohort study, 691 BRCA1/2-associated BC patients treated between 1980 and 2013 were followed from diagnosis until CBC or censoring event including ipsilateral BC recurrence, distant metastasis, contralateral risk-reducing mastectomy, other invasive cancer diagnosis, death, or loss to follow up. Hazard ratios (HR) for CBC associated with radiotherapy were estimated using Cox regression. Median follow-up time was 8.6 years [range 0.3–34.3 years]. No association between radiotherapy for primary BC and risk of CBC was found, neither in the total population (HR 0.82, 95 % CI 0.45–1.49) nor in the subgroup of patients younger than 40 years at primary diagnosis (HR 1.36, 95 % CI 0.60–3.09). During follow-up, the number of patients at risk decreased substantially since a large proportion of patients were censored after contralateral risk-reducing mastectomy or BC recurrence. Over the years, increasing preference for mastectomy without radiotherapy compared to breast-conserving surgery with radiotherapy was found ranging from less than 30 % in 1995 to almost 50 % after 2010. The rate of contralateral risk-reducing mastectomy increased over the years from less than 40 % in 1995 to more than 60 % after 2010. In this cohort of BRCA1/2-associated BC patients, no association between radiotherapy for primary BC and risk of CBC was observed in the total group, nor in the patients irradiated before the age of 40 years. The number of patients at risk after 10 and 15 years of follow-up, however, was too small to definitively exclude harmful effects of adjuvant radiotherapy.

Abstract
OBJECTIVE Risk-reducing salpingo-oophorectomy (RRSO) is the only effective surgical strategy to reduce the increased risk of epithelial ovarian cancer in BRCA1/2 mutation carriers. Given the long-term health consequences of premature surgical menopause, we need insight in uptake and timing of RRSO to guide us in improving healthcare. METHODS A single-center retrospective cohort study of BRCA1/2 mutation carriers diagnosed and counseled at the multidisciplinary Family Cancer Clinic of the Radboud university medical center in Nijmegen, The Netherlands, between 1999 and 2014. Descriptive statistics were used to analyze uptake and timing of RRSO. RESULTS Data of 580 BRCA1/2 were analyzed. The uptake of RRSO among mutation carriers who are currently above the upper limit of the recommended age for RRSO, is 98.5% and 97.5% for BRCA1 and BRCA2 mutation carriers, respectively. The vast majority undergoes RRSO ≤40 (BRCA1) or ≤45 (BRCA2) years of age, provided that mutation status is known by that age: 90.8% and 97.3% of BRCA1 and BRCA2 mutation carriers, respectively. CONCLUSIONS The uptake of RRSO among BRCA1/2 mutation carriers who were counseled at our Family Cancer Clinic is extremely high. High uptake might be largely attributed to the directive and uniform way of counseling by professionals at our Family Cancer Clinic. Given the fact that RRSO is often undergone at premenopausal age in our population, future research should focus on minimizing long-term health consequences of premature surgical menopause either by optimization of hormone replacement therapy or by investigating alternative strategies to RRSO.

RANK ligand as a potential target for breast cancer prevention in BRCA1-mutation carriers. Nat Med 2016; 22:933-9.

Abstract
Individuals who have mutations in the breast-cancer-susceptibility gene BRCA1 (hereafter referred to as BRCA1-mutation carriers) frequently undergo prophylactic mastectomy to minimize their risk of breast cancer. The identification of an effective prevention therapy therefore remains a 'holy grail' for the field. Precancerous BRCA1(mut/+) tissue harbors an aberrant population of luminal progenitor cells, and deregulated progesterone signaling has been implicated in BRCA1-associated oncogenesis. Coupled with the findings that tumor necrosis factor superfamily member 11 (TNFSF11; also known as RANKL) is a key paracrine effector of progesterone signaling and that RANKL and its receptor TNFRSF11A (also known as RANK) contribute to mammary tumorigenesis, we investigated a role for this pathway in the pre-neoplastic phase of BRCA1-mutation carriers. We identified two subsets of luminal progenitors (RANK(+) and RANK(-)) in histologically normal tissue of BRCA1-mutation carriers and showed that RANK(+) cells are highly proliferative, have grossly aberrant DNA repair and bear a molecular signature similar to that of basal-like breast cancer. These data suggest that RANK(+) and not RANK(-) progenitors are a key target population in these women. Inhibition of RANKL signaling by treatment with denosumab in three-dimensional breast organoids derived from pre-neoplastic BRCA1(mut/+) tissue attenuated progesterone-induced proliferation. Notably, proliferation was markedly reduced in breast biopsies from BRCA1-mutation carriers who were treated with denosumab. Furthermore, inhibition of RANKL in a Brca1-deficient mouse model substantially curtailed mammary tumorigenesis. Taken together, these findings identify a targetable pathway in a putative cell-of-origin population in BRCA1-mutation carriers and implicate RANKL blockade as a promising strategy in the prevention of breast cancer.

Abstract
Female BRCA1/BRCA2 mutation carriers are at substantially increased risk for developing breast and/or ovarian cancer, and are offered enhanced surveillance including screening from a young age and risk-reducing surgery (RRS)-mastectomy (RRM) and/or salpingo-oophorectomy (RRSO). While there are established guidelines for early detection of breast cancer in high-risk women who have not undergone RRM, there are less developed guidelines after RRM. We evaluated the schemes offered before and after RRS in internationally diverse high-risk clinics. An e-mailed survey was distributed to high-risk clinics affiliated with CIMBA. Overall, 22 centers from 16 countries responded. Pre RRS surveillance schemes overwhelmingly included breast imaging (primarily MRI) from 18 to 30 years and clinical breast exam (CBE) at 6-12 month intervals. For ovarian cancer, all but 6 centers offered semiannual/annual gynecological exam, transvaginal ultrasound, and CA 125 measurements. Post RRM, most centers offered only annual CBE while 4 centers offered annual MRI, primarily for substantial residual breast tissue. After RRSO only 4 centers offered specific gynecological surveillance. Existing guidelines for breast/ovarian cancer detection in BRCA carriers are being applied pre RRS but are not globally harmonized, and most centers offer no specific surveillance post RRS. From this comprehensive multinational study it is clear that evidence-based, long-term prospective data on the most effective scheme for BRCA carriers post RRS is needed.

Abstract
BACKGROUND The US Preventative Service Task Force recommends that physicians perform a genetic risk assessment to identify women at risk for BRCA1/2 mutations associated with hereditary breast and ovarian cancer (HBOC) syndrome. However, outcomes data after a diagnosis of HBOC syndrome especially in diverse populations, are minimal. Here we asked if genetic screening of high-risk underserved women identified in the mammogram population reduces cancer incidence. METHODS We evaluated 61,924 underserved women at screening mammography for family histories suggestive of HBOC syndrome over the course of 21 months. Data were collected retrospectively from patients at two safety net hospitals through chart review. A computer model was used to calculate the long-term effect of this screening on cancer incidence by assessing both the mutation detection rate and the completion of prophylactic surgeries in BRCA1/2 mutation carriers. FINDINGS We identified 20 of the 85 (23.5%) expected BRCA1/2 mutation carriers in the underserved population. The frequencies of prophylactic mastectomies and oophorectomies in the mutation carriers were 25% and 40%, respectively. Using these data, our model predicted only an 8.8% reduction in both breast and ovarian cancer in the underserved patients. This contrasts with a 57% reduction in breast cancer and 51% reduction in ovarian cancer in an insured reference population. Our data indicate that underserved patients with HBOC syndrome are difficult to identify and when identified are limited in their ability to adhere to NCCN guidelines for cancer prevention. INTERPRETATION Screening for women at risk for HBOC syndrome in mammogram populations will only prevent cancers if we can increase compliance with management guidelines. This study provides prototypic baseline data for step-wise analysis of the efficacy of the use of family history analysis in the mammography setting for detection and management of HBOC syndrome.

Abstract
Background Risk-reducing salpingo-oophorectomy (RRSO) around the age of 40 is currently recommended to BRCA1/2 mutation carriers. This procedure decreases the elevated ovarian cancer risk by 80–96 % but it initiates premature menopause as well. The latter is associated with short-term and long-term morbidity, potentially affecting quality of life (QoL). Based on recent insights into the Fallopian tube as possible site of origin of serous ovarian carcinomas, an alternative preventive strategy has been put forward: early risk-reducing salpingectomy (RRS) and delayed oophorectomy (RRO). However, efficacy and safety of this alternative strategy have to be investigated. Methods A multicentre non-randomised trial in 11 Dutch centres for hereditary cancer will be conducted. Eligible patients are premenopausal BRCA1/2 mutation carriers after completing childbearing without (a history of) ovarian carcinoma. Participants choose between standard RRSO at age 35–40 (BRCA1) or 40–45 (BRCA2) and the alternative strategy (RRS upon completion of childbearing and RRO at age 40–45 (BRCA1) or 45–50 (BRCA2)). Women who opt for RRS but do not want to postpone RRO beyond the currently recommended age are included as well. Primary outcome measure is menopause-related QoL. Secondary outcome measures are ovarian/breast cancer incidence, surgery-related morbidity, histopathology, cardiovascular risk factors and diseases, and cost-effectiveness. Mixed model data analysis will be performed. Discussion The exact role of the Fallopian tube in ovarian carcinogenesis is still unclear. It is not expected that further fundamental research will elucidate this role in the near future. Therefore, this clinical trial is essential to investigate RRS with delayed RRO as alternative risk-reducing strategy in order to improve QoL. Trial registration ClinicalTrials.gov (NCT02321228)

Abstract
Zusammenfassung
Für das familiäre Mamma- und Ovarialkarzinom ist seit der Entdeckung der beiden Hochrisikogene BRCA1 und BRCA2 in den 1990er-Jahren die genetische Testung und die damit einhergehende individuelle Risikobestimmung möglich. In den zurückliegenden 20 Jahren waren im Rahmen der Betreuung von BRCA-Mutationsträgerinnen und ihren Familien die Bestimmung der Inzidenz und des Phänotyps der Karzinome sowie der Nachweis der Effizienz von prophylaktischen Operationen, intensivierter Brustkrebsfrüherkennung und zielgerichteter Therapieverfahren möglich. Dies versetzt uns heute in die Lage, bei Ratsuchenden individuelle Risikokalkulationen durchzuführen und sie im Rahmen nicht direktiver Beratungsgespräche auf dem Weg zu einer informierten und präferenzsensiblen Entscheidung in Bezug auf die Inanspruchnahme risikoadaptierter Präventionsmaßnahmen zu begleiten. Aktuell und zukünftig gilt es die Herausforderungen z. B. im Zusammenhang mit der Zulassung des ersten PARP-Inhibitors sowie mit der Entdeckung neuer Risikogene zu bewältigten. Schwerpunkt dieses Artikels ist der Nachweis, dass v. a. Frauen mit Mutationen in den Hochrisikogenen BRCA1/2 von operativen Maßnahmen profitieren.

Abstract
Given the greatly elevated risks of contralateral breast cancer (CBC) observed in breast cancer patients who carry mutation in BRCA1 or BRCA2, the present meta-analysis was addressed to determine whether adjuvant tamoxifen treatment for breast cancer is associated with reduced CBC risk for these patients. We searched the database of PubMed for eligible studies about the effectiveness of tamoxifen on CBC risk among BRCA1/2 mutation carriers, and we calculated the pooled relative risks (RRs) for CBC risk along with 95 % confidence intervals (CIs). Fixed- or random-effects model was conducted according to study heterogeneity. Four non-overlapping studies met the inclusion criteria for the meta-analysis. Tamoxifen was found to be significantly associated with reduced risk of CBC among BRCA1/2 mutation carriers (summary RR = 0.56, 95 % CI = 0.41-0.76). Similar findings were observed in BRCA1 mutation carriers (summary RR = 0.47, 95 % CI = 0.37-0.60) and BRCA2 mutation carriers (summary RR = 0.39, 95 % CI = 0.28-0.54), respectively. In conclusion, tamoxifen significantly reduces the incidence of CBC among BRCA1/2 mutation carriers with primary unilateral breast cancer. It can reasonably be offered to breast cancer patients with BRCA1 or BRCA2 mutation for the prevention of CBC. Further studies are required to get a more precise estimation of the benefits and harms of tamoxifen in these patients.
