RESUMO

PURPOSE: Hereditary breast and ovarian cancer has long been established to affect a considerable number of patients and their families. By identifying those at risk ideally before they have been diagnosed with breast and/or ovarian cancer, access to preventive measures, intensified screening and special therapeutic options can be obtained, and thus, prognosis can be altered beneficially. Therefore, a standardized screening and counseling process has been established in Germany under the aegis of the German Consortium for Hereditary Breast and Ovarian Cancer (GC-HBOC). As one of these specialized clinics, the HBOC-Center at Charité offers genetic counseling as well as genetic analysis based on the GC-HBOC standards. This analysis aims first at depicting this process from screening through counseling to genetic analysis as well as the patient collective and second at correlating the results of genetic analysis performed. Thus, real-world data from an HBOC-Center with a substantial patient collective and a high frequency of pathogenic variants in various genes shall be presented. METHODS: The data of 2531 people having been counseled at the HBOC-Center at Charité in 2016 and 2017 were analyzed in terms of patient and family history as well as pathogenic variants detected during genetic analysis with the TruRisk® gene panel when genetic analysis was conducted. This standardized analysis is compiled and regularly adjusted by the GC-HBOC. The following genes were included at time of research: BRCA1, BRCA2, ATM, CDH1, CHEK2, PALB2, RAD51C, RAD51D, NBN, and TP53. RESULTS: Genetic analysis was conducted in 59.8% of all cases meeting the criteria for genetic analysis and 286 pathogenic variants were detected among 278 (30.3%) counselees tested using the TruRisk® gene panel. These were primarily found in the genes BRCA1 (44.8%) and BRCA2 (28.3%) but also in CHEK2 (12.2%), ATM (5.6%) and PALB2 (3.5%). The highest prevalence of pathogenic variants was seen among the families with both ovarian and breast cancer (50.5%), followed by families with ovarian cancer only (43.2%) and families with breast cancer only (35.6%)-these differences are statistically significant (p < 0.001). Considering breast cancer subtypes, the highest rate of pathogenic variants was detected among patients with triple-negative breast cancer (40.7%) and among patients who had had been diagnosed with triple-negative breast cancer before the age of 40 (53.4%)-both observations proved to be statistically significant (p = 0.003 and p = 0.001). CONCLUSION: Genetic counseling and analysis provide the foundation in the prevention and therapy of hereditary breast and ovarian cancer. The rate of pathogenic variants detected is associated with family history as well as breast cancer subtype and age at diagnosis, and can reach considerable dimensions. Therefore, a standardized process of identification, genetic counseling and genetic analysis deems mandatory.

RESUMO

OBJECTIVES: Risk-reducing mastectomy (RRM) is one of key prevention strategies in female carriers of germline BRCA pathogenic/likely pathogenic variants (PV/LPV). We retrospectively investigated the rate, timing and longitudinal trends of bilateral RRM uptake and the incidence and types of cancers among unaffected BRCA carriers who underwent genetic counseling at the Institute of Oncology Ljubljana in Slovenia. MATERIALS AND METHODS: Female BRCA carriers without personal history of cancer were included in the study. Clinical data on PV/LPV type, date of RRM, type of reconstructive procedure, occult carcinoma and histopathology results was collected and analyzed. RESULTS: Of the 346 unaffected BRCA carriers (median age 43 years, 70% BRCA1, 30% BRCA2, median follow-up 46 months) who underwent genetic testing between October 1999 and December 2019, 25.1% had a RRM (range 35-50 years, median age at surgery 38 years). A significant difference in time to prophylactic surgery between women undergoing RRM only vs. women undergoing RRM combined with risk-reducing salpingo-oophorectomy was observed (22.6 vs 8.7 months, p = 0.0009). We observed an upward trend in the annual uptake in line with the previously observed Angelina Jolie effect. In 5.7% of cases, occult breast cancer was detected. No women developed breast cancer after RRM. Women who did not opt for surgical prevention developed BRCA1/2-related cancers (9.3%). CONCLUSION: The uptake of RRM among unaffected BRCA carriers is 25.1% and is similar to our neighboring countries. No women developed breast cancer after RRM while women who did not opt for surgical prevention developed BRCA1/2 related cancers in 9.3% of cases. The reported data may provide meaningful aid for carriers when deciding on an optimal prevention strategy.

RESUMO

BACKGROUND: We studied the extent of BRCA1/2 genetic testing to help select the surgical approach for patients with breast cancer in Japan remains unclear. PATIENTS AND METHODS: The study subjects were female patients with primary unilateral invasive breast cancer considered as candidates for breast-conserving surgery who underwent preoperative BRCA1/2 genetic testing. A retrospective analysis was performed on the results of BRCA1/2 genetic testing and surgical method selection using national registration data from the Japanese Hereditary Breast and Ovarian Cancer Syndrome Consortium. RESULTS: Our study included 318 female patients. Among these patients, 23.7% of patients with BRCA1/2 mutations and 61.8% of patients without these variants underwent breast-conserving surgery (P < .01). Among the patients with BRCA1/2 mutations, those who chose breast-conserving surgery tended not to undergo risk-reducing salpingo-oophorectomy (P < .05). Among the patients with BRCA1/2 mutations who underwent mastectomy for the affected side, 31.8% received contralateral risk-reducing mastectomy. Patients diagnosed with breast cancer under the age of 50 years were more likely to have contralateral risk-reducing mastectomy than patients over the age 50 years (P < .05). CONCLUSIONS: Patients with BRCA1/2 mutations tend to choose mastectomy. However, it is speculated that the final surgical method selection is made in consideration of not only the test results but also with careful consideration of the patient, taking into account other factors including individual values for risk-reducing surgeries and the age of breast cancer onset.

RESUMO

Objectives To review non-surgical prevention strategies in women with hereditary breast and ovarian cancer syndromes. Content Women with a gBRCA1 or 2 mutations face a high cumulative breast and ovarian cancer risk. While bilateral mastectomy (PBM) and bilateral salpingo-oophrectomy (PBSO) profoundly reduce the respective cancer risks, they are also associated with considerable side effects. There is therefore an urgent need for alternative and non-surgical risk reduction options. Tamoxifen and aromatase inhibitors have both been evaluated in secondary prevention, but their benefit in primary prevention is currently unknown in BRCA mutation carriers. In addition, their use is compromised by their side effect profile which makes them less appealing for a use in chemoprevention. Summary and outlook Denosumab is a well-tolerated osteoprotective drug, which has been demonstrated to have a potential preventive effect particularly in BRCA1-deficient models in vitro. The prospectively randomized double-blind BRCA-P trial is currently investigating the preventative effect of denosumab in healthy BRCA1 germ line mutation carriers.

RESUMO

Current guidelines recommend BRCA1 and BRCA2 genetic testing for individuals with a personal or family history of certain cancers. Three BRCA1/2 founder variants - 185delAG (c.68_69delAG), 5382insC (c.5266dupC), and 6174delT (c.5946delT) - are common in the Ashkenazi Jewish population. We characterized a cohort of more than 2,800 research participants in the 23andMe database who carry one or more of the three Ashkenazi Jewish founder variants, evaluating two characteristics that are typically used to recommend individuals for BRCA testing: self-reported Jewish ancestry and family history of breast, ovarian, prostate, or pancreatic cancer. Of the 1,967 carriers who provided self-reported ancestry information, 21% did not self-report Jewish ancestry; of these individuals, more than half (62%) do have detectable Ashkenazi Jewish genetic ancestry. In addition, of the 343 carriers who provided both ancestry and family history information, 44% did not have a first-degree family history of a BRCA-related cancer and, in the absence of a personal history of cancer, would therefore be unlikely to qualify for clinical genetic testing. These findings may help inform the discussion around broader access to BRCA genetic testing.

RESUMO

PURPOSE: Identification of inherited breast cancer may guide cancer risk management. We sought to compare risk management practices across women with inherited breast cancer genes. METHODS: Females with a pathogenic/likely pathogenic (P/LP) variant in BRCA1/2, PALB2, CHEK2, and/or ATM were surveyed about cancer risk management. Comparisons were made across genes. RESULTS: The 235 participants with P/LP variants (186 BRCA1/2, 28 PALB2, 15 CHEK2, and 6 ATM) had a median age of 54 and 61% had a prior breast cancer diagnosis. For women with P/LP variants in BRCA1/2, PALB2, and ATM/CHEK2, bilateral mastectomy (BM) rates were 79%, 61%, and 52%, and bilateral oophorectomy (BO) rates were 89%, 30%, and 37%, respectively. Among women with P/LP variants in PALB2 and ATM/CHEK2, 27% of those who had a BO had a family history of ovarian cancer. Contralateral mastectomy rates for women with P/LP variants in PALB2 and ATM/CHEK2 with unilateral breast cancer were 60% and 58%, and BM rates for those without breast cancer were 57% and 29%, respectively. CONCLUSION: These findings suggest high rates of both contralateral mastectomies among those with unilateral breast cancer and BM among those without a breast cancer diagnosis across women with P/LP variants in high and moderate penetrance breast cancer genes. BO was also often utilized for risk reduction across these women. These findings suggest potential overtreatment through risk-reducing surgery, and highlight the importance of promoting guideline-adherent, risk-appropriate care.

RESUMO

Inherited mutations in BRCA1 and BRCA2 genes increase the risk of development of cancer in organs especially in breast and ovary. Prevention and screening in BRCA mutation carriers are of high importance. Prophylactic surgeries are possible but are still insufficiently performed because they require surgical procedures in healthy patients. Guidelines for the management of BRCA mutations carriers must absolutely be part of the standard practice of all those involved in the management of these patients to increase the impact of the implementation of these preventive measures. There is no screening recommended for ovarian cancer. A risk-reducing bilateral salpingo-oophorectomy should be performed from age 35 to 40 years for BRCA1 mutation carriers and 40 to 45 years for BRCA2 mutation carriers. A screening for breast cancer should be performed annually from 30 years old by breast MRI and mammography. A risk-reducing bilateral mastectomy is recommended with nipple sparing mastectomy and immediate breast reconstruction from 30 years and before 40 years. A multidisciplinary care must be implemented for these patients with an important psychological support.

RESUMO

Despite their ubiquitous expression, the inheritance of monoallelic germline mutations in breast cancer susceptibility gene type 1 or 2 (BRCA1/2) poses tissue-specific variations in cancer risks and primarily associate with familial breast and ovarian cancers. The molecular basis of this tissue-specific tumor incidence remains unknown and intriguing to cancer researchers. A plethora of recent reports support the idea that several nongenetic factors present in the tissue microenvironment could induce tumors in the mutant BRCA1/2 background. This Opinion article summarizes the recent advances on tissue-specific carcinogens and their complex crosstalk with the compromised DNA repair machinery of BRCA1/2-mutant cells. Finally, we present our perspective on the therapeutic and chemopreventive interpretations of these developments.

RESUMO

Social media is increasingly being used as an information source and tool for individuals and organizations to share resources and engage in conversations about health topics. Because the public tends to learn about health topics and genetics from online social media sources, it is imperative to understand the amount, type, and quality of information being shared. We performed a retrospective analysis of tweets related to hereditary breast and ovarian cancer (HBOC) and Lynch syndrome (LS) between January 1, 2017 and December 31, 2017. A total of 63,770 tweets were included in our dataset. The majority were retweets (59.9%) and users came from 744 different cities. Most tweets were considered "informational" (51.4%) and were designed to provide resources to the public. Online communities (25%), organizations (20%), and providers or researchers (15%) were among the most common contributors. Our results demonstrated that conversations were primarily focused on information and resource sharing, along with individuals discussing their personal stories and testimonials about their experiences with these HBOC and LS. Future studies could consider ways to harness Twitter to help tailor and deliver health communication campaigns and education interventions to improve the public's understanding of these complex topics.

RESUMO

OBJECTIVE: National guidelines provide breast cancer (BC) risk management recommendations based on estimated lifetime risk. Despite this specificity, it is unclear if women's risk management intentions are or are not guideline concordant. To address this knowledge gap, women at varying risk levels reported intentions for risk-reducing behaviors. Factors associated with intentions, informed by the Health Beliefs Model, were also studied. METHODS: Women with elevated BC risk (N = 103) were studied and categorized by risk level: moderate (15%-20%), high (greater than or equal to 20%), or very high (BRCA1/2 positive). Participants self-reported BC susceptibility, self-efficacy, and benefits, barriers, and intentions for risk-reducing mastectomy (RRM), risk-reducing salpingo-oophorectomy (RRSO), chemoprevention, improving diet or physical activity, and reducing alcohol use. RESULTS: Groups significantly differed in RRSO intentions (P < .01); BRCA1/2 positive women had greater intentions for RRSO. Groups did not differ in intentions for RRM, chemoprevention, or lifestyle changes (Ps > .28). In hierarchical linear regression models examining Health Belief Model (HBM) factors, perceived susceptibility was associated with intentions for RRM (ß = .169, P = .08). Perceived benefits was associated with intentions for RRM (ß = .237, P = .02) and chemoprevention (ß = .388, P < .01). Self-efficacy was associated with intentions for physical activity (ß = .286, P < .01). CONCLUSIONS: Consistent with guidelines, BRCA1/2 positive women reported greater intentions for RRSO, and risk groups did not differ in intentions for lifestyle changes. Notably, women's intentions for RRM and chemoprevention were guideline discordant; groups did not differ in intentions for these behaviors. Accounting for the effects of risk group, modifiable health beliefs were also associated with risk management intentions; these may represent targets for decision support interventions.

RESUMO

BRCA1/BRCA2 genes were discovered in early 1990s and clinical testing for these has been available since the mid-1990s. National Institute of Health and Care Excellence (NICE) and other international guidelines recommend genetic-testing at a ~10% probability threshold of carrying a BRCA-mutation. A detailed three generation family-history (FH) of cancer is used within complex mathematical models (e.g. BOADICEA, BRCAPRO, Manchester-Scoring-System) or through standardized clinical-criteria to identify individuals who fulfil this probability threshold and can be offered genetic-testing. Identification of unaffected carriers is important given the high risk of cancer in these women and the effective options available for clinical management which can reduce cancer risk, improve outcomes and minimise burden of disease.

RESUMO

Following the identification in a proband of a germline BRCA1/BRCA2 mutation in hereditary breast-ovarian cancer (HBOC) or a DNA mismatch repair gene mutation in Lynch syndrome (LS) he or she will be asked to inform at-risk family members about the option for presymptomatic DNA testing. However, in clinical practice multiple factors may complicate the process of information sharing. We critically evaluated studies on the uptake of presymptomatic genetic testing in both syndromes. A search of relevant MeSH terms and key words in PubMed, Embase and PsycINFO yielded 795 articles published between 2001 and 2017. Thirty of these publications included outcome measures relevant for the current study. Based on information provided by the proband (15 studies) the uptake of presymptomatic genetic testing ranged from 15 to 57% in HBOC, while one study in LS kindreds reported an uptake of 70%. Based on information provided by genetics centres (the remaining 15 studies) the uptake ranged from 21 to 44% in HBOC and from 41 to 94% in LS. However, when genetics centres contacted relatives directly a substantial number of additional family members could be tested. Proband-mediated provision of information to at-risk relatives is a standard procedure in hereditary breast-ovarian cancer and Lynch syndrome. However, the resulting uptake of presymptomatic testing is disappointing-an issue that is now urgent due to the increased use of genetic testing in clinical oncology. We propose that additional strategies should be introduced including the geneticist directly contacting relatives. The outcomes of these strategies should be carefully monitored and evaluated.

RESUMO

Carriers of genetic mutations that predispose to cancer syndromes are often faced with complex decisions. For women with hereditary breast and ovarian cancer in particular, the decision to undergo risk-reducing mastectomy or bilateral salpingo-oophorectomy is burdensome from a physical and psychological perspective. Although risk-reducing surgery is the most effective preventative measure in reducing a genetic mutation carrier's risk of breast or ovarian cancer, the success of these procedures requires a multidisciplinary approach that centers on careful counseling regarding the risks and benefits of risk-reducing surgery. The physical and psychological distress associated with risk-reducing surgery often makes a combined surgical approach attractive to some patients. In this review, we present the evidence surrounding the comprehensive surgical care of women with hereditary breast and ovarian cancer syndromes and evaluate the perioperative factors that influence surgical management.

RESUMO

OBJECTIVE: To assess the short- and long-term effects of mindfulness-based stress reduction (MBSR) on the resulting quality of life, sexual functioning, and sexual distress after risk-reducing salpingo-oophorectomy (RRSO). DESIGN: Randomised controlled trial. SETTING: A specialised family cancer clinic of the university medical center Groningen. POPULATION: Sixty-six women carriers of the BRCA1/2 mutation who developed at least two moderate-to-severe menopausal symptoms after RRSO. METHODS: Women were randomised to an 8-week MBSR training programme or to care as usual (CAU). MAIN OUTCOME MEASURES: Change in the Menopause-Specific Quality of Life Questionnaire (MENQOL), the Female Sexual Function Index, and the Female Sexual Distress Scale, administered from baseline at 3, 6, and 12 months. Linear mixed modelling was applied to compare the effect of MBSR with CAU over time. RESULTS: At 3 and 12 months, there were statistically significant improvements in the MENQOL for the MBSR group compared with the CAU group (both P = 0.04). At 3 months, the mean MENQOL scores were 3.5 (95% confidence interval, 95% CI 3.0-3.9) and 3.8 (95% CI 3.3-4.2) for the MBSR and CAU groups, respectively; at 12 months, the corresponding values were 3.6 (95% CI 3.1-4.0) and 3.9 (95% CI 3.5-4.4). No significant differences were found between the MBSR and CAU groups in the other scores. CONCLUSION: Mindfulness-based stress reduction was effective at improving quality of life in the short- and long-term for patients with menopausal symptoms after RRSO; however, it was not associated with an improvement in sexual functioning or distress. TWEETABLE ABSTRACT: Mindfulness improves menopause-related quality of life in women after risk-reducing salpingo-oophorectomy.

RESUMO

OBJECTIVE: To assess the usefulness of risk reduction salpingo-oophorectomy in cases with mutation of the BRCA1 gene in Colombia. MATERIAL AND METHODS: Cost-effectiveness analysis in which three processes are incorporated: a. Patients with screening tests for breast and ovarian cancer. b. Risk reduction surgery in the fallopian tubes and ovaries c. Reductive surgery in the fallopian tubes and ovaries with bilateral mastectomy. The outcome is evaluated as the gain in years of survival. RESULTS: The cohort with risk reduction surgery in the fallopian tubes and ovaries and bilateral mastectomy is the one with the highest gain with 13 years, while the risk reduction surgery in the fallopian tubes and ovaries gain 4.95 years with respect to the follow-up group. CONCLUSIONS: The three options evaluated are acceptable, but of them the one with the greatest gain in survival is the combination of risk-reducing surgery in the fallopian tubes and ovaries with bilateral mastectomy.

RESUMO

The hereditary breast and ovarian cancer (HBOC) registration system of Japan was established by the Japanese HBOC Consortium. The first trial was registered in 2015 in four institutions to which some registration committee members belonged. We analyzed the information of 830 Japanese pedigrees, who underwent BRCA1/2 genetic testing, including mutation carriers with BRCA1 (N = 127) and BRCA2 (N = 115), and their families. The mutation-positive rate was 19.7%. Variants of uncertain significance were found in 6.5% of all individuals subjected to genetic testing for BRCA1/2. Compared to the United States, Japan had a higher mutation-positive rate in most categories, except for the groups with male breast cancer. Among the intrinsic subtypes of BRCA1-associated breast cancers, 75.8% were triple-negative. The incidence rate of contralateral breast cancer in BRCA1/2 mutation carriers was 0.99%/year. Among 240 mutation carriers, 26 and 62 patients underwent risk-reducing mastectomy (RRM) and risk-reducing salpingo-oophorectomy (RRSO), respectively; the respective frequencies of occult cancer were 7.1 and 3.2%. Metachronous breast cancer after RRM or peritoneal cancer after RRSO was not observed during the follow-up period. The nationwide registration system began last year and the system enables follow-up analysis in Japan.

RESUMO

Women carrying germline mutations in BRCA1 or BRCA2 have significantly increased lifetime risks of breast and tubo-ovarian cancer. To manage the breast cancer risk women may elect to have breast screening by MRI/mammogram from age 30, to take risk-reducing medication, or to have a prophylactic bilateral mastectomy. To manage the tubo-ovarian cancer risk, the only effective strategy is to have a bilateral salpingo-oophorectomy, recommended by age 40 (BRCA1) or 'around' age 40 (BRCA2). Early studies suggested that uptake of these cancer risk-reducing strategies was low. More recent studies have revealed higher rates of uptake, however it is unclear whether uptake is genuinely improving or whether the higher uptake rates reflect changes in the populations studied. In this study we surveyed 193 BRCA1/2 mutation carriers in the state of Tasmania to determine the uptake of cancer risk-reducing strategies and what factors might influence women's decisions in relation to both gynaecological and breast surgery. We observed that uptake of risk management strategies varied depending on the strength of the recommendation in the national guidelines. Uptake rates were > 90% for strategies which are strongly recommended, such as breast screening by MRI/mammogram and bilateral salpingo-oophorectomy, and were unaffected by demographic factors such as socio-economic disadvantage and educational achievement. Uptake rates were much lower for strategies which are presented in the guidelines as options for consideration and where patient choice and shared decision making are encouraged, such as prophylactic mastectomy (29%) and chemoprevention (1%) and in the case of prophylactic mastectomy, were influenced by both socio-economic advantage and educational achievement.

RESUMO

The impacts of the Association for Molecular Pathology vs. Myriad Supreme Court decision regarding patenting DNA segments and multi-gene testing on cancer genetic counseling practice have not been well described. We aimed to assess genetic counselors' perceptions of how their genetic testing-related practices for hereditary breast and/or ovarian cancer (HBOC) changed after these events. One-hundred fifty-two genetic counselors from the National Society of Genetic Counselors Cancer Special Interest Group completed an anonymous, online, mixed-methods survey in November 2013. The survey presented four hypothetical patients and asked about changes in testing practice. Across the vignettes, a majority of participants reported specific changes in testing decisions following Association for Molecular Pathology vs. Myriad and availability of multi-gene testing. Ninety-three percent of participants reported changing the types of first- and second-line tests they order for HBOC; the degree of change varied geographically. Qualitative analysis indicated that some counselors have altered the counseling session content, trading depth of information for breadth and spending more time counseling about uncertainty. This study shows that cancer genetic counselors are adapting quickly to genetic testing changes, but with wide variability. Findings suggest future research to elucidate clinicians' and patients' preferences for guidance on the clinical implementation of next-generation sequencing.

RESUMO

OBJECTIVES: Risk-reducing surgeries are a feasible option for mitigating the risk in individuals with inherited susceptibility to cancer, but are the procedures cost-effective in the current health-care system in Germany? This study compared the health-care costs for bilateral risk-reducing mastectomy (BRRM) and risk-reducing (bilateral) salpingo-oophorectomy (RRSO) with cancer treatment costs that could potentially be prevented. PATIENTS AND METHODS: The analysis is based on interdisciplinary consultations with individuals with a high familial risk for breast and ovarian cancer at the University Breast Center for Franconia (Germany) between 2009 and 2013 (370 consultations; 44 patients with BRCA1 mutations and 26 with BRCA2 mutations). Health-care costs for risk-reducing surgeries in BRCA mutation carriers were calculated as reimbursements in the German diagnosis-related groups (DRG) hospital pricing system. These costs for the health-care system were compared with the potential cancer treatment costs that could possibly be prevented by risk-reducing surgeries. RESULTS: Long-term health-care costs can be reduced by risk-reducing surgeries after genetic testing in BRCA mutation carriers. The health-care system in Germany would have saved € 136,295 if BRRM had been performed and € 791,653 if RRSO had been performed before the development of cancer in only 50% of the 70 mutation carriers seen in our center. Moreover, in patients with combined RRSO and BRRM (without breast reconstruction), one further life-year for a 40-year-old BRCA mutation carrier would cost € 2,183. CONCLUSION: Intensive care, including risk-reducing surgeries in BRCA mutation carriers, is cost-effective from the point of view of the health-care system in Germany.

RESUMO

Global media has the power to influence the ways the public engage with health services. On May 14th 2013, Angelina Jolie published an article in the New York Times magazine, outlining her decision to undergo BRCA mutation testing due to a family history of cancer; then proceed with a mastectomy. The article evoked significant interest from the media and the public. During the months that followed, the Familial Cancer Program (FCP) at Genetic Services of Western Australia (GSWA) experienced a significant increase in referrals and enquiries. Resources were overstretched and it became clear we needed to adjust work practices to manage the escalating numbers. New strategies were devised to cope with the influx of enquiries, albeit without the benefit of additional resources. We conducted an audit of referrals to the FCP made between January 2012 and December 2014. This included a comparison of the months prior to and following the New York Times article. The aim of the audit was to quantify the impact of the "Angelina Jolie effect" on referrals to the FCP. Whilst the increased awareness of the role of genetic services in risk assessment and testing for familial breast and ovarian cancer was considered positive, pre-referral risk assessment at the primary health level to evaluate the appropriateness of their patients for referral could have been helpful. Potentially, many inappropriate referrals to FCP may have been avoided with primary health evaluation thus lessening the burden on our service and preventing unnecessary worry in well women who possessed minimal family history or risk factors. It is important to understand the factors driving the uptake of risk reduction activities, particularly if engagement with a genetics service is considered part of that pathway. Continued education about cancer risk due to family history, individual features and awareness surrounding genetic testing criteria, costs and availability is required for both the public and health professionals.
