Hormone Replacement Therapy After Oophorectomy and Breast Cancer Risk Among BRCA1 Mutation Carriers

Bilateral Oophorectomy and All-Cause Mortality in Women With BRCA1 and BRCA2 Sequence Variations

Importance

Preventive bilateral salpingo-oophorectomy is offered to women at high risk of ovarian cancer who carry a pathogenic variant in BRCA1 or BRCA2; however, the association of oophorectomy with all-cause mortality has not been clearly defined.

Objective

To evaluate the association between bilateral oophorectomy and all-cause mortality among women with a BRCA1 or BRCA2 sequence variation.

Design, Setting, and Participants

In this international, longitudinal cohort study of women with BRCA sequence variations, information on bilateral oophorectomy was obtained via biennial questionnaire. Participants were women with a BRCA1 or BRCA2 sequence variation, no prior history of cancer, and at least 1 follow-up questionnaire completed. Women were followed up from age 35 to 75 years for incident cancers and deaths. Cox proportional hazards regression was used to estimate the hazard ratios (HRs) and 95% CIs for all-cause mortality associated with a bilateral oophorectomy (time dependent). Data analysis was performed from January 1 to June 1, 2023.

Exposures

Self-reported bilateral oophorectomy (with or without salpingectomy).

Main Outcomes and Measures

All-cause mortality, breast cancer-specific mortality, and ovarian cancer-specific mortality.

Results

There were 4332 women (mean age, 42.6 years) enrolled in the cohort, of whom 2932 (67.8%) chose to undergo a preventive oophorectomy at a mean (range) age of 45.4 (23.0-77.0) years. After a mean follow-up of 9.0 years, 851 women had developed cancer and 228 had died; 57 died of ovarian or fallopian tube cancer, 58 died of breast cancer, 16 died of peritoneal cancer, and 97 died of other causes. The age-adjusted HR for all-cause mortality associated with oophorectomy was 0.32 (95% CI, 0.24-0.42; P < .001). The age-adjusted HR was 0.28 (95% CI, 0.20-0.38; P < .001) and 0.43 (95% CI, 0.22-0.90; P = .03) for women with BRCA1 and BRCA2 sequence variations, respectively. For women with BRCA1 sequence variations, the estimated cumulative all-cause mortality to age 75 years for women who had an oophorectomy at age 35 years was 25%, compared to 62% for women who did not have an oophorectomy. For women with BRCA2 sequence variations, the estimated cumulative all-cause mortality to age 75 years was 14% for women who had an oophorectomy at age 35 years compared to 28% for women who did not have an oophorectomy.

Conclusions and Relevance

In this cohort study among women with a BRCA1 or BRCA2 sequence variation, oophorectomy was associated with a significant reduction in all-cause mortality.

Development and testing of patient-centered education about hormone replacement therapy for women at high genetic risk of breast and ovarian cancer

OBJECTIVE

In this study, we aimed to develop education to assist BRCA mutation carriers in making informed decisions about HRT in the context of risk-reducing surgery, while simultaneously clarifying their treatment-specific values and reducing decisional conflict.

METHODS

We enrolled premenopausal BRCA mutation carriers ages 19-49 without prior cancer or risk-reducing salpingo-oophorectomy to structured interviews in which they reviewed education about the risks and benefits of HRT. Materials included literature-derived data demonstrating associations between HRT and commonly considered health outcomes (breast cancer, vasomotor symptoms, sexual functioning, cardiovascular disease, osteoporosis, and blood clots). Participants completed the 16-item Decisional Conflict Scale (DCS) before and after education, communicated their preferences by rating and ranking the six outcomes, and provided feedback to inform iterative revisions of the educational content.

RESULTS

25 participants completed interviews. DCS scores decreased significantly from 54.6 to 22.8 following education (p < 0.001); sub-scores for uncertainty (71.7 to 37.3), informed (71.7 to 15.3), values clarity (53.7 to 17.0), effective decision (44.2 to 25.5), and support (35.0 to 17.7) also decreased significantly. Participants ranked cardiovascular disease as the most important outcome to consider, followed by breast cancer, osteoporosis, blood clots, decline in sexual function, and hot flashes. Participants with prior mastectomy (N = 10) ranked breast cancer as the most important outcome 25% of the time, compared to 80% in participants without mastectomy (N = 15).

CONCLUSION

Following education, BRCA mutation carriers had significantly less decisional conflict regarding the choice to use HRT. This pilot study was successful in generating a prototype educational aid for further testing.

Systemic and Local Strategies for Primary Prevention of Breast Cancer

One in eight women will develop breast cancer in the US. For women with moderate (15-20%) to average (12.5%) risk of breast cancer, there are few options available for risk reduction. For high-risk (>20%) women, such as BRCA mutation carriers, primary prevention strategies are limited to evidence-based surgical removal of breasts and/or ovaries and anti-estrogen treatment. Despite their effectiveness in risk reduction, not many high-risk individuals opt for surgical or hormonal interventions due to severe side effects and potentially life-changing outcomes as key deterrents. Thus, better communication about the benefits of existing strategies and the development of new strategies with minimal side effects are needed to offer women adequate risk-reducing interventions. We extensively review and discuss innovative investigational strategies for primary prevention. Most of these investigational strategies are at the pre-clinical stage, but some are already being evaluated in clinical trials and others are expected to lead to first-in-human clinical trials within 5 years. Likely, these strategies would be initially tested in high-risk individuals but may be applicable to lower-risk women, if shown to decrease risk at a similar rate to existing strategies, but with minimal side effects.

Short-term Impact of Hormone Replacement Therapy on Risk of Breast Cancer in BRCA Mutation Carriers: A Nationwide Study in South Korea

PURPOSE

BRCA1/2 mutations are well-known risk factors for breast and ovarian cancers in women. Risk-reducing salpingo-oophorectomy (RRSO) is the standard treatment for preventing ovarian cancer with BRCA mutations. Postmenopausal syndrome (symptoms after RRSO can be alleviated by hormone replacement therapy (HRT); however, the use of HRT in carriers of BRCA mutations has been controversial because of the concern that HRT increases the risk of breast cancer. This study aimed to evaluate the effects of HRT in BRCA mutation carriers who underwent RRSO.

MATERIALS AND METHODS

A total of 151 carriers, who underwent RRSO between 2013 and 2020 after the diagnosis of BRCA1 or BRCA2 mutations were selected and followed up for a median of 3.03 years. Patients were divided into two groups: those who received HRT after RRSO (n=33) and those who did not (n=118). We compared the incidence of breast cancer over time between these two groups.

RESULTS

There was no significant difference in the incidence of breast cancer between women who received HRT and those who did not (p=0.229). Multivariate logistic regression analysis, adjusted for age and parity revealed no significant difference in the risk of breast cancer between these two groups (hazard ratio, 0.312; 95% confidence interval, 0.039 to 2.480; p=0.278).

CONCLUSION

In this study, we found no relationship between post-RRSO HRT and breast cancer in the population with BRCA mutations. Therefore, healthcare providers may consider the alleviation of symptoms of postmenopausal syndrome through HRT in patients who underwent RRSO.

WHAM-A Prospective Study of Weight and Body Composition After Risk-Reducing Bilateral Salpingo-oophorectomy

CONTEXT

Body weight and composition may change over the natural menopause transition. Whether surgical menopause has similar effects, and the impact of hormone replacement therapy (HRT), are unknown. Understanding the metabolic effects of surgical menopause will inform clinical care.

OBJECTIVE

To prospectively measure weight and body composition over 24 months following surgical menopause compared with a similar comparison group who retained their ovaries.

METHODS

Prospective observational study of weight change from baseline to 24 months in 95 premenopausal women at elevated risk of ovarian cancer planning risk-reducing salpingo-oophorectomy (RRSO) and 99 comparators who retained their ovaries. Change in body composition from baseline to 24 months was also assessed by dual-energy x-ray absorptiometry in a subgroup of 54 women who underwent RRSO and 81 comparators who retained their ovaries. In the subgroup, weight, fat mass, lean mass, and abdominal fat measures were compared between groups.

RESULTS

At 24 months both groups had gained weight (RRSO 2760 ± 4860 g vs comparators 1620 ± 4540 g) with no difference between groups (mean difference 730 g; 95% CI 920 g to 2380 g; P = .383). In the body composition subgroup, there was no difference in weight between groups at 24 months (mean difference 944 g; 95% CI -1120 g to 2614 g; P = .431). RRSO women may have gained slightly more abdominal visceral adipose tissue (mean difference 99.0 g; 95% CI 8.8 g to 189.2 g; P = .032) but there were no other differences in body composition. There were also no differences in weight or body composition between HRT users and nonusers at 24 months.

CONCLUSION

24 months after RRSO, there was no difference in body weight compared with women who retained their ovaries. RRSO women gained more abdominal visceral adipose tissue than comparators, but there were no other differences in body composition. Use of HRT following RRSO had no effect on these outcomes.

Concurrent uterine surgery and uptake of hormone therapy in patients undergoing bilateral salpingo-oophorectomy for risk-reducing or therapeutic indications

OBJECTIVE

This study aimed to analyze factors associated with concurrent uterine surgery in patients undergoing bilateral salpingo-oophorectomy (BSO) for risk reducing or therapeutic purposes. Additionally, trends in surgical choice and uptake of post-operative hormone therapy (HT) were examined.

METHODS

A 10-year retrospective study was conducted on patients who underwent risk-reducing or therapeutic BSO at one institution. Multinomial regression analysis of patient and case characteristics was performed evaluating associations with surgery type (BSO, BSO and hysterectomy, or BSO and endometrial sampling). Trends in surgery type and uptake of HT post operatively are described.

RESULTS

Among the study sample of 643 patients, 140 (22%) patients underwent therapeutic BSO for a history of hormone receptor (HR) positive breast cancer, while the remainder underwent risk-reducing BSO due to a pathogenic variant and/or family history. Pathogenic variants included BRCA1 (141, 40%) BRCA2 (173, 49%), and Lynch syndrome genes (15, 4%). Regression analysis revealed significant associations between concurrent hysterectomy and Black race (RR = 3.55, CI = 1.51-8.38, p = 0.004), history of HR positive breast cancer (RR = 1.88, CI = 1.03-3.42, p = 0.04), and surgeon (Surgeon 1, RR = 2.43, CI = 1.36-4.35, p = 0.003). Among eligible patients under age 51, 36% initiated HT. Over the study period, concurrent hysterectomy rates declined while endometrial sampling increased.

CONCLUSIONS

Rates of hysterectomy declined over the study period and slightly more than one-third of eligible patients utilized post-operative HT. Further research on concurrent uterine surgery is needed to establish standardized treatment recommendations in the risk-reducing and therapeutic BSO population. Additionally, education regarding the benefits of postoperative HT in eligible patients is warranted.

Choices for cancer prevention for women with a BRCA1 mutation? a personal view

With widespread testing for susceptibility genes, increasing numbers of women are being identified to carry a mutation in one of many genes which renders them susceptible to cancer. The first gene to be identified (in 1994) was BRCA1 which increases a woman's risk for breast cancer (70%) and ovarian cancer (40%). The prevalence of BRCA1 gene mutations has been studied widely and in many countries, mostly in women affected with cancer. In many settings testing is offered routinely to women with serous ovarian cancer or early-onset or triple-negative breast cancer. It is preferable to identify a mutation in a healthy women prior to the diagnosis of cancer. The basic strategies for prevention include surgical prevention, chemoprevention and screening (early detection). Much progress has been made in the past two decades evaluating the benefits of these three approaches. In this commentary I provide my personal views regarding these various interventions in the context of counselling a newly diagnosed health woman with a BRCA1 mutation.

Effect of Electroacupuncture Versus Cognitive Behavioral Therapy for Perimenopausal Insomnia: Protocol for a Noninferiority Randomized Controlled Trial

BACKGROUND

Perimenopausal insomnia (PMI) has a high global incidence, which is common in middle-aged women and is more severe than nonmenopausal insomnia. Effective treatments with fewer side effects and more consistent repeatable results are needed. Acupuncture, a therapy based on traditional Chinese medicine, is safe and may be effective for PMI. It is widely accepted in Western countries, and evidence supports the use of acupuncture as a main or supplementary therapy. Cognitive behavioral therapy is also used to improve sleep quality. It has structured sessions and has been recommended as a first-line treatment for insomnia (cognitive behavioral therapy for insomnia [CBT-I]) by the American Association of Physicians. However, few randomized controlled trials have been conducted to compare the effectiveness of these 2 therapies. This study will be performed in perimenopausal women with insomnia to determine the efficacy of electroacupuncture (EA) versus CBT-I.

OBJECTIVE

This study aimed to compare the preliminary effectiveness and safety of EA and CBT-I for PMI through a randomized controlled noninferiority study design.

METHODS

This study is designed as an assessor-blinded, noninferiority, randomized controlled trial. A total of 160 eligible participants with PMI will be randomly divided into 2 groups to receive either EA or CBT-I. Participants in the EA group will receive electroacupuncture for 8 weeks. The intervention will be delivered 3 times weekly for a total of 12 sessions and 2 times weekly for the next 4 weeks. Meanwhile, participants in the control group will undergo CBT-I (once a week) for 8 weeks. Treatment will use 7 main acupoints (GV20, DU24, EX-HN3, EX-HN18, EX-CA1, RN6, and RN4) and an extra 4 acupoints based on syndrome differentiation. The primary outcome is the Insomnia Severity Index. The secondary outcome measures are the Pittsburgh Sleep Quality Index; Menopause-Specific Quality of Life; Menopause Rating Scale; Hamilton Depression Scale; Hamilton Anxiety Scale; hot flash score; and the level of estradiol, follicle-stimulating hormone, and luteinizing hormone in serum. Sleep architecture will be assessed using polysomnograms.

RESULTS

Participants are currently being recruited. The first participant was enrolled in January 2023, marking the initiation of the recruitment phase. The recruitment process is expected to continue until January 2025, at which point data collection will commence.

CONCLUSIONS

This trial represents a pioneering effort to investigate the efficacy and safety of EA and CBT-I as interventions for PMI. It is noteworthy that this study is conducted solely within a single center and involves Chinese participants, which is a limitation. Nonetheless, the findings of this study are expected to contribute valuable insights for clinicians engaged in the management of PMI.

Care after premenopausal risk-reducing salpingo-oophorectomy in high-risk women: Scoping review and international consensus recommendations

Women at high inherited risk of ovarian cancer are offered risk-reducing salpingo-oophorectomy (RRSO) from age 35 to 45 years. Although potentially life-saving, RRSO may induce symptoms that negatively affect quality of life and impair long-term health. Clinical care following RRSO is often suboptimal. This scoping review describes how RRSO affects short- and long-term health and provides evidence-based international consensus recommendations for care from preoperative counselling to long-term disease prevention. This includes the efficacy and safety of hormonal and non-hormonal treatments for vasomotor symptoms, sleep disturbance and sexual dysfunction and effective approaches to prevent bone and cardiovascular disease.

Endometrial Cancer Risk Among Germline BRCA1/2 Pathogenic Variant Carriers: Review of Our Current Understanding and Next Steps

PURPOSE

To review the literature exploring endometrial cancer (EC) risk among surgical candidates with germline BRCA1/2 pathogenic variants (PVs) to guide decisions around risk-reducing (rr) hysterectomy in this population.

DESIGN

A comprehensive review was conducted of the current literature that influences clinical practice and informs expert consensus. We present our understanding of EC risk among BRCA1/2 PV carriers, the risk-modifying factors specific to this patient population, and the available research technology that may guide clinical practice in the future. Limitations of the existing literature are outlined.

RESULTS

Patients with BRCA1/2 PVs, those with a personal history of tamoxifen use, those who desire long-term hormone replacement therapy, and/or have an elevated BMI are at higher risk of EC, primarily endometrioid EC and/or uterine papillary serous carcinoma, and may benefit from rr-hysterectomy. Although prescriptive clinical guidelines specific to BRCA1/2 PV carriers could inform decisions around rr-hysterectomy, limitations of the current literature prevent more definitive guidance at this time. A large population-based study of a contemporary cohort of BRCA1/2 PV carriers with lifetime follow-up compared with cancer-gene negative controls would advance this topic and facilitate care decisions.

CONCLUSION

This review validates a potential role for rr-hysterectomy to address EC risk among surgical candidates with BRCA1/2 PVs. Evidence-based clinical guidelines for rr-hysterectomy in BRCA1/2 PV carriers are essential to ensure equitable access to this preventive measure, supporting insurance coverage for patients with either BRCA1 or BRCA2 PVs to pursue rr-hysterectomy. Overall, this review highlights the complexity of EC risk in BRCA1/2 PV carriers and offers a comprehensive framework to shared decision making to inform rr-hysterectomy for BRCA1/2 PV carriers.

Tamoxifen and the risk of breast cancer in women with a BRCA1 or BRCA2 mutation

PURPOSE

Chemoprevention with a selective estrogen receptor modulator (tamoxifen or raloxifene) is a non-surgical option offered to high-risk women to reduce the risk of breast cancer. The evidence for tamoxifen benefit is based on trials conducted among predominantly postmenopausal women from the general population and on studies of contralateral breast cancer in women with a pathogenic variant (mutation hereafter) in BRCA1 or BRCA2. Tamoxifen has not been assessed as a primary prevention agent in women with an inherited BRCA mutation.

METHODS

We conducted a prospective analysis of tamoxifen chemoprevention and the risk of breast cancer in women with a BRCA1 or BRCA2 mutation. Data on tamoxifen (and raloxifene) use was collected by questionnaire and updated biennially. Information on incident cancers was collected by self-report and was confirmed by medical record review. In a matched analysis, we estimated the hazard ratio (HR) and 95% confidence intervals (CI) for developing a first primary breast cancer associated with tamoxifen or raloxifene use, using Cox proportional hazards analysis.

RESULTS

There were 4578 unaffected women in the cohort, of whom 137 reported tamoxifen use (3%), 83 reported raloxifene use (2%) and 12 used both drugs (0.3%). Women who used tamoxifen or raloxifene were matched 1:3 with women who used neither drug on year of birth, country of residence, year of study entry and gene (BRCA1 or BRCA2). We generated 202 matched pairs. After a mean follow-up of 6.8 years, there were 22 incident breast cancers diagnosed among tamoxifen/raloxifene users (10.9% of users) and 71 cases diagnosed among non-users (14.3% of non-users; HR = 0.64; 95% CI 0.40-1.03; P = 0.07).

CONCLUSION

Chemoprevention may be an effective risk-reduction option for BRCA mutation carriers, but further studies with longer follow-up are necessary.

Barriers to hormone therapy following prophylactic bilateral salpingo-oophorectomy in BRCA1/2 mutation carriers

OBJECTIVE

This study aimed to identify barriers to hormone therapy (HT) use among women with BRCA1/2 mutations after prophylactic bilateral salpingo-oophorectomy (BSO).

METHODS

A cross-sectional, electronic survey was conducted of BRCA1/2 mutation carriers at Women and Infants Hospital, Yale Medical Center, Hartford Healthcare, and Maine Medical Center. This study was a subanalysis of a subset of female BRCA1/2 mutation carriers who had undergone a prophylactic BSO. Data were analyzed using the Fisher's exact test or t test.

RESULTS

We performed a subanalysis of 60 BRCA mutation carriers who underwent a prophylactic BSO. Only 24 women (40%) reported ever using HT. HT use was higher in women who underwent their prophylactic BSO at age younger than 45 years (51% vs. 25%, P = 0.06). Among all women who had a prophylactic BSO, the majority (73%) reported that a provider talked to them about using HT. Two thirds reported having seen contradictory information in the media about long-term consequences of HT. Seventy percent listed their provider as the primary influence in their decision to start HT. The most common reasons for not starting HT included it not being recommended by their physician (46%) and that it was not necessary (37%).

CONCLUSIONS

BRCA mutation carriers frequently undergo prophylactic BSO at young ages, and less than half report using HT. This study highlights barriers to HT use, such as patient fears and physician discouragement, and identifies potential areas to improve educational efforts.

BRCA carriers after risk-reducing bilateral salpingo-oophorectomy: menopausal hormone therapy knowledge gaps, and the impact of physicians' recommendations

OBJECTIVE

Female carriers of BRCA1/2 gene mutations are at an increased lifetime risk for breast and ovarian cancers. They are recommended to undergo risk-reducing surgery, including bilateral salpingo-oophorectomy (RR-BSO), upon completion of childbearing. RR-BSO surgery decreases morbidity and mortality but results in early menopause. Menopausal hormone therapy (MHT) is under-utilized despite being shown as safe for carriers. We aim to evaluate the factors associated with decision-making regarding MHT use following RR-BSO in healthy BRCA mutation carriers.

METHODS

Female carriers aged <50 years who underwent RR-BSO and were followed in a multidisciplinary clinic completed online multiple-choice and free-text questionnaires.

RESULTS

A total of 142 women met the inclusion criteria and filled the questionnaire: 83 were MHT users and 59 were non-users. MHT users underwent RR-BSO earlier than non-users (40.82 ± 3.91 vs. 42.88 ± 4.34; p < 0.0001). MHT usage was positively associated with MHT explanation (odds ratio 4.318, 95% confidence interval [CI] [1.341-13.902], p = 0.014), and knowledge regarding the safety of MHT and its effects on general health (odds ratio 2.001, 95% CI [1.443-2.774], p < 0.0001). MHT users and non-users retrospectively evaluated their comprehension of RR-BSO consequences as significantly lower than before surgery (p < 0.001).

CONCLUSION

Post-RR-BSO outcomes, including the effects on women's quality of life and its possible mitigation through MHT use, need to be addressed pre surgery by healthcare providers.

Comprehensive Care of Women With Genetic Predisposition to Breast and Ovarian Cancer

Women at risk for hereditary breast and ovarian cancer syndromes are frequently seen in primary care and gynecology clinics. They present with a distinctive set of clinical and emotional needs that revolve around complex risk management discussions and decision making. The care of these women calls for the creation of individualized care plans that facilitate adjustment to the mental and physical changes associated with their choices. This article provides an update on comprehensive evidence-driven care of women with hereditary breast and ovarian cancer. The aim of this review is to aid clinicians in identifying those at risk for hereditary cancer syndromes and provide practical advice on patient-centered medical and surgical risk management. Topics of discussion include enhanced surveillance, preventive medications, risk-reducing mastectomy and reconstruction, risk-reducing bilateral salpingo-oophorectomy, fertility, sexuality, and menopausal management, with attention to the importance of psychological support. High-risk patients may benefit from a multidisciplinary team that provides realistic expectations with consistent messaging. The primary care provider must be aware of the special needs of these patients and the consequences of their risk management interventions.

Use of exogenous hormones in those at increased risk for breast cancer: contraceptive and menopausal hormones in gene carriers and other high-risk patients

IMPORTANCE AND OBJECTIVE

Addressing the hormonal needs of individuals at increased risk of breast cancer (BC) can be a challenge. Observational, prospective, and case-control data support the safety of hormonal contraception in women, often with the added benefits of ovarian and endometrial cancer risk reduction. The majority of data on menopausal hormone therapy (HT) in the highest-risk patients comes from studies of patients with pathogenic variants in BRCA1 and BRCA2 who undergo early surgical menopause. The benefits of risk-reducing salpingo-oophorectomy are not minimized by HT, whereas its use mitigates accelerated osteoporosis and cardiovascular disease. In other patients at increased risk, such as with family history, studies have shown little risk with significant benefit.

METHODS

We review evidence to help women's health practitioners aid patients in making choices. The paper is divided into four parts: 1, contraception in the very high-risk patient (ie, with a highly penetrant BC predisposition gene); 2, contraception in other patients at increased risk; 3, menopausal HT in the gene carrier; and 4, HT in other high-risk patients.

DISCUSSION AND CONCLUSION

Women at increased risk for BC both early and later in life should be offered reassurance around the use of premenopausal and postmenopausal hormone therapies. The absolute risks associated with these therapies are low, even in the very high-risk patient, and the benefits are often substantial. Shared decision making is key in presenting options, and knowledge of the data in this area is fundamental to these discussions.

Hormone replacement therapy in BRCA mutation carriers: how shall we do no harm?

Women with a BRCA mutation have an increased risk of developing breast and ovarian cancer. Bilateral salpingo-oophorectomy is the only effective strategy to reduce this risk. Risk-reducing bilateral salpingo-oophorectomy (RRSO) is recommended between the ages of 35 and 40 for women carriers of BRCA1 and between the ages of 40 and 45 for women carriers of BRCA1 and BRCA2 mutations. Most women undergo this procedure prior to their natural menopause subsequently developing an anticipated lack of hormones. This condition affects the quality of life and longevity, while it is more pronounced in women carrying a BRCA1 mutation compared to BRCA2 because they are likely to have surgery earlier. Hormone replacement therapy (HRT) is the only strategy able to significantly compensate for the loss of ovarian hormone production and counteract menopausal symptoms. There is strong evidence that short-term HRT use does not increase the risk of breast cancer among women with a BRCA1 mutation. Few data are available on BRCA2 mutation carriers. Therefore, BRCA mutation carriers require careful counseling about the outcomes of their RRSO, including menopausal symptoms and/or the fear associated with HRT use.

Counselling of path_BRCA carriers who are considering risk-reducing oophorectomy

path_BRCA 1/2 increases a woman's lifetime risk of breast and ovarian cancer. Interventions can be offered which manage cancer risk; annual breast screening from age 30, chemoprevention and, once a woman's family is complete, risk-reducing surgery. The latter is the most effective method of reducing cancer in path_BRCA carriers; salpingo-oophorectomy reduces breast and ovarian cancer, respectively, by up to 50% and 95%. Factors affecting a woman's decision to undergo risk-reducing surgery are complex; dominant factors include risks of surgery, effect on cancer outcomes and menopausal sequelae. Specific information relating to hormone replacement and non-hormonal alternatives are an important consideration for women but, are often overlooked. Informative counselling is required to enable satisfaction with the chosen intervention whilst improving survival outcomes. This review paper outlines the current data pertaining to these decision-making factors and provides a proforma to enable effective counselling.

Long-Term Non-Cancer Risks in People with BRCA Mutations following Risk-Reducing Bilateral Salpingo-Oophorectomy and the Role of Hormone Replacement Therapy: A Review

Risk-reducing bilateral salpingo-oophorectomy (RRBSO) is the gold standard preventative option for BRCA mutation carriers at high risk for ovarian and breast cancer. However, when performed at the recommended ages of 35-45 years, RRBSO induces immediate premature surgical menopause, along with the accompanying adverse psychosocial, cardiovascular, bone, and cognitive health consequences. While these health consequences have been thoroughly studied in the general population, little is known about the long-term health outcomes in the BRCA population. Hormone replacement therapy (HRT) until the average age of natural menopause can help mitigate these health risks, yet the initiation of HRT is a complex decision among BRCA carriers due to concern of increasing the already high risk of breast cancer in these people. This review summarizes the current research on long-term non-cancer risks in BRCA carriers following RRBSO-induced premature surgical menopause, and highlights the existing evidence in support of HRT use in this population.

Using menopausal hormone therapy after a cancer diagnosis in Ireland

BACKGROUND

Menopause may cause a constellation of symptoms that affect quality of life. Many women will have menopause induced or exacerbated by treatment for cancer whether that be through surgery, chemotherapy, radiotherapy, or anti-endocrine therapy. As treatments advance, the number of people living with and beyond a cancer diagnosis is set to increase over the coming years meaning more people will be dealing with the after effects of cancer and its treatment.

AIMS

This review aims to summarise available data to guide clinicians treating women with menopausal symptoms after the common cancer diagnoses encountered in Ireland. The use of menopausal hormone therapy is discussed as well as non-hormonal and non-pharmacological options.

CONCLUSIONS

Managing menopausal symptoms is an important consideration for all physicians involved in the care of people living with and beyond a cancer diagnosis. High-quality data may not be available to guide treatment decisions, and, thus, it is essential to take into account the impact of the symptoms on quality of life as well as the likelihood of recurrence in each individual case.

The Role of Hormonal Replacement Therapy in BRCA Mutated Patients: Lights and Shadows

All cancers develop as a result of mutations in genes. DNA damage induces genomic instability and subsequently increases susceptibility to tumorigenesis. Women who carry mutations of BRCA 1 and BRCA2 genes have an augmented risk of breast and ovarian cancer and a markedly augmented probability of dying because of cancer compared to the general population. As a result, international guidelines recommend that all BRCA1\2 mutation carriers be offered risk-reducing bilateral salpingo-oophorectomy at an early age to reduce the risk of cancer and decrease the mortality rate of this high-risk population. NCCN guidelines recommend risk-reducing bilateral salpingo-oophorectomy in pre-menopausal women, between 35-40 years in BRCA1 mutation carriers and between 40-45 years in BRCA2 mutation carriers. Unfortunately, the well-documented reduction of cancer risk is counterbalanced by early sterility and premature ovarian failure with an early onset of secondary menopausal syndromes such as neuromotor, cardiovascular, cognitive and urogenital deficiency. Hormonal replacement therapy significantly compensates for hormonal deprivation and counteracts menopausal syndrome morbidity and mortality; however, some data suggest a possible correlation between hormonal medications and cancer risk, especially in BRCA1\2 carriers who undergo long-term regimens. Conversely, short-term treatment before the age of natural menopause does not appear to increase the cancer risk in BRCA1 mutation carriers without a personal history of breast cancer after prophylactic surgery. Few data are available on BRCA2 mutation carriers and more well-designed studies are needed. In conclusion, clinicians should propose short-term hormone replacement therapy to BRCA 1 carriers to counteract hormonal deprivation; personalized counselling should be offered to BRCA2 mutation carriers for a balance between the risks and benefits of the treatment.

Eligibility criteria for Menopausal Hormone Therapy (MHT): a position statement from a consortium of scientific societies for the use of MHT in women with medical conditions. MHT Eligibility Criteria Group

This project aims to develop eligibility criteria for menopausal hormone therapy (MHT). The tool should be similar to those already established for contraception A consortium of scientific societies coordinated by the Spanish Menopause Society met to formulate recommendations for the use of MHT by women with medical conditions based on the best available evidence. The project was developed in two phases. As a first step, we conducted 14 systematic reviews and 32 metanalyses on the safety of MHT (in nine areas: age, time of menopause onset, treatment duration, women with thrombotic risk, women with a personal history of cardiovascular disease, women with metabolic syndrome, women with gastrointestinal diseases, survivors of breast cancer or of other cancers, and women who smoke) and on the most relevant pharmacological interactions with MHT. These systematic reviews and metanalyses helped inform a structured process in which a panel of experts defined the eligibility criteria according to a specific framework, which facilitated the discussion and development process. To unify the proposal, the following eligibility criteria have been defined in accordance with the WHO international nomenclature for the different alternatives for MHT (category 1, no restriction on the use of MHT; category 2, the benefits outweigh the risks; category 3, the risks generally outweigh the benefits; category 4, MHT should not be used). Quality was classified as high, moderate, low or very low, based on several factors (including risk of bias, inaccuracy, inconsistency, lack of directionality and publication bias). When no direct evidence was identified, but plausibility, clinical experience or indirect evidence were available, "Expert opinion" was categorized. For the first time, a set of eligibility criteria, based on clinical evidence and developed according to the most rigorous methodological tools, has been defined. This will provide health professionals with a powerful decision-making tool that can be used to manage menopausal symptoms.

Controversies and Open Questions in Management of Cancer-Free Carriers of Germline Pathogenic Variants in BRCA1/BRCA2

Females harboring germline BRCA1/BRCA2 (BRCA) P/LPV are offered a tight surveillance scheme from the age of 25−30 years, aimed at early detection of specific cancer types, in addition to risk-reducing strategies. Multiple national and international surveillance guidelines have been published and updated over the last two decades from geographically diverse countries. We searched for guidelines published between 1 January 2015 and 1 May 2022. Differences between guidelines on issues such as primary prevention, mammography screening in young (<30 years) carriers, MRI screening in carriers above age 65 years, breast imaging (if any) after risk-reducing bilateral mastectomy, during pregnancy, and breastfeeding, and hormone-replacement therapy, are just a few notable examples. Beyond formal guidelines, BRCA carriers’ concerns also focus on the timing of risk-reducing surgeries, fertility preservation, management of menopausal symptoms in cancer survivors, and pancreatic cancer surveillance, issues that, for some, there are no data to support evidence-based recommendations. This review discusses these unsettled issues, emphasizing the importance of future studies to enable global guideline harmonization for optimal surveillance strategies. Moreover, it raises the unmet need for personalized risk stratification and surveillance in BRCA P/LPV carriers.

Contraception and Hormone Replacement Therapy in Healthy Carriers of Germline BRCA1/2 Genes Pathogenic Variants: Results from an Italian Survey

Several myths and misconceptions exist about hormones in women with familial predisposition to cancer, and there are few real-life data on their prescription and uptake. To better understand how they are prescribed and accepted in healthy carriers of a BRCA1/2 pathogenetic variant, an online survey was uploaded on Google Forms and shared through social media closed groups of patients' associations, aBRCAcadabra and ACTO Campania. A total of 241 questionnaires were collected. Sexual quality of life was considered of the utmost importance by most of the respondents (mean score of 7 ± 2.8/10), but they felt the counseling they received by healthcare professionals on the topic was insufficient (4.9 ± 3.2/10). Only 57 women out of 233 (24.5%) had used hormonal contraception after being diagnosed as carriers of a BRCA pathogenetic variant, and 42 out of 148 (28.4%) underwent menopause hormonal therapy. The majority of women (53.6% for contraception and 61.5% for menopause) reported being dissatisfied with the counseling received, and 58.2% were not aware of the protective effect of hormonal contraception on the risk of ovarian cancer. An educational effort is desirable to guarantee healthy BRCA carriers reliable contraception and evidence-based menopause counseling.

Bilateral Oophorectomy and the Risk of Breast Cancer in BRCA1 Mutation Carriers: A Reappraisal

BACKGROUND

The lack of consensus on whether bilateral oophorectomy impacts risk of developing breast cancer among BRCA1 mutation carriers might be attributed to various biases, specifically, cancer-induced testing bias due to inclusion of prevalent cases. We conducted two complementary matched case-control analyses to evaluate the association of oophorectomy and BRCA1 breast cancer.

METHODS

A research questionnaire was administered every two years to collect information on exposures and disease. In the first analysis, we limited the study to prevalent breast cancer cases (diagnosed prior to study entry; n = 2,962) who were matched to controls on year of birth and country of residence (n = 4,358). In the second approach, we limited to 330 incident cases (diagnosed in the follow-up period) and 1,548 matched controls. Conditional logistic regression was used to estimate the adjusted odds ratios (OR) and 95% confidence intervals (CI) of invasive breast cancer.

RESULTS

In the first approach, there was a significant inverse association between oophorectomy and the risk of developing breast cancer [OR = 0.43; 95% confidence interval (CI), 0.34-0.55; P < 00001]. In the second approach, there was no association between oophorectomy and risk (OR = 1.21; 95% CI, 0.87-1.70; P = 0.26).

CONCLUSIONS

The inclusion of women with a personal history of breast cancer prior to ascertainment likely impacts upon the association of oophorectomy and BRCA1 breast cancer risk.

IMPACT

Oophorectomy is unlikely a determinant of breast cancer risk in BRCA1 mutation carriers but should be offered at age 35 to reduce the risk of ovarian and fallopian tube cancer.

Management of menopause: a view towards prevention

Women spend approximately one-third of their lives with menopause, which occurs around 50 years of age. It is now appreciated that several important metabolic and cardiovascular disease risks emerge during the menopausal transition. Many important conditions occur 10-15 years after menopause, including weight gain and obesity, metabolic syndrome, diabetes, osteoporosis, arthritis, cardiovascular disease, dementia, and cancer; therefore, the occurrence of menopause heralds an important opportunity to institute preventative strategies. These strategies will lead to improved quality of life and decreased mortality. Various strategies are presented for treating symptoms of menopause and diseases that are asymptomatic. Among several strategies is the use of hormone therapy, which has efficacy for symptoms and osteoporosis, and can improve metabolic and cardiovascular health. When instituted early, which is key, in younger postmenopausal women (under 60 years) oestrogen has been found to consistently decrease mortality with a favourable risk-benefit profile in low-risk women. Prospective data show that long-term therapy might not be required for this benefit.

Endometrial Cancer and BRCA Mutations: A Systematic Review

This systematic review identifies, evaluates, and summarises the findings of all relevant individual studies on the prevalence of BRCA mutation (BRCAm) in endometrial cancer patients and the incidence of endometrial cancer in BRCAm women patients. Consequently, the benefits and limits of a prophylactic hysterectomy at the time of the risk-reducing salpingo-oophorectomy are analysed and discussed. A systematic literature search was performed in the databases of PubMed, Cochrane, and Web of Science until May 2022; 13 studies met the eligibility criteria. Overall, 1613 endometrial cancer patients from 11 cohorts were tested for BRCA1/2 mutation. BRCA1/2m were identified in 4.3% of women with endometrial cancer (70/1613). BRCA1m was the most represented (71.4%) pathogenic variant. Alongside, a total of 209 BRCAm carriers from 14 studies were diagnosed with endometrial cancer. Only 5 out of 14 studies found a correlation between BRCAm and an increased risk of endometrial cancer. Nevertheless, two studies found a statistical difference only for BRCA1m women. The present systematic review does not provide strong evidence in favour of performing routine hysterectomy at the time of risk-reducing salpingo-oophorectomy; however, it provides epidemiological data that can be useful for counselling patients in order to offer a tailored approach.

Delineating the role of osteoprotegerin as a marker of breast cancer risk among women with a BRCA1 mutation

Women with a pathogenic germline mutation in the BRCA1 gene face a very high lifetime risk of developing breast cancer, estimated at 72% by age 80. Prophylactic bilateral mastectomy is the only effective way to lower their risk; however, most women with a mutation opt for intensive screening with annual MRI and mammography. Given that the BRCA1 gene was identified over 20 years ago, there is a need to identify a novel non-surgical approach to hereditary breast cancer prevention. Here, we provide a review of the emerging preclinical and epidemiologic evidence implicating the dysregulation of progesterone-mediated receptor activator of nuclear factor κB (RANK) signaling in the pathogenesis of BRCA1-associated breast cancer. Experimental studies have demonstrated that RANK inhibition suppresses Brca1-mammary tumorigenesis, suggesting a potential target for prevention. Data from studies conducted among women with a BRCA1 mutation further support this pathway in BRCA1-associated breast cancer development. Progesterone-containing (but not estrogen-alone) hormone replacement therapy is associated with an increased risk of breast cancer in women with a BRCA1 mutation. Furthermore, BRCA1 mutation carriers have significantly lower levels of circulating osteoprotegerin (OPG), the decoy receptor for RANK-ligand (RANKL) and thus endogenous inhibitor of RANK signaling. OPG levels may be associated with the risk of disease, suggesting a role of this protein as a potential biomarker of breast cancer risk. This may improve upon current risk prediction models, stratifying women at the highest risk of developing the disease, and further identify those who may be targets for anti-RANKL chemoprevention. Collectively, the evidence supports therapeutic inhibition of the RANK pathway for the primary prevention of BRCA1-associated breast cancer, which may generate unique prevention strategies (without prophylactic surgery) and enhance quality of life.

Association of Hypertension and Breast Cancer: Antihypertensive Drugs as an Effective Adjunctive in Breast Cancer Therapy

Breast cancer (BC) is the most common malignancy affecting women, and its incidence in younger women is rising worldwide. Early-onset of BC is a multi-step process involving various biological aggressive tumors such as triple negative and human epidermal growth factor 2 (HER2)-positive cancers. BC prevention is still arduous across the globe. A series of observational studies have established a conclusive non-genetic clinical link between hypertension (HTN) and the development of invasive BC. Those clinical associations have driven a pharmacological seek to use the anti-hypertension (AHTN) drugs as an effective adjunctive in BC therapy. The use of AHTN, especially beta-blockers and thiazides, has been recognized as a potent anti-tumor drug to mitigate BC progression, reduce the side effects of cancer treatment, and stop the reoccurrence of cancer in the survivors. Considering the dire need to disseminate the research on how AHTN drugs can be opted as the effective adjunctive therapy to cure the BC, the current review aimed to provide an update on novel understandings on association and mechanisms of AHTN-drugs against BC as an additional cancer therapy.

Risk of de novo cancer after premenopausal bilateral oophorectomy

BACKGROUND

Hysterectomy is one of the most frequent gynecologic surgeries in the United States. Women undergoing hysterectomy are commonly offered bilateral oophorectomy for ovarian and breast cancer prevention. Although bilateral oophorectomy may dramatically reduce the risk of gynecologic cancers, some studies suggested that bilateral oophorectomy may be associated with an increased risk of other types of cancer, such as lung cancer and colorectal cancer. However, the results are conflicting.

OBJECTIVE

To study the association between bilateral oophorectomy and the risk of subsequent cancer of any type.

STUDY DESIGN

This population-based cohort study included all premenopausal women who underwent bilateral oophorectomy for a nonmalignant indication before the age of 50, between January 1, 1988 and December 31, 2007 in Olmsted County, Minnesota, and a random sample of age-matched (±1 year) referent women who did not undergo bilateral oophorectomy. Women with cancer before oophorectomy (or index date) or within 6 months after the index date were excluded. Time-to-event analyses were performed to assess the risk of de novo cancer. Cancer diagnosis and type were confirmed using medical record review.

RESULTS

Over a median follow-up of 18 years, the risk of any cancer did not significantly differ between the 1562 women who underwent bilateral oophorectomy before natural menopause and the 1610 referent women (adjusted hazard ratio, 0.82; 95% confidence interval, 0.66-1.03). However, women who underwent bilateral oophorectomy had a decreased risk of gynecologic cancers (adjusted hazard ratio, 0.15; 95% confidence interval, 0.06-0.34) but not of nongynecologic cancers (adjusted hazard ratio, 0.99; 95% confidence interval, 0.78-1.26). In particular, the risk of breast cancer, gastrointestinal cancer, and lung cancer did not differ between these 2 cohorts. Use of estrogen therapy through the age of 50 years in women who underwent bilateral oophorectomy did not modify the results.

CONCLUSION

Women who underwent bilateral oophorectomy before menopause have a reduced risk of gynecologic cancer but not of other types of cancer including breast cancer. Women at average risk of ovarian cancer should not consider bilateral oophorectomy for the prevention of breast cancer or other nongynecologic cancers.

Risk-Reducing Options for High-Grade Serous Gynecologic Malignancy in BRCA1/2

Ovarian cancer (OC) is the leading cause of death among women with gynecologic malignancy. Breast Cancer Susceptibility Gene 1 (BRCA 1) and Breast Cancer Susceptibility Gene 2 (BRCA 2) germline mutations confer an estimated 20 to 40 times increased risk of OC when compared to the general population. The majority of BRCA-associated OC is identified in the late stage, and no effective screening method has been proven to reduce mortality. Several pharmacologic and surgical options exist for risk-reduction of gynecologic malignancy in BRCA 1/2 mutation carriers. This review summarizes up-to-date research on pharmacologic risk-reducing interventions, including the oral contraceptive pill, acetylsalicylic acid/nonsteroidal anti inflammatory drugs (ASA/NSAID) therapy, and denosumab, and surgical risk-reducing interventions, including risk-reducing bilateral salpingo-oophorectomy, salpingectomy with delayed oophorectomy, and hysterectomy at the time of risk-reducing bilateral salpingo-oophorectomy.

Risk-Reducing Salpingo-Oophorectomy and the Use of Hormone Replacement Therapy Below the Age of Natural Menopause: Scientific Impact Paper No. 66 October 2021: Scientific Impact Paper No. 66

This paper deals with the use of hormone replacement therapy (HRT) after the removal of fallopian tubes and ovaries to prevent ovarian cancer in premenopausal high risk women. Some women have an alteration in their genetic code, which makes them more likely to develop ovarian cancer. Two well-known genes which can carry an alteration are the BRCA1 and BRCA2 genes. Examples of other genes associated with an increased risk of ovarian cancer include RAD51C, RAD51D, BRIP1, PALB2 and Lynch syndrome genes. Women with a strong family history of ovarian cancer and/or breast cancer, may also be at increased risk of developing ovarian cancer. Women at increased risk can choose to have an operation to remove the fallopian tubes and ovaries, which is the most effective way to prevent ovarian cancer. This is done after a woman has completed her family. However, removal of ovaries causes early menopause and leads to hot flushes, sweats, mood changes and bone thinning. It can also cause memory problems and increases the risk of heart disease. It may reduce libido or impair sexual function. Guidance on how to care for women following preventative surgery who are experiencing early menopause is needed. HRT is usually advisable for women up to 51 years of age (average age of menopause for women in the UK) who are undergoing early menopause and have not had breast cancer, to minimise the health risks linked to early menopause. For women with a womb, HRT should include estrogen coupled with progestogen to protect against thickening of the lining of the womb (called endometrial hyperplasia). For women without a womb, only estrogen is given. Research suggests that, unlike in older women, HRT for women in early menopause does not increase breast cancer risk, including in those who are BRCA1 and BRCA2 carriers and have preventative surgery. For women with a history of receptor-negative breast cancer, the gynaecologist will liaise with an oncology doctor on a case-by-case basis to help to decide if HRT is safe to use. Women with a history of estrogen receptor-positive breast cancer are not normally offered HRT. A range of other therapies can be used if a woman is unable to take HRT. These include behavioural therapy and non-hormonal medicines. However, these are less effective than HRT. Regular exercise, healthy lifestyle and avoiding symptom triggers are also advised. Whether to undergo surgery to reduce risk or not and its timing can be a complex decision-making process. Women need to be carefully counselled on the pros and cons of both preventative surgery and HRT use so they can make informed decisions and choices.

A prospective multicentric study of risk-reducing salpingo-oophorectomy in BRCA mutation patients

BACKGROUND AND AIM OF THE WORK

BRCA1/2 are tumour-suppressor genes involved in DNA homologous recombination and ovarian cancer development.  The study evaluated the risk of tumor cancer in women presenting the BRCA mutations.

METHODS

Risk-reducing surgery (RRS) was performed in 100 patients carrying BRCA1 (aged between 30-73 years, median age was 51 years) and BRCA 2 mutation (aged between 36-70 years, median age was 53 years). Fifty-eight patients had previous history of breast cancer.

RESULTS

Between the 100 patients, 82 women underwent risk-reducing salpingo-oophorectomy (RRSO) through a laparoscopic minimally invasive approach, 7 (7 %) underwent laparoscopic RRSO and contextual hysterectomy, 1 woman (1 %) underwent RRSO through a laparotomic approach and 10 women (10 %) laparotomic RRSO and hysterectomy. During 5 (5 %) laparoscopic RRSO, prophylactic bilateral mastectomy was also performed. Early and late complication occurred in 3 patients (3 %). Two patients (2 %) were found to have occult Serous Tubal Intraepithelial Carcinoma (STIC) and three patients (3 %) occult cancer.

CONCLUSIONS

RRSO is safe and feasible in BRCA mutation carriers. The procedure is effective for genetic prevention of ovarian cancer.

Menopausal hormone therapy in women with benign gynaecological conditions and cancer

The efficacy of menopausal hormone therapy for bothersome menopausal symptoms is well established. However, there are a range of benign and malignant gynaecological conditions that pose a challenge in managing menopausal symptoms. Their hormone-dependent nature either raises concerns about symptom recurrence or malignant disease progression making decisions about menopausal hormone therapy complex for both clinicians and patients. It appears there is a small potential for symptom recurrence with menopausal hormone therapy use in menopausal women with a history of severe endometriosis. Malignant transformation of previous endometriotic lesions is likely to be rare but is not adequately understood. In this setting, combined hormone therapy is preferred, including in woman post-hysterectomy. Uterine fibroids are not a contraindication to menopausal hormone therapy use but women with large fibroids at menopause should have regular follow-up of their fibroids. Generally, menopausal hormone therapy is considered appropriate for women with cervical cancer and most ovarian cancers except for low grade serous tumours. Endometrial cancer requires an individualised discussion. The overall quality of data in this area is poor but suggests women with a low risk of recurrence may consider hormonal therapy, balancing symptom impact with prognosis.

Menopausal hormone therapy and breast cancer risk

This narrative review analyses the customization of Menopause Hormone Therapy in the context of breast cancer risk in women with premature ovarian insufficiency (POI) and with menopause at a normal age. Women with Idiopathic POI, FMR-1 premutation or Turner syndrome, if left untreated, may have lower breast cancer risk compared to the healthy age-matched female population. These women should be treated with MHT until the age of 50, as the risk of breast cancer is equal to that of normally menstruating women. Carriers of BRCA 1 & 2 mutation after risk-reducing bilateral salpingo-oophorectomy (RRSO), without a personal history of cancer, have an increased breast cancer risk, but may probably be treated with MHT till the age of 50. POI resulting from endometriosis or cancer related treatment is discussed in a separate paper in this issue. In peri- and postmenopausal women with menopausal symptoms and/or risk factors for osteoporosis in need of MHT, the individual breast cancer risk can be evaluated using internet-based calculators. In most women the 5-year-breast cancer risk is low (<3%) and MHT is a safe option. MHT should be prescribed with caution in women who have an intermediate risk (3-6%) and should not be prescribed in those who have a high risk of breast cancer (>6%). Oestrogen-only MHT and oestrogen-progestogen MHT containing micronized progesterone or dydrogesterone are associated with lower breast cancer risk compared to other combined MHT regimens.

The evolving role of the Women's Health Specialist in cancer prevention and survivorship

IMPORTANCE AND OBJECTIVE

This review provides a framework for primary care physicians, internists, family doctors, NP's, PA's, and oncologists caring for women-henceforth referred to as Women's Health Specialists-to identify and screen patients who may be at high risk for inherited cancer syndromes; an intervention referred to as previvorship care. For women who undergo risk-reducing oophorectomy, survivorship care is critical to optimizing quality of life thereafter. In this paper, we review management of the unique survivorship needs and management options for women at risk for or with a cancer diagnosis, highlighting the importance of interdisciplinary care.

METHODS

To review the available previvorship and survivorship management strategies, a Pub Med search was performed using keywords "survivorship," "genetics," "cancer," "menopause," "hormone therapy," "screening" in addition to review of guidelines, position statements and expert, and committee opinions from the American College of OBGYN, the American Society of Clinical Oncology, The North American Menopause Society, the National Comprehensive Cancer Network , and the American Society for Reproductive Medicine.

DISCUSSION AND CONCLUSION

Women's Health Specialists are in a unique position to identify and screen women who may be at risk for inherited cancer syndromes as well as provide necessary survivorship management following transition from their oncologists' care.

Hormone therapy in the postmenopausal years: considering benefits and risks in clinical practice

BACKGROUND

Menopausal symptoms can be very distressing and considerably affect a woman's personal and social life. It is becoming more and more evident that leaving bothersome symptoms untreated in midlife may lead to altered quality of life, reduced work productivity and, possibly, overall impaired health. Hormone therapy (HT) for the relief of menopausal symptoms has been the object of much controversy over the past two decades. At the beginning of the century, a shadow was cast on the use of HT owing to the concern for cardiovascular and cerebrovascular risks, and breast cancer, arising following publication of a large randomized placebo-controlled trial. Findings of a subanalysis of the trial data and extended follow-up studies, along with other more modern clinical trials and observational studies, have provided new evidence on the effects of HT.

OBJECTIVE AND RATIONALE

The goal of the following paper is to appraise the most significant clinical literature on the effects of hormones in postmenopausal women, and to report the benefits and risks of HT for the relief of menopausal symptoms.

SEARCH METHODS

A Pubmed search of clinical trials was performed using the following terms: estrogens, progestogens, bazedoxifene, tibolone, selective estrogen receptor modulators, tissue-selective estrogen complex, androgens, and menopause.

OUTCOMES

HT is an effective treatment for bothersome menopausal vasomotor symptoms, genitourinary syndrome, and prevention of osteoporotic fractures. Women should be made aware that there is a small increased risk of stroke that tends to persist over the years as well as breast cancer risk with long-term estrogen-progestin use. However, healthy women who begin HT soon after menopause will probably earn more benefit than harm from the treatment. HT can improve bothersome symptoms, all the while conferring offset benefits such as cardiovascular risk reduction, an increase in bone mineral density and a reduction in bone fracture risk. Moreover, a decrease in colorectal cancer risk is obtainable in women treated with estrogen-progestin therapy, and an overall but nonsignificant reduction in mortality has been observed in women treated with conjugated equine estrogens alone or combined with estrogen-progestin therapy. Where possible, transdermal routes of HT administration should be preferred as they have the least impact on coagulation. With combined treatment, natural progesterone should be favored as it is devoid of the antiapoptotic properties of other progestogens on breast cells. When beginning HT, low doses should be used and increased gradually until effective control of symptoms is achieved. Unless contraindications develop, patients may choose to continue HT as long as the benefits outweigh the risks. Regular reassessment of the woman's health status is mandatory. Women with premature menopause who begin HT before 50 years of age seem to have the most significant advantage in terms of longevity.

WIDER IMPLICATIONS

In women with bothersome menopausal symptoms, HT should be considered one of the mainstays of treatment. Clinical practitioners should tailor HT based on patient history, physical characteristics, and current health status so that benefits outweigh the risks.

Controversies in Hereditary Cancer Management

Personalized management of patients at risk ideally should involve a multidisciplinary team of not only genetic counselors and surgeons, but also women's health or menopause specialists, knowledgeable psychologists, and primary care providers or obstetrician-gynecologists aware of the risks and fears "previvors" (survivors of a predisposition to cancer who have not had the disease) face as well as the issues that are common postoperatively. Identification of patients at risk for hereditary cancer, understanding of current genetic testing modalities and potential results, knowledge about screening and prevention including timing of surveillance, preventive medication and risk-reducing surgeries, understanding limitations and comorbidities associated with these risk management strategies and long-term psychological support are all important in hereditary cancer management. We describe issues surrounding the identification of the high-risk patient, universal testing in breast and ovarian cancer, and testing in special populations. We describe a simplified approach to understanding and communicating genetic testing results and nuances of testing including direct-to-consumer testing. We highlight concerns surrounding breast cancer screening during pregnancy and lactation. A framework for practical management and counseling of women who opt for risk-reducing salpingo-oophorectomy or risk-reducing mastectomy or both is provided. We provide an in-depth discussion of questions that arise in relation to timing of surgery, fertility preservation, management of menopausal symptoms, and surgical technique. Alternative choices in women who choose to delay bilateral salpingo-oophorectomy are reviewed. Finally, the psychosocial effects of carrying a genetic mutation and the issues that women face when undergoing to risk-reducing surgery including adjustment, sexuality issues, and cosmesis are addressed.

Cardiovascular health after menopause transition, pregnancy disorders, and other gynaecologic conditions: a consensus document from European cardiologists, gynaecologists, and endocrinologists

Women undergo important changes in sex hormones throughout their lifetime that can impact cardiovascular disease risk. Whereas the traditional cardiovascular risk factors dominate in older age, there are several female-specific risk factors and inflammatory risk variables that influence a woman’s risk at younger and middle age. Hypertensive pregnancy disorders and gestational diabetes are associated with a higher risk in younger women. Menopause transition has an additional adverse effect to ageing that may demand specific attention to ensure optimal cardiovascular risk profile and quality of life. In this position paper, we provide an update of gynaecological and obstetric conditions that interact with cardiovascular risk in women. Practice points for clinical use are given according to the latest standards from various related disciplines (Figure 1).

Ovarian cancer arising from the proximal fallopian tube in a patient with a BRCA2 mutation

•

BRCA1/2 carriers are at high risk for fallopian tube carcinoma, which can arise in the proximal fallopian tube.

•

Pathologic analysis of RRBSO specimens should include serial sectioning of the entire tube, not just the fimbriated end.

•

Concurrent hysterectomy at time of RRBSO may be considered to ensure all tubal epithelium is resected.

Patients with BRCA mutations are at high risk of high grade serous ovarian cancer. A paradigm shift has resulted in the current understanding that many cases of ovarian cancer actually arise from the fimbriated fallopian tube. The case presented here involves fallopian tube carcinoma arising from the cornua of the uterus in a BRCA2 carrier. This case suggests that pathologic analysis of risk-reducing bilateral salpingo-oophorectomy (RRBSO) specimens via serial sectioning and extensively examining the fimbriated end (SEE-FIM) may be insufficient to diagnose all occult lesions of interest. This case also provides a new consideration in the ongoing debate over the role of concurrent hysterectomy at time of RRBSO in BRCA carriers.

BRCA mutation carriers' perceptions on postmenopausal hormone therapy: An Italian study

Objective

To evaluate the actual perceptions of postmenopausal hormone therapy (HT) in BRCA mutation carriers (BRCAmc) in comparison with women from the general population.

Methods

Questionnaire‐based study of 83 BRCAmc and a control group of 89 women without a genetic mutation. Perceptions were evaluated by specific questions and Likert scales (−5–+5).

Results

Present and past users of HT were more frequent in the control group (p = 0.01), with a longer time of use (p = 0.03). The preferred route of administration of HT was ‘oral’ (54.6%). The most frequently reported adverse effect of HT was venous thrombosis (0.8), while a protective effect on bone health was reported. No noticeable beneficial effects of HT have been recognised for hot flushes (0.2) and vaginal dryness (0.1). The most frequently perceived beneficial and adverse effects of HT were not significantly different between BRCA mutation carriers and controls. The greatest oncological fear was breast cancer (1.0). The protective role of HT on colorectal cancer was not known (0.1). These oncological impacts were mostly overestimated in BRCAmc, however this was not significant. Few BRCAmc would think of taking HT after risk‐reducing surgeries.

Conclusions

Knowledge of the effects of HT on BRCAmc is relatively poor and they are likely to overstate its negative effects and underestimate its health benefits; however, this is not significant in comparison to the general population. More and better information should be given to BRCAmc to allow them to make informed decisions about the use of HT, especially before undergoing risk‐reducing surgeries.
