The Concept behind the Suitability of Menstrual Blood-Derived Stem Cells for the Management of Vaginal Atrophy among BRCA Mutation Carriers after RRSO

Risk-reducing bilateral salpingo-oophorectomy (RRSO) is recommended for breast cancer gene 1 (BRCA1) and 2 (BRCA2) mutation carriers. A major consequence of RRSO is surgical menopause associated with severe menopausal symptoms, mostly genitourinary complaints. Due to the inherent breast cancer risk, estrogen-based therapies are generally avoided in these patients. So far, the non-hormonal approaches available are not efficient to successfully treat the disabling vaginal atrophy-related symptoms. In regenerative medicine, mesenchymal stem cells (MSC) are the most frequently used cell type due to their remarkable and regenerative characteristics. Therapies based on MSC have revealed positive outcomes regarding symptoms and signs associated with vaginal atrophy by promoting angiogenesis, vaginal restoration, and the proliferation of vaginal mucosa cells. Menstrual blood-derived stem cells (MenSC) are a novel source of MSC, with promising therapeutic potential directly linked to their high proliferative rates; low immunogenicity; non-invasive, easy, and periodic acquisition; and almost no associated ethical issues. In this review, we update the current knowledge and research regarding the potential value of previously preserved MenSC in the therapy of vaginal atrophy among BRCA mutation carriers subjected to RRSO.

Scarless preventive surgery

Oncogenetic risk‐reduction surgeries could be better accepted if innovation allowed the scars to be hidden. Adnexectomies, vNotes, and endoscopic mastectomies presented here are examples.

Quality of life after risk-reducing surgery for breast and ovarian cancer prevention: a systematic review and meta-analysis

OBJECTIVE

This study aimed to assess the impact of risk-reducing surgery for breast cancer and ovarian cancer prevention on quality of life. We considered risk-reducing mastectomy, risk-reducing salpingo-oophorectomy, and risk-reducing early salpingectomy and delayed oophorectomy.

DATA SOURCES

We followed a prospective protocol (International Prospective Register of Systematic Reviews: CRD42022319782) and searched MEDLINE, Embase, PubMed, and Cochrane Library from inception to February 2023.

STUDY ELIGIBILITY CRITERIA

We followed a PICOS (population, intervention, comparison, outcome, and study design) framework. The population included women at increased risk of breast cancer or ovarian cancer. We focused on studies reporting quality of life outcomes (health-related quality of life, sexual function, menopause symptoms, body image, cancer-related distress or worry, anxiety, or depression) after risk-reducing surgery, including risk-reducing mastectomy for breast cancer and risk-reducing salpingo-oophorectomy or risk-reducing early salpingectomy and delayed oophorectomy for ovarian cancer.

METHODS

We used the Methodological Index for Non-Randomized Studies (MINORS) for study appraisal. Qualitative synthesis and fixed-effects meta-analysis were performed.

RESULTS

A total of 34 studies were included (risk-reducing mastectomy: 16 studies; risk-reducing salpingo-oophorectomy: 19 studies; risk-reducing early salpingectomy and delayed oophorectomy: 2 studies). Health-related quality of life was unchanged or improved in 13 of 15 studies after risk-reducing mastectomy (N=986) and 10 of 16 studies after risk-reducing salpingo-oophorectomy (N=1617), despite short-term deficits (N=96 after risk-reducing mastectomy and N=459 after risk-reducing salpingo-oophorectomy). Sexual function (using the Sexual Activity Questionnaire) was affected in 13 of 16 studies (N=1400) after risk-reducing salpingo-oophorectomy in terms of decreased sexual pleasure (-1.21 [-1.53 to -0.89]; N=3070) and increased sexual discomfort (1.12 [0.93-1.31]; N=1400). Hormone replacement therapy after premenopausal risk-reducing salpingo-oophorectomy was associated with an increase (1.16 [0.17-2.15]; N=291) in sexual pleasure and a decrease (-1.20 [-1.75 to -0.65]; N=157) in sexual discomfort. Sexual function was affected in 4 of 13 studies (N=147) after risk-reducing mastectomy, but stable in 9 of 13 studies (N=799). Body image was unaffected in 7 of 13 studies (N=605) after risk-reducing mastectomy, whereas 6 of 13 studies (N=391) reported worsening. Increased menopause symptoms were reported in 12 of 13 studies (N=1759) after risk-reducing salpingo-oophorectomy with a reduction (-1.96 [-2.81 to -1.10]; N=1745) in the Functional Assessment of Cancer Therapy - Endocrine Symptoms. Cancer-related distress was unchanged or decreased in 5 of 5 studies after risk-reducing mastectomy (N=365) and 8 of 10 studies after risk-reducing salpingo-oophorectomy (N=1223). Risk-reducing early salpingectomy and delayed oophorectomy (2 studies, N=413) led to better sexual function and menopause-specific quality of life.

CONCLUSION

Risk-reducing surgery may be associated with quality of life outcomes. Risk-reducing mastectomy and risk-reducing salpingo-oophorectomy reduce cancer-related distress, and do not affect health-related quality of life. Women and clinicians should be aware of body image problems after risk-reducing mastectomy, and of sexual dysfunction and menopause symptoms after risk-reducing salpingo-oophorectomy. Risk-reducing early salpingectomy and delayed oophorectomy may be a promising alternative to mitigate quality of life-related risks of risk-reducing salpingo-oophorectomy.

Surgical options for patients with early-stage breast cancer and pathogenic germline variants: an oncologist perspectives

Breast cancer continues to be the most common cancer diagnosed among women worldwide. Family history of breast cancer is frequently encountered, and 5-15% of patients may carry inherited pathogenic germline variants, identification of which can be helpful for both; patients themselves and their unaffected close relatives. The availability and affordability of molecular diagnostics, like next generation sequencing (NGS), had resulted in wider adoption of such technologies to detect pathogenic variants of cancer-predisposing genes. International guidelines had recently broadened the indications for germline genetic testing to include much more patients, and also expanded the testing to include multi-gene panels, while some professional societies are calling for universal testing of all newly diagnosed patients with breast cancer, regardless of their age, personal or family history. The risk of experiencing a contralateral breast cancer (CBC) or ipsilateral recurrence, is well known. Such risk is highest with variants like BRCA1 and BRCA2, but less well-studied with other less common variants. The optimal local therapy for women with BRCA-associated breast cancer remains controversial, but tends to be aggressive and may involve bilateral mastectomies, which may not have any survival advantage. Additionally, surgical management of unaffected women, known to carry a pathogenic cancer-predisposing gene, may vary from surveillance to bilateral mastectomies, too. The oncological safety, and the higher satisfaction of unaffected women and patients with new surgical techniques, like the skin-sparing (SSM) and nipple-sparing (NSM) mastectomies, eased up the process of counselling. In this review, we address the oncological safety of less aggressive surgical options for both; patients and unaffected carriers.

Exploring the role of a multidisciplinary hereditary gynecologic oncology clinic in epithelial ovarian cancer risk-reducing surgical decision-making practices: A mixed-methods study

Individuals that have gynecologic reproductive organs with pathogenic variants in BRCA1 or BRCA2 ("BRCA-positive") have an increased risk of developing high-grade serous ovarian cancer (HGSOC). The majority of HGSOC develops in the fallopian tubes and later spreads to the ovaries and peritoneal cavity. Therefore, risk-reducing salpingo-oophorectomy (RRSO) is recommended for those who are BRCA-positive to preventatively remove their ovaries and fallopian tubes. The Hereditary Gynecology Clinic (HGC) is a provincial program in Winnipeg, Canada, that specifically targets care to the unique needs of such individuals through an interdisciplinary team of gynecological oncologists, menopause specialists, and registered nurses. A mixed-methods study design was used to explore the decision-making processes of these BRCA-positive individuals who have been recommended (or who completed) RRSO and experiences with healthcare providers at the HGC influenced this decision. Individuals who are BRCA-positive without a previous diagnosis of HGSOC and who had previously received genetic counselling were recruited from the HGC and the provincial cancer genetics program (Shared Health Program of Genetics & Metabolism). Forty-three people completed a survey and 15 participated in an in-depth interview about their experiences and decisions surrounding RRSO. Surveys were analyzed to compare scores on validated scales related to decision-making and cancer-related worry. Qualitative interviews were transcribed, coded, and analyzed using interpretive description. Participants described the complex decisions faced by those who are BRCA-positive, which are intertwined with life experiences and circumstances including age, marital status, and family disease history. Participants interpreted their HGSOC risk through a personalized "lens" of contextual factors that impacted perceptions about the practical and emotional implications of RRSO and the need for surgery. Mean scores on validated scales evaluating the HGC's impact on decisional outcomes and preparedness for decision-making about RRSO were not significant, indicating that the HGC played a supportive role, rather than helping with decision-making itself. Therefore, we present a novel framework that consolidates the various influences on decision-making and connects them to the psychological and practical implications of RRSO in the context of the HGC. Strategies for improving support, decisional outcomes, and the overall experiences of individuals who are BRCA-positive attending the HGC are also described.

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.

Prophylactic Radical Fimbriectomy with Delayed Oophorectomy in Women with a High Risk of Developing an Ovarian Carcinoma: Results of a Prospective National Pilot Study

Risk-reducing salpingo-oophorectomy is the gold standard for the prophylaxis of ovarian cancer in high-risk women. Due to significant adverse effects, 20-30% of women delay or refuse early oophorectomy. This prospective pilot study (NCT01608074) aimed to assess the efficacy of radical fimbriectomy followed by a delayed oophorectomy in preventing ovarian and pelvic invasive cancer (the primary endpoint) and to evaluate the safety of both procedures. The key eligibility criteria were pre-menopausal women ≥35 years with a high risk of ovarian cancer who refused a risk-reducing salpingo-oophorectomy. All the surgical specimens were subjected to the SEE-FIM protocol. From January 2012 to October 2014, 121 patients underwent RF, with 51 in an ambulatory setting. Occult neoplasia was found in two cases, with one tubal high-grade serous ovarian carcinoma. Two patients experienced grade 1 intraoperative complications. No early or delayed grade ≥3 post-operative complications occurred. After 7.3 years of median follow-up, no cases of pelvic invasive cancer have been noted. Three of the fifty-two patients developed de novo breast cancer. One BRCA1-mutated woman delivered twins safely. Twenty-five patients underwent menopause, including fifteen who had received chemotherapy for breast cancer, and twenty-three underwent menopause before the delayed oophorectomy, while two did not undergo a delayed oophorectomy at all. Overall, 46 women underwent a delayed oophorectomy. No abnormalities were found in any delayed oophorectomy specimens. Radical fimbriectomy followed by delayed oophorectomy appears to be a safe and well-tolerated risk-reducing approach, which avoids early menopause for patients with a high risk of breast and ovarian cancer.

Risk-Reducing Breast and Gynecological Surgery for BRCA Mutation Carriers: A Narrative Review

This narrative review aims to clarify the role of breast and gynecological risk-reduction surgery in BRCA mutation carriers. We examine the indications, contraindications, complications, technical aspects, timing, economic impact, ethical issues, and prognostic benefits of the most common prophylactic surgical options from the perspectives of a breast surgeon and a gynecologist. A comprehensive literature review was conducted using the PubMed/Medline, Scopus, and EMBASE databases. The databases were explored from their inceptions to August 2022. Three independent reviewers screened the items and selected those most relevant to this review's scope. BRCA1/2 mutation carriers are significantly more likely to develop breast, ovarian, and serous endometrial cancer. Because of the Angelina effect, there has been a significant increase in bilateral risk-reducing mastectomy (BRRM) since 2013. BRRM and risk-reducing salpingo-oophorectomy (RRSO) significantly reduce the risk of developing breast and ovarian cancer. RRSO has significant side effects, including an impact on fertility and early menopause (i.e., vasomotor symptoms, cardiovascular disease, osteoporosis, cognitive impairment, and sexual dysfunction). Hormonal therapy can help with these symptoms. Because of the lower risk of developing breast cancer in the residual mammary gland tissue after BRRM, estrogen-only treatments have an advantage over an estrogen/progesterone combined treatment. Risk-reducing hysterectomy allows for estrogen-only treatments and lowers the risk of endometrial cancer. Although prophylactic surgery reduces the cancer risk, it has disadvantages associated with early menopause. A multidisciplinary team must carefully inform the woman who chooses this path of the broad spectrum of implications, from cancer risk reduction to hormonal therapies.

Hereditary Women's Cancer: Management and Risk-Reducing Surgery

Hereditary women's syndromes due to inherited mutations result in an elevated risk of developing gynecological cancers over the lifetime of affected carriers. The BRCA 1 and 2 mutations, Lynch syndrome (LS), and mutations in rare hereditary syndromes increase this risk and require more effective management of these patients based on surveillance and prophylactic surgery. Patients need counseling regarding risk-reducing surgery (RRS) and the time required to perform it, considering the adverse effects of premenopausal surgery and the hormonal effect on quality of life, bone density, sexual activity, and cardiological and vascular diseases. Risk-reducing salpingo-oophorectomy (RRSO) is the gold standard for BRCA-mutated patients. An open question is that of endometrial cancer (EC) risk in patients with BRCA1/2 mutation to justify prophylactic hysterectomy during RRSO surgical procedures. RRS provides a 90-95% risk reduction for ovarian and breast cancer in women who are mutation carriers, but the role of prophylactic hysterectomy is underinvestigated in this setting of patients. In this review, we evaluate the management of the most common hereditary syndromes and the benefits of risk-reducing surgery, particularly exploring the role of prophylactic hysterectomy.

Cost-Effectiveness of Risk-Reducing Surgery for Breast and Ovarian Cancer Prevention: A Systematic Review

Policymakers require robust cost-effectiveness evidence of risk-reducing-surgery (RRS) for decision making on resource allocation for breast cancer (BC)/ovarian cancer (OC)/endometrial cancer (EC) prevention. We aimed to summarise published data on the cost-effectiveness of risk-reducing mastectomy (RRM)/risk-reducing salpingo-oophorectomy (RRSO)/risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) for BC/OC prevention in intermediate/high-risk populations; hysterectomy and bilateral salpingo-oophorectomy (BSO) in Lynch syndrome women; and opportunistic bilateral salpingectomy (OBS) for OC prevention in baseline-risk populations. Major databases were searched until December 2021 following a prospective protocol (PROSPERO-CRD42022338008). Data were qualitatively synthesised following a PICO framework. Twenty two studies were included, with a reporting quality varying from 53.6% to 82.1% of the items scored in the CHEERS checklist. The incremental cost-effectiveness ratio/incremental cost-utility ratio and cost thresholds were inflated and converted to US$2020, using the original currency consumer price index (CPI) and purchasing power parities (PPP), for comparison. Eight studies concluded that RRM and/or RRSO were cost-effective compared to surveillance/no surgery for BRCA1/2, while RRESDO was cost-effective compared to RRSO in one study. Three studies found that hysterectomy with BSO was cost-effective compared to surveillance in Lynch syndrome women. Two studies showed that RRSO was also cost-effective at ≥4%/≥5% lifetime OC risk for pre-/post-menopausal women, respectively. Seven studies demonstrated the cost-effectiveness of OBS at hysterectomy (n = 4), laparoscopic sterilisation (n = 4) or caesarean section (n = 2). This systematic review confirms that RRS is cost-effective, while the results are context-specific, given the diversity in the target populations, health systems and model assumptions, and sensitive to the disutility, age and uptake rates associated with RRS. Additionally, RRESDO/OBS were sensitive to the uncertainty concerning the effect sizes in terms of the OC-risk reduction and long-term health impact. Our findings are relevant for policymakers/service providers and the design of future research studies.

Pathologic Findings at Risk Reducing Surgery in BRCA and Non-BRCA Mutation Carriers: A Single-Center Experience

Risk-reducing surgery (RRS) is recommended in BRCA-mutated carriers because of their increased risk of developing ovarian cancer, while its role is still discussed for women harboring mutations in non-BRCA homologous repair genes. The aim of this study was to retrospectively evaluate the occurrence of pathological findings in a high-risk population undergoing RRS in San Matteo Hospital, Pavia between 2012 and 2022, and correlate their genetic and clinical outcomes, comparing them with a control group. The final cohort of 190 patients included 85 BRCA1, 63 BRCA2, 11 CHEK2, 7 PALB2, 4 ATM, 1 ERCC5, 1 RAD51C, 1 CDH1, 1 MEN1, 1 MLH1 gene mutation carriers and 15 patients with no known mutation but with strong familial risk. Occult invasive serous carcinoma (HGSC) and serous tubal intraepithelial carcinoma (STIC) were diagnosed in 12 (6.3%) women, all of them BRCA carriers. No neoplastic lesion was diagnosed in the non-BRCA group, in women with familial risk, or in the control group. Oral contraceptive use and age ≤45 at surgery were both found to be favorable factors. While p53 signature and serous tubal intraepithelial lesion (STIL) were also seen in the control group and in non-BRCA carriers, STIC and HGSC were only found in BRCA1/2 mutation carriers.

Hereditary Ovarian Cancer: Towards a Cost-Effective Prevention Strategy

Ovarian cancer (OC) is the most lethal gynaecological malignancy. The search for a widely affordable and accessible screening strategy to reduce mortality from OC is still ongoing. This coupled with the late-stage presentation and poor prognosis harbours significant health-economic implications. OC is also the most heritable of all cancers, with an estimated 25% of cases having a hereditary predisposition. Advancements in technology have detected multiple mutations, with the majority affecting the BRCA1 and/or BRCA2 genes. Women with BRCA mutations are at a significantly increased lifetime risk of developing OC, often presenting with a high-grade serous pathology, which is associated with higher mortality due to its aggressive characteristic. Therefore, a targeted, cost-effective approach to prevention is paramount to improve clinical outcomes and mortality. Current guidelines offer multiple preventive strategies for individuals with hereditary OC (HOC), including genetic counselling to identify the high-risk women and risk-reducing interventions (RRI), such as surgical management or chemoprophylaxis through contraceptive medications. Evidence for sporadic OC is abundant as compared to the existing dearth in the hereditary subgroup. Hence, our review article narrates an overview of HOC and explores the RRI developed over the years. It attempts to compare the cost effectiveness of these strategies with women of the general population in order to answer the crucial question: what is the most prudent clinically and economically effective strategy for prevention amongst high-risk women?

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.

Racial and ethnic differences in the adoption of opportunistic salpingectomy for ovarian cancer prevention in the United States

BACKGROUND

Clinicians in the United States have rapidly adopted opportunistic salpingectomy for ovarian cancer prevention. However, little is known about racial and ethnic differences in opportunistic salpingectomy adoption. Surgical innovations in gynecology may be adopted differentially across racial and ethnic groups, exacerbating current disparities in quality of care.

OBJECTIVE

This study aimed to evaluate racial and ethnic differences in opportunistic salpingectomy adoption across inpatient and outpatient settings and assess the effect of national guidelines supporting opportunistic salpingectomy use on these differences.

STUDY DESIGN

A sample of 650,905 women aged 18 to 50 years undergoing hysterectomy with ovarian conservation or surgical sterilization from 2011 to 2018 was identified using the Premier Healthcare Database, an all-payer hospital administrative database, including more than 700 hospitals across the United States. The association between race and ethnicity and opportunistic salpingectomy use was examined using multivariable-adjusted mixed-effects log-binomial regression models accounting for hospital-level clustering. Models included race and ethnicity by year of surgery (2011-2013 [before guideline] and 2014-2018 [after guideline]) interaction term to test whether racial and ethnic differences in opportunistic salpingectomy adoption changed with the release of national guidelines supporting opportunistic salpingectomy use.

RESULTS

From 2011 to 2018, 82,792 women underwent hysterectomy and opportunistic salpingectomy (non-Hispanic White, 60.3%; non-Hispanic Black, 18.8%; Hispanic, 12.2%; non-Hispanic other race, 8.7%) and 23,398 women underwent opportunistic salpingectomy for sterilization (non-Hispanic White, 64.7%; non-Hispanic Black, 10.8%; Hispanic, 16.7%; non-Hispanic other race, 7.8%). The proportion of hysterectomy procedures involving an opportunistic salpingectomy increased from 6.3% in 2011 to 59.7% in 2018 (9.5-fold increase), and the proportion of sterilization procedures involving an opportunistic salpingectomy increased from 0.7% in 2011 to 19.4% in 2018 (27.7-fold increase). In multivariable-adjusted models, non-Hispanic Black (risk ratio, 0.94; 95% confidence interval, 0.92-0.97), Hispanic (risk ratio, 0.98; 95% confidence interval, 0.95-1.00), and non-Hispanic other race women (risk ratio, 0.93; 95% confidence interval, 0.90-0.96) were less likely to undergo hysterectomy and opportunistic salpingectomy than non-Hispanic White women. A significant interaction between race and ethnicity and year of surgery was noted in non-Hispanic Black compared with non-Hispanic White women (P<.001), with a reduction in differences in hysterectomy and opportunistic salpingectomy use after national guideline release (risk ratio_2011-2013, 0.80 [95% confidence interval, 0.73-0.88]; risk ratio_2014-2018, 0.98 [95% confidence interval, 0.95-1.01]). Moreover, non-Hispanic Black women were less likely to undergo an opportunistic salpingectomy for sterilization than non-Hispanic White women (risk ratio, 0.91; 95% confidence interval, 0.88-0.95), with no difference by year of surgery (P=.62). Stratified analyses by hysterectomy route and age at surgery revealed similar results.

CONCLUSION

Although opportunistic salpingectomy for ovarian cancer prevention has been rapidly adopted in the United States, our findings suggested that its adoption has not been equitable across racial and ethnic groups. Non-Hispanic Black, Hispanic, and non-Hispanic other race women were less likely to undergo opportunistic salpingectomy than non-Hispanic White women even after adjusting for sociodemographic, clinical, procedural, hospital, and provider characteristics. These differences persisted after the release of national guidelines supporting opportunistic salpingectomy use. Future research should focus on understanding the reasons for these differences to inform interventions that promote equity in opportunistic salpingectomy use.

Impact of BRCA Status on Reproductive Decision-Making and Self-Concept: A Mixed-Methods Study Informing the Development of Tailored Interventions

This mixed-methods study sought to deepen our understanding of self-concept and experiences in balancing cancer risk/reproductive decisions after learning of BRCA+ status. First, a quantitative survey of BRCA+ women (n = 505) examined the childbearing status, risk-reducing surgery, and self-concept. At the time of testing, 307/505 (60.8%) women were of reproductive age (<40 years-old), 340/505 (67.3%) had children, and 317/505 (62.8%) had undergone risk-reducing surgery. A younger age at the time of the testing was significantly associated with the decision to have children after learning BRCA+ status or undergoing risk-reducing surgery (p < 0.001). Compared to older women, BRCA+ women of reproductive age, exhibited a more negative self-concept with significantly higher vulnerability ratings (p < 0.01). Women with a cancer diagnosis exhibited a more negative mastery ratings and worse vulnerability ratings (p < 0.01) than women without a cancer history. Compared to childless counterparts, significantly higher vulnerability ratings were observed among BRCA+ women who had children before learning their BRCA status and/or undergoing risk-reducing surgery (p < 0.001). Subsequently, a subset of women (n = 40) provided in-depth interviews to explore their experiences in decision-making. The interviews provided insights into the effects of BRCA status on decisions regarding relationships, childbearing, cancer risk management, and communicating BRCA risk to children. Integrating quantitative and qualitative findings identifies targets for tailored interventions to enhance precision health for BRCA+ women of reproductive age.

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.

Uptake and Predictors of Opportunistic Salpingectomy for Ovarian Cancer Risk Reduction in the United States

Evidence suggesting that high-grade serous ovarian cancers originate in the fallopian tubes has led to the emergence of opportunistic salpingectomy (OS) as an approach to reduce ovarian-cancer risk. In the U.S., some national societies now recommend OS in place of tubal ligation for sterilization or during a benign hysterectomy in average-risk women. However, limited data exist on the dissemination of OS in clinical practice. We examined the uptake and predictors of OS in a nationwide sample of inpatient and outpatient claims (N = 48,231,235) from 2010 to 2017. Incidence rates of OS were calculated, and an interrupted time-series analysis was used to quantify changes in rates before (2010-2013) and after (2015-2017) national guideline release. Predictors of OS use were examined using Poisson regression. From 2010 to 2017, the age-adjusted incidence rate of OS for sterilization and OS during hysterectomy increased 17.8-fold [95% confidence interval (CI), 16.2-19.5] and 7.6-fold (95% CI, 5.5-10.4), respectively. The rapid increase (age-adjusted increase in quarterly rates of between 109% and 250%) coincided with the time of national guideline release. In multivariable-adjusted analyses, OS use was more common in young women and varied significantly by geographic region, rurality, family history/genetic susceptibility, surgical indication, inpatient/outpatient setting, and underlying comorbidities. Similar differences in OS uptake were noted in analyses limited to women with a family history/genetic susceptibility to breast/ovarian cancer. Our results highlight significant differences in OS uptake in both high- and average-risk women. Defining subsets of women who would benefit most from OS and identifying barriers to equitable OS uptake is needed. PREVENTION RELEVANCE: Opportunistic salpingectomy for ovarian-cancer risk reduction has been rapidly adopted in the U.S., with significant variation in uptake by demographic and clinical factors. Studies examining barriers to opportunistic salpingectomy access and the long-term effectiveness and potential adverse effects of opportunistic salpingectomy are needed.

Uptake and timing of risk-reducing salpingo-oophorectomy among patients with BRCA1 and BRCA2 mutations

BACKGROUND

In women with BRCA mutations, risk-reducing bilateral salpingo-oophorectomy has been shown to decrease gynecologic cancer-specific and overall mortality. The National Comprehensive Cancer Network recommends that patients with BRCA mutations undergo risk-reducing bilateral salpingo-oophorectomy between the ages of 35 and 40 years for BRCA1 mutation carriers and between the ages of 40 and 45 years for BRCA2 mutation carriers or after childbearing is complete. Currently, uptake and timing of risk-reducing bilateral salpingo-oophorectomy and reasons for delays in risk-reducing bilateral salpingo-oophorectomy are not well understood.

OBJECTIVE

We sought to evaluate uptake and timing of risk-reducing bilateral salpingo-oophorectomy among women with BRCA1 and BRCA2 mutations concerning the National Comprehensive Cancer Network guidelines and reasons for delays in risk-reducing bilateral salpingo-oophorectomy.

STUDY DESIGN

In this retrospective chart review, we identified women with BRCA1 and BRCA2 mutations who discussed risk-reducing bilateral salpingo-oophorectomy with a provider between 2012 and 2021. Uptake of risk-reducing bilateral salpingo-oophorectomy was documented, and patients were classified as having timely or delay in risk-reducing bilateral salpingo-oophorectomy based on the National Comprehensive Cancer Network guidelines. For those with delay in risk-reducing bilateral salpingo-oophorectomy, reasons cited for delay were collected. Comparative statistical analyses were performed to evaluate characteristics of those with timely vs delayed risk-reducing bilateral salpingo-oophorectomy. A multivariable logistic regression model was used to evaluate the associations among factors related to timing of risk-reducing bilateral salpingo-oophorectomy.

RESULTS

We identified 638 BRCA1 and BRCA2 mutation carriers seen between 2012 and 2021. Of these patients, 306 (48.0%) had undergone risk-reducing bilateral salpingo-oophorectomy and 332 (52.0%) had not. When evaluating the timing of risk-reducing bilateral salpingo-oophorectomy, 136 (21.3%) underwent timely risk-reducing bilateral salpingo-oophorectomy, 239 (37.5%) had delays in risk-reducing bilateral salpingo-oophorectomy, and 263 (41.2%) had not undergone risk-reducing bilateral salpingo-oophorectomy but were younger than the National Comprehensive Cancer Network age guidelines; therefore, they were neither timely nor delayed. Patients with delay in risk-reducing bilateral salpingo-oophorectomy were significantly older at the time of genetic testing than those with timely risk-reducing bilateral salpingo-oophorectomy (mean, 49.8 vs 36.3 years; P<.001). Of the 306 patients who underwent risk-reducing bilateral salpingo-oophorectomy, those with delayed risk-reducing bilateral salpingo-oophorectomy had a significantly shorter interval between BRCA identification and risk-reducing bilateral salpingo-oophorectomy than those with timely risk-reducing bilateral salpingo-oophorectomy (median, 8.7 vs 17.6 months; P<.001). Patients with delay in risk-reducing bilateral salpingo-oophorectomy were more likely to have a personal history of cancer than those with timely risk-reducing bilateral salpingo-oophorectomy (49.8% vs 37.5%; P=.028). Of the 239 women with delay in risk-reducing bilateral salpingo-oophorectomy, 188 (78.7%) had delayed BRCA mutation identification, 29 (12.1%) had menopausal concerns, 17 (7.1%) had ongoing cancer treatment, 12 (5.0%) had coordination with breast surgery, 20 (8.4%) had miscellaneous reasons, and 19 (7.9%) had no reason documented. In the multivariate model, older age at BRCA diagnosis (odds ratio, 0.73; 95% confidence interval, 0.68-0.78; P<.001) was significantly associated with delayed risk-reducing bilateral salpingo-oophorectomy timing; those with BRCA2 mutation type were 7.54 times as likely to have timely risk-reducing bilateral salpingo-oophorectomy than BRCA1 mutation carriers (odds ratio, 7.54; 95% confidence, 3.70-16.42; P<.001).

CONCLUSION

Nearly 38% of BRCA1 and BRCA2 mutation carriers undergo or have yet to undergo risk-reducing bilateral salpingo-oophorectomy over the recommended National Comprehensive Cancer Network age. The most common reason for the delay in risk-reducing bilateral salpingo-oophorectomy was delayed identification of BRCA mutation, noted in 79% of patients with delayed risk-reducing bilateral salpingo-oophorectomy. Timely genetic testing for eligible patients can increase appropriately timed risk-reducing bilateral salpingo-oophorectomy for the prevention of ovarian cancer and reduction of mortality in BRCA mutation carriers.

Role of Routine Peritoneal Biopsies During Risk Reducing Salpingo-Oophorectomy (RRSO)

Objective The objective of this retrospective study was to assess the role of routine peritoneal biopsies during risk reducing salpingo-oophorectomy (RRSO).

Methods Data of 204 women who underwent RRSO between January 1, 2014 and February 20, 2020 at Charité – Universitätsmedizin Berlin, Campus Mitte were retrospectively analyzed. RRSO was done according to the standard operating procedures of the German Consortium Hereditary Breast and Ovarian Cancer (GC-HBOC) with peritoneal washing and several peritoneal biopsies. Specimen collected during RRSO were analyzed using the protocol for Sectioning and Extensively Examining the FIMbria (SEE-FIM). Perioperative complications were classified using the Clavien-Dindo-Classification.

Results 147 women who underwent RRSO had peritoneal biopsies and pelvic washing, 44 women had none of that. 123 patients (64.4%) carried a pathologic variant in gBRCA1 , 53 (27.7%) carried a pathologic variant in gBRCA2 . Histopathological evaluation identified four patients (2.1%) with pathological findings. Neither peritoneal biopsies nor pelvic washings revealed additional information after histological examination. There was no statistically significant difference in complication rate between the two groups. The mean surgery time for RRSO without peritoneal biopsies was 64.3 minutes compared to 77.8 minutes with peritoneal biopsies. That shows a statistically significant prolongation of 16% (13.5 minutes, p = 0.0383).

Conclusions The routine use of peritoneal biopsies during RRSO does not improve detection of occult ovarian cancer or STIC but prolongs the operation time significantly. By omitting peritoneal biopsies in RRSO not only perioperative risks are diminished but also costs could be reduced by shortening of surgery time as well as decreased number of pathological samples.

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.

Salpingectomy vs tubal ligation for sterilization: a systematic review and meta-analysis

OBJECTIVE

After strong evidence and major organizations recommending salpingectomy over tubal ligation, we sought to perform a systematic review and meta-analysis comparing the intraoperative attributes and complication rates associated with these 2 procedures.

DATA SOURCES

We searched PubMed, the Cochrane Library, Embase, and clinical trials registries without time or language restrictions. The search was conducted in February 2020. Database searches revealed 74 potential studies, of which 11 were examined at the full-text level. Of these, 6 studies were included in the qualitative analysis and 5 studies were included in the meta-analysis.

STUDY ELIGIBILITY CRITERIA

We included randomized controlled trials comparing salpingectomy with tubal ligation in women seeking sterilization. We included studies that also had at least 1 outcome listed in the population/patient problem, intervention, comparison, outcome, and time. Articles were excluded if they did not meet the inclusion criteria or if data were not reported and the authors did not respond to inquiries.

STUDY APPRAISAL AND SYNTHESIS METHODS

Abstracts and full-text articles were assessed by 2 authors independently using the blinded coding assignment function or EPPI-Reviewer 4. Conflicting selections were resolved by consensus. The quality of included studies was determined using the Cochrane Collaboration tool for assessing the risk of bias in randomized trials. Two authors independently assessed the risk of bias for each study; disagreements were resolved by consensus.

RESULTS

There were few differences between the procedures, with no differences in most important clinical outcomes (antimüllerian hormone, blood loss, length of hospital stay, pre- or postoperative complications, or wound infections). A single study reported a reduced rate of pregnancies with salpingectomy (risk ratio, 0.22; 95% confidence interval, 0.05-1.02), but this did not reach statistical significance (P=.05).

CONCLUSION

We conclude from these data that salpingectomy is as safe and efficacious as tubal ligation for sterilization and may be preferred, where appropriate, to reduce the risk of ovarian cancer.

Post-mastectomy surveillance of BRCA1/BRCA2 mutation carriers: Outcomes from a specialized clinic for high-risk breast cancer patients

Female BRCA1/BRCA2 mutation carriers may elect bilateral risk-reducing mastectomy. There is a paucity of data on yield of imaging surveillance after risk-reducing mastectomy. This retrospective study focused on female BRCA1/BRCA2 mutation carriers who underwent bilateral mastectomy either as primary preventative, or as secondary preventative, after breast cancer diagnosis. All participants underwent breast imaging at 6- to 12-month intervals after mastectomy. Data on subsequent breast cancer diagnosis and timing were collected and compared between the groups. Overall, 184 female mutation carriers (134 BRCA1, 45 BRCA2, 5 both BRCA genes) underwent bilateral mastectomy after initial breast cancer diagnosis, between April 1, 2009 and August 31, 2018. During a mean follow-up of 6.2 ± 4.2 years, 13 (7.06%) were diagnosed with breast cancer; 12 ipsilateral (range: 0.4-28.8 years) and 1 contralateral breast cancer, 15.9 years after surgery. On the contrary, among asymptomatic BRCA1 (n = 40) and BRCA2 (n = 13) mutation carriers who underwent primary risk-reducing mastectomy (mean age at surgery 39.5 ± 8.4 years); none has developed breast cancer after a mean follow-up of 5.4 ± 3.4 years. BRCA1/BRCA2 mutation carriers with prior disease who underwent risk-reducing mastectomy after breast cancer diagnosis are still prone for developing ipsi or contralateral breast cancer, and therefore may benefit from continues clinical and imaging surveillance, unlike BRCA1/BRCA2 mutation carriers who undergo primary preventative bilateral mastectomy.

Gynecological Surveillance and Surgery Outcomes in Dutch Lynch Syndrome Carriers

Simple Summary

Female Lynch syndrome (LS) carriers have an increased risk to develop endometrial and ovarian cancer. In the Netherlands, carriers are therefore advised annual gynecological surveillance and eventually, risk-reducing surgery. Global gynecological LS surveillance guidelines are scarce and based on limited evidence. These are, however, warranted to offer accurate surveillance. To provide more insight into surveillance outcomes, this study assessed outcomes of gynecological surveillance and risk-reducing surgery in 164 LS carriers diagnosed in our center, with a median follow-up of 5.6 years per carrier. Although most surveillance visits happened within an advised timeframe, we observed large variability in how gynecological surveillance visits were performed. This finding stresses the need for development of clear and evidence-based guidelines. Endometrial cancers identified at surveillance were all found in early stage, mostly symptomatic, questioning surveillance benefit. Large, prospective studies should assess to what extent current LS surveillance programs contribute to early detection of gynecological tumors.

Abstract

Lynch syndrome (LS) is caused by pathogenic germline variants in DNA mismatch repair (MMR) genes, predisposing female carriers for endometrial cancer (EC) and ovarian cancer (OC). Since gynecological LS surveillance guidelines are based on little evidence, we assessed its outcomes. Data regarding gynecological tumors, surveillance, and (risk-reducing) surgery were collected from female LS carriers diagnosed in our center since 1993. Of 505 female carriers, 104 had a gynecological malignancy prior to genetic LS diagnosis. Of 264 carriers eligible for gynecological management, 164 carriers gave informed consent and had available surveillance data: 38 MLH1, 25 MSH2, 82 MSH6, and 19 PMS2 carriers (median follow-up 5.6 years). Surveillance intervals were within advised time in >80%. Transvaginal ultrasound, endometrial sampling, and CA125 measurements were performed in 76.8%, 35.9%, and 40.6%, respectively. Four symptomatic ECs, one symptomatic OC, and one asymptomatic EC were diagnosed. Endometrial hyperplasia was found in eight carriers, of whom three were symptomatic. Risk-reducing surgery was performed in 73 (45.5%) carriers (median age 51 years), revealing two asymptomatic ECs. All ECs were diagnosed in FIGO I. Gynecological management in LS carriers varied largely, stressing the need for uniform, evidence-based guidelines. Most ECs presented early and symptomatically, questioning the surveillance benefit in its current form.

Challenges and Considerations on Risk-Reducing Surgery in BRCA1/2 Patients with Advanced Breast Cancer

Cancer survivors harboring inherited pathogenic variants in the breast cancer (BC) susceptibility genes BRCA1 or BRCA2 are at increased risk of ovarian cancer (OC) and also of contralateral BC. For these women, risk-reducing surgery (RRS) may contribute to risk management. However, women with locally advanced or metastatic breast cancer (ABC) were excluded from clinical trials evaluating the benefit of these procedures in the BRCA1/2 carriers, and thus, current guidelines do not recommend RRS in this specific setting. Although ABC remains an incurable disease, recent advances in treatment have led to increased survival, which, together with improvement in RRS techniques, raise questions about the potential role of RRS in the management of BRCA1/2 ABC patients. When should RRS be discussed as an option for BRCA1/2 patients diagnosed with ABC? To address this issue, we report two clinical cases that reflect new challenges in routine oncology practice. Team experience and patient motivations may shape multidisciplinary decisions in the absence of evidence-based data. A wise rationale may be the analysis of the competing risks of death by a previous ABC against risk of death by a secondary BC or OC, tailored to patient preferences.

A mismatch in care: results of a United Kingdom-wide patient and clinician survey of gynaecological services for women with Lynch syndrome

OBJECTIVE

To describe the current testing practice, referral pathways and gynaecological services available to women with Lynch syndrome (LS) in the UK.

DESIGN

Cross-sectional nationwide survey of gynaecological oncologists and women with LS.

SETTING

United Kingdom.

METHODS

Gynaecological oncologists were contacted directly. Women with LS were identified from national and regional clinical databases and the patient support group, Lynch syndrome UK.

MAIN OUTCOME MEASURES

Gynaecological oncologists were asked to report rates of LS testing and current practice regarding risk-reducing strategies and gynaecological surveillance for women with LS. Women with LS were asked to describe their experiences of gynaecological care.

RESULTS

In total, 41 gynaecological oncologists and 298 women with LS responded to the survey. Of the gynaecological oncologists surveyed, 37% were unfamiliar with any clinical guidelines for the management of LS. Only 29% of gynaecological oncologists supported universal testing of endometrial cancer for LS; one centre routinely performed such testing. In all, 83% said they perform risk-reducing gynaecological surgery and 43% were aware of a local gynaecological surveillance service for women with LS. Of women with LS, most had undergone a hysterectomy (n = 191/64.1%), most frequently to reduce their gynaecological cancer risk (n = 86/45%). A total of 10% were initially referred for LS testing by their gynaecologist and 55% of those eligible regularly attended gynaecological surveillance; however, 62% wanted more regular surveillance. Regional variation was evident across all standards of care.

CONCLUSIONS

There is widespread variation in the services offered to women with LS in the UK. As a community, gynaecological oncologists should move towards a nationally agreed provision of services.

TWEETABLE ABSTRACT

A mismatch in care for mismatch repair. Survey finds significant variation in gynaecological care for #Lynchsyndrome in the UK.

Risk-Reducing Gynecological Surgery in Lynch Syndrome: Results of an International Survey from the Prospective Lynch Syndrome Database

Purpose: To survey risk-reducing hysterectomy and bilateral salpingo-oophorectomy (BSO) practice and advice regarding hormone replacement therapy (HRT) in women with Lynch syndrome. Methods: We conducted a survey in 31 contributing centers from the Prospective Lynch Syndrome Database (PLSD), which incorporates 18 countries worldwide. The survey covered local policies for risk-reducing hysterectomy and BSO in Lynch syndrome, the timing when these measures are offered, the involvement of stakeholders and advice regarding HRT. Results: Risk-reducing hysterectomy and BSO are offered to path_MLH1 and path_MSH2 carriers in 20/21 (95%) contributing centers, to path_MSH6 carriers in 19/21 (91%) and to path_PMS2 carriers in 14/21 (67%). Regarding the involvement of stakeholders, there is global agreement (~90%) that risk-reducing surgery should be offered to women, and that this discussion may involve gynecologists, genetic counselors and/or medical geneticists. Prescription of estrogen-only HRT is offered by 15/21 (71%) centers to women of variable age range (35–55 years). Conclusions: Most centers offer risk-reducing gynecological surgery to carriers of path_MLH1, path_MSH2 and path_MSH6 variants but less so for path_PMS2 carriers. There is wide variation in how, when and to whom this is offered. The Manchester International Consensus Group developed recommendations to harmonize clinical practice across centers, but there is a clear need for more research.

Minilaparoscopic single-site bilateral salpingo-oophorectomy: a scarless prophylactic procedure

We present the first case of minilaparoscopic single-site bilateral salpingo-oophorectomy (BSO) performed as a risk-reducing procedure in a 39-year-old woman presenting with BRCA-1 mutation. Surgery was performed using only minilaparoscopic instruments inserted alternatively through two 3-mm umbilical trocars placed one next to the other. Following the BSO, specimens were retrieved within an endobag through the posterior vaginal fornix. No intraoperative or postoperative complications occurred. The patient was discharged home on the day of surgery. Thirty-day postoperative clinical evaluation was uneventful. In selected patients, the minilaparoscopic single-site approach might represent an alternative technique to minimize surgical trauma and morbidity in patients undergoing risk-reducing BSO.

Bilateral salpingectomy versus bilateral partial salpingectomy during cesarean delivery

Objective

To compare surgical outcomes in patients undergoing bilateral salpingectomy (salpingectomy group) with those who had partial salpingectomy (partial salpingectomy group) during cesarean delivery.

Materials and methods

A chart review from July 2015 to November 2016 was performed. We included women who had sterilization during cesarean delivery. We excluded sterilization by occlusive methods. Our primary outcomes were total operative time and a composite score of transfusion rate, internal organ injury, hospital readmission, and endometritis. Secondary outcomes included menstrual abnormalities, pelvic pain, quality of life assessment, and regrets rate. We compared these outcomes between women in the salpingectomy and partial salpingectomy groups. Chi-squared, Fisher’s exact, t-test, and Mann–Whitney U were utilized for statistical analysis where appropriate. A P<0.05 was considered significant.

Results

We included a total of 160 pregnancies. Of these, 41 were in the salpingectomy and 119 in the partial salpingectomy group. The median total operative time was longer for the salpingectomy group (62 [IQR 54, 71] vs 60 minutes [IQR 46, 72]; P=0.03). The composite of surgical complications (19.5% vs 12.6%; P=0.28) was not significantly different between our study groups. Menstrual irregularities (P≥0.99), quality of life (P≥0.99), dyspareunia (P≥0.99), dysmenorrhea (P=0.36), and regrets (P≥0.99) were not different between groups.

Conclusion

Salpingectomy during cesarean delivery increased the median operative time by 2 minutes and may not be associated with an increased risk of surgical complications. We acknowledge the need for larger multi-center trials to corroborate our outcomes.

Recommendations and Choices for BRCA Mutation Carriers at Risk for Ovarian Cancer: A Complicated Decision

Current ovarian cancer screening guidelines in high-risk women vary according to different organizations. Risk reducing surgery remains the gold standard for definitive treatment in BRCA mutation carriers, but research advancements have created more short-term options for patients to consider. The decisions involved in how a woman manages her BRCA mutation status can cause a great deal of stress and worry due to the imperfect therapy options. The goal of this review was to critically analyze the screening recommendations and alternative options for high-risk ovarian cancer patients and evaluate how these discrepancies and choices affect a woman’s management decisions.

Uptake of risk-reducing surgery in BRCA gene carriers in Wales, UK

Women who inherit a mutated copy of the BRCA gene have a higher lifetime risk of developing breast cancer. No large epidemiological studies exist looking at BRCA mutation carriers in UK populations. All patients with BRCA1/BRCA2 mutation identified between 1995 and 2015 were included. Individuals were identified from a prospectively gathered data base. Genetics case-notes were obtained and retrospective analysis performed. 581 female BRCA mutation carriers were identified with a median age of 34 (18-81) at the time of testing. Of the 301 women who underwent diagnostic testing (symptomatic) 246 had been diagnosed with breast cancer, 89 with ovarian cancer and 37 had both at time of testing. Median age at diagnostic test was 51 (25-81). 33% of women underwent risk-reducing mastectomies (RRM); median age at surgery 45. This compares with 37% of women in this diagnostic group who underwent Risk-reducing bilateral salpingo-oopherectomies (RRBSO) at a median age of 46. Two hundred and eighty women underwent predictive testing (family history, asymptomatic), median age 36 (18-81). 34% of women in this predictive group underwent RRM, median age 37. There was a 29% uptake of RRBSO (median age 44 years). Fifteen women (5%) developed breast cancer after being tested; none of these had undergone RRS. This unique study of all BRCA mutation carriers in Wales shows considerable variation in uptake of RRS. The decision to undergo RRS is complex and involves a number of factors, including a woman's age and life stage. As BRCA testing becomes more frequent and more gene mutation carriers are identified there will be significant implications for service allocation, screening demands, and provision of risk-reducing surgery for this high-risk patient group.

Experiencing the cancer of a loved one influences decision-making for breast cancer prevention

Prior research demonstrates that family history influences breast cancer prevention decisions among healthy women at elevated risk of the disease. Drawing on in-depth interviews with 50 African American and White women, this study reveals an important psychological mechanism of this relationship: exposure to cancer among loved ones. Four distinct categories of cancer exposure (Abstract, Generalized, Practical, and Traumatic), distinguished by the characteristics of women's experiences with cancer among family members and close friends, are associated with differences in knowledge and decisions about breast cancer prevention options. Racial differences and distinct experiences among those with BRCA mutations are also discussed.

Physicians' Perspectives and Practice Patterns Toward Opportunistic Salpingectomy in High- and Low-Risk Women

BACKGROUND

Opportunistic bilateral salpingectomy (OBS) has been proposed as an ovarian cancer risk-reducing strategy.

METHODS

A survey was emailed to 300 members of the American College of Obstetricians and Gynecologists.

RESULTS

125 (42%) surveys were returned: 60% female, 88% generalists, 67% private practice. Only 36% correctly identified the lifetime risk of ovarian cancer, only 23% understood the risk-reducing benefit of bilateral salpingo-oophorectomy. 75% perform salpingectomy during hysterectomy, 26-53% use for sterilization depending on approach. Concerns were increased operative time and complications. For BRCA mutations, 64% recommend BSO, 12% recommend a two-step risk-reducing strategy, and 14% refer to gynecologic oncology.

CONCLUSIONS

We identified broad support and factors limiting willingness to perform OBS.

Conservative mastectomies for breast cancer and risk-reducing surgery: the Memorial Sloan Kettering Cancer Center experience

Demand for conservative mastectomies continues to increase as more patients choose to undergo breast reconstruction, often with simultaneous contralateral prophylactic mastectomy (CPM). In addition, the increasing use of risk-reducing surgery in high-risk groups has contributed to the increased use of these techniques. We have reviewed the indications and outcomes of a large group of patients undergoing nipple-sparing mastectomy (NSM) at this institution. In total, 728 nipple-sparing mastectomies (NSMs) were performed in 413 patients between 2000 and 2013, for treatment of breast cancer (n=269) or risk reduction (n=459). Of 728 NSMs performed, 177 (24.3%) were in patients known to have a BRCA1 or BRCA2 germline mutation, or a genetic variant of uncertain significance. There was an incidental finding of ductal carcinoma in situ (DCIS) or invasive carcinoma in 22 (4.8%) and 8 (1.7%) of 459 prophylactic NSMs, respectively. In addition, unexpected invasive carcinoma was found in 17 of 98 therapeutic NSMs (17.3%) performed for DCIS. At median follow-up of 49 months, there were no known cases of local recurrence and only one case of regional recurrence. Immediate breast reconstruction was performed in 409 patients, most of whom underwent tissue expander/implant based procedures (n=401). Although 273 breasts (37.5%) had some evidence of skin desquamation at follow-up, most resolved spontaneously with 47 breasts (6.5%) requiring debridement. Other complications included hematoma in seven breasts (1%) and wound infection in 31 breasts (4.3%). Expander/implant removal was required in 20 cases (2.8%). The nipple-areola complex (NAC) was subsequently excised in 10 of 728 breasts (1.4%) due to oncologic concerns following assessment of retroareolar tissue. NSM was successful in most patients with an acceptable complication rate and in few patients subsequently undergoing removal of the NAC. Patients requiring mastectomy for breast cancer or risk reduction may now benefit from conservative mastectomy techniques such as NSM, resulting in improved cosmesis and, possibly, a reduced psychological impact.

Personalized assessment and management of women at risk for breast cancer in North America

Many women at increased risk for breast cancer would benefit from referral for genetic testing, enhanced screening, preventive therapy or risk-reducing surgery. We present a visual model and a step-wise approach to assist with a personalized risk stratification and management of these women. We present current recommendations with respect to lifestyle behaviors and mammographic screening, and we review the current evidence regarding enhanced screening and risk-reducing therapies. We discuss the usefulness of three risk-assessment tools in determining whether a woman qualifies for genetic testing, enhanced screening or preventive therapy and present four cases to demonstrate the usefulness of this approach in the clinical setting.

Risk-reducing surgery in hereditary gynecological cancer: Clinical applications in Lynch syndrome and hereditary breast and ovarian cancer

Risk-reducing surgery (RRS) is defined as a prophylactic approach with removal of organs at high risk of developing cancer, which is performed in cases without lesions or absence of clinically significant lesions. Hereditary gynecological cancers for which RRS is performed include hereditary breast and ovarian cancer (HBOC) and Lynch syndrome. For HBOC, RRS in the United States (US) is recommended for women with mutations in the breast cancer susceptibility (BRCA)1 and BRCA2 genes and bilateral salpingo-oophorectomy (BSO) is generally performed. This procedure may reduce the risk of breast, ovarian, Fallopian tube and primary peritoneal cancer, although ovarian deficiency symptoms occur postoperatively. For Lynch syndrome, RRS in the US is considered for postmenopausal women or for women who do not desire to bear children and BSO and hysterectomy are usually performed. This approach may reduce the risk of endometrial and ovarian cancer, although ovarian deficiency symptoms also occur. For RRS, there are several issues that must be addressed to reduce the risk of cancer development in patients with HBOC or Lynch syndrome. To the best of our knowledge, this is the first review to discuss RRS with a focus on hereditary gynecological cancer.

Features of ovarian cancer in Lynch syndrome (Review)

Lynch syndrome is a hereditary ovarian cancer with a prevalence of 0.9-2.7%. Lynch syndrome accounts for 10-15% of hereditary ovarian cancers, while hereditary breast and ovarian cancer syndrome accounts for 65-75% of these cancers. The lifetime risk for ovarian cancer in families with Lynch syndrome is ~8%, which is lower than colorectal and endometrial cancers, and ovarian cancer is not listed in the Amsterdam Criteria II. More than half of sporadic ovarian cancers are diagnosed in stage III or IV, but ≥80% of ovarian cancers in Lynch syndrome are diagnosed in stage I or II. Ovarian cancers in Lynch syndrome mostly have non-serous histology and different properties from those of sporadic ovarian cancers. A screening method for ovarian cancers in Lynch syndrome has yet to be established and clinical studies of prophylactic administration of oral contraceptives are not available. However, molecular profiles at the genetic level indicate that ovarian cancer in Lynch syndrome has a more favorable prognosis than sporadic ovarian cancer. Inhibitors of the phosphatidylinositol 3-kinase/mammalian target of the rapamycin pathway and anti-epidermal growth factor antibodies may have efficacy for the disease. To the best of our knowledge, this is the first review focusing on ovarian cancer in Lynch syndrome.
