Abstract
Hereditary breast and ovarian cancer syndrome is an autosomal dominant cancer susceptibility syndrome mainly due to variants in BRCA1 or BRCA2 genes. Patients presenting with BRCA1 or BRCA2 gene mutations have a lifetime risk of developing breast or ovarian cancer (80% and 40%, respectively). Genetic testing to explore the predisposition to develop cancer represents a pivotal factor in such cases, and this review wants to explore the main implications in terms of medicolegal liability and insurance issues. Medicolegal issues related to these diagnostic processes include: (a) failure to recommend the test; (b) failure to properly interpret the test; (c) failure to correctly translate results into clinical practice; (d) lack of informed consent; and (e) failure to refer patients to specialized genetic counseling. Such errors may lead to compensation since the legal burden inherent in the efficacy of prophylactic interventions is a proof that requires the so-called 'preponderance of the evidence'. Concerning insurance issues, the carriers of such alleles without cancer are healthy because the genetic predisposition is not a disease per se but represents a (relevant) health risk. However, disclosure of these conditions can be impelled by insurers. It can lead to so-called 'genetic discrimination' because insurance companies might use genetic information to limit insurance options or increase their costs. Many private and public healthcare funders do not cover risk reducing surgeries, even when recommended as part of a risk reduction management plan for BRCA gene mutation carriers. Here, positions on these matters from different high income countries are discussed, stressing the importance of a common supranational or international regulatory framework to reach a trade-off between the economic interests of insurers and the rights of carriers not to disclose extremely sensitive information.

Abstract
OBJECTIVE To review the literature with reference to counselling and management of women with genetic predisposition to gynaecological cancers. METHODS Histochemical analysis, ultrasound, blood investigations, genetic testing, screening and risk-reducing surgery (RRS) are important tools for the management of gynaecological cancers and mortality reduction. Counselling can assist in timely management of gynaecological cancers. Systematic reviews, review articles, observational studies and clinical trials on PubMed, published in the English language, were included in this review. RESULTS The management of women with genetic predisposition to gynaecological cancers through screening tests and RRS has led to a significant decrease in the risk of malignancy through RRS in cases with BRCA1 and BRCA2 gene mutations. RRS and screening have also been found to reduce the mortality rate and increase the survival rate in women with BRCA1 and BRCA2 gene mutations. The efficacy of endometrial cancer surveillance in women with Lynch syndrome is still unproven. RRS has not been reported to be effective in women with Cowden syndrome. The risk of ovarian malignancies in individuals with germline mutations remains minimal in the general population in comparison with genetic mutations. CONCLUSION Genetic testing and RRS should be implemented in addition to genetic counselling for proper management and mortality reduction of women predisposed to gynaecological cancers.

Abstract
This study examines whether a change in the criteria for genetic testing for ovarian cancer risk changed the nature of referrals into our Familial Cancer service. This is a retrospective review of 273 women who underwent risk reducing surgery (RRS). The primary outcome was to establish whether there was an increase in women having RRS with a confirmed genetic mutation. Secondary outcomes included the incidence of occult cancer and of subsequent primary peritoneal cancer. The results showed an increase in women being offered RRS based on genetic diagnosis; 91% versus 32% before the criteria change. Four occult malignancies (1.5%) and two peritoneal cancers (0.7%) were noted.We have demonstrated a change in the nature of referrals to the familial cancer service from perceived risk to genetic diagnosis. We can now counsel women more accurately. With a defined risk we are enabling them to make an informed decision regarding risk reduction.

Abstract
Objective Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion of pelvic high-grade serous carcinoma (HGSC). Information on treatment and outcome of isolated STIC is rare. Therefore, we reviewed systematically the published literature to determine the incidence of subsequent HGSC in the high- and low-risk population and to summarize the current diagnostic and therapeutic options. Methods A systematic review of the literature was conducted in MEDLINE-Ovid, Cochrane Library and Web of Science of articles published from February 2006 to July 2021. Patients with an isolated STIC diagnosis and clinical follow-up were included. Study exclusion criteria for review were the presence of synchronous gynaecological cancer and/or concurrent non-gynaecological malignancies. Results 3031 abstracts were screened. 112 isolated STIC patients out of 21 publications were included in our analysis with a pooled median follow-up of 36 (interquartile range (IQR): 25.3-84) months. 71.4% of the patients had peritoneal washings (negative: 62.5%, positive: 8%, atypic cells: 0.9%). Surgical staging was performed in 28.6% of all STICs and did not show any malignancies. 14 out of 112 (12.5%) patients received adjuvant chemotherapy with Carboplatin and Paclitaxel. Eight (7.1%) patients developed a recurrence 42.5 (IQR: 33-72) months after isolated STIC diagnosis. Cumulative incidence of HGSC after five (ten) years was 10.5% (21.6%). Recurrence occurred only in BRCA1 carriers (seven out of eight patients, one patient with unknown BRCA status). Conclusion The rate of HGSC after an isolated STIC diagnosis was 7.1% with a cumulative incidence of 10.5% (21.6%) after five (ten) years. HGSC was only observed in BRCA1 carriers. The role of adjuvant therapy and routine surveillance remains unclear, however, intense surveillance up to ten years is necessary.

Abstract
Mesothelin (MSLN) is a protein expressed in the mesothelial cell lining of the pleura, peritoneum, and pericardium; its biological functions in normal cells are still unknown. Experimental studies using knockout mice have suggested that this molecule does not play an important role in development and reproduction. In contrast, it has been observed that this molecule is produced in abnormal amounts in several malignant neoplasms, such as mesotheliomas and pancreatic adenocarcinomas. Many molecular studies have also demonstrated that mesothelin is overexpressed in HSOCs. Here, we discuss the current knowledge of mesothelin and focus on its role in clinical and pathological diagnoses, as well as its impact on the prognosis of HSOC. Moreover, regarding the binding of MSLN to the ovarian cancer antigen CA125, which has been demonstrated in many studies, we also report on signal transduction pathways that may play an important role in the spread and neoplastic progression of this lethal neoplasm. Given that mesothelin is overexpressed in many solid tumours and has antigenic properties, this molecule could be considered an antigenic target for the treatment of many malignancies. Consequently, we also review the literature to report on mesothelin-targeting therapies for HSOC that have been recently investigated in many clinical studies.

Abstract
Pathogenic germline variants underlie up to 20% of ovarian cancer (OC) and are associated with varying degrees of risk for OC. For mutations in high-penetrance genes such as BRCA1/2, the role of risk-reducing bilateral salpingo-oophorectomy (RRSO) in cancer prevention is well-established and improves mortality. However, in moderate-penetrance genes where the degree of risk for OC is less precisely defined, the role of RRSO is more controversial. Although national guidelines have evolved to incorporate gene-specific recommendations, studies demonstrate significant variations in practice. Given this, our multidisciplinary group has reviewed the available literature on risk estimates for genes associated with OC, incorporated levels of evidence, and set thresholds for consideration of RRSO. We found that the benefit of RRSO is well-established for pathogenic variants in BRCA1/2 as well as BRIP1 and RAD51C/D where the risk of OC is elevated beyond our threshold for RRSO. In PALB2, RRSO is particularly controversial as newer studies consistently demonstrate an increased risk of OC that is dependent on family history, making uniform recommendations challenging. Additionally, new guidelines for Lynch syndrome provide gene-specific risks, questioning the role of RRSO, and even hysterectomy, for MSH6 and PMS2 mutation carriers. Given these uncertainties, shared decision making should be used around RRSO with discussion of individual risk factors, family history, and adverse effects of surgery and premature menopause. Herein, we provide a clinical guide and counseling points.

Abstract
Gynecologic cancers are more often caused by genetic factors than other cancers. Genetic testing has become a promising avenue for the prevention, prognosis, and treatment of cancers. This review describes molecular features of gynecologic tumors linked to hereditary syndromes, gives an overview of the current state of clinical management, and clarifies the role of gynecology in the treatment of hereditary tumors. Typical hereditary gynecologic tumors include hereditary breast and ovarian cancer, Lynch syndrome, Peutz-Jeghers syndrome, and Cowden syndrome. Multigene panel testing, which analyzes a preselected subset of genes for genetic variants, has recently become the first-choice test because it can provide more accurate risk assessment than a single test. Furthermore, comprehensive genomic cancer profiling enables personalized cancer treatment and aids in germline findings.

Abstract
OBJECTIVE Serous tubal intraepithelial carcinoma (STIC) is currently considered the precursor lesion of pelvic high-grade serous carcinoma. The management of STIC diagnosed after risk-reducing salpingo-oophorectomy (RRSO) in women with BRCA1-2 variants remains unclear. The aim of our study was to evaluate the incidence of STIC, serous tubal intraepithelial lesions (STIL) and occult invasive cancer (OC) and to determine the long-term outcomes of these patients. METHODS We conducted a retrospective study of patients with BRCA 1-2 variants who underwent RRSO between January-2010 and Dicember-2020 at the Clinic of Gynaecology of University of Padova. INCLUSION CRITERIA women with a negative pelvic examination at the last screening prior to RRSO, patients with fallopian tubes analysed using the SEE-FIM protocol. EXCLUSION CRITERIA patients with a positive gynaecologic screening or with ovarian/tubal cancer prior to RRSO. RESULTS We included 153 patients. STICs were diagnosed in 4 patients (2.6%) and STILs in 6 patients (3.9%). None of the patients with STIC underwent restaging surgery or adjuvant chemotherapy; all patients were followed closely every 6 months. None of the patients developed primary peritoneal carcinomas (PPCs) with a median FUP of 54.5 months (15-106). OC was diagnosed in 3 patients (2%). All patients with OC underwent staging surgery, and one patient developed a peritoneal carcinoma (PC) after 18 months by staging surgery. CONCLUSION(S) The incidence of STIC, STIL and OC after RRSO in BRCA1-2 variants was low. Our results demonstrated that long-term close surveillance in patients diagnosed with STIC should be considered a possible management strategy.

Abstract
Pathologic involvement of the peritoneum can result from a wide variety of conditions, including both neoplastic and non-neoplastic entities. Neoplastic involvement of the peritoneal ligaments, mesenteries, and spaces from malignant spread of epithelial cancers, termed peritoneal carcinomatosis, is frequently encountered at CT evaluation. However, a host of other more unusual benign and malignant neoplasms can manifest with peritoneal disease, including both primary and secondary peritoneal processes, many of which can closely mimic peritoneal carcinomatosis at CT. In this review, we discuss a wide array of unusual peritoneal-based neoplasms that can resemble the more common peritoneal carcinomatosis. Beyond reviewing the salient features for each of these entities, particular emphasis is placed on any specific clinical and CT imaging clues that may allow the interpreting radiologist to appropriately narrow the differential diagnosis and, in some cases, make an imaging-specific diagnosis.

Abstract
Risk‐reducing bilateral salpingo‐oophorectomy (RRBSO) is highly effective for the prevention of high‐grade serous ovarian cancer (HGSOC) in BRCA1/2 pathogenic variant carriers (PVCs), but does not completely eliminate future risk of primary peritoneal cancer (PPC). The requirement to completely remove fallopian tubes at RRBSO and carefully exclude occult cancer/serous tubal intraepithelial carcinoma (STIC) lesions may not have been appreciated historically. We calculated rates of HGSOC and PPC in confirmed BRCA1/2 PVCs registered on the regional database in those who did (cases) and did not (controls) undergo RRBSO after genetic testing. Expected annual rates of ovarian/peritoneal cancer were 1% for BRCA1 ≥ 35 years and 0.5% for BRCA2 ≥ 45 years. Follow‐up before 35/45 years was “risk free” and lead time excluded RRBSO <35 years and <45 years for BRCA1 and BRCA2, respectively. Women were followed from personal mutation report (controls) or RRBSO (cases) to death, ovarian/peritoneal cancer or last follow‐up, whichever was sooner. In total, 891 cases (BRCA1 = 468, BRCA2 = 423) and 1302 controls had follow‐up ≥35 years (BRCA1 = 736) and ≥45 years (BRCA2 = 566), respectively, over a total of 7261.1 risk eligible years (mean = 8.15 years). Twenty‐one occult ovarian cancers were found at RRBSO (2.4%), 16 at stage 1. Post RRBSO, 56.97 ovarian/peritoneal cancers were expected but only 3 were observed (HR = 0.053; 95% CI = 0.013‐0.14), with combined Kaplan‐Meier analysis HR = 0.029 (95% CI = 0.009‐0.100, P < .001). Risk reduction was greater in specialist (HR = 0.03; 95% CI = 0.001‐0.13) compared to non‐specialist centres (HR = 0.11; 95% CI = 0.02‐0.37) (P = .07). In controls, 23.35 ovarian/peritoneal cancers were expected with 32 observed (HR = 1.37; 95% CI = 0.95‐1.91). RRBSO <35/<45 years reduces the risk of ovarian/peritoneal cancer by 95% in BRCA1/2 PVCs and may be greater in specialist centres. What's new? Women who carry genetic variants in BRCA1/2 that are linked to high‐grade serous ovarian cancer are advised to undergo risk‐reducing prophylactic bilateral salpingo‐oophorectomy (RRBSO). RRBSO, however, is associated with a significant residual risk of primary peritoneal cancer (PPC). Here, the rate of PPC following prophylactic surgery for high‐grade serous ovarian cancer was investigated among 2,193 BRCA1/2 mutation carriers who had undergone RRBSO. Estimates indicate that prophylactic surgery reduced the overall risk of PPC by 95 percent, a far greater reduction than previously described. Residual risk was lowest when RRBSO was carried out at specialist centers compared to non‐specialist centers.

Abstract
The discovery of genes underlying inherited predisposition to breast and ovarian cancer has revolutionized the ability to identify women at high risk for these diseases before they become affected. Women who are carriers of deleterious variants in these genes can undertake surveillance and prevention measures that have been shown to reduce morbidity and mortality. However, under current strategies, the vast majority of women carriers remain undetected until they become affected. In this review, we show that universal testing, particularly of the BRCA1 and BRCA2 genes, fulfills classical disease screening criteria. This is especially true for BRCA1 and BRCA2 in Ashkenazi Jews but is translatable to all populations and may include additional genes. Utilizing genetic information for large-scale precision prevention requires a paradigmatic shift in health-care delivery. To address this need, we propose a direct-to-patient model, which is increasingly pertinent for fulfilling the promise of utilizing personal genomic information for disease prevention.

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

Abstract
High-grade serous ovarian cancer (HGSOC) is the most common and deadly subtype of ovarian cancer as it is commonly diagnosed after substantial metastasis has already occurred. The past two decades have been an active era in HGSOC research, with new information on the origin and genomic signature of the tumor cell. Additionally, studies have begun to characterize changes in the HGSOC microenvironment and examine the impact of these changes on tumor progression and response to therapies. While this knowledge may provide valuable insight into better prognosis and treatments for HGSOCs, its collection, synthesis, and application are complicated by the number of unique microenvironments in the disease-the initiating site (fallopian tube), first metastasis (ovary), distal metastases (peritoneum), and recurrent/platinum-resistant setting. Here, we review the state of our understanding of these diverse sites and highlight remaining questions.

Abstract
Women with BRCA variants have a high lifetime risk of developing breast and ovarian cancer. The aim of this study was to investigate the standard incidence ratios (SIR) for breast and ovarian cancer and standard mortality ratios (SMR) in a population-based cohort of women in Western Sweden, under surveillance and after risk reducing surgery. Women who tested positive for a BRCA variant between 1995–2016 (n = 489) were prospectively registered and followed up for cancer incidence, risk reducing surgery and mortality. The Swedish Cancer Register was used to compare breast and ovarian cancer incidence and mortality with and without risk reducing surgery for women with BRCA variants in comparison to women in the general population. SIR for breast cancer under surveillance until risk-reducing mastectomy (RRM) was 14.0 (95% CI 9.42–20.7) and decreased to 1.93 (95% CI 0.48–7.7) after RRM. The SIR for ovarian cancer was 124.6 (95% CI 59.4–261.3) under surveillance until risk reducing salpingo-oophorectomy (RRSO) and decreased to 13.5 (95% CI 4.34–41.8) after RRSO. The SMR under surveillance before any risk reducing surgery was 5.56 (95% 2.09–14.8) and after both RRM and RRSO 4.32 (95% CI 1.62–11.5). Women with cancer diagnoses from the pathology report after risk reducing surgery were excluded from the analyses. Risk reducing surgery reduced the incidence of breast and ovarian cancer in women with BRCA variants. However, overall mortality was significantly increased in comparison to the women in the general population and remained elevated even after risk reducing surgery. These findings warrant further research regarding additional measures for these women.

Abstract
High-grade serous (HGSC) stands apart from the other ovarian cancer histotypes in being the most frequent, in occurring as part of a genetic predisposition in a significant proportion of cases, and in having the poorest clinical outcomes. Although the pathologic diagnosis of HGSC is now made with high accuracy, there remain areas of disagreement regarding viewpoints on tissue site of origin and designation of primary site, with impact on staging in low-stage cases, as well as difficulties in reproducible and clinically relevant reporting of HGSC in specimens taken after neoadjuvant chemotherapy. These areas are discussed in the current article.

Abstract
BACKGROUND Primary peritoneal cancer (PPC) patients with BRCA mutations have a good prognosis; however, for patients with BRCA mutations who are diagnosed with PPC after prophylactic salpingo-oophorectomy (PSO), the prognosis is poor, and survival information is scarce.
CASE SUMMARY We treated a 56-year-old woman with PPC after bilateral mastectomy, hysterectomy, and bilateral salpingo-oophorectomy. This patient had primary drug resistance and died 12 mo after the diagnosis of PPC. The genetic test performed on this patient indicated the presence of a germline BRCA1 mutation. We searched the PubMed, Scopus, and Cochrane databases and extracted studies of patients with BRCA mutations who developed PPC after PSO. After a detailed literature search, we found 30 cases, 7 of which had a history of breast cancer, 14 of which had no history of breast cancer, and 9 of which had an unknown history. The average age of PSO patients was 48.86 years old (range, 31-64 years). The average time interval between the diagnosis of PPC and preventive surgery was 61.03 mo (range, 12-292 mo). The 2-year survival rate for this patient population was 78.26% (18/23), the 3-year survival rate was 50.00% (9/18), and the 5-year survival rate was 6.25% (1/16).
CONCLUSION Patients with BRCA mutations who are diagnosed with PPC after preventative surgery have a poor prognosis. Prevention measures and treatments for these patients need more attention.

Abstract
Bilateral salpingo-oophorectomy (BSO) is increasingly employed as a risk-reducing strategy for epithelial ovarian cancer (EOC). We report the third case of a patient developing primary peritoneal cancer two decades after a bilateral salpingo-oophorectomy. This 66-year-old female underwent a hysterectomy for pelvic pain at age 28 and a subsequent bilateral salpingo-oophorectomy (BSO) at age of 45 for a pelvic mass. Presenting with a 6-month history of increasing abdominal girth, decreased energy, and a reduction in appetite, she was consented for a unilateral salpingo-oophorectomy, omentectomy, and cytoreductive surgery. Pathology specimens revealed a high grade metastatic papillary serous carcinoma consistent with a primary gynecologic origin. It is unlikely that an occult malignancy was missed at the time of pathologic assessment following her previous BSO; therefore it provides evidence that primary peritoneal cancers can arise through the malignant transformation of benign endosalpingiosis.

Abstract
BACKGROUND Risk-reducing salpingo-oophorectomy (RRSO) is recommended for BRCA1/2 mutation carriers because of their increased risk of ovarian carcinoma. Despite RRSO, metachronous peritoneal carcinomatosis occasionally is diagnosed. METHODS The literature was searched for BRCA1/2 mutation carriers with peritoneal carcinomatosis after risk-reducing surgery. The authors were asked for additional data. Clinical and histopathological data were descriptively analyzed. Cases were compared with a single-institution control cohort. RESULTS Of 36 cases, 86.1% concerned BRCA1 mutation carriers. The median age of the patients was 52 years (range, 30-71 years) at the time of risk-reducing surgery and 60 years (range, 37-75 years) at the time of diagnosis of peritoneal carcinomatosis. The median interval between the 2 events was 54.5 months (range, 11-292 months). Peritoneal carcinomatosis was mostly high-grade serous carcinoma. Histopathological details of the RRSO specimens were retrieved in 8 cases; 5 (62.5%) were found to have serous tubal intraepithelial carcinoma and 1 had epithelial atypia. Cases were older (P = .025) at the time of risk-reducing surgery and harbored more serous tubal intraepithelial carcinomas (P<.001) compared with women from the control cohort. CONCLUSIONS Metachronous peritoneal carcinomatosis after risk-reducing surgery occurs predominantly in BRCA1 mutation carriers, usually within 5 years. Data have suggested that surgery at a younger age lowers the rates of peritoneal carcinomatosis. These data can be used in the gynecologic counseling of BRCA1/2 mutation carriers. RRSO should include complete salpingectomy. Detailed histopathological examination of specimens removed during RRSO is essential. Cancer 2018;124:952-9. © 2018 American Cancer Society.

Abstract
Primary peritoneal carcinoma is usually advanced at diagnosis and curability is low unless the patient has a small tumor burden. Peritoneal carcinoma can occur in association with hereditary breast and ovarian cancer syndrome, which is thought to account for 5-6% of all breast cancer. Mutations of two breast cancer susceptibility genes, BRCA1 and BRCA2, are responsible for hereditary breast and ovarian cancer. Women with BRCA1/2 mutations often undergo risk-reducing salpingo-oophorectomy (RRSO) to prevent both ovarian and breast cancer. However, peritoneal carcinoma has been reported to develop after RRSO in patients with BRCA1/2 mutations. We experienced a patient with peritoneal carcinoma and inguinal lymph node metastasis after surgical resection of breast cancer and subsequent RRSO. This report describes the first case of peritoneal carcinoma arising after RRSO in a Japanese patient with BRCA1 mutation, including a review of the literature on peritoneal carcinoma associated with BRCA1/2 mutation.

Abstract
Hereditary breast and ovarian cancer syndrome is an inherited cancer-susceptibility syndrome characterized by multiple family members with breast cancer, ovarian cancer, or both. Based on the contemporary understanding of the origins and management of ovarian cancer and for simplicity in this document, ovarian cancer also refers to fallopian tube cancer and primary peritoneal cancer. Clinical genetic testing for gene mutations allows more precise identification of those women who are at an increased risk of inherited breast cancer and ovarian cancer. For these individuals, screening and prevention strategies can be instituted to reduce their risks. Obstetrician-gynecologists play an important role in the identification and management of women with hereditary breast and ovarian cancer syndrome. If an obstetrician-gynecologist or other gynecologic care provider does not have the necessary knowledge or expertise in cancer genetics to counsel a patient appropriately, referral to a genetic counselor, gynecologic or medical oncologist, or other genetics specialist should be considered (1). More genes are being discovered that impart varying risks of breast cancer, ovarian cancer, and other types of cancer, and new technologies are being developed for genetic testing. This Practice Bulletin focuses on the primary genetic mutations associated with hereditary breast and ovarian cancer syndrome, BRCA1 and BRCA2, but also will briefly discuss some of the other genes that have been implicated.

Abstract
Background Although breast cancer is relatively common, only about 5% of cases are due to inheritance of highly penetrant cancer susceptibility genes. The majority of these are caused by mutations in the BRCA1 and BRCA2 genes, which are also associated with an increased risk of ovarian cancer. Increased surveillance, chemoprevention, and prophylactic surgeries are standard options for the effective medical management of mutation carriers. However, optimal management of female carriers who choose to undergo prophylactic surgeries is still poorly understood. Methods The authors provide an overview of the current literature regarding medical management options for women carriers of BRCA1 and BRCA2 gene mutations and the implications for those individuals who have chosen to undergo prophylactic surgeries. Results BRCA mutation carriers who opt for prophylactic surgeries are still at risk for development of malignancy, and appropriate monitoring is warranted. Conclusions There are limited data on the appropriate medical management for BRCA mutation carriers after prophylactic surgeries. However, a management plan can be extrapolated from the general management recommendations for surveillance and other risk-reducing strategies in BRCA-positive individuals.

Abstract
More than 40 years ago Lynch et al. described several multigenerational breast cancer family pedigrees which demonstrated autosomal dominant inheritance of a trait(s) that increased risks for both breast and ovarian cancers. Mutation carriers in at least 90 % of these hereditary breast ovarian cancer (HBOC) syndrome families have been linked to cancer-associated mutations in the genes BRCA1 and BRCA2. This review focuses on the contributions of Lynch, colleagues and collaborators and pertinent literature, toward defining the HBOC syndrome, the cancer risks that the inherited adverse mutations convey, the gynecologic tissues and organs from which the malignancy may arise to disseminate throughout the pelvic and abdominal organs and peritoneum and how this information can be used to reduce the risk and morbidities of intra-abdominal carcinomatosis in effected individuals.

Abstract
Harmful mutations of the BRCA tumor suppressor genes result in a greater lifetime risk for malignancy-breast and ovarian cancers in particular. An increased risk for male breast, fallopian tube, primary peritoneal, pancreatic, prostate, and colon cancers also has been reported. The BRCA gene is inherited in an autosomal dominant pattern and tends to be highly penetrant; thus, there is an increased incidence of these cancers in affected families. Compared with sporadic tumors, BRCA-associated malignancies have unique manifestations, clinical features, and pathologic profiles. Manifestation at an early patient age, high-grade tumors, and an aggressive clinical course are common features of BRCA-associated malignancies. Understanding the behavior of these cancers aids in identification of affected individuals and families, who can then make informed decisions regarding their future health. Enhanced screening, prophylactic surgery, and chemoprevention are options for managing cancer risk factors in these individuals. Imaging has an important role in the screening, evaluation, staging, and follow-up of BRCA-associated malignancies. Supplemental screening of BRCA mutation carriers often begins at an early age and is critical for early and accurate cancer diagnoses. The authors review the etiopathogenesis and imaging features of BRCA-associated malignancies, the importance of a multidisciplinary approach to determining the diagnosis, and the treatment of patients who have these mutations to improve their outcomes. © RSNA, 2017.

Early-onset primary peritoneal carcinoma from atypical cells after risk-reducing salpingo-oophorectomy for BRCA2 mutation carrier: a case report. Int Cancer Conf J 2017; 6:104-108. [PMID: 31149481 DOI: 10.1007/s13691-017-0287-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2016] [Accepted: 03/08/2017] [Indexed: 10/19/2022] Open
Abstract
Risk-reducing salpingo-oophorectomy (RRSO) in BRCA mutation carriers is performed to reduce carcinogenesis. It decreases the ovarian, tubal, and peritoneal cancer risk to 3.5-4.3% and breast cancer risk to 30-40%. According to a previous study, despite RRSO, 3.4% of patients develop breast cancer and 0.8% develop peritoneal cancer. However, the long-term risk of recurrence and appropriate treatment for patients with unsuspected neoplasia after RRSO are unclear. Case: A 61-year-old woman who had a BRCA2 mutation underwent RRSO. Her pelvic washing cytology showed atypical cells, and similar atypical cells were identified on her fimbria. She underwent strict surveillance. Elevated CA125 levels and increased ascites in the pelvic cavity were detected by routine surveillance at 18 months after RRSO. She underwent staging laparotomy and was diagnosed with primary peritoneal carcinoma stage IIIC. It is helpful to perform surveillance by transvaginal ultrasound and serum CA125 analyses in cases that require strict management. The appropriate intervention should be considered for cases in which atypical cells or non-invasive carcinoma are detected after RRSO.

Abstract
STUDY OBJECTIVE To assess the potential role of peritoneal and omental biopsies in women undergoing risk-reducing salpingo-oopherectomy (RRSO) for prophylactic management of hereditary breast/ovarian cancer (HBOC) syndromes. DESIGN A retrospective observational cohort (Canadian Task Force classification II.1). SETTING An academic gynecology practice. PATIENTS All women who underwent RRSO for a high-risk BRCA1/2 mutation or deletion at a single institution between January 2003 and June 2016. INTERVENTIONS After obtaining institutional review board approval, patient demographics, types of surgical intervention, histopathology reports, and outcomes were abstracted. Bilateral fallopian tubes were histologically evaluated using the "sectioning and extensively examining of the fimbriated end" protocol. Descriptive statistics were used to summarize findings. MEASUREMENTS AND MAIN RESULTS Seventy women underwent RRSO within the study window; 60% (n = 42) carried a high-risk mutation in BRCA1, 37.1% (n = 26) carried a high-risk mutation in BRCA2, and 2.9% (n = 2) had a high-risk BRCA deletion identified by BRAC analysis rearrangement testing (BART). Serous tubal intraepithelial carcinomas were identified in the distal fallopian tube of 3 subjects. In addition to RRSO, subjects underwent pelvic washings (n = 58, 82.9%), omental biopsy (n = 44, 62.9%), peritoneal biopsies of the bilateral paracolic gutters (n = 51, 72.9%), anterior and posterior cul-de-sac (n = 53, 75.7%), and rectosigmoid mesentery (n = 11, 15.7%). Rare atypical cells favoring reactive cells were identified in pelvic washings of 1 subject (1.7%) with histologically normal fallopian tubes. No evidence of atypical mesothelial proliferations or carcinoma was identified in any omental or peritoneal biopsies. The mean duration of follow-up was 32.5 ± 24.7 months. At the last contact, 3 women (4.3%) had died of metastatic breast cancer, whereas another 3 (4.3%) had been diagnosed with a recurrence of their breast cancer. All other subjects were alive and well (n = 64, 91.4%). CONCLUSION The routine use of peritoneal and omental biopsies for women undergoing RRSO does not appear to improve detection of occult malignancy.

Abstract
Salient to the intent of personalized medicine, hereditary cancer syndromes present significant opportunities in the treatment and prevention of some gynecologic cancers. Mutations in BRCA1, BRCA2, and DNA mismatch repair genes: MLH1, MSH2, MSH6, and PMS2 are important causal agents in hereditary breast and ovarian cancer (HBOC) and Lynch syndromes. Though they only account for an estimated 10-18% of ovarian, tubal, peritoneal, and endometrial cancer cases, inherited cancers are imminently preventable if mutation carriers are identified in a timely manner. Population level screening is currently impractical due to low prevalence of disease, cost of testing, and ethical issues associated with testing, so diagnosis of these mutations is limited. Being affected by one of the heritable gynecologic malignancies is a logical entry point into the genetic counseling and testing pipeline for the patient and her family members. Thus, gynecologic cancer providers are uniquely positioned to diagnose germline mutations that can inform prognosis and treatment for their patients in addition to enabling prevention for patients' cancer-unaffected blood relatives, or "previvors". The purpose of this review is to describe our current perspective on testing for and implications of heritable cancer syndromes in the women with ovarian, tubal, peritoneal, and endometrial cancers.

Abstract
Background There are no effective methods of diagnosis of early-stage ovarian cancer. Conservative care over patients at high risk of ovarian and breast cancers is ineffective. Prophylactic surgery is considered the best prophylaxis among BRCA1/BRCA2 carriers. Methods One hundred ninety-five patients, carriers of one of three most common mutations of the BRCA1 gene (Am J Hum Genet: 66: (6)1963-1968, 2000) in the Polish population (5382insC, 4153delA and C61G), who undergone prophylactic salpingo-oophorectomy. The study group consisted of consecutive mutation carriers living in Poland, in the West Pomeranian province. Histopathological examination of the surgical material failed to reveal presence of malignancy. Results During follow-up we diagnosed two peritoneal cancers and 14 breast cancers. Diagnosis of breast cancer before prophylactic surgery increased the risk of peritoneal cancer almost three times. Time from diagnosis of breast cancer to prophylactic surgery increased the risk of peritoneal cancer after prophylactic surgery. This was strongly expressed (HR = 5.0; p = 0.030) in cases of over five-year-long delay in prophylactic surgery. Diagnosis of breast cancer before prophylactic surgery correlated with the risk of death (p = 0.00010). Presence of 5382insC mutation decreased and C61G mutation increased the risk of peritoneal cancer (p = 0.049 vs. p = 0.013). Conclusions Occurrence of primary peritoneal cancer after prophylactic surgery is similar to that reported in international literature. Primary breast cancer occurred less often than in international literature. We suspect that the risk of development of breast cancer among BRCA1 carriers undergoing prophylactic surgery can differ in a population. The next goal should be to study the molecular basis for the risk of development of malignancies in any population. Carriers of BRCA1 gene diagnosed with breast cancer should undergo prophylactic surgery within five years from the diagnosis of breast cancer.

Abstract
As the testing criteria for BRCA expand, we are identifying a greater number of young women at significant risk for breast and ovarian cancer. Fortunately, there is strong evidence to support risk reduction from mastectomy and oophorectomy. However, these surgeries come with significant psychological and physical health consequences. For breast cancer, screening with mammogram and magnetic resonance imaging may be a reasonable approach for a woman who does not desire surgery. However, there is no evidence to suggest any efficacy in screening for ovarian cancer, and women electing to not undergo surgery must have a detailed discussion with their physician regarding the risks and benefits of different management strategies. As more women are electing to undergo surgical risk reduction, providers must also be able to counsel and care for these women who will face unique health challenges after surgical menopause at a young age. A review of the current evidence behind management of the BRCA woman follows, with a focus on areas of controversy and current research.

Abstract
Ovarian cancer (OC) mostly arises sporadically, but a fraction of cases are associated with mutations in BRCA1 and BRCA2 genes. The presence of a BRCA mutation in OC patients has been suggested as a prognostic and predictive factor. In addition, the identification of asymptomatic carriers of such mutations offers an unprecedented opportunity for OC prevention.
This review is aimed at exploring the current knowledge on epidemiological and molecular aspects of BRCA-associated OC predisposition, on pathology and clinical behavior of OC occurring in BRCA mutation carriers, and on the available options for managing asymptomatic carriers.

Abstract
An autosomal-dominant inherited trait predisposing women to both breast cancer (BC) and ovarian cancer (OC) was first described in 1971. Subsequent strides were made in identifying mutations in the eventually cloned genes BRCA1 and BRCA2 as being responsible for hereditary BC and OC (HBOC) in many women with early-onset HBOC. More recently, modifiers of BC risk have also been identified and are under study. The biological and molecular genetic pathways for malignant transformation in OC (ovarian epithelium and/or epithelium of the fallopian tube or, possibly, the endometrium and endocervix) remain elusive. The answer to the question 'What have we learned?' which is part of our chapter title unfortunately remains incomplete. However, intensive worldwide research indicates that its malignant transformation is the product of a multi-step process where there is an array of mutations which account for three or more classes of genes, inclusive of proto-oncogenes, tumor suppressor genes and mutator genes. This causal uncertainty heralds an enormous clinical-pathology dilemma, given the fact that epithelial OC, together with related Müllerian duct carcinoma, harbor the highest fatality rates of all gynecologic malignancies.

Abstract
Women who inherit a mutation in either the BRCA1 or BRCA2 gene have greatly elevated lifetime risks of ovarian cancer, fallopian tube cancer and breast cancer. Preventive surgical removal of the ovaries and fallopian tubes (salpingo-oophorectomy) is recommended to these women, often prior to natural menopause, to prevent cancer. The ensuing hormone deprivation may impact on health and quality of life. Most of these women experience menopausal symptoms shortly after surgery; however, there may also be longer term consequences that are less well understood. In this review, we highlight recent studies that examine the implications of salpingo-oophorectomy on health and quality of life in BRCA-positive women and we discuss the care of women following prophylactic surgery.

Abstract
Although most gynecologic malignancies are sporadic, hereditary cancer syndromes cause a substantial portion of these cancers. Given that the diagnosis of these syndromes has prognostic and therapeutic implications for the patient, as well as preventive implications for her family members, genetic testing is now an accepted part of the management of the patient who has gynecologic cancer.

Abstract
BACKGROUND Patients with ovarian cancer usually present to a family physician with nonspecific symptoms, most often abdominal pain. The outcome depends above all on the stage of the disease when it is diagnosed and on the quality of treatment. METHODS This article is based on a review of selected publications from 2000 to 2010 that were retrieved by an automated search in Medline on the terms "ovarian cancer," "screening," "diagnosis," "treatment," and "prognosis," as well as the interdisciplinary S2k guideline Diagnostik und Therapie maligner Ovarialtumoren (the diagnosis and treatment of malignant ovarian tumors) issued in 2007 by the Ovarian Tumor Committee of the German Consortium of Gynecologic Oncology (AGO) and the Committee's updated recommendations of 2009. RESULTS The proper treatment of early ovarian cancer involves resection of the primary tumor and all macroscopically visible tumor mass as well as meticulous inspection of the entire abdominal cavity for staging. Platinum-based chemotherapy is indicated for women with ovarian cancer in FIGO stage I to IIA (except stage IA, G1). For women with advanced ovarian cancer, the prognosis largely depends on the extent of tumor mass reduction on initial surgery. Complete resection confers significantly longer survival (median 5 years) than incomplete resection. After surgery, the standard adjuvant chemotherapy consists of a combination of carboplatin and paclitaxel. Treatment that conforms to published guidelines significantly improves survival (60% versus 25% at 3 years). CONCLUSION The possibility of ovarian cancer must be considered for any woman who presents with new, persistent, nonspecific abdominal pain. Ovarian cancer should always be treated in accordance with published guidelines.

Abstract
Hereditary breast and ovarian cancer due to mutations in the BRCA1 and BRCA2 genes is the most common cause of hereditary forms of both breast and ovarian cancer. The overall prevalence of BRCA1/2 mutations is estimated to be from 1 in 400 to 1 in 800 with a higher prevalence in the Ashkenazi Jewish population (1 in 40). Estimates of penetrance (cancer risk) vary considerably depending on the context in which they were derived and have been shown to vary within families with the same BRCA1/2 mutation. This suggests there is no exact risk estimate that can be applied to all individuals with a BRCA1/2 mutation. The likelihood of harboring a BRCA1 or BRCA2 mutation is dependent on one's personal and/or family history of cancer and can be estimated using various mutation probability models. For those individuals who have a BRCA1 or BRCA2 mutation, several screening and primary prevention options have been suggested, including prophylactic surgery and chemoprevention. Once a BRCA1 or BRCA2 mutation has been identified in a family, testing of at-risk relatives can identify those family members who also have the familial mutation and thus need increased surveillance and early intervention when a cancer is diagnosed.

Abstract
Risk-reducing salpingo-oophorectomy (RRSO) is widely used for cancer risk reduction in BRCA1 or BRCA2 (BRCA1/2) mutation carriers. Occult ovarian/fallopian tube cancers (OOC) detected at the time of RRSO have been reported in several studies with wide variability in reported prevalence. We estimated the prevalence of OOC in a prospective cohort of 647 BRCA1/2 mutation carriers from 18 centers (PROSE consortium) who underwent RRSO between 2001 and 2008. OOC was detected in 16 of 647 women (2.5%). The mean age at RRSO was 51.7 in those with OOC versus 46.6 in those without OOC (P = 0.017). Twelve of the 16 OOCs (75%) were diagnosed in women with BRCA1 mutations. Thirty-eight percent of women with OOC had stage 1 cancer versus none of the women in the PROSE database diagnosed with ovarian cancer outside of screening. Among 385 women (60%) in whom pathology reports were available for central review, 246 (64%) RRSOs were performed at participating PROSE centers while 139 (36%) were performed at local sites. Ovarian and fallopian tube tissues removed at major genetics referral centers were significantly more likely to have been examined in toto compared to specimens obtained at non-referral centers (75% vs. 30%, P < 0.001). Our results confirm that OOC may be found at the time of RRSO in BRCA1/2 mutation carriers and suggest that OOC are of a more favorable stage than cancers found outside RRSO. An unacceptably high proportion of pathologic examinations did not adequately examine ovaries and fallopian tubes obtained at RRSO.

Abstract
PURPOSE OF REVIEW Hereditary non-polyposis colorectal cancer (HNPCC) or Lynch syndrome is characterized by a number of other cancers including colorectal, endometrial and ovarian cancer. This review covers the gynaecological aspects of managing women with HNPCC: diagnostic criteria, molecular tests for diagnosis, cancer risks and different strategies for surveillance and prevention. RECENT FINDINGS Studies correcting for ascertainment bias found slightly lower penetrance estimates than those obtained from high-risk families. HNPCC linked ovarian cancer presents at an earlier age and stage and has similar survival rates as sporadic cancer. In endometrial tumours, microsatellite instability or immunohistochemistry has limited effectiveness in selecting individuals for genetic testing, due to molecular differences. Population-based data indicate that a significant proportion of mismatch repair gene carriers would be missed by current clinical criteria. Effective risk prediction models complement clinical risk assessment. Effectiveness of screening is unproven and prophylactic surgery is the best preventive option for women who have completed their families. Multimodal screening protocols from the age of 30-35 years are being evaluated. SUMMARY Risk of endometrial cancer in women with Lynch syndrome is as high as the risk of colorectal cancer. Further research is needed to identify the appropriate strategy for clinical risk assessment and optimize screening. A multidisciplinary approach is necessary to manage these women.

Abstract
Hereditary ovarian cancer accounts for at least 5% of the estimated 22,000 new cases of this disease during 2009. During this same time, over 15,000 will die from malignancy ascribed to ovarian origin. The bulk of these hereditary cases fits the hereditary breast-ovarian cancer syndrome, while virtually all of the remainder will be consonant with the Lynch syndrome, disorders which are autosomal dominantly inherited. Advances in molecular genetics have led to the identification of BRCA1 and BRCA2 gene mutations which predispose to the hereditary breast-ovarian cancer syndrome, and mutations in mismatch repair genes, the most common of which are MSH2 and MLH1, which predispose to Lynch syndrome. These discoveries enable relatively certain diagnosis, limited only by their variable penetrance, so that identification of mutation carriers through a comprehensive cancer family history might be possible. This paper reviews the subject of hereditary ovarian cancer, with particular attention to its molecular genetic basis, its pathology, and its phenotypic/genotypic heterogeneity.

Abstract
PURPOSE The aim of this article was to determine the accuracy and efficiency of World Wide Web ("Web") resources to help nongeneticists answer four clinical questions about each of five common genetic conditions. METHODS Correct answers were established by literature review. Two open-access genetics resources and seven general subscription resources were reviewed. Scoring criteria were established to define complete, partial, vague, inconsistent, not found, and wrong answers. The main outcome measures were number of answers found, accuracy, and completeness of answers. Efficiency (time per answer found) was a secondary measure. RESULTS Overall, the databases contained complete answers 33.3% of the time but contained no information as frequently (33.9%). The best database had complete answers 70% of the time, whereas the worst contained no complete answers. Five of the seven subscription databases had a total of eight wrong answers. The other two subscription databases and the two open-access genetics databases had no wrong answers. Search time ranged from 3.2 to 18.3 minutes per complete answer. CONCLUSIONS Nongeneticist providers do not have a Web resource that is accessible, accurate, and efficient to answer genetic questions that might arise in practice.

Abstract
BACKGROUND Prophylactic salpingo-oophorectomy (SO), which is recommended in BRCA1/2 mutation carriers, still needs to be reappraised. METHODS In all, 89 BRCA1/BRCA2 mutation carriers underwent SO between 1994-2004. Past medical and familial history, SO, results and survival after SO were analyzed. RESULTS The series consisted of 56 BRCA1 and 33 BRCA2 mutation carriers. All but 1 had a family history of breast (BC) and/or ovarian cancer; 42 BRCA1 and 31 BRCA2 had a personal history of BC. The median age at SO was 44 (BRCA1) and 49.5 (BRCA2) years for women without previous BC (not significant) and 48 (BRCA1) and 53 BRCA2) years (P=.03) for women with previous BC. Occult ovarian (n=2) and/or fallopian (n=3) carcinomas were found in 4 patients (4.5%): 1 experienced recurrence (4 years), 2 are disease-free (26 and 38 months of follow-up), and 1 died from BC (12 months). Among the other 69 patients with previous BC (median follow-up, 42 months), 14 developed ipsilateral or contralateral BC and 8 developed metastatic disease. Among the 16 patients without previous BC (median follow-up, 27 months), 3 developed BC. Of the 89 patients, 85 are still alive: 3 died from BC and 1 died from pancreatic cancer. No peritoneal malignancy was observed. CONCLUSIONS This study shows that prophylactic SO remains an important option for BRCA1/2 mutation carriers as asymptomatic ovarian/fallopian cancers were found in 4.5% of patients. However, a longer follow-up and larger series are required to more precisely evaluate the benefits of this procedure in terms of BC incidence, peritoneal malignancy, or recurrence.
