Abstract
The NCCN Guidelines for Genetic/Familial High-Risk Assessment: Breast, Ovarian, and Pancreatic focus primarily on assessment of pathogenic or likely pathogenic variants associated with increased risk of breast, ovarian, and pancreatic cancer and recommended approaches to genetic testing/counseling and management strategies in individuals with these pathogenic or likely pathogenic variants. This manuscript focuses on cancer risk and risk management for BRCA-related breast/ovarian cancer syndrome and Li-Fraumeni syndrome. Carriers of a BRCA1/2 pathogenic or likely pathogenic variant have an excessive risk for both breast and ovarian cancer that warrants consideration of more intensive screening and preventive strategies. There is also evidence that risks of prostate cancer and pancreatic cancer are elevated in these carriers. Li-Fraumeni syndrome is a highly penetrant cancer syndrome associated with a high lifetime risk for cancer, including soft tissue sarcomas, osteosarcomas, premenopausal breast cancer, colon cancer, gastric cancer, adrenocortical carcinoma, and brain tumors.

[PMID: 32943985 PMCID: PMC7487955 DOI: 10.1186/s12935-020-01500-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Accepted: 08/17/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND/AIMS The expression levels of long non-coding RNA XIST are significantly associated with paclitaxel (Pac) sensitivity in ovarian cancer, but the mechanism of action remains unclear. Therefore, this experimental design was based on lncRNA XIST analysis to regulate the effect of XIST on the tumor stem cell and paclitaxel sensitivity in ovarian cancer. METHODS Sphere assay and fluorescence activated cell sorting (FACS) were used to determine the expression levels of XIST and sensitivity to paclitaxel treatment. The effect of the proliferation was detected by MTT assay. Target gene prediction and screening, luciferase reporter assays were used to validate downstream target genes for lncRNA XIS and KMT2C. The expression of KMT2C was detected by RT-qPCR and Western blotting. RT-qPCR was used to detect the expression of cancer stem cell-associated genes SOX2, OCT4 and Nanog. The tumor changes in mice were detected by in vivo experiments in nude mice. RESULTS There was an inverse correlation between the expression of XIST and cancer stem cell (CD44 + /CD24-) population. XIST promoted methylation of histone H3 methylation at lysine 4 by enhancing the stability of lysine (K)-specific methyltransferase 2C (KMT2C) mRNA. XIST acted on the stability of KMT2C mRNA by directly targeting miR-93-5p. Overexpression of miR-93-5p can reverse the XIST overexpression-induced KMT2C decrease and sphere number increase. Overexpression of KMT2C inhibited XIST silencing-induced proliferation of cancer stem cells, and KMT2C was able to mediate paclitaxel resistance induced by XIST in ovarian cancer. The study found that XIST can affect the expression of KMT2C in the ovarian cancer via targeting miR-93-5p. CONCLUSION XIST promoted the sensitivity of ovarian cancer stem cells to paclitaxel in a KMT2C-dependent manner.

Gynecol Oncol 2020; 156:363-376. [PMID: 31918993 DOI: 10.1016/j.ygyno.2019.11.036] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 11/25/2019] [Accepted: 11/26/2019] [Indexed: 01/09/2023]
Abstract
OBJECTIVES Current risk-reducing salpingo-oophorectomy (RRSO) guidelines for individuals with BRCA1/2 mutations do not account for risk variability due to BRCA1/2 cluster region mutations that are associated with varying risks for the development of breast and ovarian cancer. We assessed whether current recommendations are appropriate for individual patients considering mutation-specific risks. METHODS Using a hypothetical cohort of patients with BRCA1/2 mutations, we constructed Markov models allowing for the estimation of mean life expectancy based upon BRCA1/2 mutation, the presence of a cluster region mutation (Ovarian Cancer Cluster Region (OCCR), Breast Cancer Cluster Region (BCCR), or non-BCCR/OCCR), age at time of BRCA1/2 diagnosis (20-65), and age at time of RRSO (21-80). RESULTS For all BRCA1/2 mutation types, the optimal strategy was to undergo RRSO as early as possible. For BRCA1/2 carriers who delayed RRSO or who were identified with a mutation later in life, the OCCR mutation tended to be associated with lower life expectancy estimates than the BCCR and non-BCCR/OCCR mutations. Minimal delays in RRSO (i.e., neighboring 5-year intervals) were associated with minor losses in life expectancy. Variables associated with greatest impact on life expectancy included ovarian cancer risk after RRSO, breast cancer mortality rate, non-cancer mortality associated with RRSO, and breast cancer stage distribution. CONCLUSIONS BRCA1/2 cluster regions may provide more precise estimates of life expectancy in counselling and shared decision-making. The most appropriate timing for RRSO is a complex decision and must be individualized for each patient.

Abstract
Background Risk-reducing salpingo-oophorectomy (RRSO) has been associated with approximately 50% breast cancer risk reduction among women with a pathogenic variant in BRCA1 or BRCA2 (BRCA1/2), a finding that has recently been questioned. Methods We estimated incidence rates of breast cancer and all cancers combined during 5 years of follow-up among participants selecting RRSO or ovarian cancer screening (OCS) among women with a BRCA1/2 pathogenic variant or strong breast and/or ovarian cancer family history. Ovarian or fallopian tube or peritoneal cancer incidence rates were estimated for the OCS group. Breast cancer hazard ratios (HRs) for time-dependent RRSO were estimated using Cox regression with age time-scale (4943 and 4990 women-years in RRSO and OCS cohorts, respectively). All statistical tests were two-sided. Results The RRSO cohort included 925 participants, and 1453 participants were in the OCS cohort (381 underwent RRSO during follow-up), with 88 incident breast cancers diagnosed. Among BRCA1/2 pathogenic variant carriers, a non-statistically significant lower breast cancer incidence was observed in the RRSO compared with the OCS cohort (HR = 0.86, 95% confidence interval = 0.45 to 1.67; P = .67). No difference was observed in the overall population or among subgroups stratified by prior breast cancer history or menopausal status. Seven fallopian tube and four ovarian cancers were prospectively diagnosed in the OCS cohort, and one primary peritoneal carcinoma occurred in the RRSO cohort. Conclusions These data suggest that RRSO might be associated with reduced breast cancer incidence among women with a BRCA1/2 pathogenic variant, although the effect, if present, is small. This evolving evidence warrants a thorough discussion regarding the impact of RRSO on breast cancer risk with women considering this intervention.

Abstract
Background The aim of this study was to explore the effect of dexmedetomidine (DEX)-mediated insulin-like growth factor 2 (IGF2) signal pathway on immune function and cancer cell invasion and migration in rats with ovarian cancer. Material/Methods Forty rats with ovarian cancer were divided into 4 groups: model group, and low dose (0.2 μg/kg/hour DEX), medium dose (1.0 μg/kg/hour DEX), and high dose (5.0 μg/kg/hour DEX) DEX groups. In addition, 10 Fischer344 rats were selected as a normal group. Human NUTU-19 poorly differentiated epithelial ovarian cancer cell line cells were divided into 4 groups: a blank group and low dose, medium dose, and high dose DEX NUTU-19 groups. Results Compared with the normal group, in the other groups the serum interleukin (IL)-2 and interferon gamma (INF-γ) levels, CD4+ and CD8+ percentages, CD4+/CD8+ ratio, and transformation rate of splenic lymphocytes were decreased, and the serum tumor necrosis factor alpha (TNF-α) level, IGF2, insulin-like growth factor 1 receptor (IGF1R), insulin receptor substrate 1 (IRS1) mRNA, and protein expressions in ovarian tissue were increased (all P<0.05). Results in the DEX groups compared with model group were the opposite of those in the other groups compared with normal group (all P<0.05). Compared with the blank group, in the other groups the proliferation, invasion, and migration of ovarian cancer cells were reduced significantly (all P<0.05). Compared with the low dose DEX NUTU-19 group, in the high dose DEX NUTU-19 group the invasion and migration of ovarian cancer cells weakened significantly (both P<0.05). Conclusions A certain dose of DEX can effectively inhibit IGF2 signal pathway activation to improve the immune function of rats with ovarian cancer, inhibiting the invasion and migration of ovarian cancer cells.

Abstract
Preclinical models are relatively underutilized and underfunded resources for modeling the pathogenesis and prevention of ovarian cancers. Several reviews have detailed the numerous published models of ovarian cancer. In this review, we will provide an overview of experimental model systems, their strengths and limitations, and use selected models to illustrate how they can be used to address specific issues about ovarian cancer pathogenesis. We will then highlight some of the preclinical prevention studies performed to date and discuss experiments needed to address important unanswered questions about ovarian cancer prevention strategies.

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

Abstract
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
OBJECTIVE To report the frequency and features of occult carcinomas and the incidence of subsequent cancers following risk-reducing salpingo-oophorectomy (RRSO) in BRCA mutation carriers. METHODS 257 consecutive women with germline BRCA mutations who underwent RRSO between January 1, 2000 and December 31, 2014 were identified in an Institutional Review Board approved study. All patients were asymptomatic with normal physical exams, CA 125 values, and imaging studies preoperatively, and had at least 12months of follow-up post-RRSO. All patients had comprehensive adnexal sectioning performed. Patient demographics and clinico-pathologic characteristics were extracted from medical and pathology records. RESULTS The cohort included 148 BRCA1, 98 BRCA2, 6 BRCA not otherwise specified (NOS), and 5 BRCA1 and 2 mutation carriers. Occult carcinoma was seen in 14/257 (5.4%) of patients: 9 serous tubal intraepithelial carcinomas (STIC), 3 tubal cancers, 1 ovarian cancer, and 1 endometrial cancer. Three patients (1.2%) with negative pathology at RRSO subsequently developed primary peritoneal serous carcinoma (PPSC), and 2 of 9 patients (22%) with STIC subsequently developed pelvic serous carcinoma. 110 women (43%) were diagnosed with breast cancer prior to RRSO, and 14 of the remaining 147 (9.5%) developed breast cancer following RRSO. Median follow-up of the cohort was 63months. CONCLUSION In this cohort, 5.4% of asymptomatic BRCA mutation carriers had occult carcinomas at RRSO, 86% of which were tubal in origin. The risk of subsequent PPSC for women with benign adnexa at RRSO is low; however, the risk of pelvic serous carcinoma among women with STIC is significantly higher.

Abstract
Women who are at increased risk of developing ovarian cancer because of their family history are encouraged to make decisions about the medical management of their cancer risk. Using data collected during interviews with 49 high-risk premenopausal women, this article looks at some of the influences on women’s risk-management choices. When describing their attitudes about preventative ovarian surgery, high-risk women draw upon discourses of control. Prophylactic surgery is constructed as both providing women with the means to gain control over their bodies, and as leading to a loss of control. More specifically, women perceive the removal of at-risk organs as both securing and undermining their present and future self-identities. Thus, it is argued that women’s willingness to undergo prophylactic ovarian surgery is dependent upon them negotiating various competing risks to self and body that are associated with this risk-management option.

Abstract
Ovarian cancer is the fourth leading cause of cancer among women and the number one gynecologic fatality. The etiology of ovarian cancer is still an enigma. Three common hypotheses under investigation include the ovulation, the pituitary gonadotropin, and the chronic inflammatory processes. Chemoprevention strategies used for ovarian cancer include oral contraceptives, aspirin and nonsteroidal anti-inflammatory agents, and retinoids. Surgical strategies are also used in the prevention of ovarian cancer. The primary treatment for patients with ovarian cancer is surgery with optimal tumor debulking, and for patients with advanced disease, this is followed by adjuvant chemotherapy. The standard practice is to follow surgery with six cycles of paclitaxel plus carboplatin. The second-line chemotherapy agents have had minimal long-term benefit for treating ovarian cancer. Hence, treatment with investigational agents remains the best option for patients with recurrent disease due to lack of alternative curative treatment.

Abstract
The aim of this study was to determine whether BRCA1 and BRCA2 mutation carriers have different baseline CA125 levels compared with non-carriers, and whether a significant difference in pre- and post-operative CA125 levels exists in BRCA mutation carriers undergoing risk-reducing bilateral salpingo-oophorectomy (RRBSO). The study also considered whether CA125 measurements should continue in unaffected BRCA mutation carriers after RRBSO. 383 Eligible women were identified through retrospective review of the BRCA Carrier Clinic at The Royal Marsden NHS Foundation Trust, London, UK. These women all had CA125 levels measured as they were either a carrier or at risk of a BRCA1 or BRCA2 mutation. Of these, 76 went on to have a negative predictive test for their familial mutation and so are classed as 'non-carriers'. 133 BRCA1 and 87 BRCA2 carriers had RRBSO, with a further 26 BRCA1 carriers, 28 BRCA2 carriers and one non-carrier developing ovarian cancer. The remaining 21 BRCA1 and 28 BRCA2 carriers did not have RRBSO or develop ovarian cancer in the time of study follow-up. CA125 levels were measured as surveillance or as part of pre-RRBSO care. CA125 measurement post-RRBSO was continued in 48 BRCA1 and 40 BRCA2 carriers. In 154 BRCA1 mutation carriers, the median baseline (i.e. before RRBSO and with no clinical signs of ovarian cancer) CA125 level was 9.0 U/ml (range 2-78) and was 10.0 U/ml (range 1-43) in 115 BRCA2 mutation carriers. When compared with the 75 non-carriers (median baseline CA125 10.0 U/ml; range 2-52), there was no significant difference between the BRCA1, BRCA2 and non-carrier groups. There was a significant reduction in CA125 from pre- to post-RRBSO in 48 BRCA1 carriers (p = 0.04) but no significant difference in 40 BRCA2 mutation carriers (p = 0.5). Out of a total of 220 mutation carriers who underwent RRBSO, two had an incidental ovarian cancer found on histopathology and another developed primary peritoneal cancer during the follow-up period. Our study is the first to compare initial serum CA125 levels in BRCA1 and BRCA2 mutation carriers with those of non-carriers. Our study found no significant difference between the three groups. A drop in CA125 levels after RRBSO in BRCA1 carriers supports the finding of earlier studies, but differed in that the fall was not seen in BRCA2 carriers. The finding of only one case of post-operative peritoneal cancer in 220 carriers undergoing RRBSO supports the discontinuation of post-RRBSO serum CA125 monitoring in BRCA mutation carriers.

Abstract
An understanding of the diagnosis and clinical management of hereditary breast and ovarian cancer syndrome (HBOC) is essential for obstetricians/gynecologists. This article provides practical information regarding collecting a family history, cancer risk assessment and genetic testing, BRCA-associated cancer prognosis and treatment, screening recommendations, and prevention strategies. Through appropriate cancer risk assessment, women with BRCA1/2 mutations can be identified, and screening and prevention strategies can be used before a diagnosis of cancer occurs. Women's health providers with a strong working knowledge of HBOC are able to improve the quality of care for women and families impacted by BRCA1/2 mutations.

Abstract
Since 2001, many studies by different investigators have demonstrated that the fallopian tube might be at the origin of most high-grade ovarian and peritoneal serous carcinomas. Simple changes in surgical practice (ie, prophylactic bilateral salpingectomy instead of salpingo-oophorectomy) could have significant implications for death from ovarian cancer and, on the other hand, for the morbidity caused by ovariectomy (surgical menopause). In this review, we describe the new tubal carcinogenic sequence, the advantages and disadvantages of exclusive use of salpingectomy in the general population, and in cases of hereditary predisposition to ovarian cancer such as for carriers of BRCA mutation.

Abstract
OBJECTIVE To evaluate the utility of peritoneal washing cytology (PWC) for detecting occult primary peritoneal carcinoma in patients with BRCA1 or BRCA2 mutations, we reviewed PWCs obtained during risk-reducing salpingo-oophorectomy (RRSO) from 117 patients at our institution and correlated the results with surgical pathology findings. METHODS Records of 128 PWCs from 125 patients with BRCA1 or BRCA2 mutations undergoing RRSO at MD Anderson Cancer Center between 2000 and 2010 were obtained. Slides were available for review for 119 PWCs from 117 patients (2 patients had 2 PWCs each). Cytopathologists, blinded to the RRSO histopathologic diagnoses, categorized the PWCs as benign, atypical, suspicious for malignancy, or malignant. These results were correlated with the RRSO histopathologic diagnoses. RESULTS PWCs from 113 patients were benign. Of the remaining 4 patients, 2 had PWCs classified as atypical, 1 as suspicious for malignancy, and 1 as malignant. The corresponding RRSO histopathologic findings of the 2 atypical PWCs showed endosalpingiosis and cystadenofibroma in one case and showed no abnormalities in the other case. Both patients with suspicious or malignant PWCs, indicating the possibility of occult peritoneal carcinoma, had RRSO histopathologic diagnoses of endometriosis and endosalpingiosis. Nine patients had abnormal tubal or ovarian histologic findings, but all 9 of these patients had benign PWCs. CONCLUSION PWC has the potential to detect occult peritoneal carcinoma in patients with BRCA1 or BRCA2 mutations. The clinical significance of a positive PWC without abnormal RRSO histology remains unclear and will require long-term follow-up for determination.

Abstract
BACKGROUND Women carriers of BRCA mutations often have occult malignancy found at the time of risk-reducing bilateral salpingo-oophorectomy (RRSO). We report outcomes in 111 consecutive BRCA-positive women who had RRSO using a rigorous surgical-pathological protocol from 1996 to 2008. METHOD We identified risk factors associated with finding an occult malignancy at RRSO with outcomes followed for a median of 61 months. RESULTS A total of 111 BRCA carriers elected RRSO, 10 patients [9.1%] had 14 sites of occult neoplasia. Two patients had invasive serous fallopian tube carcinoma (TSC) only, 1 patient had invasive serous ovarian carcinoma (OSC) only, 5 patients had tubal intraepithelial carcinoma (TIC) only, and 2 patients had multifocal lesions of the ovary (OSC) and TIC. Occult ovarian carcinomas were only detected in BRCA1 patients, and all BRCA2 carcinomas involved only the fallopian tube. The odds of finding occult carcinoma is 4 times greater (odds ratio, 4.3; 95% confidence interval, 1.06-20.7) in women older than 50 than in younger ones (P=0.023). A history of invasive breast cancer was associated with a reduced risk of occult carcinoma (odds ratio, 0.2; 95% confidence interval, 0.05-0.85). In median follow-up of 5 years, recurrence rate after detection of an occult carcinoma was 10% and the risk for primary peritoneal carcinoma was less than 1%. CONCLUSION A rigorous surgical protocol with meticulous pathologic review at RRSO yielded an overall detection rate of 9.1% for occult gynecological carcinoma in BRCA mutation carriers followed by a multidisciplinary team at a single institution. Primary peritoneal carcinoma after RRSO is rare.

Abstract
OBJECTIVES The objective of this study was to describe morphologic and immunohistochemical features of precursor tubal lesions in prophylactically removed Fallopian tubes. PATIENTS AND METHODS Hundred and forty-seven bilateral salpingectomies (genetic predisposition or group A: n=57; and control group or group B: n=90) were reviewed by two pathologists blinded to clinical data. Seven epithelial cytological and architectural features were studied to compare the degree of tubal epithelial abnormalities between the two groups. Immunohistochemical expression patterns of Ki67 and p53 were also evaluated. RESULTS Serous tubal intraepithelial lesions (STIL) have been identified in group A with stronger expression for Ki67 and p53 (especially in BRCA 1 group) than in group B. DISCUSSION AND CONCLUSION The current results show the importance of salpingo-oophrectomy in BRCA mutation carriers and the complete histopathological sampling of the Fallopian tubes.

Abstract
BACKGROUND Optical imaging systems are robust, portable, relatively inexpensive, and have proven utility in detecting precancerous lesions in the lung, esophagus, colon, oral cavity and cervix. We describe the use of light-induced endogenous fluorescence (autofluorescence) in identifying preinvasive and occult carcinomas in ex vivo samples of human fallopian tube (FT) epithelium. METHODS Women undergoing surgery for an i) ovarian mass, ii) a history suggestive of hereditary breast-ovarian cancer, or iii) known serous ovarian cancer following neoadjuvant chemotherapy (NAC) were approached for informed consent. Immediately following surgery, FT's were photographed in reflectance and fluorescence at high resolution. Images included: (1) white-light reflectance of luminal/epithelial surface; (2) narrow-band green reflectance (570 nm) (3) green autofluorescence (405/436 nm excitation); and (4) blue autofluorescence (405 nm excitation). Areas revealing a loss of natural tissue fluorescence or marked increase in tissue microvasculature were recorded and compared to final histopathologic diagnosis (SEE-FIM protocol). RESULTS Fifty-six cases involving one or both fallopian tubes underwent reflectance and fluorescence visualization. Nine cases were excluded, either secondary to non-ovarian primary pathology (7) or excessive trauma (2) rendering tissue interpretation impossible. Of the 47 cases remaining, there were 11 high grade serous (HGS) and 9 non-serous ovarian carcinomas undergoing primary debulking surgery, 5 serous carcinomas having received NAC, 8 benign ovarian tumors, and 14 women undergoing risk-reducing bilateral salpingo-oophorectomy (RRBSO). Methodology was feasible, efficient, and reproducible. TIC or carcinoma was identified in 7/11 HGS, 3/5 NAC, and 1/14 RRBSO. Optical images were reviewed to determine test positive or negative based on standardized criteria. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for the entire cohort (73%; 83%; 57%; 91%) and in a subgroup that excluded non-serous histology (87.5%; 92%; 78%; 96%). CONCLUSIONS Abnormal FT lesions can be identified using ex vivo optical imaging technologies. With this platform, we will move towards genomic interrogation of identified lesions, and developing in vivo screening modalities via falloposcopy.

Abstract
OBJECTIVE Microscopic structures lined by müllerian epithelium are frequently seen outside the uterus and fallopian tubes and are termed "müllerian rests" or "secondary müllerian system." Varied entities ranging from benign endosalpingosis to highly malignant ovarian tumors are thought to be derived from the secondary müllerian system. Cross-sectional imaging findings of diseases and disorders of the secondary müllerian system are presented here. CONCLUSION Familiarity with a wide spectrum of diseases and disorders of the secondary müllerian system allows accurate diagnosis and management.

Abstract
OBJECTIVE Although perceived control and coping have been studied across various health conditions, these relationships have been less well studied in the context of coping with cancer risk over time. The present study was a longitudinal study of the effects of perceived control and problem-focused coping on changes in psychological adjustment and behavioural outcomes among women at increased risk for ovarian cancer. DESIGN AND METHODS Eighty women enrolled in a familial cancer risk assessment programme participated in this study. Assessments of problem-focused coping, perceived control and distress were collected upon entry into the programme and again at 3-month follow-up. Behavioural adherence to screening during the 12-month period following programme entry was obtained from clinic records. RESULTS Using hierarchical regression analysis, we observed a significant interaction between perceived control and problem-focused coping for psychological distress, beta=0.94, p<.05. Specifically, problem-focused coping was associated with increasing distress over time among women who perceived high control. A significant control by coping interaction was also observed for behavioural adherence to pelvic ultrasound and CA125 screening, such that women who perceived high control and utilized problem-focused coping were less likely to undergo screening. CONCLUSIONS Under conditions of high perceived control, problem-focused coping was associated with increasing distress as well as poorer behavioural adherence. Thus, perceived control and problem-focused coping may not always yield positive psychological or behavioural health outcomes. These findings contribute to a greater understanding of how problem-focused coping and perceived control may influence the course of adjustment to cancer risk over time.

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
BRCA1 and BRCA2 mutation carriers have a 54-85% and 45% lifetime risk of developing breast cancer, respectively, and a 18-60% and 11-27% lifetime risk of developing ovarian cancer, respectively. Oral contraceptives (OCs) significantly reduce the risk of ovarian cancer also in BRCA1/BRCA2 mutation carriers. The association between OC use and breast cancer risk in these women is controversial. Some studies showed a modestly increased risk especially among BRCA1 mutation carriers. The risk appears to be greater for women who took OCs for at least 5 years and who took OCs before the age of 30 years. Other studies reported that duration of use before first full-term pregnancy has a positive association with breast cancer risk. Salpingo-oophorectomy reduces the risk of coelomic epithelial cancer of 80-95% and the risk of breast cancer of approximately 50%. BRCA1 and BRCA2 mutation carriers should be encouraged to undergo prophylactic bilateral salpingo-oophorectomy at the age of 35-40 years or when childbearing is complete. Short-term use of hormone replacement therapy may relieve menopausal symptoms and does not appear to affect the breast cancer risk reduction obtained with salpingo-oophorectomy.

Abstract
Cancers of the reproductive organs (i.e., ovaries, uterus and testes), like other cancers, occur as a result of a multi-stage interaction of genetic and environmental factors. A small proportion of cancers of the reproductive organs occur as part of a recognised cancer syndrome, as a result of inheritance of mutations in highly penetrant cancer susceptibility genes (e.g., BRCA1, BRCA2, MLH1 or MSH2). Recognition of individuals and families with inherited cancer predisposition syndromes and individuals at high risk due to familial cancer clustering is fundamentally important for the management and treatment of the current cancer and for future prevention of further cancers for the individual and their extended family.

Abstract
Risk-reducing salpingo-oophorectomy is currently advocated for the reduction of both breast and ovarian cancer risk in BRCA1/2 carriers, but residual risk of peritoneal primary cancer remains a concern. A sequential series of women attending a single institution for ovarian risk management underwent either risk-reducing surgery or screening. A person-years at risk analysis was used to compare observed versus expected cancers. In total, 300 women underwent risk-reducing salpingo-oophorectomy, including 160 BRCA1/2 mutation carriers. Three occult ovarian cancers were detected at surgery. There have been 2400.4 years of follow-up and 15.79 expected cancers. No peritoneal cancers have occurred. Amongst 503 women controls with 3444.3 years of follow-up, 15.93 ovarian cancers were expected and 17 were found. There were six ovarian cancer-related deaths in the control group compared with one in the surgery group. Risk-reducing salpingo-oophorectomy in a single institution has so far avoided peritoneal cancer incidence.

Abstract
To overcome the significant mortality associated with ovarian cancer, a highly sensitive and specific screening test is urgently needed. CA-125 testing is used to monitor response to chemotherapy, detect recurrence, and detect late stage ovarian cancer. However, CA-125 testing, alone or in combination with ultrasonography, has not been adequate for early detection of ovarian cancer. This article discusses the authors' recent report of a novel multiplex assay that uses a panel of six serum biomarkers: leptin, prolactin, osteopontin, insulin-like growth factor II (IGF-II), macrophage inhibitory factor (MIF), and CA-125. The combination of these six proteins yielded 95.3% sensitivity and 99.4% specificity. The application of this test in the clinical context and the most appropriate population, which could benefit from the test, are discussed.

Abstract
Ovarian epithelial dysplasia has been described in the ovarian surface epithelium by histologic, morphometric and nuclear profile studies. It could represent a potential precursor of ovarian malignancy in patients with genetic risk of ovarian cancer, although its natural history and progression to carcinoma are unpredictable. Diagnosis and identification of ovarian dysplasia would certainly be useful to understand the early steps of ovarian carcinogenesis.

Abstract
At least 10% of ovarian tumors are hereditary and associated with highly penetrant, autosomal, dominant genetic predisposition. Three clinical manifestations of hereditary ovarian cancer have been identified: site-specific ovarian cancer, hereditary breast and/or ovarian cancer (HBOC) and hereditary non-polyposis colorectal cancer (HNPCC) syndromes. BRCA germline mutations account for more than 90% of all hereditary epithelial ovarian tumors whereas most of the remaining 10% are caused by MLH1 and MSH2 mutations, which are susceptibility genes of HNPCC. Genetic testing is available for each of the three hereditary syndromes above mentioned. The recommendations for OC surveillance in high-risk women having a strong family history or BRCA mutation carriers include transvaginal pelvic ultrasound with color Doppler and serum CA125 every 6 months. Bilateral salpingo-oophorectomy appears to be effective to reduce the risk of ovarian cancer in BRCA mutation carriers. Hysterosalpingo-oophorectomy should be considered in HNPCC women who undergo surgery for colorectal carcinoma.

Abstract
BACKGROUND Women with Lynch syndrome (hereditary nonpolyposis colorectal cancer) have an increased lifetime risk for endometrial and ovarian cancer. Screening and prophylactic surgery have been recommended as prevention strategies. In this study, the authors estimated the net health benefits and cost-effectiveness of these strategies in a Markov decision-analytic model. METHODS Five strategies were compared for a hypothetical cohort of women with Lynch syndrome: 1) no prevention ('reference'); 2) prophylactic surgery (hysterectomy and bilateral salpingo-oophorectomy) at age 30 years; 3) prophylactic surgery at age 40 years; 4) annual screening with endometrial biopsy, transvaginal ultrasound, and CA 125 from age 30 years; and 5) annual screening from age 30 years until prophylactic surgery at age 40 years (combined strategy). Net health benefit was measured in quality-adjusted life years (QALYs), and the primary outcome measured was the incremental cost-effectiveness ratio (ICER). Baseline and transition probabilities were obtained from published literature, and costs were from the U.S. Department of Health and Human Services and Agency for Health Care Quality and Research. Sensitivity analyses were performed for uncertainty around various parameters. RESULTS The combined strategy provided the highest net health benefit (18.98 QALYs) but had an ICER of $194,650 per QALY relative to the next best strategy (prophylactic surgery at age 40 years). Prophylactic surgery at age 30 years and annual screening were dominated by alternate strategies. CONCLUSIONS Annual screening followed by prophylactic surgery at age 40 years was the most effective gynecologic cancer prevention strategy, but the incremental benefit over prophylactic surgery alone was attained at substantial cost. The ICER would become favorable by improving the effectiveness and reducing the costs of screening in this population.

Abstract
BACKGROUND Women who are genetically predisposed to ovarian cancer are at very high risk of developing this disease. Although risk-reducing salpingo-oophorectomy (RRSO) and various screening regimens are currently recommended to reduce ovarian cancer risk, the optimal management strategy has not been established nor have multiple additional issues been adequately addressed. We developed a collaboration among the Clinical Genetics Branch (National Cancer Institute's Intramural Research Program), the Gynecologic Oncology Group (GOG), and the Cancer Genetics Network to address these issues. METHODS This is a prospective, international, two-cohort, nonrandomized study of women at genetic risk of ovarian cancer, who chose either to undergo RRSO or screening, at study enrollment. Primary study objectives include quantifying and comparing ovarian and breast cancer incidence in the two study groups, assessing feasibility and selected performance characteristics of a novel ovarian cancer screening strategy (the Risk of Ovarian Cancer Algorithm), evaluating various aspects of quality of life and nononcologic morbidity related to various interventions in at-risk women, and creating a biospecimen repository for subsequent translational research. RESULTS Study accrual is complete as of November 2006; 2,605 participants enrolled: 1,030 (40%) into the surgical cohort and 1,575 (60%) into the screening cohort. Five years of prospective follow-up ends in November 2011. Verification of BRCA mutation carrier status is under way, either through patient-provided reports from clinical genetic testing done before enrollment or through research-based genetic testing being conducted as part of the protocol. Patient eligibility is currently under evaluation and baseline, surgical, pathology, and outcome data are still being collected. The study design and selected baseline characteristics of cohort members are summarized. CONCLUSION This National Cancer Institute intramural/extramural collaboration will provide invaluable prospectively collected observational data on women at high familial ovarian cancer risk, including substantial numbers of women carrying BRCA1/2 mutations. These data will aid in elucidating the effect of RRSO on breast/ovarian cancer risk and the effects of two management strategies, on quality of life and other issues that may influence patient care, as well as providing preliminary estimates of test specificity and positive predictive value of a novel ovarian cancer screening strategy.

Abstract
Metachronous papillary serous carcinoma of the peritoneum (PSCP) after endometrial carcinoma (EC) is an extremely rare condition. Only three patients have been reported in the English literature. We present the fourth patient who had a more aggressive and fatal clinical course. A 79-year-old multiparous woman complained of progressive abdominal pain and distension after 5 years, subsequent to total abdominal hysterectomy and bilateral salpingo-oophorectomy for endometrioid type EC. Serum CA-125 level being followed routinely rose above 500 IU/mL. Abdominal and pelvic computed tomography demonstrated ascites, omental thickening, and nodularity. Paracentesis showed malignant cells resembling papillary adenocarcinoma. Omentectomy and bilateral pelvic lymphadenectomy were performed as cytoreductive surgery. The histologic slides of the totally sampled ovaries obtained from the first operation were reexamined and the corresponding paraffin blocks were re-sectioned but no tumor was detected. The microscopic appearance of the tumor in the omentum differed from that of the previous EC. Immunohistochemically, while the tumor showed reactivity for low and high molecular weight cytokeratin (CK) cocktail, epithelial membrane antigen, CK7, CA-125, and Ber-EP4, the immunostains for calretinin, monoclonal carcinoembryonic antigen, and CK20 were negative. On the basis of these results and the criteria proposed by the Gynecologic Oncology Group, the tumor was diagnosed as metachronous PSCP developed after EC, which corresponded to stage IIIC according to FIGO criteria for ovarian carcinoma. The patient received two cycles of carboplatin and paclitaxel and died 2 months after the cytoreductive surgery.

Abstract
Background Women that carry germ-line mutations for BRCA1 or BRCA2 genes are at an increased risk of developing breast, ovarian and peritoneal cancer. Primary peritoneal carcinoma is a rare tumour histologically identical to papillary serous ovarian carcinoma. Risk-reducing surgery in the form of mastectomy and oophorectomy in premenopausal women has been recommended to prevent breast and ovarian cancer occurrence and decrease the risk of developing primary peritoneal cancer. Case presentation We present a case report of a woman with a strong family history of breast cancer who underwent risk-reducing surgery in the form of bilateral salpingo-oophorectomy following a mastectomy for a right-sided breast tumour. Following the finding of a BRCA1 mutation, a prophylactic left-sided mastectomy was performed. After remaining well for twenty-seven years, she presented with rectal bleeding and altered bowel habit, and was found to have a secondary cancer of the sigmoid colon. She was finally diagnosed with primary papillary serous carcinoma of the peritoneum (PSCP). Conclusion PSCP can present many years after risk-reducing surgery and be difficult to detect. Surveillance remains the best course of management for patients with known BRCA mutations.

Abstract
Women with mutations in BRCA1 or BRCA2 are at tremendously increased lifetime risk of both breast and BRCA-associated gynecologic (ovarian, fallopian tube, and primary peritoneal) cancer. Because of limitations in the efficacy of available screening and chemopreventive approaches for women with a mutation in one of these genes, surgical risk reduction, particularly risk-reducing salpingo-oophorectomy (RRSO), has become an important component of the management options in hereditary breast-ovarian cancer syndrome. This article will review the rationale and efficacy of RRSO for prevention of breast and BRCA-associated gynecologic cancer. Surgical technique and methods of pathologic evaluation will be presented. Controversies regarding uterine preservation and post-RRSO hormone replacement therapy will be addressed. Considerations that may impact the appropriate timing of the procedure will be reviewed, and the potential role of RRSO in BRCA-negative hereditary breast cancer families will also be discussed.

Abstract
Genetic counseling and testing for inherited disorders are part of every obstetrician-gynecologist's practice. Family history, ethnicity, and race are routinely evaluated as a part of the prenatal assessment. The discovery of genes responsible for inherited cancer susceptibility and the wide availability of clinical genetic testing for mutations in these genes have made similar assessments an integral part of gynecologic practice as well. The indications for genetic testing for mutations in BRCA1, BRCA2, and the mismatch repair genes responsible for the hereditary nonpolyposis colon cancer (HNPCC) syndrome need to be individualized. As in obstetrics, genetic counseling can provide critical assessment of the family history to help determine the likelihood of an inherited cancer susceptibility syndrome and the appropriateness of genetic testing. The subsequent clinical recommendations for mutation carriers need to take into account the patient's age, desire for future childbearing, and other medical history when prescribing screening interventions or prophylactic surgery. Practical applications of genetic testing for cancer susceptibility have the ability to reduce the burden of hereditary cancers by saving lives, decreasing medical morbidities, and reducing psychological stress.

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.

Abstract
BACKGROUND A significant portion of cancers are accounted for by a heritable component, which has increasingly been linked to mutations in specific genes. Clinical interventions have been formulated for mutation carriers within affected families. The primary interventions for mutation carriers of highly penetrant syndromes are surgical. METHODS The American Society of Clinical Oncology and the Society of Surgical Oncology formed a task force charged with presenting an educational symposium on surgical management of hereditary cancer syndromes at annual society meetings, and this resulted in a position paper on this topic. The content of both the symposium and the position paper was developed as a consensus statement. RESULTS This article addresses hereditary breast, colorectal, ovarian/endometrial, and multiple endocrine neoplasias. A brief introduction on the genetics and natural history of each disease is provided, followed by detailed descriptions of modern surgical approaches, clinical and genetic indications, timing of prophylactic surgery, and the efficacy of surgery (when known). Although several recent reviews have addressed the role of genetic testing for cancer susceptibility, this article focuses on the issues surrounding surgical technique, timing, and indications for surgical prophylaxis. CONCLUSIONS Risk-reducing surgical treatment of hereditary cancer is a complex undertaking. It requires a clear understanding of the natural history of the disease, realistic appreciation of the potential benefits and risks of these procedures in potentially otherwise healthy individuals, and the long-term sequelae of such interventions, as well as the individual patient's and family's perceptions of surgical risk and anticipated benefit.

Abstract
The cancer susceptibility genes BRCA1 and BRCA2 appear to be responsible for virtually all hereditary breast ovarian families, and a smaller subset of hereditary site-specific breast cancer families. Fortunately, effective strategies have been developed to reduce the risk for the development of breast and ovarian cancer in women with BRCA1/2 mutations, making genetic testing for these mutations an important part of the management at women with a strong family history of these diseases. Here, we review the current evidence for risk reduction strategies and outline future research directions.
