Abstract
The diagnosis of synchronous carcinomas, involving both the endometrium and ovaries, is not a rare finding in gynecologic pathology and represents a challenge with implications on tumor staging and therapeutic decision-making. A mono-institutional series of 11 metastatic and 6 paired synchronous endometrial and ovarian carcinomas were reviewed by 2 expert pathologists based on previously published histopathologic criteria. The series was investigated for DNA mismatch repair proteins, p53, and POLE status and was subject to DNA-based next-generation sequencing targeting 67 cancer-related genes. Out of 17 pairs, 16 featured the same histotype (10 endometrioid, 4 serous high-grade, and 2 clear cells). By using WHO 2020 criteria, 11 couples of tumors were confirmed as metastatic and 6 couples were confirmed as independent. Based on next-generation sequencing analysis, 16 of 17 cases (11 metastatic and 5 independent) of our series showed evidence of a clonal relationship between endometrial and ovarian carcinomas. In metastatic cases, the adverse outcome was associated with nonendometrioid/high-grade endometrioid histotype and with the p53-abnormal molecular subtype. Four cases originally fulfilling clinicopathological criteria of independent endometrial and ovarian carcinomas were clonally related, low-grade endometrioid histotype and POLE -mut, mismatch repair deficient, and no specific molecular profile molecular subtypes; no adverse event was recorded in this group. In summary, the molecular characterization of synchronous gynecologic carcinomas confirms their clonal origin in most cases. However, the results of our study point out that the clinical behavior of these tumors seems to be determined by the presence of high-risk WHO 2020 histologic criteria and molecular features (i.e. p53-abnormal), rather than the monoclonal origin.

Abstract
Next-generation sequencing (NGS) studies have demonstrated that co-occurring sporadic endometrioid endometrial carcinoma (EEC) and endometrioid ovarian carcinoma (EOC) are clonally related, suggesting that they originate from a single primary tumor. Despite clonality, synchronous EEC and EOC when diagnosed at early stage behave indolently, similar to isolated primary EEC or isolated primary EOC. In the present study, we compared the DNA methylation signatures of co-occurring EEC and EOC with those of isolated primary EEC and isolated primary EOC. We also performed targeted NGS to assess the clonal relatedness of 7 co-occurring EEC and EOC (4 synchronous EEC and EOC and 3 metastatic EEC based on pathologic criteria). NGS confirmed a clonal relationship in all co-occurring EEC and EOC. DNA methylation profiling showed distinct epigenetic signatures of isolated primary EEC and isolated primary EOC. Endometrial tumors from co-occurring EEC and EOC clustered with isolated primary EEC while their ovarian counterparts clustered with isolated primary EOC. Three co-occurring EEC and EOC cases with peritoneal lesions showed a closer epigenetic signature and copy number variation profile between the peritoneal lesion and EOC than EEC. In conclusion, synchronous sporadic EEC and EOC are clonally related but demonstrate a shift in DNA methylation signatures between ovarian and endometrial tumors as well as epigenetic overlap between ovarian and peritoneal tumors. Our results suggest that tumor microenvironment in the ovary may play a role in epigenetic modulation of metastatic EEC.

Abstract
Epithelial ovarian carcinoma (EOC) is known for high mortality due to diagnosis at advanced stages and frequent therapy resistance. Previous findings suggested that the DNA repair system is involved in the therapeutic response of cancer patients and DNA repair genes are promising targets for novel therapies. This study aimed to address complex inter-relations among gene expression levels, methylation profiles, and somatic mutations in DNA repair genes and EOC prognosis and therapy resistance status. We found significant associations of DUT expression with the presence of peritoneal metastases in EOC patients. The high-grade serous EOC subtype was enriched with TP53 mutations compared to other subtypes. Furthermore, somatic mutations in XPC and PRKDC were significantly associated with worse overall survival of EOC patients, and higher FAAP20 expression in platinum-resistant than platinum-sensitive patients was observed. We found higher methylation of RAD50 in platinum-resistant than in platinum-sensitive patients. Somatic mutations in BRCA1 and RAD9A were significantly associated with higher RBBP8 methylation in platinum-sensitive compared to platinum-resistant EOC patients. In conclusion, we discovered associations of several candidate genes from the DNA repair pathway with the prognosis and platinum resistance status of EOC patients, which deserve further validation as potential predictive biomarkers.

Abstract
The move toward consistent and comprehensive surgical pathology reports for cancer resection specimens has been a key development in supporting evidence-based patient management and consistent cancer staging. The International Collaboration on Cancer Reporting (ICCR) previously developed a data set for reporting of the ovarian, fallopian tube and primary peritoneal carcinomas which was published in 2015. In this paper, we provide an update on this data set, as a second edition, that reflects changes in the 2020 World Health Organization (WHO) Classification of Female Genital Tumours as well as some other minor modifications. The data set has been developed by a panel of internationally recognized expert pathologists and a clinician and consists of "core" and "noncore" elements to be included in surgical pathology reports, with detailed commentary to guide users, including references. This data set replaces the widely used first edition, and will facilitate consistent and accurate case reporting, data collection for quality assurance and research, and allow for comparison of epidemiological and pathologic parameters between different populations.

Abstract
Abstract
Background
Endometriosis is assumed to be involved in ovarian cancer development, which is called endometriosis-associated ovarian cancer (EAOC). Uterine endometrial cells may be the cell of origin of EAOC. Accumulated carcinogenic changes in the uterine endometrial cells may increase the risk of developing EAOC. To further understand the pathogenesis of EAOCs, we focused on the clinicopathological characteristics of EAOCs in endometrial cancer patients with concomitant endometriosis.
Methods
We retrospectively reviewed 376 patients who were surgically treated for stage I–III endometrial cancer. Clinicopathological characteristics were compared between patients with and without endometriosis. Furthermore, the incidence of simultaneous endometrial and ovarian cancer (SEOC) and the histological characteristics of SEOC were compared between the two groups.
Results
Among 376 patients with endometrial cancer, 51 had concomitant endometriosis. Patients with endometriosis were significantly younger and more frequently had endometrioid G1/G2 tumors than those without endometriosis. The incidence of SEOCs was significantly higher in endometrial cancer patients with endometriosis than those without it (p < 0.0001); notably, 12 of 51 endometrial cancer patients with endometriosis (24%) had SEOCs. All of the ovarian cancers in endometrial cancer patients with endometriosis were endometrioid carcinomas. Moreover, even in those without endometriosis, endometrioid carcinoma was the most common histological type of SEOC.
Conclusion
We revealed that endometrial cancer patients with endometriosis had a high probability of SEOC and that endometrioid carcinoma was the most common histological subtype of SEOC regardless of the presence of endometriosis. For patients with endometrial cancer and endometriosis, careful examination of ovarian endometriotic lesions may be important to detect EAOCs.

Abstract
AIM Lynch syndrome (LS) is one of the most common hereditary cancer syndromes, characterized by mutations in mismatch repair genes and autosomal dominant inheritance. Women with LS have an additional increased risk of gynecologic malignancies, including endometrial cancer (EC) and ovarian cancer (OC). Compared with EC, OC is relatively under investigation. This review thoroughly summarizes the current clinical evidence of surveillance, screening, and prevention strategies, and describes the molecular and clinical characteristics of LS-associated OC. METHODS An electronic search from databases of PubMed and Google Scholar was carried out using key words pertaining to Lynch syndrome and ovarian cancer. A review of the literatures including review articles, experimental, and observational studies published between 2000 and 2021 was conducted. RESULTS The lifetime risk of OC in women with LS of MLH1, MSH2, and MSH6 mutations is approximately 7%, with the median age at onset being 46 years, 10-15 years earlier than that in sporadic cases. Histologically, LS-associated OCs are primarily endometrioid (40%), high-grade (25%), and low-grade (11%) serous, or clear cell (6%) in nature. Eighty-five percent of patients are diagnosed at an early stage, presenting with a good prognosis at 84% 5-year survival. Optimal screening strategies for OC in LS are controversial; combined screening of patients' clinical and family history, immunohistochemical analysis, and microsatellite instability testing for mismatch repair deficiency have been proven efficient. CONCLUSION The clinical features were different between ovarian cancer in Lynch syndrome and sporadic cases. More research are needed for a greater understanding of the prevention and medical treatment of LS-associated OC.

Abstract
Lynch syndrome patients with synchronous endometrial and ovarian cancer (SEOC) are rare. When these cases occur, they are most often endometrioid histology and early grade. Early-grade tumors are not often sent for somatic tumor profiling. We present a 39 year old SEOC patient with germline PMS2 Lynch syndrome and clinical tumor analysis leading to insight regarding the origin and cause of these tumors, with potential therapy options. PMS2-related SEOC is less common due to lower risks for these cancers associated with germline PMS2 mutation compared to other Lynch genes. While synchronous cancers are not common, they are more likely to occur with Lynch syndrome. Tumor profiling with next-generation sequencing of 648 genes identified sixteen shared somatic actionable and biologically relevant mutations. This case is a rare example of a patient with PMS2 germline Lynch syndrome with shared somatic variants that demonstrate clonality of the two tumors arising from one common site.

Abstract
Ovarian cancer is one of the most common gynecologic cancers that has the highest mortality rate. Endometrioid ovarian cancer, a distinct subtype of epithelial ovarian cancer, is associated with endometriosis and Lynch syndrome, and is often accompanied by synchronous endometrial carcinoma. In recent years, dysbiosis of the microbiota within the female reproductive tract has been suggested to be involved in the pathogenesis of endometrial cancer and ovarian cancer, with some specific pathogens exhibiting oncogenic having been found to contribute to cancer development. It has been shown that dysregulation of the microenvironment and accumulation of mutations are stimulatory factors in the progression of endometrioid ovarian carcinoma. This would be a potential therapeutic target in the future. Simultaneously, multiple studies have demonstrated the role of four molecular subtypes of endometrioid ovarian cancer, which are of particular importance in the prediction of prognosis. This literature review aims to compile the potential mechanisms of endometrioid ovarian cancer, molecular characteristics, and molecular pathological types that could potentially play a role in the prediction of prognosis, and the novel therapeutic strategies, providing some guidance for the stratified management of ovarian cancer.

Clonal relationship and directionality of progression of synchronous endometrial and ovarian carcinomas in patients with DNA mismatch repair-deficiency associated syndromes. Mod Pathol 2021; 34:994-1007. [PMID: 33328602 PMCID: PMC8076061 DOI: 10.1038/s41379-020-00721-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Revised: 10/25/2020] [Accepted: 10/26/2020] [Indexed: 01/01/2023]
Abstract
Sporadic synchronous endometrial (ECs) and ovarian cancers (OCs), although clinically considered to be independent primaries, have been shown to be clonally related and likely constitute metastases from each other. We sought to define whether synchronous ECs/OCs in patients with DNA mismatch repair (MMR)-deficiency syndromes would be clonally related. We subjected synchronous ECs/OCs from four patients (LS3-LS6) with clinically confirmed Lynch syndrome (LS) and one patient with constitutional mismatch repair-deficiency syndrome (CMMRD) to massively parallel sequencing targeting 468 cancer-related genes. Somatic mutations, copy number alterations (CNAs), clonal relatedness and clonal decomposition analyses were performed using previously described bioinformatics methods. All synchronous ECs/OCs analyzed were considered independent primaries based on clinicopathologic criteria. Sequencing analysis revealed that the ECs/OCs of three cases (LS2-CMMRD, L3, L4) harbored similar repertoires of somatic mutations and CNAs and were clonally related. In these three cases, a subset of subclonal mutations in the EC became clonal in the OC, suggesting that the EC was likely the substrate from which the OC developed. LS5's EC/OC had distinct mutational profiles but shared specific CNAs. In contrast, LS6's EC/OC harbored distinct somatic mutations and lacked CNAs, consistent with each tumor constituting an independent primary lesion. In LS5 and LS6, PTEN mutations and PTEN loss of protein expression were found to be restricted to the EC. Finally, re-analysis of sequencing data of sporadic synchronous ECs/OCs supported the observations made in the current study that the directionality of progression is likely from the endometrium to the ovary. In conclusion, contrary to sporadic synchronous ECs/OCs, which are almost invariably clonally related, ECs/OCs simultaneously involving the uterus and ovary in LS patients may represent distinct primary tumors. A subset of MMR-deficiency syndrome-related synchronous ECs/OCs, however, may originate from a single primary tumor at variance with their clinical diagnosis, with the endometrium being the likeliest site of origin.

Abstract
OBJECTIVE While disparities in endometrial hyperplasia and endometrial cancer are well documented in Blacks and Whites, limited information exists for Hispanics. The objective is to describe the patient characteristics associated with endometrial hyperplasia symptoms, endometrial hyperplasia with atypia and endometrial cancer, and assess factors contributing to racial/ethnic differences in disease outcomes. METHODS This single-center, retrospective study included women aged ≥50 years with ≥ two encounters for endometrial hyperplasia symptoms, endometrial hyperplasia with atypia and endometrial cancer between 2012 and 2016. Multivariate logistic regression models evaluated the predictors of endometrial cancer and hyperplasia. RESULTS We included 19,865 women (4749 endometrial hyperplasia symptoms, 71 endometrial hyperplasias with atypia, 201 endometrial cancers) with mean age of 60.45 years (SD 9.94). The odds of endometrial hyperplasia symptoms were higher in non-Hispanic Blacks (Odds Ratio [OR] 1.56, 95% Confidence Interval [CI] 1.20-1.72), Hispanics (OR 1.35, 95% CI 1.22-1.49), family history of female cancer (OR 1.25, 95% CI 1.12-1.39), hypertension (OR 1.24, 95% CI 1.14-1.35), and birth control use (OR 1.29, 95% CI 1.15-1.43). Odds of endometrial cancer and atypical hyperplasia increased for ages 60-64 (OR 7.95, 95% CI 3.26-19.37; OR 3.66, 95% 1.01-13.22) and being obese (OR 1.61, 95% CI 1.08-2.41; OR: 6.60, 95% CI 2.32-18.83). Odds of endometrial cancer increased with diabetes (OR 1.68, 95% CI 1.22-2.32). CONCLUSION(S) Patients with obesity and diabetes had increased odds of endometrial cancer and hyperplasia with atypia. Further study is needed to understand the exogenous estrogen effect contributing to the increased incidence among Hispanics.

Abstract
Background and objective The incidence of synchronous primary endometrial and ovarian cancer is uncommon and poses a diagnostic challenge to the treating physician about their origin as either primary or metastasis. The purpose of this study was to evaluate the clinicopathological behavior, treatment modality-related outcomes, and prognosis related to primary endometrial and ovarian cancers at a tertiary care referral center in South Asia. Methods We retrospectively analyzed 30 patients with synchronous ovarian and endometrial cancers treated at Shaukat Khanum Memorial Cancer Hospital and Research Centre in Lahore, Pakistan from January 2005 to August 2017. Results The median age of the patients at the time of diagnosis was 51 years (range: 25-72 years). The common presenting symptoms were irregular uterine bleeding (30%), post-menopausal bleeding (26.7%), abdominal mass (16.7%), and abdominal pain (26.7%). Endometrial adenocarcinoma type was the most common histological variant found among the participants: 90% (n=27) of uterine and 56.7% (n=17) of ovarian cancers. All patients underwent surgical intervention. Among them, 25 patients received platinum-based adjuvant chemotherapy, four received neoadjuvant chemotherapy, and 18 received adjuvant radiotherapy. The early-stage group [International Federation of Gynecology and Obstetrics (FIGO) stage I and II] had a more favorable prognosis than the advanced stage group (FIGO stages III and IV). Conclusion Based on our findings, patients with synchronous primary endometrial and ovarian cancers have better overall survival rates than patients with single primary ovarian or endometrial cancers. Also, synchronous primary endometrial and ovarian cancer endometroid types have better overall survival than patients with non-endometrioid or mixed histologic types.

DNA Repair and Ovarian Carcinogenesis: Impact on Risk, Prognosis and Therapy Outcome. Cancers (Basel) 2020; 12:cancers12071713. [PMID: 32605254 PMCID: PMC7408288 DOI: 10.3390/cancers12071713] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 06/24/2020] [Indexed: 12/13/2022] Open
Abstract
There is ample evidence for the essential involvement of DNA repair and DNA damage response in the onset of solid malignancies, including ovarian cancer. Indeed, high-penetrance germline mutations in DNA repair genes are important players in familial cancers: BRCA1, BRCA2 mutations or mismatch repair, and polymerase deficiency in colorectal, breast, and ovarian cancers. Recently, some molecular hallmarks (e.g., TP53, KRAS, BRAF, RAD51C/D or PTEN mutations) of ovarian carcinomas were identified. The manuscript overviews the role of DNA repair machinery in ovarian cancer, its risk, prognosis, and therapy outcome. We have attempted to expose molecular hallmarks of ovarian cancer with a focus on DNA repair system and scrutinized genetic, epigenetic, functional, and protein alterations in individual DNA repair pathways (homologous recombination, non-homologous end-joining, DNA mismatch repair, base- and nucleotide-excision repair, and direct repair). We suggest that lack of knowledge particularly in non-homologous end joining repair pathway and the interplay between DNA repair pathways needs to be confronted. The most important genes of the DNA repair system are emphasized and their targeting in ovarian cancer will deserve further attention. The function of those genes, as well as the functional status of the entire DNA repair pathways, should be investigated in detail in the near future.

Abstract
The utility of the expression lack of DNA mismatch-repair (MMR) proteins in the detection of Lynch syndrome in endometrial hyperplasia as precursor lesion of endometrial carcinoma has not been well-established. The study investigated the immunoexpression pattern of MMR proteins in endometrial hyperplasia from Tunisian patients. We carried out a retrospective study of 60 endometrial hyperplasias diagnosed among Tunisian patients. Expression of MLH1, MSH2, MSH6, and PMS2 proteins was performed by immunohistochemistry on whole-slide sections of archival tissues. Analysis of MLH1 promoter methylation and microsatellite alterations was conducted in appropriate cases. Microsatellite instability screening was assessed using the Bethesda panel, including BAT25, BAT26, D17S250, D2S123, and D5S346 markers. Expression of MMR proteins was observed in all hyperplasias without atypia as well as in 27 out of 29 atypical hyperplasias. Only two atypical hyperplasias exhibited expression loss of MMR proteins. A single case revealed MSH6 expression lack. Expression loss of MLH1 and PMS2 was identified in another atypical hyperplasia and was associated with hypermethylation of MLH1 promoter. This patient had no familial history of endometrial cancer at the diagnostic time. The two deficient MMR cases showed microsatellite stable pattern. In conclusion, only two endometrial hyperplasias displayed an altered pattern of MMR expression. Our results suggest the limited utility of the immunohistochemical analysis of MMR protein in the early detection of Lynch syndrome in Tunisian patients diagnosed with endometrial hyperplasias. Multicenter studies with larger sample size are needed to more explore these findings.

Molecular profiling identifies synchronous endometrial and ovarian cancers as metastatic endometrial cancer with favorable clinical outcome. Int J Cancer 2020; 147:478-489. [PMID: 32022266 PMCID: PMC7317735 DOI: 10.1002/ijc.32907] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 01/17/2020] [Accepted: 01/22/2020] [Indexed: 01/14/2023]
Abstract
Synchronous primary endometrial and ovarian cancers (SEOs) represent 10% of all endometrial and ovarian cancers and are assumed to develop as independent entities. We investigated the clonal relationship between endometrial and ovarian carcinomas in a large cohort classified as SEOs or metastatic disease (MD). The molecular profiles were compared to The Cancer Genome Atlas (TCGA) data to explore primary origin. Subsequently, the molecular profiles were correlated with clinical outcome. To this extent, a retrospective multicenter study was performed comparing patients with SEOs (n = 50), endometrial cancer with synchronous ovarian metastasis (n = 19) and ovarian cancer with synchronous endometrial metastasis (n = 20). Targeted next‐generation sequencing was used, and a clonality index was calculated. Subsequently, cases were classified as POLE mutated, mismatch repair deficient (MMR‐D), TP53‐wild‐type or TP53‐mutated. In 92% of SEOs (46/50), the endometrial and concurrent ovarian carcinoma shared at least one somatic mutation, with a clonality index above 0.95, supporting a clonal origin. The SEO molecular profiles showed striking similarities with the TCGA endometrial carcinoma set. SEOs behaved distinctly different from metastatic disease, with a superior outcome compared to endometrial MD cases (p < 0.001) and ovarian MD cases (p < 0.001). Classification according to the TCGA identified four groups with different clinical outcomes. TP53 mutations and extra‐utero‐ovarian disease were independent predictors for poor clinical outcome. Concluding, SEOs were clonally related in an overwhelming majority of cases and showed a favorable prognosis. Their molecular profile implied a primary endometrial origin. TP53 mutation and extra‐utero‐ovarian disease were independent predictors for outcome, and may impact adjuvant systemic treatment planning. What's new? When primary endometrial and ovarian tumors are found simultaneously in the same patient, it has been assumed that they are separate cancers that developed independently. However, in this study, the authors found that these tumors share a clonal origin 92% of the time. They also found that these “synchronous” cancers tend to have a favorable prognosis, with far better outcomes than metastatic disease. Some subgroups, including TP53 mutations and extra‐utero‐ovarian disease, were independent predictors for poor clinical outcome, which may impact adjuvant treatment planning.

Abstract
Patients with Lynch syndrome have up to a 24% risk of developing ovarian carcinoma, but universal mismatch repair (MMR) protein testing of ovarian carcinomas is not standard practice in most institutions. We reviewed 104 unselected ovarian endometrioid carcinomas (OEC) for various clinicopathologic features to determine if any are predictive of MMR loss. Immunohistochemistry for all 4 MMR proteins was performed followed by MLH1 promoter methylation analysis when indicated. Overall, patients had a mean age of 55 years and tumors averaged 12 cm. Most (72%) patients had stage I tumors, 63% were grade 1, and 30% had a synchronous stage IA endometrial endometrioid carcinoma. Peritumoral lymphocytes and intratumoral stromal inflammation were rare, but tumor-infiltrating lymphocytes averaged 47/10 high-power fields. Endometriosis was noted in 71%, adenofibromatous background in 14%, and both in 14% of tumors. Metaplastic changes were common and included squamous metaplasia (63%), clear cell change (32%), mucinous differentiation (24%), and sex cord-like elements (13%). When follow-up was available (n=99), 78% of patients were alive and well, 12% died from disease, 6% died from other causes, and 4% were alive with disease. Unmethylated, MMR-deficient OECs were identified in 7% of the cohort and included MSH2/MSH6 (n=4), MSH6 (n=2), and PMS2 (n=1). All these tumors were stage I, 71% grade 1, and 57% had a synchronous endometrial endometrioid carcinoma. Among patients in this group with follow-up (n=5), all were alive without evidence of disease (mean 150 mo). Given that no clinicopathologic features were associated with MMR deficiency on univariate analysis, this study highlights the importance of universal MMR screening in OECs.

Abstract
Introduction Little is known about the prevalence and prognosis of synchronous endometrial and ovarian carcinomas. This report explores the survival outcomes of synchronous stage IA endometrioid endometrial and stage IA ovarian carcinomas in a retrospective cohort study. Methods All cases of pathological confirmed synchronous stage IA endometrial endometrioid and ovarian carcinomas from June 1, 2010, to June 1, 2017, in a teaching hospital were reviewed. Patients were followed up to February 1, 2019. Survival outcomes were compared between patients with and without synchronous carcinomas. Results In total, 841 cases with confirmed FIGO stage IA endometrioid endometrial carcinomas were included in the study; 33 patients (3.9%) had synchronous stage IA ovarian carcinomas, including 27 (81.8%) and 6 (18.2%) cases of endometrioid and mixed endometrioid/clear cell subtypes, respectively. After a median follow-up time of 56.8 months, 829 patients (97.9%) had definitive survival outcomes. Synchronous ovarian carcinomas had no impact on disease-free, overall or cancer-specific overall survival in univariate and multivariate analyses. Conclusion In these patients with stage IA endometrioid endometrial carcinoma, the genuine incidence of synchronous stage IA ovarian carcinoma was very low, and synchronous carcinoma had no significant effects on survival outcomes.

Abstract
In the era of advanced cancer genomics, our recognition of hereditary cancer mutations continues to increase. Two of these conditions, which carry an increased risk of female cancers including endometrial, ovarian, breast, are hereditary breast and ovarian cancer syndrome and Lynch syndrome. Risk-reducing surgery, such as mastectomy, salpingo-oophorectomy, and hysterectomy may decrease cancer risk for mutation carriers. Background, indications, techniques, and consequences of these surgical procedures are reviewed.

Abstract
AT-rich interaction domain 1A gene (ARID1A) encodes for a subunit of the switch/sucrose non-fermentable (SWI/SNF) complex, a chromatin remodeling complex, and it has been implicated in the pathogenesis of various cancer types. In this review, we discuss how ARID1A is linked to endometrial cancer and what molecular pathways are affected by mutation or inhibition of ARID1A. We also discuss the potential use of ARID1A not only as a prognostic biomarker, but also as a target for therapeutic interventions.

Abstract
Abstract
Objectives
Kidney cancer is a highly lethal cancer, of which the most common type is renal cell carcinoma (RCC). The targeted drugs used in treating RCC clinically have a lot of side effects. Therefore, it is urgent to find out effective agents with little toxic effects.
Methods
The antiproliferation effect of chlorogenic acid (CA) was performed using the CCK-8 assay. Then, we adopted colony formation assay, Annexin V/PI staining assay and JC-1 mitochondrial membrane potential assay to explore the mechanism of anticancer effect of CA. We also conducted qPCR and Western blot to determine the pathway involved.
Key findings
We identified that CA selectively suppressed proliferation of human RCC cell line A498 but not the human embryonic kidney cell HEK293. Mechanistic studies showed that CA significantly induced apoptosis, as indicated by activation of caspase protein and increased ratio of pro-apoptotic protein Bax to anti-apoptotic protein Bcl-2 (P < 0.05). Furthermore, we found that PI3K/Akt/mTOR signalling pathway is involved in the inhibitory effect of CA on A498 cells. Activation of this pathway increased proliferation and decreased apoptosis of A498 cells, exhibiting antagonism function against CA.
Conclusion
Our research firstly reports the efficacy of CA against RCC cells and elucidates the underlying molecular mechanisms. These findings indicate that CA is a potential agent for treating RCC.
