Abstract
Bilateral oophorectomy is one method of hormone suppression for premenopausal patients with hormone receptor-positive breast cancer. Such specimens could, in theory, harbor occult early ovarian cancer and/or metastatic breast cancer but guidelines for tissue sampling for pathologic examination remain to be addressed. Therefore, we evaluated oophorectomy specimens from 166 patients who underwent ovarian ablation for hormone receptor-positive breast cancer. Results of germline genetic testing were documented by the surgeon in only 31.3% of the pathology specimen requisition forms, whereas that information was available for 81.3% of patients elsewhere in the electronic medical records. All but 5.2% tested negative for a hereditary ovarian cancer gene pathogenic variant before oophorectomy. Complete tissue sampling was performed in 77.1% of the cases and representative sampling in the remainder. No cases of ovarian cancer were observed. Ovarian metastasis of breast cancer was identified in 9.6% of patients, all of whom were already known to have advanced-stage disease. The number of tissue cassettes per ovary required for complete tissue submission was on average three times higher than that for representative tissue sampling (P < 0.01) and ranged up to 20 cassettes per ovary when multiple follicle cysts were present. We propose that guidelines for tissue sampling in this context be defined by a combination of hereditary risk and macroscopic examination; representative sampling is reasonable for macroscopically normal ovaries in hormone receptor-positive breast cancer patients whose germline genetic testing is negative. Positive genetic test results merit complete tissue submission even if macroscopically normal. This strategy balances the goals of early ovarian cancer detection and optimal resource utilization. However, it depends on clear documentation of genetic test results. Our study demonstrates that many opportunities remain to close gaps in the communication of genetic test results by clinicians submitting oophorectomy specimens for pathologic evaluation.

Abstract
Pathological examination of surgical specimens and compilation of a surgical pathology report comprises a series of events which includes macroscopic examination and tissue sampling, either complete or selected. This step is critical but often overlooked in the literature and not given the attention it deserves. In this review, we discuss the macroscopic examination and grossing of gynaecological pathology specimens, with reference to national and international protocols. We provide guidance as to the degree of sampling necessary in different scenarios and stress that a common-sense approach is necessary with flexibility in the degree of sampling depending on a variety of factors.

Abstract
CONTEXT.— Clinical management of endometrial carcinoma largely depends on the morphologic parameters ascertained based on the pathologic evaluation of surgical resection specimens. However, there are numerous controversial and nonstandardized aspects of both the macroscopic and microscopic assessment of surgical specimens, including grossing, adequate sampling, diagnosis, staging, reporting, and ancillary testing. OBJECTIVE.— To provide a comprehensive practical review of standardized grossing, key morphologic findings for reporting and staging, and diagnostic and prognostic use of ancillary testing in endometrial carcinomas. DATA SOURCES.— The existing literature, recommendations of the International Society of Gynecological Pathologists, and specialty consensus guidelines. CONCLUSIONS.— This review article summarizes important aspects of the grossing and sampling of surgical resection specimens for microscopic examination, key morphologic parameters that are required for reporting and staging, and morphologic features and immunoprofiles helpful in the differential diagnosis of low-grade and high-grade endometrial carcinomas, as well as the current status of the molecular classification of endometrial carcinoma and human epidermal growth factor receptor 2 testing in serous carcinoma. The information presented herein can be helpful in overcoming diagnostic challenges and issues related to the pathology reporting of endometrial carcinoma to practicing anatomic pathologists.

Abstract
Endometrial carcinoma is the most common extraintestinal cancer in Lynch syndrome (LS). Recent studies have demonstrated mismatch repair (MMR) deficiency can be detected in benign endometrial glands in LS. We performed MMR immunohistochemistry in benign endometrium from endometrial biopsies and curettings (EMCs) from a study group of 34 confirmed LS patients and a control group of 38 patients without LS who subsequently developed sporadic MLH1-deficient or MMR-proficient endometrial carcinoma. MMR-deficient benign glands were only identified in patients with LS (19/34, 56%) and were not identified in any control group patient (0/38, 0%) ( P < 0.001). MMR-deficient benign glands were identified as large, contiguous groups in 18 of 19 cases (95%). MMR-deficient benign glands were identified in patients with germline pathogenic variants in MLH1 (6/8, 75%), MSH6 (7/10, 70%), and MSH2 (6/11, 55%) but not in patients with variants in PMS2 (0/4). MMR-deficient benign glands were seen in all EMC samples (100%) but in only 46% of endometrial biopsy samples ( P =0.02). Patients with MMR-deficient benign glands were significantly more likely to have endometrial carcinoma (53%) compared with LS patients with only MMR-proficient glands (13%) ( P =0.03). In conclusion, we demonstrated that MMR-deficient benign endometrial glands are frequently identified in EMB/EMC in women with LS and are a specific marker for LS. Women with LS with MMR-deficient benign glands were more likely to have endometrial carcinoma suggesting that MMR-deficient benign glands may be a biomarker of increased risk of endometrial carcinoma development in LS.

Patterns of care and outcomes of risk reducing surgery in women with pathogenic variants in non-BRCA and Lynch syndrome ovarian cancer susceptibility genes. Gynecol Oncol 2023; 173:1-7.

Abstract
OBJECTIVES Guidelines recommend risk-reducing bilateral salpingo-oophorectomy (RRSO) for women with pathogenic variants of non-BRCA and Lynch syndrome-associated ovarian cancer susceptibility genes. Optimal timing and findings at the time of RRSO for these women remains unclear. We sought to characterize practice patterns and frequency of occult gynecologic cancers for these women at our two institutions. METHODS Women with germline ovarian cancer susceptibility gene pathogenic variants who underwent RRSO between 1/2000-9/2019 were reviewed in an IRB-approved study. All patients were asymptomatic with no suspicion for malignancy at time of RRSO. Clinico-pathologic characteristics were extracted from the medical records. RESULTS 26 Non-BRCA (9 BRIP1, 9 RAD51C, and 8 RAD51D) and 75 Lynch (36 MLH1, 18 MSH2, 21 MSH6) pathogenic variants carriers were identified. Median age at time of RRSO was 47. There were no occurrences of occult ovarian or fallopian tube cancer in either group. Two patients (3%) in the Lynch group had occult endometrial cancer. Median follow up was 18 and 35 months for non-BRCA and Lynch patients, respectively. No patient developed primary peritoneal cancer upon follow up. Post-surgical complications occurred in 9/101 (9%) of patients. Hormone replacement therapy (HRT) was rarely used despite reported post-menopausal symptoms in 6/25 (23%) and 7/75 (37%) patients, respectively. CONCLUSIONS No occult ovarian or tubal cancers were observed in either group. No recurrent or primary gynecologic-related cancers occurred upon follow-up. Despite frequent menopausal symptoms, HRT use was rare. Both groups experienced surgical complications when hysterectomy and/or concurrent colon surgery was performed suggesting concurrent surgeries should only be performed when indicated.

Abstract
We report a rare case of primary nodal, poorly differentiated endometrioid carcinoma associated with Lynch syndrome. A 29-year-old female patient was referred by her general gynecologist for further imaging with suspected right-sided ovarian endometrioid cyst. Ultrasound examination by an expert gynecological sonographer at tertiary center revealed unremarkable findings in the abdomen and pelvis apart from three iliac lymph nodes showing signs of malignant infiltration in the right obturator fossa and two lesions in the 4b segment of the liver. During the same appointment ultrasound guided tru-cut biopsy was performed to differentiate hematological malignancy from carcinomatous lymph node infiltration. Based on the histological findings of endometrioid carcinoma from lymph node biopsy, primary debulking surgery including hysterectomy and salpingo-oophorectomy was performed. Endometrioid carcinoma was confirmed only in the three lymph nodes suspected on the expert scan and primary nodal origin of endometroid carcinoma developed from ectopic Müllerian tissue was considered. As a part of the pathological examination immunohistochemistry analysis for mismatch repair protein (MMR) expression was done. The findings of deficient mismatch repair proteins (dMMR) led to additional genetic testing, which revealed deletion of the entire EPCAM gene up to exon 1-8 of the MSH2 gene. This was unexpected considering her insignificant family history of cancer. We discuss the diagnostic work-up for patients presenting with metastatic lymph node infiltration by cancer of unknown primary and possible reasons for malignant lymph node transformation associated with Lynch syndrome.

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
Objective Lynch syndrome is a hereditary cancer syndrome caused by mismatch repair gene mutations, and female carriers are at an increased risk of endometrial and ovarian cancer. The best approach to screening is not yet clear and practice varies across countries and centers. We aimed to provide evidence to inform the best approach to screening and risk reduction. Methods A systematic search of the literature was conducted (Medline, Embase, PubMed). Studies evaluating the following were included: women with Lynch syndrome (by mismatch repair mutation or Amsterdam II criteria), screening methods for endometrial and/or ovarian cancer, intervention included endometrial biopsy, transvaginal ultrasound, or serum cancer antigen 125 (CA-125), outcomes evaluated were number of cancers and/or endometrial hyperplasia. Results A total of 18 studies of Lynch syndrome carriers which screened for endometrial cancer using transvaginal ultrasound and/or hysteroscopy/endometrial biopsy revealed an incidence of 3.9% at the time of screening. Most (64.1%) endometrial cancers detected were from screening, with the balance detected in symptomatic women at the first screening visits, regular review, or between screening intervals. In mismatch repair carriers, the overall sensitivity of endometrial screening was 66.7%, and the number needed to screen ranged between 4 and 38 (median 7). The sensitivity of endometrial biopsy was 57.1% and the number needed to screen was 23–380 (median 78). The sensitivity of transvaginal ultrasound was 34.4% and the number needed to screen was 35–973 (median 170). Fourteen studies which screened for ovarian cancer using transvaginal ultrasound and/or CA-125 revealed an incidence of 1.3% at the time of screening and 42.9% of ovarian cancers were detected at asymptomatic screening. The sensitivity of ovarian screening was 54.6%, and the number needed to screen was 9–191 (median 23) in mismatch repair carriers. Thirteen studies reported 5.8% incident endometrial cancers and 0.5% ovarian cancers at time of risk reducing surgery. Conclusions There is limited evidence to support screening for endometrial and ovarian cancer in Lynch syndrome and data on mortality reduction are not available. Further prospective, randomized trials comparing targeted screening methods are needed. Risk reducing surgery remains the most reliable way to reduce endometrial and ovarian cancer risk in Lynch syndrome.

Abstract
AIMS The hallmark of Lynch syndrome (LS) is DNA mismatch repair protein (MMR) deficiency. Recently, MMR deficiency in non-neoplastic colonic crypts has been identified as a novel indicator of LS. We aimed to determine whether MMR-deficient non-neoplastic endometrial glands can distinguish patients with and without LS, and to compare the level of MMR deficiency in the normal endometrium and colon in LS patients. METHODS AND RESULTS We evaluated the immunohistochemical expression of MMR proteins in the normal endometrial mucosa from 64 patients, including 34 patients with confirmed LS (17 with endometrial cancer and 17 without cancer), 30 patients with endometrial cancer without LS (10 with tumours with MLH1 promoter hypermethylation and 20 with MMR-proficient tumours), and in the normal colonic mucosa from 30 LS patients. MMR-deficient non-neoplastic endometrial glands were identified in 47% of LS patients and in no patients without LS (P < 0.001). MMR-deficient non-neoplastic glands were more often identified in LS patients with endometrial cancer (65%) than in those without endometrial cancer (29%) (P = 0.04). In contrast to what was seen in the normal colon, MMR-deficient glands in the normal endometrium were seen as large, contiguous groups, ranging in number from two to 101 (87% versus 45%, P = 0.02). MMR-deficient glands were identified at a higher density in the endometrium than in the colon in LS patients (median number of MMR-deficient glands, 22 versus two, P = 0.02). CONCLUSIONS Our findings indicate that MMR-deficient non-neoplastic endometrial glands constitute an indicator of LS, and that MMR-deficient glands in the endometrium are present in a pattern of contiguous large groups.

Abstract
Lynch syndrome (LS) is associated with an increased risk for colorectal, endometrial, and ovarian carcinomas in women. Risk-reducing hysterectomy and bilateral salpingo-oophorectomy (RRHSO) has been shown to be a cost-effective form of management and prevention of gynecological malignancies in patients with LS. Studies of incidental gynecologic malignancies identified in RRHSO are limited. In addition, recommendations on optimal handling of this type of specimen have ranged from submitting for microscopic examination the entire endometrium, fallopian tubes and ovaries to submitting only routine representative sections of these organs. In this study, we present the clinicopathologic findings of 29 cases of LS patients that underwent risk-reducing gynecologic surgery at our institution over a period of 13 yr. Clinical-pathologic information was obtained from the patients' charts and pathology reports. Significant pathologic abnormalities were identified in 17% (5/29) of cases, all showing endometrial hyperplasia. Four of them with atypical and 1 without atypical. All of our cases with endometrial pathology had significant findings on preoperative endometrial sampling. To further study the recommendation of in toto submission of the endometrium, ovaries and fallopian tubes and the utility of preoperative endometrial sampling, we undertook a literature review of all the reported cases of incidental pathologic findings identified in RRHSO. The findings of our cohort and the literature reviewed support in toto submission of endometrium, and adnexal structures in the absence of gross lesions. In addition, our findings show a definite benefit for preoperative endometrial sampling as part of the workup for LS patients undergoing RRHSO.

Abstract
OBJECTIVES Atypical hyperplasia of the endometrium is a significant risk factor for uterine endometrioid carcinoma (EC) and an indication for hysterectomy. Standard sampling of these specimens includes evaluation of the entire endometrium to identify possible EC. We evaluated a method of selective sampling in an effort to balance resource utilization with diagnostic accuracy in the detection of EC. METHODS Histologic diagnoses based on selective sampling (exclusion of every other block of endometrium) were compared with the original diagnosis based on complete sampling. RESULTS Double-blinded review of these cases using selective sampling detected EC in 92% of hysterectomies, including all high-grade/high-stage carcinomas. Selective sampling had an 82% agreement with the original diagnoses, with most discordant diagnoses attributable to interobserver variability. Adjusting for interobserver variability increased diagnostic agreement between selective and complete sampling to 96%. CONCLUSIONS Selective sampling is a feasible method to save time and resources while maintaining diagnostic accuracy.

Abstract
AIMS Lynch syndrome (LS) is associated with an increased risk of developing endometrial carcinoma (EC) and ovarian carcinoma (OC). There is considerable variability in current practices and opinions related to screening of newly diagnosed patients with EC/OC for LS. An online survey was undertaken to explore the extent of these differences. METHODS AND RESULTS An online questionnaire was developed by a panel of experts and sent to all members of the British Association of Gynaecological Pathologists (BAGP) and the International Society of Gynecological Pathologists (ISGyP). Anonymised results were received and analysed. Thirty-six BAGP and 44 ISGyP members completed the survey. More than 90% of respondents were aware of the association of LS with both EC and OC, but 34% were not aware of specific guidelines for LS screening. Seventy-one per cent of respondents agreed that universal screening for LS should be carried out in all newly diagnosed EC cases, with immunohistochemistry (IHC) alone as the preferred approach. Only 36% of respondents currently performed IHC or microsatellite instability testing on all newly diagnosed EC cases, with most of the remaining respondents practising selective screening, based on clinical or pathological features or both. A significant minority of respondents (35%) believed that patient consent was required before performance of mismatch repair (MMR) protein IHC. Almost all respondents favoured the use of standardised terminology for reporting MMR protein staining results, and this is proposed herein. CONCLUSION There is wide support for universal LS screening in patients with EC, but this survey highlights areas of considerable variation in practice.

Abstract
Endometrial cancer is the most common gynecologic neoplasm in developed countries; however, updated universal guidelines are currently not available to handle specimens obtained during the surgical treatment of patients affected by this disease. This article presents recommendations on how to gross and submit sections for microscopic examination of hysterectomy specimens and other tissues removed during the surgical management of endometrial cancer such as salpingo-oophorectomy, omentectomy, and lymph node dissection—including sentinel lymph nodes. In addition, the intraoperative assessment of some of these specimens is addressed. These recommendations are based on a review of the literature, grossing manuals from various institutions, and a collaborative effort by a subgroup of the Endometrial Cancer Task Force of the International Society of Gynecological Pathologists. The aim of these recommendations is to standardize the processing of endometrial cancer specimens which is vital for adequate pathological reporting and will ultimately improve our understanding of this disease.

Abstract
BACKGROUND Lynch syndrome (LS) accounts for 5% of all endometrial cancer (EC) cases and 4% of all lifetime risk of developing colorectal cancer. While current guidelines recommend LS screening for all patients with newly diagnosed colorectal cancer, there is no such guideline for screening patients with EC. DISCUSSION This review addresses LS screening and discusses algorithms for testing patients in the setting of newly diagnosed EC. CONCLUSION The successful diagnosis of LS has important implications, including prevention of LS-associated cancers among relatives and immunotherapy recommendations for patients with advanced EC and loss of expression of mismatch repair immunohistochemistry and microsatellite instability positive following failure of traditional treatment.

Abstract
Recognising hereditary predisposition in a cancer patient has implications both for the patient and the patient's kindred. For the latter, cascade germline testing can reassure those not-at-risk family members while carriers can be enrolled in cancer screening and prevention programs that are medically effective and economically sustainable for health care systems. Furthermore, in many of these syndromes, ramifications of molecular phenotypes are increasing, and it is now emerging that, in addition, they convey prognostic and predictive information. Although cancer predisposition syndromes are rare, these molecular phenotypes also occur as somatic events in sporadic cancer settings. The information obtained from these molecular phenotypes, regardless of germline or somatic origin, is being incorporated into clinical management in view of their manifold significance. Thus, increasingly, bespoke management of cancer patients involves testing for both germline and somatic mutations in tumours. Lynch syndrome and BRCA-1 and BRCA-2-associated hereditary breast and ovarian cancer are hereditary cancer syndromes frequently involving the gynaecological tract but tumours associated with similar molecular alterations may also occur sporadically. Thus, the molecular phenotype of mismatch repair deficiency, microsatellite instability or hypermutator phenotype may be attributable to germline or somatic events. Similarly, homologous recombination deficiency or 'BRCAness' in ovarian cancers may be syndromic or sporadic. While hereditary syndromes are well recognised, the prognostic and predictive implications of these molecular phenotypes have only recently been elucidated and these aspects will finally ensure that molecular screening may become standard of care. Thus, nowadays pathologists are asked to designate the molecular phenotype of these cancers and then determine whether it is due to hereditary or sporadic causes.

Abstract
OBJECTIVES A proper examination of surgical specimens is fundamental in anatomic pathology (AP) education. However, the resources available to residents may not always be suitable for efficient skill acquisition. We propose a method to enhance AP education by introducing high-definition videos featuring methods for appropriate specimen handling, viewable on two-dimensional (2D) and stereoscopic three-dimensional (3D) platforms. METHODS A stereo camera system recorded the gross processing of commonly encountered specimens. Three edited videos, with instructional audio voiceovers, were experienced by nine junior residents in a crossover study to assess the effects of the exposure (2D vs 3D movie views) on self-reported physiologic symptoms. A questionnaire was used to analyze viewer acceptance. RESULTS All surveyed residents found the videos beneficial in preparation to examine a new specimen type. Viewer data suggest an improvement in specimen handling confidence and knowledge and enthusiasm toward 3D technology. None of the participants encountered significant motion sickness. CONCLUSIONS Our novel method provides the foundation to create a robust teaching library. AP is inherently a visual discipline, and by building on the strengths of traditional teaching methods, our dynamic approach allows viewers to appreciate the procedural actions involved in specimen processing.

Abstract
Adenocarcinomas exhibiting gastric differentiation represent a recently described and uncommon subtype of non-human papillomavirus (HPV)-related cervical adenocarcinoma. They comprise a spectrum from a well-differentiated variant (adenoma malignum/mucinous variant of minimal deviation adenocarcinoma) to a more poorly differentiated overtly malignant form, generally referred to as gastric-type adenocarcinoma. Rarely, such tumors have also been described as primary vaginal neoplasms. Gastric-type adenocarcinomas exhibit considerable morphologic overlap with adenocarcinomas originating outside the female genital tract, especially mucinous adenocarcinomas arising in the pancreas and biliary tract. Moreover, they often metastasize to unusual sites, such as the ovary and peritoneum/omentum, where they can be mistaken for metastatic adenocarcinomas from other, nongynecologic sites. There is little information regarding the immunophenotype of gastric-type adenocarcinomas, and knowledge of this is important to aid in the distinction from other adenocarcinomas. In this study, we undertook a detailed immunohistochemical analysis of a large series of cervical (n=45) and vaginal (n=2) gastric-type adenocarcinomas. Markers included were cytokeratin (CK)7, CK20, CDX2, carcinoembryonic antigen, CA125, CA19.9, p16, estrogen receptor, progesterone receptor, MUC6, PAX8, PAX2, p53, hepatocyte nuclear factor 1 beta, carbonic anhydrase IX, human epidermal receptor 2 (HER2), and mismatch repair (MMR) proteins. All markers were classified as negative, focal (<50% of tumor cells positive), or diffuse (≥50% tumor cells positive) except for p53 (classified as "wild-type" or "mutation-type"), HER2 (scored using the College of American Pathologists guidelines for gastric carcinomas), and MMR proteins (categorized as retained or lost). There was positive staining with CK7 (47/47-45 diffuse, 2 focal), MUC6 (17/21-6 diffuse, 11 focal), carcinoembryonic antigen (25/31-12 diffuse, 13 focal), carbonic anhydrase IX (20/24-8 diffuse, 12 focal), PAX8 (32/47-20 diffuse, 12 focal), CA125 (36/45-5 diffuse, 31 focal), CA19.9 (11/11-8 diffuse, 3 focal), hepatocyte nuclear factor 1 beta (13/14-12 diffuse, 1 focal), CDX2 (24/47-4 diffuse, 20 focal), CK20 (23/47-6 diffuse, 17 focal), and p16 (18/47-4 diffuse, 14 focal). Most cases were negative with estrogen receptor (29/31), progesterone receptor (10/11), PAX2 (18/19), and HER2 (25/26). p53 showed "wild-type" and "mutation-type" staining in 27 of 46 and 19 of 46 cases, respectively. MMR protein expression was retained in 19 of 20 cases with loss of MSH6 staining in 1 patient with Lynch syndrome. Molecular studies for HPV were undertaken in 2 tumors, which exhibited diffuse "block-type" immunoreactivity with p16, and both were negative. This is the first detailed immunohistochemical study of a large series of gastric-type adenocarcinomas of the lower female genital tract. Our results indicate immunophenotypic overlap with pancreaticobiliary adenocarcinomas but suggest that PAX8 immunoreactivity may be especially useful in distinguishing gastric-type adenocarcinomas from pancreaticobiliary and other nongynecologic adenocarcinomas, which are usually negative. Diffuse "block-type" p16 immunoreactivity in a cervical adenocarcinoma is not necessarily indicative of a high-risk HPV-associated tumor.

Abstract
A comprehensive pathological report is essential for optimal patient management, cancer staging and prognostication. In many countries, proforma reports are used but these vary in their content. The International Collaboration on Cancer Reporting (ICCR) is an alliance formed by the Royal College of Pathologists of Australasia, the Royal College of Pathologists of the United Kingdom, the College of American Pathologists, the Canadian Partnership Against Cancer and the European Society of Pathology, with the aim of developing an evidence-based reporting data set for each cancer site. This will reduce the global burden of cancer data set development and reduplication of effort by different international institutions that commission, publish and maintain standardised cancer reporting data sets. The resultant standardisation of cancer reporting will benefit not only those countries directly involved in the collaboration but also others not in a position to develop their own data sets. We describe the development of a cancer data set by the ICCR expert panel for the reporting of primary ovarian, fallopian tube and peritoneal carcinoma and present the 'required' and 'recommended' elements to be included in the report with an explanatory commentary. This data set encompasses the recent International Federation of Obstetricians and Gynaecologists staging system for these neoplasms and the updated World Health Organisation Classification of Tumours of the Female Reproductive Organs. The data set also addresses issues about site assignment of the primary tumour in high-grade serous carcinomas and proposes a scoring system for the assessment of tumour response to neoadjuvant chemotherapy. The widespread implementation of this data set will facilitate consistent and accurate data collection, comparison of epidemiological and pathological parameters between different populations, facilitate research and hopefully will result in improved patient management.

Abstract
In France, endometrial cancer is at the first rank of gynecological cancers for cancer incidence, before ovarian and cervical cancers. In fact, the number of incident cases has been estimated to 7275 for the year 2012; the number of death due to endometrial cancer to 2025. This cancer is hormone-dependent and endogenous (reproductive factors) or exogenous (oral combined contraceptives, hormone replacement therapy) causes of exposition to estrogens are the major environmental risk factors for both types of endometrial cancers: type I or well-differentiated endometrioid adenocarcinomas; and type II including all other histological types: papillary serous adenocarcinomas, clear cell adenocarcinomas and carcinosarcomas, also known as malignant mixed Mullerian tumor, MMMT. Obesity, diabetes mellitus and adjuvant treatment of breast cancer with tamoxifen are also associated with an increased risk of endometrial cancer. Genetic factors may also be implicated in the pathogenesis of endometrial cancer either as "minor genetic factors" (susceptibility factors), which remain largely unknown and are responsible for the increased observed risk in relatives of women affected with endometrial cancer; or as major genetic factors responsible for hereditary forms and namely for Lynch syndrome whose genetic transmission is of autosomic dominant type. The appropriate recognition of Lynch syndrome is of critical importance because affected patients and their relatives should benefit from specific care. The aims of this review is to describe major environmental and genetic risk factors for endometrial cancer with specific attention to most recent advances in this field and to describe recommendations for care of at-risk women.

Abstract
Lynch syndrome is the most common cause of hereditary colon cancer, and accounts for as much as 3% of all colon and endometrial cancers. The identification and management of individuals with Lynch syndrome have evolved over the past 20 years, yet the syndrome remains vastly underdiagnosed. It is important for clinicians to recognize individuals and families who are at risk in order to be able to manage them appropriately and reduce their morbidity and mortality from this condition. This review will touch on the history of Lynch syndrome, the current knowledge of genotype–phenotype correlations, the cancers associated with Lynch syndrome, and management of individuals who are gene carriers.
