Abstract
This review comprehensively explores the complex role of copper homeostasis in female reproductive system diseases. As an essential trace element, copper plays a crucial role in various biological functions. Its dysregulation is increasingly recognized as a pivotal factor in the pathogenesis of gynecological disorders. We investigate how copper impacts these diseases, focusing on aspects like oxidative stress, inflammatory responses, immune function, estrogen levels, and angiogenesis. The review highlights significant changes in copper levels in diseases such as cervical, ovarian, endometrial cancer, and endometriosis, underscoring their potential roles in disease mechanisms and therapeutic exploration. The recent discovery of 'cuproptosis,' a novel cell death mechanism induced by copper ions, offers a fresh molecular perspective in understanding these diseases. The review also examines genes associated with cuproptosis, particularly those related to drug resistance, suggesting new strategies to enhance traditional therapy effectiveness. Additionally, we critically evaluate current therapeutic approaches targeting copper homeostasis, including copper ionophores, chelators, and nanoparticles, emphasizing their emerging potential in gynecological disease treatment. This article aims to provide a comprehensive overview of copper's role in female reproductive health, setting the stage for future research to elucidate its mechanisms and develop targeted therapeutic strategies.

Abstract
Reproductive cancers, encompassing various malignancies like endometrial, ovarian, cervical cancer, and gestational trophoblastic neoplasia, pose a significant global health burden. Understanding their patterns is vital for effective prevention and management. Contraceptives show a protective effect against some of these cancers. This clinical guidance document aims to elucidate the disease burden of reproductive cancers and the evidence supporting contraceptive methods in prevention and management. Regional disparities in incidence and mortality highlight the urgent need for targeted interventions, particularly in low-resource settings. Healthcare providers must weigh individual risk profiles and medical eligibility criteria when discussing contraceptive options. Enhanced health literacy through direct patient education is essential for leveraging low-cost behavioral interventions to mitigate reproductive cancer risks.

Abstract
BACKGROUND Micronutrients are important components for the homeostasis of the human body. The studies available in the literature of the subject on their impact on the risk of population diseases, including malignant neoplasms, are ambiguous. In this paper, the relationship between Cu and Zn serum levels and the occurrence of endometrial cancer have been analyzed. METHODS 306 patients (153 test group and 153 control group) matched for age were analyzed for Cu and Zn levels. Microelements levels were determined for sera collected during the hospitalization of patients by means of an inductively coupled plasma mass spectrometry. In addition, the Cu/Zn ratio in the population included in the study was analyzed. Univariable and multivariable analyzes were used to examine the relationship between the factors under study and the incidence of endometrial cancer. RESULTS Lower levels of elements were observed in the study group compared with the control group (Cu: 959.39 μg/L vs. 1176.42 μg/L, p < 0.001; Zn: 707.05 μg/L vs. 901.67 μg/L, p < 0.001). A statistically significant relationship with the occurrence of endometrial cancer was observed for Cu and Zn. The patients with the lowest Cu level had a significantly higher occurrence of endometrial cancer compared with reference tertile (OR 8.54; p < 0.001). Similarly, compared with the reference tertile, the patients with the lowest Zn levels had a significantly greater incidence of endometrial cancer (OR 15.0; p < 0.001). CONCLUSION The results of the study suggest an association of endometrial cancer occurrence with lower Cu and Zn serum levels.

Abstract
PURPOSE To explore the risk factors of endometrial lesions in patients with abnormal uterine bleeding(AUB) and establish prediction models which can discriminate between different endometrial etiologies of AUB. MATERIAL AND METHODS We conducted this cross-sectional study in consecutive 778 women with AUB who received ultrasound examination and endometrial histopathological examination. Models were developed to distinguish between normal endometrium and (1) endometrial lesions, (2) endometrial polyps, (3) endometrial hyperplasia without atypia, (4) endometrial atypical hyperplasia and endometrial carcinoma. RESULTS 274 (35.2%) women had normal endometrium; 504 (64.8%) had endometrial lesions, including 337(43.3%) endometrial polyps, 139(17.9%) endometrial hyperplasia without atypia, 28(3.6%) endometrial atypical hyperplasia and endometrial carcinoma. Age (OR = 1.122, 95%CI 1.002-1.257, P < 0.001), ET (endometrial thickness, OR = 2.702, 95%CI 1.629-4.402, P < 0.001), and CA125(U/ml) (OR = 1.007, 95%CI 1.003-1.021, P < 0.001) are independent risk factors of endometrial lesions in women with AUB. BMI(OR = 1.109, 95%CI 1.067-1.433,P = 0.038), ET(OR = 20.741, 95%CI 16.136-98.842, P < 0.001), age(OR = 1.182, 95%CI1.031-1.433,P = 0.016)、CA125(U/ml) (OR = 1.690, 95%CI 1.506-1.929,P = 0.001), prevalence of hypertension(OR = 1.350, 95%CI 1.051-67.82, P = 0.014) and diabetes(OR = 1.108, 95%CI 1.008-20.194,P = 0.001) were independent risk factors for atypical hyperplasia and endometrial carcinoma in patients with AUB. The model we built could predict atypical hyperplasia and endometrial carcinoma with the sensitivity of 87.5%, specificity of 80.7% and the AUC of 0.921. CONCLUSION In women with AUB, the new-built model based on age, BMI, endometrial thickness, hypertension, diabetes and CA125 could discriminate reliable between atypical hyperplasia, endometrial carcinoma and normal women. The model may be useful for management of AUB.

Am J Obstet Gynecol 2023; 229:93-100.

Abstract
The intrauterine device is one of the most effective forms of contraception. Use of the intrauterine device has increased in the United States over the last 2 decades. Two formulations are commercially available in the United States: the levonorgestrel-releasing intrauterine device and the copper intrauterine device. The levonorgestrel intrauterine device releases progestin, causing endometrial suppression and cervical mucus thickening, whereas the primary mechanism of action of the copper intrauterine device is to create a local inflammatory response to prevent fertilization. Whereas the protective effects of combined hormonal contraception against ovarian and endometrial cancer, and of tubal sterilization against ovarian cancer are generally accepted, less is known about the effects of modern intrauterine devices on the development of gynecologic malignancies. The best evidence for a protective effect of intrauterine device use against cancer incidence pertains to levonorgestrel intrauterine devices and endometrial cancer, although studies suggest that both copper intrauterine devices and levonorgestrel intrauterine devices reduce endometrial cancer risk. This is supported by the proposed dual mechanisms of action including both endometrial suppression and a local inflammatory response. Studies on the relationship between intrauterine device use and ovarian cancer risk show conflicting results, although most data suggest reduced risk of ovarian cancer in intrauterine device users. The proposed biological mechanisms of ovarian cancer reduction (foreign-body inflammatory response, increased pH, antiestrogenic effect, ovulation suppression) vary by type of intrauterine device. Whereas it has been well established that use of copper intrauterine devices confers a lower risk of cervical intraepithelial neoplasms, the effect of levonorgestrel intrauterine device use on cervical cancer remains unclear. Older studies have linked its use to a higher incidence of cervical dysplasia, but more recent literature has found a decrease in cervical cancer with intrauterine device use. Various mechanisms of protection are postulated, including device-related inflammatory response in the endocervical canal and prostaglandin-mediated immunosurveillance. Overall, the available evidence suggests that both levonorgestrel intrauterine devices and copper intrauterine devices reduce gynecologic cancer risk. Whereas there is support for the reduction of endometrial cancer risk with hormonal and copper intrauterine device use, and reduction of cervical cancer risk with copper intrauterine device use, evidence in support of risk reduction with levonorgestrel intrauterine device use for cervical and ovarian cancers is less consistent.

Abstract
Today most adolescents have their first sexual experience at the age of 15-19. However, only 44% of girls and young women (15-24 years old) report about contraception at that moment. A decision on pregnancy in adolescence is a difficult choice and any scenario may cause serious medical and social problems. Complications after an artificial abortion have a negative impact on a woman's fertility. Diabetes mellitus type 1 and arterial hypertension accompanied with obesity within the metabolic syndrome are defined by the World Health Organization (WHO) as diseases, which increase risk of an unplanned pregnancy. The article consoders problems of interaction of a doctor and a teenage girl with endocrinopathy, when discussing her sexual health, the analysis of the literature reflecting the influence of contraception on the course of the underlying pathology is presented. The authors formed a list of drugs acceptable for use in diabetes and obesity based on assessment of risks and preferences from the use of different methods of fertility control. The work contains information about the procedure of starting contraception, the rules of future dynamic monitoring of the patient.

Abstract
Purpose We aim to determine the predictive value of endometrial thickness by transvaginal ultrasonography (TVS) in diagnosing endometrial pathology and to evaluate whether Doppler complements its diagnostic efficacy in perimenopausal women with abnormal uterine bleeding. Methods This cross-sectional observational study was conducted among 70 perimenopausal women with AUB who underwent TVS measurement of endometrial thickness (ET) and Doppler flow indices followed by endometrial sampling and histopathological examination (HPE). Results In HPE, 51 (73%) women had normal diagnosis while 19 (27%) women had neoplastic histology either benign or malignant. They were categorised into group I and group II, respectively. There was a significant difference in age (P=0.001) and incidence of obesity (P=0.01) between the two groups. The ETs measured in group I and group II were 7.89 ± 2.62 mm and 14.07 ± 3.96 mm, respectively, with significant difference (P < 0.001). A TVS-ET of 10.5 mm had the highest sensitivity and specificity of 89.5% and 86.3%, respectively, PPV of 70.68%, NPV of 95.68%, LR+ of 6.52, and LR- of 0.12. Doppler flow velocimetric study of endometrial and uterine vessels did not demonstrate a significant difference. Conclusions Women in perimenopause with AUB should be offered to undergo endometrial sampling for histopathological examination if TVS ET ≥10.5 mm. The coexisting risk factors especially higher age (>45 years) and obesity (BMI>30) significantly escalate the chances of developing endometrial pathology.

Statistical Meta-Analysis of Risk Factors for Endometrial Cancer and Development of a Risk Prediction Model Using an Artificial Neural Network Algorithm. Cancers (Basel) 2021; 13:cancers13153689. [PMID: 34359595 PMCID: PMC8345114 DOI: 10.3390/cancers13153689] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 07/05/2021] [Accepted: 07/09/2021] [Indexed: 11/16/2022] Open
Abstract
Simple Summary A robust and comprehensive meta-analysis, for the first time, identified definitely that BMI is by far the most influential risk factor in endometrial cancer. Risk factors were previously only studied individually and or in smaller meta-analysis studies which grouped some factors together. BMI was shown to be an important risk factor with other factors less so, but no rank order was established. This work also offers, for the first time, a neural network computer model to predict the overall increase or decreased risk of cancer for individual patients, which is 98.6% accurate. This prediction can be used as a tool to determine if a patient should be considered for testing and to predict diagnosis, as well as to suggest prevention measures to patients. Abstract Objectives: In this study we wished to determine the rank order of risk factors for endometrial cancer and calculate a pooled risk and percentage risk for each factor using a statistical meta-analysis approach. The next step was to design a neural network computer model to predict the overall increase or decreased risk of cancer for individual patients. This would help to determine whether this prediction could be used as a tool to decide if a patient should be considered for testing and to predict diagnosis, as well as to suggest prevention measures to patients. Design: A meta-analysis of existing data was carried out to calculate relative risk, followed by design and implementation of a risk prediction computational model based on a neural network algorithm. Setting: Meta-analysis data were collated from various settings from around the world. Primary data to test the model were collected from a hospital clinic setting. Participants: Data from 40 patients notes currently suspected of having endometrial cancer and undergoing investigations and treatment were collected to test the software with their cancer diagnosis not revealed to the software developers. Main outcome measures: The forest plots allowed an overall relative risk and percentage risk to be calculated from all the risk data gathered from the studies. A neural network computational model to determine percentage risk for individual patients was developed, implemented, and evaluated. Results: The results show that the greatest percentage increased risk was due to BMI being above 25, with the risk increasing as BMI increases. A BMI of 25 or over gave an increased risk of 2.01%, a BMI of 30 or over gave an increase of 5.24%, and a BMI of 40 or over led to an increase of 6.9%. PCOS was the second highest increased risk at 4.2%. Diabetes, which is incidentally also linked to an increased BMI, gave a significant increased risk along with null parity and noncontinuous HRT of 1.54%, 1.2%, and 0.56% respectively. Decreased risk due to contraception was greatest with IUD (intrauterine device) and IUPD (intrauterine progesterone device) at −1.34% compared to −0.9% with oral. Continuous HRT at −0.75% and parity at −0.9% also decreased the risk. Using open-source patient data to test our computational model to determine risk, our results showed that the model is 98.6% accurate with an algorithm sensitivity 75% on average. Conclusions: In this study, we successfully determined the rank order of risk factors for endometrial cancer and calculated a pooled risk and risk percentage for each factor using a statistical meta-analysis approach. Then, using a computer neural network model system, we were able to model the overall increase or decreased risk of cancer and predict the cancer diagnosis for particular patients to an accuracy of over 98%. The neural network model developed in this study was shown to be a potentially useful tool in determining the percentage risk and predicting the possibility of a given patient developing endometrial cancer. As such, it could be a useful tool for clinicians to use in conjunction with other biomarkers in determining which patients warrant further preventative interventions to avert progressing to endometrial cancer. This result would allow for a reduction in the number of unnecessary invasive tests on patients. The model may also be used to suggest interventions to decrease the risk for a particular patient. The sensitivity of the model limits it at this stage due to the small percentage of positive cases in the datasets; however, since this model utilizes a neural network machine learning algorithm, it can be further improved by providing the system with more and larger datasets to allow further refinement of the neural network.

Abstract
Background Endometrial cancer is the second most common cancer among female cancer survivors in the United States. Cardiovascular disease is the leading cause of death among endometrial cancer survivors. Studies that examine long-term cardiovascular outcomes among endometrial cancer survivors are critical. Methods Cohorts of 2648 endometrial cancer survivors diagnosed between 1997 and 2012 and 10 503 age-matched women from the general population were identified. Cardiovascular disease diagnoses were identified from electronic medical records and statewide ambulatory surgery and statewide inpatient data. Cox regression models were used to estimate hazard ratios (HRs) at one to five years, more than five to 10 years, and more than 10 years after cancer diagnosis. Results Between one and five years after diagnosis, increased cardiovascular risks among endometrial cancer survivors were observed for phlebitis, thrombophlebitis, and thromboembolism (HR = 2.07, 99% confidence interval [CI] = 1.57 to 2.72), pulmonary heart disease (HR = 1.74, 99% CI = 1.26 to 2.40), and atrial fibrillation (HR = 1.50, 99% CI = 1.07 to 2.11). At more than five to 10 years, some elevated risk persisted for cardiovascular diseases. Compared with patients who had surgery, patients who additionally had radiation therapy and/or chemotherapy were at increased risk for heart and circulatory system disorders between one and five years after cancer diagnosis. Older age and obesity were also risk factors for hypertension and heart disease among endometrial cancer survivors. Conclusions Endometrial cancer survivors are at higher risk for various adverse long-term cardiovascular outcomes compared with women from the general population. This study suggests that increased monitoring for cardiovascular diseases may be necessary for endometrial cancer patients for 10 years after cancer diagnosis.

Abstract
BACKGROUND Type-II endometrial cancer is an estrogen independent and one of the most lethal types of cancer having poor prognosis. Adipokines play a crucial role in the triggering Type-II EMC. In addition, adipokines modulators, therefore, may have beneficial effects in the treatment of Type-II endometrial cancer, which was clinically evidenced. AREAS COVERED This review presents the role of various adipokines involved and also the suitable modulators to treat Type-II endometrial cancer. CONCLUSION In the present review, we try to discuss the role of individual adipokines in the pathogenesis of Type-II endometrial cancer, and also the possible beneficial effects of adipokines modulator in the treatment of Type-II endometrial cancer.

Abstract
The French College of Obstetrics and Gynecology (CNGOF) has released its first comprehensive recommendations for clinical practices in contraception, to provide physicians with an updated synthesis of the available data as a basis for their practice. The organizing committee and the working group adopted the objective methodological principles defined by the French Authority for Health (HAS) and selected 12 themes relevant to medical professionals' clinical practices concerning contraception. The available literature was screened through December 2017 and served as the basis of 12 texts, reviewed by experts and physicians from public and private practices, with experience in this field. These texts enabled us to develop evidence based, graded recommendations. Male and female sterilization, as well as the use of hormonal treatments not authorized for contraception ("off-label") were excluded from the scope of our review. Specific practical recommendations are provided for the management of contraception prescription, patient information concerning effectiveness, risks, and benefits of the different methods, patient follow-up, intrauterine contraception, emergency contraception, local and natural methods, contraception in teenagers, in women after 40, for women at high thromboembolism or cardiovascular risk, and for those at of primary cancer or relapse. The short- and mid-term future of contraception depends mainly on improving the use of currently available methods. This includes reinforced information for users and increased access to contraception for women, regardless of their social and clinical contexts. The objective of these guidelines is to aid in enabling this improvement.

Injectable Vaginal Hydrogels as a Multi-Drug Carrier for Contraception. APPLIED SCIENCES-BASEL 2019. [DOI: 10.3390/app9081638] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/18/2022]
Abstract
Injectable intravaginal hydrogels could deliver drugs systemically without hepatic first pass effect. This paper focuses on the contraceptive function of an injectable temperature-sensitive four-arm star-shaped poly(D,L-lactic-co-glycolic acid)-b-methoxy poly(ethylene glycol) (4sPLGA-mPEG) block copolymer hydrogels as a carrier of three drugs. In vitro controlled release profiles were investigated via HPLC, and it showed that the cumulative release amounts of indomethacin (IMC), gestodene (GSD), and ethinyl estradiol (EE) from copolymer hydrogels could be regulated by adjusting the lactide/glycolide (LA/GA) mol ratio. In addition, in vitro release profiles of IMC, GSD, and EE well corresponded to Higuchi model. The acute toxicity of copolymer hydrogels loaded with different dosage contents multi-drug was evaluated in vivo. As to the high dosage group, the uterus was hydropic at day 1 and ulcerated at day 5, followed with intestinal adhesion. Regarding the middle dosage group, no festering of tissues was observed and, blood coagulum existed in the uterus at different days. For low dosage group, no significant tissue necrosis was found. Finally, the antifertility experiments confirmed that hydrogels loaded with the multi-drug had an excellent contraceptive effect. The above results indicated that injectable copolymer hydrogel as a multi-drug carrier was promising as a novel contraception method.

Abstract
BACKGROUND The Surveillance, Epidemiology, and End Result (SEER) database shows a variable increase in endometrial cancer incidence over time. The objective of this review was to examine published endometrial cancer rates and potential etiologies. METHODS Endometrial cancer incidence was obtained from the SEER Program database from 1975 through 2014, and a test for trend in incidence was calculated. Changes in risk factors thought to be associated with endometrial cancer, including age, obesity, diabetes, diet and exercise, reproductive factors, and medications (hormone therapy [HT] including Food and Drug Administration [FDA]-approved and non-FDA-approved [compounded] estrogens and progestogens, tamoxifen, and hormonal contraceptives) were found through PubMed searches. Temporal trends of risk factors were compared with endometrial cancer trends from SEER. RESULTS Although endometrial cancer rates were constant from 1992 to 2002 (women 50-74 years of age), they increased 2.5% annually with a 10% increase from 2006 to 2012 (trend test 0.82). Use of approved prescription estrogen-progestogen combination products decreased after the publication of the Women's Health Initiative (WHI) data, whereas other risk factors either remained constant or decreased during the same time; however, compounded bioidentical HT (CBHT) use increased coincident with the endometrial cancer increase. CONCLUSION Endometrial cancer rate increases after the first publication of WHI data in 2002 may be associated with the decreased use of approved estrogen-progestogen therapy, the increase in CBHT use, and the prevalence of obesity and diabetes; potential relationships require further evaluation.

The French Health Authority (HAS) methodology was used. Twelve practical issues were selected by the organizing committee and the task force members. The available literature was screened until December 2017, and allowed the release of evidence-based, graded recommendations. This synthesis is issued from 12 developed texts, previously reviewed by experts and physicians from public and private practices, with an experience in the contraceptive field. Male and female sterilization, as well as the use of hormonal treatments without contraceptive label were excluded from the field of this analysis. Specific practical recommendations on the management of contraception prescription, patient information including efficacy, risks, and benefits of the different contraception methods, follow up, intrauterine contraception, emergency contraception, local and natural methods, contraception in teenagers and after 40, contraception in vascular high-risk situations, and in case of cancer risk are provided.

Abstract
Hormonal and intrauterine contraceptive methods provide women with highly efficient protection against undesired pregnancy. Additional non-contraceptive effects are now well documented. Combined hormonal contraceptives use, either through the oral transdermal and vaginal route, allow a reduction in menorrhagia, dysmenorrhea, functional ovarian cysts, benign breast and uterine disease, endometriosis-related pain and recurrence. A reduction in ovarian cancer risks, including in women with BRCA syndrome, endometrial and colon cancer is documented. This effect is prolonged for years after contraception discontinuation. Non-contraceptive benefits of progestin-only contraceptives are less documented. Use of the levonorgestrel IUD is associated with a reduction in menorrhagia, dysmenorrhea including in case of endometriosis. Copper IUD use is associated with a decrease in cervix and endometrial cancer risk.

Abstract
Long-acting reversible contraception—intrauterine devices and contraceptive implants—offers the highest protection against unintended pregnancies. In addition, the use of reversible hormonal contraception has added health benefits for women in both the short and the long term. This review will give an overview of the benefits of reversible contraception as well as an evidence-based recommendation on how it should be used to benefit women the most.

Abstract
The use of effective and reversible contraception is characterized by many non-contraceptive benefits distinct from its ability to prevent pregnancy. Notably, the use of hormonal and non-hormonal birth control methods is known to impact the risk for developing certain female genital cancers as well as breast and colon cancers. We present here the current understanding of the role of effective and reversible contraceptives in the prevention and development of female genital cancers along with breast and colon cancers. Despite ongoing but unsubstantiated concerns regarding the use of hormonal and intrauterine contraceptives for a variety of clinical outcomes including cancer, contraceptive use in high- and low-risk reproductive-aged women remains an important part of cancer risk reduction for many malignancies.

Abstract
Obesity is a significant risk factor for the development of endometrial hyperplasia and cancer. More conservative prevention and management strategies are attractive due to the increased surgical risk and complication rates associated with obesity. The Levonorgestrel-releasing intrauterine system (LNG-IUS, Mirena) has been shown to reduce the risk of developing endometrial cancer. The recent joint Green Top Guideline on the Management of Endometrial Hyperplasia published by the Royal College of Obstetricians and Gynaecologists (RCOG) with the British Society for Gynaecological Endoscopy (BSGE) recommends the LNG-IUS for the medical management of endometrial hyperplasia without atypia. This case study reports on the development of endometrioid adenocarcinoma despite the presence of an LNG-IUS following a negative hysteroscopy in a 56-year-old woman with morbid obesity. This report highlights the need for patients and clinicians to remain vigilant to the early warning signs of developing endometrial cancer, especially in those at an increased risk secondary to obesity.

Abstract
Endometrial carcinoma is the most common gynecologic cancer in developed nations, and the annual incidence is projected to increase, secondary to the high prevalence of obesity, a strong endometrial carcinoma risk factor. Although endometrial carcinomas are etiologically, biologically, and clinically diverse, hormonal and metabolic mechanisms are particularly strongly implicated in the pathogenesis of endometrioid carcinoma, the numerically predominant subtype. The centrality of hormonal and metabolic disturbances in the pathogenesis of endometrial carcinoma, combined with its slow development from well-characterized precursors in most cases, offers a substantial opportunity to reduce endometrial carcinoma mortality through early detection, lifestyle modification, and chemoprevention. In this chapter, we review the epidemiology of endometrial carcinoma, emphasizing theories that link risk factors for these tumors to hormonal and metabolic mechanisms. Future translational research opportunities related to prevention are discussed.

Abstract
OBJECTIVES The aim of this study is to explore incidence and incidence-based mortality trends for endometrial cancer in the USA and project future incident cases, accounting for differences by race and histological subtype. METHODS Data on age-adjusted and age-specific incidence and mortality rates of endometrial cancer were obtained from the Surveillance, Epidemiology, and End Results 18 registries. Trends in rates were analyzed using Joinpoint regression, and average annual percent change (AAPC) in recent years (2006-2011) was computed for histological subtypes by race. Age, histological, and race-specific rates were applied to US Census Bureau population census estimates to project new cases from 2015 to 2040, accounting for observed AAPC trends, which were progressively attenuated for the future years. RESULTS The annual number of cases is projected to increase substantially from 2015 to 2040 across all racial groups. Considerable variation in incidence and mortality trends was observed both between and within racial groups when considering histology. CONCLUSIONS As the US population undergoes demographic changes, incidence of endometrial cancer is projected to rise. The increase will occur in all racial groups, but larger increases will be seen in aggressive histology subtypes that disproportionately affect black women.

Abstract
OBJECTIVE To systematically review the literature on the association between obesity and endometrial hyperplasia or cancer in premenopausal women. DATA SOURCES We searched the bibliographic databases MEDLINE, EMBASE, PubMed, and CINAHL (inception to May 5, 2015), and checked reference lists of included studies and systematic reviews. STUDY ELIGIBILITY CRITERIA Studies of more than 50 women with endometrial pathology diagnosed during premenopause that reported on obesity as a risk factor were eligible. STUDY APPRAISAL AND SYNTHESIS METHODS Study identification and data extraction were independently performed by 2 authors. Where possible, data were pooled in a generic inverse variance forest plot. Heterogeneity was reported using the I(2) statistic. RESULTS Nine case-control studies of moderate quality were included. Quantitative analysis of 5 studies showed a dose-response relationship of body mass index and increased risk of endometrial cancer. For studies of women with body mass index of ≥25, the pooled odds ratio was 3.85 (95% confidence interval 2.53-5.84); body mass index of ≥30 was 5.25 (4.00-6.90); and body mass index of ≥40 was 19.79 (11.18-35.03). CONCLUSION Body mass index is a consistent and leading risk factor for endometrial complex hyperplasia or cancer in premenopausal women. Body mass index should be considered when deciding to assess the endometrium in symptomatic premenopausal women.

Abstract
OBJECTIVE To provide guidelines for health care providers on the use of contraceptive methods to prevent pregnancy and on the promotion of healthy sexuality. OUTCOMES Overall efficacy of cited contraceptive methods, assessing reduction in pregnancy rate, safety, ease of use, and side effects; the effect of cited contraceptive methods on sexual health and general well-being; and the relative cost and availability of cited contraceptive methods in Canada. EVIDENCE Published literature was retrieved through searches of Medline and The Cochrane Database from January 1994 to January 2015 using appropriate controlled vocabulary (e.g., contraception, sexuality, sexual health) and key words (e.g., contraception, family planning, hormonal contraception, emergency contraception). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English from January 1994 to January 2015. Searches were updated on a regular basis in incorporated in the guideline to June 2015. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The quality of the evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). CHAPTER 7: INTRAUTERINE CONTRACEPTION: SUMMARY STATEMENTS 1. Intrauterine contraceptives are as effective as permanent contraception methods. (II-2) 2. The use of levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg by patients taking tamoxifen is not associated with recurrence of breast cancer. (I) 3. Intrauterine contraceptives have a number of noncontraceptive benefits. The levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg significantly decreases menstrual blood loss (I) and dysmenorrhea. (II-2) Both the copper intrauterine device and the LNG-IUS significantly decrease the risk of endometrial cancer. (II-2) 4. The risk of uterine perforation decreases with inserter experience but is higher in postpartum and breastfeeding women. (II-2) 5. The risk of pelvic inflammatory disease (PID) is increased slightly in the first month after intrauterine contraceptive (IUC) insertion, but the absolute risk is low. Exposure to sexually transmitted infections and not the IUC itself is responsible for PID occurring after the first month of use. (II-2) 6. Nulliparity is not associated with an increased risk of intrauterine contraceptive expulsion. (II-2) 7. Ectopic pregnancy with an intrauterine contraceptive (IUC) is rare, but when a pregnancy occurs with an IUC in situ, it is an ectopic pregnancy in 15% to 50% of the cases. (II-2) 8. In women who conceive with an intrauterine contraceptive (IUC) in place, early IUC removal improves outcomes but does not entirely eliminate risks. (II-2) 9. Intrauterine contraceptives do not increase the risk of infertility. (II-2) 10. Immediate insertion of an intrauterine contraceptive (10 minutes postplacental to 48 hours) postpartum or post-Caesarean section is associated with a higher continuation rate compared with insertion at 6 weeks postpartum. (I) 11. Immediate insertion of an intrauterine contraceptive (IUC; 10 minutes postplacental to 48 hours) postpartum or post-Caesarean section is associated with a higher risk of expulsion. (I) The benefit of inserting an IUC immediately postpartum or post-Caesarean section outweighs the disadvantages of increased risk of perforation and expulsion. (II-C) 12. Insertion of an intrauterine contraceptive in breastfeeding women is associated with a higher risk of uterine perforation in the first postpartum year. (II-2) 13. Immediate insertion of an intrauterine contraceptive (IUC) post-abortion significantly reduces the risk of repeat abortion (II-2) and increases IUC continuation rates at 6 months. (I) 14. Antibiotic prophylaxis for intrauterine contraceptive insertion does not significantly reduce postinsertion pelvic infection. (I) RECOMMENDATIONS: 1. Health care professionals should be careful not to restrict access to intrauterine contraceptives (IUC) owing to theoretical or unproven risks. (III-A) Health care professionals should offer IUCs as a first-line method of contraception to both nulliparous and multiparous women. (II-2A) 2. In women seeking intrauterine contraception (IUC) and presenting with heavy menstrual bleeding and/or dysmenorrhea, health care professionals should consider the use of the levonorgestrel intrauterine system 52 mg over other IUCs. (I-A) 3. Patients with breast cancer taking tamoxifen may consider a levonorgestrel-releasing intrauterine system 52 mg after consultation with their oncologist. (I-A) 4. Women requesting a levonorgestrel-releasing intrauterine system or a copper-intrauterine device should be counseled regarding changes in bleeding patterns, sexually transmitted infection risk, and duration of use. (III-A) 5. A health care professional should be reasonably certain that the woman is not pregnant prior to inserting an intrauterine contraceptive at any time during the menstrual cycle. (III-A) 6. Health care providers should consider inserting an intrauterine contraceptive immediately after an induced abortion rather than waiting for an interval insertion. (I-B) 7. In women who conceive with an intrauterine contraceptive (IUC) in place, the diagnosis of ectopic pregnancy should be excluded as arly as possible. (II-2A) Once an ectopic pregnancy has been excluded, the IUC should be removed without an invasive procedure. The IUC may be removed at the time of a surgical termination. (II-2B) 8. In the case of pelvic inflammatory disease, it is not necessary to remove the intrauterine contraceptive unless there is no clinical improvement after 48 to 72 hours of appropriate antibiotic treatment. (II-2B) 9. Routine antibiotic prophylaxis for intrauterine contraceptive (IUC) insertion is not indicated. (I-B) Health care providers should perform sexually transmitted infection (STI) testing in women at high risk of STI at the time of IUC insertion. If the test is positive for chlamydia and/or gonorrhea, the woman should be appropriately treated postinsertion and the IUC can remain in situ. (II-2B) 10. Unscheduled bleeding in intrauterine contraception users, when persistent or associated with pelvic pain, should be investigated to rule out infection, pregnancy, gynecological pathology, expulsion or malposition. (III-A)

Abstract
A variety of contraception options are available in addition to traditional combined oral contraceptive pills. Newer long-acting reversible contraceptive (LARC) methods such as intrauterine devices and subcutaneous implants are preferred because they do not depend on patient compliance. They are highly effective and appropriate for most women. Female and male sterilization are other effective but they are irreversible and require counseling to minimize regret. The contraceptive injection, patch, and ring do not require daily administration, but their typical efficacy rates are lower than LARC methods and similar to those for combined oral contraceptive pills.

Abstract
OBJECTIVE To examine the association between premenopausal use of the levonorgestrel-releasing intrauterine system and cancer incidence in Finland with a special focus on endometrial adenocarcinoma. METHODS All Finnish women aged 30-49 years using a levonorgestrel-releasing intrauterine system for treatment of menorrhagia in 1994-2007 (n=93,843) were identified from the National Reimbursement Registry and linked to the Finnish Cancer Registry data. The incidence of cancers in levonorgestrel-releasing intrauterine system users was compared with that in the general population. RESULTS A total of 2,781 cancer cases were detected in levonorgestrel-releasing intrauterine system users during the follow-up of 855,324 women-years. The standardized incidence ratio (observed-to-expected ratio) for endometrial adenocarcinoma was 0.50 (95% confidence interval [CI] 0.35-0.70; 34 observed compared with 68 expected cases) after the first levonorgestrel-releasing intrauterine system purchase and 0.25 (95% CI 0.05-0.73; three observed compared with 12 expected cases) after two purchases. The standardized incidence ratio for ovarian cancer was 0.60 (95% CI 0.45-0.76; 59 observed compared with 99 expected cases), for pancreatic cancer 0.50 (95% CI 0.28-0.81; 15 observed compared with 30 expected cases), and for lung cancer 0.68 (95% CI 0.49-0.91; 43 observed compared with 63 expected cases). The standardized incidence ratio for breast cancer among all levonorgestrel-releasing intrauterine system users was 1.19 (95% CI 1.13-1.25; 1,542 observed compared with 1,292 expected cases). CONCLUSION The levonorgestrel-releasing intrauterine system may have a protective effect against endometrial malignant transformation. Using the levonorgestrel-releasing intrauterine system for treatment of menorrhagia during reproductive years was associated with a lower incidence of endometrial, ovarian, pancreatic, and lung cancers than expected. Levonorgestrel-releasing intrauterine system use was associated with a higher than expected incidence of breast cancer. LEVEL OF EVIDENCE II.

Abstract
Intrauterine devices (IUDs), long-acting and reversible contraceptives, induce a number of immunological and biochemical changes in the uterine environment that could affect endometrial cancer (EC) risk. We addressed this relationship through a pooled analysis of data collected in the Epidemiology of Endometrial Cancer Consortium. We combined individual-level data from 4 cohort and 14 case-control studies, in total 8,801 EC cases and 15,357 controls. Using multivariable logistic regression, we estimated pooled odds ratios (pooled-ORs) and 95% confidence intervals (CIs) for EC risk associated with ever use, type of device, ages at first and last use, duration of use and time since last use, stratified by study and adjusted for confounders. Ever use of IUDs was inversely related to EC risk (pooled-OR = 0.81, 95% CI = 0.74-0.90). Compared with never use, reduced risk of EC was observed for inert IUDs (pooled-OR = 0.69, 95% CI = 0.58-0.82), older age at first use (≥ 35 years pooled-OR = 0.53, 95% CI = 0.43-0.67), older age at last use (≥ 45 years pooled-OR = 0.60, 95% CI = 0.50-0.72), longer duration of use (≥ 10 years pooled-OR = 0.61, 95% CI = 0.52-0.71) and recent use (within 1 year of study entry pooled-OR = 0.39, 95% CI = 0.30-0.49). Future studies are needed to assess the respective roles of detection biases and biologic effects related to foreign body responses in the endometrium, heavier bleeding (and increased clearance of carcinogenic cells) and localized hormonal changes.

Abstract
Three intrauterine devices (IUDs), one copper and two containing the progestin levonorgestrel, are available for use in the United States. IUDs offer higher rates of contraceptive efficacy than nonlong-acting methods, and several studies have demonstrated higher satisfaction rates and continuation rates of any birth control method. This efficacy is not affected by age or parity. The safety of IUDs is well studied, and the risks of pelvic inflammatory disease, perforation, expulsion, and ectopic pregnancy are all of very low incidence. Noncontraceptive benefits include decreased menstrual blood loss, improved dysmenorrhea, improved pelvic pain associated with endometriosis, and protection of the endometrium from hyperplasia. The use of IUDs is accepted in patients with multiple medical problems who may have contraindications to other birth control methods. Yet despite well-published data, concerns and misperceptions still persist, especially among younger populations and nulliparous women. Medical governing bodies advocate for use of IUDs in these populations, as safety and efficacy is unchanged, and IUDs have been shown to decrease unintended pregnancies. Dispersion of accurate information among patients and practitioners is needed to further increase the acceptability and use of IUDs.

Abstract
Although the contemporary management of endometrial cancer is straightforward in many ways, novel data has emerged over the past decade that has altered the clinical standards of care while generating new controversies that will require further investigation. Fortunately most cases are diagnosed at early stages, but high-risk histologies and poorly differentiated tumors have high metastatic potential with a significantly worse prognosis. Initial management typically requires surgery, but the role and extent of lymphadenectomy are debated especially with well-differentiated tumors. With the changes in surgical staging, prognosis correlates more closely with stage, and the importance of cytology has been questioned and is under evaluation. The roles of radiation in intermediate-risk patients and chemotherapy in high-risk patients are emerging. The therapeutic index of brachytherapy needs to be considered, and the best sequencing of combined modalities needs to balance efficacy and toxicities. Additionally novel targeted therapies show promise, and further studies are needed to determine the appropriate use of these new agents. Management of endometrial cancer will continue to evolve as clinical trials continue to answer unsolved clinical questions.

Abstract
Differentiating ovarian tumors based on developmental pathway may further enhance our understanding of the disease. Traditionally, ovarian cancers were thought to arise from the ovarian surface epithelium; however, recent evidence suggests that some tumors originate in the fallopian tube. We classified cases in a population-based case-control study (New England Case-Control [NECC] Study) and two cohort studies (Nurses' Health Study [NHS]/Nurses' Health Study II [NHSII]) by tumor dominance, a proxy for tissue of origin. Dominant tumors (likely ovarian origin) are restricted to one ovary or are at least twice as large on one ovary compared to the other. Ovarian cancer risk factors were evaluated in relation to dominant and nondominant tumors (likely tubal origin) using polytomous logistic regression (NECC) or competing risks Cox models (NHS/NHSII). Results were combined using random-effects meta-analyses. Among 1,771 invasive epithelial ovarian cancer cases, we observed 1,089 tumors with a dominant mass and 682 with no dominant mass. Dominant tumors were more likely to be mucinous, endometrioid or clear cell, whereas nondominant tumors were more likely to be serous. Tubal ligation, two or more births, endometriosis and age were more strongly associated with dominant tumors (rate ratio [RR] = 0.60, 0.83, 1.58 and 1.37, respectively) than nondominant tumors (RR = 1.03, 0.93, 0.84 and 1.14, respectively; p-difference = 0.0001, 0.01, 0.0003 and 0.01, respectively). These data suggest that risk factors for tumors putatively arising from ovarian versus fallopian tube sites may differ; in particular, reproductive factors may be more important for ovarian-derived tumors. As this is the first study to evaluate ovarian cancer risk factors by tumor dominance, these results need to be validated by other studies.

Abstract
Increasing contraceptive use in developing countries has cut the number of maternal deaths by 40% over the past 20 years, merely by reducing the number of unintended pregnancies. By preventing high-risk pregnancies, especially in women of high parities, and those that would have ended in unsafe abortion, increased contraceptive use has reduced the maternal mortality ratio--the risk of maternal death per 100,000 livebirths--by about 26% in little more than a decade. A further 30% of maternal deaths could be avoided by fulfilment of unmet need for contraception. The benefits of modern contraceptives to women's health, including non-contraceptive benefits of specific methods, outweigh the risks. Contraception can also improve perinatal outcomes and child survival, mainly by lengthening interpregnancy intervals. In developing countries, the risk of prematurity and low birthweight doubles when conception occurs within 6 months of a previous birth, and children born within 2 years of an elder sibling are 60% more likely to die in infancy than are those born more than 2 years after their sibling.

Abstract
Since the 1959 revival of the IUD, non-hormonal devices have become the most widely used of all reversible contraceptives. Pregnancy rates of copper-releasing IUDs in current use range from approximately 0.5 to 1.5 per hundred continuing users in the first year, with somewhat lower annual pregnancy rates thereafter. Evidence-based research has been systematically conducted and translated into guidelines for eligibility criteria and problem management. Recent device research, beyond the T, Multiload and frameless devices has centred on improved designs such as U ,Y and Slimline shapes, or enhanced copper release, the latter through electrochemical effects or nanotechnology applications. Other IUD research foci concern devices that decrease bleeding and pain by releasing non-steroidal anti-inflammatory drugs. Yet other research lines indicate noncontraceptive benefits of copper intrauterine devices in protecting against endometrial cancer, and favourable risk-benefit analyses of IUD use by women at risk of or post HIV infection. IUD mechanisms of action and the relation of IUDs to pelvic infection and ectopic pregnancy are briefly reviewed. For our literature search we used Medline, Popline and Cochrane Library data bases, Google search, our personal files, and the references contained in articles in our files.

Abstract
Worldwide, obesity has become a major public health crisis. Overweight and obesity not only increase the risk of cardiovascular disease and type-2 diabetes mellitus but also are now known risk factors for a variety of cancer types. Among all cancers, increasing body mass index is associated most strongly with endometrial cancer incidence and death. The molecular mechanisms underlying how adipose tissue and obesity contribute to the pathogenesis of endometrial cancer are becoming better understood and have revealed a number of rational strategies, both behavioral and pharmaceutical, for the prevention of both primary and recurrent disease.

Abstract
This review highlights similarities in the epidemiology of endometrial and ovarian cancer, including highly correlated incidence rates and similar risk factor profiles. Factors that decrease risk for both cancers include a late menarche, early age at first birth, giving birth and breastfeeding, and use of oral contraceptives. Short or irregular cycles and late menopause are associated with increased risk for both. Other risk factors that appear to operate in a similar direction include decreased risk associated with IUD use or a tubal ligation, and increased risk associated with obesity, lack of exercise, and use of talc powders in genital hygiene. Estrogen excess is proposed as the underlying mechanism for most endometrial cancers, whereas incessant ovulation has been suggested as the explanation for ovarian cancer. However, an increased number of estimated ovulatory cycles correlates directly with risk for both endometrial and ovarian cancer, suggesting that reproductive tissue turnover with an accumulation of PTEN or p53 mutations represents a possible common mechanism. An immune-based explanation involving mucin proteins represents another common mechanism that could explain additional risk factors. Maintenance of ideal weight, breastfeeding children, use of oral contraceptives, and avoidance of talc powders in genital hygiene are measures that could lower the risk for both types of cancer. Careful selection of patients for prophylactic oophorectomy for those women who are coming to hysterectomy for benign disease is an additional measure to consider for ovarian cancer.

Abstract
Intrauterine devices (IUDs) provide highly effective, long-term, safe, reversible contraception, and are the most widely used reversible contraceptive method worldwide. The levonorgestrel-releasing intrauterine system (LNG-IUS) is a T-shaped IUD with a steroid reservoir containing 52 mg of levonorgestrel that is released at an initial rate of 20 μg daily. It is highly effective, with a typical-use first year pregnancy rate of 0.1% - similar to surgical tubal occlusion. It is approved for 5 years of contraceptive use, and there is evidence that it can be effective for up to 7 years of continuous use. After removal, there is rapid return to fertility, with 1-year life-table pregnancy rates of 89 per 100 for women less than 30 years of age. Most users experience a dramatic reduction in menstrual bleeding, and about 15% to 20% of women become amenorrheic 1 year after insertion. The device's strong local effects on the endometrium benefit women with various benign gynecological conditions such as menorrhagia, dysmenorrhea, leiomyomata, adenomyosis, and endometriosis. There is also evidence to support its role in endometrial protection during postmenopausal estrogen replacement therapy, and in the treatment of endometrial hyperplasia.

Abstract
Pregnancy, breastfeeding, and oral contraceptive pill use interrupt menstrual cycles and reduce endometrial and ovarian cancer risk. This suggests the importance of turnover within Mullerian tissues, where the accumulation of mutations in p53 and PTEN has been correlated with number of cycles. The most common type of endometrial cancer (Type I) is endometrioid and molecular abnormalities include mutations in PTEN, KRAS and β-catenin. The Type I precursor is Endometrial Intraepithelial Neoplasia which displays PTEN defects. Type II endometrial cancer (whose precursors are less clear) includes serous and clear cell tumors and the most common alteration is p53 mutation. For ovarian cancer, histopathologic types parallel endometrial cancer and include serous, mucinous, endometrioid, and clear cell; some molecular features are also shared. The most frequent type of ovarian cancer is high grade serous that often displays p53 mutation and its precursor lesions may originate from normal-appearing fallopian tube epithelium that contains a p53 "signature". Mutations in KRAS, BRAF and PTEN are described in mucinous, endometrioid and low grade serous cancers and these may originate from ovarian cortical inclusion cysts. A consideration of molecular and other pathogenetic features, like epidemiology and histopathology, may provide a better understanding of endometrial and ovarian cancer.

Abstract
The association of contraceptive methods, including oral contraceptives (OC), intrauterine devices (IUD) and tubal sterilization (TS), with overall and site-specific cancer were prospectively investigated in a cohort of 66,661 Chinese women in Shanghai, 76.7% of whom used contraception. During a median follow-up time of 7.5 years, 2,250 women were diagnosed with cancer. Ever-use of any contraceptive method was not associated with overall cancer risk [adjusted hazard ratio (HR(adj)) = 1.02, 95% CI, 0.92-1.12]. Use of any contraceptive method was associated with increased risk of rectal cancer (HR(adj) = 1.68, 95% CI, 1.08-2.62) and reduced risk of thyroid cancer (HR(adj) = 0.63, 95% CI, 0.38-1.04). Risk of gallbladder cancer increased with ever use of OC (HR(adj) = 2.38, 95% CI, 1.26-4.49). IUD use was associated with a possible reduced risk of thyroid cancer (HR(adj) = 0.64, 95% CI, 0.38-1.07). Longer duration of IUD use decreased risk for breast, thyroid and lung cancers. Ever having a TS was associated with increased uterine body cancer (HR(adj) = 2.50, 95% CI, 1.47-4.25) and decreased risk of stomach cancer (HR(adj) = 0.59, 95% CI, 0.39-0.91). We did not find any contraceptive method to be related to the risk of ovarian cancer but the analyses were based on few events. Although chance findings are a likely explanation for some of the associations found in our study, these findings suggest that various contraceptive methods or reproductive patterns may play a role in the etiology of cancer.
