Objective: To estimate the effect of growth in gynecologic oncology fellowships in the United States on surgical volume for trainees and practicing gynecologic oncologists over the next 20 years., Methods: Using 2010-2019 age-specific gynecologic cancer incidence estimates from US Cancer Statistics, significant changes in incidence were identified with Joinpoint software. Statistically significant changes in annual rates were projected forward five years, and these estimates were used to generate projections of cancer cases in the population from the U.S. The number of practicing gynecologic oncologists was projected through 2045 based on current fellowship enrollment. For sensitivity analysis, we varied the number of new fellows and fellowships based on data trends from the last five years., Results: Over the next 20 years, cancer cases will increase by 14 % with the majority being endometrial. With current trainee numbers, the average annual number of new surgical cancer patients per practicing gynecologic oncologist will decrease from 73 to 51 (30 % decrease). An increase of one fellow per year nationally to the total number of trainees will further decrease new surgical cancer cases to 43 cases/gynecologic oncologist annually (41 % decrease). When accounting for one additionally trainee nationally per year over the next 20 years, the average number of oncologic surgical cases per fellow/year will decrease from 208 to 160 (23 % decrease). Under the assumption of no additional fellowship positions, surgical cases will increase from 208 to 226 per fellow/year (9 % increase)., Conclusion: The gynecologic cancer caseload of practicing gynecologic oncologists is estimated to decrease by nearly 41 % and trainee case volume will drop by 23 % over the next 20 years with minimal continued addition of training positions. Careful consideration should be given to creating an appropriate balance between the number of practicing gynecologic oncologists, potential dilution of programs' case volume per trainee, and the effects on the needs of future patients., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: The only disclosure is that Dr. Stephanie Blank is on the ABOG division of gynecologic oncology committee., (Copyright © 2024 Elsevier Inc.

Introduction: COVID-19 and new guidelines during the pandemic affected the gynecologic cancer treatment pathways, resulting in recorded delays and modifications in the treatment protocols. The aim of this study was to determine the impact of the COVID-19 pandemic in one of the major gynecologic cancer care centers in Finland, Tampere University Hospital., Material and Methods: Our retrospective register study included 909 patients that were new gynecologic cancer cases (uterine, cervical, vulvar, vaginal, or ovarian) referred to the Tampere University Hospital Gynecologic Oncology Outpatient Clinic between March 17th, 2018, and March 15th, 2022. The patients were divided into two separate groups depending on their time of referral: time before COVID (March 17th, 2018, to March 15th, 2020), and during COVID (March 16th, 2020, to March 15th, 2022). These groups were compared in terms of patient characteristics, different cancer types and stages, symptoms, and treatment methods., Results: During the COVID-19 pandemic, patients generally suffered from cancer symptoms longer (p < 0.003) and were more likely to be overweight (p = 0.035). The improved multidisciplinary team meeting gave the patients a faster route to their first intervention during COVID (p < 0.05). An insignificant shift toward nonsurgical first interventions and non-curative intent was seen during COVID, but the multidisciplinary team treatment plans were mostly implemented accordingly on both eras. No decrease was seen in the number of new gynecologic cancer cases, and the one-year overall survival remained the same in both groups., Conclusions: Overall, the COVID-19 pandemic did not significantly alter treatment pathways in gynecologic cancer care at Tampere University Hospital. The number of new patients and given treatments remained relatively stable. During COVID, access from referral to cancer treatment was significantly accelerated, which is likely confounded by changes to the multidisciplinary team protocol made in early 2021., (© 2024 The Author(s).

Breast and gynecological cancers are common cancers with high mortality and have profound effects on the various physical functions of women. This study assessed trends in the number of hospitalizations, in-hospital mortality, length of stay (LOS), and hospital charges for female breast and gynecological cancer from 2004 to 2020. The data for this study come from the China Health Statistics Yearbook. Time trends of categorical variables were assessed with the Cochran-Armitage Test. The linear model was used to test for the trend of continuous variables. The hospitalizations for breast cancer increased from 15,204 to 276,387 (P for trend < 0.001) and gynecological cancer increased from 12,418 to 214,956 (P for trend < 0.001). The in-hospital mortality rate due to breast cancer decreased from 1.70 to 1.07% (P for trend < 0.001). Hospitalizations for both breast and gynecological cancer increased clearly, whether in urban or rural. The gap between urban and rural has narrowed. The average cost per hospitalization for breast cancer significantly increased. However, the average LOS for breast cancer gradually decreased (from 17.0 to 10.7 days, P for trend < 0.001). The average cost per hospitalization for gynecological cancer increased significantly. However, this steady downward trend was observed in the average LOS for gynecological cancer (from 10.34 to 6.69 days, P for trend = 0.003). The increase in hospitalizations and medical expenses for breast and gynecological cancer should encourage healthcare policymakers and healthcare system stakeholders to develop more cost-effective approaches to women's cancer management., (© 2024.

Purpose: Indonesia still faces high disease burden from cancer and needs valid gynecologic cancer epidemiology data. The Indonesian Society of Gynecologic Oncology (INASGO) established a web-based gynecologic cancer registry. This research aims to observe and report the situation of INASGO cancer registration information system from 2011 to 2021 and provide the most recent data., Methods: This is a quality assurance research using nonexperimental design and did not perform data manipulation. This study will evaluate comparability, validity, and completeness of cancer registry data. Information was obtained by registration files, direct observation, and interviewing cancer registry supervisors in Cipto Mangunkusumo Hospital, Jakarta., Results: This cancer registry coded its data according to international standards with many participants and large cases registered. A total of 28,692 cases were reported to the cancer registry. Cervical cancer ranked highest (68.6%) with stage III being the most common found. The most frequent age group at diagnosis is 36-55 years. The most valid basic diagnostic of gynecologic cancer is histology of primary malignancy. The main challenge of the INASGO cancer registry is the lack of data validity and completeness because of poor coordination and financial support., Conclusion: INASGO cancer registration information system has good prospects to provide data information of patients with gynecologic cancer in policy or research matters. Poor coordination and limited financial support have to be anticipated for the sake of this cancer registry existence in the future.

Background: The impact of breast carcinoma and genital tract malignancy on the physical and mental health, especially reproductive function, of women aged 15-39 years in the adolescent and young adult (AYA) group is significant. This research aims to analyze the burden of AYA female cancer in various regions and countries globally from 1990 to 2021., Materials and Methods: Epidemiological data were sourced from the Global Burden of Disease (GBD) study 2021. The study analyzed data on female cancers (breast, ovarian, uterine, and cervical) to assess disease burden across different ages, years, and locations, encompassing 21 GBD regions, 195 countries, and five sociodemographic index (SDI) regions., Results: In 2021, AYA female cancer saw 383 241 new cases and 81 679 deaths globally, with 2 975 183 prevalent cases and 4 855 780 disability-adjusted life years. In 2021, Central Latin America recorded the highest age-standardized incidence (ASIR) and prevalence rates (ASPR), whereas South sub-Saharan Africa had the highest age-standardized mortality (ASMR) and disability rates (ASDR). Nations with high SDI typically exhibited elevated ASIR and ASPR, whereas ASMR and ASDR demonstrated inverse patterns. Over the past three decades, ASIR and ASPR of female cancers among AYA women have increased globally. In contrast, the ASMR and ASDR have demonstrated a declining trend. Notably, breast cancer emerged as the most prevalent malignancy among AYA women., Conclusions: Over the past three decades, the ASIR and ASPR of AYA female cancers have consistently increased, significantly burdening this demographic. Additionally, pronounced disparities are evident across different regions and countries, with AYA women in low SDI environments experiencing poorer prognoses compared to their counterparts in high SDI environments. Consequently, it is imperative to enhance interregional collaboration and communication to optimize the overall prognosis of AYA female cancers., (Copyright © 2024 The Author(s).

Background: Observational studies have shown that cholelithiasis and cholecystectomy are associated with the risk of breast cancer (BC) and gynecological cancers, but whether these relationships are causal has not been established and remains controversial., Methods: Our study began with a meta-analysis that synthesized data from prior observational studies to examine the association between cholelithiasis, cholecystectomy, and the risk of BC and gynecological cancers. Subsequently, a two-sample Mendelian randomization (MR) analysis was conducted utilizing genetic variant data to investigate the potential causal relationship between cholelithiasis, cholecystectomy, and the aforementioned cancers., Results: The results of the meta-analysis demonstrated a significant association between cholecystectomy and the risk of BC (risk ratio [RR] = 1.04, 95% confidence interval [CI]: 1.01-1.06, p = 0.002) and endometrial cancer (EC) (RR = 1.26, 95% CI: 1.02-1.56, p = 0.031). Conversely, no significant association was observed between cholelithiasis and the risk of BC, EC, and ovarian cancer. The MR analysis revealed no discernible causal connection between cholelithiasis and overall BC (p = 0.053), as well as BC subtypes (including estrogen receptor-positive/negative). Similarly, there was no causal effect of cholecystectomy on BC risk (p = 0.399) and its subtypes. Furthermore, no causal associations were identified between cholelithiasis, cholecystectomy, and the risk of gynecological cancers (ovarian, endometrial, and cervical cancer [CC]) (all p > 0.05)., Conclusion: This study does not support a causal link between cholelithiasis and cholecystectomy and an increased risk of female cancers such as breast, endometrial, ovarian, and CC., (© 2024 University College London (UCL) and John Wiley & Sons Ltd.)

Background: Numerous recent studies have explored the association between metabolic dysfunction-associated steatotic liver disease (MASLD) and the risk of various extrahepatic cancers. However, the conclusions were inconclusive. The aim of this study was to clarify this relationship by conducting a robust meta-analysis., Methods: Systematic searches were conducted on PubMed, Embase and Web of Science databases to identify relevant cohort studies published prior to February 2024. Hazard ratios (HRs) and their corresponding 95% confidence intervals (95% CIs) were combined using a random-effects model in this meta-analysis., Results: Eighteen cohort studies (approximately 16.7 million participants) were finally included in this meta-analysis. MASLD was linked to a higher risk of extrahepatic cancers, such as gastric (n = 10, HR = 1.47, 95% CI: 1.07-2.01), colorectal (n = 13, HR = 1.33, 95% CI: 1.16-1.53), pancreatic (n = 8, HR = 1.41, 95% CI: 1.11-1.79), biliary tract (n = 5, HR = 1.27, 95% CI: 1.18-1.37), thyroid (n = 6, HR = 1.46, 95% CI: 1.02-2.09), urinary system (n = 10, HR = 1.45, 95% CI: 1.25-1.69), breast (n = 11, HR = 1.17, 95% CI: 1.08-1.26) and female genital organ cancers (n = 10, HR = 1.36, 95% CI: 1.11-1.66). However, there was no statistically significant association between MASLD and the risk of head and neck (n = 6, HR = 1.03, 95% CI: 99-1.07), oesophageal (n = 9, HR = 1.26, 95% CI: 0.86-1.86), lung (n = 9, HR = 1.01, 95% CI: 0.92-1.10), prostate (n = 9, HR = 1.06, 95% CI: 0.94-1.19) or small intestine cancer (n = 2, HR = 1.75, 95% CI: 1.00-3.06)., Conclusions: This latest large-scale meta-analysis indicated that MASLD was associated with an increased risk of various extrahepatic cancers, such as gastric, colorectal, pancreatic, biliary duct, thyroid, urinary system, breast, skin and female genital cancers. Further research is needed to investigate the mechanisms underlying these associations., (© 2024 Stichting European Society for Clinical Investigation Journal Foundation.

Clear-cell carcinomas (CCC) arising from the gynecologic tract (including from the ovary, endometrium, cervix, vulva, or vagina) represent rare but clinically significant entities with intriguing overlapping characteristics. Epidemiologically, CCCs exhibit a predilection for women of Asian ethnicity and are often associated with a previous or synchronous diagnosis of endometriosis. Pathologically, despite originating from different primary organs, CCCs of the gynecologic tract show similar morphologic and immunophenotypic features on traditional histopathology, such as the expression of napsin A and hepatocyte nuclear factor 1β on IHC, without the expression of Wilms tumor 1. Well-described molecular characteristics of these cancers include recurrent mutations in genes such as ARID1A, PIK3CA, and/or PTEN, although significant variations exist across the different anatomic sites. Therapeutically, optimal management remains challenging due to the relative rarity of CCCs and limited subtype-specific clinical trials. Surgery remains the cornerstone of treatment, often complemented by systemic chemotherapy. However, promising drugs targeting angiogenesis or the immune microenvironment have emerged in recent years, leading to clinical successes, and are likely to reshape the therapeutic landscape of gynecologic CCC. This review summarizes the commonalities and disparities in terms of epidemiology, pathology, molecular features, and therapeutic approach, among CCCs of different anatomic origin, offering a foundation for further research and dedicated therapeutic interventions for these malignancies., (©2024 American Association for Cancer Research.)

Background: There are sporadic facility-based reports but an information gap in the cancer burden in the community is apparent. To address this, the Nepal Health Research Council (NHRC) started a Population-based Cancer Registry (PBCR) in 2018 in the country. Thus, this study aims to identify the cancer burden in the female population, especially in the reproductive organs.   Methods: A quantitative database analysis of the Population-based Cancer Registry for year 2018 and 2019 was performed. Data entered in the TSV (Tab-separated values) files were imported to MS Excel and SPSS data Window and variables regrouped before analysis. The national census, WHO standardized population, and registry data were used for the descriptive analysis of the registry variables. Ethical approval was taken from the Ethical Review Board of NHRC., Result: Out of 6854 cancer registries, the female population was 3590 with a male-to-female ratio of 10:11. This registry covers 10.75% of the country’s population. The crude and age-standardized cancer incidence rates were 1.24% and 66.2 per 100,000 for the female population respectively. Reproductive organs (21%) and breast (19.7%) cancers are the most common in females, and out of reproductive organs cervical (58%) and ovarian (25%) cancers are the commonest. Surgery was the main treatment modality (32.7%) with or without chemotherapy and radiotherapy., Conclusions: The burden of cancer is higher in females because of breast cancer. Reproductive organ cancers and breast cancers share an equal burden of around 20% each. The most common female genital cancer is of uterine cervix followed by the ovary.

Objectives: Depression and suicide rates are high among cancer sufferers. Women with breast and gynecological cancer show high levels of distress, depressive symptoms, cognitive impairment, and anxiety. Understanding suicide rates and risk factors in this population would represent a viable tool in planning tailored, prevention strategies. The objective of this study was to estimate suicide rate and identify the determinants of suicide risk in women with breast and other gynecologic cancer., Methods: A systematic research was performed in PubMed and PsycINFO from anytime to September 26, 2023. The following search strategy was used: (Gynaecol* OR Gynecolog*) AND (cancer OR tumor OR tumor OR neoplas* OR malignan*) AND suicid*. In this review, we adhered to PRISMA statement., Results: Nine papers met inclusion criteria. Women with breast or gynecological cancers showed higher suicide rates compared to the general population. Ovarian cancer was associated with higher suicide risk and suicidal ideation compared to other gynecological cancers. The extent of surgical demolition was positively associated with both. Psychological factors, such as self-perceived burden and alexithymia, might also influence suicidal thinking., Conclusions: Women with breast and gynecological cancer are at high risk of suicide. Intervention aimed to reduce burden related to psychological factors might help reducing such risk., (© 2024 John Wiley & Sons Ltd.)

Purpose: To analyze the survival outcomes of female patients with cervical, uterine, and ovarian cancers in Southeast China (Fujian Province) from 2011 to 2020 and to provide a reference basis for prognostic evaluation and prevention of gynecological malignancies., Methods: The data of 5823 patients with cervical, uterine, and ovarian cancers registered in the Fujian Provincial Cancer Prevention and Control System from 2011 to 2020 were enrolled for survival analysis and further stratified by age at diagnosis and township. Survival time was calculated up to March 30, 2022, and relative survival (RS) and age-standardized RS were calculated according to the International Cancer Survival Standards (ICSS)., Results: During 2011-2015, the 5-year RS for cervical, uterine, and ovarian cancers were 64.3 %, 64.2 %, and 44.7 %, respectively, while the age-standardized 5-year RS were 56.8 %, 47.9 %, and 27.9 %, respectively. During 2016-2020, the 5-year RS for cervical, uterine, and ovarian cancers were 72.3 %, 78.9 %, and 50.8 %, respectively, while the age-standardized 5-year RS were 64.5 %, 54.6 %, and 34.2 %, respectively. The 5-year RS for cervical and ovarian cancer all declined with age, while the 5-year RS for uterine cancer was highest at 45-54 years and lowest at 75 years. In addition, survival rates were broadly higher in urban than rural areas., Conclusion: Survival rates for cervical, uterine, and ovarian cancers have generally increased in the population covered by the Fujian Cancer Registry. However, survival rates remain lower than in developed countries. Emphasis should be placed on gynecological cancer screening and the introduction of effective treatments to improve survival rates for gynecological cancers., Competing Interests: Declaration of Competing Interest The authors declare that they have no competing interests., (Copyright © 2024 The Authors.

Objective: Endogenous and exogenous hormonal factors have been associated with female breast, genital, and colorectal cancer risk. The aim of the present study is to conduct an evidence-based evaluation of the fraction of cancers attributable to and prevented by exogenous hormonal (i.e., combined oral contraceptives [COC] and combined estrogen-progestogen menopausal therapy [CEPMT]) and reproductive factors (i.e., parity and breastfeeding) in Italy., Study Design: We calculated the population attributable and prevented fractions combining relative risks and prevalence of exposure in Italian women. Italian cancer incidence and mortality data were extracted from national sources and used to estimate the number of cancer cases and deaths attributable to reproductive factors and exogenous hormones in Italy in 2020. For long-term effects, a 20-year latency period was considered., Results: COC were responsible for 4.4 % of breast and 10.9 % of cervical cancers in women aged 15-44, but also avoided 6.4 % of endometrial, 5.6 % of ovarian, and 2.9 % of colorectal cancers in women of all ages. Overall, COC use prevented 1174 cancer diagnoses and 577 cancer deaths. CEPMT caused 0.4 % of breast cancers at age 45-69. Low parity accounted for 8.1 %, 11.8 % and 15.5 % of breast, endometrial and ovarian cancers, respectively (6267 cases, 1796 deaths). Breastfeeding avoided 6.4 % of breast cancers (3775 cases, 897 deaths)., Conclusions: Our analysis quantified the complex effects of hormonal and reproductive factors on cancer burden in Italian women., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Background: The levonorgestrel-releasing intrauterine device (LNG-IUD) is widely used for the treatment of menorrhagia, dysmenorrhea, and for contraception. However, the association between the use of LNG-IUD and the risk of site-specific gynecologic and breast cancers remains inconclusive., Objective: We aim to address this knowledge gap by investigating whether the use of LNG-IUD is associated with a significant risk of site-specific gynecologic and breast cancers. This will be achieved by accessing the nationwide Swedish Registers, with consideration given to the influence and potential interaction of family history of cancer., Study Design: A total of 514,719 women aged 18 to 50 years who have used LNG-IUD between July 2005 and December 2018 were identified from the Swedish Prescribed Drug Register and randomly matched with 1,544,157 comparisons who did not use LNG-IUD at a ratio of 1:3. The propensity score was calculated and matched among women who used LNG-IUD and the matched comparisons. The follow-up period started from the date of the first prescription of LNG-IUD for users as well as for their matched comparisons and ended at the date of diagnosis of gynecologic and breast cancers, date of death from any cause, and the end of the study period, whichever came first. The Cox proportional hazard model with a competing risk analysis was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). Additive interaction was calculated as the relative excess risk for interaction, while multiplicative interaction was calculated by including a product term in the regression model., Results: The use of LNG-IUD was associated with a 13% higher risk of breast cancer (adjusted HR, 1.13; 95% CI, 1.10-1.17), a 33% lower risk of endometrial cancer (adjusted HR, 0.67; 95% CI, 0.56-0.80), a 14% lower risk of ovarian cancer (adjusted HR, 0.86; 95% CI, 0.75-0.99), and a 9% reduced risk of cervical cancer (adjusted HR, 0.91; 95% CI, 0.84-0.99) compared to women who did not use LNG-IUD. A significant additive interaction between LNG-IUD use and family history of cancer was observed in breast cancer, indicating a relative 19% excess risk for interaction (P<.002), and 1.63 additional cases per 10,000 person-years., Conclusion: The risk of gynecologic and breast cancers exhibits a site-specific effect among LNG-IUD users. It is important to note that the observed effect is small for breast cancer and the results are limited by the observational study design. Clinical recommendations regarding the use of LNG-IUD should carefully weigh its potential benefits and risks. Close monitoring is advisable for the potential development of breast cancer, particularly among women with a family history of breast cancer., (Copyright © 2024 The Authors.

Objective: To analyse the global burden, trends and cross-country inequalities of female breast and gynaecologic cancers (FeBGCs)., Design: Population-Based Study., Setting: Data sourced from the Global Burden of Disease Study 2019., Population: Individuals diagnosed with FeBGCs., Methods: Age-standardised mortality rates (ASMRs), age-standardised Disability-Adjusted Life Years (DALYs) rates (ASDRs) and their 95% uncertainty interval (UI) described the burden. Estimated annual percentage changes (EAPCs) and their confidence interval (CI) of age-standardised rates (ASRs) illustrated trends. Social inequalities were quantified using the Slope Index of Inequality (SII) and Concentration Index., Main Outcome Measures: The main outcome measures were the burden of FeBGCs and the trends in its inequalities over time., Results: In 2019, the ASDRs per 100 000 females were as follows: breast cancer: 473.83 (95% UI: 437.30-510.51), cervical cancer: 210.64 (95% UI: 177.67-234.85), ovarian cancer: 124.68 (95% UI: 109.13-138.67) and uterine cancer: 210.64 (95% UI: 177.67-234.85). The trends per year from 1990 to 2019 were expressed as EAPCs of ASDRs and these: for Breast cancer: -0.51 (95% CI: -0.57 to -0.45); Cervical cancer: -0.95 (95% CI: -0.99 to -0.89); Ovarian cancer: -0.08 (95% CI: -0.12 to -0.04); and Uterine cancer: -0.84 (95% CI: -0.93 to -0.75). In the Social Inequalities Analysis (1990-2019) the SII changed from 689.26 to 607.08 for Breast, from -226.66 to -239.92 for cervical, from 222.45 to 228.83 for ovarian and from 74.61 to 103.58 for uterine cancer. The concentration index values ranged from 0.2 to 0.4., Conclusions: The burden of FeBGCs worldwide showed a downward trend from 1990 to 2019. Countries or regions with higher Socio-demographic Index (SDI) bear a higher DALYs burden of breast, ovarian and uterine cancers, while those with lower SDI bear a heavier burden of cervical cancer. These inequalities increased over time., (© 2024 John Wiley & Sons Ltd.)

Objectives: This study aimed to investigate the changes in the incidence and mortality trends of ovarian cancer (OC), cervical cancer (CC) and uterine cancer (UC) in the Fujian Province, southeastern China., Design: Provincial, population-based, retrospective observational study., Setting: Fujian province, southeastern China between 2011-2020., Participants: From 2011 to 2020, 6178 new cases and 2037 deaths caused by 3 gynaecological cancers were eligible for analysis., Primary and Secondary Outcome Measures: The primary outcome measures were the incidence and mortality rates, including the age-standardised incidence rate (ASIR) and age-standardised mortality rate (ASMR), of three gynaecological cancers. The secondary outcome measure was the prevalence (average annual per cent changes (AAPC))., Results: The incidence of all three gynaecological cancers increased from 2011 to 2020. CC had the slowest upward trend, with an AAPC of 2.54% over the period. However, it had the highest ASIR among the 3 cancers in 2020 (10.41/100 000). UC showed a rapid increase, with an AAPC of 15.15% from 2016 to 2020. While the mortality rate of UC remained stable, both CC and OC also exhibited rising trends, with the CC having the highest ASMR (3.05/100 000) in 2020. The ASMR for CC increased rapidly, with the highest AAPC of 5.51%. Conversely, changes in the ASMR for UC were not statistically significant (p=0.601). Moreover, high incidence rates were more common among perimenopausal women and older participants in the respective cancer groups where the increased mortality was observed., Conclusions: Gynaecological cancer burden remains a public health issue in Fujian Province, with an increasing incidence. Improving the healthcare system and promoting a healthy lifestyle should be highlighted to reduce the cancer burden., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Alzheimer's disease (AD) manifests with a higher rate of occurrence in women. Previous epidemiological studies have suggested a potential association between AD and gynecological cancers, but the causal relationship between them remains unclear. This study aims to explore the causal link between 12 types of gynecological cancers and AD using a bidirectional Mendelian randomization (MR) approach., Methods: We obtained genetic correlation tools for AD using data from the most extensive genome-wide association study. Genetic correlation data for 12 types of gynecological cancers were also sourced from the Finnish Biobank. These cancers include breast cancer (BC), cervical adenocarcinoma (CA), cervical squamous cell carcinoma (CSCC), cervical cancer (CC), endometrial cancer (EC), ovarian endometrioid carcinoma (OEC), ovarian cancer (OC), ovarian serous carcinoma (OSC), breast carcinoma in situ (BCIS), cervical carcinoma in situ (CCIS), endometrial carcinoma in situ (ECIS), and vulvar carcinoma in situ (VCIS). We used the inverse-variance weighted (IVW) model for causal analysis and conducted horizontal pleiotropy tests, heterogeneity tests, MR-PRESSO tests, and leave-one-out analyses to ensure the robustness of our results. We also applied replication analysis and meta-analysis to further validate our experimental results., Results: The study found that EC (P &#95;IVW =0.037, OR [95% CI] = 1.032 [1.002, 1.064]) and CCIS (P &#95;IVW = 0.046, OR [95% CI] = 1.032 [1.011, 1.064]) increase the risk of AD, whereas OC was negatively correlated with AD (P &#95;IVW = 0.016, OR [95% CI] = 0.974[0.954, 0.995]). In reverse MR analysis, AD increased the risk of CC (P &#95;IVW = 0.039, OR [95% CI] = 1.395 [1.017, 1.914]) and VCIS (P &#95;IVW = 0.041, OR [95% CI] = 1.761 [1.027, 2.021]), but was negatively correlated with OEC (P &#95;IVW = 0.034, OR [95% CI] = 0.634 [0.417, 0.966]). Sensitivity analysis results demonstrated robustness. These findings were further substantiated through replication and meta-analyses., Conclusions: Our MR study supports a causal relationship between AD and gynecological cancers. This encourages further research into the incidence of gynecological cancers in female Alzheimer's patients and the active prevention of AD., (© 2024. The Author(s).)

Gynecological cancer significantly affect the health of women. This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers. We searched PubMed, Embase, Web of Science, SinoMed, and SEER for survival analyses of cancer registration data of cervical, endometrial, and ovarian cancers published between 1980 and 2022. Globally, the highest 5-year observed survival rate for cervical cancer was 76.5% in Anshan, Liaoning, China (2008-2017). The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland (1995-1999, 82.5%) and Singapore (1988-1992, 62.0%). The 5-year relative survival rate of cervical cancer patients was higher in Haining, Zhejiang, China (2011-2014, 85.8%). Korea ranked first at 89.0% and 64.5% for endometrial and ovarian cancers, respectively. Survival rates have improved for cervical, endometrial, and ovarian cancers. Patients aged ≥ 75 years and those with advanced-stage disease had the worst 5-year survival rates. Survival rates were better for squamous cell carcinoma in cervical cancer, for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer, and for germ cell and sex-cord stromal tumors in ovarian cancer. Over the past four decades, the survival rates of gynecological cancers have increased globally, with notable increases in cervical and endometrial cancers. Survival rates are higher in developed countries, with a slow-growing trend. Future studies should focus on improving survival, especially in ovarian cancer patients., (Copyright © 2024 The Editorial Board of Biomedical and Environmental Sciences. Published by China CDC.

Background: The incidence and mortality of gynaecological cancers can significantly impact women's quality of life and increase the health care burden for organisations globally. The objective of this study was to evaluate global inequalities in the incidence and mortality of gynaecological cancers in 2022, based on The Global Cancer Observatory (GLOBOCAN) 2022 estimates. The future burden of gynaecological cancers (GCs) in 2050 was also projected., Methods: Data regarding to the total cases and deaths related to gynaecological cancer, as well as cases and deaths pertaining to different subtypes of GCs, gathered from the GLOBOCAN database for the year 2022. Predictions for the number of cases and deaths in the year 2050 were derived from global demographic projections, categorised by world region and Human Development Index (HDI)., Results: In 2022, there were 1 473 427 new cases of GCs and 680 372 deaths. The incidence of gynecological cancer reached 30.3 per 100 000, and the mortality rate hit 13.2 per 100 000. The age-standardised incidence of GCs in Eastern Africa is higher than 50 per 100 000, whereas the age-standardised incidence in Northern Africa is 17.1 per 100 000. The highest mortality rates were found in East Africa (ASMR (age-standardised mortality rates) of 35.3 per 100 000) and the lowest in Australia and New Zealand (ASMR of 8.1 per 100 000). These are related to the endemic areas of HIV and HPV. Very High HDI countries had the highest incidence of GCs, with ASIR (age-standardised incidence rates) of 34.8 per 100 000, and low HDI countries had the second highest incidence rate, with an ASIR of 33.0 per 100 000. Eswatini had the highest incidence and mortality (105.4 per 100 000; 71.1 per 100 000) and Yemen the lowest (5.8 per 100 000; 4.4 per 100 000). If the current trends in morbidity and mortality are maintained, number of new cases and deaths from female reproductive tract tumours is projected to increase over the next two decades., Conclusions: In 2022, gynaecological cancers accounted for 1 473 427 new cases and 680 372 deaths globally, with significant regional disparities in incidence and mortality rates. The highest rates were observed in Eastern Africa and countries with very high and low HDI, with Eswatini recording the most severe statistics. If current trends continue, the number of new cases and deaths from gynaecological cancers is expected to rise over the next two decades, highlighting the urgent need for effective interventions., Competing Interests: Disclosure of interest: The authors completed the ICMJE Disclosure of Interest Form (available upon request from the corresponding author) and disclose no relevant interests., (Copyright © 2024 by the Journal of Global Health.

Objective: To examine patterns of Accountable Care Organizations (ACO) leakage, the receipt of healthcare by ACO-assigned patients from institutions outside assigned ACO network, among patients with gynecologic cancer. ACO leakage was estimated as rates of patients seeking care external to their ACO assignment. Factors associated with ACO leakage were identified and cost differences within the first year of cancer diagnosis described., Methods: Medicare 5% data (2013-2017) was used to quantify rates of leakage among gynecologic cancer patients with stable ACO assignment. Crude and multivariable adjusted risk ratios of ACO leakage risk factors were estimated using log-binomial regression models. Overall and cancer-specific spending differences by ACO leakage status were compared using Wilcoxon rank-sum test., Results: Overall incidence of ACO leakage was 28.1% with highest leakage for outpatient care and uterine cancer patients. ACO leakage risk was 56% higher among Black relative to White patients, and 77% more for those in higher relative to lowest quintiles of median household income. Leakage decreased by 3% and 8% with each unit increase in ACO size and number of subspecialists, respectively. Healthcare costs were 19.5% higher for leakage patients., Conclusions: ACO leakage rates among gynecologic cancer patients was overall modest, with some regional and temporal variation, higher leakage for certain subgroups and substantially higher Medicare spending in inpatient and outpatient settings for patients with ACO leakage. These findings identify targets for further investigations and strategies to encourage oncologists to participate in ACOs and prevent increased health care costs associated with use of non-ACO providers., Competing Interests: Declaration of competing interest The authors report no conflicts of interest., (Published by Elsevier Inc.)

Objective: To clarify the epidemiologic characteristics and risk of other tumors in survivors of gynecological tumors., Materials and Methods: This is a retrospective study based on the Surveillance, Epidemiology, and End Results database (SEER)., Results: The morbidity of other malignant tumors in patients with gynecological cancer was 8.07%. The most common subsequent tumors are breast, lung, colorectal, thyroid, and bladder cancers. Taking the incidence rate of the general population as reference, the second tumor with the highest relative risk in patients with cervical cancer is vulvar cancer. Bladder cancer is the second tumor with the highest relative risk value both in patients with corpus and ovarian cancer. The median period from the diagnosis of the initial tumor to the diagnosis of the second tumor was 5 years. Most patients with other tumors following gynecological cancer showed worse prognosis than patients with gynecological tumors only. However, thyroid cancer following ovarian cancer is a protective factor in survival., Conclusion: Patients with gynecological tumors have a significantly higher risk of malignant tumors in other systems compared to ordinary population. It is necessary to be vigilant against subsequent high-risk tumors and tumors with poor prognosis within 5 years of initial diagnosis., (© 2024.

Background: This study aimed to explore the association between occupational exposure to diesel exhaust (DE) and gynaecological and breast cancers., Methods: A systematic review was performed to identify cohort studies reporting results on the association between occupational exposure to DE and risk of gynaecological and breast cancers. STROBE guidelines and PECOS criteria were followed. We identified 6 studies for breast cancer (BC), 4 for cervical cancer (CC), 4 for endometrial cancer (EC) and 7 for ovarian cancer (OC). Random-effects meta-analyses were conducted on the relationship between DE exposure and BC, CC, EC, and OC risk; 95% confidence intervals (CI) and prediction intervals (PI) were reported. We investigated between-study heterogeneity and potential publication bias using Egger's test., Results: No associations were observed between occupational DE exposure and risk of BC [RR=0.93; CI: 0.77-1.13; PI:0.50-1.73, I2=80.31%], EC [RR=0.89; CI: 0.75-1.05; PI:0.61-1.30, I2=0.78%], and OC [RR=1.08; CI: 0.89-1.32, PI: 0.76-1.56, I2=11.87%]. A weak association was observed for CC [RR=1.41; CI: 1.17-1.17; PI:0.85-2.30, I2=6.44%]. No between-study heterogeneity or publication bias was detected., Conclusions: This study identified an association between DE exposure and CC, which was not adjusted for potential confounders. No evidence of an association was found with BC, EC, and OC.

Background: Female gynecological cancers represent a serious public health problem, with 1,398,601 new diagnoses and 671,875 deaths per year worldwide. Antipsychotics are often used in psychiatric disorders, including schizophrenia, bipolar disorder, and major depression. It is estimated that the prescription of these drugs is linked to 1,800 deaths a year in the United States, but their association with cancer remains controversial., Methods: We searched PubMed, Scopus, and Web of Science databases for studies reporting the correlation in the incidence risk of gynecological cancer by antipsychotic use. We used DerSimonian and Laird random-effect models to compute logit transformed odds ratio (OR) for the primary binary endpoint with 95% confidence interval (CI). Heterogeneity was assessed through effect size width along with I-squared and Tau-squared statistics. Review Manager 5.4.1. was used for statistical analyses. A p-value of < 0.05 denoted statistically significant., Results: 50,402 patients were included, of whom 778 (1,54%) took antipsychotic medication for at least 1 year. 1,086 (2,15%) with ovarian cancer and 49,316 (97,85%) with endometrial cancer. Antipsychotic use (OR 1.50; 1.06 to 2.13 95% CI; p-value 0.02), hypertension (OR 1.50; 95% CI 1.06 to 2.13; p-value < 0.01), nulliparity (OR 1.98; 95% CI 1.53 to 2.57; p-value < 0.01) and multiparity (OR 0.53; 95% CI 0.41 to 0.69; p-value < 0.01) showed significantly different distributions between groups of cancer and cancer-free patients. The primary endpoint of incidence risk of gynecological cancer by antipsychotic therapy showed a statistically significant difference (OR 1.67; 95% CI 1.02 to 2.73; p-value < 0.05) against the use of antipsychotic drugs., Conclusions: Our meta-analysis showed that the use of antipsychotic drugs increases the risk of gynecological cancers, particularly endometrial cancer. This result should be weighed against the potential effects of treatment for a balanced prescribing decision., (© 2024. The Author(s).)

Small-cell neuroendocrine carcinomas (SCNECs) of the female genital tract are rare and aggressive tumors that are characterized by a high rate of recurrence and poor prognosis. They can arise from various sites within the female genital tract, including the cervix, endometrium, ovary, fallopian tube, vagina, and vulva. They are composed of cells with neuroendocrine features, such as the ability to produce and secrete hormones and peptides, and a high mitotic rate. Immunohistochemical staining for neuroendocrine markers, such as chromogranin A, synaptophysin, and CD56, can aid in the diagnosis of these tumors. This article provides an overview of the epidemiology, etiology, and risk factors associated with these tumors, as well as their clinical presentation, cellular characteristics, diagnosis, and finally the current treatment options for SCNECs, including surgery, chemotherapy, and radiation therapy, alone or in combination., (© 2024 British Society for Neuroendocrinology.)

Background: This study aims to assess the long-term trends in the burden of three major gynecologic cancers(GCs) stratified by social-demographic status across the world from 1990 to 2019. To assess the trends of risk factor attributed mortality, and to examine the specific effects of age, period, cohort behind them in different regions., Methods: We extracted data on the mortality, disability-adjusted life years(DALYs), and age-standardized rates(ASRs) of cervical cancer(CC), uterine cancer(UC), and ovarian cancer(OC) related to risks from 1990 to 2019, as GCs burden measures. Age-period-cohort analysis was used to analyze trends in attributable mortality rates., Results: The number of deaths and DALYs for CC, UC and OC increased since 1990 worldwide, while the ASDRs decreased. Regionally, the ASDR of CC was the highest in low SDI region at 15.05(11.92, 18.46) per 100,000 in 2019, while the ASDRs of UC and OC were highest in high SDI region at 2.52(2.32,2.64), and 5.67(5.16,6.09). The risk of CC death caused by unsafe sex increased with age and then gradually stabilized, with regional differences. The period effect of CC death attributed to smoking showed a downward trend. The cohort effect of UC death attributed to high BMI decreased in each region, especially in the early period in middle, low-middle and low SDI areas., Conclusions: Global secular trends of attributed mortality for the three GCs and their age, period, and cohort effects may reflect the diagnosis and treatment progress, rapid socioeconomic transitions, concomitant changes in lifestyle and behavioral patterns in different developing regions. Prevention and controllable measures should be carried out according to the epidemic status in different countries, raising awareness of risk factors to reduce future burden., (© 2024.

This retrospective cohort study aimed to determine the prevalence of anemia among patients with gynecological cancer prior to any treatment and to identify contributing factors associated with anemia in this group. We retrospectively analyzed data from female patients aged 18 and above, diagnosed with various forms of gynecological cancer at The Affiliated Hospital of Southwest Medical University between February 2016 and March 2021. Anemia was assessed based on the most recent CBC results before any cancer treatment. Eligibility was based on a definitive histopathological diagnosis. Key variables included demographic details, clinical characteristics, and blood counts, focusing on hemoglobin levels. Statistical analysis was conducted using logistic regression models, and anemia was defined as hemoglobin levels below 12 g/dL for women, according to WHO criteria. Of the 320 participants, a significant prevalence of anemia was found. Correlations between anemia and factors like age, educational level, and biological markers (iron, folic acid, and vitamin B12 levels) were identified. In our study, we found that the prevalence of anemia among patients with gynecological cancer prior to any treatment was 59.06%, indicating a significant health concern within this population. The study highlights a significant prevalence of anemia in patients with gynecological cancer, emphasizing the need for regular hemoglobin screening and individualized management. These findings suggest the importance of considering various characteristics and clinical variables in anemia management among this patient group. Further studies are needed to explore the long-term effects of these factors on patient outcomes and to develop targeted interventions., (© 2024. The Author(s).)

The effects of ovarian stimulation on breast and gynecological tumor incidence remain controversial. Therefore, the aim of this meta-analysis was to study the risk of cancer in ovarian stimulation. Of the 22713 studies initially identified, 28 were eligible for inclusion. The results revealed that the impact of ovarian cancer (RR = 1.33, [1.05; 1.69]) and cervical cancer (RR = 0.67, [0.46; 0.97]) is significant among the overall effects. In subgroup analysis, in the nulliparous population (RR = 0.81 [0.68; 0.96]) was the protective factor for the breast cancer. In the Caucasians subgroup (RR = 1.45, [1.12; 1.88]), the ovarian cancer incidence was statistically significant. In the Asian subgroup (RR = 1.51, [1.00; 2.28]), the endometrial cancer incidence was statistically significant. In the subgroup of Asians (RR = 0.55 [0.44; 0.68]) and the multiparous population (RR = 0.31, [0.21; 0.46]), them can be the statistically protective factor for the cervical cancer., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Background: Numerous observational studies have investigated the potential link between hypertensive disorders of pregnancy (HDPs) and the subsequent risks of gynecologic tumors, yet the findings have been inconsistent. In this study, we utilized Mendelian randomization (MR) approach to assess the influence of HDPs on the future risks of ovarian, cervical, endometrial, and breast cancer and uterine fibroids, controlling for confounding factors., Methods: The genome-wide association studies (GWAS) summary data relevant to HDPs was obtained from the FinnGen databases (10,736 cases and 136,325 controls). Gynecologic tumor outcomes were extracted from the IEU Open GWAS project and UK Biobank (47,690 cases and 1, 092,073 controls). The inverse variance weighted (IVW) approach was selected as the principal method for MR analysis, supplemented by MR-Egger, weighted median, weighted model, simple model methods, MR pleiotropy residual sum and outlier (MR-PRESSO) test, and leave-one-out method. Multivariate MR (MVMR) analysis was conducted after adjusting systolic blood pressure (SBP), body mass index (BMI) and type 2 diabetes mellitus (T2DM)., Results: Our univariate MR analysis (UVMR) results revealed no significant relationship between HDPs and the risks of ovarian cancer (odds ratio [OR] = 0.924, p = 0.360), cervical cancer (OR = 1.230, p = 0.738), endometrial cancer (OR = 1.006, p = 0.949), uterine fibroids (OR = 1.155, p = 0.158), and breast cancer (OR = 0.792, p = 0.241) by IVW test. Similar results were observed in gestational hypertension and preeclampsia/eclampsia. Additionally, our study detected neither heterogeneity nor pleiotropy. MVMR analysis also provided no evidence of a causal association between HDPs and common gynecologic tumors after adjusting SBP, BMI, and T2DM., Conclusion: We discovered no causal relationship between HDPs and ovarian, cervical, endometrial, breast cancer, and uterine fibroids in European populations. However, present analysis did not explore the effect of HDPs on the subtypes of gynecologic tumors across varied ethnic populations, which may require additional research., (© 2024 The Author(s).

Background: Due to the paucity of reliable data to determine the components of family-based comprehensive care for cancer in India, we explored the familial implications of gynaecological and breast cancer diagnosis and treatment through a mixed-method study., Methods: The mixed method study included 130 women aged above 18 with a confirmed diagnosis of gynaecological or breast cancer recruited from three selected tertiary hospitals in Kerala, India. Information on quality of life (36-Item Short Form Survey (SF-36)), psychological distress (distress thermometer), and the familial, interpersonal, social, and community impacts of cancer (semi-structured interview guide) were elicited. Linear regression was used to identify the factors associated with distress and the factors were explored further using thematic analysis., Results: Patients included in the study (n = 130; mean age 57.5 years) had moderate or mild (66.9%) to severe (25.4%) distress. Concerns about work (93%), difficulty in; home care and housing (82%), care for dependents (65%), unempathetic family (87.6%), isolation (70%), and body image (65%) were major reasons for their distress. Physiological, social, and family-related stressors among the respondents included challenges in physical functioning, intense physical symptoms like fatigue, loss of appetite and sleep, role restrictions, alterations in family responsibilities, functional dependency, inadequate family support, challenges in social and interpersonal interactions, and an unsupportive work environment., Conclusion: Cancer is a health crisis that involves psychological, social, and economic distress, compelling professionals to design multifaceted individualized care packages rather than only concentrating on medical management to alleviate their distress., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Hair products often contain chemicals like para-phenylenediamine (PPD) and endocrine-disrupting chemicals (EDCs); giving rise to concerns about the possible adverse effects such as hormonal disturbances and carcinogenicity. The objective of this systematic review was to evaluate the association between the use of different hair products and benign and malignant gynecological conditions. Studies were identified from three databases including PubMed, Embase, and Scopus, and evaluated in accordance with PRISMA guidelines. The risk of bias was assessed using the Newcastle-Ottawa Scale. A total of 17 English-language studies met the inclusion criteria. Associations of hair relaxer or hair dye use with breast and ovarian cancer were observed in at least one well-designed study, but these findings were not consistent across studies. Further sub-analysis showed 1.08 times (95 % CI: 1.01-1.15) increased risk of breast cancer in females with permanent hair dye use. Chang et al. reported strong association between uterine cancer risk and hair relaxer use (HR 1.8, 95 % CI: 1.12-2.88), with no observed association with hair dye use. Studies conducted by Wise et al. and James-Todd et al. for benign gynecological conditions; including uterine leiomyoma (IRR 1.17, 95 % CI: 1.06-1.30), early onset of menarche (RR 1.4, 95 % CI: 1.1-1.9), and decreased fecundability (FR 0.89, 95 % CI: 0.81-0.98) revealed positive associations with hair relaxer use, but these findings were based on small sample sizes. In summary, the available evidence regarding personal use of hair products and gynecological conditions is insufficient to determine whether a positive association exists., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Objectives: To examine if racial differences in cardiovascular health (CVH) are associated with cardiovascular disease (CVD) disparities among women with breast and gynecologic cancers., Sample & Setting: The sample consisted of 252 Black women and 93 White women without a self-reported history of cancer or CVD who developed a breast or gynecologic malignancy. Women who developed CVD before their cancer diagnosis were excluded., Methods & Variables: CVH was classified using metrics of the American Heart Association's Life's Simple 7 framework. Metrics were summed to create a total CVH score (0-7). Associations among race, ideal CVH (score of 5-7), and CVD incidence following cancer diagnosis were estimated with Cox proportional hazards models., Results: Ideal CVH was similar between Black women (33%) and White women (37%). Race and CVH were not associated with CVD incidence., Implications for Nursing: In a small sample of women diagnosed with breast and gynecologic cancers, racial disparities in CVH and CVD incidence were not observed. Additional investigation of potential confounders relating to social determinants of health tied to the construct of race is warranted.

The purpose of this study was to assess the risks of hyperthyroidism and hypothyroidism related to gynecological cancers. Population-based retrospective cohort study. We conducted a cohort study using the Taiwan National Health Insurance Research Database to explore hyperthyroidism and hypothyroidism associated with site-specific gynecologic cancers in women from January 1, 2000 to December 31, 2018. The examined gynecologic cancers included endometrial (EC), uterine corpus cancer (UC), and ovarian cancer (OC). The incidence and hazard ratios were quantified using Cox proportional hazards models. The incidence of developing gynecological (Gyn) cancers in the hyperthyroid and hypothyroid women was 0.29 and 0.44 per 1000 person-years, which was 0.86 fold lower and 1.13 fold higher than that in the comparison cohort (p < 0.001). Compared with patients aged 20-40 years, patients in older age groups had a lower and higher risk of developing Gyn cancers (for hyperthyroid, 40-65 years: adjusted hazard ratio (aHR) = 0.82; > 65 years: aHR = 0.94; for hypothyroid, adjusted hazard ratio (aHR) = 1.26; > 65 years: aHR = 1.38). Compared with the non-hypothyroid women and non-hyperthyroid women beyond 6 years of follow-up, hypothyroid and hyperthyroid women showed decreased risk of Gyn cancers. Medication treatment for hyperthyroid and hypothyroid disease did not showed significant association in subgroup analyses (aHR = 0.99 and 0.80, respectively). Our results show that women with hyperthyroidism have a significantly reduced risk of gynecological cancers, whereas women with hypothyroidism have a slightly increased risk of gynecological cancers suggesting an association between thyroid function level and risk of gynecological cancers., (© 2024.

Objective: To evaluate pre-operative predictors of early (<30 days) severe complications (grade Dindo 3+) in patients with gynecological malignancy submitted to pelvic exenteration (PE)., Methods: We retrospectively analyzed 129 patients submitted to surgery at Fondazione Policlinico Gemelli between 2010 and 2019. We included patients affected by primary or recurrent/persistent cervical, endometrial, or vulvar/vaginal cancers. Post-operative complications were graded according to the Dindo classification. Logistic regression was used to analyze potential predictors of complications., Results: We performed 63 anterior PE, 10 posterior PE, and 56 total PE. The incidence of early severe post-operative complications was 27.9% (n=36), and the early mortality rate was 2.3% (n=3). More frequent complications were related to the urinary diversion and intestinal surgery. In univariable analysis, hemoglobin ≤10 g/dL (odds ratio [OR]=4.2; 95% confidence interval [CI]=1.65-10.7; p=0.003), low albumin levels (OR=3.9; 95% CI=1.27-12.11; p=0.025), diabetes (OR=4.15; 95% CI=1.22-14.1; p=0.022), 2+ comorbidities at presentation (OR=5.18; 95% CI=1.49-17.93; p=0.012) were predictors of early severe complications. In multivariable analysis, only low hemoglobin and comorbidities at presentation were independent predictors of complications., Conclusion: Pelvic exenteration is an aggressive surgery characterized by a high rate of post-operative complications. Pre-operative assessment of comorbidities and patient health status are crucial to better select the right candidate for this type of surgery., Competing Interests: No potential conflict of interest relevant to this article was reported., (© 2024.

Introduction: A strong association was previously established between body mass index (BMI) and female reproductive system tumors; however, the causal relationship is unclear. We conducted a Mendelian randomization (MR) study to further explore this association. Methods: Genetic information for BMI was retrieved from a published genome-wide association study involving 339,224 participants. Genetic associations with five common female reproductive system tumors were obtained from the FinnGen, UK Biobank studies, and other large consortia. Results: Genetic predisposition towards BMI exhibits a significant association with multiple tumors of the female reproductive system. Specifically, for every 1-unit increase in BMI log-transformed odds ratio (OR). The OR fluctuations overall for patients with breast cancer ranged from 0.661 to 0.996 (95% confidence interval [CI],0.544-1.000, P < 0.05). When stratified by estrogen receptor (ER) status, the OR for patients with ER (+) breast cancer ranged from 0.782 to 0.844 (95% CI, 0.616-0.994, P < 0.05) and that for those with ER (-) breast cancer ranged from 0.663 to 0.789 (95% CI, 0.498-0.991, P < 0.05). Additionally, ORs were as follows for cancer types: 1.577-1.908 (95% CI, 1.049-2.371, P < 0.05) for endometrial carcinoma; 1.216-1.303 (95% CI, 1.021-1.591, P < 0.05) for high-grade serous ovarian cancer; 1.217 (95% CI, 1.034-1.432, P < 0.05) for low-grade malignant serous ovarian cancer; and 1.502 (95% CI, 1.112-2.029, P < 0.05) for endometrioid ovarian carcinoma. Furthermore, our findings indicated that genetic predisposition towards BMI did not exhibit a causal association with uterine fibroids, cervical precancerous lesions, or cervical cancer itself. Conclusion: A genetic association was established between a high BMI and high risk of developing multiple tumors of the female reproductive system and their associated subtypes. This underscores the significance of taking measures to prevent reproductive system tumors in women who have a high BMI., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Participation in clinical trials may help mitigate disparate cancer outcomes. Thus, ensuring equitable access to clinical trials is a major priority for national cancer organizations., Objective: This study aimed to examine clinical trial eligibility criteria that may adversely affect the enrollment of underrepresented groups and assess the availability of demographic information in published gynecologic oncology studies., Study Design: ClinicalTrials.gov was searched for gynecologic oncology studies conducted between 1997 and 2021. Each study's inclusion and exclusion criteria were reviewed to determine whether demographic factors were used for enrollment screening. For published studies, demographic variables that were reported were identified. The expected clinical trial enrollment based on disease incidence and mortality was compared with the observed trial enrollment based on race., Results: There were 1597 gynecologic oncology studies: 883 (55%) from ovarian cancer studies, 336 (21%) from cervical cancer studies, 262 (17%) from uterine cancer studies, and 116 (7%) from multisite gynecologic oncology studies. Of the 581 published studies, 554 (95%) reported age, 363 (63%) reported race, and 171 (29%) reported ethnicities. Cervical cancer studies were most likely to report demographic information, including race (P=.026) and ethnicity (P<.001). During the study period, 189 studies (12%) excluded patients based on the language spoken. Industry-sponsored trials (odds ratio, 0.07; 95% confidence interval, 0.02-0.30) and organization-sponsored trials (odds ratio, 0.40; 95% confidence interval, 0.22-0.73) were less likely to exclude patients because of language than investigator-initiated trials. A minority of patients (37%) in cervical cancer trials were of White race, compared with 85% of patients in uterine cancer trials and 82% of patients in ovarian cancer trials., Conclusion: Over the last 3 decades, 1 in 10 gynecologic oncology trials excluded patients because of language. Race and ethnicity were reported in more than half of the available studies. Initiatives to increase transparency in recruiting underrepresented patients and reporting demographic data are urgently needed., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Importance: Racial and ethnic disparities in clinical trial enrollment are unjust and hinder development of new cancer treatments., Objective: To examine the association of race and ethnicity with clinical trial enrollment among women with endometrial, ovarian, or cervical cancer., Design, Setting, and Participants: This retrospective cohort study used data from the National Cancer Database, a hospital-based cancer registry, and the Surveillance, Epidemiology, and End Results Program (SEER), a population-based cancer registry. Population-based race and ethnicity-specific proportions for each cancer site were derived from SEER. Participants included women with an endometrial, ovarian, or cervical cancer diagnosed from 2004 to 2019. Analyses were performed from February 2 to June 14, 2023., Exposure: Race and ethnicity were categorized as American Indian/Alaska Native, Asian, Black, Hispanic (any race), Native Hawaiian/Pacific Islander, White, and other (not defined in the National Cancer Database)., Main Outcomes and Measures: The primary outcomes were the odds of clinical trial enrollment and representation in clinical trials compared with the US population. Multivariable-adjusted logistic regression was used to estimate odds ratios (ORs) and 95% CIs for associations of race and ethnicity with clinical trial enrollment within the National Cancer Database sample. Participation-to-prevalence ratios (PPRs) according to diagnosis period (2004-2011 vs 2012-2019) were calculated by dividing the race and ethnicity-specific percentage of clinical trial participants in the study sample by the percentage of racial and ethnic groups in SEER., Results: Among 562 592 patients with gynecologic cancer (mean [SD] age at diagnosis, 62.9 [11.3] years), 1903 were American Indian/Alaska Native, 18 680 were Asian, 56 421 were Black, 38 145 were Hispanic, 1453 were Native Hawaiian/Pacific Islander, 442 869 were White, and 3121 were other race and ethnicity. Only 548 (<1%) were enrolled in clinical trials. Compared with White women, clinical trial enrollment was lower for Asian (OR, 0.44; 95% CI, 0.25-0.78), Black (OR, 0.70; 95% CI, 0.50-0.99), and Hispanic (OR, 0.53; 95% CI, 0.33-0.83) women. Compared with the US population, White women were adequately or overrepresented for all cancer types (PPRs ≥1.1), Black women were adequately or overrepresented for endometrial and cervical cancers (PPRs ≥1.1) but underrepresented for ovarian cancer (PPR ≤0.6), and Asian and Hispanic women were underrepresented among all 3 cancer types (PPRs ≤0.6)., Conclusions and Relevance: In this cohort of patients with gynecologic cancer, clinical trial enrollment was lower among certain minoritized racial and ethnic groups. Continued efforts are needed to address disparate clinical trial enrollment among underrepresented groups.

Background: The fluctuation or even loss of estrogen level caused by menopause in women, and most gynecological cancers often occur before and after menopause, so the age of menopause may be related to the occurrence of gynecological cancer., Aim: To investigate whether the age at menopause is independently associated with the incidence of gynecological cancers and to analyze the possible influencing factors., Methods: We selected the NHANES public database to conduct the study, and by excluding relevant influencing factors, we finally included 5706 NHANES participants who had full data on age at menopause and the occurrence of gynecologic cancers to analyze the relationship between the amount of age at menopause and gynecologic cancers based on univariate or multifactorial logistic regression analysis. Further, the relationship between age at menopause and the prevalence of different gynecologic cancers was investigated, and changes in the prevalence of different gynecologic cancers by age at menopause subgroups were observed. Finally, other relevant factors affecting the prevalence of gynecologic cancers were further investigated by subgroup analysis as well as subcluster analysis., Results: Univariate logistic regression analysis between age at menopause and gynecologic tumor prevalence revealed a negative association between age at menopause and the prevalence of common gynecologic cancers ovarian and cervical cancer, and after adjusting for the effects of covariates, a higher risk of gynecologic tumors was found with statistically significant differences at earlier age at menopause. The regression results showed a negative association between age at menopause and gynecologic cancer prevalence in cervical and ovarian cancer patients (P<0.01,P<0.01). Cervical cancer (OR: 0.91, 95% CI: 0.87,0.94) and ovarian cancer (OR: 0.90, 95% CI: 0.86, 0.95) were more prevalent among those with younger age at menopause., Conclusion: Age at menopause is negatively associated with the prevalence of cervical and ovarian cancers, and the earlier the age at menopause, the greater the risk of developing gynecological cancers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Cheng, Wang, Sun, Lai, Feng, Liu, Shang, Zhao, Zuo and Lu.)

Objective: To analyze the impact of the early COVID-19 pandemic on the diagnosis and initiation of treatment for patients with gynecologic cancer., Methods: Patients diagnosed with gynecologic cancer in the National Cancer Database during 2017-2020 were included. For the first aim, incidence rate ratios were calculated to compare gynecologic cancer diagnosis in the first year of the COVID-19 pandemic to the three years prior, and factors associated with a reduction in diagnosis were identified. For the second aim, patients who experienced an 8-week delay in cancer treatment were compared to those who did not. Multivariate logistic regression was used to identify factors associated with treatment delay. Propensity score analysis was utilized to compare the rate of cancer treatment delay in patients who were diagnosed with COVID-19 to those who were not., Results: The incidence rate ratio of being diagnosed with gynecologic cancer in 2020 versus 2017-2019 was 0.90 (95%CI 0.90-0.91). Factors associated with increased risk of missed or delayed diagnosis in 2020 included cervical cancer, earlier cancer stage, younger age, lower levels of medical comorbidity, and lack of health insurance. In 2020, factors associated with treatment delay included COVID-19 diagnosis (aOR 1.50, 95%CI 1.35-1.67), in addition to race and ethnicity, insurance type, comorbidity, cancer stage, and primary site. The risk of treatment delay remained significantly elevated in patients diagnosed with COVID-19 after propensity-score matching., Conclusions: Gynecologic cancer diagnosis and timely provision of care were negatively impacted during the first year of the COVID-19 pandemic, with certain subgroups at elevated risk., (Copyright © 2023 Elsevier Inc.

Introduction: Little is known about whether a breast or gynecologic cancer diagnosis increases long-term cardiovascular disease (CVD) risk among Black females. The purpose of this study was to determine whether a breast or gynecologic cancer diagnosis is associated with CVD risk and identify determinants of subsequent CVD risk among Black females with an incident breast or gynecologic cancer diagnosis., Methods: Using the Southern Community Cohort Study data from 2002-2016, this study was designed to analyze CVD incidence among Black females without cancer or CVD at enrollment. Cox proportional hazards regression models with or without covariates were used to explore the relationship between a breast or gynecologic cancer diagnosis and CVD risk among women without cancer as well as without CVD at enrollment (N=11,486). In addition, Cox proportional hazards regression models, excluding those who developed CVD before breast and gynecologic cancer diagnosis and those with other types of cancers, were used to assess determinants of CVD risk among breast and gynecologic cancer survivors., Results: Of 11,486 Black females, 531 developed a breast or gynecological cancer (4.6%) over a median follow-up of 140 months (interquartile range: 123-159 months). Compared to women without cancer, women with a breast or gynecological cancers had greater than 20% higher risk of incident CVD during the follow-up period. Without adjusting for covariates, positive association between CVD risk and breast cancer was observed (hazard ratio (HR) = 1.24; 95% confidence interval (CI) = 1.11 - 1.39; p < 0.001); as well as between CVD risk and a gynecological cancer (HR = 1.23; 95% CI = 1.03 - 1.46; p = 0.021). Yet, after adjusting for covariates, CVD risk was only significantly associated with breast cancer (p = 0.001) but not gynecologic cancer. In cancer case-only analyses, CVD risk was significantly increasing with age (p < 0.05)., Conclusions: Like study populations of predominantly White females, our results suggest that, adjusting for covariates, Black females possess a higher risk of CVD following a breast cancer diagnosis compared to women who did not develop breast cancer. Our results suggest a need for active CVD surveillance in the cancer survivorship phase., (Copyright © 2023. Published by Elsevier Inc.)

Background: The SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) pandemic changed the distribution of healthcare resources, leading in many cases to the suspension of all non-essential treatments and procedures and representing a challenge for medical professionals. The objective of this study was to evaluate whether clinical protocols in gynecologic oncology care were modified as a result of the pandemic and to assess surgeons' perceptions regarding the management of gynecologic cancers"., Methods: Data were collected through an anonymous and voluntary survey sent via email to healthcare professionals in the field of gynecologic oncology in Spain., Results: A total of 75 gynecologic oncologists completed the online survey. Of these, 93.2% (69) reported working in public hospitals and 62.5% (45) in tertiary care hospitals. 97.3% (71) were affiliated with hospitals treating patients infected with SARS-CoV-2. 85.1% (63) of the respondents expressed concern about the SARS-CoV-2 pandemic and 52.1% (38) indicated that the pandemic impacted the diagnostic and therapeutic quality of care for oncology patients. SARS-CoV-2 nasopharyngeal swab PCR (Polymerase Chain Reaction) testing was always performed before surgical interventions by 97.3% (71), being considered a best practice in triage by 94.4% (68). 87.5% (63) reported no change in the type of surgical approach during the pandemic. 62.5% (45) experienced limitations in accessing special personal protective equipment for SARS-CoV-2. An impact on the follow-up of patients with gynecologic cancers due to the pandemic was reported by 70.4% (50)., Conclusions: Most of the Spanish gynecologic oncologists who responded to our survey reported that the SARS-CoV-2 pandemic had affected their clinical practice. The primary measures implemented were an increase in telemedicine, restricting outpatient visits to high-risk or symptomatic patients and the use of SARS-CoV-2 screening prior to surgery. No major changes in the surgical approach or management of the treatment of ovarian, endometrial or cervical cancer during the pandemic were reported., (© 2023.

Objective: To analyze research publication trends in high-impact factor journals, comparing gynecologic cancers with other cancers from 2000 to 2018., Methods: Abstracts from the 55 journals with the highest impact factors, as measured by Clarivate, from 2000 to 2018 were extracted from PubMed. We developed an algorithm to search the title of the abstract to determine whether the abstract was about cancer and to identify the cancer type. The algorithm was validated against the gold standard of human review in 1,143 abstracts. Article proportion was compared with site-specific incidence, mortality, and lethality from the National Cancer Institute's Surveillance, Epidemiology and End Results database using scatterplots and nonparametric Wilcoxon signed-rank test., Results: We identified 128,377 articles; 31,045 (24.1%) were about cancer and 1,189 (3.8%) were about gynecologic cancers. Gynecologic cancers (ovarian, cervical, and uterine) were all poorly represented in high-impact factor journals compared with their incidence, mortality, and lethality. Ovarian, uterine, and cervical cancers ranked in the bottom half of Article-to-Lethality scores ( P <.01 for all comparisons). Analyses of the trends for gynecologic cancers over the past 18 years showed no change over time in Article-to-Lethality scores. Comparison of rankings by lethality with rankings by funding indicates relative underfunding of the gynecologic cancers., Conclusion: Research publications in high-impact factor journals by cancer site are not proportionate with individual cancer burden on society. Gynecologic cancers are significantly underrepresented in research publications relative to their disease burden, indicating a disparity that persists over the past 18 years. Relative underfunding of gynecologic cancers likely contributes to this publication gap., Competing Interests: Financial Disclosure Emma Barber reports receiving payment from Merck.

Objective: Women are experiencing growing rates of incarceration at twice the pace of that for men. Additionally, one-third will be older than 55 years of age by the end of the decade. Women who are incarcerated experience a higher prevalence of gynecologic malignancies and present with higher stage disease, which may be contributing to the greater mortality from cancer than the age-adjusted US population. Limited access to guideline-recommended screening and prevention and resource limitations across correctional facilities may result in gynecologic cancer disparities. Reasons for delayed gynecologic cancer care in prisons remain underexplored. Therefore, we sought to identify contributors to delayed gynecologic cancer care among women experiencing incarceration., Methods: Women at a single tertiary center in the Southeastern U.S. who were incarcerated and were diagnosed with a gynecologic cancer during 2014-2021 were identified in the electronic medical record. Note text was extracted and contributors to delay were identified and categorized using the RADaR method. Descriptive statistics were used to assess quantitative data., Results: 14 patients were identified with a total of 14,879 text excerpts. Data reduction was performed to identify excerpts that were relevant to the central research question resulting in 175 relevant note excerpts. Delays prior to the tertiary care visit included patient and institutional contributors. Delays during transition from the tertiary center to prison included discharge planning and loss to follow-up during/after incarceration. Transportation, authorization, and restraints were concrete contributors. Abstract contributors included communication, and the patient's emotional experience., Conclusions: We identify myriad contributors to delayed or fractured gynecologic cancer care in women experiencing incarceration. The impact of these issues warrants further study and intervention to improve care., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier Inc.

Objective: Early palliative care (PC) is associated with improved patient quality of life, less aggressive end-of-life care, and prolonged survival. We evaluated patterns of PC delivery in gynecologic oncology., Methods: We conducted a population-based, retrospective cohort study of gynecologic cancer decedents in Ontario from 2006 to 2018 using linked administrative health care data., Results: The cohort included 16,237 decedents; 51.1% died of ovarian cancer, 30.3% uterine cancer, 12.1% cervical cancer, and 6.5% vulvar/vaginal cancers. Palliative care was most often delivered in the hospital inpatient setting in 81%, and 53% received specialist PC. PC was first received during hospital admission in 53%, and by outpatient physician care in only 23%. Palliative care was initiated a median 193 days prior to death, with the lowest two quintiles initiating care ≤70 days before death. The average user of PC resources (third quintile) received 68 days of PC. While cumulative use of community PC gradually increased over the final year of life, institutional palliative care use exponentially rose from 12 weeks until death. On multivariable analyses, predictors of initiating palliative care during a hospital admission included age ≥70 years at death, ≤3 month cancer survival, having cervical or uterine cancer, not having a primary care provider, or being in the lowest 3 income quintiles., Conclusion: Most palliative care is initiated and delivered during hospital admission, and is initiated late in a significant proportion. Strategies to increase access to anticipatory and integrated palliative care may improve the quality of the disease course and the end of life., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2023 Elsevier Inc.

Objective: To study the impact of the COVID-19 pandemic and consequent lockdown on the number of diagnoses of gynaecological malignancies in the Netherlands., Methods: We performed a retrospective cohort study using data from the Netherlands Cancer Registry (NCR) on women of 18 years and older diagnosed with invasive endometrial, ovarian, cervical or vulvar cancer in the period 2017-2021. Analyses were stratified for age, socioeconomical status (SES) and region., Results: The incidence rate of gynaecological cancer was 67/100.000 (n = 4832) before (2017-2019) and 68/100.000 (n = 4833) during (2020) the COVID-19 pandemic. Comparing the number of diagnoses of the two periods for the four types of cancer separately showed no significant difference. During the first wave of COVID-19 (March-June 2020), a clear decrease in number of gynaecological cancer diagnoses was visible (20-34 %). Subsequently, large increases in number of diagnoses were visible (11-29 %). No significant differences in incidence were found between different age groups, SES and regions. In 2021 an increase of 5.9 % in number of diagnoses was seen., Conclusion: In the Netherlands, a clear drop in number of diagnoses was visible for all four types of gynaecological cancers during the first wave, with a subsequent increase in number of diagnoses in the second part of 2020 and in 2021. No differences between SES groups were found. This illustrates good organisation of and access to health care in the Netherlands., Competing Interests: Declaration of Competing Interest Prof. dr.

Background: Maintaining a healthy lifestyle is an important factor in promoting positive outcomes for gynecologic cancer survivors., Methods: We examined preventive behaviors among gynecologic cancer survivors (n = 1824) and persons without a history of cancer in a cross-sectional analysis, using data from the 2020 Behavioral Risk Factor Surveillance System survey (BRFSS). BRFSS is a cross-sectional telephone-based survey of U.S. residents 18 years of age and older, which collects information about health-related factors and use of preventive services., Results: The prevalence rates of colorectal cancer screening were respectively 7.9 (95% CI: 4.0-11.9) and 15.0 (95% CI: 4.0-11.9) %-points higher among gynecologic and other cancer survivors compared to that of 65.2% among those without any history of cancer. However, no differences were observed in breast cancer screening between gynecologic cancer survivors (78.5%) and respondents without any history of cancer (78.7%). Coverage of influenza vaccination among gynecologic cancer survivors were 4.0 (95% CI: 0.3-7.6) %-points higher than that of the no cancer group, but 11.6 (95% CI: 7.6-15.6) %-points lower than that of the other cancer group. Pneumonia vaccination rate among gynecologic cancer survivors, however, was not statistically different than that of other cancer survivors and respondents with no history of cancer. When examining modifiable risk behaviors, the prevalence of smoking among gynecologic cancer survivors was 12.8 (95% CI: 9.5-16.0) and 14.2 (95% CI: 10.8-17.7) %-points higher than smoking prevalence among other cancer survivors and respondents without any history of cancer. The rate differentials were even higher in rural areas, 17.4 (95% CI: 7.2-27.6) and 18.4 (95% CI: 7.4-29.4) %-points respectively. There were no differences in the prevalence of heavy drinking across the groups. Lastly, gynecologic and other cancer survivors were less likely to be physically active (Δ = -12.3, 95% CI: -15.8 to -8.8 and Δ = -6.9, 95% CI: -8.5 to -5.3, respectively) than those without any history of cancer., Conclusion: Smoking prevalence among gynecologic cancer survivors is alarmingly high. Intervention studies are needed to identify effective ways to assist gynecologic cancer survivors to quit smoking and refrain from hazardous alcohol consumption. In addition, women with gynecologic malignancies should made aware of the importance of physical activity., (© 2023 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

The article discusses various pathophysiological conditions and processes that lead to the development of tumors in diabetes mellitus. These include obesity, hyperglycemia, hyperinsulinemia, inflammation, and oxidative stress. The data of epidemiological studies are given, in which it was found that diabetes mellitus (both type 1 and type 2) increases the risk of developing the female reproductive system tumors, such as ovarian cancer, endometrial cancer, while for cervical cancer, vaginal cancer and vulvar cancer, such a relationship has not been clearly identified.
