Sociodemographic, clinical characteristics, and treatment patterns of endometrial cancer cases in Puerto Rico during the period 2009 to 2015: A retrospective study.

BACKGROUND: Over the past decades, the rising incidence rates of endometrial cancer have made it a significant public health concern for women worldwide. Treatment strategies for endometrial cancer vary based on several factors such as stage, histology, the patient's overall health, and preferences. However, limited amount of research on treatment patterns and potential correlations with sociodemographic characteristics among Hispanics is available. This study analyzes the treatment patterns for patients diagnosed with endometrial cancer in Puerto Rico. METHODS: A secondary database analysis was performed on endometrial cancer cases reported to the Puerto Rico Central Cancer Registry-Health Insurance Linkage Database from 2009 to 2015 (n = 2,488). The study population's sociodemographic and clinical characteristics were described, along with an overview of the therapy options provided to patients receiving care on the island. Logistic regression models were used to evaluate the association of sociodemographic/clinical characteristics with treatment patterns stratified by risk of recurrence. RESULTS: In our cohort, most patients were insured through Medicaid and had a median age of 60 years. Almost 90% of patients received surgery as the first course of treatment. Surgery alone was the most common treatment for low-risk patients (80.2%). High-risk patients were more likely to receive surgery with radiotherapy and chemotherapy (24.4%). Patients with Medicare insurance were five times (HR: 4.84; 95% CI: 2.45-9.58; p < 0.001) more likely to receive surgery when compared with patients insured with Medicaid. In contrast, those with private insurance were twice as likely to receive surgery (HR: 2.38; 95% CI: 1.40-4.04; p = 0.001) when compared to those with Medicaid. CONCLUSION: These findings provide insight into the treatment patterns for endometrial cancer in Puerto Rico and highlight the importance of considering factors such as disease risk when making treatment decisions. Addressing these gaps in treatment patterns can contribute to effective management of endometrial cancer.

Reproductive and Oncologic Outcomes in Young Women with Stage IA and Grade 2 Endometrial Carcinoma Undergoing Fertility-Sparing Treatment: A Systematic Review.

BACKGROUND: Endometrial cancer (EC) is the most common gynecological malignancy in both Europe and the USA. Approximately 3-5% of cases occur in women of reproductive age. Fertility-sparing treatment (FST) options are available, but very limited evidence regarding grade 2 (G2) ECs exists in the current literature. This systematic review aimed to comprehensively evaluate reproductive and oncologic outcomes among young women diagnosed with stage IA or G2EC disease who underwent FST. METHODS: A comprehensive search of the literature was carried out on the following databases: MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), the Health Technology Assessment Database, and Web of Science. Only original studies that reported the oncologic and reproductive outcomes of patients with stage IA and G2EC tumors who underwent FST were considered eligible for inclusion in this systematic review (CRD42023484892). Studies describing only the FST for endometrial hyperplasia or G1 EC were excluded. RESULTS: Twenty-two papers that met the abovementioned inclusion criteria were included in the present systematic review. Preliminary analysis suggested encouraging oncologic and reproductive outcomes after FST. CONCLUSIONS: The FST approach may represent a feasible and safe option for women of childbearing age diagnosed with G2EC. Despite these promising findings, cautious interpretation is warranted due to inherent limitations, including heterogeneity in study designs and potential biases. Further research with standardized methodologies and larger sample sizes is imperative for obtaining more robust conclusions.

Psychometric validation of the Functional Assessment of Cancer Therapy-Endometrial among endometrial cancer patients.

OBJECTIVE: To evaluate a psychometric validation of the endometrial cancer subscales (EnCS) in the Functional Assessment of Cancer Therapy-Endometrial (FACT-EN) among patients with endometrial cancer. METHODS: This cross-sectional study was conducted at a tertiary university-based hospital in South Korea between April and October 2022. Participants completed a survey questionnaire that included the FACT-EN. Exploratory and confirmatory factor analyses (EFA, CFA) and the reliability were measured using the intraclass correlation coefficient (ICC) under a two-way mixed model. Pearson's correlations were used to evaluate the validity. We also tested known-group validity. RESULTS: In total, 240 patients with endometrial cancer participated in the survey. In EFA, we found EnCS included four domains. In CFA, four-factor solution model was good: CFI = 0.659; SRMR = 0.066, and RMSEA = 0.073. The mean (SD) of total score of FACT-EN was 122.84 (23.58). The floor and ceiling effects were 0.4% and 0.4%, respectively. Cronbach's α coefficients for the five scales of the EnCS ranged from 0.78 to 0.91. The ICC of EnCS was 0.76. The convergent and discriminant validity of EnCS was acceptable. In the group analysis, older age and lower ECOG performance scores were associated with higher EnCS scores. The stomach and vaginal domains in EnCS were higher in patients who had completed treatment for more than 1 year compared to those who were still undergoing treatment. CONCLUSIONS: FACT-EN has demonstrated its validity as an assessment tool with significant implications for capturing various symptoms in patients with endometrial cancer.

Cost-utility analysis of a supervised exercise intervention for women with early-stage endometrial cancer.

PURPOSE: Cardiovascular disease (CVD) is the leading cause of death after treatment for endometrial cancer (EC). There is clinical evidence that exercise significantly reduces the risks of CVD and cancer recurrence in this population; however, it is unclear whether there is value for money in integrating exercise into cancer recovery care for women treated for EC. This paper assesses the long-term cost-effectiveness of a 12-week supervised exercise intervention, as compared with standard care, for women diagnosed with early-stage EC. METHOD: A cost-utility analysis was conducted from the Australian health system perspective for a time horizon of 5 years. A Markov cohort model was designed with six mutually exclusive health states: (i) no CVD, (ii) post-stroke, (iii) post-coronary heart disease (CHD), (iv) post-heart failure, (v) post-cancer recurrence, and (vi) death. The model was populated using the best available evidence. Costs and quality-adjusted life years (QALYs) were discounted at 5% annual rate. Uncertainty in the results was explored using one-way and probabilistic sensitivity analyses (PSA). RESULT: The incremental cost of supervised exercise versus standard care was AUD $358, and the incremental QALY was 0.0789, resulting in an incremental cost-effectiveness ratio (ICER) of AUD $5184 per QALY gained. The likelihood that the supervised exercise intervention was cost-effective at a willingness-to-pay threshold of AUD $50,000 per QALY was 99.5%. CONCLUSION: This is the first economic evaluation of exercise after treatment for EC. The results suggest that exercise is cost-effective for Australian EC survivors. Given the compelling evidence, efforts could now focus on the implementation of exercise as part of cancer recovery care in Australia.

Completeness and selection bias of a Belgian multidisciplinary, registration-based study on the EFFectiveness and quality of Endometrial Cancer Treatment (EFFECT).

BACKGROUND: With the aim of obtaining more uniformity and quality in the treatment of corpus uteri cancer in Belgium, the EFFECT project has prospectively collected detailed information on the real-world clinical care offered to 4063 Belgian women with primary corpus uteri cancer. However, as data was collected on a voluntary basis, data may be incomplete and biased. Therefore, this study aimed to assess the completeness and potential selection bias of the EFFECT database. METHODS: Five databases were deterministically coupled by use of the patient's national social security number. Participation bias was assessed by identifying characteristics associated with hospital participation in EFFECT, if any. Registration bias was assessed by identifying patient, tumor and treatment characteristics associated with patient registration by participating hospitals, if any. Uni- and multivariable logistic regression were applied. RESULTS: EFFECT covers 56% of all Belgian women diagnosed with primary corpus uteri cancer between 2012 and 2016. These women were registered by 54% of hospitals, which submitted a median of 86% of their patients. Participation of hospitals was found to be biased: low-volume and Walloon-region centers were less likely to participate. Registration of patients by participating hospitals was found to be biased: patients with a less favorable risk profile, with missing data for several clinical-pathological risk factors, that did not undergo curative surgery, and were not discussed in a multidisciplinary tumor board were less likely to be registered. CONCLUSIONS: Due to its voluntary nature, the EFFECT database suffers from a selection bias, both in terms of the hospitals choosing to participate and the patients being included by participating institutions. This study, therefore, highlights the importance of assessing the selection bias that may be present in any study that voluntarily collects clinical data not otherwise routinely collected. Nevertheless, the EFFECT database covers detailed information on the real-world clinical care offered to 56% of all Belgian women diagnosed with corpus uteri cancer between 2012 and 2016, and may therefore act as a powerful tool for measuring and improving the quality of corpus uteri cancer care in Belgium.

Variation in practice in endometrial cancer and potential for improved care and equity through molecular classification.

OBJECTIVES: We measured the variation in practice across all aspects of endometrial cancer (EC) management and assessed the potential impact of implementation of molecular classification. METHODS: Centers from across Canada provided representative tumor samples and clinical data, including preoperative workup, operative management, hereditary cancer program (HCP) referrals, adjuvant therapy, surveillance and outcomes, for all EC patients diagnosed in 2016. Tumors were classified into the four ProMisE molecular subtypes. RESULTS: A total of 1336 fully evaluable EC patients were identified from 10 tertiary cancer centers (TC; n = 1022) and 19 community centers (CC; n = 314). Variation of surgical practice across TCs was profound (14-100%) for lymphadenectomy (LND) (mean 57% Gr1/2, 82% Gr3) and omental sampling (20% Gr1/2, 79% Gr3). Preoperative CT scans were inconsistently obtained (mean 32% Gr1/2, 51% Gr3) and use of adjuvant chemo or chemoRT in high risk EC ranged from 0-55% and 64-100%, respectively. Molecular subtyping was performed retrospectively and identified 6% POLEmut, 28% MMRd, 48% NSMP and 18% p53abn ECs, and was significantly associated with survival. Within patients retrospectively diagnosed with MMRd EC only 22% had been referred to HCP. Of patients with p53abn EC, LND and omental sampling was not performed in 21% and 23% respectively, and 41% received no chemotherapy. Comparison of management in 2016 with current 2020 ESGO/ESTRO/ESP guidelines identified at least 26 and 95 patients that would have been directed to less or more adjuvant therapy, respectively (10% of cohort). CONCLUSION: Molecular classification has the potential to mitigate the profound variation in practice demonstrated in current EC care, enabling reproducible risk assessment, guiding treatment and reducing health care disparities.

Treatment patterns and economic burden among newly diagnosed cervical and endometrial cancer patients.

Aim: This study evaluated treatment patterns, healthcare resource use and healthcare costs among newly diagnosed US patients with cervical or endometrial cancer. Materials & methods: The authors identified patients diagnosed between 2015 and 2018, described them by line of therapy (LOT), then summarized all-cause per patient per month healthcare resource use and healthcare costs per LOT. Results: Among 1004 patients with cervical cancer and 2006 patients with endometrial cancer, 65.2 and 71.4%, respectively, received at least LOT1. Common treatment modalities in LOT1 were surgery (cervical, 58.0%; endometrial, 92.6%), radiation therapy (cervical, 49.8%; 24.7%) and systemic therapy (cervical, 53.3%; endometrial, 26.1%). Mean per patient per month costs per LOT were pre-treatment (cervical, US$17,210; endometrial, US$14,601), LOT1 (cervical, US$10,929; endometrial, US$6859), LOT2 (cervical, US$15,183; endometrial, US$10,649) and LOT3+ (cervical, US$19,681; endometrial, US$9206). Conclusion: Overall, newly diagnosed patients with cervical or endometrial cancer received guideline-recommended treatment. Outpatient visits mainly drove healthcare costs across LOTs.

Racial-Ethnic and Socioeconomic Disparities in Guideline-Adherent Treatment for Endometrial Cancer.

OBJECTIVE: To evaluate the association of race-ethnicity and neighborhood socioeconomic status with adherence to National Comprehensive Cancer Network guidelines for endometrial carcinoma. METHODS: Data are from the SEER (Surveillance, Epidemiology, and End Results) cancer registry of women diagnosed with endometrial carcinoma for the years 2006-2015. The sample included 83,883 women after inclusion and exclusion criteria were applied. Descriptive statistics, bivariate analyses, univariate, and multivariate logistic regression models were performed to evaluate the association between race-ethnicity and neighborhood socioeconomic status with adherence to treatment guidelines. RESULTS: After controlling for demographic and clinical covariates, Black (odds ratio [OR] 0.89, P<.001), Latina (OR .92, P<.001), and American Indian or Alaska Native (OR 0.82, P=.034) women had lower odds of receiving adherent treatment and Asian (OR 1.14, P<.001) and Native Hawaiian or Pacific Islander (OR 1.19 P=.012) women had higher odds of receiving adherent treatment compared with White women. After controlling for covariates, there was a gradient by neighborhood socioeconomic status: women in the high-middle (OR 0.89, P<.001), middle (OR 0.84, P<.001), low-middle (OR 0.80, P<.001), and lowest (OR 0.73, P<.001) neighborhood socioeconomic status categories had lower odds of receiving adherent treatment than the those in the highest neighborhood socioeconomic status group. CONCLUSIONS: Findings from this study suggest there are racial-ethnic and neighborhood socioeconomic disparities in National Comprehensive Cancer Network treatment adherence for endometrial cancer. Standard treatment therapies should not differ based on sociodemographics. Interventions are needed to ensure that equitable cancer treatment practices are available for all individuals, regardless of racial-ethnic or socioeconomic background.

Employment disruption following the diagnosis of endometrial cancer.

BACKGROUND: Oncologic treatment has been associated with unemployment. As endometrial cancer is highly curable, it is important to assess whether patients experience employment disruption after treatment. We evaluated the frequency of employment change following endometrial cancer diagnosis and assessed factors associated with it. METHODS: A cohort of patients 18-63 years-old who were diagnosed with endometrial cancer (January 2009-December 2017) were identified in the Truven MarketScan database, an insurance claims database of commercially insured patients in the United States. All patients who were working full- or part-time at diagnosis were included and all employment changes during the year following diagnosis were identified. Clinical information, including use of chemotherapy and radiation, were identified using Common Procedural Terminology codes, and International Statistical Classification of Diseases codes. Cox proportional hazards models incorporating measured covariates were used to evaluate the impact of treatment and demographic variables on change in employment status. RESULTS: A total of 4381 women diagnosed with endometrial cancer who held a full-time or part-time job 12 months prior to diagnosis were identified. Median age at diagnosis was 55 and a minority of patients received adjuvant therapy; 7.9% received chemotherapy, 4.9% received external-beam radiation therapy, and 4.1% received chemoradiation. While most women continued to work following diagnosis, 21.7% (950) experienced a change in employment status. The majority (97.7%) of patients had a full-time job prior to diagnosis. In a multivariable analysis controlling for age, region of residence, comorbidities, insurance plan type and presence of adverse events, chemoradiation recipients were 34% more likely to experience an employment change (HR 1.34, 95% CI 1.01-1.78), compared to those who only underwent surgery. CONCLUSION: Approximately 22% of women with employer-subsidized health insurance experienced a change in employment status following the diagnosis of endometrial cancer, an often-curable disease. Chemoradiation was an independent predictor of change in employment.

Toxicity after adjuvant therapy for stage III uterine cancer.

OBJECTIVE: The optimal adjuvant therapy for stage III endometrial cancer is unknown. Studies have suggested that combination therapy with chemotherapy and radiation is associated with improved survival. We examined early and late-term toxicities associated with chemotherapy (CT), external beam radiotherapy (RT), or combination chemoradiotherapy for stage III uterine cancer. METHODS: The SEER-Medicare database was used to identify women age ≥ 65 years with stage III uterine cancer who received adjuvant CT, RT, or chemoradiotherapy from 2000 to 2015. The associations between therapy and early and late-term toxicities identified with billing claims, hospitalizations and emergency department visits were examined using multivariable regression models. RESULTS: A total of 2185 patients were identified including 574 (26.3%) who received CT, 636 (29.1%) who received RT, and 975 (44.6%) who received chemoradiotherapy. The proportion of patients receiving chemoradiotherapy or CT increased over time. During the first 6 and 12 months of adjuvant therapy, RT was associated with a lower risk of early-term toxicity compared to chemoradiotherapy (aRR = 0.59, 95%CI 0.49-0.70 and aRR = 0.76, 95%CI 0.67-0.86, respectively) while CT shared a similar risk of early toxicities as chemoradiotherapy. CT and RT shared a similar risk of late-term toxicities compared to chemoradiotherapy. CT and RT alone were associated with a higher hazard for overall mortality than chemoradiotherapy (aHR = 1.27, 95% CI 1.10-1.47 and aHR = 1.25, 95% CI 1.08-1.44, respectively). CONCLUSION: Chemoradiotherapy is associated with lower mortality compared to single modality therapy and has a similar risk of early and late term toxicities compared to CT, though higher risk of early toxicities compared to RT.

ESMO management and treatment adapted recommendations in the COVID-19 era: gynaecological malignancies.

The rapid spread of severe acute respiratory syndrome coronavirus 2 infection and its related disease (COVID-19) has required an immediate and coordinate healthcare response to face the worldwide emergency and define strategies to maintain the continuum of care for the non-COVID-19 diseases while protecting patients and healthcare providers. The dimension of the COVID-19 pandemic poses an unprecedented risk especially for the more vulnerable populations. To manage patients with cancer adequately, maintaining the highest quality of care, a definition of value-based priorities is necessary to define which interventions can be safely postponed without affecting patients' outcome. The European Society for Medical Oncology (ESMO) has endorsed a tiered approach across three different levels of priority (high, medium, low) incorporating information on the value-based prioritisation and clinical cogency of the interventions that can be applied for different disease sites. Patients with gynaecological cancer are at particular risk of COVID-19 complications because of their age and prevalence of comorbidities. The definition of priority level should be based on tumour stage and histology, cancer-related symptoms or complications, aim (curative vs palliative) and magnitude of benefit of the oncological intervention, patients' general condition and preferences. The decision-making process always needs to consider the disease-specific national and international guidelines and the local healthcare system and social resources, and a changing situation in relation to COVID-19 infection. These recommendations aim to provide guidance for the definition of deferrable and undeferrable interventions during the COVID-19 pandemic for ovarian, endometrial and cervical cancers within the context of the ESMO Clinical Practice Guidelines.

Effect of regionalization of endometrial cancer care on site of care and patient travel.

BACKGROUND: Complex oncologic surgeries, including those for endometrial cancer, increasingly have been concentrated to greater-volume centers, owing to previous research that has demonstrated associations between greater surgical volume and improved outcomes. There is a potential for concentration of care to have unwanted consequences, including cost burden, delayed treatment, patient dissatisfaction, and possibly worse clinical outcomes, especially for more vulnerable populations. OBJECTIVE: To describe changes in site of care for patients with endometrial cancer in New York State and to determine whether the distance women traveled for hysterectomy has changed over time. STUDY DESIGN: We used the New York Statewide Planning and Research Cooperative System to identify women with endometrial cancer who underwent hysterectomy from 2000 to 2014. Demographic and clinical data as well as hospital data were collected. Trends in travel distance (straight-line distance) were analyzed within all hospital referral regions and differences in travel distance over times and across sociodemographic characteristics analyzed. RESULTS: We identified 41,179 subjects. The number of hospitals and surgeons performing hysterectomy decreased across all hospital referral regions over time. The decline in the number of hospitals caring for women with endometrial cancer ranged from -16.7% in Syracuse (12 to 10 hospitals) to -76.5% in Rochester (17 to 4 hospitals). Similarly, the percentage of surgeons within a given hospital referral region operating on women declined from -45.2% in Buffalo (84-46 surgeons) to -77.8% in Albany (72 to 16 surgeons). The median distance to the index hospital for patients increased in all Hospital Referral Regions. For residents in Binghamton, median travel distance increased by 46.9 miles (95% confidence interval, 33.8-60.0) whereas distance increased in Elmira by 19.7 miles (95% confidence interval, 7.3-32.1) and by 12.4 miles (95% confidence interval, 6.4-18.4) in Albany. For residents of Binghamton and Albany, there was a greater than 100% increase in distance traveled over the 15-year time period, with increases of 551.8% (46.9 miles; 95% confidence interval, 33.8-60.0 miles) and 102.5% (12.4 miles; 95% confidence interval, 6.4-18.4 miles), respectively. Travel distance increased for all races and regardless of insurance status but was greatest for white patients and those with private insurance (P<.0001 for both). CONCLUSION: The number of surgeons and hospitals caring for women with endometrial cancer in New York State has decreased, whereas the distance that patients travel to receive care has increased over time.

Effects of hormone therapy on recurrence in endometrial cancer survivors: a nationwide study using the Korean Health Insurance Review and Assessment Service database.

OBJECTIVE: The aim of this study was to verify the effects of hormone therapy (HT) on recurrence in endometrial cancer (EC) survivors using the Korean Health Insurance Review and Assessment Service (HIRA) database. METHODS: Using the HIRA claims database, we identified all Korean women who were newly diagnosed with EC and underwent surgical staging between 2010 and 2013. Patient characteristics such as age, HT exposure, lymphadenectomy, and adjuvant therapy were evaluated. Cox proportional hazards models were used to estimate the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the recurrence of EC. RESULTS: The mean follow-up time of all 5,667 eligible patients was 47.5 months. Of these, 847 (14.9%) received HT. Recurrence was seen in 446 (7.8%) patients. Univariate analysis revealed an increased recurrence rate in patients older than 50 years (HR=2.05; 95% CI=1.62-2.63), patients with high-risk EC (HR=24.51; 95% CI=18.63-32.35), and patients who underwent lymphadenectomy (HR=1.52; 95% CI=1.21-2.03), and a reduced recurrence rate in patients who received HT (HR=0.62; 95% CI=0.46-0.83). Multivariate analysis confirmed the significant increase in recurrence in patients older than 50 years (HR=1.47; 95% CI=1.14-1.89) and in patients with high-risk EC (HR=23.90; 95% CI=18.12-31.51). HT did not increase the recurrence rate of EC (HR=0.81; 95% CI=0.31-2.10). CONCLUSION: This study demonstrates that HT does not increase disease recurrence in EC survivors, despite lack of data that could affect the outcome.

[Circulating tumor DNA assessment for gynaecological cancers management]. / Apports de l'ADN tumoral circulant dans la compréhension et la prise en charge des carcinomes d'origine gynécologique.

Gynaecological cancers are frequent, with more than 16,000 cases per year in France for 6500 deaths. Few improvements in diagnostic methods, prognostic tools, and therapeutic strategies have occurred in the last two decades. Tumour genomic analyses from, at least in part, the Cancer Genome Atlas have identified some of the molecular alterations involved in gynaecological tumours growth and spreading. However, these data remain incomplete and have not led to dramatic changes in the clinical management of our patients. Moreover, they require invasive samples that are not suitable to objectives like screening/early diagnosis, assessment of treatment efficacy, monitoring of residual disease or early diagnosis of relapse. In the last years, the analysis of circulating tumour biomarkers (also called "liquid biopsies") based on tumour cells (circulating tumour cells) or tumour nucleotides (circulating DNA or RNA) has been massively explored through various indications, platforms, objectives; data related to circulating tumour DNA being the most important in terms of number of publications and interest for clinical practice. This review aims to describe the methods of analysis as well as the observations from the analysis of circulating tumour DNA in gynaecological tumours, from screening/early diagnosis to the adaptation of treatment for advanced stages, through choice of treatments and monitoring of subclinical disease.

National patterns of care and cancer-specific outcomes of adjuvant treatment in patients with serous and clear cell endometrial carcinoma.

OBJECTIVES: To investigate outcomes of adjuvant therapy for serous and clear cell endometrial carcinoma, as prior studies are limited by sample size and/or patient heterogeneity. National guidelines permit substantial variations in treatment, suggesting the need for additional data. METHODS: Patients with FIGO stages I-III serous or clear cell uterine carcinoma who underwent at least total hysterectomy were identified in SEER-Medicare. Adjuvant external beam radiation, brachytherapy, and chemotherapy were determined using SEER fields and Medicare claims. The primary outcome was death from endometrial cancer (cancer-specific mortality [CSM]) evaluated using Gray's test (univariable analysis, UVA) and Fine-Gray regression (multivariable analysis, MVA). RESULTS: A total of 1789 patients (1437 serous, 352 clear cell) were identified. In stages I-II patients (n = 1188), brachytherapy was significant for survival in UVA (P = 0.03) and MVA (P = 0.02). Additionally, in the subset with serous histology (n = 947), chemotherapy was also significant in UVA (P = 0.002) and approached significance in MVA (P = 0.05). The 4-year CSM for stages I-II serous cancers was 25% without brachytherapy or chemotherapy, 15% with one, and 9% with both (P ≤ 0.05 for all pairwise comparisons). In stage III patients (n = 601), chemotherapy was significant in UVA (P = 0.002) and MVA (P = 0.006). Most (81%) patients underwent lymph node dissection, which predicted lower CSM in stage III (P = 0.001) but not stages I-II patients. CONCLUSIONS: Our results suggest brachytherapy benefits stages I-II serous/clear cell cancers, chemotherapy benefits stage III serous/clear cell cancers, and both chemotherapy and brachytherapy benefit stages I-II serous cancers.

The prevalence of Lynch syndrome in women with endometrial cancer: a systematic review protocol.

BACKGROUND: Lynch syndrome is the most common inherited cancer syndrome, which predisposes individuals to a number of different cancers, principally colorectal and endometrial cancer. The early diagnosis of Lynch syndrome enables colorectal surveillance, which has been shown to save lives through the detection and removal of premalignant polyps and earlier detection of invasive disease. Endometrial cancer, which is often the sentinel cancer in women, provides an opportunity to diagnose Lynch syndrome and thus enable colorectal surveillance as well as the cascade testing for Lynch syndrome in other family members. These potential benefits have led to a call for the universal screening of women with endometrial cancer for Lynch syndrome, a practice that is now commonplace in colorectal cancer. Healthcare providers and clinicians are however restricted by insufficient knowledge about the prevalence of Lynch syndrome in women with endometrial cancer, with estimates varying as widely as 1-10%. The aim of this study is to perform a systematic review with a meta-analysis of the current literature base in order to estimate the prevalence of Lynch syndrome among women with endometrial cancer to inform this discussion. METHODS: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Methodology Register, NHS Health and Technology Assessment Database and the Web of Science will be systematically searched for relevant studies via the Ovid platform. Two authors will review the titles and abstracts independently, with discrepancy settled by a third author. Data extraction will be completed to record demographic, pathological and clinical data, as well as the diagnostic methods used for estimating the prevalence of Lynch syndrome in women with endometrial cancer. Bias will be assessed and recorded using the Newcastle-Ottawa Scale and that of the International Cochrane Collaboration. Dependent on the heterogeneity of the data, we aim to produce a cumulative incidence in addition to subgroup analyses as to investigate secondary outcomes. DISCUSSION: The aim of this systematic review is to provide a robust estimate of the prevalence of Lynch syndrome in women with endometrial cancer. This will enable resource allocation and decision-making regarding the appropriateness of screening all women, or certain women, with endometrial cancer for Lynch syndrome. Such a policy could enable the earlier diagnosis of Lynch syndrome in women and, through the application of colorectal cancer surveillance, improve their survival outcomes. SYSTEMATIC REVIEW REGISTRATION: This systematic review has been registered on PROSPERO (ref CRD42017081707 ).

ENdometrial cancer SURvivors' follow-up carE (ENSURE): Less is more? Evaluating patient satisfaction and cost-effectiveness of a reduced follow-up schedule: study protocol of a randomized controlled trial.

BACKGROUND: It has often been hypothesized that the frequency of follow-up visits for patients with early-stage endometrial cancer could be decreased. However, studies evaluating effects of a reduced follow-up schedule among this patient group are lacking. The aim of this study is to assess patient satisfaction and cost-effectiveness of a less frequent follow-up schedule compared to the schedule according to the Dutch guideline. METHODS: In this multicenter randomized controlled trial, patients diagnosed in the Netherlands with stage 1A and 1B low-risk endometrial cancer, for whom adjuvant radiotherapy is not indicated (n = 282), are randomized. Patients allocated to the intervention group receive four follow-up visits during three years. Patients allocated to the control group receive 10-13 follow-up visits during five years, according to the Dutch guideline. Patients are asked to fill out a questionnaire at baseline and after 6, 12, 36, and 60 months. Primary outcomes include patient satisfaction with follow-up care and cost-effectiveness. Secondary outcomes include healthcare use, adherence to schedule, health-related quality of life, fear of recurrence, anxiety and depression, information provision, recurrence, and survival. Linear regression analyses will be used to assess differences in patient satisfaction with follow-up care between intervention and control group. DISCUSSION: We anticipate that patients in the intervention arm have a similar satisfaction with follow-up care and overall outcomes, but lower healthcare use and costs than patients in the control arm. No differences are expected in quality-adjusted life-years and satisfaction, but the reduced schedule is expected to be cost-saving when implemented in the Netherlands.

Society of Gynecologic Oncology Clinical Outcomes Registry: From small beginnings come great things.

OBJECTIVE: Clinical registries within medical societies have demonstrated the capacity to promote quality improvement. Opportunities for well-designed data repositories could yield reliable national standards for informing reimbursement, determining adherence to care guidelines, maintaining board certification, and developing bundled payment models. Looking to the future, we set out to develop a gynecologic cancer registry serving the members of the Society of Gynecologic Oncology (SGO). METHODS: The SGO Clinical Outcomes Registry (COR) initiated a web-based data entry platform as a foray into developing a functional registry, compiling data elements specific to gynecologic oncology. Endometrial and ovarian cancer patients began enrollment in early 2014. Within one year, 19 sites were participating with the addition of cervical cancer patients in January 2015. RESULTS: To date, >6500 patients are currently entered from 29 sites, and the COR is being queried to address topics of quality improvement, disparities, and cancer outcomes. CONCLUSIONS: The SGO COR has proven the feasibility of developing a functional gynecologic cancer registry, with high uptake, rapid accrual, and ability to investigate topics of quality and outcome using the COR.

Clinical characteristics associated with racial disparities in endometrial cancer outcomes: A surveillance, epidemiology and end results analysis.

OBJECTIVES: Racial disparities exist for endometrial cancer. We examined patterns of care and factors associated with poor outcomes for Black women with endometrial cancer. METHODS: We studied 110,826 endometrial cancer patients diagnosed between 1980 and 2008 with minimum 5years follow-up in the Surveillance, Epidemiology, and End Results database. Trends over time in sociodemographics, disease characteristics and treatment factors were analyzed over four eras: 1980-1989, 1990-1999, 2000-2004, 2005-2008. Using sequential Cox proportional hazards and Fine-Gray competing risk models we determined the association between potential explanatory variables and racial disparities in all-cause mortality (ACM) and cancer-specific mortality (CSM), respectively. RESULTS: Clinical characteristics of Black and White women were relatively constant over time. The unadjusted hazard ratio (HR) among Black women for ACM and CSM were 1.91 (95% CI 1.86-1.97) and 2.35 (95% CI 2.26-2.43), respectively. Adjustment for sociodemographics, disease presentation and surgery decreased the ACM HR to 1.29 (95% CI 1.24-1.34) and CSM HR to 1.18 (95% CI 1.11-1.26) without further decrease from controlling for radiotherapy. Black women were less likely to undergo operative management even when prescribed. Total and radical hysterectomy, and vaginal brachytherapy (VBT) were associated with improved ACM and CSM. Combination VBT and external beam radiotherapy was associated with improved ACM. CONCLUSION: Racial disparities in endometrial cancer survival are predominantly attributable to increased advanced stage, high-grade and aggressive histologic subtype tumors and differential use of surgery in Black women. Intensified surgical and radiation treatment is associated with improved survival, raising questions about treatment adaptations that may potentially reduce survival disparities.
