Abstract
Objective National data have shown worse endometrial cancer (EC) outcomes among racial and ethnic minorities. We aimed to analyze EC patient outcomes within a large urban academic health system, with a focus on patterns of care and recurrence rates. Methods This was a retrospective chart review of EC patients at three system hospitals from 1/1/07-12/31/17. Demographic and clinical factors, including time from EMB to surgery, rate of chemotherapy completion, persistent or recurrent disease, and palliative care referrals were extracted. Descriptive statistics and survival curves were generated. Analysis was done using SAS version 9.4. Results Black patients had lower overall survival compared to all others on univariate analysis only (p < 0.0001). Hospital site was associated with OS, with the academic anchor and satellite 1 having higher rates of all-cause mortality compared to satellite 2 (HR 4.68 academic anchor, 95 % CI 1.72-12.76, HR 5.36 satellite 1, 95 % CI 1.85-15.52). Time from EMB to surgery and rates of persistent disease following primary treatment were higher in Black patients. After adjusting for stage and grade, chemotherapy completion rate was significantly associated with race. Palliative care was utilized more for Black than White patients after adjusting for stage and grade (p = 0.005). Conclusions Racial disparities in EC are caused by a complex web of interconnected factors that ultimately lead to worse outcomes in Black women. While precision medicine has helped to close the gap, social determinants of health should be addressed, and models focusing on the complex interactions between biologic, genetic, and social factors should be utilized.

Abstract
Importance Disparities in survival exist between non-Hispanic Black (hereafter, Black) and non-Hispanic White (hereafter, White) patients with uterine cancer. Objective To investigate factors associated with racial disparities in survival between Black and White patients with uterine cancer. Design, Setting, and Patients This cohort study used data from the National Cancer Database on 274 838 Black and White patients who received a diagnosis of uterine cancer from January 1, 2004, to December 31, 2017, with follow-up through December 2020. Statistical analysis was performed in July 2022. Main Outcomes and Measures Overall survival by self-reported race and evaluation of explanatory study factors associated with hazard ratio (HR) reduction for Black vs White patients. A propensity scoring approach was applied sequentially to balance racial differences in demographic characteristics, comorbidity score, neighborhood income, insurance status, histologic subtype, disease stage, and treatment. Results The study included 32 230 Black female patients (mean [SD] age at diagnosis, 63.8 [10.0] years) and 242 608 White female patients (mean [SD] age at diagnosis, 63.5 [10.5] years) and had a median follow-up of 74.0 months (range, 43.5-113.8 months). Black patients were more likely than White patients to have low income (44.1% vs 14.0%), be uninsured (5.7% vs 2.6%), present with nonendometrioid histologic characteristics (46.1% vs 21.6%), have an advanced disease stage (34.1% vs 19.8%), receive first-line chemotherapy (33.8% vs 18.2%), and have worse 5-year survival (58.6% vs 78.5%). Among patients who received a diagnosis at younger than 65 years of age, the HR for death for Black vs White patients was 2.43 (95% CI, 2.34-2.52) in a baseline demographic-adjusted model and 1.29 (95% CI, 1.23-1.35) after balancing other factors. Comorbidity score, neighborhood income, insurance status, histologic subtype, disease stage, treatment, and unexplained factors accounted for 0.8%, 7.2%, 11.5%, 53.1%, 5.8%, 1.2%, and 20.4%, respectively, of the excess relative risk (ERR) among the younger Black vs White patients. Among patients 65 years or older, the HR for death for Black vs White patients was 1.87 (95% CI, 1.81-1.93) in the baseline model and 1.14 (95% CI, 1.09-1.19) after balancing other factors. Comorbidity score, neighborhood income, insurance status, histologic subtype, disease stage, treatment, and unexplained factors accounted for 3.0%, 7.5%, 0.0%, 56.2%, 10.6%, 6.9%, and 15.8%, respectively, of the ERR among Black vs White patients aged 65 years or older. Conclusions and Relevance This study suggests that histologic subtype was the dominant factor associated with racial survival disparity among patients with uterine cancer, while insurance status represented the main modifiable factor for women younger than 65 years. Additional studies of interactions between biology and social determinants of health are merited.

Abstract
OBJECTIVE To compare recurrence and survival in patients with stage III endometrial cancer after radical surgery, followed by either adjuvant chemoradiotherapy (ACR) or adjuvant chemotherapy (AC). METHODS We searched for relevant studies in PubMed Central, Embase and the Cochrane Central Register of Controlled Trials. Data were pooled on rates of recurrence as well as rates of progression-free, disease-free and overall survival. Heterogeneity was evaluated using the I2 test. Subgroup and sensitivity analyses were performed to identify potential sources of heterogeneity. RESULTS Data from 18,375 patients in 15 retrospective studies and one randomized controlled trial were meta-analyzed. Compared to the AC group, the ACR showed significantly lower risk of local recurrence (OR 0.43, 95%CI 0.32-0.59) and total recurrence (OR 0.72, 95%CI 0.58-0.89). ACR was also associated with significantly better overall survival (HR 0.66, 95%CI 0.57-0.76), progression-free survival (HR 0.56, 95%CI 0.39-0.81) and disease-free survival (HR 0.66, 95%CI 0.53-0.83). CONCLUSIONS Adding adjuvant radiotherapy to adjuvant chemotherapy after radical surgery may significantly reduce risk of local and overall recurrence, while significantly improving survival of patients with stage III endometrial cancer.

Abstract
The number of cancer survivors continues to increase in the United States due to the growth and aging of the population as well as advances in early detection and treatment. To assist the public health community in better serving these individuals, the American Cancer Society and the National Cancer Institute collaborate triennially to estimate cancer prevalence in the United States using incidence and survival data from the Surveillance, Epidemiology, and End Results cancer registries, vital statistics from the Centers for Disease Control and Prevention's National Center for Health Statistics, and population projections from the US Census Bureau. Current treatment patterns based on information in the National Cancer Database are presented for the most prevalent cancer types by race, and cancer-related and treatment-related side-effects are also briefly described. More than 18 million Americans (8.3 million males and 9.7 million females) with a history of cancer were alive on January 1, 2022. The 3 most prevalent cancers are prostate (3,523,230), melanoma of the skin (760,640), and colon and rectum (726,450) among males and breast (4,055,770), uterine corpus (891,560), and thyroid (823,800) among females. More than one-half (53%) of survivors were diagnosed within the past 10 years, and two-thirds (67%) were aged 65 years or older. One of the largest racial disparities in treatment is for rectal cancer, for which 41% of Black patients with stage I disease receive proctectomy or proctocolectomy compared to 66% of White patients. Surgical receipt is also substantially lower among Black patients with non-small cell lung cancer, 49% for stages I-II and 16% for stage III versus 55% and 22% for White patients, respectively. These treatment disparities are exacerbated by the fact that Black patients continue to be less likely to be diagnosed with stage I disease than White patients for most cancers, with some of the largest disparities for female breast (53% vs 68%) and endometrial (59% vs 73%). Although there are a growing number of tools that can assist patients, caregivers, and clinicians in navigating the various phases of cancer survivorship, further evidence-based strategies and equitable access to available resources are needed to mitigate disparities for communities of color and optimize care for people with a history of cancer.

Abstract
OBJECTIVE Most women diagnosed with endometrial cancer undergo primary surgical management with hysterectomy. Although racial disparities in readmission risk following hysterectomy for non-cancerous conditions have been reported, data among women with endometrial cancer are absent. This study evaluates racial differences in readmission risk among women undergoing endometrial cancer-related hysterectomy. METHODS In the National Cancer Database, women who underwent surgical management for endometrial cancer from 2004 to 2018 were identified. Readmission and minimally invasive hysterectomy (MIH) proportions were plotted according to year of diagnosis and race/ethnicity. Multivariable logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for associations between readmission risk and epidemiological, facility, tumor, and surgical characteristics. A base model was sequentially adjusted to incorporate significant covariates. RESULTS There were 350,631 patients included in the study. The proportion of MIH increased among all race/ethnicities over the study period; however, MIH rates were lower among Black women. Readmission proportions were 2.7% among White, 4.2% among Black, 2.9% among Hispanic, 2.4% among Asian, 2.1% among American Indian/Alaska Native, and 3.1% among Native Hawaiian/Pacific Islander women. In the fully adjusted model incorporating surgical approach, Black women (OR: 1.20, 95% CI = 1.13, 1.28) and Native Hawaiian/Pacific Islander women (OR: 1.54, 95% CI = 1.09, 2.18) were more commonly readmitted compared to White women. CONCLUSIONS In this study, Black and Native Hawaiian/Pacific Islander women with endometrial cancer had significantly higher readmission risk than White women. Optimizing perioperative care for minority women is an essential component of overcoming racially disparate endometrial cancer outcomes.

Abstract
Importance Uterine cancer incidence has been increasing, particularly rates of aggressive, nonendometrioid subtypes, which are disproportionately higher among non-Hispanic Black women. The association of subtype-specific trends with uterine cancer mortality and with the role of tumor subtype and stage at diagnosis with racial disparities in uterine cancer deaths at the population-based level are not known. Objective To estimate histologic subtype- and stage-specific uterine cancer mortality rates by race and ethnicity, corrected for hysterectomy. Design, Setting, and Participants This cohort study used the US Surveillance, Epidemiology, and End Results-18 Incidence-Based Mortality database, representing approximately 26% of the US population and including deaths that occurred from 2000 to 2017. Hysterectomy correction was based on hysterectomy prevalence data from the Behavioral Risk Factor Surveillance System. Uncorrected and corrected rates associated with uterine corpus cancer cases diagnosed between 2000 and 2017 and uterine corpus cancer deaths occurring between 2010 and 2017 were age-adjusted to the 2000 US standard population and are expressed per 100 000 person-years, and annual percent changes in rates were calculated using log-linear regression. Data analysis was performed from March 10 to May 20, 2021. Exposures Tumor histologic subtype, cancer stage at diagnosis, and race and ethnicity. Results Among 208 587 women diagnosed with uterine cancer during 2000-2017 (15 983 [7.7%] were Asian; 20 302 [9.7%] Black; 23 096 [11.1%] Hispanic; and 149 206 [71.5%] White individuals), there were 16 797 uterine cancer deaths between 2010 and 2017, corresponding to a hysterectomy-corrected mortality rate of 15.7 per 100 000 person-years. Hysterectomy-corrected rates were highest among Black women, overall, by histologic subtype and stage at diagnosis. Among all women, uterine corpus cancer mortality rates increased significantly by 1.8% (95% CI, 1.5%-2.9%) per year from 2010 to 2017, as did rates of nonendometrioid carcinomas (2.7%; 95% CI, 1.8%-3.6%), with increases occurring in Asian (3.4%; 95% CI, 0.3%-6.6%), Black (3.5%; 95% CI, 2.2%-4.9%), Hispanic (6.7%; 95% CI, 1.9%-11.8%), and White women (1.5%; 95% CI, 0.6%-2.4%). In contrast, endometrioid carcinoma mortality rates remained stable. Conclusions and Relevance The findings of this cohort study suggest a significant increase of nonendometrioid uterine carcinoma mortality rates, aligning with recent incidence trends. The factors associated with these trends are not well understood and require more investigation of possible mechanisms. Despite stable incidence rates, endometrioid cancer mortality rates have not decreased over the past decade at the population level, suggesting limited progress in treatment for these cancers. The substantial disparities in uterine corpus cancer mortality rates among non-Hispanic Black women cannot be fully explained by subtype distribution and stage at diagnosis.

Abstract
BACKGROUND Disparities in adjuvant treatment between Black and White women with endometrial cancer exist and contribute to worse outcomes among Black women. However, factors leading to disparate treatment receipt are understudied. OBJECTIVE We examined whether patient refusal of adjuvant treatment (chemotherapy or radiation) differed between Black and White women and whether treatment refusal mediated racial disparities in survival among women with endometrial cancer. STUDY DESIGN We used the National Cancer Database, a hospital-based cancer registry, to identify non-Hispanic Black and non-Hispanic White women diagnosed with endometrial cancer from 2004 to 2016 who either received or refused recommended radiation or chemotherapy. We used logistic regression to estimate multivariable-adjusted odds ratios and 95% confidence intervals for associations between race and treatment refusal. We also examined predictors of treatment refusal in race-specific models. Accelerated failure time models were used to estimate absolute differences in overall survival by race. We used causal mediation analysis to estimate the proportion of racial differences in overall survival attributable to racial differences in adjuvant treatment refusal. We considered the overall study population and strata defined by histology, and adjusted for sociodemographic, tumor, and facility characteristics. RESULTS Our analysis included 75,447 endometrial cancer patients recommended to receive radiation and 60,187 endometrial cancer patients recommended to receive chemotherapy, among which 6.4% and 11.4% refused treatment, respectively. Among Black women recommended for radiation or chemotherapy, 6.4% and 9.6% refused, respectively. Among White women recommended for radiation or chemotherapy, 6.4% and 11.8% refused, respectively. After adjusting for sociodemographic variables, facility characteristics, and tumor characteristics, Black women were more likely to refuse chemotherapy than White women (adjusted odds ratio, 1.26; 95% confidence interval, 1.15-1.37), but no difference in radiation refusal was observed (adjusted odds ratio, 1.00; 95% confidence interval, 0.91-1.11). Some predictors of radiation refusal varied by race, namely income, education, histology, stage, and chemotherapy receipt (P interactions<.05), whereas predictors of chemotherapy refusal were generally similar between Black and White women. Among women recommended for radiation, Black women survived an average of 4.3 years shorter than White women, which did not seem attributable to differences in radiation refusal. Among women recommended for chemotherapy, Black women survived an average of 3.2 years shorter than White women of which 1.9 months (4.9%) could potentially be attributed to differences in chemotherapy refusal. CONCLUSION We observed differences in chemotherapy refusal by race, and those differences may be responsible for up to about 2 months of the overall 3.2-year survival disparity between White and Black women. Radiation refusal did not explain any of the 4.3-year disparity among women recommended for radiation. Treatment refusal accounts for, at most, a small fraction of the total racial disparity in endometrial cancer survival. Although a better understanding of the reasons for patient treatment refusal and subsequent intervention may help improve outcomes for some women, other causes of disparate outcomes, particularly those reflecting the social determinants of health, must be investigated.

Abstract
Background Endometrial carcinoma (EC) is one of the most common gynecological malignant tumors. In this study, we constructed gene co-expression networks to identify key modules and hub genes involved in the pathogenesis of EC. Results The MEturquoise module was found to be significantly related to hypertension and the MEbrown module was significantly related to the history of other malignancies. Functional enrichment analysis showed that the MEturquoise module was associated with the GO biological process terms of transcription from RNA polymerase II promoter, positive regulation of male gonad development, endocardial cushion development, and endothelial cell differentiation. The MEbrown module was associated with GO terms DNA binding, epithelial-to-mesenchymal transition, and transcription from RNA polymerase II promoter. A total of 10 hub genes were identified and compared with the available datasets at transcriptional and translational levels. Conclusions The identified ceRNAs may play a critical role in the progression and metastasis of EC and are thus candidate therapeutic targets and potential prognostic biomarkers. The two modules constructed further provide a useful reference that will advance understanding of the mechanisms of tumorigenesis in EC.

Abstract
Treatment advances over the past five decades have resulted in significant improvements in survival from childhood cancer. Although survival rates are relatively high, social disparities in outcomes have been sometimes observed. In a population-based study, we investigated social inequalities by sex and deprivation in treatment receipt in childhood cancer in Ireland. Cancers incident in people aged 0 to 19 during 1994 to 2012 and treatments received were abstracted from the National Cancer Registry Ireland. Multivariable modified Poisson regression with robust error variance (adjusting for age, and year) was used to assess associations between sex and deprivation category of area of residence at diagnosis and receipt of cancer-directed surgery, chemotherapy or radiotherapy. Three thousand seven hundred and four childhood cancers were included. Girls were significantly less likely than boys to receive radiotherapy for leukemia overall (relative risk [RR] = 0.70; 95% confidence interval [CI] = 0.50-0.98), and acute lymphoblastic leukemia specifically (RR = 0.54; 95% CI = 0.36-0.79), and surgery for central nervous system (CNS) overall (RR = 0.83; 95% CI = 0.74-0.93) and other CNS (RR = 0.76; 95% CI = 0.60-0.96). Girls were slightly less likely to receive chemotherapy for non-Hodgkin lymphoma and surgery for Hodgkin lymphoma (HL), but these results were not statistically significant. Children residing in more deprived areas were significantly less likely to receive chemotherapy for acute myeloid leukemia or surgery for lymphoma overall and HL, but more likely to receive chemotherapy for medulloblastoma. These results may suggest social inequalities in treatment receipt for childhood cancers. Further research is warranted to explore whether similar patterns are evident in other childhood cancer populations and to better understand the reasons for the findings.

Abstract
OBJECTIVE Gaps in access to appropriate cancer care, and associated cancer mortality, have widened across socioeconomic groups. We examined whether demographic and socioeconomic factors influenced receipt of adjuvant radiation therapy (RT) in patients with high-risk, early-stage endometrial cancer. METHODS A retrospective study cohort was selected from 349,404 endometrial carcinoma patients from the National Cancer Database in whom adjuvant RT would be recommended per national guidelines. The study included surgically treated patients with endometrioid endometrial cancer with one of the following criteria: 1) FIGO 2009 stage IB, grade 1/2 disease, age ≥ 60 years; 2) stage IB, grade 3 disease; or 3) stage II disease. Logistic regression analysis was performed to identify factors associated with omission of adjuvant RT. Association between adjuvant RT, covariables, and overall survival (OS) was assessed with multivariable Cox proportional hazards models. RESULTS 19,594 patients were eligible for analysis; 47% did not receive adjuvant RT. Omission of adjuvant RT was more prevalent among African-American, Hispanic, and Asian compared to non-Hispanic white patients (OR 0.79, 95%CI: 0.69-0.91; OR 0.75, 95%CI: 0.64-0.87; OR 0.75, 95%CI: 0.60-0.94, respectively). Lower median household income of patient's area of residence, lack of health insurance, treatment at non-academic hospitals, farther distance to treatment facilities, and residence in metropolitan counties were associated with omission of adjuvant RT. Such omission was independently associated with worse OS (HR1.43, p < 0.001). CONCLUSION Adjuvant RT is omitted in 47% of patients with early-stage, high-risk endometrial cancer, which is associated with poor access to appropriate, high-quality care and worse outcome.

Abstract
BACKGROUND Differences in receipt of guideline-concordant treatment might underlie well-established racial disparities in endometrial cancer mortality. OBJECTIVE Using the National Cancer Database, we assessed the hypothesis that among women with endometrioid endometrial cancer, racial/ethnic minority women would have lower odds of receiving guideline-concordant treatment than white women. In addition, we hypothesized that lack of guideline-concordant treatment was linked with worse survival. STUDY DESIGN We defined receipt of guideline-concordant treatment using the National Comprehensive Cancer Network guidelines. Multivariable logistic regression models were used to compute odds ratios and 95% confidence intervals for associations between race and guideline-concordant treatment. We used multivariable Cox proportional hazards regression models to estimate hazards ratios and 95% confidence intervals for relationships between guideline-concordant treatment and overall survival in the overall study population and stratified by race/ethnicity. RESULTS This analysis was restricted to the 89,319 women diagnosed with an invasive, endometrioid endometrial cancer between 2004 and 2014. Overall, 74.7% of the cohort received guideline-concordant treatment (n = 66,699). Analyses stratified by race showed that 75.3% of non-Hispanic white (n = 57,442), 70.1% of non-Hispanic black (n = 4334), 71.0% of Hispanic (n = 3263), and 72.5% of Asian/Pacific Islander patients (n = 1660) received treatment in concordance with guidelines. In multivariable-adjusted models, non-Hispanic black (odds ratio, 0.92, 95% confidence interval, 0.86-0.98) and Hispanic women (odds ratio, 0.90, 95% confidence internal, 0.83-0.97) had lower odds of receiving guideline-concordant treatment compared with non-Hispanic white women, while Asian/Pacific Islander women had a higher odds of receiving guideline-concordant treatment (odds ratio, 1.11, 95% confidence interval, 1.00-1.23). Lack of guideline-concordant treatment was associated with lower overall survival in the overall study population (hazard ratio, 1.12, 95% confidence interval, 1.08-1.15) but was not significantly associated with overall survival among non-Hispanic black (hazard ratio, 1.09, 95% confidence interval, 0.98-1.21), Hispanic (hazard ratio, 0.92, 95% confidence interval=0.78-1.09), or Asian/Pacific Islander (hazard ratio, 0.90, 95% confidence interval, 0.70-1.16) women. CONCLUSION Non-Hispanic black and Hispanic women were less likely than non-Hispanic white women to receive guideline-concordant treatment, while Asian/Pacific Islander women more commonly received treatment in line with guidelines. Furthermore, in the overall study population, overall survival was worse among those not receiving guideline-concordant treatment, although low power may have had an impact on the race-stratified models. Future studies should evaluate reasons underlying disparate endometrial cancer treatment.

Abstract
BACKGROUND Among women diagnosed with non-endometrioid endometrial carcinoma (EC), we investigated associations between race/ethnicity and receipt of guideline-concordant treatment (GCT), as well as relationships between GCT and survival. METHODS We used the National Cancer Database and identified 21,177 non-Hispanic White (NHW), 6657 non-Hispanic Black (NHB), 1689 Hispanic, and 903 Asian/Pacific Islander (AS/PI) women diagnosed with non-endometrioid EC between 2004 and 2014. Year-specific National Comprehensive Cancer Network (NCCN) guidelines were used to classify GCT. We used multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between race/ethnicity and GCT receipt. Multivariable-adjusted Cox proportional hazards models were used to estimate hazards ratios (HRs) and 95% CIs for relationships between GCT and overall survival in the total study population and stratified by race/ethnicity. RESULTS Overall, 43.8% of women with non-endometrioid EC received GCT. Compared to NHW women, NHB (OR = 1.01, 95% CI = 0.95-1.07), Hispanic (OR = 1.01, 95% CI = 0.91-1.12) and AS/PI women (OR = 1.10, 95% CI = 0.96-1.26) did not have significantly different odds of receiving GCT. GCT was significantly associated with improved survival among NHW (HR = 0.84, 95% CI = 0.80-0.87), NHB (HR = 0.85, 95% CI = 0.80-0.91), and Hispanic women (HR = 0.84, 95% CI = 0.72-0.98) but not among AS/PI women (HR = 0.97, 95% CI = 0.78-1.19). CONCLUSIONS While more than half of women with non-endometrioid EC did not receive GCT, no difference in GCT receipt by race/ethnicity was observed. When received, GCT was associated with improved survival in almost all racial groups. Interventions to improve GCT adherence may improve survival for most women with non-endometrioid EC.
