Abstract
OBJECTIVES Primary mucinous ovarian carcinoma represents 3% of ovarian cancers and is typically diagnosed early, yielding favorable outcomes. This study aims to identify risk factors, focussing on the impact of age and ethnicity on survival from primary mucinous ovarian cancer. METHODS A retrospective observational study of patients treated at Sandwell and West Birmingham Hospitals NHS Trust and University Hospital Coventry and Warwickshire. Patients included were women aged ≥16 years, with primary mucinous ovarian cancer confirmed by specialist gynecological histopathologist and tumor immunohistochemistry, including cytokeratin-7, cytokeratin-20, and CDX2. Statistical analyses were performed using R integrated development environment, with survival assessed by Cox proportional hazards models and Kaplan-Meier plots. RESULTS A total of 163 patients were analyzed; median age at diagnosis was 58 years (range 16-92), 145 (89%) were International Federation of Gynecology and Obstetrics stage I and 43 (26%) patients had infiltrative invasion. Women aged ≤45 years were more likely to have infiltrative invasion (RR=1.38, 95% CI 0.78 to 2.46), with increased risk of death associated with infiltrative invasion (HR=2.29, 95% CI 1.37 to 5.83). Compared with White counterparts, South Asian women were more likely to undergo fertility-sparing surgery (RR=3.52, 95% CI 1.48 to 8.32), and have infiltrative invasion (RR=1.25, 95% CI 0.60 to 2.58). South Asian women undergoing fertility-sparing surgery had worse prognosis than those undergoing traditional staging surgery (HR=2.20, 95% CI 0.39 to 13.14). In FIGO stage I disease, 59% South Asian and 37% White women received adjuvant chemotherapy (p=0.06). South Asian women exhibited a worse overall prognosis than White women (HR=2.07, 95% CI 0.86 to 4.36), particularly pronounced in those aged ≤45 years (HR=8.75, 95% CI 1.22 to 76.38). CONCLUSION This study identified young age as a risk factor for diagnosis of infiltrative invasion. Fertility-sparing surgery in South Asian women is a risk factor for poorer prognosis. South Asian women exhibit poorer overall survival than their White counterparts.

The Association between Mediated Deprivation and Ovarian Cancer Survival among African American Women. Cancers (Basel) 2023; 15:4848. [PMID: 37835542 PMCID: PMC10571563 DOI: 10.3390/cancers15194848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 09/25/2023] [Accepted: 10/02/2023] [Indexed: 10/15/2023] Open
Abstract
BACKGROUND Deprivation indices are often used to adjust for socio-economic disparities in health studies. Their role has been partially evaluated for certain population-level cancer outcomes, but examination of their role in ovarian cancer is limited. In this study, we evaluated a range of well-recognized deprivation indices in relation to cancer survival in a cohort of self-identified Black women diagnosed with ovarian cancer. This study aimed to determine if clinical or diagnostic characteristics lie on a mediating pathway between socioeconomic status (SES) and deprivation and ovarian cancer survival in a minority population that experiences worse survival from ovarian cancer. METHODS We used mediation analysis to look at the direct and indirect causal effects of deprivation indices with main mediators of the SEER stage at diagnosis and residual disease. The analysis employed Bayesian structural equation models with variable selection. We applied a joint Bayesian structural model for the mediator, including a Weibull mixed model for the vital outcome with deprivation as exposure. We selected modifiers via a Monte Carlo model selection procedure. RESULTS The results suggest that high SES-related indices, such as Yost, Kolak urbanicity (URB), mobility (MOB) and SES dimensions, and concentrated disadvantage index (CDI), all have a significant impact on improved survival. In contrast, area deprivation index (ADI)/Singh, and area level poverty (POV) did not have a major impact. In some cases, the indirect effects have very wide credible intervals, so the total effect is not well estimated despite the estimation of the direct effect. CONCLUSIONS First, it is clear that commonly used indices such as Yost, or CDI both significantly impact the survival experience of Black women diagnosed with epithelial ovarian cancer. In addition, the Kolak dimension indices (URB, MOB, mixed immigrant: MICA and SES) also demonstrate a significant association, depending on the mediator. Mediation effects differ according to the mediator chosen.

Abstract
PURPOSE Deprivation and segregation indices are often examined as possible explanations for observed health disparities in population-based studies. In this study, we assessed the role of recognized deprivation and segregation indices specifically as they affect survival in a cohort of self-identified Black women diagnosed with ovarian cancer who enrolled in the African American Cancer Epidemiology Study. METHODS Mediation analysis was used to examine the direct and indirect effects between deprivation or segregation and overall survival via a Bayesian structural equation model with Gibbs variable selection. RESULTS The results suggest that high socioeconomic status-related indices have an association with increased survival, ranging from 25% to 56%. In contrast, index of concentration at the extremes-race does not have a significant impact on overall survival. In many cases, the indirect effects have very wide credible intervals; consequently, the total effect is not well estimated despite the estimation of the direct effect. CONCLUSIONS Our results show that Black women living in higher socioeconomic status neighborhoods are associated with increased survival with ovarian cancer using area-level economic indices such as Yost or index of concentration at the extremes-income. In addition, the Kolak urbanization index has a similar impact and highlights the importance of area-level deprivation and segregation as potentially modifiable social factors in ovarian cancer survival.

Health-care access dimensions and ovarian cancer survival: SEER-Medicare analysis of the ORCHiD study. JNCI Cancer Spectr 2023; 7:pkad011. [PMID: 36794910 PMCID: PMC10066801 DOI: 10.1093/jncics/pkad011] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 02/07/2023] [Accepted: 02/13/2023] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND Racial and ethnic disparities in ovarian cancer (OC) survival are well-documented. However, few studies have investigated how health-care access (HCA) contributes to these disparities. METHODS To evaluate the influence of HCA on OC mortality, we analyzed 2008-2015 Surveillance, Epidemiology, and End Results-Medicare data. Multivariable Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between HCA dimensions (affordability, availability, accessibility) and OC-specific and all-cause mortality, adjusting for patient characteristics and treatment receipt. RESULTS The study cohort included 7590 OC patients: 454 (6.0%) Hispanic, 501 (6.6%) Non-Hispanic (NH) Black, and 6635 (87.4%) NH White. Higher affordability (HR = 0.90, 95% CI = 0.87 to 0.94), availability (HR = 0.95, 95% CI = 0.92 to 0.99), and accessibility scores (HR = 0.93, 95% CI = 0.87 to 0.99) were associated with lower risk of OC mortality after adjusting for demographic and clinical factors. Racial disparities were observed after additional adjustment for these HCA dimensions: NH Black patients experienced a 26% higher risk of OC mortality compared with NH White patients (HR = 1.26, 95% CI = 1.11 to 1.43) and a 45% higher risk among patients who survived at least 12 months (HR = 1.45, 95% CI = 1.16 to 1.81). CONCLUSIONS HCA dimensions are statistically significantly associated with mortality after OC and explain some, but not all, of the observed racial disparity in survival of patients with OC. Although equalizing access to quality health care remains critical, research on other HCA dimensions is needed to determine additional factors contributing to disparate OC outcomes by race and ethnicity and advance the field toward health equity.

Abstract
IMPORTANCE Poor health care access (HCA) is associated with racial and ethnic disparities in ovarian cancer (OC) survival. OBJECTIVE To generate composite scores representing health care affordability, availability, and accessibility via factor analysis and to evaluate the association between each score and key indicators of guideline-adherent care. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used data from patients with OC diagnosed between 2008 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) Medicare database. The SEER Medicare database uses cancer registry data and linked Medicare claims from 12 US states. Included patients were Hispanic, non-Hispanic Black, and non-Hispanic White individuals aged 65 years or older diagnosed from 2008 to 2015 with first or second primary OC of any histologic type (International Classification of Diseases for Oncology, 3rd Edition [ICD-O-3] code C569). Data were analyzed from June 2020 to June 2022. EXPOSURES The SEER-Medicare data set was linked with publicly available data sets to obtain 35 variables representing health care affordability, availability, and accessibility. A composite score was created for each dimension using confirmatory factor analysis followed by a promax (oblique) rotation on multiple component variables. MAIN OUTCOMES AND MEASURES The main outcomes were consultation with a gynecologic oncologist for OC and receipt of OC-related surgery in the 2 months prior to or 6 months after diagnosis. RESULTS The cohort included 8987 patients, with a mean (SD) age of 76.8 (7.3) years and 612 Black patients (6.8%), 553 Hispanic patients (6.2%), and 7822 White patients (87.0%). Black patients (adjusted odds ratio [aOR], 0.75; 95% CI, 0.62-0.91) and Hispanic patients (aOR, 0.81; 95% CI, 0.67-0.99) were less likely to consult a gynecologic oncologist compared with White patients, and Black patients were less likely to receive surgery after adjusting for demographic and clinical characteristics (aOR, 0.76; 95% CI, 0.62-0.94). HCA availability and affordability were each associated with gynecologic oncologist consultation (availability: aOR, 1.16; 95% CI, 1.09-1.24; affordability: aOR, 1.13; 95% CI, 1.07-1.20), while affordability was associated with receipt of OC surgery (aOR, 1.08; 95% CI, 1.01-1.15). In models mutually adjusted for availability, affordability, and accessibility, Black patients remained less likely to consult a gynecologic oncologist (aOR, 0.80; 95% CI, 0.66-0.97) and receive surgery (aOR, 0.80; 95% CI, 0.65-0.99). CONCLUSIONS AND RELEVANCE In this cohort study of Hispanic, non-Hispanic Black, and non-Hispanic White patients with OC, HCA affordability and availability were significantly associated with receiving surgery and consulting a gynecologic oncologist. However, these dimensions did not fully explain racial and ethnic disparities.

Abstract
Socioeconomic indexes are widely used in public health to facilitate neighborhood-scale analyses. Although they are calculated with high levels of precision, they are rarely reported with accompanying measures of uncertainty (e.g., 90% confidence intervals). Here we use the variance replicate tables that accompany the United States Census Bureau's American Community Survey to report confidence intervals around the Yost Index, a socioeconomic index comprising seven variables that is frequently used in cancer surveillance. The Yost Index is reported as a percentile score from 1 (most affluent) to 100 (most deprived). We find that the average uncertainty for a census tract in the United States is plus or minus 8 percentiles, with the uncertainty a function of the value of the index itself. Scores at the extremes of the distribution are more precise and scores near the center are less precise. Less-affluent tracts have greater uncertainty than corresponding more-affluent tracts. Fewer than 50 census tracts of 72,793 nationally have unusual distributions of socioeconomic conditions that render the index uninformative. We demonstrate that the uncertainty in a census-based socioeconomic index is calculable and can be incorporated into any analysis using such an index.

Abstract
The difference in cancer morbidity and mortality between individuals of different racial groups is complex. Health disparities provide a framework to explore potential connections between poor outcomes and individuals of different racial backgrounds. This study identifies genomic changes in African-American patients with gynecologic malignancies, a population with well-established disparities in outcomes. Our data explore whether social health disparities might mediate interactions between the environment and tumor epigenomes and genomes that can be identified. Using The Cancer Genetic Ancestry Atlas, which encodes data from The Cancer Genome Atlas by ancestry and allows for systematic analyses of sequencing data by racial group, we performed large-scale, comparative analyses to identify novel targets with alterations in methylation, transcript, and microRNA expression between tumors from women of European American or African American racial groups across all gynecologic malignancies. We identify novel discrete genomic changes in these complex malignancies and suggest a framework for identifying novel therapeutic targets for future investigation.

Abstract
Purpose To identify patient and hospital characteristics associated with extended surgical cytoreduction in the treatment of ovarian cancer. Methods A retrospective analysis using the National Inpatient Sample (NIS) database identified women hospitalized for surgery to remove an ovarian malignancy between 2013 and 2017. Extended cytoreduction (ECR) was defined as surgery involving the bowel, liver, diaphragm, bladder, stomach, or spleen. Chi-square and logistic regression were used to analyze patient and hospital demographics related to ECR, and trends were assessed using the Cochran-Armitage test. Results Of the estimated 79,400 patients undergoing ovarian cancer surgery, 22% received ECR. Decreased adjusted odds of ECR were found in patients with lower Elixhauser Comorbidity Index (ECI) scores (OR 0.61, p<0.001 for ECI 2, versus ECI≥3) or residence outside the top income quartile (OR 0.71, p<0.001 for Q1, versus Q4), and increased odds were seen at hospitals with high ovarian cancer surgical volume (OR 1.25, p<0.001, versus low volume). From 2013 to 2017, there was a decrease in the proportion of cases with extended procedures (19% to 15%, p<0.001). There were significant decreases in the proportion of cases with small bowel, colon, and rectosigmoid resections (p<0.001). Patients who underwent ECR were more likely treated at a high surgical volume hospital (37% vs 31%, p<0.001) over the study period. For their hospital admission, patients who underwent ECR had increased mortality (1.6% vs. 0.5%, p<0.001), length of stay (9.6 days vs. 5.2 days, p<0.001), and mean cost ($32,132 vs. $17,363, p<0.001). Conclusions Likelihood of ECR was associated with increased medical comorbidity complexity, higher income, and undergoing the procedure at high surgical volume hospitals. The proportion of ovarian cancer cases with ECR has decreased from 2013–17, with more cases performed at high surgical volume hospitals.

Abstract
Peritoneal surface malignancies are a group of aggressive cancers involving the peritoneum. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy can improve outcomes and survival in select patients. Despite significant advancements in care, racial disparities in peritoneal malignancy outcomes persist and may have even worsened over time. Poor adherence to guideline-recommended therapy introduces wide variability in patient care and often results in fewer options and suboptimal treatment of vulnerable populations. This review explores biological, sociodemographic, and environmental factors that contribute to disparities in peritoneal malignancy outcomes.

Abstract
Introduction Ovarian cancer is the fifth-leading cause of cancer-related mortality in US women. There are survival disparities between non-Hispanic black (NHB) and non-Hispanic white (NHW) women. We assessed if insurance status or extent of disease modified the effect of race/ethnicity on survival for ovarian cancer. Methods A historical cohort was assembled using the 2007-2015 National Cancer Institute’s Surveillance, Epidemiology, and End Result (SEER) dataset. Adult NHB and NHW (>18 years) diagnosed with regional and distant ovarian cancer were included. The outcome was five-year cause-specific mortality. Multivariable Cox regression models were fitted, including race by the extent of disease and race by insurance status interaction terms. Results For each significant interaction, separate Cox models were fitted. In total 8,043 women were included. The insurance status/race interaction was not statistically significant, but the extent of disease modified the effect of race on survival. NHB survival was lower in regional disease (adjusted hazard ratio (HR) =1.6; 95% confidence interval (CI) 1.1-2.4), while there was no difference in survival between women with distant disease (adjusted HR =1.0; 95%CI 0.9-1.2). Conclusions Ovarian cancer mortality is similar between NHB and NHW women with the distant disease but higher in NHB women with regional disease. Further research should clarify whether this difference is due to access to quality cancer treatment or other factors affecting treatment response.

Clinicopathologic significance and race-specific prognostic association of MYB overexpression in ovarian cancer. Sci Rep 2021; 11:12901. [PMID: 34145334 PMCID: PMC8213794 DOI: 10.1038/s41598-021-92352-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 06/03/2021] [Indexed: 02/02/2023] Open
Abstract
Late diagnosis, unreliable prognostic assessment, and poorly-guided therapeutic planning result in dismal survival of ovarian cancer (OC) patients. Therefore, identifying novel functional biomarker(s) is highly desired for improved clinical management. MYB is an oncogenic transcription factor with emerging functional significance in OC. Here we examined its clinicopathologic significance by immunohistochemistry and TCGA/GTex data analyses. Aberrant MYB expression was detected in 94% of OC cases (n = 373), but not in the normal ovarian tissues (n = 23). MYB was overexpressed in all major epithelial OC histological subtypes exhibiting the highest incidence (~ 97%) and overall expression in serous and mucinous carcinomas. MYB expression correlated positively with tumor grades and stages. Moreover, MYB exhibited race-specific prognostic association. Moderate-to-high MYB levels were significantly associated with both poor overall- (p = 0.02) and progression-free (p = 0.02) survival in African American (AA), but not in the Caucasian American (CA) patients. Consistent with immunohistochemistry data, we observed significantly higher MYB transcripts in OC cases (n = 426) than normal ovary (n = 88). MYB transcripts were significantly higher in all epithelial OC subtypes, compared to normal, and its greater levels predicted poor survival in AA OC, but not CA OC, patients. Thus, MYB appears to be a useful clinical biomarker for prognostication, especially in AA patients.

Abstract
OBJECTIVE To describe the participation of minority women in clinical trials using immunologic agents for breast and gynecologic cancers. METHODS A retrospective review of completed clinical trials involving immunotherapy for breast and gynecologic cancers was performed. Completed trials were examined for data on race, tumor type, and start year. Minority enrollment was stratified by tumor site. Based on Center for Disease Control and Prevention age-adjusted incidence for race, expected and observed ratios of racial participation were calculated and compared using Χ2 testing, p≤0.05. RESULTS A total of 53 completed immunotherapy clinical trials involving 8820 patients were reviewed. Breast cancer trials were most common (n=24) and involved the most patients (n=6248, 71%). Racial breakdown was provided in 41 studies (77%) for a total of 7201 patients. Race reporting was lowest in uterine (n=4, 67%) and cervical cancer trials (n=6, 67%), and highest in ovarian cancer trials (n=12, 86%). White patients comprised 70% (n=5022) of all the patients included. Only 5% of patients involved were black (n=339), and 83% of these patients (n=282) were enrolled in breast cancer trials. Observed enrollment of black women was 32-fold lower for ovarian, 19-fold lower for cervical, 15-fold lower for uterine, and 11-fold lower for breast cancer than expected. While all trials reported race between 2013 and 2015, no consistent trend was seen towards increasing race reporting or in enrollment of black patients over time. CONCLUSION Racial disparities exist in clinical trials evaluating immunologic agents for breast and gynecologic cancers. Recruitment of black women is particularly low. In order to address inequity in outcomes for these cancers, it is crucial that significant attention be directed towards minority representation in immuno-oncologic clinical trials.

Abstract
BACKGROUND This study examined the impact of geographic distance on survival outcomes for patients receiving treatment for ovarian cancer at the only NCI-designated cancer center (NCI-CC) in Kansas. METHODS We identified ovarian cancer patients treated at the University of Kansas Cancer Center between 2010 and 2015. Demographic factors and clinical characteristics were abstracted. The main outcome measure was overall survival according to geographic distance from the institution. Kaplan Meier survival curves and Cox proportional hazard models were generated using SAS v9.4. RESULTS 220 patients were identified. Survival analysis based on distance from the institution demonstrated that patients who lived ≤10 miles from the institution had worse overall survival (p = 0.0207) and were more likely to have suboptimal cytoreductive surgery (p = 0.0276). Lower estimated median income was also associated with a 1.54 increased risk of death, 95% CI (1.031-2.292), p = 0.0347. CONCLUSIONS We determined that ovarian cancer survival disparities exist in our patient population. Lower rates of optimal cytoreductive surgery has been identified as a possible driver of poor prognosis for patients who lived in proximity to our institution.

Abstract
BACKGROUND Food deserts are neighborhoods with low access to healthy foods and are associated with poor health metrics. We investigated association of food desert residence and cancer outcomes. METHODS In this population-based study, data from the 2000-2012 California Cancer Registry was used to identify patients with stage II/III breast or colorectal cancer. Patient residence at time of diagnosis was linked by census tract to food desert using the USDA Food Access Research Atlas. Treatment and outcomes were compared by food desert residential status. RESULTS Among 64,987 female breast cancer patients identified, 66.8% were < 65 years old, and 5.7% resided in food deserts. Five-year survival for food desert residents was 78% compared with 80% for non-desert residents (p < 0.0001). Among 48,666 colorectal cancer patients identified, 50.4% were female, 39% were > 65 years old, and 6.4% resided in food deserts. Five-year survival for food desert residents was 60% compared with 64% for non-desert residents (p < 0.001). Living in food deserts was significantly associated with diabetes, tobacco use, poor insurance coverage, and low socioeconomic status (p < 0.05) for both cancers. There was no significant difference in rates of surgery or chemotherapy by food desert residential status for either diagnosis. Multivariable analyses showed that food desert residence was associated with higher mortality. CONCLUSION Survival, despite treatment for stage II/III breast and colorectal cancers was worse for those living in food deserts. This association remained significant without differences in use of surgery or chemotherapy, suggesting factors other than differential care access may link food desert residence and cancer outcomes.

Abstract
BACKGROUND The differential occurrence of second primary cancers by race following ovarian cancer is poorly understood. Our objective was to determine the incidence of second primary gynecologic cancers (SPGC) following definitive therapy for ovarian cancer. Specifically, we aimed to determine differences in SPGC incidence by Asian ethnic subgroups. METHODS We identified 27,602 women ages 20 years and older and diagnosed with first primary epithelial ovarian cancer between 2000 and 2016 who received surgery and chemotherapy in 18 population-based Surveillance, Epidemiology and End Results Program registries. We compared the incidence of SPGC with expected incidence rates in the general population of women using estimated standardized incidence ratios (SIR) and 95% confidence intervals (CI). RESULTS The incidence of SPGC was lower among White women (SIR = 0.73; 95% CI, 0.59-0.89), and higher among Black (SIR = 1.80; 95% CI, 0.96-3.08) and Asian/Pacific Islander (API) women (SIR = 1.83; 95% CI, 1.07-2.93). Increased risk of vaginal cancers was observed among all women, although risk estimates were highest among API women (SIR = 26.76; 95% CI, 5.52-78.2) and were also significant for risk of uterine cancers (SIR = 2.53; 95% CI, 1.35-4.33). Among API women, only Filipinas had significantly increased incidence of SPGC overall including both uterine and vaginal cancers. CONCLUSIONS Risk of SPGC following treatment of ovarian cancer differs by race and ethnicity, with Filipina women having the highest rates of second gynecologic cancers among Asian women. IMPACT Ensuring access and adherence to surveillance may mitigate ethnic differences in the early detection and incidence of second gynecologic cancers.

Abstract
Background: Hysterectomy can be performed with concomitant bilateral salpingo-oophorectomy (BSO) to treat symptomatic pathology of the ovary (e.g., endometriosis) or to prevent ovarian cancer. Our objective was to examine the relationship between race and concomitant BSO by menopausal status in the Veterans Affairs (VA) health care system. Methods: This is a longitudinal study utilizing VA administrative data to identify hysterectomies provided or paid for by VA (i.e., source of care) between 2007 and 2014. We defined BSO as removal of both ovaries and fallopian tubes at the time of hysterectomy, identified by International Classification of Diseases-Ninth Revision codes. Covariates included demographic (e.g., ethnicity) and gynecological diagnoses (e.g., endometriosis). We used generalized linear models with a log-link and binomial distribution to estimate associations of race with BSO by menopausal status and source of care. Results: We identified 6,785 Veterans with hysterectomies, including 2,320 with concomitant BSO. Overall, Black Veterans were more likely to be single, obese, and undergo abdominal hysterectomy. After adjustment, premenopausal Black Veterans had a 41% lower odds of BSO than their White counterparts (odds ratio [OR]: 0.59, 95% confidence interval [CI]: 0.51-0.68). Stratifying on source of care, these results remained unchanged (provided: OR: 0.61, 95% CI: 0.52-0.72; paid: OR: 0.58, 95% CI: 0.48-0.71). There was insufficient evidence of an association among postmenopausal Veterans. Conclusions: Premenopausal Black Veterans are less likely to undergo BSO even after adjustment for salient characteristics. Our findings may have implications for equitable gynecological care for Veterans. Additional research is needed to better understand the role of differential preferences or cancer risk in these racial differences.

Abstract
OBJECTIVE To evaluate the influence of marital status and other demographic factors on survival of patients with ovarian cancer. STUDY DESIGN Data were obtained from the Surveillance, Epidemiology, and End Results database from 2010 to 2015. Analyses were performed using Kaplan-Meier and multivariate Cox proportional hazard methods. RESULTS Of 19 643 patients with ovarian cancer (median age 60 years, range 18-99), 16 278 (83%), 1381 (7%), 1856 (9%), and 128 (1%) were White, Black, Asian, and Native American, respectively. The majority of patients (10 769, 55%) were married while 4155 (21%) were single, 2278 (12%) were divorced, and 2441 (12%) were widowed. Patients were more likely to be married if they were Asian (65%) or White (56%) than if they were Black (31%) or Native American (39%) (p<0.001). Most married patients were insured (n=9760 (91%), non-Medicaid) compared with 3002 (72%) of single, 1777 (78%) divorced, and 2102 (86%) of widowed patients (p<0.001). Married patients were more likely to receive chemotherapy than single, divorced, and widowed patients (8515 (79%) vs 3000 (72%), 1747 (77%), and 1650 (68%), respectively; p<0.001). The 5-year disease-specific survival of the overall group was 58%. Married patients had improved survival of 60% compared with divorced (52%) and widowed (44%) patients (p<0.001). On multivariate analysis, older age (HR 1.02, 95% CI 1.016 to 1.021, p<0.001), Black race (HR 1.24, 95% CI 1.11 to 1.38, p<0.001), and Medicaid (HR 1.19, 95% CI 1.09 to 1.30, p<0.001) or uninsured status (HR 1.23, 95% CI 1.05 to 1.44, p<0.01) carried a worse prognosis. Single (HR 1.17, 95% CI 1.08 to 1.26, p<0.001), divorced (HR 1.14, 95% CI 1.04 to 1.25, p<0.01), and widowed (HR 1.16, 95% CI 1.06 to 1.26, p<0.001) patients had decreased survival. CONCLUSION Married patients with ovarian cancer were more likely to undergo chemotherapy with better survival rates. Black, uninsured, or patients with Medicaid insurance had poorer outcomes.

Abstract
Background: Black women have greater than a three-fold risk of pregnancy-associated death compared to White women; cardiomyopathy is a leading cause of maternal mortality.Objectives: This study examined racial disparities in health outcomes among women with peripartum cardiomyopathy.Study design: Retrospective cohort of women with peripartum cardiomyopathy per the National Heart, Lung, and Blood Institute definition from January 2000 to November 2017 from a single referral center. Selected health outcomes among Black and White women were compared; primary outcome was ejection fraction at diagnosis. Secondary outcomes included cardiovascular outcomes, markers of maternal morbidity, resource utilization, and subsequent pregnancy outcomes.Results: Ninety-five women met inclusion criteria: 48% Black, 52% White. Nearly all peripartum cardiomyopathy diagnoses were postpartum (95.4% Black, 93% White, p=.11). Ejection fraction at diagnosis was not different between Black and White women (26.8 ± 12.5 vs. 28.7 ± 9.9, p=.41). Though non-significant, fewer Black women had myocardial recovery to EF ≥55% (35 vs. 53%, p=.07); however, 11 (24%) of Black women vs. 1 (2%) White woman had an ejection fraction ≤35% at 6-12 months postpartum (p<.01). More Black women underwent implantable cardioverter defibrillator placement: n = 15 (33%) vs. n = 7 (14%), p=.03. Eight women (8.4%) died in the study period, not different by race (p=.48). Black women had higher rates of healthcare utilization. In the subsequent pregnancy, Black women had a lower initial ejection fraction (40 vs. 55%, p=.007) and were less likely to recover postpartum (37.5 vs. 55%, p=.02).Conclusions: Black and White women have similar mean ejection fraction at diagnosis of peripartum cardiomyopathy, but Black women have more severe left ventricular systolic dysfunction leading to worse outcomes, increased resource use, and lower ejection fraction entering the subsequent pregnancy.

Abstract
OBJECTIVES It is important to develop effective therapies in minorities to ensure equity in cancer care. Underrepresentation of minorities in early phase trials may cause therapies that are effective only in majority populations. We evaluated minority participation in gynecologic oncology phase 1 clinical trials. METHODS In peer-reviewed published articles of gynecologic oncology phase 1 clinical trials from years 1985 to 2018, we manually abstracted racial distribution of enrolled participants, cancer type, and year published. We calculated expected and observed ratios of racial participation on the basis of age-adjusted cancer incidence for race from the United States Centers for Disease Control and Prevention. RESULTS We identified 357 articles of phase 1 trials (total, 9492 participants), including 213 articles on ovarian cancer (60%). Racial distribution of participants was available in 84 articles (23%) that included 2483 participants (26%): 1950 white (79%), 140 black (5%), and 393 other participants (16%). Other nonwhite races exceeded black enrollment in 46 of 84 trials (55%) that listed race. Enrollment of black participants was less than expected from disease incidence for ovarian (incidence-to-enrollment ratio, 18.5; P < .001), endometrial (3.6; P < .001), and cervical cancer (6.8; P < .001). No phase 1 study met expected enrollment for black participants. Frequency of black participants decreased 1.8-fold from 1995 to 1999 (8 of 70 participants [11%]) to 2015-2018 (55 of 892 participants [6%]; P < .025). CONCLUSIONS Major racial underrepresentation exists in gynecologic oncology phase 1 clinical trials. Enrollment of more black participants is needed to achieve racial equity.

Abstract
OBJECTIVE Although ovarian cancer is a deadly disease, approximately a third of women survive ≥9 years after diagnosis. The factors associated with achieving long-term survival are not well understood. In this study, data from the Surveillance, Epidemiology, and End Results (SEER) program were used to determine predictors of survival trajectories among women with epithelial ovarian cancer and across histotype (high-grade serous carcinoma (HGSC) and non-HGSC). METHODS Data on 35,868 women diagnosed with epithelial ovarian cancer in 2004-2016 were extracted from SEER. Extended Cox proportional hazards regression was used to estimate overall and histotype-specific associations between patient and tumor characteristics and all-cause mortality within each survival time (t) interval (t < 3, 3 ≤ t < 6, 6 ≤ t < 9, and 9 ≤ t < 13 years). RESULTS Age at diagnosis, marital status, race/ethnicity, stage, and surgery were more strongly associated with mortality in the short-term survival period, and these associations waned with increasing survival time. Exceptions to this pattern were age >70 years at diagnosis, where a high risk of mortality was observed in both the t < 3 and t ≥ 9 year time periods, and non-Hispanic Asian/Pacific Islanders, where a more pronounced inverse association with mortality was observed in t ≥ 9 years after diagnosis. Similar associations were observed for HGSC, although the waning effect was not apparent for most characteristics. Mortality associations for non-HGSC were more pronounced for stage and race/ethnicity, primarily for non-Hispanic Asian/Pacific Islanders. CONCLUSIONS Most patient and tumor characteristics were more strongly associated with mortality in the years following diagnosis, but have declining impact with increasing survival time. Given this waning effect, it is critical to identify factors impacting risk of mortality as ovarian cancer patients advance through the survival trajectory.

Abstract
BACKGROUND Population-based studies of women with epithelial ovarian cancer suggest that black women have worse survival compared to white women. The primary objective of this study was to determine if, at a National Cancer Institute (NCI)-Designated Comprehensive Cancer Center (CCC) serving a diverse racial and socioeconomic population, race is independently associated with differences in survival. METHODS A retrospective review of women with EOC diagnosed between 2004-2009 undergoing treatment with follow-up at our institution was performed. Records were reviewed for demographics, comorbidities (as defined by the Charlson Comorbidity Index (CCI)), tumor characteristics, treatment, progression-free (PFS), and overall survival (OS). Survival was calculated using the Kaplan-Meier method and compared with the log-rank test. Multivariate survival analysis was performed with Cox (proportional hazards) model. RESULTS 367 patients met inclusion criteria. 54 (15%) were black and 308 (84%) were white. Compared to white women, black women had higher BMI, lower rates of optimal surgical cytoreduction, lower rates of intraperitoneal chemotherapy, and higher CCI scores. The median PFS for black and white women were 9.7 and 14.6months, respectively (p=0.033). The median overall survival was 21.7months for black women and 42.6months for white women (p<0.001). On multivariate analysis, black race independently correlated with a worse overall survival (HR 1.61, 95% CI 1.06-2.43). CONCLUSION In this cohort, racial disparities may be due to higher medical comorbidities and lower rates of optimal surgical cytoreduction. After accounting for these differences, race remained an independent predictor of worse overall survival.

Socioeconomic disparities affect survival in malignant ovarian germ cell tumors in AYA population. J Surg Res 2017; 222:180-186.e3.

Abstract
BACKGROUND Malignant ovarian germ cell tumors (MOGCTs) are a rare form of ovarian malignancy. Socioeconomic status (SES) has been shown to affect survival in several gynecologic cancers. We examined whether SES impacted survival in adolescent and young adults (AYAs) with MOGCT. MATERIALS AND METHODS The National Cancer Data Base was used to identify AYAs (aged 15-39 years) with MOGCT from 1998 to 2012. Three SES surrogate variables identified were as follows: insurance type, income quartile, and education quartile. Pooled variance t-tests and chi-square tests were used to compare tumor characteristics, the time from diagnosis to staging/treatment, and clinical outcome variables for each SES surrogate variable, while controlling for age and race/ethnicity in a multivariate model. Kaplan-Meier survival estimates were calculated using the log-rank test. RESULTS A total of 3125 AYAs with MOGCT were identified. Subjects with lower SES measures had higher overall stage and T-stage MOGCTs at presentation. There was no significant difference in the time to staging/treatment, extent of surgery, or use of chemotherapy by SES. Subjects from a lower education background, from a lower income quartile, and without insurance had decreased survival (P ≤ 0.02 for all). Controlling for overall stage and T-stage, the difference in survival was no longer significant. CONCLUSIONS AYAs with MOGCT from lower SES backgrounds presented with more advanced stage disease. Further studies that focus on the underlying reasons for this difference are needed to address these disparities.

Abstract
Ovarian cancer (OC) is the most lethal gynecological malignancy, which disproportionately affects African American (AA) women. Lack of awareness and socioeconomic factors are considered important players in OC racial health disparity, while at the same time, some recent studies have brought focus on the genetic basis of disparity as well. Differential polymorphisms, mutations and expressions of genes have been reported in OC patients of diverse racial and ethnic backgrounds. Combined, it appears that neither genetic nor the socioeconomic factors alone might explain the observed racially disparate health outcomes among OC patients. Rather, a more logical explanation would be the one that takes into consideration the combination and/or the interplay of these factors, perhaps even including some environmental ones. Hence, in this article, we attempt to review the available information on OC racial health disparity, and provide an overview of socioeconomic, environmental and genetic factors, as well as the epigenetic changes that can act as a liaison between the three. A better understanding of these underlying causes will help further research on effective cancer management among diverse patient population and ultimately narrow health disparity gaps.
