Abstract
INTRODUCTION Racial and ethnic disparities in gynecologic cancer care have been documented. Treatment at academic facilities is associated with improved survival, yet no study has examined independent associations between race and ethnicity with facility type among gynecologic cancer patients. MATERIALS & METHODS We used the National Cancer Database and identified 484,455 gynecologic cancer (cervix, ovarian, uterine) patients diagnosed between 2004 and 2020. Facility type was dichotomized as academic vs. non-academic, and we used logistic regression to estimate multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) between race and ethnicity and facility type. Secondarily, we examined joint effects of race and ethnicity and facility type on overall survival using Cox proportional hazards regression. RESULTS We observed higher odds of treatment at academic (vs. non-academic) facilities among American Indian/Alaska Native (OR = 1.42, 95% CI = 1.28-1.57), Asian (OR = 1.64, 95% CI = 1.59-1.70), Black (OR = 1.69, 95% CI = 1.65-1.72), Hispanic (OR = 1.70, 95% CI = 1.66-1.75), Native Hawaiian/Pacific Islander (OR = 1.74, 95% CI = 1.57-1.93), and other race (OR = 1.29, 95% CI = 1.20-1.40) patients compared with White patients. In the joint effects survival analysis with White, academic facility-treated patients as the reference group, Asian, Hispanic, and other race patients treated at academic or non-academic facilities had improved overall survival. Conversely, Black patients treated at academic facilities [Hazard Ratio (HR) = 1.10, 95% CI = 1.07-1.12] or non-academic facilities (HR = 1.19, 95% CI = 1.16-1.21) had worse survival. DISCUSSION Minoritized gynecologic cancer patients were more likely than White patients to receive treatment at academic facilities. Importantly, survival outcomes among patients receiving care at academic institutions differed by race, requiring research to investigate intra-facility survival disparities.

[PMID: 38460831 DOI: 10.1016/j.ajog.2024.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 03/01/2024] [Accepted: 03/04/2024] [Indexed: 03/11/2024]
Abstract
BACKGROUND Racial and ethnic differences in early death after cancer diagnosis have not been well studied in gynecologic malignancy. OBJECTIVE This study aimed to assess population-level trends and characteristics of early death among patients with gynecologic malignancy based on race and ethnicity in the United States. STUDY DESIGN The National Cancer Institute's Surveillance, Epidemiology, and End Results Program was queried to examine 461,300 patients with gynecologic malignancies from 2000 to 2020, including uterine (n=242,709), tubo-ovarian (n=119,989), cervical (n=68,768), vulvar (n=22,991), and vaginal (n=6843) cancers. Early death, defined as a mortality event within 2 months of the index cancer diagnosis, was evaluated per race and ethnicity. RESULTS At the cohort level, early death occurred in 21,569 patients (4.7%), including 10.5%, 5.5%, 2.9%, 2.5%, and 2.4% for tubo-ovarian, vaginal, cervical, uterine, and vulvar cancers, respectively (P<.001). In a race- and ethnicity-specific analysis, non-Hispanic Black patients with tubo-ovarian cancer had the highest early death rate (14.5%). Early death racial and ethnic differences were the largest in tubo-ovarian cancer (6.4% for Asian vs 14.5% for non-Hispanic Black), followed by uterine (1.6% for Asian vs 4.9% for non-Hispanic Black) and cervical (1.8% for Hispanic vs 3.8% to non-Hispanic Black) cancers (all, P<.001). In tubo-ovarian cancer, the early death rate decreased over time by 33% in non-Hispanic Black patients from 17.4% to 11.8% (adjusted odds ratio, 0.67; 95% confidence interval, 0.53-0.85) and 23% in non-Hispanic White patients from 12.3% to 9.5% (adjusted odds ratio, 0.77; 95% confidence interval, 0.71-0.85), respectively. The early death between-group difference diminished only modestly (12.3% vs 17.4% for 2000-2002 [adjusted odds ratio for non-Hispanic White vs non-Hispanic Black, 0.54; 95% confidence interval, 0.45-0.65] and 9.5% vs 11.8% for 2018-2020 [adjusted odds ratio, 0.65; 95% confidence interval, 0.54-0.78]). CONCLUSION Overall, approximately 5% of patients with gynecologic malignancy died within the first 2 months from cancer diagnosis, and the early death rate exceeded 10% in non-Hispanic Black individuals with tubo-ovarian cancer. Although improving early death rates is encouraging, the difference among racial and ethnic groups remains significant, calling for further evaluation.

Surg Open Sci 2024; 20:101-105. [PMID: 39021616 PMCID: PMC11252929 DOI: 10.1016/j.sopen.2024.06.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Accepted: 06/12/2024] [Indexed: 07/20/2024] Open
Abstract
Background Multiagent neoadjuvant chemotherapy (NAT) has been linked with improved survival for locally advanced (LA) or borderline resectable (BR) pancreatic ductal adenocarcinoma (PDAC). However, the existence of disparities in its utilization remains to be elucidated. Methods All adults with PDAC were tabulated from the 2011-2017 Nationwide Cancer Database. Tumor vascular involvement was determined using the clinical T stage and CS_EXTENSION variables. The significance of temporal trends was calculated using Cuzick's non-parametric test. A Cox proportional hazard model was used to assess the impact of NAT utilization on hazard of two-year mortality. A logistic regression model was developed to determine factors associated with receipt of NAT. Results Of 3811 patients meeting inclusion criteria, 50.8 % received NAT. NAT utilization significantly increased over the study period, from 31.7 % in 2011 to 81.1 % in 2017 (p < 0.001). NAT was associated with significantly reduced two-year mortality (Hazards Ratio 0.34, 95 % Confidence Interval [CI] 0.18-0.67).After adjustment, younger (Adjusted Odds Ratio [AOR] 0.97/year, CI 0.96-0.98) and Black (AOR 0.65, CI 0.48-0.89; ref: White) patients demonstrated reduced odds of NAT. Furthermore, patients with Medicare (AOR 0.73, CI 0.59-0.90; ref: Private) or Medicaid insurance (AOR 0.67, CI 0.46-0.97; ref: Private) had lower odds of NAT, as did those treated at non-academic institutions (Community: AOR 0.42, CI 0.35-0.52, Integrated: 0.68, CI 0.54-0.85) or in the lowest education quartile (AOR 0.52, CI 0.29-0.95; ref: Highest). Conclusions We identified increasing utilization of NAT for BR/LA pancreatic adenocarcinoma. Despite being linked with significantly reduced two-year mortality, socioeconomic disparities affect odds of NAT.

Racial and socioeconomic disparities in survival among women with advanced-stage ovarian cancer who received systemic therapy. Cancer Causes Control 2024; 35:487-496. [PMID: 37874478 PMCID: PMC10838826 DOI: 10.1007/s10552-023-01810-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 09/29/2023] [Indexed: 10/25/2023]
Abstract
PURPOSE The purpose of this study was to assess the association between race/ethnicity and all-cause mortality among women with advanced-stage ovarian cancer who received systemic therapy. METHODS We analyzed data from the National Cancer Database on women diagnosed with advanced-stage ovarian cancer from 2004 to 2015 who received systemic therapy. Race/ethnicity was categorized as Non-Hispanic (NH) White, NH-Black, Hispanic, NH-Asian/Pacific Islander, and Other. Income and education were combined to form a composite measure of socioeconomic status (SES) and categorized into low-, mid-, and high-SES. Multivariable Cox proportional hazards models were used to assess whether race/ethnicity was associated with the risk of death after adjusting for sociodemographic, clinical, and treatment factors. Additionally, subgroup analyses were conducted by SES, age, and surgery receipt. RESULTS The study population comprised 53,367 women (52.4% ages ≥ 65 years, 82% NH-White, 8.7% NH-Black, 5.7% Hispanic, and 2.7% NH-Asian/Pacific Islander) in the analysis. After adjusting for covariates, the NH-Black race was associated with a higher risk of death versus NH-White race (aHR: 1.12; 95% CI: 1.07,1.18), while Hispanic ethnicity was associated with a lower risk of death compared to NH-White women (aHR: 0.87; 95% CI: 0.80, 0.95). Furthermore, NH-Black women versus NH-White women had an increased risk of mortality among those with low-SES characteristics (aHR:1.12; 95% CI:1.03-1.22) and mid-SES groups (aHR: 1.13; 95% CI:1.05-1.21). CONCLUSIONS Among women with advanced-stage ovarian cancer who received systemic therapy, NH-Black women experienced poorer survival compared to NH-White women. Future studies should be directed to identify drivers of ovarian cancer disparities, particularly racial differences in treatment response and surveillance.

Abstract
PURPOSE OF REVIEW Ovarian cancer ranks fifth in mortality among women with cancer and accounts for more death compared to any other gynecological cancers. This review summarizes the most recent literature on disparities in ovarian cancer as well as within recent clinical trials. RECENT FINDINGS Recent studies have identified a notable disparity in genetic testing utilization, disease stage at the time of diagnosis, and adherence to treatment guidelines between Black women and their White counterparts, ultimately leading to increased mortality rates among Black women from ovarian cancer. Additionally, there is an underreporting of race in clinical trials and those that do report race demonstrate significant racial disparities within trial participants with the majority of participants being White. SUMMARY It is imperative that we address the significant racial disparities within ovarian cancer and clinical trials to establish a framework of equitable healthcare provision. Multiple determinants, such as implicit bias, provider mistrust, accessibility hurdles, and socioeconomic influences, appear to contribute to the current disparities faced by women of color. Further investigation is warranted, encompassing a deeper understanding of diverse patient perspectives and identifying barriers to receiving optimal care and participating in clinical trials.

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.
