Race and socioeconomic status interact with HPV to influence survival disparities in oropharyngeal squamous cell carcinoma.

ABSTRACT:

Background

HPV-related oropharyngeal squamous cell carcinoma (OPSCC) is associated with a favorable prognosis, yet patients of color and low socioeconomic status (SES) continue to experience inferior outcomes. We aim to understand how the emergence of HPV has impacted race and SES survival disparities in OPSCC.

Methods

A retrospective cohort of 18,362 OPSCC cases from 2010 to 2017 was assembled using the SEER (Surveillance, Epidemiology, and End Results) database. Cox proportional regression and Fine and Gray regression models were used to calculate hazard ratios (HRs) adjusting for race, SES, age, subsite, stage, and treatment.

Results

Black patients had lower overall survival than patients of other races in HPV-positive and HPV-negative OPSCC (HR 1.31, 95% CI 1.13-1.53 and HR 1.23, 95% CI 1.09-1.39, respectively). Higher SES was associated with improved survival in all patients. Race had a diminished association with survival among high SES patients. Low SES Black patients had considerably worse survival than low SES patients of other races.

Conclusion

Race and SES interact variably across cohorts. High SES was protective of the negative effects of race, although there remains a disparity in outcomes among Black and non-Black patients, even in high SES populations. The persistence of survival disparities suggests that the HPV epidemic has not improved outcomes equally across all demographic groups.

Project description:BackgroundThe relationship between racial and socioeconomic status (SES) disparities and the quality of epithelial ovarian cancer care and survival outcome are unclear.MethodsA population-based analysis of National Cancer Data Base (NCDB) records for invasive primary epithelial ovarian cancer diagnosed in the period from 1998 to 2002 was done using data from patients classified as white or black. Adherence to National Comprehensive Cancer Network (NCCN) guideline care was defined by stage-appropriate surgical procedures and recommended chemotherapy. The main outcome measures were differences in adherence to NCCN guidelines and overall survival according to race and SES and were analyzed using binomial logistic regression and multilevel survival analysis.ResultsA total of 47 160 patients (white = 43 995; black = 3165) were identified. Non-NCCN-guideline-adherent care was an independent predictor of inferior overall survival (hazard ratio [HR] = 1.43, 95% confidence interval [CI] = 1.38 to 1.47). Demographic characteristics independently associated with a higher likelihood of not receiving NCCN guideline-adherent care were black race (odds ratio [OR] = 1.36, 95% CI = 1.25 to 1.48), Medicare payer status (OR = 1.20, 95% CI = 1.12 to 1.28), and not insured payer status (OR = 1.33, 95% CI = 1.19 to 1.49). After controlling for disease and treatment-related variables, independent racial and SES predictors of survival were black race (HR = 1.29, 95% CI = 1.22 to 1.36), Medicaid payer status (HR = 1.29, 95% CI = 1.20 to 1.38), not insured payer status (HR = 1.32, 95% CI = 1.20 to 1.44), and median household income less than $35 000 (HR = 1.06, 95% CI = 1.02 to 1.11).ConclusionsThese data highlight statistically and clinically significant disparities in the quality of ovarian cancer care and overall survival, independent of NCCN guidelines, along racial and SES parameters. Increased efforts are needed to more precisely define the patient, provider, health-care system, and societal factors leading to these observed disparities and guide targeted interventions.

Project description:Patients with human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV-OPSCC) have a favorable prognosis and excellent overall survival (OS), and studies have demonstrated these findings in cohorts of predominantly White patients. Racial/ethnic (R/E) minorities, particularly Black patients, with head and neck squamous cell carcinoma (HNSCC) have worse survival outcomes compared with White patients. In this study, we aimed to determine if Black patients with HPV-OPSCC have a similar favorable prognosis to the White population. This was a population-based retrospective cohort study that analyzed HNSCC patients using the National Cancer Database from 2010 to 2016. We identified patients with Stage I-IV HPV- OPSCC who were treated with radiation, surgery, chemotherapy, or a combination of modalities. Patient outcomes were stratified by R/E groups including White Versus Black patients. The main outcome in this study was OS. Analyses for proportions of categorical variables were performed using a χ2 or Fisher's exact test. Univariate and multivariate time-to-event survival analyses were performed using Kaplan-Meier product limit estimates and log-rank test to test the differences between strata. A Cox proportional hazards regression model was used to assess the association between covariates and risk of death (OS). We identified 9256 OPSCC patients who met inclusion criteria and were treated between 2010 and 2016, of which 7912 were White (85.5%) and 1344 were Black (14.5%). A total of 1727 were HPV-OPSCC, of which 1598 were White (92.5%) and 129 (7.5%) were Black. By race, the 5-year OS for White versus Black OPSCC patients was 42% versus 23%, respectively (log-rank, p < 0.0001). Among HPV-positive OPSCC patients, the 5-year OS for White versus Black patients was 65% versus 39% (log-rank, p < 0.0001). Among HPV-negative patients, the 5-year OS for White versus Black patients was 36% versus 13% (log-rank, p < 0.0001). On multivariate analysis, after accounting for age, sex, insurance status, income, Charlson-Deyo score, receipt of surgery, distance from facility, and total treatment time, Black race trended toward, but was not associated with worse survival. Hazard ratio (HR:1.24, 95% confidence interval [CI] 0.85-1.81, p = 0.255). This national cohort study of OPSCC patients demonstrates that Black patients with HPV-OPSCC have a poor prognosis and OS similar to HPV-negative White patients. This may be partly due to socioeconomic barriers such as insurance and income. Further work is needed to better understand the specific drivers of inferior survival outcomes in this specific patient population.

Project description:ObjectivesThis study sought to describe the health status of outpatients with heart failure and reduced ejection fraction (HFrEF) by sex, race/ethnicity, and socioeconomic status (SES).BackgroundAlthough a primary goal in treating patients with HFrEF is to optimize health status, whether disparities by sex, race/ethnicity, and SES exist is unknown.MethodsIn the CHAMP-HF (Change the Management of Patients with Heart Failure) registry, the associations among sex, race, and SES and health status, as measured by the Kansas City Cardiomyopathy Questionnaire-overall summary (KCCQ-os) score (range 0 to 100; higher scores indicate better health status) was compared among 3,494 patients from 140 U.S. clinics. SES was categorized by total household income. Hierarchical multivariate linear regression estimated differences in KCCQ-os score after adjusting for 31 patient characteristics and 10 medications.ResultsOverall mean KCCQ-os scores were 64.2 ± 24.0 but lower for women (29% of sample; 60.3 ± 24.0 vs. 65.9 ± 24.0, respectively; p < 0.001), for blacks (60.5 ± 25.0 vs. 64.9 ± 23.0, respectively; p < 0.001), for Hispanics (59.1 ± 21.0 vs. 64.9 ± 23.0, respectively; p < 0.001), and for those with the lowest income (<$25,000; mean: 57.1 vs. 63.1 to 74.7 for other income categories; p < 0.001). Fully adjusted KCCQ-os scores were 2.2 points lower for women (95% confidence interval [CI]: -3.8 to -0.6; p = 0.007), no different for blacks (p = 0.74), 4.0 points lower for Hispanics (95% CI: -6.6 to -1.3; p = 0.003), and lowest in the poorest patients (4.7 points lower than those with the highest income (95% CI: 0.1 to 9.2; p = 0.045; p for trend = 0.003).ConclusionsAmong outpatients with HFrEF, women, blacks, Hispanics, and poorer patients had worse health status, which remained significant for women, Hispanics, and poorer patients in fully adjusted analyses. This suggests an opportunity to further optimize treatment to reduce these observed disparities.

Project description:BackgroundHead and Neck Cancer (HNC) is a major cause of cancer morbidity and mortality in the United States, but the burden is not evenly distributed. Rural and racial disparities are obvious across the HNC continuum. Most HNC disparities research have emphasized individual factors perpetuating rural and racial disparities, ignoring the role of community-level factors.MethodsWe analyzed data from the Surveillance Epidemiology and End Results (SEER) program's "Specialized HNC-Human Papillomavirus (HPV) Census-Tract SES" datafile (2010-2016). In addition to cancer patient characteristics, this data includes a socioeconomic status (SES) quintile based on the patient's census-tract. Our outcome variables included whether the HNC patient 1) was diagnosed at a distant stage, 2) received initial treatment two or more months after diagnosis, 3) received radiation therapy, 4) survived two years after diagnosis. We tested for differences across SES quintiles, in the full sample and then within rural/racial categories. We then tested for differences between each rural/racial category conditional on SES quintile.ResultsFor both HPV(-) and HPV + HNCs, patients in higher SES census-tracts have 8-10% lower rates of distant stage diagnoses and delayed treatment initiation, and 12.0-14.5% higher survival rates than patients in lower SES census-tracts. Radiation treatment only varied across SES quintiles in HPV + HNC patients. We find little evidence of rural-urban differences within each socioeconomic quintile. However, within lower SES quintiles, we found significant racial disparities in delayed detection and treatment. These differences were largest in the lowest SES quintile, as non-Hispanic Black patients reported 10-11% higher rates of delayed detection and treatment initiation than non-Hispanic White patients.ConclusionsOur research illustrates the value and constraints in leveraging community-level factors in health disparities research that can ultimately assist in designing effective policies that address and achieve rural and racial cancer equity.
