Racial disparities in survival of early onset colon cancer (Age<50): A matched NCDB analysis

Sex and Racial/Ethnic Differences in End-of-Life Care in Texan Medicare Colorectal Cancer Decedents

BackgroundThere are known sex and racial/ethnic differences in colorectal cancer care. The purpose of this study is to investigate these differences in end-of-life health care utilization, advance care planning, and associated outcomes among Texan Medicare colorectal cancer decedents.MethodsIn this retrospective case control study, we used the Texas Cancer Registry linked with Medicare data for patients (n = 5757) aged ≥66 years who died 6 months to 5 years after receiving a diagnosis of primary colorectal cancer from 2010-2018. We used chi-square tests, t-tests, or ANOVA as appropriate for outcomes in the last 30 days of life to assess sex and racial/ethnic differences. Multivariable logistic regression models were used to assess differences in the odds of inpatient admission and hospice enrollment.ResultsSignificantly more female decedents were hospice enrolled. Non-Hispanic Black decedents, and to a lesser extent Hispanic decedents, had greater health care utilization, including inpatient stays, and less hospice enrollment compared to non-Hispanic White decedents. Advance care planning was low (≤2.2%) across all groups, with no significant differences. Multivariable logistic regression models showed that female decedents had greater odds of hospice enrollment compared to male decedents, and non-Hispanic Black decedents had greater odds of inpatient stays and decreased odds of hospice enrollment compared to non-Hispanic White decedents.ConclusionSex and racial/ethnic disparities in care highlight opportunities for process and quality improvement and suggest a need for practice changes to improve access to quality end-of-life care. More work is needed to incorporate advance care planning and billing into regular workflows.

Race/Ethnicity and Social Determinants of Health and Their Impact on Receiving Appropriate Chemotherapy for Colon Cancer

INTRODUCTION

Despite the heightened understanding and improved treatment for colorectal cancer in the United States, social determinants of health (SDH) play a significant role in the colorectal cancer outcomes. We sought to investigate the relationship between SDH and appropriate utilization of adjuvant chemotherapy in stage III colon cancer.

METHODS

For this retrospective study, we utilized data from the National Cancer Data Base (NCDB). Descriptive statistics are reported, including means and 95% confidence intervals for continuous variables and frequency and proportions for categorical variables. Univariate hypothesis testing to identify categorical level factors associated with treatment used Wilcoxon rank sum or Kruskal-Wallis tests, with multivariate analyses performed using regression analysis.

RESULTS

Significant differences were as follows: Metro-non-Hispanic White patients received treatment less frequently (69.7%) when compared to Metro-non-Hispanic Black patients (73.4%) (P < .001). Increasing age was a negative predictor of likelihood to receive with those over 65 years old having an 83% decrease in likelihood to receive chemotherapy when compared to those under 65 (P < .001). Medicaid patients were 47% less likely and Medicare patients were 40% less likely to receive chemotherapy when compared to those with private insurance (P < .001). Rural patients were statistically more likely to receive chemotherapy (OR 1.42, 1.32-2.52, P < .001) as were urban patients, (OR 1.26, 1.20-1.31, P < .001) when compared to patients residing in metro areas.

CONCLUSION

Age, living in a Metro area, and government insurance status at diagnosis are negatively correlated with the likelihood of receiving chemotherapy. Race was not associated with differences in receiving chemotherapy.
