Characteristics of Cancer Survivors Living in Poverty in the United States: Results From the 2020 Behavioral Risk Factor Surveillance System Survey

PURPOSE

There has been increasing concern over the high cost of oncology care and its long-lasting impact on the well-being of cancer survivors.

METHODS

We examined characteristics of impoverished cancer survivors in the United States, including their physical and mental health, using data from the 2020 Behavioral Risk Factor Surveillance System. We used binomial logistic regressions for binary outcome variables, and negative binomial regressions for count variables, to estimate the odds ratios (ORs) and incident rate ratios (IRRs) of the physical, mental, and socioeconomic-related health factors for low-income cancer survivors versus higher-income survivors. We compared the ORs and IRRs for low-income cancer survivors with those of higher income cancer survivors.

RESULTS

There was a two-fold increased odds (adjusted OR, 2.33; 95% CI, 1.86 to 2.91) of having fair/poor health for low-income cancer survivors compared with higher-income cancer survivors. There was an almost two-fold increased odds (adjusted OR, 1.97; 95% CI, 1.50 to 2.59) of not being able to see a doctor among low-income cancer survivors, and a 42% lower odds (adjusted OR, 0.58; 95% CI, 0.39 to 0.86) of having health insurance coverage for low-income cancer survivors compared with higher-income survivors. Incidence rate ratios for physical (IRR, 1.52; 95% CI, 1.31 to 1.75) and mental (IRR, 1.53; 95% CI, 1.26 to 1.86) unhealthy days were significantly higher among low-income cancer survivors compared with nonpoor cancer survivors.

CONCLUSION

Strategies are available to ameliorate financial hardship at multiple levels. Implementation of these strategies is urgently needed.

Ovarian Cancer Epidemiology, Healthcare Access and Disparities (ORCHiD): methodology for a population-based study of black, Hispanic and white patients with ovarian cancer

INTRODUCTION

Less than 40% of patients with ovarian cancer (OC) in the USA receive stage-appropriate guideline-adherent surgery and chemotherapy. Black patients with cancer report greater depression, pain and fatigue than white patients. Lack of access to healthcare likely contributes to low treatment rates and racial differences in outcomes. The Ovarian Cancer Epidemiology, Healthcare Access and Disparities study aims to characterise healthcare access (HCA) across five specific dimensions-Availability, Affordability, Accessibility, Accommodation and Acceptability-among black, Hispanic and white patients with OC, evaluate the impact of HCA on quality of treatment, supportive care and survival, and explore biological mechanisms that may contribute to OC disparities.

METHODS AND ANALYSIS

We will use the Surveillance Epidemiology and Ends Results dataset linked with Medicare claims data from 9744 patients with OC ages 65 years and older. We will recruit 1641 patients with OC (413 black, 299 Hispanic and 929 white) from cancer registries in nine US states. We will examine HCA dimensions in relation to three main outcomes: (1) receipt of quality, guideline adherent initial treatment and supportive care, (2) quality of life based on patient-reported outcomes and (3) survival. We will obtain saliva and vaginal microbiome samples to examine prognostic biomarkers. We will use hierarchical regression models to estimate the impact of HCA dimensions across patient, neighbourhood, provider and hospital levels, with random effects to account for clustering. Multilevel structural equation models will estimate the total, direct and indirect effects of race on treatment mediated through HCA dimensions.

ETHICS AND DISSEMINATION

Result dissemination will occur through presentations at national meetings and in collaboration with collaborators, community partners and colleagues across othercancer centres. We will disclose findings to key stakeholders, including scientists, providers and community members. This study has been approved by the Duke Institutional Review Board (Pro00101872). Safety considerations include protection of patient privacy. All disseminated data will be deidentified and summarised.

Sistas Inspiring Sistas Through Activity and Support (SISTAS): Study Design and Demographics of Participants

Introduction

Recruiting racial, ethnic, and other underserved minorities into conventional clinic-based and other trials is known to be challenging. The Sistas Inspiring Sistas Through Activity and Support (SISTAS) Program was a one-year randomized controlled trial (RCT) to promote physical activity and healthy eating among AA women in SC to reduce inflammatory biomarkers, which are linked to increased breast cancer (BrCa) risk and mortality. This study describes the development, recruitment, and implementation of the SISTAS clinical trial and provides baseline characteristics of the study participants.

Methods

SISTAS was developed using community-based participatory research (CBPR) approaches. At baseline, study participants completed assessments and underwent clinical measurements and blood draws to measure C-reactive protein (CRP) and interleukin-6 (IL-6). Participants randomized to the intervention received 12 weekly classes followed by nine monthly booster sessions. Post-intervention measurements were assessed at 12-week and 12-month follow-ups.

Results

We recruited a total of 337 women who tended to: be middle-aged (mean age 48.2 years); have some college education; be employed full-time; have Medicare as their primary insurance; be non-smokers; and perceive their personal health as good. On average, the women were pre-hypertensive at baseline (mean systolic blood pressure = 133.9 mm Hg; mean diastolic blood pressure = 84.0 mm Hg) and morbidly obese (mean BMI >40.0 kg/m²); the mean fat mass and fat-free mass among participants were 106.4 lb and 121.0 lb, respectively.

Conclusion

The SISTAS RCT addresses some of the gaps in the literature with respect to CBPR interventions targeting AA women, such as implementing diet and physical activity in CBPR-based studies to decrease BrCa risk.
