Association Between Marital Status and Racial Disparities in Esophageal Cancer Care

The Impact of Race and Ethnicity on Location and Delivery of Palliative Radiotherapy

OBJECTIVES

Among patients that underwent palliative RT (pRT) at a single institution, we evaluated whether differences exist across race and ethnicity in location of pRT consultation and delivery of pRT.

METHODS

This retrospective study included cancer patients aged 18 years or older who received pRT between 10/2021 and 10/2022. Logistic regression models were used to examine univariable (UVA) and multivariable (MVA) associations between race and pRT consult in the inpatient (vs. outpatient) setting. A subset analysis of quality metrics for pRT delivery was limited to patients who had outpatient consults for pain.

RESULTS

Four hundred forty patients underwent 548 pRT consults (104 inpatient and 444 outpatient) followed by a course of pRT. Most patients were male (58.2%), White non-Hispanic (WNH) (72.6%), and English-speaking (92.9%). On MVA adjusting for histology, language, and insurance type, consults for Black/African American (BAA) patients had 2.92 higher odds of being performed in the inpatient setting compared with consults for WNH patients (95% CI: 1.28-6.70, P=0.011), although the global P-value was P=0.217. Among 290 outpatient consults for painful lesions, no differences in time to pRT start (global P=0.84), number of prescribed fractions of RT (global P=0.94), or new prescriptions for opioids (global P=0.69) were noted by race and ethnicity.

CONCLUSIONS

In this study, BAA race was associated with the location of pRT consultation, but no discernible differences were noted regarding the outpatient delivery of pRT for pain. These findings support the importance of inpatient pRT programs to ensure equitable access. More research is needed to understand barriers to outpatient consult.

Racial and social-economic inequalities in systemic chemotherapy use among adult glioblastoma patients following surgery and radiotherapy

Not all patients with glioblastoma multiforme (GBM) eligible for systemic chemotherapy after upfront surgery and radiotherapy finally receive it. The information on patients with GBM was retrieved from the surveillance, epidemiology, and end results database. Patients who underwent upfront surgery or biopsy and external beam radiotherapy between 2010 and 2019 were eligible for systemic chemotherapy. The available patient and tumor characteristics were assessed using multivariable logistic regression and chi-squared test. Out of the 16,682 patients eligible, 92.1% underwent systemic chemotherapy. The characteristics linked to the lowest systemic chemotherapy utilization included tumors of the brain stem/cerebellum (P = 0.01), former years of diagnosis (P = 0.001), ≥ 80 years of age (P < 0.001), Hispanic, Non-Hispanic Asian, Pacific Islander, or Black race (P < 0.001), non-partnered status (P < 0.001), and low median household income (P = 0.006). Primary tumor site, year of diagnosis, age, race, partnered status, and median household income correlated with the omission of systemic chemotherapy in GBM in adult patients.

Racial Disparity in Esophageal Squamous Cell Carcinoma Treatment and Survival in the United States

INTRODUCTION

Esophageal squamous cell carcinoma (ESCC) has a higher incidence and prevalence than esophageal adenocarcinoma among Black individuals in the United States. Black individuals have lower ESCC survival. These racial disparities have not been thoroughly investigated. We examined the disparity in treatment and survival stratified by ESCC stage at diagnosis.

METHODS

The Surveillance, Epidemiology, and End Results database was queried to identify patients with ESCC between 2000 and 2019. The identified cohort was divided into subgroups by race. Patient and cancer characteristics, treatment received, and survival rates were compared across the racial subgroups.

RESULTS

A total of 23,768 patients with ESCC were identified. Compared with White individuals, Black individuals were younger and had more distant disease during diagnosis (distant disease: 26.7% vs 23.8%, P < 0.001). Black individuals had lower age-standardized 5-year survival for localized (survival % [95% confidence interval]: 19.3% [16-22.8] vs 27.6% [25.1-30.2]), regional (14.3% [12-16.7] vs 21.1% [19.6-22.7]), and distant (2.9% [1.9-4.1] vs 6.5% [5.5-7.5]) disease. Black individuals were less likely to receive chemotherapy (54.7% vs 57.5%, P = 0.001), radiation (58.5% vs 60.4%, P = 0.03), and surgery (11.4% vs 16.3%, P < 0.0001).

DISCUSSION

Black individuals with ESCC have a lower survival rate than White individuals. This could be related to presenting at a later stage but also disparities in which treatments they receive even among individuals with the same stage of disease. To what extent these disparities in receipt of treatment is due to structural racism, social determinants of health, implicit bias, or patient preferences deserves further study.

Increased Variation in Esophageal Cancer Treatment and Geographic Healthcare Disparity in Michigan

BACKGROUND

Regional variation in complex healthcare is shown to negatively impact health outcomes. We sought to characterize geographic variance in esophageal cancer operation in Michigan.

STUDY DESIGN

Data for patients with locoregional esophageal cancer from the Michigan Cancer Surveillance Program from 2000 to 2013 was analyzed. We reviewed the incidence of esophageal cancer by county and region, and those with locoregional disease receiving an esophagectomy. Counties were aggregated into existing state-level "urban vs rural" designations, regions were aggregated using the Michigan Economic Recovery Council designations, and data was analyzed with ANOVA, F-test, and chi-square test.

RESULTS

Of the 8,664 patients with locoregional disease, 2,370 (27.4%) were treated with operation. Men were significantly more likely to receive esophagectomy than women (p < 0.001). Likewise, White, insured, and rural patients were more likely than non-White (p < 0.001), non-insured (p = 0.004), and urban patients (p < 0.001), respectively. There were 8 regions and 83 counties, with 61 considered rural and 22 urban. Region 1 (Detroit metro area, southeast) comprises the largest urban and suburban populations; with 4 major hospital systems it was considered the baseline standard for access to care. Regions 2 (west; p = 0.011), 3 (southwest; p = 0.024), 4 (east central; p = 0.012), 6 (northern Lower Peninsula; p = 0.008), and 8 (Upper Peninsula; p < 0.001) all had statistically significant greater variance in annual rates of operation compared with region 1. Region 8 had the largest variance and was the most rural and furthest from region 1. The variance in operation rate between urban and rural differed significantly (p = 0.005).

CONCLUSIONS

A significant increase in variation of care was found in rural vs urban counties, as well as in regions distant to larger hospital systems. Those of male sex, White race, rural residence, and those with health insurance were significantly more likely to receive operation.

Sex differences in treatment allocation and survival of potentially curable gastroesophageal cancer: A population-based study

BACKGROUND

Although curative treatment options are identical for male and female gastroesophageal cancer patients, access to care and survival may vary. This study aimed to compare treatment allocation and survival between male and female patients with potentially curable gastroesophageal cancer.

METHODS

Nationwide cohort study including all patients with potentially curable gastroesophageal squamous cell or adenocarcinoma diagnosed between 2006 and 2018 registered in the Netherlands Cancer Registry. The main outcome, treatment allocation, was compared between male and female patients with oesophageal adenocarcinoma (EAC), oesophageal squamous cell carcinoma (ESCC), and gastric adenocarcinoma (GAC). Additionally, 5-year relative survival with relative excess risk (RER), that is, adjusted for the normal life expectancy, was compared.

RESULTS

Among 27,496 patients (68.8% men), most were allocated to curative treatment (62.8%), although rates dropped to 45.6%>70 years. Curative treatment rates were comparable among younger male and female patients (≤70 years) with gastroesophageal adenocarcinoma, while older females with EAC were less frequently allocated to curative treatment than males (OR = 0.85, 95% confidence interval [CI] 0.73-0.99). For those allocated to curative treatment, relative survival was superior for female patients with EAC (RER = 0.88, 95% CI 0.80-0.96) and ESCC (RER = 0.82, 95% CI 0.75-0.91), and comparable for males and females with GAC (RER = 1.02, 95% CI 0.94-1.11).

CONCLUSIONS

While curative treatment rates were comparable between younger male and female patients with gastroesophageal adenocarcinoma, treatment disparities were present between older patients. When treated, the survival of females with EAC and ESCC was superior to males. The treatment and survival gaps between male and female patients with gastroesophageal cancer warrant further exploration and could potentially improve treatment strategies and survival.

Equity in adjuvant radiotherapy utilization in locally advanced head and neck cancer: A SEER-data based study

BACKGROUND

Not all patients with locally advanced head and neck cancer (HNC) who are eligible for adjuvant radiotherapy (RT) following upfront surgery appear to receive it.

METHODS

Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Selected patients from 2009 to 2018 had locally advanced HNC, underwent upfront surgery, and were eligible for adjuvant RT. Multivariable logistic regression and chi-squared test were used to analyze available patient and tumor characteristics.

RESULTS

Of 12 549 patients, 84.5% underwent adjuvant RT, 15.5% did not. Characteristics associated with lowest adjuvant RT utilization included cancers of the larynx (p < 0.0001) and gingivae (p < 0.0001), age 80 and above (p < 0.0001), unpartnered status (p < 0.0001), and residence within a nonmetropolitan area (p < 0.0024).

CONCLUSIONS

Tumor subsite, age, partnered status, and rural/urban residence correlate with omission of adjuvant RT in locally advanced HNC.

A narrative review of socioeconomic disparities in the treatment of esophageal cancer

The persistent challenges of disparities in healthcare have led to significantly distinct outcomes among patients from different racial, ethnic, and underserved populations. Esophageal Cancer, not unlike other surgical diseases, has seen significant disparities in care. Esophageal cancer is currently the 6th leading cause of death from cancer and the 8th most common cancer in the world. Surgical disparities in the care of patients with Esophageal Cancer have been described in the literature, with a prevailing theme associating minority status with worse outcomes. The goal of this review is to provide an updated account of the literature on disparities in Esophageal Cancer presentation and treatment. We will approach this task through a conceptual framework that highlights the five main themes of surgical disparities: patient-level factors, provider-level factors, system and access issues, clinical care and quality, and postoperative outcomes, care and rehabilitation. All five categories play a complex role in the delivery of high-quality, equitable care for patients with Esophageal Cancer. While describing disparities in care is the first step to correcting them, moving forward, we should focus on developing effective interventions to mitigate disparities, policies linking disparities to quality-of-care metrics, and delivery system change to enable minority patients to more easily access high volume centers.

Influence of Caregiver Presence During Physician Office Visits on Patients Undergoing Chemoradiation Therapy for Esophageal Cancer

Purpose

Although the association of marital status with outcomes for patients with cancer has been widely studied, the mechanisms underpinning the protective effect of marriage are still not fully understood. The social support that marriage imparts is often discussed as an explanation for why patients with cancer who are married have better outcomes. Social support has been difficult to objectively quantify. Accompaniment of the patient at physician visits may be more meaningful than marital status itself. This study investigated the effect of caregiver presence at physician visits on treatment tolerance and outcome in patients undergoing chemoradiation therapy (CRT) for esophageal cancer.

Methods and Materials

Patients who received a diagnosis of esophageal cancer who underwent CRT from January 1, 2005, to January 1, 2016, as part of their curative-intent management were retrospectively reviewed. Data collected included the patients’ marital status, caregiver presence at each physician visit, baseline performance status, serum albumin values and leukocyte values throughout treatment, patient weight values throughout treatment, tumor response to therapy, and overall survival. Patients were divided into 2 groups based on frequency of caregiver presence at physician visits (<50% or ≥50% of visits). Using χ² tests, Wilcoxon rank sum tests, and log-rank tests, the patients’ characteristics, treatment tolerance and treatment outcome, and overall survival, respectively, were compared.

Results

In total, 35 of 59 patients were defined as having frequent caregiver presence at physician visits (≥50% of all documented visits), whereas 24 patients were categorized as having infrequent caregiver accompaniment. No significant difference in performance status or weight loss before the diagnosis of esophageal cancer was found. Patients who had frequent caregiver presence at physician visits maintained body weight better than those who had infrequent caregiver presence (median weight loss of 2.7 kg compared with 4.9 kg; P = .04). There was no difference in overall survival between the 2 groups.

Conclusions

Although patients with esophageal cancer undergoing CRT who had frequent caregiver presence at physician visits were not found to have an overall survival benefit, they had less weight loss, which may confer favorable treatment tolerance and maintenance of nutritional status during cancer treatment.
