Key PointsQuestion
Among patients with cancer and COVID-19, do non-Hispanic Black patients have more severe COVID-19 at presentation and worse COVID-19–related outcomes compared with non-Hispanic White patients, after adjusting for demographic and clinical risk factors?
Findings
In this cohort study of 3506 patients, Black patients with cancer experienced significantly more severe COVID-19 outcomes compared with White patients with cancer, after adjustment for demographic and clinical risk factors.
Meaning
These findings suggest that, within the framework of structural racism in the US, having cancer and COVID-19 is associated with worse outcomes among Black patients compared with White patients.
Importance
Non-Hispanic Black individuals experience a higher burden of COVID-19 than the general population; hence, there is an urgent need to characterize the unique clinical course and outcomes of COVID-19 in Black patients with cancer.
Objective
To investigate racial disparities in severity of COVID-19 presentation, clinical complications, and outcomes between Black patients and non-Hispanic White patients with cancer and COVID-19.
Design, Setting, and Participants
This retrospective cohort study used data from the COVID-19 and Cancer Consortium registry from March 17, 2020, to November 18, 2020, to examine the clinical characteristics and outcomes of COVID-19 in Black patients with cancer. Data analysis was performed from December 2020 to February 2021.
Exposures
Black and White race recorded in patient’s electronic health record.
Main Outcomes and Measures
An a priori 5-level ordinal scale including hospitalization intensive care unit admission, mechanical ventilation, and all-cause death.
Results
Among 3506 included patients (1768 women [50%]; median [IQR] age, 67 [58-77] years), 1068 (30%) were Black and 2438 (70%) were White. Black patients had higher rates of preexisting comorbidities compared with White patients, including obesity (480 Black patients [45%] vs 925 White patients [38%]), diabetes (411 Black patients [38%] vs 574 White patients [24%]), and kidney disease (248 Black patients [23%] vs 392 White patients [16%]). Despite the similar distribution of cancer type, cancer status, and anticancer therapy at the time of COVID-19 diagnosis, Black patients presented with worse illness and had significantly worse COVID-19 severity (unweighted odds ratio, 1.34 [95% CI, 1.15-1.58]; weighted odds ratio, 1.21 [95% CI, 1.11-1.33]).
Conclusions and Relevance
These findings suggest that Black patients with cancer experience worse COVID-19 outcomes compared with White patients. Understanding and addressing racial inequities within the causal framework of structural racism is essential to reduce the disproportionate burden of diseases, such as COVID-19 and cancer, in Black patients.
The COVID-19 pandemic has led to an estimated 33 million cases and more than 604 000 COVID-19–related deaths in the US alone (as of July 16, 2021).1 Racial and ethnic minority groups, particularly non-Hispanic Black individuals, bear a disproportionate burden of COVID-19, with higher rates of infection, hospitalization, and death compared with non-Hispanic White individuals.2-6 Although Black individuals represent 13% of the US population, they account for 20% of COVID-19 cases and 23% of COVID-19–related deaths.6 Observations of disparate racial and ethnic burden of COVID-19 have been broadly documented across geographical regions.7-11
Comorbidities, including cancer, predispose patients to an increased risk of severe COVID-19 illness and death.12-14 At present, detailed data on racial disparities with respect to baseline prognostic factors, illness course, and outcomes among patients with cancer are limited.12 Before the COVID-19 pandemic, it was well described that Black patients with cancer have the highest death rates compared with all other racial and ethnic groups.15 Factors associated with racial disparities among patients with cancer are complex and likely constitute an interplay of socioeconomic status, preexisting comorbid conditions, access to care, and other social determinants of health (SDOH). Racial and ethnic minority groups have long experienced cancer health disparities, with a disproportionately higher burden of exposure to factors known to be associated with increased cancer risk (eg, smoking, obesity, and unhealthy diet), decreased screening and cancer prevention (and, thus, delayed cancer detection), and fewer opportunities to receive advances in cancer treatment or standard of care.6 Environmental, genetic, biological, behavioral, clinical, social, psychological, and cultural factors may contribute as well.16-18 Hence, we hypothesized that US Black patients with cancer and COVID-19 have worse baseline clinical characteristics, severity of COVID-19 presentation, complications, and outcomes compared with White patients after adjusting for demographic and clinical risk factors.
The COVID-19 and Cancer Consortium (CCC19) registry (eAppendix 1 and eTable 1 in Supplement 1) captures detailed clinical characteristics, course of illness, and outcomes of COVID-19 among patients with cancer.13,19,20 Our target population included any patient with cancer and confirmed diagnosis of COVID-19 cared for at one of our participating institutions (eAppendix 2 in Supplement 1). For this registry-based, retrospective cohort study, we included all reports of laboratory-confirmed SARS-CoV-2 infection submitted to the CCC19 registry between March 17, 2020, and November 18, 2020, for US residents with current or past diagnosis of cancer and Black or White race. Race and ethnicity were derived from the patient’s electronic health record (EHR), which was either self-reported or assigned by health care practitioner or triage personnel. Excluded cancers were precursor hematological malignant neoplasms (eg, monoclonal gammopathy of undetermined significance), in situ carcinoma (except bladder), and nonmelanomatous, noninvasive skin cancer19 (eFigure 1 in Supplement 1). This study was approved by the Vanderbilt University institutional review board and participating sites. Informed consent was waived because the data were anonymous, and the study posed minimal risk to participants, in accordance with 45 CFR §46. Reporting of results follows the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline.21
Patient-reported race and ethnicity were captured following the Centers for Disease Control and Prevention Race and Ethnicity codes.22 The primary outcome was a 5-level ordinal scale of COVID-19 severity based on a patient’s most severe disease status: (1) none of the complications listed here, (2) hospital admission, (3) intensive care unit admission, (4), mechanical ventilation use, and (5) death from any cause.23 Index date for analysis was defined as diagnosis of COVID-19, and outcomes were assessed over the patients’ total follow-up period. We performed an additional analysis with 30-day all-cause mortality as a secondary outcome.
The Institute of Medicine defines disparity as a difference in treatment provided to members of different racial (or ethnic) groups that is not due to access-related factors or needs or justified by the underlying health conditions or preferences of patients.24 Implementing the Institute of Medicine’s definition of disparity,24 only those factors not considered to be associated with disparity (ie, allowable covariates) were included in the analysis to account for the direction of the associations.25
Allowable covariates included demographic variables (age and sex); health behaviors (smoking status); functional status (Eastern Cooperative Oncology Group performance status, obesity, diabetes, kidney disease, pulmonary, and cardiovascular comorbidities); underlying malignant neoplasms (type of malignant neoplasm [solid or hematological], cancer status at the time of COVID-19 diagnosis [remission or no evidence of disease, active responding to therapy, stable, or progressing]); disease management (timing and modality of anticancer therapy before COVID-19 diagnosis, such as cytotoxic chemotherapy, immunotherapy, targeted therapy, endocrine therapy, locoregional therapy, radiotherapy and/or surgery with or without nodal dissection, and other); and pandemic dynamics (US Census region of patient’s residence and month of COVID-19 diagnosis to accommodate spatiotemporal trends and evolution in the clinical care and management of patients with COVID-19). The CCC19 data dictionary has been published elsewhere.26 Unavailable or unmeasured variables included ancestry, genetics, structural racism or racialization, societal factors (eg, language, culture, and community dynamics), physical environment (eg, air pollution, overcrowding, and green space), and access to care (eg, health insurance or enrollment in clinical trials).
A statistical analysis plan including model specification was predetermined before the analysis and was revised upon submission by the lead authors and the CCC19 Epidemiology, Biostatistics, and Informatics Cores (eAppendix 3 and eAppendix 4 in Supplement 1). We used standard descriptive statistics to summarize baseline covariates, rates of clinical complications (eg, cardiovascular and pulmonary complications or acute kidney injury), interventions after COVID-19 diagnosis (ie, supplemental oxygen, transfusion, remdesivir, hydroxychloroquine, and corticosteroids), and individual components of the ordinal severity outcome. We calculated unweighted and weighted absolute standardized mean differences for baseline covariates to evaluate the balance between Black and White patients; an absolute standardized mean difference less than 0.1 indicated balance.
Racial disparities in COVID-19 severity were estimated from minimally and fully adjusted multivariable ordinal logistic regression models and 30-day all-cause mortality from logistic and modified Poisson regression models.27,28 Treatment variables were binary indicators to account for patients receiving multiple therapies (eTable 2 in Supplement 1). The assumed functional form for continuous variables (age) was based on exploratory analyses (eFigure 2 in Supplement 1). Race-stratified estimates for obesity, comorbidities, and cancer status were obtained from adjusted models with interaction terms between race and these factors, given their known association with cancer and COVID-19 health disparities.6
In addition, we estimated inverse probability of treatment weighted differences in COVID-19 severity between Black and White patients from an ordinal logistic regression model and 30-day mortality from both a logistic regression model (to estimate odds ratios [ORs]) and a modified Poisson regression model (to estimate relative risks).28 All models included race as the sole covariate, were weighted by the reciprocal of the probability of receiving the treatment (ie, race) that was actually received, and used a robust (ie, sandwich) variance estimator to account for the uncertainty due to estimation of the weights (and for the modified Poisson model, to account for misspecification of the variance structure).
We used the e-value to quantify sensitivity to unmeasured confounding.29,30 Additional details on evaluating proportional odds assumptions (eFigure 3 in Supplement 1), multiple imputation to impute missing and unknown data (10 iterations; missingness rates were <5%), and additional statistical methods are provided in the eAppendix 4 in Supplement 1.31 Analyses were performed using R statistical software version 4.0.3 (R Project for Statistical Computing), including the Hmisc, rms, MASS, and robust extension packages. Data analysis was performed from December 2020 to February 2021.
From 3506 patients (1768 women [50%]; median [IQR] age, 67 [58-77] years) included in the analysis (eFigure 1 in Supplement 1), 1068 (30%) were Black and 2438 (70%) were White (Table 1). The median (IQR) duration of follow-up was 42 (29-90) days for the overall cohort, 63 (27-90) days for Black patients, and 42 (30-90) days for White patients. The median (IQR) age at COVID-19 diagnosis was 65 (57-74) for Black patients and 68 (58-78) years for White patients. At the time of COVID-19 diagnosis, Black patients had higher rates of obesity (480 Black patients [45%] vs 925 White patients [38%]), diabetes (411 Black patients [38%] vs 574 White patients [24%]), and kidney disease (248 Black patients [23%] vs 392 White patients [16%]) compared with White patients. White patients had higher rates of cardiovascular disease compared with Black patients (907 White patients [37%] vs 338 Black patients [32%]).
Most malignant neoplasms were solid tumors, with breast cancer (707 patients [20%]) being the most common solid tumor overall across both racial groups. No differences between types of cancer were observed between the 2 racial groups (eTable 3 in Supplement 1). Cancer status was similar between the 2 racial groups, with 555 Black patients (52%) and 1346 White patients (55%) in remission. Proportions of patients with active and responding (123 Black patients [12%] and 229 White patients [9%]), active and stable (160 Black patients [15%] and 391 White patients [16%]), active and progressing (140 Black patients [13%] and 292 White patients [12%]), and unknown cancer status (88 Black patients [8%] and 178 White patients [7%]) were similar between the 2 racial groups (Table 1). The proportions of patients with localized (597 Black patients [56%] and 1357 White patients [56%]), disseminated (266 Black patients [25%] and 552 White patients [23%]), or missing or unknown cancer stage (205 Black patients [19%] and 529 White patients [22%]) were also similar between Black and White patients. Almost one-half of patients had not received anticancer therapy within 3 months of COVD-19 diagnosis in both racial groups (523 Black patients [49%] and 1240 White patients [51%]). Additional baseline characteristics are shown in Table 1 and in eTable 2, eTable 3, and eTable 4 in Supplement 1.
COVID-19–Related Clinical Outcomes, Complications, and Interventions
Black patients were more likely than White patients to have moderate (437 Black patients [41%] vs 826 White patients [34%]) or severe (164 Black patients [15%] vs 262 White patients [11%]) disease at COVID-19 diagnosis. Pulmonary complications were the most common (1289 patients [37%]), with higher rates observed among Black patients (442 patients [42%]) than White patients (847 patients [35%]) (Table 2). Similarly, Black patients had higher rates of acute kidney injury (275 Black patients [27%] vs 349 White patients [15%]) and cardiovascular complications (267 Black patients [26%] vs 526 White patients [22%]) compared with White patients (Table 2 and eTable 5 in Supplement 1). Black patients were less likely than White patients to be treated with remdesivir (61 Black patients [6%] vs 242 White patients [10%]) but were more likely to be treated with hydroxychloroquine (245 Black patients [24%] vs 348 White patients [15%]), which is consistent with our prior report on a smaller subset of patients.23
Higher rates of hospitalization, intensive care unit admission, and mechanical ventilation were observed among Black patients compared with White patients (Table 2). In addition, a higher rate of all-cause mortality was observed among Black patients (206 patients [19%]) compared with White patients (412 patients [17%]). Of the 618 patients who died during follow-up, 507 (82%) died within 30 days of COVID-19 diagnosis, with a 30-day mortality rate of 17% (181 patients) among Black patients and 13% (326 patients) among White patients.
Multivariable Regression Analysis for Disease Severity and Mortality
Multivariable models revealed significantly higher COVID-19 severity (OR, 1.34; 95% CI, 1.15-1.58) and 30-day mortality (OR, 1.59; 95% CI, 1.25-2.02) among Black patients compared with White patients, after adjustment for baseline covariates (Table 3). The propensity scores for race were balanced and overlapping (eFigure 4 in Supplement 1). After balancing racial groups with respect to baseline covariates (eFigure 5 in Supplement 1), the OR for COVID-19 severity was 1.21 (95% CI, 1.11-1.33), and the relative risk of mortality was 1.14 (95% CI, 0.95-1.37) for Black patients compared with White patients (Table 3).
Significant interactions were observed for obesity and race and for cancer status and race (Figure). In particular, obesity was associated with higher COVID-19 severity (OR, 1.38; 95% CI, 1.07-1.78) and 30-day mortality (OR, 1.54; 95% CI, 1.05-2.24) among Black patients, but obesity was not associated with these outcomes among White patients with cancer (COVID-19 severity, OR, 0.99; 95% CI, 0.82-1.18; 30-day mortality, OR, 0.92; 95% CI, 0.68-1.25). Actively progressing cancer was also significantly associated with increased COVID-19 severity among Black patients (OR, 4.55; 95% CI, 3.02-6.87) compared with White patients (OR, 2.76; 95% CI, 2.04-3.73). No other significant interactions were observed.
The e-value for the unweighted mortality OR was 1.83, and the e-value for the 95% CI was 1.48. Thus, an unobserved factor would need to be associated with both race and mortality with a risk ratio of at least 1.83 to fully attenuate the observed association; the risk ratio would need to be at least 1.48 for the null-hypothesized value (1.0) to be included in the 95% CI. Such an association is larger than most documented associations in the CCC19 cohort.23 The 95% CI from the weighted model for mortality included the null value.
The COVID-19 pandemic has highlighted and exacerbated longstanding health and social inequities in the US. These are likely the same inequities that fuel the disparities seen across the cancer control continuum and that lead to higher mortality rates among Black patients.32 Given the paucity of data on one of the most vulnerable racial and ethnic groups,15,33 in this cohort study, we examined a range of clinically meaningful characteristics and outcomes in Black patients with cancer and COVID-19 in the US. We used a novel ordinal outcome of COVID-19 severity to capture the full spectrum of COVID-19 complications that may vary across different racial and ethnic groups and also explored the interactions between comorbidities and cancer to understand their synergistic effect on COVID-19 outcomes in different racial groups.34
Compared with White patients, Black patients had worse COVID-19 presentations and experienced significantly higher COVID-19 severity; this difference was consistent across different analysis methods. These findings are complementary to a recent EHR report that showed African American patients with cancer and COVID-19 had higher rates of hospitalization and death.12 Our study validates and adds to their findings by examining a large cohort of Black patients with more granular data on the cancer status, severity of COVID-19 at presentation, course of illness, including systemic complications, and outcomes over longitudinal follow-up. Structural racism refers to the ways in which societies reinforce systems of health care, law enforcement, education, employment, benefits, media, and housing that perpetuate discriminatory distribution of resources and attitudes.35,36 The COVID-19 pandemic highlighted the health burden on racial and ethnic minority groups and the complexity of structural racism, which has led to disproportionately worse clinical outcomes among Black patients.37,38 Cancer health disparities have been well described elsewhere6,18; for example, Black women have a disproportionately higher breast cancer–specific mortality compared with White women, and Black men have a higher incidence and mortality from prostate cancer compared with White men. Factors such as access to care and SDOH that contribute to racial disparities in patients with cancer are complex and potentially extend to disparities in COVID-19 outcomes as well.
How should these findings be interpreted? The inequity in access to quality health care that can lead to worse baseline clinical factors and ultimately severe complications among racial and ethnic minority groups is well known.6 Our findings are similar to the patterns of racial disparities observed among patients with cancer, which points to an overlap in the root causes of racial inequities between cancer and COVID-19. In addition, racial and ethnic minority groups are more likely to live in conditions that pose a challenge to social distancing and also are more likely to be essential workers; therefore, sheltering in place may not be a possibility for many of them, thus putting these populations at an increased risk for exposure to SARS-CoV-2.6,39 These and additional sociodemographic pressures such as underinsurance may lead to delays in seeking medical care, which would likely be associated with more severe COVID-19 upon presentation.
Unfortunately, if these same racial inequities in access to medical care hold for cancer screening, in the near future, we are likely to see worsening disparities in rates of advanced stage cancers at diagnosis.6 The COVID-19 pandemic has been especially challenging for the treatment of patients with cancer.40 In our study, the racial disparities in COVID-19 severity were sustained for patients receiving active cancer therapy (Table 3). In addition, there are a host of drug interactions between chemotherapeutic agents and COVID-19 therapies, leading to alterations in standard treatments. For patients receiving radiation, the pandemic has caused delays between radiotherapy sessions, possibly leading to a reduction in therapeutic efficacy.41 Finally, current and other studies23,42,43 have demonstrated that Black patients with COVID-19 are less likely to receive novel anti–COVID-19 therapies (eg, remdesivir) compared with their White counterparts. Our findings that Black patients with cancer and COVID-19 were less likely to receive remdesivir, despite presenting with worse disease, may reflect a persistent gap in health care access and equity for Black patients. Unequal access and mistrust of the medical profession among vulnerable populations has resulted in lower rates of vaccine trial enrollment44 and COVID-19 vaccinations received in the Black community,45 all of which will further exacerbate racial disparities unless urgent remedial actions are undertaken.
Strengths and Limitations
The current study has several strengths, including being, to our knowledge, the largest cohort to date of Black patients with cancer and COVID-19. Furthermore, we present data representative of Black patients across diverse age groups, cancer types, cancer status, geographical census regions, and academic and community centers, with longer-term follow-up beyond 30 days. Despite these strengths, there remain limitations associated with incomplete documentation of race and ethnicity, a commonly encountered problem in EHRs, and inherent lack of granularity in the Centers for Disease Control and Prevention classification schema chosen for the registry. We also did not examine the association of COVID-19 with cancer among Hispanic Black patients. Gender was collected in the survey, including a third nonbinary option. For the purposes of this analysis, we mapped gender to sex: woman to female, man to male, and nonbinary to unknown or missing. We acknowledge that this may lead to a mismatch between biological sex and gender identity, which is an inherent limitation of both the survey and underlying EHR data that is available to the respondents. Although a number of CCC19 participating sites are also National Cancer Institute Community Oncology Research Program sites, there is potentially incomplete capture of subpopulations of patients (eg, rural populations) who may not seek care at the mostly urban health care centers that compose the CCC19. In addition, CCC19 does not collect detailed data on SDOH, primarily because they are often not recorded within EHRs.46 Because insurance (a surrogate of health care access) is a contributor of disparity, it was considered as a nonallowable covariate and, thus, was not included in the analysis. A sensitivity analysis including insurance showed a marginal decrease in the OR for COVID-19 severity outcome and a negligible change in OR or relative risk for mortality (eTable 6 in Supplement 1). Thus, much if not all the disparity in COVID-19 severity between Black and White patients with cancer could be explained by measurable and sometimes modifiable factors.
Our study found that Black patients with cancer and COVID-19 have similar cancer status but worse preexisting comorbidities, severity of COVID-19 at presentation, and outcomes compared with White patients with cancer and COVID-19. Understanding and addressing the cumulative and synergistic association of racial inequities (eg, preexisting comorbidities, SDOH, and inadequate access to quality health care and cutting-edge research) on clinical outcomes is pivotal. This is a call for action to eradicate root causes of racial inequities, within the causal framework of structural racism, to reduce the disproportionate burden of diseases, such as COVID-19 and cancer, among Black patients and, possibly, other minority racial and ethnic groups.
