The experience of treatment barriers and their influence on quality of life in American Indian/Alaska Native breast cancer survivors

Race, ethnicity, and experienced racism are associated with adverse physical and mental health outcomes among cancer survivors

INTRODUCTION

Survivors of cancer are at risk for adverse mental and physical health outcomes. It is not well understood, however, how these outcomes are differentially experienced according to an individual's exposure to racism. This study sought to evaluate associations of race/ethnicity, and experiences of racism, with adverse health outcomes in survivors of cancer.

METHODS

Using the Behavioral Risk Factor Surveillance System database, data from 48,200 survivors between 2014 and 2020 were evaluated. Survey items included negative physical and emotional symptoms as a result of race-based treatment. Outcomes of interest included days of poor mental and physical health, activity limitations, depression, and inadequate sleep. Associations using prevalence ratios were evaluated.

RESULTS

All historically marginalized racial/ethnic groups were more likely to experience at least one adverse health outcome compared with non-Hispanic White survivors. Those who physically experienced racism were 2.1 (95% CI, 1.64-2.69) times as likely to report poor physical health, 3.51 (95% CI, 2.61-4.71) times as likely to report poor mental health, 2.14 (95% CI, 1.77-2.58) times as likely to report inadequate sleep, 2.33 (95% CI: 1.91-2.83) times as likely to report depression, and 1.42 (95% CI, 1.04-1.93) times as likely to report activity limitations compared with those who have not experienced racism. Similar associations were observed for emotionally experienced racism.

DISCUSSION

Racial inequities in health outcomes for survivors of cancer from marginalized racial/ethnic groups are well-established. Experienced racism contributes to adverse health outcomes and widens these disparities. Improving outcomes for survivors of cancer may require screening for experienced racism.

PLAIN LANGUAGE SUMMARY

Survivors of cancer from marginalized racial/ethnic populations are more likely to have poor mental and physical health than their non-Hispanic White counterparts. Whether survivors from certain racial/ethnic populations of smaller size also have poorer health is less well understood. Generally, individuals who report experienced racism also report poor health, this association has not been studied in survivors of cancer. This study, from a national survey of survivors of cancer, describes disparities in health outcomes experienced by a variety of racial and ethnic populations. Our findings suggest racism is associated with poor mental and physical health in survivors of cancer.

Health Disparities in Cancer Among American Indians and Alaska Natives

American Indians and Alaska Natives (AI/AN) are underserved populations who suffer from several health disparities, 1 of which is cancer. Malignancies, especially cancers of the breast, liver, and lung, are common causes of death in this population. Health care disparities in this population include more limited access to diagnostic radiology because of geographic and/or health system limitations. Early detection of these cancers may be enabled by improving patient and physician access to medical imaging. Awareness by the radiology community of the cancer disparities among this population is needed to support research targeted to this specific ethnic group and to support outreach efforts to provide more imaging opportunities. Providing greater access to imaging facilities will also improve patient compliance with screening recommendations, ultimately improving mortality in these populations.

Disparities in Breast-Conserving Therapy for Non-Hispanic American Indian/Alaska Native Women Compared with Non-Hispanic White Women

BACKGROUND

Little is known about the surgical patterns of American Indian/Alaska Native (AI/AN) breast cancer patients. The purpose of this study is to determine whether there are disparities in breast cancer surgery and radiation therapy between non-Hispanic AI/AN (NH-AI/AN) women and non-Hispanic White (NHW) women.

METHODS

Data from the National Program of Cancer Registries of the Centers for Disease Control and Surveillance, Epidemiology, and End Results were used for this cross-sectional study. Female patients with invasive breast cancer diagnosed 2010-2015 were stratified by race/ethnicity, surgical procedure, radiation, and region. Percentage distributions of mastectomy and lumpectomy were compared overall and by region and stage.

RESULTS

From 2010 to 2015 there were 3292 NH-AI/AN women and 165,225 NHW women diagnosed with breast cancer. For early stage (AJCC stage 1 and 2), NH-AI/AN women had overall significantly higher percentage of mastectomy (41% vs 34.4%, p < 0.001) and significantly lower percentage of lumpectomy (59% vs 65.6%) compared with NHW women, without significant differences in post-lumpectomy radiation (71% vs 70%). There were regional variations, notably in the Northern Plains, where the percentage of mastectomy for early-stage disease was 48.9% for NH-AI/AN women versus 35.9% for NHW women, and in Alaska with 47% for NH-AI/AN women versus 33.3% for NHW women (p < 0.001). There were no overall significant differences in type of surgery or radiation for late-stage disease between groups.

CONCLUSION

This is the first study to show disparities in surgical management of NH-AI/AN women with breast cancer. For early-stage disease, NH-AI/AN women undergo a higher percentage of mastectomy. Future clinical directions could focus on the factors that drive awareness, decision-making, and access to breast conservation.

Gender and sex disparity in cancer trials

The study population within phase III clinical trials leading to approval of new cancer agents should ideally more closely mirror the population who will ultimately receive these agents. Although the number of females participating in clinical trials has increased over the past several decades, females are still under-represented in preclinical studies, in early phase clinical trials and even in some later phase cancer clinical trials. In the USA, this is particularly true for women from minority populations and elderly women. In this review, we review gender and sex disparities in cancer trials, the reasons for these disparities, the barriers to clinical trial enrolment and ways to improve diversity in cancer clinical trials.

Psychosocial Aspects of Delivering Cancer Care to Indigenous People: An Overview

Globally, a growing body of evidence has reported significant disparities in cancer outcomes between indigenous and nonindigenous people. Although some effort is being made to address these disparities, relatively little attention has been directed toward identifying and focusing on the psychosocial aspects of cancer care for indigenous patients, which are critical components in improving cancer care and outcomes. The purpose of this article is to describe the results of a scoping review of the psychosocial aspects of cancer care for indigenous people. We highlight considerations in undertaking research in this field with indigenous people and the implications for clinical practice.

Health care access and utilization among adult cancer survivors: Results from the National Institutes of Health "All of Us" Research Program

Background

Many cancer survivors face financial difficulties that prevent them from receiving appropriate health care. Racial/ethnic disparities in receipt of health care have been reported among cancer survivors, but recent data for important racial/ethnic subgroups of the US population are lacking.

Methods

To learn more about barriers to healthcare access faced by cancer survivors, we analyzed data from the NIH “All of Us” Research Program. Data were analyzed about demographic factors and other personal characteristics, personal medical history of cancer, healthcare utilization, and access to care.

Results

As of November 2020, a total of 5426 participants had a history of cancer (excluding skin cancer). About 88.2% were non‐Hispanic White; 3.9% were Black, African American, or African; 1.3% were Asian; 4.1% were Hispanic, Latino, or Spanish; and 1.2% reported more than one race. Just over one‐half had an annual income of $75,000 or greater. The majority of the participants (71.7%) were college graduates or had an advanced degree. About 47.0%% had private health insurance, 41.0% had Medicare, 6.0% had Medicaid, and the remainder had military, Veterans Affairs, other insurance, or no health insurance. Frequently cited reasons for delayed care in the past 12 months were “had to pay out of pocket for some or all of the procedures,” “deductible was too high/or could not afford the deductible,” “couldn't afford the copay,” “couldn't get time off work,” and “were nervous about seeing a health care provider.”

Discussion

A minority of cancer survivors who participated in the NIH “All of Us” Program had difficulty paying for health care in the past 12 months. Of particular concern are minorities such as African American and Hispanic cancer survivors along with those who are low income.

Genomic expression assay testing among American Indian and Alaska Native women with breast cancer

BACKGROUND

Breast cancer is one of the most common causes of cancer mortality for all women, including American Indian and Alaska Native (AI/AN) women. The use of the 21-gene recurrence score (RS) appears to be predictive of the benefit of chemotherapy for women with estrogen receptor (ER)-positive breast cancer. The objective of the current study was to compare RS testing between AI/AN and non-Hispanic White (NHW) women with breast cancer.

METHODS

The Surveillance, Epidemiology, and End Results program was used to identify women with ER-positive breast cancer from 2004 through 2015. Multivariable logistic regression was used to evaluate factors associated with RS use, with high-risk RS, and with chemotherapy use among those with a high-risk RS.

RESULTS

A total of 363,387 NHW patients and 1951 AI/AN patients with ER-positive breast cancer were identified. AI/AN women were found to be less likely to undergo RS testing and, when tested, were more likely to have a high-risk RS. In the multivariable logistic regression analysis, AI/AN women were found to be significantly more likely to have a high-risk RS (odds ratio,1.28; 95% confidence interval, 1.01-1.66). Among untested women, chemotherapy use was higher for AI/AN women; however, the use of chemotherapy was not found to be significantly different between the groups with a high-risk RS. Using Cox proportional hazards models, AI/AN race was found to be significantly associated with worse overall survival.

CONCLUSIONS

AI/AN women were less likely to undergo RS testing compared with NHW women and were more likely to have a high-risk RS. Reversing the disparity in genomic expression assay testing is critical to ensure guideline-based breast cancer treatment and improve survival rates for AI/AN women with breast cancer.

American Indians and Alaska Natives: Resolving Disparate Cancer Outcomes

American Indians and Alaska Natives (AIANs) have been documented as a population with high rates of cancer mortality in comparison to other racial and ethnic groups in the United States. During a time when other populations in the United States are experiencing improvements in cancer outcomes, cancer disparities in AIANs persist. The disparities in cancer outcomes in this diverse population can be attributed to a complex constellation of factors, which include access-to-care, economic, medical, and individual barriers, and mistrust and disenfranchisement.

Surgical Compliance and Outcomes in Gastric Cancer: a population-based cohort study

Background: Surgical resection is one of curative treatment for gastric cancer (GC), however, a set of patients show poor surgical compliance in the USA. We aimed to identify the risk factors associated with surgical compliance and investigate the difference in survival.

Methods: GC patients diagnosed between 1973 and 2014 were identified from the Surveillance Epidemiology and End Results (SEER) databases. Based on different surgical compliance and treatment regimen, patients were classified into three subgroups: surgical compliance group, surgical noncompliance group, and non-surgical group. Multivariable Logistic regression analysis was adopted to identify the factors related to surgical compliance; Multivariable Cox regression was used to investigate the prognostic factors. Overall survival (OS) and cancer-specific survival (CSS) were analyzed using the Kaplan-Meier estimator method.

Results: Of 79374 GC patients who were recommended for surgical therapy, 15201(19.2%) cases did not perform surgery. Poor compliance of surgery was related to old age, American Indian/Alaska Native race, poor grading/late staging, single/widowed status, lower socioeconomic status and earlier time of diagnosis. As expected, GC patients of surgical compliance group showed significantly more favorable survival than the other two groups (P<0.0001); notably, the outcome of surgical noncompliance group came close to that of non-surgical group.

Conclusion: GC patients of poor surgical compliance demonstrated adverse survival, which was comparable to that of non-surgical patients. The poor surgical compliance was associated with older age, American Indian/Alaska Native race, poor tissue differentiation/advanced stage of tumor, single/widowed status, lower socioeconomic status and earlier time of diagnosis.
