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.

Recruiting African American Prostate Cancer Survivors for a Population-based Biobank Study

BACKGROUND

Prostate cancer affects African American men disproportionately compared with men of other racial/ethnic groups. To identify biological bases for this health disparity, we sought to create a state-wide biobank of African American prostate cancer survivors in Florida.

METHODS

African American men diagnosed with prostate cancer between 2013 and 2017 and living in Florida at diagnosis were identified through the State of Florida's cancer registry. Individuals were approached via mail and telephone, assessed for eligibility, and asked for informed consent. χ2 and t tests were conducted to identify differences between eligible and reachable individuals (i.e., had valid contact information) versus consented participants.

RESULTS

Of the 5,960 eligible and reachable individuals, 3,904 were eligible and contacted at least once, and 578 consented [overall consent rate = 10% (578/5,960); adjusted consent rate = 15% (578/3,904)]. Statistically significant (Ps < 0.05) but small differences in demographic and clinical variables were observed. Consented participants were less likely to be older than 64 (35% vs. 41%) and less likely to have received radiotherapy (36% vs. 41%) and hormone therapy (16% vs. 21%), but more likely to have regional prostate cancer (13% vs. 11%) and have undergone surgery (44% vs. 39%). Consented participants did not differ from reachable individuals on other demographic and clinical factors (Ps > 0.05).

CONCLUSIONS

Recruiting African American prostate cancer survivors to biobanking research through a cancer registry is feasible. However, the consent rate was low, and existing challenges limit consent and participation.

IMPACT

Strategies for overcoming barriers to informed consent and increasing participation in biospecimen research are needed to address cancer disparities.

King's Health Partners' Prostate Cancer Biobank (KHP PCaBB)

The KHP PCaBB was established in 2013 and recruits donors from the Urology or Oncology Departments at Guy's Hospital in London (UK). Prostate cancer patients may be approached to give their consent for biobanking at any point in their treatment pathway, which allows residual material from their earlier diagnosis to be transferred and used by the Biobank. Currently, patients are specifically asked to donate samples of blood and surplus prostate tissue as well as permitting access to their clinical and pathological data that continues to be added throughout the course of their disease. Between 2013 and 2015, 549 prostate cancer patients gave their consent to the biobank and, the tissue repository collected 489 blood samples, 120 frozen prostate tissue samples and 1064 formalin fixed paraffin embedded diagnostic blocks.Prostate cancer has become a chronic disease in a large proportion of men, with many men receiving multiple subsequent treatments, and their treatment trajectory often spanning over decades. Therefore, this resource aims to provide an ideal research platform to explore potential variations in treatment response as well as disease markers in the different risk categories for prostate cancer.A recent audit of the KHP PCaBB revealed that between 2013 and 2015, 1796 patients were diagnosed with prostate cancer at King's Health Partners (KHP), out of which 549 (30.6%) gave their consent to KHP PCaBB. Comparisons between demographic and clinical characteristics of patients who had consented compared to the total patient population revealed that the KHP PCaBB is demographically representative of the total prostate cancer patient population seen in Guy's and St Thomas' NHS Foundation Trust (GSTT). We observed no differences in distribution of ethnicity (p = 0.507) and socioeconomic status (p = 0.097). Some differences were observed in clinical characteristics, specifically with treatment type - which differed significantly between the patients who had given consent and total patient population.The KHP PCaBB has thereby amassed a rich data and tissue repository that is largely reflective of both the demographic and clinical diversity within the total prostate cancer patient population seen at KHP, making it an ideal platform for prostate cancer research.

The Cancer Survivorship Journey: Models of Care, Disparities, Barriers, and Future Directions

Although the number of long-term cancer survivors has increased substantially over past years, the journey of survivorship does not always include high-quality, patient-centered care. A variety of survivorship care models have evolved based on who provides this care, the survivor population, the site of care, and/or the capacity for delivering specific services. Other areas of survivorship care being explored include how long follow-up care is needed, application of a risk-based approach to survivorship care, and the role of the survivor in his or her own recovery. However, there is little evidence indicating whether any models improve clinical or patient-reported outcomes. A newer focus in survivorship care has included assessment of potential disparities; the sociodemographic characteristics of population subgroups associated with barriers to receiving high-quality cancer treatment may also affect the survivorship period. Developing policies and programs to address disparities in survivorship care is not simple, and examining how financial hardship affects cancer outcomes, reducing economic barriers to care, and increasing incorporation of patient-centered strategies may be important components. Here too, there is little evidence regarding the best strategies to address these disparities. Barriers to providing high-quality, patient-centered survivorship care include lack of evidence, lack of a trained survivorship workforce, lack of reimbursement structures/insurance coverage, and lack of a health care system that reduces fragmented care. Future research needs to focus on developing a survivorship care evidence base, exploring strategies to facilitate provision of survivorship care, and disseminating best survivorship care practices to diverse and international audiences.

Racial variation in the clinical and economic burden of skeletal-related events among elderly men with stage IV metastatic prostate cancer

Prostate cancer (PCa) outcomes vary widely among African American (AA) and non-Hispanic White (NHW) men. The authors investigated racial variation in the incidence of skeletal-related events (SREs) and SRE-related healthcare costs among AA and NHW men, a topic that has received limited attention in the literature. AA and NHW men diagnosed with metastatic PCa were identified from the linked Surveillance, Epidemiology and End Results-Medicare dataset. The sample included 6455 men with metastatic PCa, including 5420 NHW men and 1035 AA men. Approximately 16% experienced SREs during follow-up. AA men were less likely to experience SREs compared with NHW men, controlling for individual characteristics (adjusted odds ratio: 0.79; 95% CI: 0.66- 0.94). The SRE-specific costs were US$35,725 (US$22,190-US$49,260) among AA men and US$25,896 (US$21,669-US$30,123) among NHW men. Although AA men were less likely to experience SREs, there were substantial costs attributable to the treatment of SREs among AA men.
