Layers of information: interacting constraints on breast cancer risk-management by high-risk African American women

Barriers and facilitators to breast cancer screening among high-risk women: a qualitative study

PURPOSE

Women with greater than 20-25% lifetime breast cancer risk are recommended to have breast cancer screening with annual mammogram and supplemental breast MRI. However, few women follow these screening recommendations. The objective of this study was to identify barriers and facilitators of screening among women at high risk for breast cancer, guided by the Health Services Utilization Model (HSUM).

METHODS

Unaffected high-risk women (N=63) completed semi-structured qualitative interviews exploring their experiences with breast cancer screening. Interviews were audio recorded, transcribed verbatim, and analyzed using a combined deductive and inductive approach.

RESULTS

Most participants (84%) had received a screening mammogram; fewer (33%) had received a screening breast MRI. Only 14% had received neither screening. In line with the HSUM, qualitative analysis identified predisposing factors, enabling factors, and need factors associated with receipt of breast cancer screening. Enabling factors - including financial burden, logistic barriers, social support, and care coordination - were most frequently discussed. Predisposing factors included knowledge, health beliefs, and self-advocacy. Need factors included healthcare provider recommendation, family history of breast cancer, and personal medical history. Although HSUM themes were consistent for both mammography and breast MRI, participants did highlight several important differences in barriers and facilitators between the two screening modalities.

CONCLUSION

Barriers and enabling factors associated with supplemental screening for high-risk women represent possible intervention targets. Future research is needed to develop and test multilevel interventions targeting these factors, with the ultimate goal of increasing access to supplemental screening for high-risk women.

Comparing Breast Cancer and Cardiovascular Disease Risk and Use of Chemoprevention and Statins among Women with High-risk Breast Lesions

Breast cancer chemoprevention with selective estrogen receptor modulators (SERM) or aromatase inhibitors (AI) remains underutilized among high-risk women. A potential barrier to chemoprevention is competing comorbidities such as atherosclerotic cardiovascular disease (ASCVD), due to concern for additional medication side effects. We conducted a retrospective cohort study among women with atypical hyperplasia (AH) or lobular carcinoma in situ (LCIS), an important target population for chemoprevention. We compared risks for breast cancer and ASCVD, as well as use of SERMs/AIs versus statins among high-risk women (defined as a 5-year invasive breast cancer risk ≥1.67% and 10-year ASCVD risk ≥7.5%, respectively). We used clinical data extracted from the electronic health record to calculate breast cancer risk according to the Breast Cancer Surveillance Consortium model and ASCVD risk according to the 2013 American College of Cardiology/American Heart Association risk calculator. Among 298 evaluable women, mean age was 58.2 years (SD, 8.34), with 33% non-Hispanic White, 41% Hispanic, 9% non-Hispanic Black, 6% Asian, and 11% other/unknown race/ethnicity. About 98% of women met high-risk criteria for breast cancer, whereas 30% were high-risk for ASCVD. Mean 10-year risk of breast cancer was higher than mean 10-year risk of ASCVD (9.14% vs. 6.69%; P < 0.001). Among women who met high-risk criteria for both diseases, use of statins was higher compared with SERMs/AIs (58% vs. 21%; P < 0.001). Among women with AH or LCIS, statin use was higher compared with breast cancer chemoprevention among eligible women, despite having a higher mean risk of breast cancer than ASCVD.

PREVENTION RELEVANCE

Among women with high-risk breast lesions, mean absolute risk of breast cancer was higher compared with cardiovascular disease; however, statin use was significantly higher than chemoprevention. To address underutilization of breast cancer chemoprevention, these drugs should be placed in the context of medications used to prevent other chronic diseases.

Turning the Page on Breast Cancer in Ohio: Lessons learned from implementing a multilevel intervention to reduce breast cancer mortality among Black women

BACKGROUND

Turning the Page on Breast Cancer (TPBC) uses a multilevel approach to reduce breast cancer (BC) mortality among Black women. TPBC intervenes by (1) improving health care facilities' ability to conduct effective BC screening, follow-up, and treatment; (2) involving community-based organizations; and (3) providing education and personal risk information through a culturally relevant website. Ohio has among the worst BC mortality rates in the United States for Black women. TPBC is in its third year of providing targeted interventions in 12 Ohio counties with particularly high BC rates among Black women.

METHODS

TPBC enrolls health care facilities, collects organizational and patient data, and conducts key informant interviews to inform the provision of appropriate evidence-based interventions. TPBC engages Black communities through community-based organizations and social media advertising. The TPBC website offers BC information, connects Black women to community BC resources, and provides access to a risk-assessment tool.

RESULTS

TPBC has provided tailored information packets, evidence-based interventions, and systematic support for improving the tracking and follow-up of breast health care among patients in 10 clinical partnerships. The project has provided education at community events monthly since mid-2021. The TPBC website (http://endbreastcancerohio.org) is promoted through social media (primarily Facebook) and community events to reach Black women aged 25-70 years. To date, 4108 unique users have visited the website, of whom 15.9% completed the risk assessment.

CONCLUSIONS

Novel strategies are needed to address persistent disparities in BC outcomes among Black women. TPBC demonstrates the potential effectiveness of multiple methods of community-based, clinic-based, and web-based engagement.

PLAIN LANGUAGE SUMMARY

Turning the Page on Breast Cancer (TPBC) aims to reduce breast cancer mortality among Black women in Ohio by conducting multilevel, community-engaged interventions in 12 counties. Women are provided risk information and education at virtual and in-person community events and through a community-friendly website that was launched in November 2020. Almost 4000 women have visited the website, which offers community-targeted information, urges screening for individuals at elevated risk, and offers access to patient navigation services; 655 users have used a breast cancer risk-assessment tool on the site. Community-based organizations conduct educational efforts. TPBC partners with health care facilities, which are taught to improve their ability to conduct effective breast cancer screening, follow-up, and treatment. So far, TPBC has provided educational information, evidence-based intervention lists, tailored information packets, and ongoing quarterly support to partners in 10 counties. Evaluation will focus on aggregated data for screening and genetic testing referral at the clinic level.

Racial differences in prevention decision making among U.S. women at high risk of breast cancer: A qualitative study

PURPOSE

Women at high risk of breast cancer face complex decisions about how to manage those risks. Substantial gaps in current knowledge include how women make these decisions and how decision making may differ across sub-populations. Among these critical gaps are the questions of (a) whether racial differences exist between the experiences of high-risk women navigating breast cancer risk, and (b) what consequences those racial differences might have on women's ability to manage their cancer risks. The present study is designed to address these questions directly.

METHODS

Fifty semi-structured interviews were conducted with high-risk Black (n = 20) and white women (n = 30) between May 2015 and March 2016 in person in Ohio and by phone. Transcribed data were analyzed using grounded theory methods.

MAIN FINDINGS

Our analyses suggest that many of the core decision-making dynamics high-risk women navigate differ by race. The experiences of white and Black women in our study differ in terms of (a) contextualizing risk-how women make sense of their own breast cancer risk, the degree to which they worry about risk, and how they prioritize risk within the contexts of their broader lives; (b) conceptualizing risk management-how, how much, and from whom women learn about and conceptualize their options for preventing cancer and/or ensuring that cancer gets diagnosed early; and (c) constraints-the external barriers women face throughout their decision-making and risk-management processes. In sum, the Black women we interviewed reported feeling less well-situated to consider and cope actively with breast cancer risk, less well-informed about risk-management options, and more constrained in their use of these options.

CONCLUSIONS

High-risk women's accounts of the complex dynamics that shape breast cancer prevention decisions suggest that these dynamics vary substantially by race, such that Black women may experience disadvantages relative to whites.

Black Women's Perspectives on Breast Cancer Risk Assessment

PURPOSE

The aim of this study was to gather the perspectives of Black women on breast cancer risk assessment through a series of one-on-one interviews.

METHODS

The authors conducted a cross-sectional qualitative study consisting of one-on-one semistructured telephone interviews with Black women in Tennessee between September 2020 and November 2020. Guided by the Health Belief Model, qualitative analysis of interview data was performed in an iterative inductive and deductive approach and resulted in the development of a conceptual framework to depict influences on a woman's decision to engage with breast cancer risk assessment.

RESULTS

A total of 37 interviews were completed, and a framework of influences on a woman's decision to engage in breast cancer risk assessment was developed. Study participants identified several emerging themes regarding women's perspectives on breast cancer risk assessment and potential influences on women's decisions to engage with risk assessment. Much of women's decision context was based on risk appraisal (perceived severity of cancer and susceptibility of cancer), emotions (fear and trust), and perceived risks and benefits of having risk assessment. The decision was further influenced by modifiers such as communication, the risk assessment protocol, access to health care, knowledge, and health status. Perceived challenges to follow-up if identified as high risk also influenced women's decisions to pursue risk assessment.

CONCLUSIONS

Black women in this study identified several barriers to engagement with breast cancer risk assessment. Efforts to overcome these barriers and increase the use of breast cancer risk assessment can potentially serve as a catalyst to address existing breast cancer disparities. Continued work is needed to develop patient-centric strategies to overcome identified barriers.

Predicting breast cancer risk in a racially diverse, community-based sample of potentially high-risk women

BACKGROUND

Identifying women with high risk of breast cancer is necessary to study high-risk experiences and deliver risk-management care. Risk prediction models estimate individuals' lifetime risk but have rarely been applied in community-based settings among women not yet receiving specialized care. Therefore, we aimed: (1) to apply three breast cancer risk prediction models (i.e., Gail, Claus, and IBIS) to a racially diverse, community-based sample of women, and (2) to assess risk prediction estimates using survey data.

METHODS

An online survey was administered to women who were determined by a screening instrument to have potentially high risk for breast cancer. Risk prediction models were applied using their self-reported family and medical history information. Inclusion in the high-risk subsample required ≥20% lifetime risk per ≥1 model. Descriptive statistics were used to compare the proportions of women identified as high risk by each model.

RESULTS

N = 1053 women were initially eligible and completed the survey. All women, except one, self-reported the information necessary to run at least one model; 90% had sufficient information for >1 model. The high-risk subsample included 717 women, of which 75% were identified by one model only; 96% were identified by IBIS, 3% by Claus, <1% by Gail. In the high-risk subsample, 20% were identified by two models and 3% by all three models.

CONCLUSIONS

Assessing breast cancer risk using self-reported data in a community-based sample was feasible. Different models identify substantially different groups of women who may be at high risk for breast cancer; use of multiple models may be beneficial for research and clinical care.

Examining Associations between Source of Cancer Information and Mammography Behavior among Black Church-Going Women

Black women have a slightly lower breast cancer incidence rate than White women, but breast cancer mortality is approximately 40% higher among Black women than among White women. Early detection by mammography may improve survival outcomes. Outlets providing information on cancer and cancer screening often present data, including mammography recommendations, that are unreliable, accessible, and/or inconsistent. We examined associations between sources of cancer information and mammography behavior among Black church-going women. A logistic regression model was used to examine associations between self-reported preferred source of cancer information (provider, cancer organization, social network, internet, or other media (e.g., books, magazines)) and self-reported most recent source of cancer information (same categories as preferred sources), respectively, and having received a mammogram within the prior 12 months. Participants were 832 Black women over 40 years old, recruited from three churches in Houston, Texas. Data were collected in 2012. Overall, 55.41% of participants indicated their preferred source of cancer information was a provider, 21.88% the internet, 11.54% other media, 10.22% a cancer organization, and 0.96% their social network. In contrast, 17.88% of participants indicated their most recent source of cancer information was a provider, 63.02% the internet, 12.04% other media, 4.50% a cancer organization, and 2.55% their social network. About 70% of participants indicated receiving a mammogram in the prior 12 months. Results indicated that women who most recently sought information from the internet had lower odds of having a mammogram than those who most recently sought information from a provider (aOR: 0.546, CI95%: 0.336-0.886, p = 0.014). These results reveal an opportunity to advance health equity by encouraging Black church-going women to obtain cancer information from providers rather than from the internet as a method to enhance mammography use. These results also reveal an opportunity to investigate what modifiable social determinants or other factors prevent Black church-going women from seeking cancer information from their preferred source, which was a provider for the majority of the sample, and designing interventions to better actualize this preference.

Nurse practitioners have a vital role in achieving health equity in clinical cancer genetics

Long-standing and persistent racial inequities exist in cancer prevention, diagnosis, treatment, and outcomes. Genetic medicine has the promise to significantly advance the identification of at-risk individuals and facilitate prevention, early detection, and treatment of cancer. Genetic testing is increasingly becoming incorporated into the screening-to-treatment continuum of care for cancer. Although genetic technologies are relatively new to the cancer care landscape, racial inequities already exist in awareness, access, referral, and uptake. Nurses play a vital role in achieving health equity, but success requires that nurses understand, recognize and take action to overcome the factors that have fostered health inequities.

Association of Population Screening for Breast Cancer Risk With Use of Mammography Among Women in Medically Underserved Racial and Ethnic Minority Groups

IMPORTANCE

Black women bear a disproportionate burden of breast cancer mortality in the US, in part due to inequities in the use of mammography. Population screening for breast cancer risk in primary care is a promising strategy for mitigating breast cancer disparities, but it is unknown whether this strategy would be associated with increased mammography rates in underserved women of racial and ethnic minority groups.

OBJECTIVE

To examine whether providing individualized breast cancer risk estimates is associated with an increase in the rate of screening mammography.

DESIGN, SETTING, AND PARTICIPANTS

A cohort study was conducted in women receiving individualized risk estimates as part of routine primary health care at federally qualified health centers in medically underserved communities in Chicago, Illinois. The study was conducted from November 5, 2013, to December 19, 2014, with data acquisition completed on March 5, 2017; data analysis was performed from December 30, 2020, to February 2, 2021. A total of 347 women aged 25 to 69 years without a personal history of breast cancer presenting for an annual visit with their primary care clinician were enrolled.

EXPOSURES

Breast cancer risk estimates were obtained with validated risk assessment tools as a standard component of the clinic check-in process. One of 4 women at average risk and all women at high risk were invited to participate in the study.

MAIN OUTCOMES AND MEASURES

The primary outcome was the mammography rate during 18 months of usual care compared with the rate during 18 months after implementation of risk assessment.

RESULTS

Of the 347 women enrolled, 188 were age-eligible for mammography and were included in the analysis (mean [SD] age, 50.8 [7.04] years); 70 women (37.2%) were Hispanic, 114 (60.6%) were non-Hispanic African American, and 4 (2.1%) were from other racial and ethnic groups (4 non-Hispanic White women). Ninety-eight women (52.1%) had an average risk of developing breast cancer and 90 (47.9%) were at high risk. Overall, there was a nonsignificant increase in the mammography rate, from 38.8% during usual care to 48.9% following implementation of risk assessment (odds ratio, 1.37; 95% CI, 0.92-2.03). In preplanned subgroup analysis, the mammography rate among women at high risk was significantly higher after vs before risk assessment (51.1% vs 36.6%; odds ratio, 1.88; 95% CI, 1.10-3.23).

CONCLUSIONS AND RELEVANCE

In this study, providing individualized breast cancer risk estimates as a component of primary health care in federally qualified health centers was associated with increased use of mammography among women of racial and ethnic minority groups who were at high risk. Implementation of this approach in underserved communities could promote equity in the use of mammography and reduce racial disparities in breast cancer mortality. This strategy warrants further investigation.

Understanding low chemoprevention uptake by women at high risk of breast cancer: findings from a qualitative inductive study of women's risk-reduction experiences

BACKGROUND

Chemoprevention is one of several methods that have been developed to help high-risk women reduce their risk of breast cancer. Reasons for the low uptake of chemoprevention are poorly understood. This paper seeks a deeper understanding of this phenomenon by drawing on women's own narratives about their awareness of chemoprevention and their risk-related experiences.

METHODS

This research is based on a parent project that included fifty in-depth, semi-structured interviews with a purposive sample of African American and White women at elevated risk of breast cancer. This specific study draws on the forty-seven interviews conducted with women at high or severe risk of breast cancer, all of whom are eligible to use chemoprevention for breast cancer risk-reduction. Interviews were analyzed using grounded theory methods.

RESULTS

Forty-five percent of participants, and only 21% of African American participants, were aware of chemoprevention options. Women who had seen specialists were more likely to be aware, particularly if they had ongoing specialist access. Aware and unaware women relied on different types of sources for prevention-related information. Those whose main source of information was a healthcare provider were more likely to know about chemoprevention. Aware women used more nuanced information gathering strategies and worried more about cancer. Women simultaneously considered all risk-reduction options they knew about. Those who knew about chemoprevention but were reluctant to use it felt this way for multiple reasons, having to do with potential side effects, perceived extreme-ness of the intervention, similarity to chemotherapy, unknown information about chemoprevention, and reluctance to take medications in general.

CONCLUSIONS

Lack of chemoprevention awareness is a critical gap in women's ability to make health-protective choices. Future research in this field must consider complexities in both women's perspectives on chemoprevention and the reasons they are reluctant to use it.

Financial constraints on genetic counseling and further risk-management decisions among U.S. women at elevated breast cancer risk

Clinical guidelines recommend that women at high risk of breast cancer should consider various risk-management options, which remain widely underutilized. We conducted semi-structured, qualitative interviews with 50 high-risk women to understand how financial constraints affect use of genetic counseling, genetic testing, and further risk-management decisions. Inductive analyses revealed three categories of health-related financial constraint: (a) lack of insurance, (b) underinsurance, and (c) other financial constraints (e.g., medical debt, raising children, managing comorbidities). Various breast cancer risk-management actions were limited by these financial constraints, including genetic counseling, genetic testing, enhanced screening, and prophylactic surgeries. Women's narratives also identified complex relationships between financial constraint and perceptions of healthcare providers and insurance companies, particularly as related to bias, price transparency, and potential genetic discrimination. Results from this study have implications for further research and expansion of genetic counseling services delivery to more economically and racially diverse women.
