RESUMO

BACKGROUND: Populations of African American or Black women have persistently higher breast cancer mortality than the overall US population, despite having slightly lower age-adjusted incidence. METHODS: Three Cancer Intervention and Surveillance Modeling Network simulation teams modeled cancer mortality disparities between Black female populations and the overall US population. Model inputs used racial group-specific data from clinical trials, national registries, nationally representative surveys, and observational studies. Analyses began with cancer mortality in the overall population and sequentially replaced parameters for Black populations to quantify the percentage of modeled breast cancer morality disparities attributable to differences in demographics, incidence, access to screening and treatment, and variation in tumor biology and response to therapy. RESULTS: Results were similar across the 3 models. In 2019, racial differences in incidence and competing mortality accounted for a net ‒1% of mortality disparities, while tumor subtype and stage distributions accounted for a mean of 20% (range across models = 13%-24%), and screening accounted for a mean of 3% (range = 3%-4%) of the modeled mortality disparities. Treatment parameters accounted for the majority of modeled mortality disparities: mean = 17% (range = 16%-19%) for treatment initiation and mean = 61% (range = 57%-63%) for real-world effectiveness. CONCLUSION: Our model results suggest that changes in policies that target improvements in treatment access could increase breast cancer equity. The findings also highlight that efforts must extend beyond policies targeting equity in treatment initiation to include high-quality treatment completion. This research will facilitate future modeling to test the effects of different specific policy changes on mortality disparities.

RESUMO

Over the past 2 decades, population simulation modeling has evolved as an effective public health tool for surveillance of cancer trends and estimation of the impact of screening and treatment strategies on incidence and mortality, including documentation of persistent cancer inequities. The goal of this research was to provide a framework to support the next generation of cancer population simulation models to identify leverage points in the cancer control continuum to accelerate achievement of equity in cancer care for minoritized populations. In our framework, systemic racism is conceptualized as the root cause of inequity and an upstream influence acting on subsequent downstream events, which ultimately exert physiological effects on cancer incidence and mortality and competing comorbidities. To date, most simulation models investigating racial inequity have used individual-level race variables. Individual-level race is a proxy for exposure to systemic racism, not a biological construct. However, single-level race variables are suboptimal proxies for the multilevel systems, policies, and practices that perpetuate inequity. We recommend that future models designed to capture relationships between systemic racism and cancer outcomes replace or extend single-level race variables with multilevel measures that capture structural, interpersonal, and internalized racism. Models should investigate actionable levers, such as changes in health care, education, and economic structures and policies to increase equity and reductions in health-care-based interpersonal racism. This integrated approach could support novel research approaches, make explicit the effects of different structures and policies, highlight data gaps in interactions between model components mirroring how factors act in the real world, inform how we collect data to model cancer equity, and generate results that could inform policy.

RESUMO

Genetic counseling and testing (GCT) inform cancer management for persons at risk for hereditary breast and ovarian cancer (HBOC). Community-based organizations (CBOs) may play a role in identifying at-risk Latinx individuals to connect them to GCT but data are lacking. Two academic centers and their four CBO partners planned to implement a validated questionnaire for HBOC risk screening ("HBOC risk screening tool"). This study aimed to assess CBO's preferences for HBOC risk screening tools, as well as the barriers and facilitators anticipated for future implementation. Pre-implementation focus groups were conducted with CBO's staff. Discussions centered on current practices to identify and refer at-risk patients. During the discussion, staff were asked to select one out of five validated HBOC risk screening tools to implement and to discuss anticipated barriers/facilitators for implementation. The four focus groups were coded and qualitative analyzed following the Consolidated Framework for Implementation Research (CFIR) and Health Equity domains. All CBOs chose the Family History Screen 7 (FHS-7). Participants (N = 35) highlighted how the FHS-7 was easy to adapt to better fit the target population and changing guidelines. They had positive attitudes toward implementing the screening tool, stressed how the culture of the organization positioned them to reach the target population, and noted barriers in different CFIR domains (e.g., low knowledge about HBOC and GCT referrals; scarce available resources). Participants pointed to barriers related to health equity domains including limited access to GCT and follow-up care for uninsured and underinsured populations, challenges obtaining accurate family history, and immigration-related barriers. CBOs highlighted the importance of partnering with other stakeholders to overcome barriers. Findings emphasize the need to develop multi-level implementation strategies to overcome barriers and leverage facilitators. This study can inform the development of implementation toolkits for CBOs to implement HBOC screening tools to advance health equity.

RESUMO

Disparities in colorectal cancer (CRC) incidence and mortality persist in rural and underserved communities. Our Community Outreach and Engagement (COE) activities are grounded in a bi-directional Community-to-Bench model in which the National Outreach Network Community Health Educator (NON CHE) Screen to Save (S2S) initiative was implemented. In this study, we assessed the impact of the NON CHE S2S in rural and underserved communities. Descriptive and comparative analyses were used to examine the role of the NON CHE S2S on CRC knowledge and CRC screening intent. Data included demographics, current CRC knowledge, awareness, and future CRC health plans. A multivariate linear regression was fit to survey scores for CRC knowledge. The NON CHE S2S engaged 441 participants with 170 surveys completed. The difference in participants' CRC knowledge before and after the NON CHE S2S intervention had an overall mean of 0.92 with a standard deviation of 2.56. At baseline, White participants had significantly higher CRC knowledge scores, correctly answering 1.94 (p = 0.007) more questions on average than Black participants. After the NON CHE S2S intervention, this difference was not statistically significant. Greater than 95% of participants agreed that the NON CHE S2S sessions impacted their intent to get screened for CRC. Equity of access to health information and the health care system can be achieved with precision public health strategies. The COE bi-directional Community-to-Bench model facilitated community connections through the NON CHE and increased awareness of CRC risk reduction, screening, treatment, and research. The NON CHE combined with S2S is a powerful tool to engage communities with the greatest health care needs and positively impact an individual's intent to "get screened" for CRC.

RESUMO

PURPOSE: Black women often experience poorer breast cancer-related outcomes and higher mortality than white women. A contributor to this disparity may relate to the disproportionate burden of cancer treatment-related cardiovascular (CV) toxicities. The objective of this review is to identify studies that report racial differences in CV toxicity risk. METHODS: Medline and Embase were searched for studies that assessed CV toxicities as the outcome(s) and included Black and White women with breast cancer. Studies were selected based on inclusion/exclusion criteria and through the use of multiple reviewers. RESULTS: The review included 13 studies following a review of 409 citations and 49 full-text articles. All studies were retrospective and 8/13 utilized data from the Surveillance, Epidemiology, and End Results-Medicare linked database. Trastuzumab was the most frequently studied treatment. The proportion of Black women in these studies ranged from 5.5 to 63%. A majority of studies reported a higher risk of CV toxicity amongst Black women when compared to white women (93%). Black women had up to a two times higher risk of CV toxicity (HR, 2.73 (CI, 1.24 to 6.01)) compared to white women. Only one study evaluated the role of socioeconomic factors in explaining racial differences in CV toxicity; however, the disparity remained even after adjusting for these factors. CONCLUSIONS: There is a critical need for more longitudinal studies that evaluate multilevel factors (e.g., psychosocial, biological) that may help to explain this disparity. IMPLICATIONS FOR CANCER SURVIVORS: Black cancer survivors may require additional surveillance and mitigation strategies to decrease disproportionate burden of CV toxicities.

RESUMO

Social Determinants of Health (SDOH) impact health outcomes; thus, a pilot to screen for important SDOH domains (food, housing, and transportation) and address social needs in hospitalized patients was implemented in an urban safety-net academic medical center. This study describes the pilot implementation and examines patient characteristics associated with SDOH-related needs. An internal medicine unit was designated as a pilot site. Outreach workers approached eligible patients (n = 1,135) to complete the SDOH screening survey at time of admission with 54% (n = 615) completing the survey between May 2019 and July 2020. Data from patient screening survey and electronic health records were linked to allow for examination of associations between SDOH needs for food, housing, and transportation and various demographic and clinical characteristics of patients in multivariate logistic regression models. Of 615 screened patients, 45% screened positive for any need. Of 275 patients with needs, 33% reported needs in 2, and 34% - in 3 domains. Medicaid beneficiaries were more likely than patients with private health insurance to screen positive for 2 and 3 needs; Black patients were more likely than White patients to screen positive for 1 and 3 needs; Patients with no designated primary care physician status screened positive for 1 need; Patients with a history of substance use disorder screened positive for all 3 needs. SDOH screening assisted in addressing social risk factors of inpatients, informed their discharge plans and linkage to community resources. SDOH screening demonstrated significant correlations of positive screens with race/ethnicity, insurance type, and certain clinical characteristics.

RESUMO

Over the last year, COVID-19 has emerged as a highly transmissible and lethal infection. As we address this global pandemic, its disproportionate impact on Black, Indigenous, and Latinx communities has served to further magnify the health inequities in access and treatment that persist in our communities. These sobering realities should serve as the impetus for reexamination of the root causes of inequities in our health system. An increased commitment to strategic partnerships between academic and nonacademic health systems, industry, local communities, and policy-makers may serve as the foundation. Here, we examine the impact of the recent COVID-19 pandemic on health care inequities and propose a strategic roadmap for integration of clinical and translational research into our understanding of health inequities.

RESUMO

Objective: Inclusion of women in biomedical cancer research have the potential to close gaps in cancer health disparities and improve adjuvant therapies for women; yet samples needed to advance this area of science are lacking. We developed low-cost educational recruitment strategies to increase our collection of biospecimens from women. Materials and Methods: Women diagnosed with hormone receptor positive (HR+) breast cancer that initiated hormonal therapy were recruited from three integrated health systems. The analytical sample (n = 144) consisted of women who consented but did not return a saliva sample within 1 year of the initial assessment (baseline). Brief informational recruitment materials were developed via published literature and preliminary data. Women received recruitment materials, which included a personalized information letter, a colorful low-literacy instruction sheet, a postage-paid envelope, and collection kits. We evaluated intervention materials and performed descriptive and bivariate statistics to describe factors associated with biospecimen donation. Results: Of the total sample, 61% were white and 34% were black. Overall, 29 surveys (20%) and 25 (17%) saliva kits were returned. Women found the materials helpful and easy to read and understand. Women with higher levels of functional well-being and lower ratings of religiosity were more likely to return biospecimens (p < 0.005) after receiving enhanced materials. Conclusion: This article provides recruitment strategies to enhance biospecimen samples among women. Receipt of brief informational print materials inclusive of personalized messages enhanced our outreach strategies and increased our overall biospecimen provision rate by 17%. The inclusion of messages with a focus on spirituality and other cultural messages may further increase biospecimen provision in racial/ethnic diverse groups of women; however, further study is needed to support this claim.

RESUMO

Building a culture of precision public health requires research that includes health delivery model with innovative systems, health policies, and programs that support this vision. Health insurance mandates are effective mechanisms that many state policymakers use to increase the utilization of preventive health services, such as colorectal cancer screening. This study estimated the effects of health insurance mandate variations on colorectal cancer screening post Affordable Care Act (ACA) era. The study analyzed secondary data from the Behavioral Risk Factor Surveillance System (BRFSS) and the NCI State Cancer Legislative Database (SCLD) from 1997 to 2014. BRFSS data were merged with SCLD data by state ID. The target population was U.S. adults, age 50 to 74, who lived in states where health insurance was mandated or nonmandated before and after the implementation of ACA. Using a difference-in-differences (DD) approach with a time-series analysis, we evaluated the effects of health insurance mandates on colorectal cancer screening status based on U.S. Preventive Services Task Force guidelines. The adjusted average marginal effects from the DD model indicate that health insurance mandates increased the probability of up-to-date screenings versus noncompliance by 2.8% points, suggesting that an estimated 2.37 million additional age-eligible persons would receive a screening with such health insurance mandates. Compliant participants' mean age was 65 years and 57% were women (n = 32,569). Our findings are robust for various model specifications. Health insurance mandates that lower out-of-pocket expenses constitute an effective approach to increase colorectal cancer screenings for the population, as a whole. PREVENTION RELEVANCE: The value added includes future health care reforms that increase access to preventive services, such as CRC screening, are likely with lower out-of-pocket costs and will increase the number of people who are considered "up-to-date". Such policies have been used historically to improve health outcomes, and they are currently being used as public health strategies to increase access to preventive health services in an effort to improve the nation's health.

RESUMO

PURPOSE: The last fifteen years has seen a rising proportion of women who are eligible for breast conserving therapy (BCT) choosing mastectomy despite equivalent survival in early-stage breast cancer. We aim to explore potential racial differences in the association of surgical choice with subsequent patient-reported satisfaction outcomes. METHODS: Women who were within one year of diagnosis with hormone receptor (HR)-positive breast cancer were asked the Short Version of Patient Satisfaction Questionnaire (PSQ-18), which assesses their overall satisfaction with their medical care. We conducted bivariate analyses, including paired t-tests, to clarify differences in these patient-reported factors by surgical choice and race. Multivariable linear regression models were used to adjust for clinical and demographic control variables. RESULTS: For the sample of 279 women who underwent definitive surgery, women who received a mastectomy had lower levels of overall satisfaction, 71 vs. 75 (out of 90) (p = .001). In stratifying this relationship by race, the difference in total satisfaction score was largest among Black women (69 among mastectomy patients vs. 75 among BCT patients; p = 0.016). On multivariable linear regression, Black race and mastectomy status (together) exhibited a significantly large negative association with total satisfaction score, with negative associations across all domains of the PSQ-18. CONCLUSION: Despite the high prevalence of mastectomy among Black women with early-stage, HR-positive breast cancer, this population is more likely to report lower levels of patient satisfaction compared to patients receiving BCT. These findings suggest there may be potential racial differences in the psychosocial consequences of surgical choice.

RESUMO

Disparities in genetic cancer risk assessment (GCRA) uptake persist between Latinas and Non-Hispanic Whites. This study utilized a mental model approach to interview 20 Latinas (10 affected, 10 unaffected) at increased risk for hereditary breast and ovarian cancer (HBOC). Participants were asked about their knowledge and perceptions of GCRA, HBOC, risk, benefits, motivators, barriers, challenges, and experiences with GCRA. Using the Consensual Qualitative Analysis Framework, two authors independently coded the interviews and applied the final codes upon consensus. Additionally, interviews were coded to identify whether participants spontaneously brought up certain topics without a prompt. Findings identified multiple barriers and facilitators to GCRA uptake in this population, including patient level psychosocial/cultural factors (e.g., limited knowledge, worry about relatives' risk) and healthcare system factors (e.g., receiving no referrals). There were notable differences in awareness and knowledge between affected and unaffected women (e.g., genetic testing awareness), as well as knowledge gaps that were evident in both groups (e.g., age of diagnosis as a risk factor). To reduce disparities in GCRA uptake, interventions should address identified facilitators and barriers. Differences in knowledge and awareness between affected and unaffected women support the development of targeted interventions that address specific knowledge gaps. This study was registered in ClinicalTrials.gov (NCT03075540) by Alejandra Hurtado de Mendoza, Ph.D.

RESUMO

Medical mistrust measures have not been validated in Latino immigrants. This study examined the psychometric properties of the Medical Mistrust Index and its association with health care satisfaction in a sample of Latina immigrants. Participants were 168 self-identified Latinas ≥40 years old. Women were recruited from three Latino-serving health clinics and through a Latino radio program. A bilingual interviewer administered the Medical Mistrust Index in Spanish along with items pertaining to sociodemographic and health care factors. Principal component extraction method was used to evaluate internal consistency reliability to examine Medical Mistrust Index underlying factors. Construct validity was assessed by analyzing the relationship between the Medical Mistrust Index with three related measures (racism, discrimination, trust in doctors). To assess the criterion validity of the Medical Mistrust Index, a logistic regression model examined whether medical mistrust was associated with Latina women's satisfaction with health care controlling for sociodemographic and health care factors. Participants were 51 years old on average, around half had completed High school or less and were uninsured. Most were monolingual Spanish speakers. Two factors: competence and suspicion explained 40% of the total Medical Mistrust Index variance. Internal consistency was favorable and construct validity was supported. Results support the reliability and validity of the Medical Mistrust Index and its association with Latina's satisfaction with health care.

RESUMO

OBJECTIVE: To evaluate awareness and acceptability of population-based BRCA testing among an unselected population of women presenting for annual gynecologic health assessment, with secondary objective to determine if a racial disparity exists in acceptability and awareness of this screening strategy. METHODS: Women presenting for routine gynecologic care in an outpatient setting of a single academic institution were anonymously surveyed. Survey collected age, self-identified race and ethnicity, education level, personal and family history of breast and/or ovarian cancer (BOC), awareness and interest, and willingness to pay out of pocket for testing. Responses were compared with bivariate and multivariate analysis. RESULTS: Interest in testing was expressed in 150 of 301 (45.1%) of participants. Women with a family history of BOC were more likely to be interested in testing than those without (OR = 1.9 (1.0-3.6)). Interest in testing was associated willingness to pay (OR = 3.3 (1.7-6.4)). Higher education level was associated with awareness of testing (OR = 9.9 (2.0-49.7)). Interest in testing was similar between racial groups, but awareness and willingness to pay for testing were higher among White women. Multivariate analysis with adjustment for education level confirmed that Black and Hispanic women were less likely to have awareness of genetic testing compared to White women and non-Hispanic Women, respectively (OR = 0.11 (0.05-0.3); OR = 0.10 (0.01-0.8)). CONCLUSIONS: Interest in genetic testing among women in the general population is high. Despite interest, awareness of BRCA is poor among Black and Hispanic women even when adjusting for education level.

RESUMO

BACKGROUND: Adjuvant endocrine therapy (AET) is a critical therapy in that it improves survival in women with hormone receptor-positive (HR+) breast cancer (BC), but adherence to AET is suboptimal. The purpose of this study was to fill scientific gaps about predictors of adherence to AET among black and white women diagnosed with BC. OBJECTIVE: To assess AET adherence in black and white insured women using multiple measures, including one that uses an innovative statistical approach. METHODS: Black and white women newly diagnosed with HR+ BC were identified from 2 health maintenance organizations. Pharmacy records captured the type of oral AET prescriptions and all fill dates. Multivariable logistic regression was used to identify predictors of adherence defined in terms of proportion of days covered (PDC; ≥ 80%) and medication gap of ≤ 10 days. A zero-inflated negative binomial (ZINB) regression model was used to identify variables associated with the total number of days of medication gaps. RESULTS: 1,925 women met inclusion criteria. 80% were PDC adherent (> 80%); 44% had a medication gap of ≤ 10 days; and 24% had no medication gap days. Race and age were significant in all multivariable models. Black women were less likely to be adherent based on PDC than white women (OR = 0.72, 95% CI = 0.57-0.90, P < 0.01), and they were less likely to have a medication gap of ≤ 10 days (OR = 0.65, 95% CI = 0.54-0.79, P < 0.001). Women aged 25-49 years were less likely to be PDC adherent than women aged 65-93 years (OR = 0.65, 95% CI = 0.48-0.87, P < 0.001). In the ZINB model, women were without their medication for an average of 37 days (SD = 50.5). CONCLUSIONS: Racial disparities in adherence to AET in the study highlight a need for interventions among insured women. Using various measures of adherence may help better understand this multidimensional concept. There might be benefits from using both more common dichotomous measures (e.g., PDC) and integrating novel statistical approaches to allow tailoring adherence to patterns within a specific sample.

RESUMO

Studies indicate that Black patients report higher medical mistrust compared to their White counterparts. However, little is known about factors associated with higher medical mistrust among Black breast cancer patients. We examined predictors of medical mistrust and relationships between medical mistrust, subscales of mistrust, and process of care factors to identify opportunities to promote positive healthcare interactions between the trustees (e.g., providers) and Black breast cancer patients, or the trustors. A secondary analysis was conducted of survey data from 210 Black women with confirmed diagnosis of invasive breast cancer. Participants completed telephone surveys consisting of questions pertaining to sociodemographics, attitudes, and beliefs about medical care and breast cancer treatments. Multiple linear regression determined factors associated with medical mistrust and mistrust subscales. Most participants (61%) were over the age of 50 and currently single (64.8%). Women with greater medical mistrust reported less satisfaction with the trustee's technical ability (p < 0.0001) and greater satisfaction with their own propensity to access care (p < 0.05). Additionally, women with public insurance demonstrated greater mistrust (p < 0.01) and suspicion (p < 0.05) than women with private insurance, and women with less education reported greater perceived discrimination than women who have at least a bachelor's degree. Findings from this study may inform future endeavors to educate providers on ways to effectively interact with and treat Black breast cancer patients. Opportunities to develop interventions that address and tackle issues of mistrust as reported by Black patients may contribute to ongoing efforts to reduce health disparities.

RESUMO

The benefits of genetic counseling and testing for hereditary breast and/or ovarian cancer (HBOC) are well documented; however, Black women are less likely to use these services compared to White women. Mistrust of the medical system has been associated with Black women's use of genetic counseling and testing (GCT). However, relatively little is known about the correlates of medical mistrust in Black women at increased risk of HBOC. In this study, we examined the prevalence and predictors of medical mistrust in 94 Black women at-risk of HBOC. Most women were married (48.7%) and had at least some collegiate education (57.1%). While no predisposing characteristics were significantly related to medical mistrust, bivariate analysis indicated significant relationships between mistrust and fatalism (p=0.04), perceptions of discrimination in the healthcare setting (p=0.01), and self-efficacy in obtaining GCT (p=0.01). Multivariable analysis revealed that women who reported more discriminatory experiences and women with less confidence in obtaining GCT expressed greater medical mistrust. Multilevel approaches are needed to address psychosocial factors associated with feelings of mistrust. Future efforts must not solely focus on educating women on the importance of and need for GCT; addressing structural barriers, such as patient-provider interactions, that contribute to mistrust must become a priority.

RESUMO

The Comprehensive Cancer Network (NCCN) recommends genetic cancer risk assessment (GCRA) referral to women at high risk of hereditary breast and ovarian cancer. Latinas affected by breast cancer have the second highest prevalence of BRCA1/2 mutations after Ashkenazi Jews. Compared to non-Hispanic Whites, Latinas have lower GCRA uptake. While some studies have identified barriers for GCRA use in this population, few studies have focused on health care providers' perspectives. The purpose of the study was to examine providers' perceptions of barriers and facilitators for at-risk Latina women to participate in GCRA and their experiences providing services to this population. We conducted semi-structured interviews with 20 healthcare providers (e.g., genetic counselors, patient navigators) recruited nationally through snowballing. Interviews were transcribed. Two coders independently coded each interview and then met to reconcile the codes using Consensual Qualitative Research guidelines. Providers identified several facilitators for GCRA uptake (e.g., family, treatment/prevention decisions) and barriers (e.g., cost, referrals, awareness, stigma). Genetic counselors described important aspects to consider when working with at-risk Latina including language barriers, obtaining accurate family histories, family communication, and testing relatives who live outside the US. Findings from this study can inform future interventions to enhance uptake and quality of GCRA in at-risk Latina women to reduce disparities.

RESUMO

The aim of this study was to determine the impact of race and socioeconomic status on breast tumor clinicopathological features and survival outcomes. This study used breast cancer data from the Washington D.C. Cancer Registry (2000- 2010). Logistic regression and survival analysis assessed the association between race, socioeconomic (SES) variables, clinicopathological variables, recurrence-free survival and overall survival. African American (AA) breast cancer patients had an increased risk for stage III, ER-, and PR-breast cancer compared with White and Hispanic breast cancer patients. Additionally, D.C. geographical areas of lower socioeconomic status had higher incidences of stage III and stage IV breast cancer. A nested analysis demonstrated that AAs with higher median incomes compared with AAs with lower incomes revealed no differences for clinicopathological variables, nor were differences found between overall and recurrence-free survival. This study suggests that the biology of breast cancer in AAs could be driving breast cancer disparities.

RESUMO

PURPOSE: African-American women (AAW) are more likely to be metabolically unhealthy than White women (WW). Metabolic syndrome (MetS) is associated with increased breast cancer risk and mortality from breast cancer is greater in AAW compared to WW. Data show MetS affects health-related quality of life (HRQoL). Exercise studies report improvements in MetS, however, no study to date has examined HRQoL in metabolically unhealthy AAW enrolled in an exercise trial. METHODS: This report examined the effect of a 6-month, 3-arm (supervised exercise, home-based exercise, control) randomized exercise controlled trial on HRQoL among 213 obese, metabolically unhealthy, postmenopausal AAW at high risk for breast cancer. RESULTS: Certain baseline participant characteristics were related to baseline HRQoL dimensions. The "exercise group" (supervised group combined with the home-based group) showed significantly greater improvement in health change scores (M = 13.6, SD = 3.1) compared to the control group (M = 0.7, SD = 4.4) (p = 0.02) over the 6-month study period. There were no significant differences in HRQoL change scores between the 3 study groups, however, although non-significant, data indicated most HRQoL change scores were more favorable in the supervised group. CONCLUSION: While significant improvement occurred in health change scores in the combined supervised and home-based group compared to the control group, we did not observe any significant differences on HRQoL change scores between all three study groups. However, while non-significant, there was a trend for more favorable HRQoL change scores in the supervised group versus the home-based and control groups. Additional research is needed to further explore this topic.

RESUMO

Adjuvant hormone therapy contributes to reductions in recurrence and mortality for women with hormone receptor-positive breast cancer. However, adherence to hormone therapy is suboptimal. This is the first systematic literature review examining interventions aimed at improving hormone therapy adherence. Researchers followed the PRISMA guidelines. PubMed-Medline, CINAHL, PsychInfo, Ovid-Medline, and EMBASE were searched for behavioral interventions that aimed to enhance adherence to adjuvant hormone therapy in breast cancer survivors. A total of 376 articles were screened for eligibility. Five articles met the study criteria. All interventions presented adherence outcomes after 1-year follow-up. None significantly enhanced adherence compared to the usual care in the primary analysis (odds ratios ranged from 1.03 to 2.06 for adherence and from 1.11 to 1.18 for persistence). All studies targeted patients, and only 3 studies included postmenopausal breast cancer patients. Three tested the same intervention consisting of educational materials. Only one was conducted in the United States. Only one reported participants' ethnicity. Overall, it was unclear whether the studies contained bias. The use of different terminology and operationalization of adherence made comparisons challenging. Interventions to improve adherence to adjuvant hormone therapy in US breast cancer populations that include survivors who are ethnically diverse, premenopausal, and receiving tamoxifen therapy are necessary to inform future interventions. Adoption of consistent adherence definitions/measurements will provide a clearer framework to consolidate aggregate findings. Given the limited efficacy of tested interventions, it is important to engage oncologists and researchers to develop approaches that target different components associated with hormone therapy adherence, such as doctor-patient communication or social support.
