Racial and ethnic disparities in awareness of genetic testing for cancer risk

Treating new-onset cognitive complaints after risk-reducing salpingo-oophorectomy: A randomized controlled crossover trial of lisdexamfetamine

OBJECTIVE

To determine whether the psychostimulant lisdexamfetamine improves subjective and objective measures of cognitive functioning among women genetically at-risk for cancer who have undergone risk-reducing salpingo-oophorectomy and report new-onset executive functioning difficulties.

METHODS

69 participants were assigned to a randomized controlled crossover trial with 6-week trials of active medication (lisdexamfetamine) and placebo, separated by a minimum 2-week washout in an intent-to-treat framework (clinical trial registration number: NCT03187353). At trial baseline, midpoint, and endpoint, participants completed a self-report measure of executive functioning (Brown Attention Deficit Disorder Scale). At study baseline and trial endpoint, participants completed sustained attention, attention/working memory, and verbal learning/memory cognitive tasks. Side effects were assessed at 2, 3, 4, and 6 weeks for each trial.

RESULTS

From trial baseline to trial endpoint, lisdexamfetamine - relative to placebo - significantly improved total scores on the self-report Brown Attention Deficit Disorder Scale (and scores on four of five subdomains) as well as attention and working memory performance. Significantly more participants endorsed side effects across the lisdexamfetamine trial versus placebo; however, trial completion rates were similar, indicating that lisdexamfetamine was nonetheless well-tolerated.

CONCLUSIONS

Lisdexamfetamine improved both subjective and objective measures of attention and working memory and could offer women experiencing cognitive difficulties post-risk-reducing salpingo-oophorectomy an alternative therapeutic option.

Oncologists' perceptions of tumor genomic profiling and barriers to communicating secondary hereditary risks to African American cancer patients

BACKGROUND

Tumor genomic profiling (TGP) identifies targets for precision cancer treatments, but also secondary hereditary risks. Oncologists are poorly trained to communicate the results of TGP, especially among patients with lower health literacy, poorer genetics knowledge, and higher mistrust. African American (AA) patients are especially vulnerable to poor understanding due to significant cancer disparities and lower uptake of TGP. The goal of this research is to inform the development of an internet-based brief educational support for oncologists to prepare them to provide better decisional support related to TGP for their AA cancer patients.

METHODS

This mixed-methods study used semi-structured interviews of oncologists to inform development of an online survey with a convenience sample of US-based oncologists (n = 50) to assess perceptions of the challenges of TGP and communicating results to AA patients.

RESULTS

Most interviewed oncologists felt it was important to consider racial/cultural differences when communicating about hereditary risks. Cost, family dynamics, discrimination concerns, and medical mistrust were identified as particularly salient. Survey respondents' views related to AAs and perceptions of TGP were strongly associated with years since completing training, with recent graduates expressing stronger agreement with statements identifying barriers/disadvantages to TGP for AA patients.

CONCLUSIONS

Oncologists who had more recently completed training expressed more negative perceptions of TGP and more perceived challenges in communicating about TGP with their AA patients. Focused training for oncologists that addresses barriers specific to AAs may be helpful in supporting improved communication about TGP and improved decisional support for AA patients with cancer considering TGP to evaluate their tumors.

Disparities in genetic testing for breast cancer among black and Hispanic women in the United States

Women from racial and ethnic minorities are at a higher risk for developing breast cancer. Despite significant advancements in breast cancer screening, treatment, and overall survival rates, disparities persist among Black and Hispanic women. These disparities manifest as breast cancer at an earlier age with worse prognosis, lower rates of genetic screening, higher rates of advanced-stage diagnosis, and higher rates of breast cancer mortality compared to Caucasian women. The underutilization of available resources, such as genetic testing, counseling, and risk assessment tools, by Black and Hispanic women is one of many reasons contributing to these disparities. This review aims to explore the racial disparities that exist in genetic testing among Black and Hispanic women. Barriers that contribute to racial disparities include limited access to resources, insufficient knowledge and awareness, inconsistent care management, and slow progression of incorporation of genetic data and information from women of racial/ethnic minorities into risk assessment models and genetic databases. These barriers continue to impede rates of genetic testing and counseling among Black and Hispanic mothers. Consequently, it is imperative to address these barriers to promote early risk assessment, genetic testing and counseling, early detection rates, and ultimately, lower mortality rates among women belonging to racial and ethnic minorities.

Genetic Testing for Cancer Risk and Perceived Importance of Genetic Information Among US Population by Race and Ethnicity: a Cross-sectional Study

BACKGROUND

Genetic testing can help determine the risk of many cancers and guide cancer prevention and treatment plans. Despite increasing concern about disparities in precision cancer medicine, public knowledge and cancer genetic testing by race and ethnicity have not been well investigated.

METHODS

We analyzed data from the 2020 Health Information National Trends Survey in 2022. Self-reported cancer genetic testing (e.g., Lynch syndrome, BRCA1/2) knowledge and utilization were compared by race and ethnicity. Perceived importance of genetic information for cancer care (prevention, detection, and treatment) was also examined in relation to the uptake of cancer genetic testing. Multivariable logistic regression models were employed to examine factors associated with knowledge and genetic testing to calculate predicted probability of undergoing genetic testing by race and ethnicity.

RESULTS

Of 3551 study participants, 37.8% reported having heard of genetic testing for cancer risk and 3.9% stated that they underwent cancer genetic testing. Being non-Hispanic Black (OR=0.47, 95% CI=0.30-0.75) or Hispanic (OR=0.56, CI=0.35-0.90) was associated with lower odds of genetic testing knowledge. Although Hispanic or non-Hispanic Black respondents were more likely to perceive higher importance of genetic information versus non-Hispanic Whites, they had a lower predicted probability of cancer genetic testing.

CONCLUSION

Non-Hispanic Black and Hispanic adults had lower knowledge and were less likely to undergo cancer genetic testing than non-Hispanic Whites. Further research is needed on sources of genetic testing information for racial and ethnic minorities and the barriers to accessing genetic testing to inform the development of effective cancer risk genetic testing promotion.

Breast Cancer Disparity and Outcomes in Underserved Women

Women in the United States who continue to face obstacles accessing health care are frequently termed an underserved population. Safety-net health care systems play a crucial role in mitigating health disparities and reducing burdens of disease, such as breast cancer, for underserved women. Disparities in health care are driven by various factors, including race and ethnicity, as well as socioeconomic factors that affect education, employment, housing, insurance status, and access to health care. Underserved women are more likely to be uninsured or underinsured throughout their lifetimes. Hence they have greater difficulty gaining access to breast cancer screening and are less likely to undergo supplemental imaging when needed. Therefore, underserved women often experience significant delays in the diagnosis and treatment of breast cancer, leading to higher mortality rates. Addressing disparities requires a multifaceted approach, with formal care coordination to help at-risk women navigate through screening, diagnosis, and treatment. Mobile mammography units and community outreach programs can be leveraged to increase community access and engagement, as well as improve health literacy with educational initiatives. Radiology-community partnerships, comprised of imaging practices partnered with local businesses, faith-based organizations, homeless shelters, and public service departments, are essential to establish culturally competent breast imaging care, with the goal of equitable access to early diagnosis and contemporary treatment.

Pretest Video Education Versus Genetic Counseling for Patients With Prostate Cancer: ProGen, A Multisite Randomized Controlled Trial

PURPOSE

Germline genetic testing (GT) is recommended for men with prostate cancer (PC), but testing through traditional models is limited. The ProGen study examined a novel model aimed at providing access to GT while promoting education and informed consent.

METHODS

Men with potentially lethal PC (metastatic, localized with a Gleason score of ≥8, persistent prostate-specific antigen after local therapy), diagnosis age ≤55 years, previous malignancy, and family history suggestive of a pathogenic variant (PV) and/or at oncologist's discretion were randomly assigned 3:1 to video education (VE) or in-person genetic counseling (GC). Participants had 67 genes analyzed (Ambry), with results disclosed via telephone by a genetic counselor. Outcomes included GT consent, GT completion, PV prevalence, and survey measures of satisfaction, psychological impact, genetics knowledge, and family communication. Two-sided Fisher's exact tests were used for between-arm comparisons.

RESULTS

Over a 2-year period, 662 participants at three sites were randomly assigned and pretest VE (n = 498) or GC (n = 164) was completed by 604 participants (VE, 93.1%; GC, 88.8%), of whom 596 participants (VE, 98.9%; GC, 97.9%) consented to GT and 591 participants completed GT (VE, 99.3%; GC, 98.6%). These differences were not statistically significant although subtle differences in satisfaction and psychological impact were. Notably, 84 PVs were identified in 78 participants (13.2%), with BRCA1/2 PV comprising 32% of participants with a positive result (BRCA2 n = 21, BRCA1 n = 4).

CONCLUSION

Both VE and traditional GC yielded high GT uptake without significant differences in outcome measures of completion, GT uptake, genetics knowledge, and family communication. The increased demand for GT with limited genetics resources supports consideration of pretest VE for patients with PC.

Germline Genetic Testing Among Women ≤ 45 Years of Age with Ductal Carcinoma In Situ Versus Invasive Breast Cancer in a Large Integrated Health Care System

BACKGROUND

We compared the results of hereditary cancer multigene panel testing among patients ≤ 45 years of age diagnosed with ductal carcinoma in situ (DCIS) versus invasive breast cancer (IBC) in a large integrated health care system.

METHODS

A retrospective cohort study of hereditary cancer gene testing among women ≤ 45 years of age diagnosed with DCIS or IBC at Kaiser Permanente Northern California between September 2019 and August 2020 was performed. During the study period, institutional guidelines recommended the above population be referred to genetic counselors for pretesting counseling and testing.

RESULTS

A total of 61 DCIS and 485 IBC patients were identified. Genetic counselors met with 95% of both groups, and 86.4% of DCIS patients and 93.9% of IBC patients (p = 0.0339) underwent gene testing. Testing differed by race/ethnicity (p = 0.0372). Among those tested, 11.76% (n = 6) of DCIS patients and 16.71% (n = 72) of IBC patients had a pathogenic variant (PV) or likely pathogenic variant (LPV) based on the 36-gene panel (p = 0.3650). Similar trends were seen in 13 breast cancer (BC)-related genes (p = 0.0553). Family history of cancer was significantly associated with both BC-related and non-BC-related PVs in IBC, but not DCIS.

CONCLUSION

In our study, 95% of patients were seen by a genetic counselor when age was used as an eligibility criterion for referral. While larger studies are needed to further compare the prevalence of PVs/LPVs among DCIS and IBC patients, our data suggest that even in younger patients, the prevalence of PVs/LPVs in BC-related genes is lower in DCIS patients.

Communicating risk and the landscape of cancer prevention - an exploratory study that examines perceptions of cancer-related genetic counseling and testing among African Americans and Latinos in the Midwest

African American (AA) and Latino populations are impacted disproportionately by cancer incidence and mortality compared to the general US population. Contributing to these rates are multiple inheritable cancers that impact both men and women. Some of these diseases may be detected through genetic counseling and germline DNA testing; however, AA and Latinos are unaware and have limited knowledge and thus significantly underutilize these services and technologies. Research to detect influencing factors to testing uptake has also been slow due to multiple factors. The research team followed a community-based participatory research (CBPR) approach and worked with a Community Advisory Board composed of cancer survivors and co-survivors to design the exploratory study. Six focus groups were held with a pilot sample of African Americans and Latinos who self-reported to be at-risk for cancer (N = 53). The study was held over a 2-month period where attitudes, perceptions, and beliefs about cancer risk and preference regarding cancer-related genetic counseling and testing risk communication were explored. Themes that emerged included (1) the lack of knowledge about cancer-related genetic counseling and testing; (2) cancer is feared often; (3) cancer-related genetic testing was perceived as something that could help but was also perceived as unnecessary testing that exposed individuals to medical harm; and (4) benefits to test were perceived as favorable for medical personnel but not for the patient. Implications of the study provide a unique lens to explore how lived experiences among AA and Latinos may inform strategic risk communication about cancer-related genetic counseling and testing and help advance cancer health equity. Participants viewed cancer genetic testing as important cancer risk prevention strategies. Identification of perceptions of cancer risk and cancer-related genetic counseling and testing in collaboration with members of the community is needed to bolster communication efforts among these populations.

Latinx attitudes, barriers, and experiences with genetic counseling and testing: A systematic review

As genetics is increasingly used across clinical settings, there is a need to understand the impact and experiences of diverse patients. This review systematically examined research literature on Latinx experiences with genetic counseling and genetic testing (GC/GT) in the United States, synthesizing key themes and knowledge gaps pertaining to both patient experience and hypothetical scenarios. Findings were based on a systematic search, inclusion, and thematic analysis of 81 empirical peer-reviewed articles published from January 1990 to July 2019 pertaining to Latinx populations and GC/GT. Studies most commonly addressed Latinas' perspectives on GC/GT in prenatal settings or for hereditary breast and ovarian cancer (HBOC). Costs, referrals, and communication were significant barriers to accessing genetic services for many Latinx patients, particularly those with low English proficiency (LEP). Studies highlighted difficulties accessing and communicating in healthcare settings, and how medical context and prior experience with healthcare workers and institutions influenced GC/GT decision-making. Providers' implicit biases about Latinx patients negatively impacted their care and impeded communication. Despite low awareness of cancer GT, Latinx patients often reported interest in learning more about GC/GT or unmet needs for GT discussion and provider involvement. This systematic review identified areas where providers can take action to improve Latinx experiences with GC/GT. Clinicians should elicit and respond to patient preferences about shared decision-making. For patients with low numeracy or LEP, providers should consider tailored educational and communication techniques. Most studies focused on HBOC and prenatal testing, and Latinx patients are heterogeneous, leaving many research questions about Latinx experience with GT/GC in other clinical areas.

Awareness and use of genetic testing: An analysis of the Health Information National Trends Survey 2020

PURPOSE

Genetic testing is a tool used in a variety of settings for medical and nonhealth related purposes. The goal of this analysis was to better understand the awareness and use of genetic testing in the United States.

METHODS

Data from the 2020 Health Information National Trends Survey 5 cycle 4 were used to assess the awareness and use of genetic testing by demographic characteristics, personal cancer history, and family cancer history.

RESULTS

Overall, 75% of participants were aware of genetic testing and 19% of participants had genetic testing. Ancestry testing was the most common type of testing that the participants were aware of and had received. Non-Hispanic Asian, Non-Hispanic Black, and Hispanic respondents and participants with incomes less than $20,000 were less likely to be aware of and have received any type of genetic testing than the Non-Hispanic White participants and participants with higher income, respectively. Participants with a family history of cancer were more likely to be aware of cancer genetic testing than those without, and participants with a personal history of cancer were more likely to have had cancer genetic testing.

CONCLUSION

It appears awareness of genetic testing is increasing in the United States, and differences in awareness persist by race/ethnicity and income.

Testing a deliberative democracy method with citizens of African ancestry to weigh pros and cons of targeted screening for hereditary breast and ovarian cancer risk

Background

Democratic deliberation (DD), a strategy to foster co-learning among researchers and communities, could be applied to gain informed public input on health policies relating to genomic translation.

Purpose

We evaluated the quality of DD for gaining informed community perspectives regarding targeting communities of African Ancestry (AAn) for Hereditary Breast and Ovarian Cancer (HBOC) screening in Georgia.

Methods

We audiotaped a 2.5 day conference conducted via zoom in March 2021 to examine indicators of deliberation quality based on three principles: (1) inclusivity (diverse viewpoints based on participants' demographics, cancer history, and civic engagement), (2) consideration of factual information (balanced and unbiased expert testimonies, participant perceived helpfulness), and (3) deliberation (speaking opportunities, adoption of a societal perspective on the issue, reasoned justification of ideas, and participant satisfaction).

Results

We recruited 24 participants who reflected the diversity of views and life experiences of citizens of AAn living in Georgia. The expert testimony development process we undertook for creating balanced factual information was endorsed by experts' feedback. Deliberation process evaluation showed that while participation varied (average number of statements = 24, range: 3-62), all participants contributed. Participants were able to apply expert information and take a societal perspective to deliberate on the pros and cons of targeting individuals of AAn for HBOC screening in Georgia.

Conclusions

The rigorous process of public engagement using deliberative democracy approach can successfully engage a citizenry with diverse and well-informed views, do so in a relatively short time frame and yield perspectives based on high quality discussion.

Cancer screening and breast cancer family history in Spanish-speaking Hispanic/Latina women in California

Background

Breast cancer is the most common cancer among women in the U.S. and the leading cause of cancer death among Hispanics/Latinas (H/L). H/L are less likely than Non-H/L White (NHW) women to be diagnosed in the early stages of this disease. Approximately 5-10% of breast cancer can be attributed to inherited genetic mutations in high penetrance genes such as BRCA1/2. Women with pathogenic variants in these genes have a 40-80% lifetime risk of breast cancer. Past studies have shown that genetic counseling can help women and their families make informed decisions about genetic testing and early cancer detection or risk-reduction strategies. However, H/L are 3.9-4.8 times less likely to undergo genetic testing than NHW women. We developed a program to outreach and educate the H/L community about hereditary breast cancer, targeting monolingual Spanish-speaking individuals in California. Through this program, we have assessed cancer screening behavior and identified women who might benefit from genetic counseling in a population that is usually excluded from cancer research and care.

Materials and Methods

The "Tu Historia Cuenta" program is a promotores-based virtual outreach and education program including the cities of San Francisco, Sacramento, and Los Angeles. Participants responded to three surveys: a demographic survey, a breast cancer family history survey, and a feedback survey. Survey responses were described for participants and compared by area where the program took place using chi-square, Fisher exact tests, and t tests. Multinomial logistic regression models were used for multivariate analyses.

Results and Conclusion

We enrolled 1042 women, 892 completed the cancer family history survey and 62 (7%) provided responses compatible with referral to genetic counseling. We identified 272 women (42.8% ages 40 to 74 years) who were due for mammograms, 250 women (24.7% ages 25 to 65 years) due for Papanicolaou test, and 189 women (71.6% ages 50+) due for colorectal cancer screening. These results highlight the need of additional support for programs that spread awareness about cancer risk and facilitate access to resources, specifically within the H/L community.

Explaining Caste-Based Disparities in Enrollment for National Health Insurance Program in India: a Decomposition Analysis

BACKGROUND

Caste plays a significant role in individual healthcare access and health outcomes in India. Discrimination against low-caste communities contributes to their poverty and poor health outcomes. The Rashtriya Swasthya Bima Yojana (RSBY), a national health insurance program, was created to improve healthcare access for the poor. This study accounts for caste-based disparities in RSBY enrollment in India by decomposing the contributions of relevant factors.

METHODS

Using the data from the 2015-2016 round of the National Family Health Survey, we compare RSBY enrollment rates of low-caste and high-caste households. We use a non-linear extension of Oaxaca-Blinder decomposition and estimate two models by pooling coefficients across the comparison groups and all caste groups. Enrollment differentials are decomposed into individual- and household-level characteristics, media access, and state-level fixed effects, allowing 2000 replications and random ordering of variables.

RESULTS

The analysis of 480,766 households show that scheduled tribe households have the highest enrollment (18.85%), followed by 14.13% for scheduled caste, 10.67% for other backward caste, and 9.33% for high caste. Household factors, family head's characteristics, media access, and state-level fixed effects account for a 32% to 52% gap in enrollment. More specifically, the enrollment gaps are attributable to differences in wealth status, educational attainment, residence, family size, dependency ratio, media access, and occupational activities of the households.

CONCLUSIONS

Weaker socio-economic status of low-caste households explains their high RSBY enrollments.

Racial disparities in caesarean delivery among nulliparous women that delivered at term: cross-sectional decomposition analysis of Nebraska birth records from 2005-2014

BACKGROUND

Previous studies suggest higher rates of caesarean section among women who identify as racial/ethnic minorities. The objective of this study was to understand factors contributing to differences in caesarean rates across racial and ethnic groups.

METHODS

Data was collected from 2005 to 2014 Nebraska birth records on nulliparous, singleton births occurring on or after 37 weeks gestation (n = 87,908). Risk ratios (RR) and 95% confidence intervals (CI) for caesarean were calculated for different racial and ethnic categories, adjusting for maternal age, marital status, county of residence, education, insurance status, pre-pregnancy BMI, and smoking status. Fairlie decomposition technique was utilized to quantify the contribution of individual variables to the observed differences in caesarean.

RESULTS

In the adjusted analysis, relative to non-Hispanic (NH) White race, both Asian-NH (RR 1.21, 95% CI 1.14, 1.28) and Black-NH races (RR 1.13, 95% CI 1.08, 1.19) were associated with a significantly higher risk for caesarean. The decomposition analysis showed that among the variables assessed, maternal age, education, and pre-pregnancy BMI contributed the most to the observed differences in caesarean rates across racial/ethnic groups.

CONCLUSION

This analysis quantified the effect of social and demographic factors on racial differences in caesarean delivery, which may guide public health interventions aimed towards reducing racial disparities in caesarean rates. Interventions targeted towards modifying maternal characteristics, such as reducing pre-pregnancy BMI or increasing maternal education, may narrow the gap in caesarean rates across racial and ethnic groups. Future studies should determine the contribution of physician characteristics, hospital characteristics, and structural determinants of health towards racial disparities in caesarean rates.

Interest in Cancer Predisposition Testing and Carrier Screening Offered as Part of Routine Healthcare Among an Ethnically Diverse Sample of Young Women

Sequencing technologies can inform individuals’ risks for multiple conditions, supporting population-level screening approaches. Prior research examining interest in genetic testing has not generally examined the context of population-based approaches offered in routine healthcare or among ethnically diverse populations. Cancer predisposition testing and carrier screening could be offered broadly to women of reproductive age. This study therefore examined interest in these tests when offered as part of routine care, and predictors of interest, among an ethnically diverse sample of women aged 20–35. We conducted an online English-language survey of 450 women; 39% identified as Latina. We examined predictors of interest for two outcomes, interest in testing in the next year and level of interest, in multivariable logistic regression models and stratified analyses by Latina ethnicity. More than half of respondents reported being interested in cancer predisposition testing (55%) and carrier screening (56%) in the next year; this did not differ by ethnicity. About 26% reported being very interested in cancer predisposition testing and 27% in carrier screening. Latina respondents (32%) were more likely to be very interested in cancer predisposition testing than non-Latina respondents (22%; p < 0.03). In multivariable models, having higher worry about genetic risks, higher genetic knowledge, and higher perceived importance of genetic information were associated with higher interest across multiple models. Predictors of interest were generally similar by ethnicity. Our findings show substantial interest in both cancer predisposition testing and carrier screening among young women as part of routine healthcare with similar interest between Latina and non-Latina women. Efforts to broadly offer such testing could be important in improving access to genetic information. It will be critical to develop tools to help healthcare providers communicate about genetic testing and to address the needs of those who have less prior knowledge about genetics to support informed decision making.

The Role of Medical Mistrust in Concerns about Tumor Genomic Profiling among Black and African American Cancer Patients

Tumor genomic profiling (TGP) is used in oncology practice to optimize cancer treatment and improve survival rates. However, TGP is underutilized among Black and African American (AA) patients, creating potential disparities in cancer treatment outcomes. Cost, accuracy, and privacy are barriers to genetic testing, but medical mistrust (MM) may also influence how Black and AA cancer patients perceive TGP. From December 2019 to February 2020, 112 Black and AA adults from two outpatient oncology sites in Philadelphia, PA without a known history of having TGP testing conducted completed a cross-sectional survey. Items queried included sociodemographic characteristics, clinical factors, patient-oncologist relationship quality, medical mistrust, and concerns about TGP. A k-means cluster analysis revealed two distinct psychographic clusters: high (MM-H) versus low (MM-L) medical mistrust. Clusters were not associated with any sociodemographic or clinical factors, except for age (MM-H patients older than MM-L patients, p = 0.006). Eleven TGP concerns were assessed; MM-H patients expressed greater concerns than MM-L patients, including distrust of the government, insurance carriers, and pharmaceutical companies. TGP concerns varied significantly based on level of medical mistrust, irrespective of sociodemographic characteristics. Targeted communications addressing TGP concerns may mitigate disparities in TGP uptake among those with medical mistrust.

Decomposing Differences of Health Service Utilization among Chinese Rural Migrant Workers with New Cooperative Medical Scheme: A Comparative Study

The New Rural Cooperative Medical Insurance (NCMS) in China has provided benefits for rural migrant workers’ health service utilization, but the financial coordination and mutual aid of NCMS is mainly based on the county or district as a unit, leading NCMS with the characteristics of regional segmentation. Our study aims to explore their health service utilization, as well as to decompose differences of the health service utilization into contributors. Data from the China Labor-Force Dynamic Survey in 2016 and Urban Statistical Yearbook in 2016 were used. We used coarsened exact matching to control the confounding factors in order to enhance the comparison of two groups. The Fairlie decomposition method was used to analyze the differences and the sources of health service utilization. Influencing factors of health service utilization for rural migrant workers with NCMS were diversified, especially contextual characteristic and individual characteristics. The proportion of ethnic minorities, the number of medical institutions for 10,000 people in the community, the number of beds for 10,000 people in the city, and the urban service quality index were the major contributors of the differences. The proportion of difference in the health service utilization of rural migrant workers with NCMS caused by health service need were −54.73% and 6.92%, respectively. The inequities of the probability of two weeks outpatient, and the probability of inpatients, were −0.006 and −0.007, respectively. There were substantial differences in the health service utilization between rural migrant workers with NCMS in the county/district and rural migrant workers with NCMS across the county/district. Our results illustrated the inequity from the differences on basis of characteristic effect and the discrimination effect. Our studies clarified that health service needs of should be fully considered, contributing to a more reliable understanding of the health service utilization of rural migrant workers.

Racial and ethnic disparities in birth Outcomes: A decomposition analysis of contributing factors

This study seeks to quantify and rank the contribution of selected factors to the observed racial/ethnic disparities in low-birth-weight births (LBWBs) and preterm births (PTBs). Based on vital statistics data on births to primiparous women and characteristics of mothers in the State of Nebraska during the period of 2005 to 2014 (n = 93,375), unadjusted and adjusted odds ratios were estimated to examine the association between selected variables and the odds of having LBWBs or PTBs. Fairlie decomposition analysis was performed to quantify the contribution of each selected factor to racial/ethnic differences in LBWB and PTB rates. The prevalence of PTBs was 9.1% among non-Hispanic White (NHW) women, as compared to 12.8% among non-Hispanic Black (NHB) women and 10.6% among Hispanic women. The corresponding prevalence of LBWBs in the three groups were 5.9%, 11.9%, and 7.2%, respectively. The higher educational attainment among NHW women, relative to NHB women accounted for 10% of the observed difference in LBWB rate between the two groups. Health insurance coverage was the second most important factor accounting for the observed disparities in birth outcomes. Addressing socioeconomic disadvantages in NHB and Hispanic women would be important for them to narrow their gaps with NHW women in LBWB and PTB prevalence. More research is needed to identify key factors leading to the disparities in birth outcomes between NHW and NHB women.

Genetic counseling and testing for Asian Americans: a systematic review

PURPOSE

Asian Americans have been understudied in the literature on genetic and genomic services. The current study systematically identified, evaluated, and summarized findings from relevant qualitative and quantitative studies on genetic health care for Asian Americans.

METHODS

A search of five databases (1990 to 2018) returned 8,522 unique records. After removing duplicates, abstract/title screening, and full text review, 47 studies met inclusion criteria. Data from quantitative studies were converted into "qualitized data" and pooled together with thematic data from qualitative studies to produce a set of integrated findings.

RESULTS

Synthesis of results revealed that (1) Asian Americans are under-referred but have high uptake for genetic services, (2) linguistic/communication challenges were common and Asian Americans expected more directive genetic counseling, and (3) Asian Americans' family members were involved in testing decisions, but communication of results and risk information to family members was lower than other racial groups.

CONCLUSION

This study identified multiple barriers to genetic counseling, testing, and care for Asian Americans, as well as gaps in the research literature. By focusing on these barriers and filling these gaps, clinical genetic approaches can be tailored to meet the needs of diverse patient groups, particularly those of Asian descent.

Oncologists' Perceptions of Tumor Genomic Profiling and the Communication of Test Results and Risks

Tumor genomic profiling (TGP) identifies genetic targets for precision cancer treatments. The complexity of TGP can expose gaps in oncologists' skills, complicating test interpretation and patient communication. Research on oncologists' use and perceptions of TGP could inform practice patterns and training needs. To study this, a sample of oncologists was surveyed to assess TGP use, perceptions, and perceived skills in TGP interpretation/communication, especially in communication of hereditary risks. Genomic self-efficacy and TGP knowledge were also assessed. The goal sample (n = 50) was accrued from 12/2019 to 1/2020. Respondents were primarily medical oncologists (78%) with >10 (mean 17.7) years of practice experience. TGP use was moderate/high (median 50 [range 2-398]) tests/year. Most oncologists reported informal/no training in interpretation (72%) or communication (86%) of TGP results and risks. Genomic self-efficacy was high and was associated with higher use of TGP (p = 0.047). Perceptions of the benefits and limitations of TGP were mixed: heterogeneity was seen by years of experience, TGP use, and knowledge. Most participants agreed that additional training in TGP communication was needed, especially in communication of hereditary risks, and that an online training tool would be useful (86%). We conclude that oncologists are frequently using TGP despite having mixed views about its utility and not feeling prepared to communicate risks to patients. Oncologists receive little education in interpreting TGP or communicating its results and risks, and would value training in this area.

Impact of Age, Race, and Socioeconomic Status on Women's Perceptions and Preferences Regarding Communication of Estimated Breast Cancer Risk

RATIONALE AND OBJECTIVES

Performing breast cancer risk assessment at the time of screening mammography has potential to increase high-risk identification, appropriate supplemental screening, and risk management. The study's goal is to investigate women's interest in risk assessment and preferred method of risk communication in a diverse patient population.

MATERIALS AND METHODS

Surveys in English and five non-English languages were distributed to women presenting for screening mammography at eight screening mammography facilities between February and May 2019 to assess their interest in risk assessment, preferred method, and level of detail of estimated risk communication in hypothetical scenarios where estimated risks are average and elevated.

RESULTS

Among 683 survey respondents, 592 (87%) expressed interest in learning about their estimated lifetime risk of breast cancer. Controlling for age, race/ethnicity, and education, women with higher income were more interested in risk assessment than comparison group (p<0.05). The most preferred method of average risk communication was by a mailed letter accompanying mammographic results (57%), but more women exclusively preferred face-to-face communications of elevated risk than of average risk estimate (191, 28% vs. 128, 19%, p<0.0001). Phone communication was more preferred by younger women, electronic communication was less preferred by older women and those with lower income, and non-Hispanic blacks and older women preferred less detailed communication (p<0.05).

CONCLUSION

Sociodemographic factors influence women's interest in risk assessment and preference in risk communication about breast cancer. Screening Mammogram facilities implementing risk assessment should consider risk communication strategies that are most effective for their patient population.

Facilitated cascade testing (FaCT): a randomized controlled trial

BACKGROUND

Identifying mutation-carrying relatives of patients with hereditary cancer syndromes via cascade testing is an underused first step in primary cancer prevention. A feasibility study of facilitated genetic testing of at-risk relatives of patients with a known pathogenic mutation demonstrated encouraging uptake of cascade testing.

PRIMARY OBJECTIVE

Our primary objective is to compare the proportion of genetic testing of identified first-degree relatives of probands with a confirmed BRCA1/2 mutation randomized to a facilitated cascade testing strategy versus standard of care, proband-mediated, information sharing.

STUDY HYPOTHESIS

We hypothesize that facilitated cascade testing will drive significantly higher uptake of genetic testing than the standard of care.

TRIAL DESIGN

The FaCT (Facilitated Cascade Testing) trial is a prospective multi-institutional randomized study comparing the efficacy of a multicomponent facilitated cascade testing intervention with the standard of care. Patients with a known BRCA1/2 mutation (probands) cared for at participating sites will be randomized. Probands randomized to the standard of care group will be instructed to share a family letter with their first-degree relatives and encourage them to complete genetic testing. First-degree relatives of probands randomized to the intervention arm will receive engagement strategies with a patient navigator, an educational video, and accessible genetic testing services.

MAJOR INCLUSION/EXCLUSION CRITERIA

Adult participants who are first-degree relatives of a patient with a BRCA1/2 mutation and have not had prior genetic testing will be included.

PRIMARY ENDPOINT

Analyses will assess the proportion of first-degree relatives identified by the proband who complete genetic testing by 6 months in the intervention arm versus the control arm.

SAMPLE SIZE

One hundred and fifty probands with a BRCA1/2 mutation will be randomized. Each proband is expected to provide an average of 3 relatives, for an expected 450 participants.

ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS

January 2024.

Examining the uptake of predictive BRCA testing in the UK; findings and implications

Predictive BRCA testing is offered to asymptomatic individuals to predict future risk where a variant has been identified in a relative. It is uncertain whether all eligible relatives access testing, and whether this is related to health care inequalities. Our aim was to analyse trends and inequalities in uptake of testing, and identify predictors of testing and time-to-receipt of testing. A database from April 2010 to March 2017 was collated. Multivariate analysis explored individual associations with testing. Predictor variables included gender, BRCA test type, cancer history, Index of Multiple Deprivation (IMD) and education status. To evaluate factors associated with time-to-testing, a Cox proportional-hazards (CP) model was used. Of 779 tests undertaken, 336 (43.1%) were identified with a BRCA variant. A total of 537 (68.9%) were female and in 83.4% (387/464) of probands, predictive testing was received by relatives. Analysis identified inequalities since decreased testing was found when the proband was unaffected by cancer (OR 0.14, 95% CI 0.06-0.33). Median time-to-testing was 390 days (range, 0-7090 days) and the CP model also identified inequalities in the hazard ratio (HR) for testing for people aged >40 was higher than for aged <40 (HR 1.41, 95% CI 1.20-1.67) and BRCA2 testing was higher than for BRCA1 testing (HR 1.39, 95% CI 1.18-1.64). Reduced testing was found when probands were unaffected by cancer and time-to-testing was found to vary by age and BRCA1/2 test. Given limited study sample size, further research is recommended to examine inequalities in predictive BRCA testing.

Genetic testing and surgical treatment after breast cancer diagnosis: Results from a national online cohort

BACKGROUND

Genetic testing for hereditary breast cancer has implications for breast cancer decision-making. We examined genetic testing rates, factors associated with testing, and the relationship between genetic testing and contralateral prophylactic mastectomy (CPM).

METHODS

Patients with breast cancer (2000-2015) from The Health of Women Study were identified and categorized as low, moderate, or high-likelihood of the genetic mutation using a previously published scale based on period-relevant national guidelines incorporating age and family history. Genetic testing and CPM rates were compared using univariate and multivariate logistic regression.

RESULTS

Among 4170 patients (median age 56-years), 38% were categorized as high-likelihood of having a genetic mutation. Among high-likelihood women, 67% underwent genetic testing, the odds of which were increased among women of higher-education and White-race (p < .001). Among 2028 patients reporting surgical treatment, 385 (19%) chose CPM. CPM rate was highest among mutation-positive women (41%), but 26% of women with negative tests still underwent CPM. Independent of test result, genetic testing increased the odds of CPM on multivariate analysis (adjusted-OR: 1.69; 95% CI: 1.29-2.22).

CONCLUSIONS

Genetic testing rates were higher among women at high-likelihood of mutation carriage, but one-third of these women were not tested. Racial disparities persisted, highlighting the need to improve testing in non-White populations. CPM rates were associated with mutation-carriage and genetic testing, but many women chose CPM despite negative testing, suggesting that well-educated women consider factors other than cancer mortality in selecting CPM.

Experiences of Latino Participants Receiving Neutral Genomic Screening Results: A Qualitative Study

PURPOSE

The aim of the study was to characterize experiences of Latino participants receiving genomic screening results.

METHODS

Participants were recruited at a federally qualified health center in the USA. In-person, semi-structured interviews were conducted in either Spanish or English by a bilingual, bicultural interviewer. Questions focused on motivations for pursuing genomic sequencing, concerns about receiving genomic screening results, and perceived benefits of receiving genomic information. Interviews were audio-recorded, transcribed, and translated.

RESULTS

Fifty individuals completed an interview; 39 were conducted in Spanish. Participants described mixed motivations for pursuing genomic screening. Participants viewed the benefits of genomic screening in relation to not only their personal health but to the health of their families and their communities. Participants tended to have few concerns about genomic screening. Those concerns related to potential loss of privacy, misuses of genomic information, and the possibility of receiving distressing results. Some participants had misunderstandings about the scope of the test and the potential implications of their results. Most felt it was better to know about a genetic predisposition to disease than to remain uninformed. Participants felt that genomic screening was worthwhile.

DISCUSSION

This is one of the first studies to examine the experiences of Latino individuals receiving genomic screening results. Our results suggest that many Latino patients in the US see value in genomic screening and have limited concerns about its potential to cause harm. These results inform ongoing efforts to increase the availability of genomic medicine to underrepresented populations and add to our understanding of sociocultural drivers in the adoption of precision medicine.

The influence of social determinants of health on the genetic diagnostic odyssey: who remains undiagnosed, why, and to what effect?

Although Mendelian genetic disorders are individually rare, they are collectively more common and contribute disproportionately to pediatric morbidity and mortality. Remarkable advances in the past decade have led to identification of the precise genetic variants responsible for many of these conditions. Confirming the molecular diagnosis through genetic testing allows for individualized treatment plans in addition to ending the diagnostic odyssey, which not only halts further unnecessary testing but may also result in immense psychological benefit, leading to improved quality of life. However, ensuring equitable application of these advances in genomic technology has been challenging. Though prior studies have revealed disparities in testing for genetic predisposition to cancer in adults, little is known about the prevalence and nature of disparities in diagnostic testing in the pediatric rare disease population. While it seems logical that those with impaired access to healthcare would be less likely to receive the genetic testing needed to end their odyssey, few studies have addressed this question directly and the potential impact on health outcomes. This review synthesizes the available evidence regarding disparities in pediatric genetic diagnosis, defining the need for further, prospective studies with the ultimate goal of delivering precision medicine to all who stand to benefit. IMPACT: Social determinants of health are known to contribute to inequality in outcomes, though the impact on pediatric rare disease patients is not fully understood. Diagnostic genetic testing is a powerful tool, though it may not be available to all in need. This article represents the first effort, to our knowledge, to evaluate the existing literature regarding disparities in genetic testing for pediatric rare disease diagnosis and identify gaps in care.

State of recent literature on communication about cancer genetic testing among Latinx populations

Cancer-related genetic testing (hereafter CGT) has transformed cancer prevention, treatment, and care. Researchers debate whether diffusion and use of genetic testing will reduce or widen cancer health disparities through effects on improving or worsening cancer-related mortality, morbidity, and outcomes that disproportionately affect racial and ethnic minority populations. Cancer disparities by race and ethnicity have been associated with social determinants of health and healthcare access and experience. However, little research has explored how communication about CGT may contribute to these disparities. As such, the goal of this study was to characterize the literature published between 2010 and 2017 on communication about CGT among Latinx populations through a secondary analysis of papers identified in a larger scoping review. We found thirteen (2.5%) of 513 papers in the parent scoping review had over 50% Latinx representation; only nine of these (69%) had fully Latinx comprised study cohorts. The majority of the 13 identified studies (n = 9) were conducted to assess knowledge and attitudes regarding CGT. Most studies included services or materials in both Spanish and English. Few studies assessed language preference or acculturation or compared outcomes across sub-ethnicities. We identified opportunities for researchers to explore differences in outcomes by language preference and acculturation, and between sub-ethnicities in future studies. Leveraging a greater understanding of the heterogeneity within the Latinx population will allow genetics researchers and providers to improve utilization of CGT and therein health outcomes to advance health equity.

Prevalence and Spectrum of Pathogenic Germline Variants in Japanese Patients With Early-Onset Colorectal, Breast, and Prostate Cancer

PUPOSE

We investigated the prevalence and spectrum of pathogenic germline variants in patients with early-onset colorectal cancer (CRC), breast cancer (BC), and prostate cancer (PCA) in the Japanese population. We also identified pathogenic variants in other cancer risk genes, giving consideration to future multigene testing panels for this population.

METHODS

We performed whole-genome sequencing for 1,037 Japanese individuals, including patients with early-onset CRC (n = 196), BC (n = 237), and PCA (n = 215) and controls (n = 389). We screened for pathogenic variants, including single nucleotide variants and copy number variants, among well-established first-tier cancer genes for each cancer type and examined an expended second-tier panel including cancer-predisposing genes from the Cancer Gene Census.

RESULTS

Proportions of patients with germline pathogenic variants differed by cancer subgroup, with the highest in BC (14.8%), followed by CRC (9.2%), and PCA (3.7%). In contrast, 2 of 389 control subjects (0.5%) carried a germline pathogenic variant. In comparison with controls, the proportion of patients with pathogenic variants in the second-tier panel was increased significantly for PCA (3.7% to 11.6%, P = 2.96 × 10^-4), but not for CRC or BC, after multitesting adjustment. In patients with PCA, DNA repair pathway genes in the extended panel often contained pathogenic variants (P = .011).

CONCLUSION

Our analyses support the clinical usefulness of established cancer gene panels in the Japanese population for 3 major cancer types. Additional genes, especially those involved in DNA repair, might be considered for developing multipanel testing in Japanese patients with early-onset PCA.

Predictors of genetic beliefs toward cancer risk perceptions among adults in the United States: Implications for prevention or early detection

The objective of this study is to assess predictors of genetic beliefs toward cancer risk perceptions among adults, aged 18 years and over, in the United States (US). Data were obtained from the National Cancer Institute's (NCI) Health Information National Trends Survey 2014 (HINTS) 4 Cycle 4. Bivariate and multivariable logistic regression analyses were conducted to assess factors associated with an individual's beliefs about genetic and cancer risk perceptions. The results showed that African Americans, Non-White Hispanics, Non-Hispanic Asians, individuals with a high school education or less, and annual household incomes less than $20,000 and do not believe that health behaviors play some role in determining whether a person will develop cancer was significantly less likely to report that genetics plays at least some role in whether a person will develop cancer. Findings of this study provide an opportunity for genetic counselors to address beliefs about genetics and cancer risk perceptions among minority populations and promote health equity.

Impacts of apolipoprotein E disclosure on healthy Asian older adults: a cohort study

BACKGROUND

The apolipoprotein E (APOE) genotype provides information about Alzheimer's disease risk, yet genotype disclosure is discouraged due to concerns about possible distress. This is the first study investigating the psychological and behavioral impacts that genetic susceptibility testing for Alzheimer's disease has in an Asian population.

METHODS

From March 2016 to November 2017, we ran a prospective cohort study at Duke-National University of Singapore Medical School. 280 healthy Chinese elderly filled in questionnaires that measured psychological symptoms and health behaviors, 1 week before and 6 weeks after APOE genotype disclosure. Responses from ε4-positive subjects (associated with greater Alzheimer's disease risk) were compared to responses from ε4-negative subjects.

RESULTS

ε4 presence was not significantly associated with anxiety (p = 0.09) or depression (p = 0.25). No associations were found for changes to diet (p = 0.36), dietary supplements consumption (p = 0.90), physical activity (p = 0.15), or cognitive activity (p = 0.18).

CONCLUSION

There is no evidence to suggest that disclosure of APOE to Asian populations was associated with any short-term adverse psychological or behavioral impacts.

Psychosocial and Cultural Determinants of Interest and Uptake of Skin Cancer Genetic Testing in Diverse Primary Care

BACKGROUND

Translational research in genomics has limited reach and requires efforts to broaden access and utility in diverse populations. Skin cancer is common and rates are rising, including among Hispanics. Germline variants in the melanocortin-1 receptor (MC1R) gene are common in the population and confer moderate risk for melanoma and basal cell cancers across skin types. Feedback about MC1R risk status may promote skin cancer risk awareness and risk reduction.

AIMS

We examined the level of interest in pursuing MC1R testing, and patterns of interest across skin cancer perceived threat and control attitudes, cultural beliefs (family influence on health, health system distrust, cancer fatalism, skin cancer misconceptions), and health literacy.

METHODS

We used a study website to inform primary care patients in Albuquerque, NM about the benefits and drawbacks of MC1R testing. Website logon, request of a saliva test kit, and return of the test kit (yes vs. no) were primary assessments of study interest and uptake.

RESULTS

Of 499 participants provided with a test offer, 33% requested and returned the test. Lower family influence on participants' health was an important factor both overall and within ethnicity subgroups, and may indicate that primary care patients interested in skin cancer genetic testing see themselves as proactive health seekers, independent from family encouragement. Lower self-efficacy for skin cancer prevention was also an important characteristic of those who tested.

CONCLUSION

As evidence for common genetic markers for skin cancer accumulates, these findings suggest characteristics of those most likely to pursue genetic testing for skin cancer risk.

Developing a culturally targeted video to enhance the use of genetic counseling in Latina women at increased risk for hereditary breast and ovarian cancer

Disparities for genetic cancer risk assessment (GCRA) for hereditary breast and ovarian cancer (HBOC) persist between Latina and non-Hispanic Whites. There are few tested culturally targeted interventions. We developed a culturally targeted video to enhance GCRA uptake in at-risk Latinas. Interviews with healthcare providers (n = 20) and at-risk Latinas (n = 20) were conducted as formative research to inform the development of the video. Findings from the formative research, health behavior conceptual models, and evidence-based risk communication strategies informed the messages for the script. Then, we conducted a focus group with at-risk Latinas (n = 7) to obtain feedback for final refinement of the script. The final video was piloted for acceptability and potential dissemination in a sample of Latino community health workers (CHWs) (n = 31). Providers and at-risk Latinas suggested using simple language and visual aids to facilitate comprehension. Participants in the focus group identified areas for further clarification (e.g., cost). The result was an 18-min video that illustrates "Rosa's" story. Rosa learns about HBOC risk factors and overcomes barriers to attend genetic counseling. CHWs reported high overall satisfaction with the video (M = 9.61, SD = .88, range 1-10). A culturally targeted video has the potential to reach underserved populations with low literacy and English proficiency.

Exploring Predictors of Genetic Counseling and Testing for Hereditary Breast and Ovarian Cancer: Findings from the 2015 U.S. National Health Interview Survey

Despite efforts to increase the availability of clinical genetic testing and counseling for Hereditary Breast and Ovarian (HBOC)-related cancers, these services remain underutilized in clinical settings. There have been few efforts to understand the public's use of cancer genetic services, particularly for HBOC-related cancers. This analysis is based on data from the 2015 National Health Interview Survey (NHIS), a U.S.-based nationwide probability sample, to better understand the public's use of HBOC-related clinical cancer genetic services. Bivariate analyses were used to compute percentages and examine the associations of familial cancer risk for three genetic services outcomes (ever had genetic counseling for cancer risk, ever discussed genetic testing for cancer risk with a provider, and ever had genetic testing for cancer risk). Multivariable logistic regression models were used to estimate the association of familial cancer risk and other demographic and health variables with genetic services. Most women (87.67%) in this study were at low risk based on self-reported family history of breast and ovarian cancer, 10.65% were at medium risk, and 1.68% were at high risk. Overall, very small numbers of individuals had ever had genetic counseling (2.78%), discussed genetic testing with their physician (4.55%) or had genetic testing (1.64%). Across all genetic services outcomes, individuals who were at higher familial risk were more likely to have had genetic counseling than those at lower risk (high risk: aOR = 5.869, 95% CI = 2.911-11.835; medium risk: aOR = 4.121, 95% CI = 2.934-5.789), discussed genetic testing (high risk: aOR = 5.133, 95% CI = 2.699-9.764; medium risk: aOR = 3.649, 95% CI = 2.696-4.938), and completed genetic testing (high risk: aOR = 8.531, 95% CI = 3.666-19.851; medium risk aOR = 3.057, 95% CI = 1.835-5.094). Those who perceived themselves as being more likely to develop cancer than the average woman were more likely to engage in genetic counseling (aOR = 1.916, 95% CI = 1.334-2.752), discuss genetic testing (aOR = 3.314, 95% CI = 2.463-4.459) or have had genetic testing (aOR = 1.947, 95% CI = 1.13-3.54). Personal cancer history was also a significant predictor of likelihood to have engaged in genetic services. Our findings highlight: (1) potential under-utilization of cancer genetic services among high risk populations in the U.S. and (2) differences in genetic services use based on individual's characteristics such as self-reported familial risk, personal history, and beliefs about risk of cancer. These results align with other studies which have noted that awareness and use of genetic services are low in the general population and likely not reaching individuals who could benefit most from screening for inherited cancers. Efforts to promote public awareness of familial cancer risk may lead to better uptake of cancer genetic services.

Combined Effects of Race and Socioeconomic Status on Cancer Beliefs, Cognitions, and Emotions

AIM

To determine whether socioeconomic status (SES; educational attainment and income) explains the racial gap in cancer beliefs, cognitions, and emotions in a national sample of American adults.

METHODS

For this cross-sectional study, data came from the Health Information National Trends Survey (HINTS) 2017, which included a nationally representative sample of American adults. The study enrolled 2277 adults who were either non-Hispanic Black (n = 409) or non-Hispanic White (n = 1868). Race, demographic factors (age and gender), SES (i.e., educational attainment and income), health access (insurance status, usual source of care), family history of cancer, fatalistic cancer beliefs, perceived risk of cancer, and cancer worries were measured. We ran structural equation models (SEMs) for data analysis.

RESULTS

Race and SES were associated with perceived risk of cancer, cancer worries, and fatalistic cancer beliefs, suggesting that non-Hispanic Blacks, low educational attainment and low income were associated with higher fatalistic cancer beliefs, lower perceived risk of cancer, and less cancer worries. Educational attainment and income only partially mediated the effects of race on cancer beliefs, emotions, and cognitions. Race was directly associated with fatalistic cancer beliefs, perceived risk of cancer, and cancer worries, net of SES.

CONCLUSIONS

Racial gap in SES is not the only reason behind racial gap in cancer beliefs, cognitions, and emotions. Racial gap in cancer related beliefs, emotions, and cognitions is the result of race and SES rather than race or SES. Elimination of racial gap in socioeconomic status will not be enough for elimination of racial disparities in cancer beliefs, cognitions, and emotions in the United States.

Genetic Testing Across Young Hispanic and Non-Hispanic White Breast Cancer Survivors: Facilitators, Barriers, and Awareness of the Genetic Information Nondiscrimination Act

AIMS

This study compared facilitators and barriers to genetic testing and determined awareness about the Genetic Information Nondiscrimination Act (GINA) across young Hispanic and non-Hispanic white (NHW) breast cancer (BC) survivors.

MATERIALS AND METHODS

Women diagnosed with BC of age ≤50 years in 2009-2012 were recruited through the Florida State Cancer Registry to complete a questionnaire.

RESULTS

There were 1182 participants of which 61% (174/285) of Hispanic patients, and 65% (580/897) of NHW patients had BC testing. Among untested participants, the most common barriers were lack of testing recommendation (44% Hispanics, 32% NHW; p = 0.02) and cost-related concerns (41% Hispanics, 40% NHW; p = 0.83). Among tested participants, the top facilitators were as follows: (1) "To benefit my family's future" (70% Hispanic, 68% NHW), (2) "My doctor recommended testing" (60% Hispanic, 54% NHW), and (3) "Minimal cost to me" (59% Hispanic, 72% NHW). Only 27% of tested and 15% of untested women were aware of GINA; misuse of test results was reported as a barrier for only 6.5%.

CONCLUSIONS

Rates of genetic testing recommendation are lower among Hispanics, but both groups reported additional barriers. Most are unaware of GINA, yet misuse is not a highly cited barrier. Findings suggest the need to educate providers on the importance of recommending testing to all who meet criteria; increase awareness of newer options for more affordable testing; and bolster facilitators that may increase testing uptake.

Black and Minority Ethnic women's decision-making for risk reduction strategies after BRCA testing: Use of context and knowledge

Within the field of breast cancer care, women concerned about their family history are offered genetic testing and subsequent treatment options based on several factors which include but are not limited to personal and family cancer disease histories and clinical guidelines. Discussions around decision-making in genetics in Black and Minority Ethnic (BME) groups are rarely documented in literature, and information regarding interactions with genetics services is usually discussed and linked to lack of scientific knowledge. As such, counselling sessions based only on scientific and medical information miss out the many reasons participants consider in making health decisions, information which can be used to encourage BME women to engage in cancer genetics services. 10 BME women with a mixed personal and family history of breast and ovarian cancer backgrounds, were interviewed in a study exploring issues of knowledge about familial breast cancer syndromes, to understand how they created and used familial knowledge for health decisions, with a particular focus on attitudes towards risk reducing strategies. Study results show that our participants are not unique in the ways they make decisions towards the use of cancer genetics and risk reduction strategies and as such, there are no specific ethnically defined pathways for decision-making. Our participants demonstrated mixed biomedical, social and individual cultural reasons for their decision-making towards risk reduction surgeries and treatment options which are similar to women from different ethnicities and are individual rather than group-specific. Narratives about suspicion of scientific utility of genetic knowledge, the perceived predictive value of mutations for future cancers or the origin of mutations and family disease patterns feature heavily in how participants evaluated genetic information and treatment decisions. The diversity of results shows that our participants are interested in engaging with genetic information but use multiple sources for evaluating the extent of involvement in genetic services and the place of genetic information and treatment options for themselves and their families. Genetic information is considered within various bio-social scenarios before decision-making for risk reduction is undertaken. BME women are shown to undertake evaluative processes which clinicians are encouraged to explore for better patient support. Continuing to focus on links between superficial and un-representative meanings of ethnicity, ethnic identity and attitudes and behaviours by only searching for differences between ethnic groups, are unhelpful in further understanding how women from those diverse backgrounds make decisions towards risk reduction interventions. Future research must find ways of investigating and understanding populations in ways that are not focussed solely on ethnic differences but on how meaning is created out of social circumstances and experiences.

Provider's Perceptions of Barriers and Facilitators for Latinas to Participate in Genetic Cancer Risk Assessment for Hereditary Breast and Ovarian Cancer

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.

Family health history and genetic services-the East Baltimore community stakeholder interview project

Discussion of family health history (FH) has the potential to be a communication tool within families and with health providers to stimulate health promotion related to many chronic conditions, including those with genetic implications for prevention, screening, diagnosis, treatment. Diverse communities with disparities in health outcomes may require different approaches to engage individuals and families in the evolving areas of genetic risk communication, assessment, and services. This work was a partnership of a local urban agency and academic genetics professionals to increase understanding of community concerns and preferences related to FH and genetic awareness. Thirty community stakeholders in the East Baltimore area participated in structured interviews conducted by community members. We identified key themes on family health history FH, risk assessment, and genetic services. Forty-three percent (18/27) of community stakeholders thought families in East Baltimore did not discuss family health history FH with doctors. Stakeholders recognized the benefits and challenges of potential actions based on genetic risk assessment and the multiple competing priorities of families. FH awareness with community engagement and genetics education were the major needs identified by the participants. Research undertaken in active collaboration with community partners can provide enhanced consumer perspectives on the importance of family health history and its potential connections to health promotion and prevention activities.

Cancer genetic counseling communication with low-income Chinese immigrants

As genetics and genomics become part of mainstream medicine, these advances have the potential to either reduce or exacerbate health disparities. Relatively, little research has explored the quality of genetic counseling communication experienced by limited English proficiency patients, especially Chinese Americans. We observed and audio recorded genetic counseling appointments (n = 40) of low-income, limited English-proficient Chinese patients (n = 25) and conducted post-visit interviews (n = 17) using stimulated recall to examine patient understanding of the communication. Standard techniques based in grounded theory, including iterative data review and multiple coders, were used to analyze observation fieldnotes and interview transcripts and to identify these themes: (1) strong beliefs in environmental causes of cancer and skepticism about genetic causes, (2) willingness to undergo genetic testing despite skepticism of hereditary cause of cancer, (3) misunderstanding of key information needed to make informed decisions about testing and screening/prevention options, (4) variable quality of medical interpretation, and (5) selective family communication about cancer and genetic counseling and testing. Together, these themes describe substantial gaps in communication and identify the need for genetic counseling techniques and skills that enable counselors to communicate more effectively across language, literacy, and culture. Understanding the mechanisms of inheritance and the implications of genetic test results can be challenging for anyone, and it is exceptionally daunting for those who have limited English proficiency and/or low literacy. For Chinese immigrant patients to reap the full benefits of genetic counseling and testing, effective communication is essential. Research on interventions to improve communication is needed to ensure that disparities do not widen as genomic medicine reaches a more diverse population.

Trends and Gaps in Awareness of Direct-to-Consumer Genetic Tests From 2007 to 2014

INTRODUCTION

Direct-to-consumer genetic tests for inherited disease risks have gained recent approvals from the Food and Drug Administration, and interest in these tests has continued to grow. Broad use of these tests coupled with planning and discussion with health providers regarding genetic risks and potential protective behavior changes have been proposed as preventive tools to reduce health disparities and improve equity in health outcomes. However, awareness of direct-to-consumer genetic testing has historically demonstrated differences by education, income, and race; these disparities could jeopardize potential benefits by limiting access and use.

METHODS

The national survey data from the Health Information National Trends Survey was analyzed to understand how overall awareness of direct-to-consumer genetic testing and disparities in awareness across sociodemographic groups have changed since 2007.

RESULTS

The findings showed persistent disparities, as well as a widening gap in awareness between Hispanics and non-Hispanic whites (OR₂₀₀₇ =1.52, OR₂₀₁₄ =0.58, p_change =0.0056), despite overall increases in awareness over time.

CONCLUSIONS

Given these findings, policies regulating direct-to-consumer genetic tests should prioritize equitable distribution of benefits by including provisions that counteract prevailing disparities in awareness.

Attitudes Towards Prenatal Genetic Counseling, Prenatal Genetic Testing, and Termination of Pregnancy among Southeast and East Asian Women in the United States

Recognizing the heterogeneity of the Asian population with regards to acculturation, education, health awareness, and cultural values is vital for tailoring culturally sensitive and appropriate care. Prior studies show that cultural values influence perceptions of genetics within Asian populations. The reputation of the family unit factors into decisions such as pregnancy termination and disclosure of family medical history, and the nondirective model of American genetic counseling may conflict with the historical Asian model of paternalistic health care. Previous studies also provide conflicting evidence regarding correlations between education, acculturation, age, and awareness and perceptions of genetic testing. The aims of this study were to describe attitudes towards prenatal genetics among Southeast and East Asian women living in the United States for varying amounts of time and to explore sociocultural factors influencing those attitudes. Twenty-three Asian women who were members of Asian cultural organizations in the United States were interviewed via telephone about their attitudes towards prenatal genetic counseling, prenatal genetic testing, and termination of pregnancy. Responses were transcribed and coded for common themes using a thematic analysis approach. Four major themes emerged. In general, participants: (1) had diverse expectations for genetic counselors; (2) tended to weigh risks and benefits with regards to genetic testing decisions; (3) had mixed views on termination for lethal and non-lethal genetic conditions; and (4) identified cultural factors which influenced testing and termination such as lack of available resources, societal shame and stigma, and family pressure. These findings may allow prenatal genetic counselors to gain a richer, more nuanced understanding of their Asian patients and to offer culturally tailored prenatal genetic counseling.

Racial minority group interest in direct-to-consumer genetic testing: findings from the PGen study

There is little information regarding direct-to-consumer (DTC) personal genetic testing (PGT) in non-White racial minorities. Using a web-based survey, we compared the pretest interests and attitudes toward DTC-PGT of racial minority and White DTC-PGT customers of 23andMe and Pathway Genomics using chi-square tests and multinomial regression. Data were available for 1487 participants (1389 White, 44 Black, and 54 Asian). Survey responses were similar across racial groups, although a greater proportion of Blacks compared to Whites reported being "very interested" in genetic information related to traits (91.9 vs. 70.8%, p = 0.009). A greater proportion of Asians compared to Whites reported that a "very important" consideration for pursuing DTC-PGT was limited information about their family health history (58.0 vs. 37.5%, p = 0.002). While a number of significant differences between groups were observed in unadjusted analyses, they did not remain significant after adjustment. This study provides a preliminary view of the interests for purchasing DTC-PGT among customers with racial minority backgrounds.

Racial disparities in BRCA testing and cancer risk management across a population-based sample of young breast cancer survivors

BACKGROUND

Breast cancer (BC) disparities may widen with genomic advances. The authors compared non-Hispanic white (NHW), black, and Hispanic BC survivors for 1) cancer risk-management practices among BRCA carriers and 2) provider discussion and receipt of genetic testing.

METHODS

A population-based sample of NHW, black, and Hispanic women who had been diagnosed with invasive BC at age 50 years or younger from 2009 to 2012 were recruited through the state cancer registry. Multiple logistic regression was used to compare cancer risk-management practices in BRCA carriers and associations of demographic and clinical variables with provider discussion and receipt of testing.

RESULTS

Of 1622 participants, 159 of 440 (36.1%) black women, 579 of 897 (64.5%) NHW women, 58 of 117 (49.6%) Spanish-speaking Hispanic women, and 116 of 168 (69%) English-speaking Hispanic women underwent BRCA testing, of whom 90 had a pathogenic BRCA mutation identified. Among BRCA carriers, the rates of risk-reducing mastectomy and risk-reducing salpingo-oophorectomy were significantly lower among black women compared with Hispanic and NHW women after controlling for clinical and demographic variables (P = .025 and P = .008, respectively). Compared with NHW women, discussion of genetic testing with a provider was 16 times less likely among black women (P < .0001) and nearly 2 times less likely among Spanish-speaking Hispanic women (P = .04) after controlling for clinical and sociodemographic factors.

CONCLUSIONS

The current results suggest that the rates of risk-reducing salpingo-oophorectomy are lower among black BRCA carriers compared with their Hispanic and NHW counterparts, which is concerning because benefits from genetic testing arise from cancer risk-management practice options. Furthermore, lower BRCA testing rates among blacks may partially be because of a lower likelihood of provider discussion. Future studies are needed to improve cancer risk identification and management practices across all populations to prevent the widening of disparities.

Racial disparities in BRCA testing and cancer risk management across a population-based sample of young breast cancer survivors

Awareness, knowledge, perceptions, and attitudes towards genetic testing for cancer risk among ethnic minority groups: a systematic review

BACKGROUND

Genetic testing for risk of hereditary cancer can help patients to make important decisions about prevention or early detection. US and UK studies show that people from ethnic minority groups are less likely to receive genetic testing. It is important to understand various groups' awareness of genetic testing and its acceptability to avoid further disparities in health care. This review aims to identify and detail awareness, knowledge, perceptions, and attitudes towards genetic counselling/testing for cancer risk prediction in ethnic minority groups.

METHODS

A search was carried out in PsycInfo, CINAHL, Embase and MEDLINE. Search terms referred to ethnicity, genetic testing/counselling, cancer, awareness, knowledge, attitudes, and perceptions. Quantitative and qualitative studies, written in English, and published between 2000 and 2015, were included.

RESULTS

Forty-one studies were selected for review: 39 from the US, and two from Australia. Results revealed low awareness and knowledge of genetic counselling/testing for cancer susceptibility amongst ethnic minority groups including African Americans, Asian Americans, and Hispanics. Attitudes towards genetic testing were generally positive; perceived benefits included positive implications for personal health and being able to inform family. However, negative attitudes were also evident, particularly the anticipated emotional impact of test results, and concerns about confidentiality, stigma, and discrimination. Chinese Australian groups were less studied, but of interest was a finding from qualitative research indicating that different views of who close family members are could impact on reported family history of cancer, which could in turn impact a risk assessment.

CONCLUSION

Interventions are needed to increase awareness and knowledge of genetic testing for cancer risk and to reduce the perceived stigma and taboo surrounding the topic of cancer in ethnic minority groups. More detailed research is needed in countries other than the US and across a broader spectrum of ethnic minority groups to develop effective culturally sensitive approaches for cancer prevention.
