Current Approaches to Cancer Genetic Counseling Services for Spanish-Speaking Patients

Assessing interventions promoting the uptake of cancer-related genomic services within the Latino community: A scoping review using the RE-AIM framework

Cancer genomic services (CGS) can support genetic risk-stratified cancer prevention and treatment. Racial/ethnic minority groups are less likely to access and utilize CGS compared with non-Hispanic Whites. Little research has described characteristics of interventions targeted at CGS among Latinos. This scoping review aimed to (1) describe interventions promoting uptake of CGS among Latinos in the United States and Latin America, (2) describe intervention adaptations for Latino participants, and (3) summarize intervention implementation factors suggested by reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework. We conducted a search in English and Spanish of literature published between 2005 and 2022 across PubMed and Latin American and Caribbean Health Sciences Literature databases. Sixteen of 2344 papers met the inclusion criteria of the analysis. Efforts to promote CGS among Latino communities were limited in the US and lower in Latin America. This review highlights the need for in-depth exploration of acculturation-informed interventions and better reporting on implementation factors to enhance their scalability across diverse settings.

Challenges and opportunities for Lynch syndrome cascade testing in the United States

Lynch syndrome is an underdiagnosed genetic condition that increases lifetime colorectal, endometrial, and other cancer risk. Cascade testing in relatives is recommended to increase diagnoses and enable access to cancer prevention services, yet uptake is limited due to documented multi-level barriers. Individual barriers such as feelings of fear, guilt, and anxiety and limited knowledge about Lynch syndrome as well as interpersonal barriers including complex family dynamics and language barriers limit family communication about Lynch syndrome and prevent uptake of genetic screening for relatives. Organizational and environmental barriers including a shortage of genetics professionals, high costs, and fears of discrimination also reduce cascade testing. These multi-level barriers may disproportionately impact underserved populations in the United States, such as individuals with lower incomes, limited English-speaking proficiency, lower educational attainment, and inadequate access to health systems. Multi-level facilitators of cascade testing include interpersonal support from family members, peers, and healthcare providers, educational resources, and motivation to improve family health. Taken together, these barriers and facilitators demonstrate a need for interventions and strategies that address multi-level factors to increase cascade testing in families with Lynch syndrome and other hereditary cancer conditions. We provide an example of a cascade testing intervention that has been developed for use in individuals diagnosed with Lynch syndrome and discuss the variety of current approaches to addressing these multi-level barriers.

Piloting a Spanish-Language Web-Based Tool for Hereditary Cancer Genetic Testing

The delivery of hereditary cancer pre-test education among Spanish-language patients is impeded by the dearth of Spanish-speaking genetic counselors. To address this gap, we evaluated a web-based genetic education tool delivered in Spanish to provide information typically discussed during an initial genetic counseling session. Spanish-speaking patients with a personal or family history of cancer were recruited at two centers in Puerto Rico and through social media. A total of 41 participants completed a survey before and after viewing the tool to measure knowledge, attitudes, and decisional empowerment. A subset of 10 participants completed a virtual semi-structured interview to assess the usability and appropriateness of the tool. Paired t-tests were calculated to evaluate changes in knowledge and attitudes. A McNemar test assessed for decisional empowerment. Interview transcripts were translated from Spanish to English and inductively coded and analyzed. Results revealed significant increases in knowledge (p < 0.001), while attitudes about genetic testing did not change (p = 0.77). The proportion of individuals who felt fully informed and empowered to decide about whether to undergo genetic testing increased from 15% to 51% (p < 0.001). Qualitative data indicated that participants found the tool easy to use with informative and valuable content. Our findings suggest this Spanish-language tool is a user-friendly and scalable solution to help inform and empower many individuals to decide about cancer genetic testing, recognizing that others may still benefit from genetic counseling prior to testing.

Digital interventions for genomics and genetics education, empowerment, and service engagement: A systematic review

BACKGROUND

Patient-facing digital technologies may reduce barriers to and alleviate the burden on genetics services. However, no work has synthesised the evidence for patient-facing digital interventions for genomics/genetics education and empowerment, or to facilitate service engagement more broadly. It is also unclear which groups have been engaged by digital interventions.

AIM

This systematic review explores which existing patient-facing digital technologies have been used for genomics/genetics education and empowerment, or to facilitate service engagement, and for whom and for which purposes the interventions have been developed.

METHODS

The review adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Eight databases were searched for literature. Information was extracted into an Excel sheet and analysed in a narrative manner. Quality assessments were conducted using the Mixed Methods Appraisal Tool.

RESULTS

Twenty-four studies were included, of which 21 were moderate or high quality. The majority (88%) were conducted in the United States of America or within a clinical setting (79%). More than half (63%) of the interventions were web-based tools, and almost all focussed on educating users (92%). There were promising results regarding educating patients and their families and facilitating engagement with genetics services. Few of the studies focussed on empowering patients or were community-based.

CONCLUSION

Digital interventions may be used to deliver information about genetics concepts and conditions, and positively impact service engagement. However, there is insufficient evidence related to empowering patients and engaging underserved communities or consanguineous couples. Future work should focus on co-developing content with end users and incorporating interactive features.

Cultural adaptations to a telephone genetic counseling protocol and booklet for Latina breast cancer survivors at risk for hereditary breast and ovarian cancer

Telephone genetic counseling (TGC) is accepted as standard clinical care for people seeking hereditary cancer risk assessment. TGC has been shown to be non-inferior to in-person genetic counseling, but trials have been conducted with a predominantly highly educated, non-Hispanic White population. This article describes the process of culturally adapting a TGC protocol and visual aid booklet for Spanish-preferring Latina breast cancer survivors at risk for hereditary breast and ovarian cancers. The adaptation process included two phases. Phase 1 involved a review of the literature and recommendations from an expert team including community partners. Phase 2 included interviews and a pilot with the target population (n = 14) to collect feedback about the adapted protocol and booklet following steps from the Learner Verification and Revision Framework. We describe the adaptation process and report the main adaptations following the Framework for Reporting Adaptations and Modifications to Evidence-based Interventions (FRAME). Adaptations in Phase 1 were responsive to the target population needs and characteristics (e.g., delivered in Spanish at an appropriate health literacy level, addressing knowledge gaps, targeting cultural values). Phase 2 interviews were crucial to refine details (e.g., selecting words) and to add components to address GCT barriers (e.g., saliva sample video). Cultural adaptations to evidence-based TGC protocols can increase the fit and quality of care for historically underserved populations. As TGC visits become routine in clinical care, it is crucial to consider the needs of diverse communities to adequately promote equity and justice in cancer care.

Behavioral beliefs about genetic counseling among high-risk Latina breast cancer survivors in Florida and Puerto Rico

Compared with non-Hispanic White women, Latina women are less likely to receive genetic counseling (GC) and testing (GT) following BC diagnosis. This study used secondary data analysis to explore beliefs about GC among Latina BC survivors in and outside the US mainland. GC/GT-naïve, high-risk, Spanish-preferring Latina BC survivors (n = 52) in FL and PR completed the Behavioral Beliefs about GC scale. Participants reported high positive beliefs about GC (M = 4.19, SD = 0.92); the majority agreed that GC was beneficial to understand cancer risk (90%) and promote discussion (87%) in their family. Participants reported low-to-moderate scores for barriers (Ms = 1.53-3.40; SDs = 0.59-0.90). The most frequently endorsed barriers were desire for additional GC information (M = 3.44; SD = 0.90), and GC logistic concerns (M = 2.71; SD = 0.80). No statistically significant differences for barriers and benefits scales were identified by place of residence (all ps ≥ 0.12). These findings highlight the importance of delivering culturally sensitive GC information to high-risk Latina BC survivors.

Delivering Genetic Testing for Patients with Prostate Cancer: Moving Beyond Provider Knowledge as a Barrier to Care

INTRODUCTION

The 2018 National Comprehensive Cancer Network guidelines for prostate cancer genetic testing expanded access to genetic services. Few studies have examined how this change has affected provider practice outside of large cancer centers.

METHODS

We conducted a qualitative study of multi-disciplinary health care providers treating patients with prostate cancer at a safety-net hospital. Participants completed an interview that addressed knowledge, practices, and contextual factors related to providing genetic services to patients with prostate cancer. A thematic analysis using both inductive and deductive coding was undertaken.

RESULTS

Seventeen providers completed interviews. Challenges in identifying eligible patients for genetic testing stemmed from a lack of a) systems that facilitate routine patient identification, and b) readily available family history data for eligibility determination. Providers identified non-medical patient characteristics that influenced their referral process, including health literacy, language, cultural beliefs, patient distress, and cost. Providers who see patients at different times along the cancer care continuum viewed benefits of testing differently.

CONCLUSION

The use of digital technologies that systematically identify those eligible for genetic testing referrals may mitigate some but not all challenges identified in this study. Further research should determine how individual provider perceptions influence referral practices and patient access to genetics both within and across cancer specialties.

Measuring quality and value in genetic counseling: The current landscape and future directions

Genetic counselors strive to provide high-quality genetic services. To do so, it is essential to define quality in genetic counseling and identify opportunities for improvement. This Professional Issues article provides an overview of the evaluation of healthcare quality in genetic counseling. The National Society of Genetic Counselors' Research, Quality, and Outcomes Committee partnered with Discern Health, a value-based healthcare policy consulting firm, to develop a care continuum model of genetic counseling. Using the proposed model, currently available quality measures relevant to genetic counseling in the US healthcare system were assessed, allowing for the identification of gaps and priority areas for further development. A total of 560 quality measures were identified that can be applied to various aspects of the care continuum model across a range of clinical specialty areas in genetic counseling, although few measures were specific to genetic counseling or genetic conditions. Areas where quality measures were lacking included: attitudes toward genetic testing, family communication, stigma, and issues of justice, equity, diversity, and inclusion. We discuss these findings and other strategies for an evidence-based approach to quality in genetic counseling. Strategic directions for the genetic counseling profession should include a consolidated approach to research on quality and value of genetic counseling, development of quality metrics and patient-experience measures, and engagement with other improvement activities. These strategies will allow for benchmarking, performance improvement, and future implementation in accountability programs which will strengthen genetic counseling as a profession that provides evidence-based high-quality care to all patients.

Provider discussion of genetic counseling among high-risk Spanish-preferring Latina breast cancer survivors

Among high-risk breast cancer (BC) survivors, genetic counseling (GC) and genetic testing (GT) may inform cascade testing and risk management. Compared to non-Hispanic White BC survivors, Spanish-preferring Latina BC survivors are less likely to report discussing GC with a healthcare provider. However, few studies have examined Latinas' experiences with GC/GT, particularly outside of the mainland USA. This study aimed to compare frequency of provider discussion of GC between Spanish-preferring Latina BC survivors living in Florida (FL) and Puerto Rico (PR). We conducted secondary data analysis of baseline assessments from a randomized pilot of an educational intervention for Spanish-preferring Latina BC survivors. Participants (N = 52) were GC/GT-naive, but met clinical criteria for GC/GT referral. Participants self-reported sociodemographic, clinical, and cultural variables, including previous provider discussion of GC. Descriptive statistics characterized frequency of GC discussion. Logistic regression examined the relationships between sociodemographic, clinical, and cultural characteristics and GC discussion. Only 31% of participants reported previous GC discussion. More participants from PR reported having GC discussions (43% vs. 21% in the mainland USA). In multivariable analyses, greater likelihood of GC discussion was associated with PR (vs. mainland USA) residence (odds ratio [OR] = 6.00, p = .03), older age at baseline (OR = 1.19, p = .04), and younger age at BC diagnosis (OR = 0.80, p = .03). Few high-risk Spanish-preferring Latina BC survivors in the mainland USA and PR had discussed GC with their providers. These results highlight a gap in the implementation of evidence-based genetics guidelines. Provider-directed interventions may be needed to increase uptake of GC/GT among Latina BC survivors.

Anxiety and depression among racial/ethnic minorities and impoverished women testing positive for BRCA1/2 mutations in the United States

PURPOSE

To outline the association between race/ethnicity and poverty status and perceived anxiety and depressive symptomologies among BRCA1/2-positive United States (US) women to identify high-risk groups of mutation carriers from medically underserved backgrounds.

METHODS

A total of 211 BRCA1/2-positive women from medically underserved backgrounds were recruited through national Facebook support groups and completed an online survey. Adjusted odds ratios (aOR) and 95% confidence intervals (CIs) were estimated using multivariable logistic regression for associations between race/ethnicity, poverty status, and self-reported moderate-to-severe anxiety and depressive symptoms.

RESULTS

Women ranged in age (18-75, M = 39.5, SD = 10.6). Most women were non-Hispanic white (NHW) (67.2%) and were not impoverished (76.7%). Hispanic women with BRCA1/2 mutations were 6.11 times more likely to report moderate-to-severe anxiety (95% CI, 2.16-17.2, p = 0.001) and 4.28 times more likely to report moderate-to-severe depressive symptoms (95% CI, 1.98-9.60, p < 0.001) than NHW women with these mutations. Associations were not statistically significant among other minority women. Women living in poverty were significantly less likely to report moderate-to-severe depressive symptoms than women not in poverty (aOR, 0.42, 95% CI, 0.18-0.95, p = 0.04).

CONCLUSION

Hispanic women with BRCA1/2 mutations from medically underserved backgrounds are an important population at increased risk for worse anxiety and depressive symptomology. Our findings among Hispanic women with BRCA1/2 mutations add to the growing body of literature focused on ethnic disparities experienced across the cancer control continuum.

A pilot randomized trial of an educational intervention to increase genetic counseling and genetic testing among Latina breast cancer survivors

Latinas are less likely to participate in genetic counseling (GC) and genetic testing (GT) than non-Hispanic Whites. A multisite, randomized pilot study tested a culturally targeted educational intervention to increase uptake of GC/GT among Latina breast cancer (BC) survivors (N = 52). Participants were recruited in Tampa, FL and Ponce, PR and randomized to: (a) fact sheet about BC survivorship (control) or (b) a culturally targeted educational booklet about GC/GT (intervention). Participants in the intervention condition were also offered no-cost telephone GC followed by free GT with mail-based saliva sample collection. Participants self-reported hereditary breast and ovarian cancer (HBOC) knowledge and emotional distress at baseline and 1- and 3-month follow-ups. We used logistic regression to examine differences in GC/GT uptake by study arm (primary outcome) and repeated measures ANOVA to examine the effects of study arm and time on HBOC knowledge and emotional distress (secondary outcomes). Compared to the control arm, intervention participants were more likely to complete GC (ORIntervention  = 13.92, 95% CI = 3.06-63.25, p < .01) and GT (ORIntervention  = 12.93, 95% CI = 2.82-59.20, p < .01). Study site did not predict uptake of GC (p = .08) but Ponce participants were more likely to complete GT (ORPonce  = 4.53, 95% CI = 1.04-19.72, p = .04). ANOVAs demonstrated an increase in HBOC knowledge over time across both groups (F(2,88) = 12.24, p < .01, ηp2  = 0.22). We also found a significant interaction of study arm and time, such that intervention participants demonstrated a greater and sustained (to the 3-month follow-up) increase in knowledge than control participants (F(2,88) = 3.66, p = .03, ηp2  = 0.08). No other main or interaction effects were significant (all p's> .15). Study findings demonstrate the potential of our culturally targeted print intervention. Lessons learned from this multisite pilot study for enhancing GC/GT in Latinas include the need to attend to both access to GC/GT and individual factors such as attitudes and knowledge.

Culturally Targeted Video Improves Psychosocial Outcomes in Latina Women at Risk of Hereditary Breast and Ovarian Cancer

Latina women at risk of hereditary breast and ovarian cancer (HBOC) have lower awareness, knowledge, and use of genetic counseling and testing services (GCT) than non-Latina Whites. Few interventions have been developed to reduce these disparities among at-risk Latinas. This pilot study assessed the impact of a culturally targeted narrative video developed by our team. The study included 40 Latina immigrants living in the United States who were at risk of HBOC, including affected and unaffected women. We assessed pre-post differences in psychosocial outcomes. Participants were 47.35 years old on average (SD = 9.48). Most (70%) were unaffected with cancer, had an annual income of $40,000 or less (65%), an education of High School or less (62.5%), and were uninsured (77.5%). The video significantly enhanced knowledge (p < 0.001), positive attitudes (p < 0.05), anticipatory positive emotions (p < 0.05), and intentions to participate in counseling (p < 0.001). Importantly, the video also significantly reduced negative attitudes (p < 0.05), and attitudinal ambivalence (p < 0.001). The culturally targeted video shows preliminary evidence in improving psychosocial outcomes related to GCT uptake in Latinas at risk for HBOC. This intervention is a promising easily-disseminable strategy to address disparities in GCT utilization.

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.

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.
