Mental Illness and BRCA1/2 Genetic Testing Intention Among Multiethnic Women Undergoing Screening Mammography

Current State of Genomics in Nursing: A Scoping Review of Healthcare Provider Oriented (Clinical and Educational) Outcomes (2012-2022)

In the 20 years since the initial sequencing of the human genome, genomics has become increasingly relevant to nursing. We sought to chart the current state of genomics in nursing by conducting a systematic scoping review of the literature in four databases (2012-2022). The included articles were categorized according to the Cochrane Collaboration outcome domains/sub-domains, and thematic analysis was employed to identify key topical areas to summarize the state of the science. Of 8532 retrieved articles, we identified 232 eligible articles. The articles primarily reported descriptive studies from the United States and other high-income countries (191/232, 82%). More than half (126/232, 54.3%) aligned with the "healthcare provider oriented outcomes" outcome domain. Three times as many articles related to the "knowledge and understanding" sub-domain compared to the "consultation process" subdomain (96 vs. 30). Five key areas of focus were identified, including "nursing practice" (50/126, 40%), "genetic counseling and screening" (29/126, 23%), "specialist nursing" (21/126, 17%), "nurse preparatory education" (17/126, 13%), and "pharmacogenomics" (9/126, 7%). Only 42/126 (33%) articles reported interventional studies. To further integrate genomics into nursing, study findings indicate there is a need to move beyond descriptive work on knowledge and understanding to focus on interventional studies and implementation of genomics into nursing practice.

Stress, anxiety, and health-related quality of life in BRCA1/2-positive women with and without cancer: A comparison of four US female samples

•

Anxiety and stress were significantly worse in BRCA1/2-positive women compared to comparable US female samples.

•

All health-related quality of life domains were better in BRCA1/2-positive women except energy/vitality, which was lower.

•

Patient-provider training and mental health referrals are needed to lessen psychosocial consequences of genetic testing.

Introduction

Women with BRCA1/2 mutations have a 11–72% increased risk of breast/ovarian cancers throughout their lifetime. The current study examines psychosocial differences between the current sample of BRCA1/2-positive women with and without cancer histories and three comparable United States (US) female samples without BRCA1/2 mutations.

Methods

Sixty BRCA1/2-positive women (with and without cancer histories) were recruited through multiple private online support groups in the US. Participants completed an online survey outlining sociodemographic and genetic counseling information, and anxiety, stress, and health-related quality of life (HRQoL) outcomes. Outcomes were compared to three similar US female normative samples via independent samples t-test analyses.

Results

State and trait anxiety (p = 0.00) and stress (p = 0.001) were significantly worse in the current sample of BRCA1/2-positive women compared comparable US female samples. All HRQoL domains were significantly better in the current sample except energy/vitality, which was significantly lower (p = 0.02) in the current sample. Results were stratified by cancer and recurrence status.

Conclusions

This study provides insight into how a sample of BRCA1/2-positive women both with and without cancer fare post-genetic counseling as compared to three normative female populations. Results infer the need for additional education, patient-provider training, and mental health referrals to support this population in order to circumvent unintended consequences and to improve psychosocial health in those being tested for, and those who test positive for, BRCA1/2 genetic mutations.

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.

Knowledge and perceptions of BRCA1/2 genetic testing and needs of diverse women with a personal or family history of breast cancer in South Florida

The vast majority of (BRCA1/2) genetic testing has been conducted in White women, in particular Ashkenazi Jewish women, with limited information available for Black and Hispanic women. Understanding perspectives of those who are underserved is critical to developing interventions to support inclusive approaches to genetic testing. This qualitative study explored knowledge and perceptions of BRCA1/2 genetic testing among diverse women in South Florida. We also explored participants' information needs. Convenience sampling was used to recruit a diverse group of 15 women with a personal or family history of breast cancer. We conducted semi-structured interviews and used grounded theory method to analyze the data. Five themes were identified: (1) lacking awareness and knowledge of BRCA1/2 genetic testing and results among Black women, (2) perceiving BRCA1/2 genetic testing as beneficial to themselves and a way to be proactive about cancer risk, (3) perceiving BRCA1/2 genetic testing as beneficial to family members, (4) interactions with healthcare providers and the healthcare system that shape genetic testing experiences, and (5) information needs for reducing cancer risk and promoting health. Our findings suggest that diverse underserved women perceived genetic testing as beneficial to themselves and family members. Women needed more information about the BRCA genes and genetic testing, prevention strategies, and the latest breast cancer research. Healthcare providers, particularly nurse practitioners, need to engage diverse high-risk women in discussions about their cancer risk, address unmet information needs, and, in particular, educate Black women about the benefits of pursuing genetic testing.
