Disparities in genetic services utilization in a random sample of young breast cancer survivors.

PURPOSE: Increasing use of genetic services (counseling/testing) among young breast cancer survivors (YBCS) can help decrease breast cancer incidence and mortality. The study examined use of genetic services between Black and White/Other YBCS, attitudes and knowledge of breast cancer risk factors, and reasons for disparities in using genetic services. METHODS: We used baseline data from a randomized control trial including a population-based, stratified random sample of 3000 potentially eligible YBCS, with oversampling of Black YBCS. RESULTS: Among 883 YBCS (353 Black, 530 White/Other) were significant disparities between the two racial groups. More White/Other YBCS had received genetic counseling and had genetic testing than Blacks. Although White/Other YBCS resided farther away from board-certified genetic counseling centers, they had fewer barriers to access these services. Black race, high out-of-pocket costs, older age, and more years since diagnosis were negatively associated with use of genetic services. Black YBCS had lower knowledge of breast cancer risk factors. Higher education and genetic counseling were associated with higher genetic knowledge. CONCLUSION: Racial inequalities of cost-related access to care and education create disparities in genetic services utilization. System-based interventions that reduce socioeconomic disparities and empower YBCS with genetic knowledge, as well as physician referrals, can increase access to genetic services.

Surveillance for cancer recurrence in long-term young breast cancer survivors randomly selected from a statewide cancer registry.

PURPOSE: This study examined clinical breast exam (CBE) and mammography surveillance in long-term young breast cancer survivors (YBCS) and identified barriers and facilitators to cancer surveillance practices. METHODS: Data collected with a self-administered survey from a statewide, randomly selected sample of YBCS diagnosed with invasive breast cancer or ductal carcinoma in situ younger than 45 years old, stratified by race (Black vs. White/Other). Multivariate logistic regression models identified predictors of annual CBEs and mammograms. RESULTS: Among 859 YBCS (n = 340 Black; n = 519 White/Other; mean age = 51.0 ± 5.9; diagnosed 11.0 ± 4.0 years ago), the majority (> 85%) reported an annual CBE and a mammogram. Black YBCS in the study were more likely to report lower rates of annual mammography and more barriers accessing care compared to White/Other YBCS. Having a routine source of care, confidence to use healthcare services, perceived expectations from family members and healthcare providers to engage in cancer surveillance, and motivation to comply with these expectations were significant predictors of having annual CBEs and annual mammograms. Cost-related lack of access to care was a significant barrier to annual mammograms. CONCLUSIONS: Routine source of post-treatment care facilitated breast cancer surveillance above national average rates. Persistent disparities regarding access to mammography surveillance were identified for Black YBCS, primarily due to lack of access to routine source of care and high out-of-pocket costs. IMPLICATIONS: Public health action targeting cancer surveillance in YBCS should ensure routine source of post-treatment care and address cost-related barriers.

Genetic Testing and Surveillance of Young Breast Cancer Survivors and Blood Relatives: A Cluster Randomized Trial.

We compared a tailored and a targeted intervention designed to increase genetic testing, clinical breast exam (CBE), and mammography in young breast cancer survivors (YBCS) (diagnosed <45 years old) and their blood relatives. A two-arm cluster randomized trial recruited a random sample of YBCS from the Michigan cancer registry and up to two of their blood relatives. Participants were stratified according to race and randomly assigned as family units to the tailored (n = 637) or the targeted (n = 595) intervention. Approximately 40% of participants were Black. Based on intention-to-treat analyses, YBCS in the tailored arm reported higher self-efficacy for genetic services (p = 0.0205) at 8-months follow-up. Genetic testing increased approximately 5% for YBCS in the tailored and the targeted arm (p ≤ 0.001; p < 0.001) and for Black and White/Other YBCS (p < 0.001; p < 0.001). CBEs and mammograms increased significantly in both arms, 5% for YBCS and 10% for relatives and were similar for Blacks and White/Others. YBCS and relatives needing less support from providers reported significantly higher self-efficacy and intention for genetic testing and surveillance. Black participants reported significantly higher satisfaction and acceptability. Effects of these two low-resource interventions were comparable to previous studies. Materials are suitable for Black women at risk for hereditary breast/ovarian cancer (HBOC).

Development of a Web-based Family Intervention for BRCA Carriers and Their Biological Relatives: Acceptability, Feasibility, and Usability Study.

BACKGROUND: Carriers of breast cancer gene (BRCA) mutations are asked to communicate genetic test results to their biological relatives to increase awareness of cancer risk and promote use of genetic services. This process is highly variable from family to family. Interventions that support communication of genetic test results, coping, and offer decision support in families harboring a pathogenic variant may contribute to effective management of hereditary cancer. OBJECTIVE: The aim of this paper was to describe the development of the Family Gene Toolkit, a Web-based intervention targeting BRCA carriers and untested blood relatives, designed to enhance coping, family communication, and decision making. METHODS: We present findings from focus groups regarding intervention acceptability and participant satisfaction and from a pre-post pilot study with random allocation to a wait-listed control group regarding intervention feasibility and usability. RESULTS: The Family Gene Toolkit was developed by a multidisciplinary team as a psycho-educational and skills-building intervention. It includes two live webinar sessions and a follow-up phone call guided by a certified genetic counselor and a master's prepared oncology nurse. Each live webinar includes two modules (total four modules) presenting information about BRCA mutations, a decision aid for genetic testing, and two skill-building modules for effective coping and family communication. Participants in focus groups (n=11) were highly satisfied with the intervention, reporting it to be useful and describing clearly the important issues. From the 12 dyads recruited in the pre-post pilot study (response rate 12/52, 23%), completion rate was 71% (10/14) for intervention and 40% (4/10) for wait-listed control groups. CONCLUSIONS: Acceptability and satisfaction with the Family Gene Toolkit is high. On the basis of the findings from usability and feasibility testing, modifications on timing, delivery mode, and recruitment methods have been implemented.

Use of Cancer Genetics Services in African-American Young Breast Cancer Survivors.

INTRODUCTION: African-American women have higher rates of early-onset breast cancer compared with their Caucasian counterparts; yet, when diagnosed with breast cancer at a young age, they underuse genetic counseling and testing to manage their risk of developing future cancers. METHODS: Self-reported baseline data were collected between September 2012 and January 2013 and analyzed in 2014 from a subpopulation of 340 African-American young breast cancer survivors (YBCSs) enrolled in an RCT. YBCSs were diagnosed with invasive breast cancer or ductal carcinoma in situ between ages 20 and 45 years and were randomly selected from a statewide cancer registry. Logistic regression examined predictors of using cancer genetics services. RESULTS: Overall, 28% of the sample reported having genetic counseling and 21% reported having genetic testing, which were significantly lower (p≤0.005) compared with white/other YBCSs participating in the parent study. In a multivariate analysis, income was positively associated with counseling (B=0.254, p≤0.01) and testing (B=0.297, p≤0.01), whereas higher education levels (B=-0.328, p≤0.05) and lack of access to healthcare services owing to cost (B=-1.10, p≤0.03) were negatively associated with genetic counseling. Lower income and lack of care because of high out-of-pocket costs were commonly reported barriers. CONCLUSIONS: Despite national recommendations for genetic evaluation among women with early-onset breast cancer, few African-American YBCSs reported undergoing genetic counseling and testing. Most reported that their healthcare provider did not recommend these services. Interventions addressing patient, provider, and structural healthcare system barriers to using genetic counseling and testing in this population are needed.
