Factors Influencing Discussion of Cancer Genetic Testing with Health-Care Providers in a Population-Based Survey

Primary and Secondary Prevention Interventions to Reduce Risk Factors Associated with Colorectal Cancer in High-Risk Groups: a Systematic Literature Review

In the USA, colorectal cancer (CRC) is the 2nd leading cause of cancer-related deaths. Certain groups in the USA are at an increased risk of developing CRC, including those with a genetic risk and family history. The purpose of this project was to synthesize primary and secondary prevention interventions for individuals who are at high risk of CRC due to family history or genetic predisposition. This study systematically reviewed articles from PubMed, Google Scholar, and EBSCO using specific search terms to find relevant articles. Sixteen articles were identified for full-text review, which were categorized as non-drug interventions (n = 7) and drug interventions (n = 9). Non-drug interventions focused primarily on increasing screening in those with a first-degree relative (FDR) with CRC or those with Lynch syndrome (LS). Interventions that increased CRC screening often had a tailored component and were otherwise varied in study designs and intervention type. Drug interventions focused on the use of NSAIDs on patients with familial adenomatous polyposis (FAP). Studies showed very little racial and ethnic diversity. Findings suggest that tailored interventions are particularly effective in increasing CRC screening, and greater diversity of sample is needed with respect to race and ethnicity.

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.
