摘要

Background

Hispanic/Latinx males and those who are non-English proficient are significantly less likely to receive germline genetic evaluation for prostate cancer. Undertesting can impact downstream outcomes, including reduced access to approved targeted therapies, barriers to precision medicine trials, and hereditary cancer assessment for patients and family members. The goal of our study was to explore the knowledge and perceptions of genetic testing among U.S. Hispanic males, with the ultimate goal to identify potentially actionable targets to increase guideline-concordant genetic evaluation.

Methods

We conducted a nationwide online survey including U.S. Hispanic males aged ≥ 40 in English and Spanish using the 9-item Knowledge of Hereditary Prostate Cancer Scale and adapted questions about desire for more information from the Behavioral Beliefs about BRCA Genetic Counseling scale.

Results

Among 807 participants, the mean score for genetic knowledge was 5.8 out of 9, with gaps in understanding of incomplete penetrance of genes and maternal genetic inheritance. Medical mistrust and lower health literacy were associated with significantly lower knowledge of prostate cancer genetics. Overall, attitudes toward genetic counseling were favorable, with the majority of participants endorsing that it would help with decision-making, is concordant with cultural beliefs, and that they were interested in more information. Concerns about genetic evaluation included cost and impact for insurance.

Conclusions

Despite generally favorable attitudes toward genetic evaluation among Hispanic males, there are important knowledge gaps, including the importance of both maternal and paternal family history, as well as logistical concerns. Addressing these gaps through culturally targeted outreach may help to promote equitable uptake of germline genetic evaluation.
