"Hope at a better chance": perspectives on genetic counseling and testing among black individuals with prostate cancer.

Abstract

Black individuals have the highest prostate cancer (PCa) incidence and mortality rates of any racial or ethnic group. Racial disparities persist in the understanding and uptake of genetics services, while the perspectives of Black individuals with PCa regarding genetic counseling and germline genetic testing for inherited cancer risk (GC/GT) remains understudied. This qualitative study explored attitudes, facilitators, and barriers to awareness, interest, and uptake of GC/GT among Black individuals with PCa. Eight individuals who self-identified as African American and/or Black with a personal history of PCa participated in individual telephone interviews using a semi-structured interview guide. Interview transcripts were analyzed using both an inductive and deductive coding approach, constant comparison, and selective coding. Five major themes were identified: (1) uncertainty surrounding personal relevance of GC/GT, (2) family influence and impact of GC/GT, (3) healthcare providers and institutions as gatekeepers of GC/GT, (4) community identity, influence, and impact of GC/GT, and (5) systemic barriers to GC/GT exemplify larger structural constraints. A key finding was the influence of community, a collective identity among Black individuals and a desire to benefit the Black community, in motivating research participation and pursuit of GC/GT to lessen racial disparities in PCa. Individual, interpersonal, institutional, community, and structural factors are both barriers and facilitators to awareness, interest, and uptake of GC/GT. Multilevel interventions such as communicating personal, familial, and community implications of GC/GT, improving patient-provider relationships and genetics education, and addressing systemic barriers are necessary to increase efficacy, utility, and equity in GC/GT.
