Insight into how patients with prostate cancer interpret and communicate genetic test results: implications for families.

Patients with prostate cancer (PCA) are increasingly being offered germline genetic testing for precision therapy, precision management, and clinical trial options. Genetic test results also have implications for family members. How men with PCA perceive their genetic test results and decide whether to share recommendations with family members is not well studied. We interviewed 12 patients who had PCA and genetic testing and received a positive variant/likely positive variant (PV/LPV) (n = 7) or a variant of unknown significance (VUS) (n = 5) result. The semi-structured interview had five sections: genetic testing experience, impact, and interpretation of the test result, deciding whether to communicate test results to family members, impact of communication on family members, and suggestions for genetic counselors and other PCA patients. Interviews were transcribed verbatim and thematic analysis was completed using NVivo software v10. Receipt of PV/LPV or VUS genetic test results was not as emotional as receiving the diagnosis of PCA itself. Seven of the 12 participants chose to share their test results with all relevant family members, 4 chose to share with select family members, and one chose to not disclose to any family members. The majority of family members who were aware of participants' genetic results have not undergone cascade genetic testing or sought cancer screening. Participants with PCA and positive or VUS genetic test results typically share their results with at least immediate family members, but some communication barriers exist. Understanding the best way to provide actionable and relevant information about genetic testing to family members remains a challenge.
