Table 16. Summary of Cross-Sectional Studies of Anticipated Interest in Prostate Cancer Susceptibility Genetic Testing

Study Population Sample Size Percent Expressing Interest in Genetic Testing Other Findings 
FDR = first-degree relative; PSA = prostate-specific antigen
Prostate screening clinic participants [17]342 men aged 40–97 y89%28% did not demonstrate an understanding of the concept of inherited predisposition to cancer.
General population; 9% with positive family history [8]12 focus groups with a total of 90 men aged 18–70 yAll focus groups
African American men [18]320 men aged 21–98 y87%Most participants could not distinguish between genetic susceptibility testing and a prostate-specific antigen blood test.
Men with and without FDRs with prostate cancer [9]126 men aged >40 y; mean age 52.6 y24% definitely; 50% probably
Swedish men with an FDR with prostate cancer [3]110 men aged 40–72 y76% definitely; 18% probably89% definitely or probably wanted their sons to undergo genetic testing.
Sons of Swedish men with prostate cancer [10]101 men aged 21–65 y90%; 100% of sons with two or three family members affected with prostate cancer60% expressed worry about having an increased risk of prostate cancer.
Healthy outpatient males with no history of prostate cancer [19]400 men aged 40–69 y82%
Healthy African American males with no history of prostate cancer [20]413 African American men aged 40–70 y87%Belief in the efficacy of and intention to undergo prostate cancer screening was associated with testing interest.
Healthy Australian males with no history of prostate cancer [21]473 adult men66% definitely; 26% probably73% reported that they felt diet could influence prostate cancer risk.
Males with prostate cancer and their unaffected male family members [22]559 men with prostate cancer; 370 unaffected male relatives45% of men affected with cancer; 56% of unaffected menIn affected men, younger age and test familiarity were predictors of genetic testing interest. In unaffected men, older age, test familiarity, and a PSA test within the last 5 y were predictors of genetic testing interest.
