Introduction:Differences in public awareness and uptake of genetic testing among patients with inheritable cancers are not well understood. The purpose of this study is to examine self-reported rates of undergoing cancer-specific genetic testing in patients with breast/ovarian cancer vs prostate cancer from a nationally representative sample of U.S. patients. Secondary objectives include examining sources of genetic testing information and perceptions of genetic testing for both patient populations as well as the general public.Methods:Data from the National Cancer Institute's Health Information National Trends Survey 5, Cycle 4 were used to generate nationally representative estimates of adults living in the U.S. Our exposure of interest was patient reported cancer history categorized as having: (1) either breast or ovarian cancer, (2) prostate cancer, or (3) no history of cancer. χ2 testing was used to compare differences among categorical variables.Results:In a nationally representative sample of 231.7 million adults, 3.7 million adults reported a history of breast/ovarian cancer while 1.5 million patients reported a history of prostate cancer; 52.3% of patients with breast/ovarian cancer vs 1.0% with prostate cancer reported undergoing cancer-specific genetic testing (P =.001). Patients with prostate cancer were less aware of cancer-specific genetic testing than either individuals with breast/ovarian cancer or adults without a cancer history (19.7% vs 64.7% vs 35.8%, respectively; P =.003). Health care professionals were the most common source of genetic testing information for patients with breast/ovarian cancer whereas the Internet was the most common source for patients with prostate cancer.Conclusions:Our results suggest a lack of awareness and limited utilization of genetic testing among patients with prostate cancer relative to breast/ovarian cancer. Patients with prostate cancer cite the Internet and social media as sources of information, which may be an avenue for more optimal dissemination of evidence-based information. © 2022 by AMERICAN UROLOGICAL ASSOCIATION EDUCATION AND RESEARCH, INC. |
