Abstract
Introduction: Black individuals have a two-fold higher rate of prostate cancer death in the US compared with other groups. This is the largest racial inequity in US cancer-related deaths. Annual prostate-specific antigen (PSA) testing among Black individuals starting at age 45 years could reduce mortality by 30% compared with current screening practices. Few current practice guidelines make race-conscious screening recommendations due to a lack of trial data on screening in Black populations; only 0-3% of participants in practice-informing PSA screening trial cohorts were Black. An equity-informed approach is required to ensure that trial designs reflect the priorities and perspectives of Black individuals to ensure their participation in future research. Methods: We partnered with the Black and African-descent Collaborative for Prostate Cancer ACtion (BACPAC) to conduct a survey to identify community priorities in prostate cancer early detection research. Respondents were asked to rate the importance of 15 research topics, then select the three topics most critical for research. Members of the BACPAC Virtual Research Community (VRC), a nationally representative group of 2,016 Black prostate cancer survivors and community members, were invited to participate. Eligible members were Black prostate cancer survivors and family members/caregivers of Black prostate cancer survivors. Those who met the inclusion criteria were emailed a unique link to complete the online survey. Results: 1,557 eligible VRC members received a survey link, 1,224 surveys were completed (78.6% response rate). 60% of respondents were survivors, 38% were family members/caregivers, and 2% were both. More than 80% of respondents rated each of the 15 research topics as moderately to very important. Topic rankings revealed two overarching priority areas, representing 6 out of 15 topics included in the survey. These areas were 1) the use of reflex testing in the setting of elevated PSA to aid detection of clinically significant cancer and 2) establishing optimal timing for initiation or interval of PSA testing for prostate cancer screening. Regarding use of reflex testing, 97.7% of respondents prioritized blood (44.3%), urine (27.8%), or MRI (25.6%) reflex testing. Regarding timing of PSA testing, 51.5% of respondents prioritized customized screening schedules based on personal risk factors, with 24.9% selecting to improve rates of screening and 26.6% selecting to improve detection of clinically significant cancers, and 25% of respondents prioritized initiating screening at age 45 to improve early detection of prostate cancer. Conclusion: Our survey identified critical research topics that are of high importance to Black prostate cancer survivors and their families/caregivers. Our findings bridge a critical gap in prostate cancer early detection research, from which Black individuals have been historically excluded. Involving Black prostate cancer survivors in research design may help ensure that Black individuals are better represented in future clinical trials.
