This indicates that they may face an increased risk of prostate cancer than white men at lower PSA levels. The findings were published by Wiley in CANCER, a peer-reviewed journal of the American Cancer Society.
What the study reveals about Black men and prostate cancer
For the study, researchers used models to predict the likelihood of prostate cancer diagnosis from a first biopsy for 75,295 Black and 207,658 white male veterans receiving care from the U.S. Department of Veterans Affairs (VA). Prostate cancer was detected in the first prostate biopsy in 55% of Black men and in 43% of white men.
After taking various competing factors into account, Black Veterans were 50% more likely to receive a prostate cancer diagnosis based on their first prostate biopsy than white veterans.
Understanding PSA levels and risk
Also, Black men with a pre-biopsy PSA of 4.0 ng/mL had a 49% risk of prostate cancer detected during their biopsy, compared with a 39% risk for white men with the same PSA level. The investigators’ model indicated that Black Veterans with a PSA of 4.0 ng/mL had an equivalent risk of prostate cancer as white Veterans with a PSA of 13.4 ng/mL.
“These findings suggest that to reduce health disparities for Veterans in the prevention of prostate cancer, clinicians should consider an individual Veteran’s risk for prostate cancer including factors such as race and age.
Clinicians may consider earlier screening for populations at greater than average risk, which includes Black men,” said first author Kyung Min Lee, PhD. Min Lee hails from the VA Informatics and Computing Infrastructure (VINCI), located within the VA Salt Lake City Health Care System.
Why prostate screening with PSA should be individualized
The VA recommends that, for the average risk of men ages 55–69 years, any decision to initiate or continue prostate cancer screening with PSA should be individualized. Jane Kim, MD, MPH, Executive Director for Preventive Medicine at the VA explained:
“This includes consideration of age, family history, race/ethnicity, medical conditions, and patient values, as well as potential benefits versus harms.
Per the U.S. Preventive Services Task Force, before deciding whether to be screened, men should have an opportunity to discuss the benefits and harms of screening through shared decision making with their clinicians.”
Bottom line
Dr. Lee added that prospective studies are needed to evaluate the risks and benefits of lower PSA biopsy thresholds informed by patient race and genetic risk scores.
“The VA Office of Research & Development has recently initiated the ProGRESS clinical trial—The Prostate Cancer, Genetic Risk, and Equitable Screening Study—to evaluate these questions,” he said.
