Annual prostate cancer screening may be particularly important for Black men, new data suggest.

The data come from a review of 45,834 veterans (aged 55–69 years) who had been diagnosed with prostate cancer. About one third of these men self-identified as non-Hispanic Black, and the rest were White.

During the study period (2004–2017), 2465 men (5.4%) died of the disease.

The review found that annual prostate-specific antigen (PSA) screening significantly reduced the risk of dying from prostate cancer among Black men but not White men.

The study was published online on August 4 in JAMA Oncology.

“These results may be biologically plausible because a shorter screening interval may be valuable for detecting aggressive disease, which is more common in Black men,” say investigators, led by University of California, withdrawls celexa San Diego, radiation oncology resident Michael Sherer, MD.

“Given that Black men are younger at diagnosis and have worse prostate cancer survival compared with White men,” more intensive screening recommendations “may benefit Black patients,” they write.

The study “conclusions are reasonable,” said Christopher Wallis, MD, PhD, a urologic oncologist at Mount Sinai Hospital in Toronto, Canada, when asked for comment.

Annual screening may well have “a greater potential to benefit” Black men, he said. “While we would ideally see randomized data supporting this, those data are unlikely to ever be forthcoming. Thus, this study provides a strong rationale to support the recommendations from many guideline panels (including those from the American Urological Association) that Black men, in the context of shared-decision making, may benefit more from PSA based prostate cancer screening than the population at large,” he added.

Overall, the findings could help inform screening discussions with Black men, the investigators comments. In its most recent guidance, the US Preventive Services Task Force recommends shared decision-making regarding PSA screening for men aged 55–69 years.

Similar Screening Frequency

For their study, the team reviewed Veterans Health Administration data to assess PSA screening patterns ― which they categorized as no screening, less than annual screening, or annual screening ― in the 5 years leading up to diagnosis.

They then correlated screening behaviors with the subsequent risk of dying from prostate cancer.

Overall, the reduction in risk of prostate cancer–specific mortality (PCSM) associated with screening was similar among Black men (subdistribution hazard ratio [sHR], 0.56; P = .001) and White men (sHR, 0.58; P = .001).

However, on multivariable regression, annual screening, in comparison with some screening, was associated with a significant reduction in the risk of dying from prostate cancer only among Black men (sHR, 0.65; P = .02), not among White men (sHR, 0.91; P = .35).

The cumulative incidence of PCSM among Black men was 4.7% with annual screening but 7.3% with only some screening.

Among White men, the cumulative incidence of PCSM with annual screening was 5.9%, vs 6.9% with less than annual screening.

Screening frequency was similar between Black men and White men. Black men were younger on average (61.8 vs 63.1 years) and had slightly higher PSA levels at diagnosis but were not more likely to have regional or metastatic disease.

No funding was reported for this study. The investigators have disclosed no relevant financial relationshps. Wallis has received personal fees from Janssen Canada.
