Exploring Prostate Cancer Incidence by Ethnicity: A UK Cohort Study

Prostate cancer, a common malignancy, affects millions worldwide. Detecting clinically significant cases early is crucial for effective treatment. A recent cohort study delves into the relationship between ethnicity and prostate cancer incidence following a prostate-specific antigen (PSA) test in the UK.

Background

Prostate cancer is a global health concern, with approximately 1.4 million cases and 375,304 deaths reported in 2020[^1^][1]. Understanding how ethnicity influences prostate cancer risk is essential for tailored screening and management strategies.

The Study

The researchers analyzed data from 730,515 men registered at general practices in England. Eligible participants were aged 40 and over, had recorded ethnicity, and underwent a PSA test between 2010 and 2017 without a prior cancer diagnosis. The study aimed to assess prostate cancer incidence following a raised PSA result across different ethnic groups.

Main Findings

A striking difference emerged in 1-year prostate cancer incidence:

  • Black men: 24.7% (95% CI 23.3%, 26.2%)
  • White men: 19.8% (19.4%, 20.2%)
  • Asian men: 13.4% (12.2%, 14.7%)

Notably, 25% of Black men with a raised PSA were diagnosed with prostate cancer within one year, compared to 20% of White men and 13% of Asian men[^1^][1].

Implications

While more prostate cancer cases were diagnosed in Black men with elevated PSA levels, rates of advanced prostate cancer were not higher in this group. Age-adjusted thresholds revealed that Black men were significantly more likely to be diagnosed compared to White or Asian men. Understanding these ethnic disparities can inform targeted screening efforts and improve outcomes.
