Community prostate-specific antigen (PSA) screening attracts middle-aged white men. Elevated PSA levels and prostate cancer diagnoses increase with age, highlighting the need for age-specific PSA reference ranges.

Area of Science:

  • Urology
  • Public Health
  • Epidemiology

Background:

  • Community-based prostate-specific antigen (PSA) screening programs aim to detect prostate cancer early.
  • Understanding participant demographics and expected serum PSA levels is crucial for program effectiveness.

Purpose of the Study:

  • To identify characteristics of men participating in PSA screening.
  • To determine expected serum PSA levels in a screened population.

Main Methods:

  • Descriptive analysis of 5548 men in an annual community health screening program.
  • Comparison of participants who chose PSA screening versus those who did not.
  • Multivariate regression analysis to evaluate demographic variables' relationship to PSA levels.

Main Results:

  • PSA screening participants were disproportionately middle-aged, white men with higher incomes.
  • Non-participants were more likely to be very young or very old.
  • PSA levels and elevated PSA percentages increased with age.
  • 9.6% had PSA 4-10 ng/mL, 1.9% had PSA >10 ng/mL; 1.7% diagnosed with prostate cancer within a year.

Conclusions:

  • Age-specific PSA reference ranges are necessary.
  • Current data suggest a universal PSA reference range may be suitable across racial/ethnic groups.
