title: Racial differences in a prostate cancer screening study.
abstract: OBJECTIVE
  We attempted to determine whether black men have a higher prostate cancer prevalence and more advanced disease.
  
  
  METHODS
  We screened 17,157 white and 804 black men 50 years old or older by serum prostate specific antigen measurement and digital rectal examination. We recommended biopsy when either test was suspicious.
  
  
  RESULTS
  Black men had a higher prevalence of elevated prostate specific antigen (13.1 versus 8.9%) and cancer (5.1 versus 3.2%) than white men, and a higher prevalence of clinically but not pathologically advanced cancer. Fewer black men in lower income zip codes complied with recommendations for biopsy.
  
  
  CONCLUSIONS
  In our screening study black men had a higher prevalence of detectable cancer. However, unlike in clinical studies there was no striking racial difference in advanced cancer stage at diagnosis.
