BACKGROUND: The purpose of this study was to describe the distribution of serum prostate-specific antigen (PSA) among American men and to estimate the number of prevalent cases of biopsy detectable prostate cancer among men with normal serum PSA. METHODS: We analyzed data of the National Health and Nutrition Examination Survey 2001-2002 (NHANES 2001-2002) data and combined these results with published data from the Prostate Cancer Prevention Trial (PCPT). RESULTS: Most men in the US have a serum PSA < or = 4.0 ng/ml, and mean and median serum PSA values rise steadily with age. There are an estimated 1,607,585 (95% CI 1,370,848-1,844,322) prevalent cases of biopsy detectable prostate cancer in men aged 62-85 years with a serum PSA < or = 4 ng/ml. Among men aged 62-75 years, there are an estimated 1,252,143 (95% CI 1,054,677-1,449,609) prevalent cases, including an estimated 195,499 (95% CI 140,234-250,764) high-grade tumors. CONCLUSION: A large number of prevalent cases of biopsy detectable prostate cancer exist in American men with a normal PSA. Copyright 2005 Wiley-Liss, Inc.
