The purpose of this investigation was to examine changes in pretreatment prostate-specific antigen (PSA), stage, and grade over the past decade as a function of race and geographic region. A multiinstitutional database representing 6,790 patients (1,417 African-American, 5,373 white) diagnosed with nonmetastatic prostate cancer between 1988 and 1997 was constructed. PSA, stage, and grade data were tabulated by calendar year and region, and time trend analyses based on race and region were performed. There was an overall decline of PSA of 0.8%/year, which was significant (P = 0.0001), with a faster rate of decline in African-Americans (1.9%/year) than for whites (0.6%/year). The odds ratio (OR) for a stage shift was 1.09, which was significant (P < 0.0001), and this shift was greater in whites. The OR for an overall grade shift was 1.15, which was significant (P < 0.0001). Although grade and PSA trends were similar for the different regions, there were significant regional differences in stage trends. The implications are that the face of prostate cancer has changed over the past decade; i.e., the distributions of stage, grade, and PSA (the most important prognosticators) have changed. In addition, the countenances of that face are different for whites and African-Americans. For African-Americans, this is good news: the stage, grade, and PSA distributions are more favorable now than before. For whites, the trends are more complex and more dependent on region. These findings should be used for future clinical and health-policy decisions in the screening and treatment of prostate cancer.
