As the first year of the grant was dedicated to study start-up activities, no results from the main study are yet available. A descriptive epidemiology study comparing racial trends in prostate cancer incidence rates in Illinois and the United States was undertaken. The objective of this study was to examine trends in Illinois and US prostate cancer rates to ascertain whether trends were similar by race. Incidence rates were obtained from Illinois State Cancer Registry and SEER. Rate ratios were estimated for three periods 1986-1990 pre-PSA, 1991-1995 PSA-uptake, and 1996-2000 PSA-widespread use. Incidence rates peaked in the mid-i 1990s. Rate differences between the two regions narrowed in 1994 and 1995. African- Americans had higher incidence rates than Caucasians throughout. The post-1996 incidence pattern in Illinois, however, was unique with the incidence rates in African-Americans declining and the racial disparities narrowing. This suggests more effective prostate cancer screening is taking place in Illinois African-American populations than US African-American populations, although differential risk profiles may also be operating.
