Prostate cancer incidence and mortality rates vary widely between populations, with highest documented rates among African Americans, and lowest rates in Asian populations. It is likely that these differences can be attributed to variation in genetics, environmental exposures, screening patterns, and treatment patterns; however the reasons for these differences have not been fully elucidated.

We invite investigators to contribute original research articles and review articles that will contribute to our understanding of the underlying reasons for population differences in prostate cancer incidence and outcomes. Potential topics include, but are not limited to:

• Role of genetic markers in risk and outcomes, including gene/environment interactions
• Influence of genetic ancestry
• Differences in exposure to risk factors, including diet, occupation, and others
• Differences in treatment modalities and impact on outcomes
• Role of other medical conditions, for example, metabolic syndrome, diabetes, and so forth
• Role of inflammation in prostate cancer etiology
• Latest developments and/or technologies for evaluating epigenetic differences
• Role of treatment, insurance, social exclusion, cultural barriers, and health seeking behaviors
• Pathological differences in disease characteristics by race
