Do African American men have lower survival from prostate cancer compared with White men? A meta-analysis.

Prostate cancer is the second leading cause of cancer-related mortality in men. This meta-analysis was conducted to investigate the relationship between race and survival from prostate cancer. A systematic review of articles published from 1968 to 2007 assessing survival from prostate cancer was conducted. Analysis of unadjusted studies reported that African American men have an increased risk of all-cause mortality (hazard ratio [HR] = 1.47, 95% confidence interval [CI] = 1.31-1.65, p < .001). However, examination of adjusted studies identified no difference (HR = 1.07, 95% CI = 0.94-1.22, p = .308). No statistically significant difference was observed in prostate cancer-specific survival in both analyses using unadjusted (HR = 1.11, 95% CI = 0.94-1.31, p = .209) and adjusted studies (HR = 1.15, 95% CI = 0.95-1.41, p = .157). This meta-analysis concludes that there are no racial differences in the overall and prostate cancer-specific survival between African American and White men.
