KLK3 and Familial prostate cancer: There was no published study on prostate cancer morbidity and mortality in Benin, Gambia, and Senegal. Although there was no published study reporting prostate cancer morbidity and mortality in Senegal, Gueye et al. [12] found the clinical characteristics of prostate cancer among the Senegalese (median PSA of 37.0 ng/mL) to be different from American Blacks (median PSA of 6.3 ng/mL) and Whites (median PSA of 6.1 ng/mL); p < 0.001.
