In Reply We thank Gerke et al for their interest in our article and appreciate the opportunity to address their concerns.

Black men are diagnosed more often with prostate cancer (PCa) than white men in the United States. Thus, even if PCa-specific mortality (PCSM) outcomes are similar, the disease burden is greater for black men. Our article did not address this important disparity.1 We stated that “our data do not address the biological propensity to develop an incident prostate cancer…which may contribute to the higher rate ratio of prostate cancer death in black men.”1
