We appreciate the interest of Roach et al. in our analysis of
survival among black and white prostate cancer patients in the San
Francisco Bay Area (1). The investigators have raised
important issues, and we welcome the opportunity to respond to them.
They argue against biologic factors as an explanation for poorer
stage-specific survival of black prostate cancer patients compared with
white patients. Instead, they argue that the observed higher death
rates in blacks can be explained completely by racial differences in
socioeconomic barriers, such as inadequate access to health care, to
good treatment, and to health education leading to
