Prostate cancer in blacks: an update from the American College of Surgeons' patterns of care studies.

Data from the American College of Surgeons' prostate cancer surveys covering nearly a decade of experience demonstrate that the problem of prostate cancer is unique among black men in the United States. These data show that the distribution of stage at diagnosis changed across the 10-year interval. The data indicate that there have been improvements in the 5-year survival rates of both black and white patients, but the prostate cancer-specific survival of black patients remains significantly poorer than that of whites.
