University of Minnesota study refutes belief that black men have more aggressive prostate cancer
Date:9/17/2007

A University of Minnesota study of prostate cancer tumors from Caucasian and African-American men has shown no evidence that the cancer is more aggressive in black men. Lead investigator Akhouri Sinha, a professor of genetics, cell biology, and development and research scientist at the Minneapolis VA Medical Center, said the belief that black mens tumors are more aggressive is based on studies that failed to match patients properly and used only indirect means to measure tumor aggressiveness. The work will be published in Anticancer Research Sept. 21 (vol. 27, issue 5A, pp. 3135-3142).

In previous studies of prostate tumors, those in black patients tended to be larger and at a more advanced stage, and black men had higher blood levels of prostate specific antigen (PSA), a substance produced by the prostate that, at high levels, points to the possibility of prostate cancer. But all these criteria are interrelated and could be the result of delayed diagnosis or medical care, Sinha said.

Previous studies showing differences in prostate cancers among races require re-evaluation because inconsistent criteria were used in selection of patients, he said. Our data shows that for patients receiving similar treatment, African-American patients are not following up with their doctors as opposed to Caucasians, and this difference is highly significant. Also, Caucasian patients are four times as likely to receive additional treatment after prostatectomy. Cancer does not discriminate on the basis of race, religion, national origin, or caste system, like people do. Invasiveness of prostate cancer is not race-dependent.

According to Sinha, what is needed is a comparison of the innate aggressiveness of tumors that have been matched by criteria relevant to a diagnosis of cancer as well as treatment after prostatectomy.

Drawing on the resources of the Minneapolis Veterans Affairs Medical Center, Sinha selected preserved slices of tumors from
