Racial and ethnic differences in the biology of breast cancer tumors
Date:11/29/2007

ATLANTA Scientists from the National Cancer Institute are looking into the racial and ethnic differences in the biology of breast cancer tumors and are presenting their findings this week at the American Association for Cancer Research conference on The Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, being held November 27-30 in Atlanta.

While observed differences in breast cancer survival between African-American and Caucasian women are often attributed to disparities in socio-demographic and access to healthcare factors, recent studies have shown that, even when accounting for these factors, African-American women still fare worse than Caucasian women. In a study of how genes are activated in breast cancer tumors, researchers at the National Cancer Institute (NCI) have demonstrated that there are discernable racial and ethnic differences in the biology of these tumors.

In particular, their findings revealed that many genes related to tumor immunobiology, inflammation, and angiogenesis are expressed differently in tumors from African-American women than in those from Caucasian women. The data could indicate that inflammation and other immune system processes play a stronger role in the development and progression of cancer in African-American women, says Damali Martin, Ph.D., postdoctoral fellow at NCIs Center for Cancer Research.

According to Martin, African-American breast cancer patients on the whole tend to have a greater prevalence of a more aggressive form of breast cancer, one that is less likely to respond to hormone therapy and more likely to spread to lymph nodes.

Martin and her colleagues examined gene expression profiles an indicator of which genes are active -- in microdissected breast tumors from 35 patients with invasive breast cancer, including 18 African Americans and 17 Caucasians.

The researchers identified racial discrepancies in the gene prof
