Women and African-Americans are under-represented in lung cancer clinical trials, clinicians report in the Journal of Cancer. \'\'The lack of participation by minorities and women shut them out of the next generation of potentially life-saving treatment,\'\' warned Dr. Wei Du in comments to Reuters.' It also makes it all the more difficult for clinicians to translate treatment benefits and risks found in a clinical trial to these under-represented patient populations,\'\' the researcher added. Du, from Wayne State University in Detroit , and colleagues reviewed the medical records of 427 lung cancer patients who were eligible to participate in lung cancer clinical trials at Detroit \'s Karmanos Cancer Institute between 1994 and 1996. The group comprised 175 African-Americans and 252 from other races and 59 percent were male.
