New strategies required to get blacks and Asians to participate in cancer trials

The better informed people are about cancer clinical trials, the more likely they are overall to consider participating in a trial, according to a UC Davis study published in today's issue of the Journal of Clinical Oncology. However, knowing about cancer clinical trials does not appear to increase participation among black and Asian Americans.
