Resource Details

PDQ is the National Cancer Institute's comprehensive cancer information database. It contains peer-reviewed summaries on cancer treatment, screening, prevention, genetics, and supportive care; a registry of approximately 3,500 open and 15,000 closed cancer clinical trials from around the world; and a directory of over 400 individuals who provide services related to cancer genetics (cancer risk assessment, genetic counseling, genetic susceptibility testing, and others).

PDQ's cancer information summaries are peer reviewed and updated monthly by six editorial boards comprised of specialists in adult treatment, pediatric treatment, complementary and alternative medicine, supportive care, screening and prevention, and genetics. The Boards review current literature from more than 70 biomedical journals, evaluate relevance, and synthesize clear summaries. Many of the summaries are also available in Spanish.

The PDQ Cancer Clinical Trials Registry provides trial descriptions, site and contact information for cancer clinical trials conducted in the US and internationally. The registry facilitates trial registration to meet the requirements of the Food and Drug Modernization Act of 1997 by registering trials sponsored by NCI, cancer centers, and other sponsors in the National Library of Medicine's ClinicalTrials.gov database.
