One of the many areas of online promise lies in providing information to the public about clinical trial availability and eligibility criteria. This is particularly important for patients with cancer, a group that would benefit from increased, reliable access to trial information. Using a combination of MEDLINE and Web searching, James Till, Robert Phillips and Alejandro Jadad attempted to detail the completeness of online databases of breast cancer clinical trials available in Canada. The most complete database was the Physician Data Query (PDQ) Clinical Trials Database of the US National Cancer Institute, which identified 86% of trials. Canada's most comprehensive online site identified 29%.
"Our results suggest there is no comprehensive online database of cancer clinical trials in Canada," conclude the authors, who add that future studies should examine incentives to motivate the online listing of trials.
