Oncology physician and nurse practices and attitudes regarding offering clinical trial results to study participants.

Despite recent interest on the part of advocates and researchers of oncology clinical trials in sharing study results, participants in these trials are not routinely informed about the results. We identified oncology physicians and nurses through the Cancer and Leukemia Group B database and surveyed them about sharing clinical trial results with participants. Of 1977 eligible members, 796 (40.3%) responded to the mailed survey, 497 (62.4%) of whom reported that they offer trial results to participants less than one-fifth of the time. A total of 576 (72.4%) of responders believed that most patients want to know the results of studies, and 634 (79.7%) of responders expressed willingness to offer results to most study participants in the future, believing that most patients want to know trial results and that routinely offering results would not have a negative effect on patients. Concerns of some responders about routinely offering trial results included negative emotional effect on patients, patient difficulty understanding the information, and resources required to offer the results. Of concern, 16.2% (129/796) of responders believed an obligation to offer results to study participants would make them less likely to enroll patients on studies. Future studies should consider sharing trial results with patients and evaluating the process and its effect on both patients and clinicians.
