Cancer patients' awareness of clinical trials, perceptions on the benefit and willingness to participate: Korean perspectives.
To understand patients' perceptions of clinical trials (CTs) is the principal step in the enrollment of patients to CTs. However, these perceptions in eastern countries are very rare. From 12 February 2007 to 13 April 2007, we consecutively distributed the questionnaire to 842 cancer patients who initiated a first cycle of chemotherapy regardless of each treatment step in the Seoul National University Hospital. Younger age, higher educational degree, higher economic status, and possession of private cancer insurance were related with significantly higher awareness of CTs (P=0.001, P=0.006, P=0.002, and P=0.009, respectively). However, unlike awareness, perceptions on benefits of CTs were not changed according to age, educational degree, and economic status (P=0.709, P=0.920, and P=0.847, respectively). Willingness was also not changed according to age, educational degree, economic status, and private cancer insurance (P=0.381, P=0.775, P=0.887, and P=0.392, respectively). Instead, males and heavily treated patients had more positive perceptions on benefits (P=0.002 and P=0.001, respectively) and more willingness to participate in CTs (OR=1.17, 1.14-2.75: OR=1.59, 1.01-2.51, respectively). In summary, cancer patients' awareness of CTs, perceptions on the benefit in CTs, and willingness to participate are differently influenced by diverse medical and social conditions. This information would be very helpful for investigators to properly conduct CTs in eastern cancer patients.
