title: Differences in attitudes between patients with primary colorectal cancer and patients with secondary colorectal cancer: is it reflected in their willingness to participate in drug trials?
abstract: Recruitment of patients into drug trials is essential in order to evaluate new treatments. Knowing why patients enter drug trials and their fears regarding them can be used in future research to ensure good recruitment and provide a supportive atmosphere for patients. Forty patients with colorectal cancer and 30 patients with colorectal liver metastases were asked to participate in a drug trial involving the oral consumption of a diet-derived agent of unknown therapeutic action. All patients agreeing or refusing to participate were asked to complete a short questionnaire with a series of options detailing the reasons behind their decision. Patients with colorectal hepatic metastases were motivated by altruism in entering the trial (e.g. helping others, helping the investigator) and displayed a realistic expectation that the drug would give little direct benefit to them. Patients with primary colorectal tumours were motivated by more 'selfish' reasons such as helping themselves and displayed an unrealistic expectation concerning any therapeutic benefit from the trial drug. Over 90% of all patients polled stated that their decision was made after reading the patient information leaflet. Patients with different stages of the same disease have very different fears and anticipations of drug trials, which need to be addressed specifically. The importance of the initial contact is demonstrated. Unrealistic expectations regarding the trial drug are common despite clear information to the contrary.
