A survey of breast cancer patients' views on entry into several clinical studies.

During the course of their treatment and follow-up, women with breast cancer are likely to be asked to join a number of different clinical studies. Some local research ethics committees have expressed concerns about entry of individual patients into multiple research studies. A survey was undertaken to improve understanding of patients' own perceptions of participation in several clinical studies. A total of 96 patients who had previously undergone surgery for breast cancer from January to June 2000 were sent a questionnaire 6-12 months after completion of primary treatment. Eighty four per cent of questionnaires were returned of which 62% were from patients who had been approached to enter at least one clinical study. Sixty-four per cent of patients believed that there should not be a limit on the number of clinical studies offered to patients. Furthermore, three quarters of all patients would have considered entering more than one study if adequate explanation and written information were provided. Most patients felt that their participation in a clinical study was worthwhile and no patients surveyed regretted their decision to take part in a study. Almost two-thirds of patients who returned questionnaires believed there should not be a maximum number of studies offered to them. This survey suggests that the majority of patients are prepared to participate in more than one clinical study when adequate information and explanation are provided.
