Knowledge and attitudes towards clinical trials among women with ovarian cancer: results of the ACTO study

Background Despite several initiatives by research groups, regulatory authorities, and scientific associations to engage citizens/patients in clinical research, there are still obstacles to participation. Among the main discouraging aspects are incomplete understanding of the concepts related to a clinical trial, and the scant, sometimes confused, explanations given. This observational, cross-sectional multicenter study investigated knowledge, attitudes and trust in clinical research. We conducted a survey among women with ovarian cancer at their first follow-up visit or first therapy session, treated in centers belonging to the Mario Negri Gynecologic Oncology (MaNGO) and Multicenter Italian Trials in Ovarian Cancer (MITO) groups. A questionnaire on knowledge, attitudes and experience was assembled ad hoc after a literature review and a validation process involving patients of the Alliance against Ovarian Cancer (ACTO). Results From 25 centers 348 questionnaire were collected; 73.5% of responders were 56 years or older, 54.8% had a high level of education, more than 80% had no experience of trial participation. Among participants 59% knew what clinical trials were and 71% what informed consent was. However, more than half did not know the meaning of the term randomization. More than half (56%) were in favor of participating in a clinical trial, but 35% were not certain. Almost all responders acknowledged the doctor's importance in decision-making. Patients' associations were recognized as having a powerful role in the design and planning of clinical trials. Conclusions This study helps depict the knowledge and attitudes of women with ovarian cancer in relation to clinical trials, suggesting measures aimed at improving trial culture, literacy and compliance, and fresh ways of communication between doctors and patients.

Automated summary

Despite efforts to engage citizens/patients in clinical research, there are obstacles to participation. This study investigated the knowledge, attitudes, and trust in clinical research among women with ovarian cancer. The results showed that most patients had some understanding of clinical trials and informed consent, but lacked knowledge about randomization. The majority of patients were willing to participate in clinical trials and recognized the importance of doctors in decision-making.
