Perceptions and Attitudes of Cancer Patients and Caregivers Towards Enrollment in Clinical Trials in Lebanon

The rates of participation in oncology clinical trials (CTs) are relatively lower in the Middle East compared to other areas in the world. Many social and cultural factors underlie the patients’ reluctance to participate. To probe the knowledge, attitudes, and perceptions of patients with cancer and their caregivers regarding participation in CTs at our tertiary referral center in Lebanon, we interviewed 210 patients and caregivers visiting the outpatient clinics in the Naef Basile Cancer Institute at the American University of Beirut. A questionnaire was derived from literature and administered in Arabic. The study was approved by the Institutional Review Board (IRB). Two hundred individuals agreed to answer the questionnaire. The majority of participants (90.5%) were Lebanese with the remaining being non-Lebanese Arabs. Eighty-nine participants (45%) were aware of the concepts of CTs. Eighty-two respondents (41%) would participate in phase I CTs. Twenty-nine individuals (14.5%) agree to be enrolled in CTs with the approval of their family members only. One hundred twenty-nine subjects (64.5%) stated that they would refuse enrollment in a CT where they might receive placebo. Eighty-eight (44%) of participants considered that medical records could be reviewed for research without consent while 54% agreed that samples collected during clinical workup could be used for research without the consent of the patient. There are several social and demographic correlates for participation in CTs. Raising awareness and overcoming barriers of misconception are keys to promote participation in CTs in Lebanon.
