Although clinical trial research is required for the development of improved treatment strategies, very few cancer patients participate in these studies. The purpose of this study was to describe psychosocial barriers to clinical trial participation among oncologists and their cancer patients. A survey was distributed to all medical oncologists in Pennsylvania and a subset of their patients. Relevant background information and assessment of practical and psychosocial barriers to clinical trial participation were assessed. Among 137 oncologists and 170 patients who completed the surveys, 84% of patients were aware of clinical trials, and oncologists and patients generally agreed that clinical trials are important to improving cancer treatment. However, oncologists and patients were more likely to consider clinical trials in advanced or refractory disease. When considering 7 potential barriers to clinical trials, random assignment and fear of receiving a placebo were ranked highly by both patients and oncologists. Patients identified fear of side effects as the greatest barrier to clinical trial participation, whereas oncologists ranked this psychosocial barrier as least important to their patients. Overall, the study found that although oncologists and patients are aware of clinical trials and have favorable attitudes toward them, psychosocial barriers exist for patients that may impact participation in clinical trials. Furthermore, important discrepancies exist between the perceptions of oncologists and those of patients regarding what the psychosocial barriers are. We concluded that characterizing oncologist and patient perceived barriers can help improve communication and decision making about clinical trials, such that participation may be optimized.

    • "It is also a significant recognition that patient autonomy is a value that to act upon entails allowing each patient to decide about trial participation to the extent of their ability. In the past and especially for community physicians, convenience, cost, and necessary follow-up visits in addition to age were perceived as barriers for their patients and so trials were not discussed [13,39]. Go and colleagues [15] describe as reality that about a quarter of community physicians think risks outweigh benefits at this stage and do not discuss trials with their patients - a clear and relevant factor in physician triage.

    ABSTRACT: Background Enrollment in interventional therapeutic clinical trials is a small fraction of all patients who might participate given reasonable access. Methods A hierarchical approach is utilized in measuring staged participation from trial availability to patient enrollment. Our framework suggests that concern for justice comes in the design and eligibility criteria for clinical trials; attention to beneficence is given in the eligibility and physician triage stages. The remaining four stages rely on respect for persons. An example is given where reasons for nonparticipation or barriers to participation in prostate cancer clinical trials are examined within the framework. In addition, medical oncology patients with an initial six month consultation are tracked from one stage to the next by race using the framework to assess participation comparability. Results We illustrated seven transitions from being a patient to enrollment in a clinical trial in a small study of prostate cancer cases who consulted SKCCC Medical Oncology Department in early 2010. Pilot data suggest transition probabilities as follows: 65% availability, 84% eligibility, 92% patient triage, 89% trials discussed, 45% patient interested, 63% patient consented, and 92% patient enrolled. The average transition probability was 77.7%. The average transition probability, patient-trial-fit was 50%; opportunity was 51%, and acceptance was 66.7%. Trial availability, patient interest and patient consented were three transitions that were below the average; none were statistically significant. Conclusions The framework may serve to streamline comprehensive reporting of clinical trial participation to the benefit of patients and the ethical conduct of clinical trials.

    ABSTRACT: Patients invited to take part in a clinical trial may evoke an archetype on which they may base their decision of adherence to participation, instead of on the study itself. A 17-item, multiple choice questionnaire was developed, tested and then administered to 102 Italian-speaking patients with advanced lung or breast cancers who had never been exposed to participation in a trial. The questionnaire was answered by all patients. Eighty-five percent were positive about trial participation. Demographic factors did not influence patients' willingness to participate. Trust in the investigator (76%) or in the institute (64%) and hope of receiving a new chance for cure (78%) were cited as reasons to accept participation. A minority was concerned by potential conflicts of interest (31%) or the thought of being 'guinea pigs' (36%), and feared that doctors were interested in advancing their own research, even though there were more efficient drugs available (28%). Fifty percent feared receiving a little-known medicine, and 76% considered that a thorough explanation of toxicity/safety of the proposed treatment helped them decide. Several prejudices, fears and some hopes have been captured by the questionnaire. Understanding such specifics will improve patient information leading patients to a more conscious motivation in deciding whether to participate in a clinical trial.

    ABSTRACT: There have been few prospective observational studies which recruited older newly-diagnosed cancer patients, and of these only some have reported information on the number needed to screen to recruit their study sample, and the number and reasons for refusal and drop-out. This paper reports on strategies to recruit older newly-diagnosed cancer patients prior to treatment into an observational prospective pilot study and to retain them during a six-month period. Medical charts of all patients in the Segal Cancer Centre aged 65 and over were screened and evaluated for inclusion. Several strategies to facilitate recruitment and retention were implemented. Reasons for exclusion, refusal and loss to follow-up were recorded. Descriptive statistics were used to report the reasons for refusal and loss to follow-up. A non-response analysis using chi-square tests and t-tests was conducted to compare respondents to those who refused to participate and to compare those who completed the study to those who were lost to follow-up. A feedback form with open-ended questions was administered following the last interview to obtain patient's opinions on the length of the interviews and conduct of this pilot study. 3060 medical charts were screened and 156 eligible patients were identified. Of these 112 patients participated for a response rate of 72%. Reasons for refusal were: feeling too anxious (40%), not interested (25%), no time (12.5%), too sick (5%) or too healthy (5%) or other reasons (5%). Ninety-one patients participated in the six-month follow-up (retention 81.3%), seven patients refused follow-up (6.2%) and fourteen patients died (12.5%) during the course of the study. The median time to conduct the baseline interview was 45 minutes and 57% of baseline interviews were conducted at home. Most patients enjoyed participation and only five felt that the interviews were too long. It was feasible to recruit newly-diagnosed cancer patients prior to treatment although it required considerable time and effort. Once patients were included, the retention rate was high despite the fact that most were undergoing active cancer treatment.
