Background
Eligibility criteria and screening procedures are designed to optimize the scientific yield and maximize the safety of clinical trials. However, they may also heighten trial complexity, hinder enrollment, decrease generalizability, and increase costs. We analyzed the types and number of eligibility criteria and screening procedures among thoracic oncology clinical trials sponsored or endorsed by the Eastern Cooperative Oncology Group (ECOG).
Methods
We identified trials and obtained protocols from the ECOG website. Eligibility criteria were grouped and categorized as comorbidity (classified by organ system), administrative requirements, prior treatment, and measurable disease requirement. Associations between trial characteristics and eligibility criteria were analyzed using Kruskal-Wallis and Wilcoxon tests.
Results
A total of 74 lung cancer trials activated 1986–2016 were identified. The total number of eligibility criteria was associated with trial principal therapy (median 9 for surgical, 18 for radiation, 20 for medical; P=0.02), trial primary endpoint (median 20 for OS, 28 for PFS, 17 for other; P=0.001), number of therapies (P=0.05), and year of activation (median 16 for 1986–1995, 19 for 1996–2005, 27 for 2006–2016; P<0.001). The increase in trial eligibility requirements over time was limited to medical therapy trials. Over time, there was also an increase in blood test screening procedures (P=0.05), but not for imaging, cardiac assessment, or pulmonary function screening procedures.
Conclusions
The number of eligibility criteria and screening procedures in medical therapy lung cancer clinical trials continues to rise. Continued efforts to simplify protocol eligibility and procedures are warranted to promote trial adherence, enrollment, completion, and generalizability.
Opposing incidence trends in younger versus older Hispanics may reflect generational differences in CRC risk by birth cohort, as well as environmental exposures and lifestyle-related risk factors associated with immigration and acculturation.
Although there are many similarities between clinic and research teams, we also identified key differences, including perceptions of goal clarity and sharing, understanding and alignment with cancer center goals, and importance of outcomes. Future studies should examine how variation in perceptions and group dynamics between clinic and research teams may impact function and processes of cancer care.
PURPOSE: Effective enrollment and treatment of patients in cancer clinical trials require definition and coordination of roles and responsibilities among clinic and research personnel. MATERIALS AND METHODS: We developed a survey that incorporated modified components of the Survey of Physician Attitudes Regarding the Care of Cancer Survivors. Surveys were administered to clinic nursing staff and research personnel at a National Cancer Institute–designated comprehensive cancer center. Results were analyzed using χ2-tests, t tests, and analyses of variance. RESULTS: Surveys were completed by 105 staff members (n = 50 research staff, n = 55 clinic staff; 61% response rate). Research staff were more likely to feel that they had the skills to answer questions, convey information, and provide education for patients on trials (all P < .05). Both clinic and research staff reported receipt of communication about responsibilities in fewer than 30% of cases, although research staff reported provision of such information in more than 60% of cases. Among 20 tasks related to care of patients in trials, no single preferred model of responsibility assignment was selected by the majority of clinic staff for nine tasks (45%) or by research staff for three tasks (15%). Uncertainty about which team coordinates care was reported by three times as many clinic staff as research staff ( P = .01). There was also substantial variation in the preferred model for delivery of care to patients in trials ( P < .05). CONCLUSION: Knowledge, attitudes, and perception of care and responsibilities for patients on clinical trials differ between and among clinic and research personnel. Additional research about how these findings affect efficiency and quality of care on clinical trials is needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
