The standard approach for documenting symptomatic adverse events (AEs) in cancer clinical trials involves investigator reporting using the National Cancer Institute's (NCI's) Common Terminology Criteria for Adverse Events (CTCAE). Because this approach underdetects symptomatic AEs, the NCI issued two contracts to create a patient-reported outcome (PRO) measurement system as a companion to the CTCAE, called the PRO-CTCAE. This Commentary describes development of the PRO-CTCAE by a group of multidisciplinary investigators and patient representatives and provides an overview of qualitative and quantitative studies of its measurement properties. A systematic evaluation of all 790 AEs listed in the CTCAE identified 78 appropriate for patient self-reporting. For each of these, a PRO-CTCAE plain language term in English and one to three items characterizing the frequency, severity, and/or activity interference of the AE were created, rendering a library of 124 PRO-CTCAE items. These items were refined in a cognitive interviewing study among patients on active cancer treatment with diverse educational, racial, and geographic backgrounds. Favorable measurement properties of the items, including construct validity, reliability, responsiveness, and between-mode equivalence, were determined prospectively in a demographically diverse population of patients receiving treatments for many different tumor types. A software platform was built to administer PRO-CTCAE items to clinical trial participants via the internet or telephone interactive voice response and was refined through usability testing. Work is ongoing to translate the PRO-CTCAE into multiple languages and to determine the optimal approach for integrating the PRO-CTCAE into clinical trial workflow and AE analyses. It is envisioned that the PRO-CTCAE will enhance the precision and patient-centeredness of adverse event reporting in cancer clinical research.
Background This study examined racial/ethnic differences among patients in clinical trial (CT) enrollment, refusal rates, ineligibility, and desire to participate in research within the National Cancer Institute's Community Cancer Centers Program (NCCCP) Clinical Trial Screening and Accrual Log. Methods Data from 4509 log entries were evaluated in this study. Four logistic regression models were run using physical/medical conditions, enrollment into a CT, patient eligible but declined a CT, and no desire to participate in research as dependent variables. Results Age ≥ 65 (OR=1.51, CI: 1.28 -1.79), males (OR=2.28, CI: 1.92 – 2.71), and non-Hispanic black race (OR=1.53, CI: 1.2 – 1.96) were significantly associated with more physical/medical conditions. Age ≥ 65 was significantly associated with lower CT enrollment (OR=0.83, CI: 0.7 - 0.98). Males (OR=0.78, CI: 0.65 -0.94) and a higher grade level score for consent form readability (OR=0.9, CI: 0.83 - 0.97) were significantly associated with lower refusal rates. Consent page length ≥ 20 was significantly associated with lower odds of “no desire to participate in research” among CT decliners (OR=0.75, CI: 0.58 – 0.98). Conclusion : There were no racial/ethnic differences in CT enrollment, refusal rates, or “no desire to participate in research” as the reason given for CT refusal. Higher odds of physical/medical conditions were associated with older age, males, and non-Hispanic blacks. Better management of physical/medical conditions before and during treatment may increase the pool of eligible patients for CTs. Future work should examine the role of co-morbidities, sex, age, and consent form characteristics on CT participation.
Purpose To prospectively compare outcomes and processes of hospital-based early palliative care with standard care in surgical oncology patients (N = 152). Methods A randomized, mixed methods, longitudinal study evaluated the effectiveness of a hospital-based Pain and Palliative Care Service (PPCS). Interviews were conducted presurgically and at follow-up visits up to 1 year. Primary outcome measures included the Gracely Pain Intensity and Unpleasantness Scales and the Symptom Distress Scale. Qualitative interviews assessed social support, satisfaction with care, and communication with providers. Survival analysis methods explored factors related to treatment crossover and study discontinuation. Models for repeated measures within subjects over time explored treatment and covariate effects on patient-reported pain and symptom distress. Results None of the estimated differences achieved statistical significance; however, for those who remained on study for 12 months, the PPCS group performed better than their standard of care counterparts. Patients identified consistent communication, emotional support, and pain and symptom management as positive contributions delivered by the PPCS. Conclusions It is unclear whether lower pain perceptions despite greater symptom distress were clinically meaningful; however, when coupled with the patients’ perceptions of their increased resources and alternatives for pain control, one begins to see the value of an integrated PPCS.
Although recent scientific advances have improved our understanding of basic biological mechanisms underlying chemotherapy-induced peripheral neuropathy (CIPN), few interventions are available to prevent or treat CIPN. Although some biological targets from preclinical studies show promise in nonhuman animal models, few targets have been translated to successful clinical trials. To address this problem, the National Cancer Institute’s Symptom Management and Health-Related Quality of Life Steering Committee convened a meeting of experts in the CIPN and oncology symptom management fields to participate in a Clinical Trials Planning Meeting (CTPM). Investigators presented data from preclinical and translational studies for possible CIPN interventions; these were evaluated for readiness of randomized clinical trial testing by experts, and recommendations were provided. Breakout sessions were convened to discuss and develop future studies. The CTPM experts concluded that there is compelling evidence to move forward with selected pharmacological and nonpharmacological clinical trials for the prevention and treatment of CIPN. Several key feasibility issues need to be addressed, however. These include identification of optimal outcome measures to define the CIPN phenotype, establishment of parameters that guide the evaluation of clinically meaningful effects, and adoption of approaches for inclusion of translational and biomarker and/or genetic measures. The results of the CTPM provide support for conducting clinical trials that include both pharmacological and nonpharmacological approaches, alone or in combination, with biomarkers, genetics, or other measures designed to inform underlying CIPN mechanisms. Several working groups were formed to design rigorous CIPN clinical trials, the results of which are ongoing.
In response to a 2005 NIH solicitation, sixteen investigators received funding to test interventions that would reduce the barriers that prevent cancer patients from receiving adequate and appropriate symptom management therapies. Since the awards have been issued, the investigators have met two times and have identified a number of challenges to implementing their respective studies. A survey was conducted that focused on their experiences with hiring and retaining study personnel, gaining Institutional Review Board (IRB) approval, incurring unexpected costs, challenges to accruing participants, and a listing of standard measures used in the study. The survey was completed online by the Principal Investigator (PI) for each project in late 2006 and the initial results were confirmed one year later by resending the initial survey and by a follow up phone call. All but one PI completed the survey. Obtaining Institutional Review Board (IRB) approval, hiring and recruiting research personnel, establishing subcontracts and accruing research subjects were the primary challenges experienced by the investigators. This palliative care solicitation achieved more than its original intent of stimulating research in overcoming barriers to delivering cancer symptom management, palliative and end-of-life care. From a survey on the challenges and issues that emerged from their projects, grantees were able to identify specific hurdles and their unique solutions that may help other investigators as they plan their program of research.
