Attitudinal barriers to participation in oncology clinical trials: factor analysis and correlates of barriers

Effects of socioeconomic status on enrollment in clinical trials for cancer: A systematic review

BACKGROUND

To achieve equitable access to cancer clinical trials (CCTs), patients must overcome structural, clinical, and attitudinal barriers to trial enrollment. The goal of this systematic review was to study the relationship between socioeconomic status (SES), assessed either by direct or proxy measures, and CCT enrollment.

METHODS

The review team and medical librarian developed search strategies for each database to identify studies for this systematic review, which was conducted according to PRISMA guidelines. Inclusion criteria were as follows: studies published in relevant scientific journals between January 2000 and July 2022, primary sources, English literature, and studies conducted in the US. Sixteen studies fulfilled the inclusion criteria and were reviewed. The risk of bias assessment was conducted independently by two reviewers using the Newcastle Ottawa scale.

RESULTS

The initial search yielded 4070 citations, and 16 studies were included in our review. Four of the studies included used patient reported annual income as a measure of SES, while the remaining 12 studies used patient zip code as a proxy measurement of SES. Consistent with our hypothesis, 13 studies showed a positive association between high SES (patient-reported or proxy measurement) and CCT enrollment. Two studies showed a negative association, and one study showed no relationship.

CONCLUSIONS

The existing literature suggests that low SES is associated with lower participation in CCT. The small number of studies identified on this topic highlights the need for additional research on SES and other barriers to CCT participation.

Operational Metrics for the ELAINE 2 Study Combining a Traditional Approach With a Just-in-TIME Model

PURPOSE

There are numerous barriers to enrollment in oncology biomarker-driven studies.

METHODS

The ELAINE 2 study (ClinicalTrials.gov identifier: NCT04432454) is an open-label phase 2 study of lasofoxifene combined with abemaciclib in patients with advanced or metastatic estrogen receptor-positive/human epidermal growth factor receptor 2-negative breast cancer with an ESR1 mutation. ELAINE 2 opened clinical sites by using a Traditional approach, which activated a site before patient identification, and the Tempus TIME Trial network, which opened a site only after identifying an eligible patient. This manuscript presents the operational metrics comparing the Traditional and TIME Trial site data.

RESULTS

The study enrolled patients over 34 weeks and 16 sites (six Traditional and 10 TIME Trial) participated. Duration for full clinical trial agreement execution for Traditional sites and TIME Trial sites averaged 200.5 (range, 142-257) and 7.6 days (range, 2-14), respectively. Institutional review board approval time for Traditional sites and TIME Trial sites was 27.5 (range, 12-71) and 3.0 days (range, 1-12), respectively. Duration from study activation to first consent was 33.3 (range, 18-58) and 8.8 days (range, 1-35) for Traditional and TIME Trial sites, respectively. The first patient on study was at a TIME Trial site 115 days before a Traditional site and the first seven patients enrolled were at TIME Trial sites. Traditional sites consented 23 and enrolled 16 patients, while TIME Trial sites consented 16 and enrolled 13. The trial enrolled 29 patients in 8.5 months with the anticipated enrollment duration being 12-18 months.

CONCLUSION

The TIME Trial network opened earlier and enrolled the first study patients. These results demonstrate that the Just-in-TIME model, along with a Traditional model, can improve enrollment in biomarker-driven studies.

Knowledge and Attitudes of Guam Residents towards Cancer Clinical Trial Participation

(1) Background: Currently there are no cancer clinical trials in Guam, where CHamoru people suffer the highest rates of cancer mortality, and interest to do so is growing. This study investigated the knowledge and attitudes of Guam residents towards cancer clinical trial participation prior to implementation. (2) Methods: A telephone survey was developed, tested, and conducted among Guam resident adults, 18 years of age and older. Survey questions were summarized by descriptive statistics. Logistic regression models were used to investigate the associations between Guam residents' demographics and their clinical trial knowledge and attitudes. Adjusted odds ratios (aOR) and associated 95% confidence intervals (CI) were calculated. (3) Results: One hundred fifty-two people participated in the survey, most of whom were CHamoru (47.0%). Fifty-three percent had heard the term 'clinical trial'; 73.7% would take part in a trial if they had cancer; and 59.9% believed they would receive good quality treatment from a trial offered in Guam. CHamoru were more likely than Whites to associate out-of-pocket expenses with clinical trial participation (aOR = 5.34, 95% CI = 1.68-17.00). Physician ethnicity was important to 30% of non-Whites and significantly associated with those who spoke a language other than English (aOR = 3.40, 95% CI = 1.29-8.95). Most people (65.0%) did not believe clinical trials participants were 'guinea pigs'. (4) Conclusion: Though knowledge about cancer clinical trials is limited, attitudes were primarily positive towards participating in cancer clinical trials offered in Guam. Future delivery of cancer clinical trials will benefit from identifying potential barriers to recruitment and adopting an approach suited to Guam's population.

Patient Experience in Clinical Trials: Quality of Life, Financial Burden, and Perception of Care in Patients With Multiple Myeloma or Lymphoma Enrolled on Clinical Trials Compared With Standard Care

PURPOSE

Patients' concerns regarding clinical trial (CT) participation include apprehension about side effects, quality of life (QoL), financial burden, and quality of care.

METHODS

We prospectively evaluated the experience of patients with multiple myeloma or lymphoma who were treated on CTs (CT group, n = 35) versus patients treated with standard approaches (non-CT group, n = 88) focusing on QoL, financial burden of care, and patients' perception of quality of care over a 1-year period.

RESULTS

There were no significant differences in any of the patient-reported outcomes in CT versus non-CT groups. We observed an initial decline in overall QoL in the first 3 months across both groups, driven primarily by physical and functional well-being. QoL gradually improved and was above baseline by month 12. Patients reported highest improvement in the functional well-being subdomain. Patients in both groups reported high satisfaction with the quality of care received, and there were no differences in overall satisfaction, communication with team, or access to care. At baseline, 16%-19% of patients reported financial burden, which increased to a peak of 33% in the CT group and to 49% in the non-CT group over the course of 1 year. There was no significant difference in financial burden in the two groups overall. Most of the patients reported getting all the care that was deemed medically necessary in both groups. However, a significant proportion of patients reported having to make other kinds of financial sacrifices because of their cancer (CT group: 33% of patients at baseline and 21%-40% over 1 year; non-CT group: 19% at baseline and 25%-36% over 1 year).

CONCLUSION

Patients treated on CTs reported comparable QoL and quality of care with the non-CT group. A high proportion of patients reported financial burden over time in both groups. Our findings can serve as a guide to educate patients regarding CT participation and highlight the need to address the significant financial burden experienced by patients with cancer.

Motivations and barriers for healthy participants to participate in herbal remedy clinical trial in Tanzania: A qualitative study based on the theory of planned behaviour

BACKGROUND

The success of any randomized clinical trial relies on the willingness of people to be recruited in the trial. However, 90% of all clinical trials worldwide have been reported to have failed to recruit the required number of trial participants within the scheduled time. This study aimed to qualitatively explore the motivations and barriers for healthy participants to participate in herbal remedy clinical trials in Tanzania.

MATERIALS AND METHODS

This study used a qualitative descriptive research design based on the theory of planned behaviour. A total of five Focus Group Discussions (FGD) were conducted at Bagamoyo Clinical Trial Facility from 29 to 30 May 2021. Each group consisted of 5 to 10 participants. The participants of the study were 30 healthy males aged 18 to 45 male who participated in the clinical trial that evaluated the safety, tolerability, and efficacy of Maytenus Senegalensis. The focus group discussions were recorded audio-recorded. Verbatim transcription and thematic analysis were performed on the data.

RESULTS

The prominent motivations mentioned were the opportunity for self-development, altruism, flexible study visit schedule, and financial compensation. Furthermore, the Participants' mothers and friends were reported as those most likely to approve of participation in an herbal remedy. The most mentioned barriers were inconvenience related to time commitment requirements, possible side effects, inflexible study visit schedule, and having other commitments. Moreover, the participants' father was reported to be more likely to disapprove of participation in a clinical trial of herbal remedy clinical trial.

CONCLUSIONS

The results of this study showed that the motivations and barriers of healthy participants to participate in clinical trials of herbal remedies are varied and that participants are motivated by more than financial gains. The identified motivations and barriers can be used as a guideline to improve the design of recruitment and retention strategies for herbal remedy clinical trials.

Health Disparities in Recruitment and Enrollment in Research

Despite advances in thoracic oncology research, the benefits of new discoveries are not universally experienced. A lack of representation of racial/ethnic minorities and individuals of low socioeconomic status in clinical trials and thoracic research contributes to persistent health care disparities. It is critical that improved racial, ethnic, and socioeconomic diversity is achieved in our trials and research, if we are to attain generalizability of findings and reduction of health care disparities. Culturally tailored and community-based approaches can help improve recruitment and enrollment of marginalized groups in thoracic research, which is an essential step toward achieving health equity and advancing medical science.

Tailored Messages About Research Participation: Using an Interactive Information Aid to Improve Study Recruitment

After a diagnosis of cancer (or other serious disease), patients may be asked to consider joining a clinical trial. Because most people are unfamiliar with the scientific concepts that are necessary to the provision of meaningful informed consent, patient education is necessary. Increasing knowledge alone is not sufficient; understanding how clinical trial participation aligns with personal circumstances and knowledge is central to the decision-making process. In this study, 302 cancer patients and survivors evaluated an interactive information aid (IA) designed to inform their decision to join a research study or clinical trial by providing tailored information to patients' responses to questions pertaining to seven key barriers or facilitators of clinical trial participation. The development of the IA was done with input from the authors' Clinical Translational Science Institute; linked components of the IA were vetted by members and leaders of the institution's NCI-designated comprehensive cancer center. Results of the study indicated that the information aid was successful in significantly reducing fears and increasing knowledge, attitudes, perceived behavioral control, and behavioral intentions about research participation relative to a control condition. Thus, an interactive information aid that provides information that is responsive to patients' values, knowledge, and personal circumstances can help patients to be better prepared to consider a decision about research participation.

Clinical Trial Participation: A Pilot Study of Patient-Identified Barriers

BACKGROUND

Clinical trial enrollment in the United States is lacking, particularly among older adult and ethnic and racial minority populations.

OBJECTIVES

The aim of the current study was to identify patient-related barriers to clinical trial participation using a mixed-methods patient survey and to offer insights to develop evidence-based implementation strategies to address these barriers.

METHODS

A retrospective survey was conducted of patients who were not interested in participating in a clinical trial to quantify the reasons these patients chose not to participate. Directed qualitative content analysis was used to identify themes that emerged from the write-in responses.

FINDINGS

The greatest patient-reported barriers were misperceptions about placebos, a desire to not feel like a human guinea pig, uncertainty surrounding clinical trial treatment effectiveness compared to standard care, and concerns about additional appointments or tests. Oncology nurses can address patient enrollment barriers by providing targeted education and participating in the informed consent process.

Financial toxicity in cancer care: origins, impact, and solutions

Financial toxicity describes the financial burden and distress that can arise for patients, and their family members, as a result of cancer treatment. It includes direct out-of-pocket costs for treatment and indirect costs such as travel, time, and changes to employment that can increase the burden of cancer. While high costs of cancer care have threatened the sustainability of access to care for decades, it is only in the past 10 years that the term "financial toxicity" has been popularized to recognize that the financial burdens of care can be just as important as the physical toxicities traditionally associated with cancer therapy. The past decade has seen a rapid growth in research identifying the prevalence and impact of financial toxicity. Research is now beginning to focus on innovations in screening and care delivery that can mitigate this risk. There is a need to determine the optimal strategy for clinicians and cancer centers to address costs of care in order to minimize financial toxicity, promote access to high value care, and reduce health disparities. We review the evolution of concerns over costs of cancer care, the impact of financial burdens on patients, methods to screen for financial toxicity, proposed solutions, and priorities for future research to identify and address costs that threaten the health and quality of life for many patients with cancer.

The mental health impacts of receiving a breast cancer diagnosis: A meta-analysis

BACKGROUND

Receiving a breast cancer diagnosis can be a turning point with negative impacts on mental health, treatment and prognosis. This meta-analysis sought to determine the nature and prevalence of clinically significant psychological distress-related symptoms in the wake of a breast cancer diagnosis.

METHODS

Ten databases were searched between March and August 2020. Thirty-nine quantitative studies were meta-analysed.

RESULTS

The prevalence of clinically significant symptoms was 39% for non-specific distress (n = 13), 34% for anxiety (n = 19), 31% for post-traumatic stress (n = 7) and 20% for depression (n = 25). No studies reporting breast cancer patients' well-being in our specific time frame were found.

CONCLUSION

Mental health can be impacted in at least four domains following a diagnosis of breast cancer and such effects are commonplace. This study outlines a clear need for mitigating the impacts on mental health brought about by breast cancer diagnosis. CRD42020203990.

Facilitators, Challenges, and Messaging Strategies for Hispanic/Latino Populations Participating in Alzheimer's Disease and Related Dementias Clinical Research: A Literature Review

Alzheimer's disease and Alzheimer's disease-related dementias (AD/ADRD) disproportionally affect Hispanic and Latino populations, yet Hispanics/Latinos are substantially underrepresented in AD/ADRD clinical research. Diverse inclusion in trials is an ethical and scientific imperative, as underrepresentation reduces the ability to generalize study findings and treatments across populations most affected by a disease. This paper presents findings from a narrative literature review (N = 210) of the current landscape of Hispanic/Latino participation in clinical research, including the challenges, facilitators, and communication channels to conduct culturally appropriate outreach efforts to increase awareness and participation of Hispanics/Latinos in AD/ADRD clinical research studies. Many challenges identified were systemic in nature: lack of culturally relevant resources; staffing that does not represent participants' cultures/language; eligibility criteria that disproportionately excludes Hispanics/Latinos; and too few studies available in Hispanic/Latino communities. The paper also details facilitators and messaging strategies to improve engagement and interest among Hispanics/Latinos in AD/ADRD research, starting with approaches that recognize and address the heterogeneity of the Hispanic/Latino ethnicity, and then, tailor outreach activities and programs to address their diverse needs and circumstances. The needs identified in this article represent longstanding failures to improve engagement and interest among Hispanics/Latinos in AD/ADRD research; we discuss how the field can move forward learning from the experiences of the COVID-19 pandemic.

Systematic review of financial burden assessment in cancer: Evaluation of measures and utility among adolescents and young adults and caregivers

The cost of cancer care is rising and represents a stressor that has significant and lasting effects on quality of life for many patients and caregivers. Adolescents and young adults (AYAs) with cancer are particularly vulnerable. Financial burden measures exist but have varying evidence for their validity and reliability. The goal of this systematic review is to summarize and evaluate measures of financial burden in cancer and describe their potential utility among AYAs and their caregivers. To this end, the authors searched PubMed, Embase, the Cochrane Library, CINAHL, and PsycINFO for concepts involving financial burden, cancer, and self-reported questionnaires and limited the results to the English language. They discarded meeting abstracts, editorials, letters, and case reports. The authors used standard screening and evaluation procedures for selecting and coding studies, including consensus-based standards for documenting measurement properties and study quality. In all, they screened 7250 abstracts and 720 full-text articles to identify relevant articles on financial burden. Eighty-six articles met the inclusion criteria. Data extraction revealed 64 unique measures for assessing financial burden across material, psychosocial, or behavioral domains. One measure was developed specifically for AYAs, and none were developed for their caregivers. The psychometric evidence and study qualities revealed mixed evidence of methodological rigor. In conclusion, several measures assess the financial burden of cancer. Measures were primarily designed and evaluated in adult patient populations with little focus on AYAs or caregivers despite their increased risk of financial burden. These findings highlight opportunities to adapt and test existing measures of financial burden for AYAs and their caregivers.

Automated Electronic Health Record-Based Tool for Identification of Patients With Metastatic Disease to Facilitate Clinical Trial Patient Ascertainment

PURPOSE

To facilitate identification of clinical trial participation candidates, we developed a machine learning tool that automates the determination of a patient's metastatic status, on the basis of unstructured electronic health record (EHR) data.

METHODS

This tool scans EHR documents, extracting text snippet features surrounding key words (such as metastatic, progression, and local). A regularized logistic regression model was trained and used to classify patients across five metastatic categories: highly likely and likely positive, highly likely and likely negative, and unknown. Using a real-world oncology database of patients with solid tumors with manually abstracted information as reference, we calculated sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV). We validated the performance in a real-world data set, evaluating accuracy gains upon additional user review of tool's outputs after integration into clinic workflows.

RESULTS

In the training data set (N = 66,532), the model sensitivity and specificity (% [95% CI]) were 82.4 [81.9 to 83.0] and 95.5 [95.3 to 96.7], respectively; the PPV was 89.3 [88.8 to 90.0], and the NPV was 94.0 [93.8 to 94.2]. In the validation sample (n = 200 from five distinct care sites), after user review of model outputs, values increased to 97.1 [85.1 to 99.9] for sensitivity, 98.2 [94.8 to 99.6] for specificity, 91.9 [78.1 to 98.3] for PPV, and 99.4 [96.6 to 100.0] for NPV. The model assigned 163 of 200 patients to the highly likely categories. The error prevalence was 4% before and 2% after user review.

CONCLUSION

This tool infers metastatic status from unstructured EHR data with high accuracy and high confidence in more than 75% of cases, without requiring additional manual review. By enabling efficient characterization of metastatic status, this tool could mitigate a key barrier for patient ascertainment and clinical trial participation in community clinics.

Empowering patients in decision-making in radiation oncology - can we do better?

The decision as to whether or not a patient should receive radiation therapy as part of their cancer treatment is based on evidence‐based practice and on recommended international consensus treatment guidelines. However, the merit of involving the patients' individual preferences and values in the treatment decision is frequently overlooked. Here, we review the current literature pertaining to shared decision‐making (SDM) in the field of radiation oncology, including discussion of the patient's perception of radiation therapy as a treatment option and patient involvement in clinical trials. The merit of decision aids during the SDM process in radiation oncology is considered, as are patient preferences for active or passive involvement in decisions about their treatment. Clarity of terminology, a better understanding of effective strategies and increased resources will be needed to ensure SDM in radiation oncology becomes a reality.

Barriers to Participation in Therapeutic Clinical Trials as Perceived by Community Oncologists

PURPOSE

Despite considerable research on the barriers to enrollment in cancer therapeutic trials, few studies have elicited barriers from the perspective of community physicians, who provide the majority of cancer care. The purpose of this study was to characterize barriers to and facilitators of cancer therapeutic trials as perceived by oncologists in community practices.

METHODS

Twenty semistructured interviews were conducted with oncologists at six community sites affiliated with City of Hope National Medical Center from March to June 2018. Responses were recorded digitally and transcribed. Data were analyzed using qualitative content analysis.

RESULTS

Of the 20 participants, 4 (20%) were women, 13 (65%) had > 10 years of practice experience, and 16 (80%) reported that < 5% of their patients were enrolled in a therapeutic trial. Participants identified four system-level barriers: lack of appropriate trials for community-based settings, insufficient infrastructure support, restrictive eligibility criteria, and financial limitations; three physician-level barriers: lack of awareness of available trials, lack of knowledge of trial details, and lack of time; and two patient-level barriers: patient burden and negative beliefs/attitudes toward research. Efforts aimed to increase trial availability, clinical trial support personnel, and physician knowledge were identified as major facilitators.

CONCLUSION

Community oncologists face numerous complex, multifaceted barriers to cancer therapeutic trial enrollment. Although expanding clinical research beyond the academic setting allows access to a larger and more diverse patient population, increasing generalizability and relevance of trial findings, there remains a substantial need for new strategies to improve cancer research delivery in the community.

Management algorithms for prostate-specific antigen progression in prostate cancer: Biochemical recurrence after definitive therapy and progression to non-metastatic castrate-resistant prostate cancer

INTRODUCTION

Current prostate cancer (PCa) guidelines primarily focus on localized or metastatic PCa. A multidisciplinary genitourinary oncology panel determined that additional guidance focusing on monitoring and management of biochemical recurrence (BCR) following radical therapy and non-metastatic castration-resistant prostate cancer (nmCRPC) was warranted.

METHODS

The most up-to-date national and international guidelines, consensus statements, and emerging phase 3 trials were identified and used to inform development of algorithms by a multidisciplinary genitourinary oncology panel outlining optimal monitoring and treatment for patients with non-metastatic PCa.

RESULTS

A total of eight major national and international guidelines/consensus statements published since 2015 and three phase 3 trials were identified. Working group discussions among the multidisciplinary genitourinary oncology panel led to the development of two algorithms: the first addressing management of patients with BCR following radical therapy (post-BCR), and the second addressing management of nmCRPC. The post-BCR algorithm suggests consideration of early salvage treatment in select patients and provides guidance regarding observation vs. intermittent or continuous androgen-deprivation therapy (ADT). The nmCRPC algorithm suggests continued ADT and monitoring for all patients, with consideration of treatment with apalutamide or enzalutamide for patients with high-risk disease (prostate-specific antigen [PSA] doubling time of ≤ 10 months).

CONCLUSIONS

Two treatment algorithms have been developed to guide the management of non-metastatic PCa and should be considered in the context of local guidelines and practice patterns.

Overcoming Barriers to Clinical Trial Enrollment

Clinical trials are imperative for testing novel cancer therapies, advancing the science of cancer care, and determining the best treatment strategies to enhance outcomes for patients with cancer. However, barriers to clinical trial enrollment contribute to low participation in cancer clinical trials. Many factors play a role in the persistently low rates of trial participation, including financial barriers, logistical concerns, and the lack of resources for patients and clinicians to support clinical trial enrollment and retention. Furthermore, restrictive eligibility criteria often result in the exclusion of certain patient populations, which thus adds to the widening disparities seen between patients who enroll in trials and those treated in routine practice. Moreover, additional factors, such as difficulty by patients and clinicians in coping with the uncertainty inherent to clinical trial participation, contribute to low trial enrollment and represent key components of the decision-making process. Specifically, patients and clinicians may struggle to assess the risk-benefit ratio and may incorrectly estimate the probability and severity of challenges associated with clinical trial participation, thus complicating the informed consent process. Importantly, research has increasingly focused on overcoming barriers to clinical trial enrollment. A promising solution involves the use of patient navigators to help enhance clinical trial recruitment, enrollment, and retention. Although clinical trials are essential for improving and prolonging the lives of patients with cancer, barriers exist that can impede trial enrollment; yet, efforts to recognize and address these barriers and enhance trial enrollment are being investigated.

The Role of Oncology Nurses in Discussing Clinical Trials

PURPOSE/OBJECTIVES

To describe oncology nurses' experiences discussing clinical trials with their patients, and to assess barriers to these discussions.
.

RESEARCH APPROACH

A qualitative study designed to elicit narratives from oncology nurses. 
.

SETTING

Community- and academic-based oncology clinics throughout the United States.
.

PARTICIPANTS

33 oncology nurses involved in direct patient care in community-based and large hospital-based settings. The sample was drawn from members of the Oncology Nursing Society. 
.

METHODOLOGIC APPROACH

In-depth interviews were conducted and analyzed using a 
immersion/crystallization approach to identify themes and patterns. The analyses highlight specific issues, examples, and contexts that present challenges to clinical trial discussions with patients.
.

FINDINGS

Oncology nurses view their roles as patient educators and advocates to be inclusive of discussion of clinical trials. Barriers to such discussions include lack of knowledge and strategies for addressing patients' common misconceptions and uncertainty about the timing of discussions.
.

INTERPRETATION

These data indicate that enabling nurses to actively engage patients in discussions of clinical trials requires educational interventions to build self-efficacy and close knowledge gaps. 
.

IMPLICATIONS FOR NURSING

Oncology nurses can play a critical role in advancing cancer care by supporting patients in decision making about clinical trial participation. This will require training and education to build their knowledge, reduce barriers, and increase their self-efficacy to fulfill this responsibility in various clinical settings.

Relationship between phase I study duration and symptom burden

PURPOSE

Phase I clinical trials are critical to development of cancer therapeutics. Adverse events (AEs) and symptom burden contribute to early treatment withdrawal, and it is often difficult to ascertain whether these events are disease- or treatment-related. Regardless, early withdrawal may delay determination of the effectiveness of potential new therapies. We sought to characterize the reasons for early treatment termination to identify potential modifiable events.

METHODS

A retrospective chart review was conducted on solid tumor patients enrolled in institutional phase I clinical trials from 2003 to 2013 through the Case Comprehensive Cancer Center.

RESULTS

Two hundred fifty-five patients were included in the analysis. The mean duration on study was 78.4 days (SD 63.4 days), and 23% of the patients were on study ≤ 30 days. Patients experienced an average of 25.1 AEs, of which 46.9% were non-laboratory. Constitutional symptoms (29.3%), gastrointestinal symptoms (24%), and pain (12.8%) were the most common non-laboratory AEs. Disease progression (57.6%) was the most common reason for study discontinuation, followed by adverse events (16.5%). Approximately 13% of the patients discontinued treatment for other reasons, of which 41.7% were identified as related to symptom burden on further review. Increased rates of AEs negatively correlated with duration on study (r = - 0.331; p < 0.01).

CONCLUSIONS

AEs may lead to early termination of trial participation and confound clinical assessment of investigational treatments. Designing interventions to reduce AE burden may extend duration on trial, affect the recommended phase II dose, and benefit the quality of life of participants on phase I trials.

Conducting Biobehavioral Research in Patients With Advanced Cancer: Recruitment Challenges and Solutions

Despite significant advances in cancer treatment and symptom management interventions over the last decade, patients continue to struggle with cancer-related symptoms. Adequate baseline and longitudinal data are crucial for designing interventions to improve patient quality of life and reduce symptom burden; however, recruitment of patients with advanced cancer in longitudinal research is difficult. Our purpose is to describe challenges and solutions to recruitment of patients with advanced cancer in two biobehavioral research studies examining cancer-related symptoms. Study 1: Symptom data and peripheral blood for markers of inflammation were collected from newly diagnosed patients receiving chemotherapy on the first day of therapy and every 3-4 weeks for up to 6 months. Study 2: Symptom data, blood, and skin biopsies were collected from cancer patients taking epidermal growth factor receptor inhibitors at specific time points over 4 months. Screening and recruitment results for both studies are summarized. Timing informed consent with baseline data collection prior to treatment initiation was a significant recruitment challenge for both the studies. Possible solutions include tailoring recruitment to fit clinic needs, increasing research staff availability during clinic hours, and adding recruitment sites. Identifying solutions to these challenges will permit the conduct of studies that may lead to identification of factors contributing to variability in symptoms and development of tailored patient interventions for patients with advanced cancer.

Barriers to Cancer Clinical Trial Participation Among Saudi Nationals: A Cross-Sectional Study

This study aims to determine the factors that act as barriers to Saudi cancer patients in participating in a clinical trial (CT). A total of 244 patients from two different tertiary level hospitals (King Khalid University Hospital and King Fahad Medical City Hospital) in Riyadh, Saudi Arabia, participated in this cross-sectional study. The participants were interviewed by a trained researcher between September and November 2015. All respondents answered a three-part questionnaire which includes demographics, clinical information, and questions related to awareness of CTs, willingness to participate, and factors affecting participation in CTs. The mean age of the participants was 50.83, and 57 % of the participants were females. Most of the participants (63.5 %) were currently being treated for cancer, and 28 % were diagnosed with breast cancer followed by colorectal cancer. Health status or quality of life was self-reported as acceptable by 27.9 % of the participants, and 25 % of the participants at stage II of cancer. The factors that act as barriers to Saudi cancer patients in participating in a CT can be categorized into patient- and physician-related factors. Patient factors include lack of awareness, misconception and fear in participating in CTs; physician-related factors comprise of lack of encouragement from physician to patients in participating in a CT. The study identified few major barriers to participation in CTs. Increased patient awareness and recruitment strategies are required to increase accrual of patients including training for physicians and disseminating easy-to-read tools to the public.

Barriers to Clinical Trial Enrollment in Racial and Ethnic Minority Patients With Cancer

BACKGROUND

Clinical trials that study cancer are essential for testing the safety and effectiveness of promising treatments, but most people with cancer never enroll in a clinical trial - a challenge exemplified in racial and ethnic minorities. Underenrollment of racial and ethnic minorities reduces the generalizability of research findings and represents a disparity in access to high-quality health care.

METHODS

Using a multilevel model as a framework, potential barriers to trial enrollment of racial and ethnic minorities were identified at system, individual, and interpersonal levels. Exactly how each level directly or indirectly contributes to doctor-patient communication was also reviewed. Selected examples of implemented interventions are included to help address these barriers. We then propose our own evidence-based intervention addressing barriers at the individual and interpersonal levels.

RESULTS

Barriers to enrolling a diverse population of patients in clinical trials are complex and multilevel. Interventions focused at each level have been relatively successful, but multilevel interventions have the greatest potential for success.

CONCLUSION

To increase the enrollment of racial and ethnic minorities in clinical trials, future interventions should address barriers at multiple levels.

Financial Burden of Cancer Clinical Trial Participation and the Impact of a Cancer Care Equity Program

INTRODUCTION

Cancer clinical trial (CT) participation rates are low and financial barriers likely play a role. We implemented a cancer care equity program (CCEP) to address financial burden associated with trial participation. We sought to examine the impact of the CCEP on CT enrollment and to assess barriers to participation.

METHODS

We used an interrupted time series design to determine trends in CT enrollment before and after CCEP implementation. Linear regression models compared trial enrollment before and after the CCEP. We also compared patient characteristics before and after the CCEP and between CCEP and non-CCEP participants. We surveyed CCEP and non-CCEP participants to compare pre-enrollment financial barriers.

RESULTS

After accounting for increased trial availability and the trends in accrual for prior years, we found that enrollment increased after CCEP implementation (18.97 participants per month greater than expected; p < .001). A greater proportion of CCEP participants were younger, female, in phase I trials, lived farther away, had lower incomes, and had metastatic disease. Of 87 participants who completed the financial barriers survey, 49 CCEP and 38 matched, non-CCEP participants responded (63% response rate). CCEP participants were more likely to report concerns regarding finances (56% vs. 11%), medical costs (47% vs. 14%), travel (69% vs. 11%), lodging (60% vs. 9%), and insurance coverage (43% vs. 14%) related to trial participation (all p < .01).

CONCLUSION

CT participation increased following implementation of the CCEP and the program enrolled patients experiencing greater financial burden. These findings highlight the need to address the financial burden associated with CT participation.

IMPLICATIONS FOR PRACTICE

Financial barriers likely discourage patients from participating in clinical trials. Implementation of a cancer care equity program (CCEP) seeking to reduce financial barriers by assisting with travel and lodging costs was associated with increased trial accrual. The CCEP provided assistance to patients particularly in need, including those living farther away, those with lower incomes, and those reporting financial barriers related to trial participation. These findings suggest that financial concerns represent a major barrier to patient participation in clinical trials and underscore the importance of efforts to address these concerns.

The global conduct of cancer clinical trials: challenges and opportunities

The nature of clinical research has changed substantially over the last 2 decades, evolving from being centered almost exclusively in developed countries to a more global scenario that is increasingly involving less developed regions of the world. Pharmaceutical companies and some academic cooperative groups have been conducting challenging, large pivotal registration studies with multinational participation. The much more needed globalization of academic research demands particular attention and represents a worthwhile subject for a more profound discussion. The requirement of large sample sizes and the potential for fast recruitment leading to a speedy completion of clinical studies are probably the most important factors that have fueled globalization of studies. Reduced operational costs and the ability to expedite the regulatory approval of drugs in various countries or regions are also important drivers. Globalization of research should be seen as having a much wider effect in the societies involved, in particular, when we consider public health, economic, social, and ethical implications. Most importantly, the process of expanding the network of clinical research sites also fosters the integration and the development of closer relationships among investigators at a global level. We consider this an essential element that should remain a prominent element in the discussion. In this article, we address the underlying reasons for globalization and we highlight some of the scientific and ethical concerns arising as a consequence. Finally, some strategies to address and mitigate the challenges of conducting multinational clinical research are proposed.

Patients' knowledge and perceived understanding - Associations with consenting to participate in cancer clinical trials

Recruitment to clinical trials is essential. The aims of the study were to investigate associations between patients' informed consent to participate in a cancer clinical trial and knowledge and perceived understanding of the trial. Furthermore, associations between demographic factors and consent to participate and knowledge and perceived understanding of information about the trial were studied.

Methods

The patients were recruited in connection to a visit at the oncology clinic for information about a drug trial. The Quality of Informed Consent questionnaire was mailed to the patients after they had decided about participation in the trial. The associations of demographic factors and "knowledge" and "perceived understanding" were analysed using linear regression models.

Results

A total of 125 patients were included. Higher levels of "knowledge" and "understanding" were found to be associated with consent to participate in a clinical trial, both in the univariate and multivariate analyses (p = 0.001). None of the tested demographic factors were related to consent to participate. No statistically significant associations between any of the demographic factors and knowledge or perceived understanding scores were found.

Conclusion

The results indicate that interventions that increase patients' knowledge and perceived understanding might improve participation rates in clinical trials.

Exploring research participation among cancer patients: analysis of a national survey and an in-depth interview study

Background

Inequalities in cancer research participation are thought to exist with certain groups under-represented in research populations; however, much of the evidence is based on small-scale studies. The aim of this study was to explore data from in-depth interviews with cancer patients and a large national survey to investigate variation in who is asked to participate in research and who takes part.

Methods

Factors associated with research discussion and participation were explored in National Cancer Patient Experience Survey data using multivariate logistic regression and during in-depth interviews with 25 breast cancer patients.

Results

Survey data were available for 66,953 cancer patients; 30.4 % reported having discussions about, and 18.9 % took part in, research. Barriers to participation at staff, patient and trust level were evident; for example, staff were less likely to discuss research with older patients, Asian and black patients were less likely to take part and patients treated at specialist or teaching trusts had higher levels of discussion and participation. Interviews showed that patients’ willingness to participate changed over time and was not synonymous with participation as some were ineligible.

Conclusion

Some patient groups were less likely to have discussions about or participate in research. Analysis of this variation vis-à-vis the composition of the patient population may be useful to ensure that there is equity regarding the potential benefits of research participation and that research findings are applicable to target populations in the translational model.

Adolescent and young adult patients with cancer: a milieu of unique features

Adolescent and young adult (AYA) patients with cancer are a unique category of patients who, depending on age at time of diagnosis, might receive treatment from oncologists specializing either in the treatment of children or adults. In the USA, AYA oncology generally encompasses patients 15-39 years of age. AYA patients with cancer typically present with diseases that span the spectrum from 'paediatric' cancers (such as acute lymphoblastic leukaemia [ALL] and brain tumours) to 'adult' tumours (such as breast cancer and melanoma), as well as cancers that are largely unique to their age group (such as testicular cancer and bone tumours). Research indicates that outcomes of AYA patients with cancer are influenced not only by the treatment provided, but also by factors related to 'host' biology. In addition to the potential biological and cancer-specific differences between AYAs and other patients with cancer, AYA patients also often have disparate access to clinical trials and suffer from a lack of age-appropriate psychosocial support services and health services, which might influence survival as well as overall quality of life. In this Review, these issues are discussed, with a focus on two types of AYA cancer--ALL and melanoma--highlighting findings arising from the use of emerging technologies, such as whole-genome sequencing.
