Cancer clinical trials enable the development of novel agents for the potential benefit of cancer patients.

Enrolment in a trial offers patients the chance of superior efficacy coupled to the risk of unanticipated toxicity. Socioeconomic deprivation is associated with poor cancer outcomes. In the developed world, the gap between the most and least deprived is widening. This mini-review explores the evidence regarding socioeconomics and access to cancer trials, highlighting the underrepresentation of deprived patients, and exploring reasons for this disparity.

Although worldwide life expectancy is improving, the gap in life expectancy between the most and least affluent is widening in the developed world Thomas et al, ; Krieger et al, This separation may largely be driven by the health impact of high-risk lifestyle activities such as smoking, poor diet and inactivity, which vary in prevalence by socioeconomic status SES.

However, differential access to care, especially in countries where universal health care is not the norm, may also be a dominant factor in SES-related life expectancy disparities Disparities in cancer care, Cancer care is similarly subject to the same SES-related health disparity factors The burden of cancer care on lower SES populations is increased, they are less likely to attend cancer screening programmes, and suffer from poorer outcomes ; Renshaw et al, ; Herndon et al, As interventional clinical research is integral to much of modern cancer care, in this review we explore ways in which access to cancer clinical trials CCTs may be influenced by common health and sociodemographic inequalities.

While the exposure of patients to effective novel treatments is a benefit of clinical trials, this must be balanced against the fact that in randomised studies patients may experience greater inconveniences trips, tests, etc. Of note, the level of negative clinical research outcomes may be underestimated in practice due to publication bias in favour of CCTs reporting positive outcomes Tam et al, However, evidence supports RCTs offering at least equivalence to standard treatment Gross et al, , and enrolment of patients in CCTs is considered by physicians to be of value and importance Somkin et al, If we accept the premise that CCTs are overall of benefit to patients and the advancement of cancer care, then they should, in theory, be offered to all eligible patients for reasons of equity.

In addition, for CCTs to deliver conclusions that are applicable in practice they should be drawn from populations for whom the treatment is intended. In an ideal world the mix of patients in clinical trials should reflect the mix of patients receiving treatment for cancer in general.

In the United States recognition of disparities in clinical trial access has lead to national policy strategies. In keeping with this, the Federal Drug Administration FDA began mandating gender analysis in clinical trial data and reversed its requirement that women of childbearing age be excluded from early phase trials. Despite this progress, minorities, the elderly, adolescents, patients from rural communities, and in regions without universal health care the uninsured remain underrepresented Kwiatkowski et al, They found that higher socioeconomic levels were associated with an increased accrual to clinical trials.

Associated factors included: income increase of 0. They also noted that patients enrolled onto clinical trials were less likely to be uninsured, and more likely to have Medicare in Medicare policy was changed to cover the routine costs of trial participation. Data from Maryland between and revealed lower accrual to trials with increasing deprivation scores.

Cancer Patients Share Their Experience With Immunotherapy Clinical Trials

Those enrolled were less likely to be uninsured, or covered by Medicaid or private insurance, compared with the general population. Recruitment was found to be associated with social class Baquet et al, Income was also notably associated with trial participation in an internet-based survey of patients asked about their cancer treatment decisions Unger et al, Among the survey respondents, both discussion of a trial and subsequent participation were associated with being younger, wealthier, and more highly educated.

Both education attainment and wealth estimates are most commonly used in models of SES. Education alone is also considered as a valid surrogate of SES Herndon et al, In addition, even among those enrolled on trials lower educational attainment was associated with poorer outcomes Herndon et al, In the setting of early phase cancer trials there is evidence that referral is biased significantly in favour of the more affluent population, with enrolment on a trial after contact with the trials clinic not affected by SES Mohd Noor et al, Lack of education about cancer and CCTs is a frequently reported barrier to trials access Mills et al, ; Ford et al, Less readily defined are aspects of culture and belief that influence patient decision-making.

It is notable that this may lead to assumptions about willingness to participate, exacerbating recruitment bias. Therefore, it is important to note that surveys of cancer patients in regions of the United States do report equal willingness to participate in CCTs among AAs, Hispanics, and whites, despite a greater reported fear of participation in randomised trials Byrne et al, Addressing these complex social barriers likely requires tailored community engagement.

The use of ethnicity as a variable to examine underrepresentation of other groups of patients in CCTs is emerging as an oversimplification. There is growing evidence that outcome differences attributed to race may in fact be more dependent on SES Du et al, , with SES a key barrier to enrolment Sateren et al, Consideration of both race and SES when addressing inequality enables clearer delineation of true barriers within communities.

Many CCTs mandate a certain level of global fitness, as well as standard measures for organ function. Education level, as a surrogate of SES, has been shown to inversely correlate with leading causes of death, and as noted in the CALGB trial with worsened outcomes within clinical trials Jemal et al, These eligibility criteria barriers are a frequently cited cause of non-participation for underrepresented populations in CTCs Mills et al, ; Ford et al, It has been reported that people from lower socioeconomic groups are less likely to attend for cancer screening programmes, and present at later stages of disease Ionescu et al, ; Renshaw et al, Certainly, late presentation, and late initial therapy, could increase the risk of co-morbidity hindering recruitment to trials.

The information offered about clinical trials may be in an inappropriate form for many except those patients with high educational attainment. The language used in patient information and consent forms has long been a concern: a study in found that consent forms consistently failed readability guidelines, with language complexity hindering understanding for people with low reading levels Paasche-Orlow et al, This inevitably affects those with lower educational attainment disproportionately, and may result in refusal to participate in trials.

In areas or groups in which minority languages are commonly spoken, with the assumption that these may be more associated with lower SES, ease and speed of access to translators and to either long or short form translated consent forms may be an additional factor influencing relevant communication about clinical trials.

Financial concerns are of relevance even in areas with universal health care such as the United Kingdom. Hidden costs, such as travel to and from clinics, the need for extra childcare, and the loss of income due to missed work will be more significant for those of lower SES. These costs are compounded in areas with no universal health-care provision by concerns about insurance coverage of participation in clinical trials, or indeed about whether any care is available where the patient is uninsured.

In the United States, indigent insurance programmes may restrict care to specific hospitals in the region, which may not be the same hospitals with thriving clinical research programmes. Indeed, in the United States and many countries, clinical trials are not universally distributed across geographic areas. More affluent populations may be more likely to seek out physicians at centres with clinical trial portfolios. While patients with good insurance may choose to travel they still need accurate information on where specific novel therapies may be available West and Camidge, National trials registry sites such as www.

Financial coercion via compensation for trial participation may disproportionately affect poorer patients—if you are wealthy being paid to participate is not an incentive—for this reason inclusion of financial incentives in CTCs is rarely considered as ethical.

To be initially referred for consideration of a trial, the referring clinician must consider the patient a candidate. There are several reasons why they may not do so. First, as mentioned above, the patient may suffer from multiple comorbidities, which the clinician seen as incompatible with clinical trial involvement. Third, the clinician may make decisions, either consciously or sub-consciously, about the appropriateness of referral for a trial based on assumptions about their socioeconomic characteristics.

Physicians in specialist centres are more orientated towards research than those based in community general hospitals Ford et al, Physicians are more likely to refer patients for CCTs than surgeons Klabunde et al, Education about trials in general and available CCTs in particular is key to overcoming referrer bias, as is a focus on communication skills for front-line clinicians.

Ford et al, More directed strategies to overcome referrer barriers to CCT access are complex, and in practice prove difficult to deliver Michaels et al, A final clinician-driven obstacle to enrolment is the complex nature of CCTs. A clinician may not have time to provide adequate explanation and counseling about the trial, particularly in for-profit private practice models in some countries.

Improving the access of patients from lower socioeconomic groups to cancer screening, diagnosis and therapy will increase their representation on clinical trials. General health-care policy such as national smoking cessation programmes and alcohol awareness campaigns will go some way to decrease the levels of comorbidities disproportionally affecting lower socioeconomic groups. These are, however, long-term national strategies not influenced by clinical trial stakeholders. Improving the recruitment from the current pool may be affected through improved communication, both between health-care professional and patient, and from clinical trial investigators to referring physicians.

Cancer Clinical Trials: Proactive Strategies

Social and cultural barriers can and have been addressed by innovative approaches; prostate cancer screening information in AA barber shops, flexible timing of screening interventions for busy working mothers and educating clergy to address barriers to cancer care to name but a few Sadler et al, ; Hart et al, ; Germino et al, These approaches are labour intensive, potentially costly and may only access small populations, however, multiple small solutions to this large problem could be the way change is affected.

It is important that all patients are considered for clinical trial enrolment, and that any exclusion from recruitment is based upon trial entry criteria. To that end referring clinicians should be made aware of all potential trials available. Proactive strategies to encourage referral of patients from lower SES groups may be of benefit, but are challenging to implement Michaels et al, For patients with low reading levels, a video presentation rather than written material may be useful Unger et al, Improved readability of leaflets with simple language may help in conveying complex concepts to all patients regardless of education level.

From , all insurance providers in United States will be obliged to cover standard costs of clinical trials. Where the cost of travel is a limitation, satellite clinics closer to patients' homes, as well as expanding portfolios of trials in rural practice settings away from large cancer centres, may improve access for more deprived populations. Finding methods to engage minority groups with cultural sensitivity is key to helping reduce the impact of pre-conceptions among underprivileged groups regarding safety and applicability of CCTs Germino et al,
