100 per person in high-income countries), and overall public expenditure on health care is still only slightly above 1% of gross domestic product. Out-of-pocket payments, which account for more than three-quarters of cancer expenditures in India, are one of the greatest threats to patients and families, and a cancer diagnosis is increasingly responsible for catastrophic expenditures that negatively affect not only the patient but also the welfare and education of several generations of their family. We explore the complex nature of cancer care systems across India, from state to government levels, and address the crucial issues of infrastructure, manpower shortages, and the pressing need to develop cross-state solutions to prevention and early detection of cancer, in addition to governance of the largely unregulated private sector and the cost of new technologies and drugs. We discuss the role of public insurance schemes, the need to develop new political mandates and authority to set priorities, the necessity to greatly improve the quality of care, and the drive to understand and deliver cost-effective cancer care programmes.

The challenge of cancer in middle-income countries with an ageing population: Mexico as a case study

Ajay Aggarwal; Karla Unger-Saldaña; Grant Lewison; Richard Sullivan

Over the past 20 years, cancer research in India has grown in size and impact. Clinicians, scientists, and government and state policy makers in India have championed cancer research, from studies to achieve low-tech, large-scale health outcomes to some of the most advanced areas of fundamental cancer science. In this paper, we frame public policy discussions about cancer with use of an in-depth analysis of research publications from India. Cancer research in India is a complex environment that needs to balance public policy across many competing agendas. We identify major needs across these environments such as those for increased research capacity and training and protected time for clinical researchers; for more support from states and enhanced collaborative funding programmes from government; for development of national infrastructures across a range of domains (ie, clinical trials, tissue banking, registries, etc); and for a streamlined and rational regulatory environment. We also discuss improvements that should be made to translate research into improvements in cancer outcomes and public health.

Shooting for the Moon or Flying Too Near the Sun? Crossing the Value Rubicon in Precision Cancer Care

Mark Lawler; Declan French; Raymond Henderson; Ajay Aggarwal; Richard Sullivan

Introduction: Lung cancer is the leading cause of years of life lost because of cancer and is associated with the highest economic burden relative to other tumor types. Research remains at the cornerstone of achieving improved outcomes of lung cancer. We present the results of a comprehensive analysis of global lung cancer research between 2004 and 2013 (10 years). Methods: The study used bibliometrics to undertake a quantitative analysis of research output in the 24 leading countries in cancer research internationally on the basis of articles and reviews in the Web of Science (WoS) database. Results: A total of 32,161 lung cancer research articles from 2085 different journals were analyzed. Lung cancer research represented only 5.6% of overall cancer research in 2013, a 1.2% increase since 2004. The commitment to lung cancer research has fallen in most countries apart from China and shows no correlation with lung cancer burden. A review of key research types demonstrated that diagnostics, screening, and quality of life research represent 4.3%, 1.8%, and 0.3% of total lung cancer research, respectively. The leading research types were genetics (20%), systemic therapies (17%), and prognostic biomarkers (16%). Research output is increasingly basic science, with a decrease in clinical translational research output during this period. Conclusions: Our findings have established that relative to the huge health, social, and economic burden associated with lung cancer, the level of world research output lags significantly behind that of research on other malignancies. Commitment to diagnostics, screening, and quality of life research is much lower than to basic science and medical research. The study findings are expected to provide the requisite knowledge to guide future cancer research programs in lung cancer.

Diagnostic delay and survival in high-grade gliomas – evidence of the ‘waiting time paradox’?

Ajay Aggarwal; Naomi Herz; Philip Campbell; Leo Arkush; Susan Short; Jeremy Rees

Mexico is undergoing rapid population ageing as a result of its epidemiological transition. This study explores the interface between this rapid population ageing and the burden of cancer. The number of new cancer cases is expected to increase by nearly 75% by 2030 (107,000 additional cases per annum), with 60% of cases in the elderly (aged ≥ 65). A review of the literature was supplemented by a bibliometric analysis of Mexico’s cancer research output. Cancer incidence projections for selected sites were estimated with Globocan software. Data were obtained from recent national census, surveys, and cancer death registrations. The elderly, especially women and those living in rural areas, face high levels of poverty, have low rates of educational attainment, and many are not covered by health insurance schemes. Out of pocket payments and private health care usage remain high, despite the implementation of Seguro Popular that was designed to achieve financial protection for the lowest income groups. A number of cancers that predominate in elderly persons are not covered by the scheme and individuals face catastrophic expenditure in seeking treatment. There is limited research output in those cancer sites that have a high burden in the elderly Mexican population, especially research that focuses on outcomes. The elderly population in Mexico is vulnerable to the effects of the rising cancer burden and faces challenges in accessing high quality cancer care. Based on our evidence, we recommend that geriatric oncology should be an urgent public policy priority for Mexico.

The media and cancer: education or entertainment? An ethnographic study of European cancer journalists.

Ajay Aggarwal; Rekha Batura; Richard Sullivan

In his last two State of the Union addresses, President Barack Obama has focused on the need to deliver innovative solutions to improve human health, through the Precision Medicine Initiative in 2015 and the recently announced Cancer Moonshot in 2016. Precision cancer care has delivered clear patient benefit, but even for high-impact medicines such as imatinib mesylate (Glivec) in chronic myeloid leukaemia, the excitement at the success of this practice-changing clinical intervention has been somewhat tempered by the escalating price of this ‘poster child for precision cancer medicine (PCM). Recent studies on the costs of cancer drugs have revealed significant price differentials, which are a major causative factor behind disparities in the access to new generations of immunological and molecularly targeted agents. In this perspective, we will discuss the benefits of PCM to modern cancer control, but also emphasise how increasing costs are rendering the current approaches to integrating the paradigm of PCM unsustainable. Despite the ever increasing pressure on cancer and health care budgets, innovation will and must continue. Value-based frameworks offer one of the most rational approaches for policymakers committed to improving cancer outcomes through a public health approach.

UK newspaper reporting of the NHS cancer drugs fund, 2010 to 2015: a retrospective media analysis

Grant Lewison; Ajay Aggarwal; Philip Roe; Henrik Møller; Charlotte A Chamberlain; Richard Sullivan

Abstract Introduction. We present a retrospective single-centre study to determine whether delays in diagnosis of high-grade glioma (HGG) impact on overall survival (OS). Material and methods. Consecutive patients diagnosed with HGG at a single neuroscience centre in 2011 were reviewed. Route of referral and time from initial presentation to diagnosis were analysed and correlated with OS. Results.118 patients were studied – 92 patients with glioblastoma (GBM). Diagnosis of GBM in patients presenting to emergency services was quicker than that through outpatients (8 days vs. 26 days, p < 0.0001), but these patients had significantly worse OS (181 days vs. 386 days p = 0.0075). This trend was observed for the whole cohort (Grade III and GBM), with OS 278 days in patients presenting to emergency services compared with 423 days for patients presenting via outpatients (p = 0.0034). Patients presenting to outpatients were younger (median age: 54 years) compared with patients presenting to emergency services (median age: 62.5 years) (p = 0.0106). There were no other differences between the two groups with respect to the nature of presenting symptoms. Conclusion. Earlier diagnosis is paradoxically associated with a worse OS in GBM. An ‘aggressive’ phenotype with rapid symptomatic deterioration and hence emergency presentation is a poor prognostic factor not influenced by earlier diagnosis.

The media plays a vital role in informing the public about new developments in cancer research and influencing cancer policy. This is no easy task, in view of the myriad of trials and wonder drugs that purport to be the ‘magic bullet’. However, misrepresentation can have profound consequences. In this qualitative study, we sought to understand the interaction between the media and cancer through the perspective of European science journalists by defining their attitudes towards current cancer research and challenges faced when reporting science news. A total of 67 respondents took part in this online survey, which was distributed by the European CanCer Organisation (ECCO) to all its media contacts between June and September 2013. Fifty-three per cent had over 20 years experience in reporting science news stories. The respondents utilised a number of media formats, including newsprint, online services, and radio. Fifty per cent ranked public interest as the greatest influence on their selection of cancer research topics, followed by topicality. Respondents were conscious of being fed ambiguous and exaggerated results from trials by the research community. Sixty-five per cent of respondents would appreciate access to a forum of experts willing to provide comment on new research findings. Seventy per cent highlighted the importance of prompt responses from scientists and researchers during correspondence, and the need to have advance warning of new developments (49%). To conclude – coverage of cancer related issues and scientific advances require greater collaboration between the press and cancer healthcare community to provide both credibility and accountability for the health information disseminated. Key areas include a more precise definition of the research context and differentiation of absolute and relative risks, as well as individual and population risks and an informed discussion about the realities and limitations of cancer care and research.

“Nudge” and the epidemic of missed appointments

Ajay Aggarwal; Joanna Davies; Richard Sullivan

Objective We wished to explore how UK national newspapers had covered the creation and operation of the Cancer Drugs Fund from 2010 to 2015. This was introduced to provide cancer patients in England with access to drugs not appraised or approved by the National Institute for health and Care Excellence. Design We sought stories in nine newspapers from the Factiva database, and copied their salient details to a spreadsheet. They were categorised by whether they were supportive or critical of the Cancer Drugs Fund and their main arguments, which drugs they mentioned and for which cancers. Settings Not applicable Participants Not applicable Main outcome results Press coverage was mainly very positive, arguing for the Cancer Drugs Funds extension to Scotland and Wales, and a bigger budget, but neglecting the lack of patient benefit and the severe side effects that sometimes occurred. Leading this support was the Daily Mail, whose influence (measured by the product of number of stories and the papers circulation) was almost greater than that of the other newspapers combined. Results Press coverage was mainly very positive, arguing for the Cancer Drugs Fund’s extension to Scotland and Wales, and a bigger budget, but neglecting the lack of patient benefits and the severe side effects that sometimes occurred. Leading this support was the Daily Mail, whose influence (measured by the product of number of stories and the paper’s circulation) was almost greater than that of the other newspapers combined. Conclusions Although there was some critical analysis of the Cancer Drugs Fund, our analysis shows that most press coverage was largely positive and unrepresentative in comparison with the lack of overall benefits to patients and society. It is likely that it contributed to the Cancer Drugs Fund’s continuation despite mounting evidence of its ineffectiveness.
