Low And Middle Income

Cancer is a growing global health issue, and many countries are ill-prepared to deal with their current cancer burden let alone the increased burden looming on the horizon. Growing and aging populations are projected to result in dramatic increases in cancer cases and cancer deaths particularly in low- and middle-income countries. It is imperative that planning begin now to deal not only with those cancers already occurring but also with the larger numbers expected in the future. Unfortunately, such planning is hampered, because the magnitude of the burden of cancer in many countries is poorly understood owing to lack of surveillance and monitoring systems for cancer risk factors and for the documentation of cancer incidence, survival and mortality. Moreover, the human resources needed to fight cancer effectively are often limited or lacking. Cancer diagnosis and cancer care services are also inadequate in low-and middle-income countries. Late-stage presentation of cancers is very common in these settings resulting in less potential for cure and more need for symptom management. Palliative care services are grossly inadequate in low- and middle-income countries, and many cancer patients die unnecessarily painful deaths. Many of the challenges faced by low- and middle-income countries have been at least partially addressed by higher income countries. Experiences from around the world are reviewed to highlight the issues and showcase some possible solutions.

Background and context: Cancer control requires knowledge of cancer incidence. Information on anatomic extent of disease (stage) at presentation significantly enhances incidence and mortality data in understanding the cancer burden. The most frequently used staging classification of cancer disease extent is the tumor, node, metastases (TNM). Population-based registries (PBCR) in low- and middle-income countries (LMIC) frequently have insufficient information to derive complete TNM data, either because of inability to perform the necessary evaluations or because of a lack of recorded information. Aim: To develop a simplified system of recording extent of disease to facilitate the collection of stage data by PBCR and enhance the utility of data to facilitate cancer control in LMICs. Strategy/Tactics: A working group with representatives from the UICC (Union for International Cancer Control), the IARC (International Agency for Cancer Research), IACR (International Association of Cancer Registries) and the NCI (National Cancer Institute) was formed and Essential TNM was developed. When the T, N, and M categories have not been recorded in the clinical records or if the complete data to determine the categories is unavailable, the cancer registrar can code extent of disease according to the Essential TNM scheme. Once a cancer registrar had identifies the presence of metastatic disease (M1) this is recorded and additional information is unnecessary to establish that stage of disease. If there is no metastatic disease the extent of nodal disease is recorded. In turn if there is no nodal disease the extent/size of the primary carcinoma is recorded. The extent of disease can be summarized in the following order: M, N and T. Program/Policy process: Diagrams and rules for combining Essential TNM elements into stage groups (I-IV) or to be expressed as “distant”, “regional” or “localized” if only the most limited data were available, were developed for breast, cervix, prostate and colon cancers and will be demonstrated. Once the schema were developed they were verified in Georgia (USA) and field tested in Ecuador, Malawi, Cote d'Ivoire and Zimbabwe. Outcomes: There was good agreement between the stage identified through Essential TNM and that within the Georgia State Registry. The field tests however identified three key issues: the underidentification of distant metastases, inaccurate the collection of lymph node data and improved training needs. In particular there was uncertainty in the identification of when lymph node involvement was considered to be distant metastatic or regional. In view of this, refinements to the schemas have been made to simplify the collection of nodal data. The schema have been updated to ensure compatibility with the 8th edition of TNM. Training programs are being developed and Essential TNM is being expanded. What was learned: Essential TNM can be used by LMIC PBCR to facilitate the collection of stage data. Further refinements and training are needed and are underway.

Abstract 28 Background: The global burden of cancer is growing in low- and middle-income countries where availability of specialists to treat cancer is acutely low. To detect cancer earlier, patients must be educated about their risk for cancer and be screened when appropriate. In response to a growing need for cancer education in primary health care, ASCO International created the Cancer Control in Primary Care course, which was piloted in 2015. The purpose of the program is to increase the knowledge of primary health workers so as to recognize signs and symptoms of cancer, increase their ability to talk with patients about their risk, and to know how and when to refer patients for additional screening or diagnostic testing. Methods: ASCO collects data from participants in two stages: an on-site evaluation and a follow-up survey 12 months after the workshop. The survey instruments include questions about practice changes, learning objectives, and demographic information. Results: Follow-up surveys have been conducted for four courses. Ninety-three percent of respondents have reported that they made practice changes after the course. In addition, 90% reported that communication with patients about their risk for cancer had increased, 76% reported that they are screening patients for cancer more than before, and 74% reported that they have worked with specialists to plan treatment for their patients with cancer. Conclusion: Results of the Cancer Control in Primary Care course are positive, and ASCO will continue to collaborate with society and institutional partners to train primary health workers around the world to raise awareness of cancer.

Low And Middle Income

Breakthroughs in our global fight against cancer have been achieved. However, this progress has been unequal. In low- and middle-income countries and for specific populations in high-income settings, many of these advancements are but an aspiration and hope for the future. This review will focus on health disparities in cancer within and across countries, drawing from examples in Kenya, Brazil, and the United States. Placed in context with these examples, the authors also draw basic recommendations from several initiatives and groups that are working on the issue of global cancer disparities, including the US Institute of Medicine, the Global Task Force on Expanded Access to Cancer Care and Control in Developing Countries, and the Union for International Cancer Control. From increasing initiatives in basic resources in low-income countries to rapid learning systems in high-income countries, the authors argue that beyond ethics and equity issues, it makes economic sense to invest in global cancer control, especially in low- and middle-income countries.

Low And Middle Income

The rising prevalence of noncommunicable diseases globally, with a strikingly disproportionate increase in prevalence and related mortality in low- and middle-income countries (LMICs), is a major threat to sustainable development. The epidemiologic trend of cancers in LMICs is of particular concern. Despite a lower incidence of cancer in LMICs compared with high-income countries, total cancer-related mortality is significantly higher in LMICs, especially in people younger than 65 years of age. The enormous economic impact of premature mortality and lost productive life years highlights the critical importance of galvanizing cancer prevention and management to achieve sustainable development. The rising burden of cancer in LMICs stresses an already weak health care and economic infrastructure and poses unique challenges. Although the WHO acknowledges that the effective management of cancer relies on early detection, accurate diagnosis, and access to appropriate multimodal therapy, the placement of priority on early detection cannot be assumed to be effective in LMICs, where limited downstream resources may be overwhelmed by the inevitable increases in number of diagnoses. This review discusses several factors and considerations that may compromise the success of cancer control programs in LMICs, particularly if the focus is only on early detection through screening and surveillance. It is intended to guide optimal implementation of cancer control programs by accentuating challenges common in LMICs and by emphasizing the importance of cancer prevention where relevant so that communities and stakeholders can work together to devise optimal means of combatting the growing burden of cancer.
