Cancer control in Latin America and the Caribbean: recent advances and opportunities to move forward.

The increasing burden of cancer represents a substantial problem for Latin America and the Caribbean. Two Lancet Oncology Commissions in 2013 and 2015 highlighted potential interventions that could advance cancer care in the region by overcoming existing challenges. Areas requiring improvement included insufficient investment in cancer control, non-universal health coverage, fragmented health systems, inequitable concentration of cancer services, inadequate registries, delays in diagnosis or treatment initiation, and insufficient palliative services. Progress has been made in key areas but remains uneven across the region. An unforeseen challenge, the COVID-19 pandemic, strained all resources, and its negative effect on cancer control is expected to continue for years. In this Series paper, we summarise progress in several aspects of cancer control since 2015, and identify persistent barriers requiring commitment of additional resources to reduce the cancer burden in Latin America and the Caribbean.

Global cancer surgery: delivering safe, affordable, and timely cancer surgery.

Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

Choosing Wisely in oncology in Latin America: what SLACOM does not recommend in the care of cancer patients in Latin America: Ten essential recommendations to avoid harmful onclogy procedures in Latin America.

Choosing Wisely is an initiative by the American Board of Internal Medicine (ABIM) and ABIM Foundation to deter unnecessary medical treatments and procedures. Faced with the burden of modern technologies and treatments, it is crucial to identify practices lacking value in daily care. The Latin American and Caribbean Society (SLACOM), comprising cancer control experts, deems it vital to tailor this initiative for enhancing cancer care in the region. Through a modified DELPHI methodology involving two rounds of electronic questionnaires and a hybrid meeting to discuss key points of contention, ten essential recommendations were identified and prioritised to avoid harmful oncology procedures in our region. These consensus-based recommendations, contextualised for Latin America, have been compiled and shared to benefit patients. The Scientific Committee, consisting of prominent oncologists and health experts, collaborates remotely to drive this project forward.

[Current and future challenges of the use of precision medicine in cancer diagnosis and treatment in Brazil]. / Desafios atuais e futuros do uso da medicina de precisão no acesso ao diagnóstico e tratamento de câncer no Brasil.

This study seeks to culturally and ethically reflect on the current and future challenges of incorporating new biotechnologies to diagnose and treat cancer in Brazil and assess their impact on cancer control. To this end, this study begins by problematizing the literature on the subject and the results of a study that conducted a web survey with medical specialists from the Brazilian public and private sectors; the latter associated with the ten most representative cancer societies in the country, working in clinical practice, surgery, radiotherapy, pathology, and diagnosis. We discussed this study around three thematic axes: knowledge and expectations on the advent of new technologies to diagnose and treat cancer; structural and ethical considerations in the current and future use of new technologies; and possible scenarios associated with the use and application of new technologies to diagnose and treat cancer. We have raised some questions: will new technological paradigms benefit all Brazilian Unified National Health System (SUS) users, or will they be the privileges of the few? Will they reduce discrepancies regarding the distribution of technological services and resources and cancer diagnosis and treatment? How can different segments of society participate and influence this process? What scenarios can still compose this picture? Aiming to contribute to planning the future of cancer care in Brazil, this study proposes the development of future actions from five strategic dimensions: economy; science, innovation and technology; structure; culture; and regulation.

Social Distancing and Economic Crisis During COVID-19 Pandemic Reduced Cancer Control in Latin America and Will Result in Increased Late-Stage Diagnoses and Expense.

Since December 2019, the world has been mired in an infectious pandemic that has displaced other health priorities for 21st century populations. Concerned about this situation, Latin American experts on cancer decided to evaluate the impact of the pandemic on cancer control in the region. The analysis was based on information obtained from public sources and scientific publications and included the characteristics of the health care and cancer control prior to the pandemic, the COVID-19 pandemic and measures implemented by the governments of the region, and the regional impact of the pandemic on cancer control together with the costs of cancer care and possible impact of the pandemic on cancer expense. We compared 2019 and 2020 data corresponding to the period March 16-June 30 and found a significant reduction in the number of first-time visits to oncology services (variable depending on the country between -28% and -38%) and a corresponding reduction in pathology (between -6% and -50%), cancer surgery (between -28% and -70%), and chemotherapy (between -2% and -54%). Furthermore, a significant reduction in cancer screening tests was found (PAP smear test studies: between -46% and -100%, mammography: between -32% and -100%, and fecal occult blood test: -73%). If this situation becomes a trend, the health and economic impact will be compounded in the postpandemic period, with an overload of demand on health services to ensure diagnostic tests and consequent treatments. On the basis of this information, a set of prevention and mitigation measures to be immediately implemented and also actions to progressively strengthen health systems are proposed.

International collaborations in cancer control and the Third International Cancer Control Congress.

Over the past few decades, there has been growing support for the idea that cancer needs an interdisciplinary approach. Therefore, the international cancer community has developed several strategies as outlined in the WHO non-communicable diseases Action Plan (which includes cancer control) as the World Health Assembly and the UICC World Cancer Declaration, which both include primary prevention, early diagnosis, treatment, and palliative care. This paper highlights experiences/ideas in cancer control for international collaborations between low, middle, and high income countries, including collaborations between the European Union (EU) and African Union (AU) Member States, the Latin-American and Caribbean countries, and the Eastern Mediterranean countries. These proposals are presented within the context of the global vision on cancer control set forth by WHO in partnership with the International Union Against Cancer (UICC), in addition to issues that should be considered for collaborations at the global level: cancer survival (similar to the project CONCORD), cancer control for youth and adaptation of Clinical Practice Guidelines. Since cancer control is given lower priority on the health agenda of low and middle income countries and is less represented in global health efforts in those countries, EU and AU cancer stakeholders are working to put cancer control on the agenda of the EU-AU treaty for collaborations, and are proposing to consider palliative care, population-based cancer registration, and training and education focusing on primary prevention as core tools. A Community of Practice, such as the Third International Cancer Control Congress (ICCC-3), is an ideal place to share new proposals, learn from other experiences, and formulate new ideas. The aim of the ICCC-3 is to foster new international collaborations to promote cancer control actions in low and middle income countries. The development of supranational collaborations has been hindered by the fact that cancer control is not part of the objectives of the Millennium Development Goals (MGGs). As a consequence, less resources of development aids are allocated to control NCDs including cancer.

Evidence to wood biodeterioration of tropical species revealed by non-destructive techniques.

The wood biodeterioration process is one of the symptoms produced by biotic agents that affect the biomechanics of urban trees and reduce their useful life and environmental services. This process is mainly studied through methods that are time-consuming or destructive and provide little information regarding the degradation process at the cellular scale. Based on a non-destructive study of five tropical urban trees: Poincianella pluviosa (sibipiruna), Pterocarpus rhorii (aldrago), Rhamnidium elaeocarpum (saguaraji), Trichilia clausenii (Catiguá) and Lafoensia glyptocarpa (mirindiba rosa); the wood decaying zone, by xylophagous fungi, was analized. The trunk-wood samples containing the decaying zone were extracted with metal probes. Their microscopic anatomical structures were characterized and their microdensity and chemical composition analyzed by X-ray densitometry and X-ray fluorescence, respectively. Degraded cell wall fiber and vessels obstructed by mycelial mass were observed in wood decay zones. The presence of wood compartmentalized by the formation of extractive deposits was also observed, as a possible resistance mechanism varying among species. Likewise, phosphorus (P), calcium (Ca), calcium/manganese molar ratio and wood density increase were observed in barrier zones, while iron (Fe) was related to the decay zone. Altogether, the present study show for detailed evaluation of the wood biodeterioration process at the microscopic scale. The potential of non-destructive techniques for application in the physiological analysis of trees was also demonstrated.

Perspectives on Strengthening Cancer Research and Control in Latin America Through Partnerships and Diplomacy: Experience of the National Cancer Institute's Center for Global Health.

According to the Pan American Health Organization, noncommunicable diseases, including cancer, are the leading causes of preventable and premature death in the Americas. Governments and health care systems in Latin America face numerous challenges as a result of increasing morbidity and mortality from cancer. Multiple international organizations have recognized the need for collaborative action on and technical support for cancer research and control in Latin America. The Center for Global Health at the US National Cancer Institute (NCI-CGH) is one entity among many that are working in the region and has sought to develop a strategy for working in Latin America that draws on and expands the collaborative potential of engaged, skilled, and diverse partners. NCI-CGH has worked toward developing and implementing initiatives in collaboration with global partners that share the common objectives of building a global cancer research community and translating research results into evidence-informed policy and practice. Both objectives are complementary and synergistic and are additionally supported by an overarching strategic framework that is focused on partnerships and science diplomacy. This work highlights the overall strategy for NCI-CGH engagement in Latin America through partnerships and diplomacy, and highlights selected collaborative efforts that are aimed at improving cancer outcomes in the region.

Building capacity for sustainable research programmes for cancer in Africa.

Cancer research in Africa will have a pivotal role in cancer control planning in this continent. However, environments (such as those in academic or clinical settings) with limited research infrastructure (laboratories, biorespositories, databases) coupled with inadequate funding and other resources have hampered African scientists from carrying out rigorous research. In September 2012, over 100 scientists with expertise in cancer research in Africa met in London to discuss the challenges in performing high-quality research, and to formulate the next steps for building sustainable, comprehensive and multi-disciplinary programmes relevant to Africa. This was the first meeting among five major organizations: the African Organisation for Research and Training in Africa (AORTIC), the Africa Oxford Cancer Foundation (AfrOx), and the National Cancer Institutes (NCI) of Brazil, France and the USA. This article summarizes the discussions and recommendations of this meeting, including the next steps required to create sustainable and impactful research programmes that will enable evidenced-based cancer control approaches and planning at the local, regional and national levels.

SISMAMA--implementation of an information system for breast cancer early detection programs in Brazil.

As national health systems seek to apply breast cancer screening recommendations to an entire population of women (within target age ranges for which there is evidence that screening reduces mortality), the volume of screening tests and resulting diagnostic investigations arising from abnormal test results-and the cost associated with them-will grow dramatically. Population-based early detection (screening) programs will need information systems and management tools to help these programs. This report describes Brazil's highly decentralized health care system and then describes in greater detail how the development and implementation of an information system for Brazil's nationwide breast cancer early detection program was carried out with input from various stakeholders. Challenges encountered in the implementation are shared. Preliminary findings from the first 1.5 million mammograms are presented to demonstrate the kind of provocative management information such a system can yield in a relatively short period of time. The potential of such information systems for improving efficiency, efficacy and cost-effectiveness of early detection programs is emphasized.

Breast cancer management in middle-resource countries (MRCs): consensus statement from the Breast Health Global Initiative.

In middle resource countries (MRCs), cancer control programs are becoming a priority as the pattern of disease shifts from infectious diseases to non-communicable diseases such as breast cancer, the most common cancer among women in MRCs. The Middle Resource Scenarios Working Group of the BHGI 2010 Global Summit met to identify common issues and obstacles to breast cancer detection, diagnosis and treatment in MRCs. They concluded that breast cancer early detection programs continue to be important, should include clinical breast examination (CBE) with or without mammography, and should be coupled with active awareness programs. Mammographic screening is usually opportunistic and early detection programs are often hampered by logistical and financial problems, as well as socio-cultural barriers, despite improved public educational efforts. Although multidisciplinary services for treatment are available, geographical and economic limitations to these services can lead to an inequity in health care access. Without adequate health insurance coverage, limited personal finances can be a significant barrier to care for many patients. Despite the improved availability of services (surgery, pathology, radiology and radiotherapy), quality assurance programs remain a challenge. Better access to anticancer drugs is needed to improve outcomes, as are rehabilitation programs for survivors. Focused and sustained government health care financing in MRCs is needed to improve early detection and treatment of breast cancer.
