RESUMEN
There is a gap in the understanding of the barriers to cancer screening participation and complying with downstream management in the Community of Latin American and Caribbean states (CELAC). Our study aimed to assess barriers across the cancer screening pathway from the health system perspective, and interventions in place to improve screening in CELAC. A standardized tool was used to collect information on the barriers across the screening pathway through engagement with the health authorities of 27 member states of CELAC. Barriers were organized in a framework adapted from the Tanahashi conceptual model and consisted of the following dimensions: availability of services, access (covering accessibility and affordability), acceptability, user-provider interaction, and effectiveness of services (which includes governance, protocols and guidelines, information system, and quality assurance). The tool also collected information of interventions in place, categorized in user-directed interventions to increase demand, user-directed interventions to increase access, provider-directed interventions, and policy and system-level interventions. All countries prioritized barriers related to the information systems, such as the population register not being accurate or complete (N = 19; 70.4%). All countries implemented some kind of intervention to improve cancer screening, group education being the most reported (N = 23; 85.2%). Training on screening delivery was the most referred provider-directed intervention (N = 19; 70.4%). The study has identified several barriers to the implementation of cancer screening in the region and interventions in place to overcome some of the barriers. Further analysis is required to evaluate the effectiveness of these interventions in achieving their objectives.

Isothermal nucleic acid amplification methods have many advantages for use at the point of care. However, there is a lack of multiplexed isothermal amplification tests to detect multiple targets in a single reaction, which would be valuable for many diseases, such as infection with high-risk human papillomavirus (hrHPV). In this study, we developed a multiplexed loop-mediated isothermal amplification (LAMP) reaction to detect the three most common hrHPV types that cause cervical cancer (HPV16, HPV18, and HPV45) and a cellular control for sample adequacy. First, we characterized the assay limit of detection (LOD) in a real-time reaction with fluorescence readout; after 30 min of amplification the LOD was 100, 10, and 10 copies/reaction of HPV16, HPV18, and HPV45, respectively, and 0.1 ng/reaction of human genomic DNA (gDNA). Next, we implemented the assay on lateral flow strips, and the LOD was maintained for HPV16 and HPV18, but increased to 100 copies/reaction for HPV45 and to 1 ng/reaction for gDNA. Lastly, we used the LAMP test to evaluate total nucleic acid extracted from 38 clinical samples; compared to qPCR, the LAMP test had 89% sensitivity and 95% specificity. When integrated with sample preparation, this multiplexed LAMP assay could be useful for point-of-care testing.

BACKGROUND: Training health care providers to administer visual inspection after application of acetic acid (VIA) is paramount in improving cervical cancer screening services for women in low- and middle-income countries. The objective of this systematic review was to create a framework of essential VIA training components and provide illustrating examples of how VIA training programs can be carried out in different clinical settings. METHODS: A systematic review of PubMed, Embase, and Web of Science (from 2006 to 2021) was undertaken. Our inclusion criteria comprised articles reporting on implemented cervical cancer screening programs using VIA in a screen-and-treat approach. Trained health care providers with any level of health education were included, and the outcome of interest was the reporting of training components. Data were extracted by two reviewers, and a narrative synthesis of the training programs was performed. We developed a framework of seven essential training components and applied it to assess how training courses were conducted in different settings. RESULTS: 13 primary studies were eligible for inclusion, including 2,722 trained health care providers and 342,889 screened women. Most training courses lasted 5-7 days and included theoretical education, practical skill development, and competence assessment. It was unclear how visual aids and training in client counselling and quality assessment were integrated in the training courses. After the training course, nearly all the VIA training programs made provisions for on-job training at the providers' own clinical settings through supervision, feedback, and refresher training. CONCLUSIONS: This study demonstrates the feasibility of implementing international training recommendations for cervical cancer screening in real-world settings and provides valuable examples of training program implementation across various clinical settings. The diverse reporting practices of quality indicators in different studies hinder the establishment of direct links between these data and training program effectiveness. To enhance future reporting, authors should emphasize specific training components, delivery methods, and contextual factors. Standardized reporting of quality indicators for effective evaluation of VIA training programs is recommended, fostering comparability, facilitating research, and enhancing reporting quality in this field.

Storytelling can enhance stakeholder engagement and support the implementation of the World Health Organization and Pan American Health Organization's (PAHO) Global Initiative for Childhood Cancer, which aims to improve care globally for children with cancer. The Initiative aligns with the United Nations Sustainable Development Goals, addressing health, education, inequalities and international collaboration. This report describes the design and implementation of a workshop that used storytelling through film to encourage stakeholders in national cancer control plans to engage with the Initiative in its focal countries in Central America, the Dominican Republic and Haiti. A six-step process was used to develop the virtual workshop hosted by PAHO: (i) define the audience; (ii) define the goals of storytelling; (iii) build an appropriate storyline, including choosing a platform and content, and addressing group dynamics and the length of the film; (iv) guide the workshop's design and implementation with current theoretical frameworks, including the Socioecological Model of Health and the Theory of Change; (v) design interactive group exercises; and (vi) disseminate workshop results. The skills-building component of the day-long workshop included 80 representatives from eight countries in the Region of the Americas, with participants representing pediatric oncology, hospital administration, ministries of health, nonprofit foundations, the scientific community and public health organizations. Outputs from the workshop included (i) a summary report, (ii) an empathy word cloud with live reactions from participants, (iii) qualitative responses (i.e. quotes from participants), (iv) stakeholders' analyses and (v) a prioritization matrix for country-level strategic activities that could be undertaken to strengthen health systems when caring for children with cancer. The workshop used storytelling through film to try to reduce health inequalities and have a regional impact. Combining art, public health and medicine, the workshop created positive change by sharing real-life experiences. Commitment was fostered among stakeholders through their engagement with the workshop, which aimed to increase their awareness of the need and advocacy to improve health systems and enhance access to health care for this vulnerable population.
La narración de historias puede mejorar la participación de las partes interesadas y brindar apoyo para la aplicación de la Iniciativa Mundial contra el Cáncer Infantil de la Organización Mundial de la Salud y la Organización Panamericana de la Salud (OPS), dirigida a mejorar la atención a los pacientes pediátricos con cáncer en todo el mundo. La Iniciativa se enmarca en el contexto de los Objetivos de Desarrollo Sostenible de las Naciones Unidas, que abordan la salud, la educación, las desigualdades y la colaboración internacional. En este informe se describe el diseño y la realización de un taller en el que se utilizó la narración de historias mediante películas para animar a las partes interesadas de los planes nacionales de control del cáncer a colaborar con la iniciativa en los países del proyecto en Centroamérica, Haití y República Dominicana. Para preparar el taller virtual organizado por la OPS, se utilizó un proceso de seis pasos: i) definir el público destinatario; ii) definir los objetivos de la narración; iii) confeccionar una estructura argumental adecuada, incluida la elección del tipo de plataforma y el contenido, y tener en cuenta tanto las dinámicas de grupo como la duración de la película; iv) basar el diseño y la realización del taller en marcos teóricos actuales, incluidos el modelo socioecológico de la salud y la teoría del cambio; v) diseñar ejercicios grupales interactivos; y vi) difundir los resultados del taller. En el componente de adquisición de competencias del taller, de un día de duración, participaron 80 representantes de ocho países de la Región de las Américas, pertenecientes a los ámbitos de la oncología pediátrica, la gestión hospitalaria, los ministerios de salud, fundaciones sin ánimo de lucro, la comunidad científica y organizaciones de salud pública. Los resultados del taller incluyeron i) un resumen del informe, ii) una nube de palabras relacionadas con la empatía que recogía las reacciones en tiempo real de las personas participantes, iii) respuestas cualitativas (es decir, citas de lo expresado por las personas participantes), iv) análisis de las partes interesadas y v) una matriz de priorización de las actividades estratégicas a nivel de país que se podrían llevar a cabo para fortalecer los sistemas de salud a la hora de prestar atención de salud a los pacientes pediátricos con cáncer. En el taller se recurrió a la narración de historias en forma de película para tratar de reducir las inequidades en materia de salud y lograr un impacto a nivel regional. La combinación de arte, salud pública y medicina propició la generación de cambios favorables mediante el intercambio de experiencias de la vida real. Se fomentó el compromiso de las partes interesadas a través de su participación en el taller, lo cual tenía como objetivo aumentar su concientización sobre la importancia de la promoción y la necesidad de mejorar tanto los sistemas de salud como el acceso a la atención de salud para esta población vulnerable.

A oficina usou histórias narradas por meio de filmes para tentar reduzir as desigualdades de saúde e alcançar um impacto regional. Combinando arte, saúde pública e medicina, a oficina criou uma mudança positiva por meio do compartilhamento de experiências da vida real. A participação na oficina, cujo objetivo era aumentar a conscientização sobre a necessidade de pleitear melhorias nos sistemas de saúde e no acesso à atenção à saúde para essa população vulnerável, fomentou o compromisso entre as partes interessadas.
RESUMEN
Working with PAHO/WHO to prioritize childhood cancer in the context of systems strengthening is central to St. Jude Children's Research Hospital (SJCRH)'s role as WHO Collaborating Centre for Childhood Cancer. This manuscript focuses on how SJCRH and PAHO/WHO have partnered to apply C5 (Country Collaboration for Childhood Cancer Control) to define and implement priority actions regionally, strengthening Ministry programs for childhood cancer, while implementing the Global Initiative for Childhood Cancer since 2018. Using C5, a tool developed by SJCRH, PAHO/WHO and SJCRH co-hosted regional/national workshops engaging authorities, clinicians and other stakeholders across 10 countries to map health systems needs and prioritize strategic activities (spanning Central America, Dominican Republic, Haiti, Brazil and Uruguay). SJCRH provided English/Spanish/Portuguese C5 versions/templates for analysis/prioritization exercises, and worked with PAHO/WHO and country teams to implement C5, analyze findings, and develop outputs. In an eight-country regional workshop, countries defined priorities within national/regional initiatives and ranked their value and political will, incorporating country-specific surveys and stakeholder dialogues. Each country prioritized one strategic activity for 2022-2023, exchanged insights via storytelling, and disseminated and applied results to inform country-specific and regional action plans. National workshops analyses have been incorporated into cancer control planning activities and collaborative work regionally. Implementation success factors include engaging actors beyond the clinic, enabling flexibility, and focusing on co-design with stakeholders. Joint implementation of C5 catalyzed prioritization and accelerated strategic activities to improve policies, capacity, and quality of care for children in the Americas, supporting Ministries to integrate childhood cancer interventions as part of systems strengthening.
La colaboración con la OPS/OMS para priorizar el cáncer infantil en el contexto del fortalecimiento de los sistemas es fundamental para la labor del St. Jude Children's Research Hospital (SJCRH) como centro colaborador de la OMS contra el cáncer infantil. Este artículo se centra en la alianza entre el SJCRH y la OPS/OMS en la aplicación de la herramienta C5 (colaboración nacional para el control del cáncer infantil) para definir y ejecutar medidas prioritarias a nivel regional, fortalecer los programas contra el cáncer infantil del ministerio y poner en marcha la Iniciativa Mundial contra el Cáncer Infantil desde el 2018. Con C5, una herramienta elaborada por el SJCRH, la OPS/OMS y este hospital organizaron conjuntamente talleres regionales y nacionales con autoridades, personal médico y otras partes interesadas en diez países para determinar cuáles son las necesidades de los sistemas de salud y priorizar las actividades estratégicas (en América Central, República Dominicana, Haití, Brasil y Uruguay). El SJCRH proporcionó versiones y plantillas de C5 en inglés, español y portugués para actividades de análisis y priorización y trabajó con la OPS/OMS y los equipos de país para ejecutar la herramienta C5, analizar los resultados y elaborar productos. En un taller regional de ocho países, se definieron las prioridades en las iniciativas regionales y nacionales, se clasificó su valor y la voluntad política y se incorporaron encuestas específicas para cada país y diálogos con las partes interesadas. Cada país priorizó una actividad estratégica para el período 2022-2023, intercambió ideas por medio de narrativas, y difundió y aplicó los resultados para fundamentar planes de acción tanto regionales como específicos para el país. Los análisis de los talleres nacionales se han incorporado a las actividades de planificación del control del cáncer y al trabajo colaborativo a nivel regional. Entre los factores de éxito de la ejecución se encuentra involucrar a los agentes más allá de lo clínico, permitir que haya flexibilidad y centrarse en un diseño elaborado en colaboración con las partes interesadas. La ejecución conjunta de la herramienta C5 catalizó la priorización y aceleró las actividades estratégicas para mejorar las políticas, la capacidad y la calidad de la atención infantil en la Región de las Américas y brindó apoyo a los ministerios para integrar las intervenciones contra el cáncer infantil en el fortalecimiento de los sistemas.
A colaboração com a OPAS/OMS para priorizar o câncer infantil no contexto do fortalecimento dos sistemas é fundamental para o papel do St. Jude Children's Research Hospital (SJCRH) como Centro Colaborador da OMS para o Câncer Infantil. Este artigo mostra como o SJCRH e a OPAS/OMS se associaram para aplicar a ferramenta C5 (Colaboração Nacional para Controle do Câncer Infantil), com o propósito de definir e implementar ações prioritárias regionalmente, fortalecendo programas ministeriais para o câncer na infância, durante a implementação da Iniciativa Global para o Câncer Infantil desde 2018. Com auxílio da C5, uma ferramenta desenvolvida pelo SJCRH, a OPAS/OMS e o SJCRH organizaram conjuntamente oficinas regionais/nacionais com a participação de autoridades, profissionais de saúde e outras partes interessadas em 10 países, com a finalidade de mapear as necessidades dos sistemas de saúde e priorizar atividades estratégicas (abrangendo América Central, República Dominicana, Haiti, Brasil e Uruguai). O SJCRH forneceu versões/modelos da C5 em inglês, espanhol e português para exercícios de análise/priorização e colaborou com a OPAS/OMS e as equipes dos países para implementar a C5, analisar resultados e desenvolver produtos. Em uma oficina regional com oito países, foram definidas as prioridades das iniciativas nacionais/regionais e classificados seu valor e vontade política, incorporando levantamentos nacionais e diálogos entre as partes interessadas. Cada país priorizou uma atividade estratégica para 2022-2023, trocou conhecimentos por meio da narração de histórias e disseminou e aplicou os resultados para informar planos de ação nacionais e regionais. As análises das oficinas nacionais foram incorporadas às atividades de planejamento para controle do câncer e ao trabalho conjunto no âmbito regional. Entre os fatores de êxito da implementação estão o engajamento de agentes de fora do segmento da saúde, a oferta de flexibilidade e a ênfase no planejamento conjunto com as partes interessadas. A implementação conjunta da C5 catalisou a priorização e acelerou atividades estratégicas para aprimorar as políticas, a capacidade e a qualidade da atenção às crianças nas Américas, apoiando os ministérios na integração das intervenções contra o câncer infantil como parte do fortalecimento dos sistemas.
RESUMEN
This article aims to describe the activities conducted by the National Childhood Cancer Plan Working Group to support the development of national childhood cancer plans in Latin America and the Caribbean in the period 2019-2022, and to present the stage of plan development. The Working Group activities were supported by the Pan American Health Organization and St. Jude Children's Research Hospital, which is the World Health Organization (WHO) Collaborating Centre for Childhood Cancer. Year after year, the workshops and activities developed with the Working Group mobilized key stakeholders: pediatric oncologists, representatives of the Ministry of Health, foundations supporting childhood cancer initiatives, and hospital administrators. As of February 2023, one regional framework is in place, approved by the Council of Ministries of Health of Central America and the Dominican Republic, nine countries are currently implementing national plans or laws that include childhood cancer, and ten countries are writing new plans. The WHO three-step framework helped to guide the Working Group activities. All plans were supported by a situational analysis, which highlighted the importance of having systematized data for evidence-based policies. To increase implementation success, an accompanying budget and timeline help to ensure the adequate implementation of the interventions. More than anything, committed stakeholders remain the most fundamental element to successfully write and approve a national childhood cancer plan. This is an opportunity to share these countries' experience so the strategy can be adapted to support other countries developing a childhood cancer plan and extended to other public health areas.
En este artículo se describen las actividades realizadas por el grupo de trabajo del plan nacional contra el cáncer infantil dirigidas a brindar apoyo para la formulación de planes nacionales contra el cáncer infantil en América Latina y el Caribe en el período 2019-2022, así como la presentación de la etapa de formulación de los planes. Las actividades del Grupo de Trabajo contaron con el apoyo de la Organización Panamericana de la Salud y el St. Jude Children's Research Hospital, que es el centro colaborador de la Organización Mundial de la Salud (OMS) contra el cáncer infantil. Año tras año, los talleres y actividades llevados a cabo con el grupo de trabajo han logrado convocar a las principales partes interesadas: especialistas en oncología pediátrica, representantes del Ministerio de Salud, fundaciones que apoyan iniciativas contra el cáncer infantil y gerentes de los hospitales. Desde febrero del 2023, existe un marco regional, aprobado por el Consejo de Ministerios de Salud de Centroamérica y República Dominicana; nueve países ya están aplicando planes o leyes nacionales en los que se incluye el cáncer infantil, y diez países están redactando nuevos planes. Para orientar las actividades del Grupo de Trabajo, se recurrió al marco en tres pasos de la OMS. Todos los planes se sustentaron en un análisis de situación lo que subraya la importancia de contar con datos sistematizados para que las políticas puedan estar basadas en evidencias. Asimismo, si se pretende aumentar el éxito de la aplicación, sería conveniente contar con un presupuesto y un cronograma que aseguren la aplicación adecuada de las intervenciones. Las partes interesadas implicadas siguen siendo, ante todo, el componente más trascendente en la redacción y aprobación exitosa de un plan nacional contra el cáncer infantil. Esta es una oportunidad para transmitir la experiencia de estos países, con el fin de que la estrategia pueda adaptarse para brindar apoyo a otros países que estén elaborando un plan contra el cáncer infantil y que puede hacerse extensiva a otros ámbitos de la salud pública.
Este artigo visa a descrever as atividades realizadas pelo Grupo de Trabalho para Planos Nacionais de Combate ao Câncer infantil a fim de prestar apoio ao desenvolvimento de planos nacionais de combate ao câncer infantil na América Latina e no Caribe no período de 2019 a 2022 e apresentar a atual fase de desenvolvimento dos planos. As atividades do Grupo de Trabalho receberam apoio da Organização Pan-Americana da Saúde e do St. Jude Children's Research Hospital, o Centro Colaborador em Câncer infantil da Organização Mundial da Saúde (OMS). Ano após ano, as oficinas e atividades desenvolvidas com o Grupo de Trabalho mobilizaram as principais partes interessadas: oncologistas pediátricos, representantes dos ministérios da saúde, fundações que apoiam iniciativas de combate ao câncer infantil e administradores de hospitais. Até fevereiro de 2023, havia uma estrutura regional em vigor aprovada pelo Conselho de Ministros da Saúde da América Central e da República Dominicana, nove países estavam implementando planos ou leis nacionais que incluíam o câncer infantil e dez países estavam elaborando novos planos. A estrutura de três etapas da OMS ajudou a orientar as atividades do Grupo de Trabalho. Todos os planos estavam embasados em uma análise situacional, o que destacou a importância de dispor de dados sistematizados para políticas baseadas em evidências. Para aumentar o sucesso da implementação, um orçamento e um cronograma correspondentes ajudam a garantir a implementação adequada das intervenções. Acima de tudo, o compromisso das partes interessadas continua sendo o elemento mais fundamental para elaborar e aprovar com sucesso um plano nacional de combate ao câncer infantil. Esta é uma oportunidade de compartilhar a experiência desses países para que a estratégia possa ser adaptada a fim de apoiar outros países na elaboração de um plano de combate ao câncer infantil e possa ser estendida a outras áreas de saúde pública.
RESUMEN
Objective: To describe the development of educational materials for parents and other caregivers of children with cancer, which utilized a culturally sensitive approach to reduce acceptance barriers to palliative care (PC). Methods: The Pan American Health Organization (PAHO), St. Jude Children's Research Hospital, and partners in Latin America and the Caribbean collaborated in a three-phase project, beginning with a needs assessment survey of caregivers of children with cancer in Peru. Based on this finding, an interdisciplinary team of pediatric PC experts developed educational content that was designed and validated by an international committee of PC and communication experts. Results: The collaboration resulted in the development of an eight-module series that introduces caregivers to key concepts of pediatric PC, including management of pain, quality of life, and end of life care. The series was designed to reduce caregiver stigma associated with PC through culturally sensitive education that addresses the low levels of health literacy among caregivers in Latin America and the Caribbean. In the 15 months since the launch, these modules have been distributed throughout Latin America and were downloaded 2 825 times. Conclusions: Educational materials and anticipatory guidance of PC were considered to be a priority for parents and other caregivers of children with cancer throughout Latin America. The materials developed through this project have been widely utilized and are available through the PAHO website and the Together by St. Jude™ online resource.
RESUMEN
This article describes progress in tackling noncommunicable diseases (NCDs) in the Americas since the Pan American Health Organization (PAHO) started its NCD program 25 years ago. Changes in the epidemiology of NCDs, NCD policies, health service capacity, and surveillance are discussed. PAHO's NCD program is guided by regional plans of action on specific NCDs and risk factors, as well as a comprehensive NCD plan. Its work involves implementing evidence-based World Health Organization technical packages on NCDs and their risk factors with the aim of achieving the Sustainable Development Goal target of a one third reduction in premature mortality caused by NCDs by 2030. Important advances have been made in the past 25 years in implementation of: policies on NCD risk factors; interventions to improve NCD diagnosis and treatment; and NCD surveillance. Premature mortality from NCDs decreased by 1.7% a year between 2000 and 2011 and 0.77% a year between 2011 and 2019. However, policies on risk factor prevention and health promotion need to be strengthened to ensure more countries are on track to achieving the NCD-related health goals of the Sustainable Development Goals by 2030. Actions are recommended for governments to raise the priority of NCDs by: making NCDs a core pillar of primary care services, using revenues from health taxes to invest more in NCD prevention and control; and implementing policies, laws, and regulations to reduce the demand for and availability of tobacco, alcohol, and ultra-processed food products.
En este artículo se describe el progreso en la lucha contra las enfermedades no transmisibles (ENT) en la Región de las Américas desde que la Organización Panamericana de la Salud (OPS) iniciara su programa contra las ENT hace 25 años. Se abordan los cambios en las características epidemiológicas, las políticas, la capacidad de los servicios de salud y la vigilancia de estas enfermedades. Este programa de la OPS se rige por planes regionales de acción sobre enfermedades y factores de riesgo específicos, así como por un plan integral de ENT. Su labor consiste en poner en práctica paquetes técnicos de la Organización Mundial de la Salud basados en la evidencia sobre las ENT y sus factores de riesgo con el objetivo de alcanzar la meta de los Objetivos de Desarrollo Sostenible (ODS) de reducir en un tercio la mortalidad prematura causada por las ENT para el 2030. En los últimos 25 años se han logrado importantes avances en la ejecución de políticas sobre los factores de riesgo de estas enfermedades, en las intervenciones para mejorar su diagnóstico y tratamiento, y en la vigilancia. La mortalidad prematura por ENT disminuyó 1,7% anual entre el 2000 y el 2011 y 0,77% anual entre los años 2011 y 2019. Sin embargo, es necesario fortalecer las políticas de prevención de factores de riesgo y promoción de la salud para garantizar que más países estén bien encaminados para lograr las metas de salud de los ODS relacionadas con las ENT para el 2030. Se recomiendan medidas para que los gobiernos prioricen más las ENT y las conviertan en un pilar central de los servicios de atención primaria, al usar los ingresos generados por los impuestos en el sector de la salud para incrementar las inversiones en la prevención y control de las ENT, y ejecutar políticas, leyes y regulaciones para reducir la demanda y la disponibilidad de tabaco, alcohol y alimentos ultraprocesados.
Este artigo descreve o progresso no combate às doenças não transmissíveis (DNTs) nas Américas desde que a Organização Pan-Americana da Saúde (OPAS) iniciou seu programa para essas doenças há 25 anos. Discute-se como evoluíram a epidemiologia das DNTs, as políticas contra essas doenças, a capacidade dos serviços de saúde e a vigilância. O programa da OPAS para as DNTs é orientado por planos de ação regionais sobre DNTs específicas e fatores de risco, bem como por um plano integral contra essas doenças. O trabalho envolve a implementação de pacotes técnicos da Organização Mundial da Saúde baseados em evidências sobre as DNTs e seus fatores de risco, no intuito de alcançar a meta do Objetivo de Desenvolvimento Sustentável de reduzir em um terço a mortalidade prematura causada pelas DNTs até 2030. Avanços importantes foram obtidos nos últimos 25 anos na implementação de políticas sobre fatores de risco das DNTs, intervenções para melhorar o diagnóstico e o tratamento das DNTs, e vigilância das DNTs. A mortalidade prematura causada pelas DNTs diminuiu 1,7% ao ano entre 2000 e 2011 e 0,77% ao ano entre 2011 e 2019. Contudo, as políticas sobre a prevenção dos fatores de risco e a promoção da saúde precisam ser fortalecidas para que mais países estejam no rumo certo para alcançar as metas de saúde relacionadas a essas doenças, no âmbito dos Objetivos de Desenvolvimento Sustentável até 2030. São recomendadas medidas para que os governos elevem a prioridade das DNTs ao torná-las um pilar central dos serviços de atenção primária, usando a receita dos tributos saudáveis para investir mais na prevenção e no controle das DNTs, e ao implementar políticas, leis e regulamentos para reduzir a demanda e a disponibilidade de álcool, tabaco e produtos alimentícios ultraprocessados.
RESUMEN
This report describes the status of childhood cancer control initiatives in Latin America and the Caribbean (LAC). Progress between 2017 and 2023 is measured using the outcome indicators from the Pan American Health Organization (PAHO) childhood cancer logic model aligned with the World Health Organization Global Initiative for Childhood Cancer (GICC). This report also describes the advances, barriers, and facilitators for the implementation of the GICC at the Regional level. Methods used in this report encompassed a comprehensive approach, incorporating a literature review, interviews, surveys, and a Delphi study developed by the technical team of the PAHO Non-Communicable Diseases and Mental Health Department and by the GICC LAC working group. Since 2017, there has been a substantial increase in the number of countries that have included childhood cancer in their national regulations. Currently, 21 LAC countries are involved in the GICC implementation, activities, and dialogues. However, the objectives for 2030 will only be achieved if Member States overcome the barriers to accelerating the pace of initiative implementation. There is an urgent need to increase the efforts in childhood cancer control in LAC, especially regarding the prioritization of timely detection, essential diagnostics, access to cancer treatment, palliative care, and close follow-up of children and adolescents with cancer.
En este artículo se describe la situación de las iniciativas para el control del cáncer infantil en América Latina y el Caribe. Para medir los progresos entre el 2017 y el 2023, se utilizan los indicadores de resultados del modelo lógico del cáncer infantil de la Organización Panamericana de la Salud (OPS) que es coherente con la Iniciativa Mundial contra el Cáncer Infantil de la Organización Mundial de la Salud. También se describen los avances, los obstáculos y los elementos que han facilitado la aplicación de esa iniciativa en la Región Los métodos utilizados en este trabajo incluyeron un enfoque integral que incorporó una revisión bibliográfica, entrevistas, encuestas y un estudio de tipo Delfos llevado a cabo por el equipo técnico del Departamento de Enfermedades No Transmisibles y Salud Mental de la OPS y por el grupo de trabajo de América Latina y el Caribe de la Iniciativa Mundial contra el Cáncer Infantil de la Organización Mundial de la Salud.Desde el 2017 ha habido un incremento considerable en el número de países que incorporan el cáncer infantil en sus regulaciones nacionales. En la actualidad, 21 países de América Latina y el Caribe participan en la puesta en práctica, las actividades y las deliberaciones de la Iniciativa Mundial contra el Cáncer Infantil de la Organización Mundial de la Salud. No obstante, los objetivos para el 2030 solo podrán alcanzarse si los Estados Miembros son capaces de superar los obstáculos que dificultan la aceleración del ritmo de aplicación de esta iniciativa. Existe una necesidad urgente de aumentar las actividades dirigidas al control del cáncer infantil en América Latina y el Caribe, en especial en lo que respecta a priorizar la detección temprana, los medios de diagnóstico esenciales, el acceso a los tratamientos oncológicos, los cuidados paliativos y el seguimiento estricto de la población infantil y adolescente con cáncer.
Este relatório descreve a situação das iniciativas de controle do câncer infantil na Região da América Latina e do Caribe (ALC). O progresso alcançado entre 2017 e 2023 foi medido usando os indicadores de resultados intermediários do modelo lógico de câncer infantil da Organização Pan-Americana da Saúde (OPAS), em linha com a Iniciativa Global para o Câncer Infantil (GICC) da Organização Mundial da Saúde. O relatório também descreve os avanços, as barreiras e os facilitadores para a implementação da iniciativa em nível regional. Os métodos utilizados neste relatório aplicaram uma abordagem abrangente que incluiu revisão da literatura, entrevistas, levantamentos e um estudo Delphi desenvolvido pela equipe técnica do Departamento de Doenças Não Transmissíveis e Saúde Mental da OPAS e pelo grupo de trabalho da GICC para a ALC.Desde 2017, houve um aumento significativo no número de países que passaram a incluir o câncer infantil em regulamentações nacionais. Atualmente, 21 países da América Latina e do Caribe estão envolvidos na implementação da GICC, bem como em atividades e diálogos relacionados. No entanto, os objetivos para 2030 só serão alcançados se os Estados Membros superarem as barreiras ao aceleramento do ritmo de implementação da iniciativa. Existe uma necessidade urgente de intensificar os esforços de controle do câncer infantil na ALC, especialmente no tocante à priorização da detecção em tempo hábil, diagnósticos essenciais, acesso a tratamentos oncológicos, cuidados paliativos e acompanhamento cuidadoso de crianças e adolescentes com câncer.
RESUMEN
We describe the outcomes of The Extension for Community Healthcare Outcomes-Elimination of Cervical Cancer in The Americas (ECHO-ELA) program, which was developed as a tri-lateral cooperation between Pan American Health Organization (PAHO), the U.S. National Cancer Institute (NCI) and The University of Texas MD Anderson Cancer Center (MD Anderson). The program's purpose is to disseminate strategies for cervical cancer prevention and is structured around the three pillars of the World Health Organization's (WHO) Cervical Cancer Elimination Strategy and the associated 90-70-90 target goals. The target audience includes health authorities from Latin American and Caribbean countries, as well as PAHO's non-communicable disease Focal Points in country offices as well as clinical and public health collaborators. The virtual sessions are held in Spanish for 1.5 hours every month using the ECHO® format. From May 2020 to June 2021, 14 ECHO sessions were held with an average of 74 participants per session (range: 46 - 142). We conducted two anonymous surveys (baseline and follow up) and two focus groups. Respondents stated that the topics they learned the most about included the state of HPV vaccination in the region and strategies for implementing HPV vaccination. Identified needs included support between ECHO sessions and country-specific technical assistance. The ECHO-ELA program provides a forum for increased collaboration between countries in Latin America/Caribbean and the dissemination of best-practice strategies to reach the WHO Cervical Cancer Elimination target goals.

RESUMEN
Objective: To report the progress in Peru, since June 2019, in the implementation of the World Health Organization Global Initiative for Childhood Cancer using the CureAll framework, which can be replicated in low- and middle-income countries. Methods: A mixed method was used of participatory and documentary evaluation. The participatory evaluation included stakeholders from various government institutions, nonprofit organizations, and international partners. The documentary aspect consisted of a review of data on the regulatory environment, national projects, and interventions implemented. The Ministry of Health engaged more than 150 participants to form working committees, which have developed policy and regulatory documents to strengthen care services. Results: Achievements include a decrease in the national treatment abandonment rate from 18.6% to 8.5%, the approval of the Childhood Cancer Law, improvements in the management of patients with febrile neutropenia, and a reduction in rates of events of clinical deterioration and mortality of hospitalized patients. The Cure All implementation framework allows local teams to implement specific strategies and monitor early outcomes in pediatric oncology. Conclusions: The results obtained reflect the teamwork, the leadership of the authorities, the technical support of professionals, and the support of involved organizations. Further actions will be needed to guarantee sustainability, and monitoring tools are needed to assure success in the planned activities.
RESUMEN
The Global Initiative for Childhood Cancer (GICC) aims to increase the cure rate for children with cancer globally by improving healthcare access and quality. The Pan American Health Organization (PAHO), St. Jude Children's Research Hospital (St. Jude), and collaborators have joined efforts to improve outcomes of children with cancer in Latin America and the Caribbean (LAC) using the CureAll framework. In this article, we describe the process of developing regional resources aimed at accelerating the GICC implementation in LAC. In March 2021, PAHO formed regional working groups to develop core projects aligned with CureAll pillars and enablers. Seven working groups emerged from regional dialogues: early detection, nursing, psychosocial, nutrition, supportive care, treatment abandonment, and palliative care. PAHO arranged regular online meetings under the mentorship and support of St. Jude regional/transversal programs and international mentors. Between April and December 2021, 202 multidisciplinary experts attended 43 online meetings to promote the dialogue between stakeholders to improve childhood cancer outcomes. Fourteen technical outputs were produced: four regional snapshots, four technical documents, two virtual courses, one set of epidemiological country profiles, one educational content series for parents/caregivers, and two communication campaigns. The ongoing dialogue and commitment of PAHO, St. Jude, LAC working committees, and international collaborators are essential foundations to successfully accelerate GICC implementation. This is achievable through the development of materials of regional and global relevance. Further research and evaluation are needed to determine the impact of these strategies and resources on childhood cancer outcomes in LAC and other regions.

La Organización Panamericana de la Salud (OPS), el St. Jude Children's Research Hospital y los colaboradores han aunado esfuerzos para mejorar los resultados en la población infantil con cáncer en América Latina y el Caribe valiéndose del marco CureAll. En este artículo describimos el proceso de elaboración de recursos regionales destinados a acelerar la aplicación de la Iniciativa Mundial en América Latina y el Caribe.En marzo del 2021, la OPS formó grupos de trabajo regionales para elaborar proyectos básicos que estuvieran en consonancia con los pilares y los elementos facilitadores del CureAll. De los diálogos regionales surgieron siete grupos de trabajo: detección temprana, enfermería, aspectos psicosociales, nutrición, tratamientos de apoyo, abandono del tratamiento y cuidados paliativos. La OPS organizó con regularidad reuniones virtuales en las que se contó con la tutoría y el apoyo de programas regionales o transversales del St. Jude Children's Research Hospital y de mentores internacionales.Entre abril y diciembre del 2021 hubo 43 reuniones virtuales a las que asistieron 202 expertos multidisciplinarios, con el objetivo de promover el diálogo entre las partes interesadas para mejorar los resultados en materia de cáncer infantil. Se elaboraron catorce productos técnicos: cuatro panoramas regionales, cuatro documentos técnicos, dos cursos virtuales, un conjunto de perfiles epidemiológicos de países, una serie con contenidos educativos para padres y cuidadores y dos campañas de comunicación.El diálogo y el compromiso constantes de la OPS, el St. Jude Children's Research Hospital, los comités de trabajo de América Latina y el Caribe y los colaboradores internacionales son las bases fundamentales para conseguir que se acelere la aplicación de la Iniciativa Mundial. Esto se puede lograr mediante la elaboración de materiales que resulten pertinentes a nivel regional y mundial. Son necesarias más investigaciones y evaluaciones para determinar el impacto que tienen estas estrategias y recursos en los resultados que se obtienen en el cáncer infantil en América Latina y el Caribe y en otras subregiones.

RESUMEN
Cervical cancer remains a leading cause of cancer death for women in low- and middle-income countries. The goal of our study was to evaluate screening and triage strategies, including high-resolution microendoscopy (HRME), to detect cervical abnormalities concerning for precancer at the point of care. Women (n = 1824) were enrolled at the Instituto de Cáncer de El Salvador. All underwent screening by both human papillomavirus (HPV) testing using careHPV and visual inspection with acetic acid (VIA). Screen-positives, along with 10% of screen-negatives, were invited to return for a follow-up examination that included triage with VIA, colposcopy and HRME imaging. Biopsies were taken of any abnormalities identified. If no abnormalities were identified, then the worst scoring site by HRME was biopsied. The sensitivities of HPV testing and VIA to screen for cervical intraepithelial neoplasia Grade 2 or more severe diagnoses (CIN2+) were 82.1% and 75% (P = .77), while the specificities were 90.4% and 80.9% (P < .001), respectively. The sensitivities of VIA, colposcopy and HRME as triage tests for CIN2+ were 82.1%, 82.1% and 71.4%, respectively (P ≥ .38). HRME had a significantly higher specificity (66.7%) than VIA (51.9%) (P < .001) and colposcopy (53.3%) (P < .001). When evaluating different theoretical screening and triage strategies, screening with HPV testing followed by triage with HRME would result in more women receiving appropriate care (97%) compared to screening with VIA (75%) or HPV alone (90%). Our findings demonstrate that screening with HPV is superior to VIA, and that triage with HRME imaging increases the specificity of detecting CIN2+ at the point of care in a low-resource setting.
RESUMEN
Cervical cancer screening with human papillomavirus (HPV) DNA testing has been incorporated into El Salvador's national guidelines. The feasibility of home-based HPV self-collection among women who do not attend screening at the clinic (i.e., non-attenders) has been demonstrated, but cost-effectiveness has not been evaluated. Using cost and compliance data from El Salvador, we informed a mathematical microsimulation model of HPV infection and cervical carcinogenesis to conduct a cost-effectiveness analysis from the societal perspective. We estimated the reduction in cervical cancer risk, lifetime cost per woman (2017 US$), life expectancy, and incremental cost-effectiveness ratio (ICER, 2017 US$ per year of life saved [YLS]) of a program with home-based self-collection of HPV (facilitated by health promoters) for the 18% of women reluctant to screen at the clinic. The model was calibrated to epidemiologic data from El Salvador. We evaluated health and economic outcomes of the self-collection intervention for women aged 30 to 59â¯years, alone and in concert with clinic-based HPV provider-collection. Home-based self-collection of HPV was projected to reduce population cervical cancer risk by 14% and cost $1210 per YLS compared to no screening. An integrated program reaching 99% coverage with both provider- and home-based self-collection of HPV reduced cancer risk by 74% (compared to no screening), and cost $1210 per YLS compared to provider-collection alone. Self-collection facilitated by health promoters is a cost-effective strategy for increasing screening uptake in El Salvador.

INTRODUCTION: Gas-based cryotherapy is the conventional ablative treatment for cervical pre-cancer in low-income settings, but the use of gas poses significant challenges. We compared the depth of necrosis induced by gas-based cryotherapy with two gas-free alternatives: cryotherapy using CryoPen,and thermoablation. METHODS: We conducted a five-arm randomized non-inferiority trial: double-freeze carbon dioxide (CO2) cryotherapy (referent), single-freeze CO2 cryotherapy, double-freeze CryoPen, single-freeze CryoPen, and thermoablation. Subjects were 130 women scheduled for hysterectomy for indications other than cervical pathology, and thus with healthy cervical tissue available for histological evaluation of depth of necrosis post-surgery. The null hypothesis was rejected (ie, conclude non-inferiority) if the upper bound of the 90% confidence interval (90% CI) for the difference in mean depth of necrosis (referent minus each experimental method) was <1.14 mm. Patient pain during treatment was reported on a scale of 0 (no pain) to 10 (worst pain). RESULTS: A total of 133 patients were enrolled in the study. The slides from three women were deemed unreadable. One patient was excluded because her hysterectomy was postponed for reasons unrelated to the study, and two patients were excluded because treatment application did not follow the established protocol. For the remaining 127 women, mean depth of necrosis for double-freeze CO2 (referent) was 6.0±1.6 mm. Differences between this and other methods were: single-freeze CO2 = 0.4 mm (90% CI -0.4 to 1.2 mm), double-freeze CryoPen= 0.7 mm (90% CI 0.04 to 1.4 mm), single-freeze CryoPen= 0.5 mm (90% CI -0.2 to 1.2 mm), and thermoablation = 2.6 mm (90% CI 2.0 to 3.1 mm). Mean pain levels were 2.2±1.0 (double-freeze CO2 cryotherapy), 1.8±0.8 (single-freeze CO2 cryotherapy), 2.5±1.4 (double-freeze CryoPen), 2.6±1.4 (single-freeze CryoPen), and 4.1±2.3 (thermoablation). DISCUSSION: Compared with the referent, non-inferiority could not be concluded for other methods. Mean pain scores were low for all treatments. Depth of necrosis is a surrogate for treatment efficacy, but a randomized clinical trial is necessary to establish true cure rates.
RESUMEN
OBJECTIVE: The aim of the study was to evaluate the impact of maintenance on performance of cryosurgical equipment used in El Salvador primary health clinics. MATERIALS AND METHODS: Nine gynecological cryotherapy devices used in El Salvador were bench tested against a new machine of the same make and model. The devices were run for five successive double-freeze cycles. The El Salvador machines then received maintenance by a specialized engineer and another double-freeze cycle was performed. Temperature at the device probe tip was recorded throughout each cycle and ballistic gelatin was used as the tissue analogue to measure freeze ball dimensions achieved by the devices. Outcome measures were mean lowest-sustained temperatures and freeze ball mean weight, depth, and diameter. Paired and unpaired t tests were used to compare results premaintenance versus postmaintenance and postmaintenance versus the reference, respectively. RESULTS: Premaintenance versus postmaintenance freeze ball dimensions were significantly different (mean differences in weight = 2.31 g, p = .01; depth = 2.29 mm, p = .03; diameter = 3.51 mm, p = .02). However, postmaintenance dimensions were not significantly different than those of the reference (weight = 7.44 g vs. 8.39 g, p = .07; depth = 10.71 vs. 11.24 mm, p = .1; diameter = 31.38 mm vs. 32.05 mm, p = .3). Postmaintenance, minimum, and lowest-sustained temperatures were within the recommended clinical range. CONCLUSIONS: Specialized maintenance was necessary for heavily used cryotherapy devices to perform adequately, highlighting the challenges of gas-based cryotherapy in low- and middle-income countries.

Cervical cancer is a preventable disease with a known etiology (human papillomavirus), effective preventive vaccines, excellent screening methods, and a treatable pre-invasive phase. Surgery is the primary treatment for pre-invasive and early-stage disease and can safely be performed in many low-resource settings. However, cervical cancer rates remain high in many areas of Latin America. This article presents a number of evidence-based strategies being implemented to improve cervical cancer outcomes in Latin America.

The accumulated scientific evidence now provides ample support for HPV primary screening as a superior method for detecting cervical precancer and preventing cervical cancer. Approximately half of the global burden of cervical cancer could be reduced in lower-middle income countries where attempts to implement traditional cytology-based programs have not experienced successes. In these countries screening programs have struggled with poor screening and diagnostic test sensitivity, difficulties maintaining quality control and adequate population coverage. HPV testing is not only more accurate and reliable, but also requires less training, quality assurance and expensive personnel. Because these countries are especially vulnerable to economic, political and societal instabilities, HPV tests must become more affordable and accessible in order to enable Ministries of Health to make long-term resource commitments.

OBJECTIVE: The Cervical Cancer Prevention in El Salvador is a demonstration project to introduce a lower-cost human papillomavirus (HPV)-DNA test into a public sector project. Started in October 2012, The Cervical Cancer Prevention in El Salvador consists of 3 phases and will ultimately screen 30,000 women. Results of phase 2 of the project are presented. The objective of this project was to compare colposcopy and noncolposcopy-based management for HPV-positive women. MATERIAL AND METHODS: In phase 2, a total of 8,050 women, aged 30 to 49 years, were screened; 6,761 provided both self- and provider-collected specimens and 1,289 provided only provider-testing specimens. HPV results from self-collected specimens were not used in clinical management decisions. Women with provider-collected HPV-positive results were treated based on the strategy assigned to their community; the strategy was colposcopy management (CM) or screen-and-treat (ST) management if they were cryotherapy eligible or colposcopy if not eligible. Outcomes were assessed 6 months after screening. RESULTS: Overall, 489 (12.3%) of 3,963 women receiving CM and 465 (11.4%) of 4,087 women receiving ST tested HPV positive. In the CM cohort, 216 (44.2%) of 489 completed their intervention (203 treated, 11 diagnosed negative, 2 pregnant). In the ST cohort, 411 (88.4%) of 465 completed their intervention (407 treated, 2 diagnosed negative, 1 pregnant). Overall agreement between HPV test results from self-collected and provider-collected specimens was 93.7%, with a κ value of 0.70 (95% CI = 0.68-0.73). CONCLUSIONS: Human papillomavirus testing with ST management resulted in an approximately twice completion rate compared with CM management. Agreement between self- and provider-based sampling was good and might be used to extend screening to women in areas that are more difficult to reach.
