Childhood cancer survivors: current challenges.

Rates of childhood cancer survival in developed countries have risen to over 80-85 %. In consequence, the population of childhood cancer survivors (CCS) has grown considerably. Nevertheless, CCS present a high morbidity and mortality due to cancer or its treatment, with an increased risk of premature mortality, second primary tumors and late side effects, both physical and psychosocial, all of which decrease the quality of life. Long-term follow-up (LTFU) of CCS is recommended to prevent, detect and treat those health problems. Despite the advances achieved, the management of CCS is still not optimal. Among the areas for improvement discussed in this manuscript are: (1) Quantifying the real burden of morbimortality, by implementing new frequency measures (mean cumulative count and cumulative burden), to obtain more accurate assessments, and using simulation models, to determine individual risks; (2) Assessing the impact of risk factors for late side effects, related to the patient, tumor type, treatments, lifestyle, comorbidities, genetics and ageing; (3) Considering the impact of the international harmonisation of long-term follow-up guidelines, to generate homogeneous, evidence-based recommendations and an individualized LTFU and, (4) Challenges to LTFU implementation, considering models of care adapted to patient risk and needs, with special attention to the transition to adult-care follow-up. Finally, we comment on the situation of CCS in Spain and consider future prospects for improving the health and quality of life of this population.

Ajuste y adaptación psicosocial de adultos jóvenes supervivientes de un cáncer en etapa pediátrica: Revisión sistemática / Psychosocial adjustment and adaptation in young adults surviving pediatric cancer: A systematic review

Introducción: Los efectos a largo plazo de tumores en la infancia pueden alterar la trayectoria de adaptación y ajuste psicosocial de los supervivientes en etapas de vida posteriores. Objetivo: Esta revisión sistemática se centra en analizar las experiencias de crecimiento postraumático, estrés postraumático, malestar emocional y dificultades psicosociales sufridas por jóvenes adultos supervivientes a un cáncer en etapa pediátrica. Resultados: Los resultados sugieren una trayectoria mayoritaria que podría definirse como adaptativa, en la que se observa tanto crecimiento postraumático (prevalencia superior al 60%), como síntomas de estrés postraumático (prevalencia inferior al 30%). No obstante, en comparación con población control no oncológica, estos supervivientes tienen mayor riesgo de padecer síntomas de ansiedad y depresión, de alcanzar menores logros educativos y profesionales, y de permanecer solteros o vivir solos, lo que se hipotetiza que podría estar relacionado con las secuelas de cada tipo de tumor y tratamiento, y no únicamente con la vivencia de la enfermedad. Conclusiones: La atención a jóvenes adultos supervivientes a un cáncer pediátrico debería centrarse en proporcionar mayor apoyo médico y psicosocial a largo plazo, a través del abordaje interdisciplinar y la atención centrada en la persona, como aproximación que favorezca una trayectoria de ajuste adaptativa.(AU)

Introduction: Long-term effects of childhood tumors can alter the trajectory of adjustment and psychosocial adjustment of survivors later in life. Purpose: This systematic review focuses on analyzing the experiences of posttraumatic growth, posttraumatic stress, emotional distress, and psychosocial difficulties experienced by young adult survivors of pediatric cancer. Results: The results suggest a more prevalent trajectory that could be conceptualize as adaptive, in which both post-traumatic growth (prevalence greater than 50%) and post-traumatic stress symptoms (prevalence less than 30%) are observed. However, compared to the non-oncology control population, these survivors are at higher risk for anxiety and depressive symptoms, lower educational and occupational attainment, and remaining single or living alone, which is hypothesized to be related to the sequelae of each tumor type and treatment, and not just the disease experience. Conclusions: Care for young adult survivors of pediatric cancer should focus on providing enhanced long-term medical and psychosocial support through an interdisciplinary approach and person-centered care as an approach that supports a trajectory of adaptive adjustment.(AU)

Diastolic function assessment with left atrial strain in long-term survivors of childhood acute lymphoblastic leukemia.

INTRODUCTION AND OBJECTIVES: Survivors of childhood cancer might be at increased risk of diastolic dysfunction at follow-up due to exposure to cardiotoxic treatment. Although assessment of diastolic function is challenging in this relatively young population, left atrial strain might provide a novel insight in this evaluation. Our aim was to examine diastolic function in a cohort of long-term survivors of childhood acute lymphoblastic leukemia by using left atrial strain and conventional echocardiographic parameters. METHODS: Long-term survivors who were diagnosed at a single center between 1985 and 2015 and a control group of healthy siblings were recruited. Conventional diastolic function parameters and atrial strain were compared, and the latter was measured during the 3 atrial phases: reservoir (PALS), conduit (LACS) and contraction (PACS). Inverse probability of treatment weighting was used to account for differences between the groups. RESULTS: We analyzed 90 survivors (age, 24.6±9.7 years, time since diagnosis 18 [11-26] years) and 58 controls. PALS and LACS were significantly reduced compared with the control group: 46.4±11.2 vs 52.1±11.7; P=.003 and 32.5±8.8 vs 38.2±9.3; P=.003, respectively. Conventional diastolic parameters and PACS were similar between the groups. The reductions in PALS and LACS were associated with exposure to cardiotoxic treatment in age- and sex-adjusted analysis (≥ moderate risk, low risk, controls): 45.4±10.5, 49.5±12.9, 52.1±11.7; Padj=.003, and 31.7±9.0, 35.2±7.5, 38.2±9.3; Padj=.001, respectively. CONCLUSIONS: Long-term childhood leukemia survivors showed a subtle impairment of diastolic function that was detected with atrial strain but not with conventional measurements. This impairment was more pronounced in those with higher exposure to cardiotoxic treatment.

Percepciones de las enfermeras de oncología infantil relacionadas con el perfil, capacitación, emociones y reacciones en la valoración del niño con dolor / Perceptions of pediatric oncology nurses related to the profile, training, emotions, and reactions in the assessment of children with pain

El cáncer es una de las principales causas de mortalidad en la niñez y la adolescencia. Tanto el impacto biopsicosocial y espiritual que produce, puede llevar al niño a experimentar dolor y sufrimiento. OBJETIVO: Comprender aspectos comunes percibidos por la enfermera oncológica y como se relacionan en la valoración de un niño con dolor. MÉTODO: se trató de un estudio cualitativo con diseño de teoría fundamentada de datos según referencial metodológico de Strauss y Corbin. Por medio de muestreo teórico fueron seleccionados 13 participantes profesionales de enfermería pertenecientes a diferentes hospitales de Santiago de Chile. Los datos fueron recolectados a través de entrevistas semiestructuradas y en profundidad. El estudio se rigió por medio de los criterios de credibilidad, confirmabilidad y fidelidad de Guba y Lincoln. Los datos recolectados fueron transcritos posterior a cada entrevista y analizados en tres etapas: codificación abierta, axial y selectiva. RESULTADOS: para las enfermeras que trabajan en el área de oncología infantil, es central el cuidado entregado en el proceso de enfermedad del niño hospitalizado por cáncer, considerando aspectos como el perfil de las profesionales, las emociones, la capacitación, las reacciones frente a un niño con dolor y las relaciones que existe entre ellos. CONCLUSIONES: Existen aspectos que resultan común en las enfermeras que se desempeñan en oncología infantil y que producto de las relaciones existentes entre ellos, pueden inclinar a las profesionales a reconocer el dolor en los niños con cáncer desde diversas perspectivas.

Cancer is one of the main causes of mortality in childhood and adolescence. Both the biopsychosocial and spiritual impact it produces can lead the patient child to experience pain and suffering. OBJETIVE: To understand common aspects perceived by the oncology nurse and how they are related to the assessment of a child in pain. METHOD: We conducted a qualitative study with a grounded theory approach based on Strauss and Corbin's methodological framework. Through theoretical sampling, 13 nursing professionals who worked in different hospitals in Santiago, Chile were selected. Data collection took place through semi-structured, in-depth interviews. The study followed Guba and Lincoln's criteria for credibility, confirmability, and fidelity. The data collected was transcribed after each interview and analyzed in three stages: open, axial and selective coding. RESULTS: For nurses who work in pediatric oncology, the care provided throughout the illness process for the child is central, considering aspects such as the profile of the professionals, the emotions, training, reactions to a child in pain, and the relationship that exist amongst them. CONCLUSIONS: There are common aspects amongst nurses who work in pediatric oncology. Because of the relationships between them, these aspects can help professionals to recognize pain in children with cancer following diverse perspectives.

Estilos de humor, afrontamiento y soporte social en padres de niños con cáncer

Objetivo: Analizar el rol predictivo de las estrategias de afrontamiento y el soporte social percibido, sobre los estilos de humor en padres migrantes de niños con cáncer. Método: Se empleó un diseño cuantitativo transaccional-correlacional y un muestreo no probabilístico por conveniencia. Participaron 62 progenitores (11 hombres y 51 mujeres) entre los 20 y 61 años, quienes respondieron la Escala del Sentido del Humor (HSQ), el Cuestionario de Estimación del Afrontamiento (COPE) y el Medical Outcomes Study Social Support Survey (MOS-SSS). Resultados: Se establecieron modelos de regresión para el humor afiliativo (R²=0,19, p<0,001) y agresivo (R²=0,25, p<0,001), ambos considerados estilos de humor orientados a los demás. Respecto a los estilos orientados a uno mismo, para el humor de mejoramiento personal se desarrollaron dos modelos, el primero considera el soporte social global (R²=0,25, p< 0,001) y el segundo el soporte afectivo (R²=0,27, p< 0,001); y de la misma forma para el humor de descalificación personal, un modelo incluye el soporte social global (R²=0,28, p< 0,001) y el segundo el soporte instrumental (R²=0,27, p< 0,001). Conclusión: Las estrategias de afrontamiento y el soporte social en relación con los estilos de humor en contexto de enfermedad y migración demuestra la efectividad de ciertas estrategias y estilos considerados desadaptativos ante una situación altamente estresante.

Objective: To analyze the predictive role of coping strategies and social support over humor styles in parents who migrate along with children with cancer. Method: A transactional-correlational quantitative design and non-probabilistic convenience sampling were used. It involved 62 parents (11 men and 51 women) between 20 and 61 years. They answered the Humor Styles Questionnaire (HSQ), COPE Inventory (COPE) and the Medical Outcomes Study Social Support Survey (MOS-SSS). Results: Regression models were developed for affiliative (R²=0,19, p<0,001) and aggressive humor (R²=0,25, p<0,001), both considered humor styles towards others. For self-oriented humor styles, two models were built to predict self-enhancing humor. The first model considers global social support (R²=0,25, p<0,001), while the second model, affective support (R²=0,27, p<0,001). Likewise, the first model explaining self-defeating humor considers global social support (R²=0,28, p<0,001) and the second, instrumental support (R²=0,27, p<0,001). Discussion: Coping strategies and social support in relation to humor styles in the context of illness and migration demonstrate the effectiveness of certain strategies and styles considered maladaptive in face of a highly stressful situation.

Validación de la herramienta de tamizaje nutricional para el cáncer infantil SCAN. Versión en español / Validation of the nutritional screening tool for childhood cancer SCAN. Spanish version

Introducción: la prevalencia de la desnutrición en la población con cáncer infantil puede variar notablemente, elemento que influye de manera significativa en el desenlace clínico de los pacientes. No obstante, este es un factor pronóstico potencialmente modificable y para ello se requiere una identificación del riesgo nutricional oportuna que oriente el proceso de cuidado nutricional. Objetivo: evaluar el rendimiento operativo de la versión en español de la escala de tamización nutricional para el cáncer infantil (SCAN-SP) en el marco del proceso de validación del instrumento en un hospital de alta complejidad en la ciudad de Bogotá, Colombia. Métodos: se siguió el diseño metodológico para la validación de una escala diagnóstica. La muestra final fue de 96 pacientes entre los 0 y 17 años con cáncer y hospitalizados en el Centro de Cáncer Infantil de la Fundación HOMI en Bogotá. A cada paciente se le aplicó la SCAN-SP y también se le realizó una valoración nutricional completa (VNC) tomada como patrón de referencia para conocer su estado nutricional. Resultados: el 82,3 % (n = 79) de los pacientes fueron clasificados como “con riesgo de desnutrición” por la SCAN-SP y el 69,8 % (n = 67) del total de la muestra estaban realmente desnutridos. La evaluación del rendimiento operativo de la SCAN-SP contra la VNC mostro excelentes resultados: sensibilidad del 100 %, especificidad del 59 %, VPP del 85 %, VPN del 100 %, RVP de 2,4 y una RVN de 0. Conclusión: la escala SCAN-SP tiene un buen comportamiento como herramienta de tamización nutricional en el paciente pediátrico con cáncer, por lo que se recomienda su uso en la práctica clínica. (AU)

Introduction: the prevalence of undernutrition in the pediatric cancer population can vary considerably, an element that significantly influences the clinical outcome of patients. However, this is a potentially modifiable prognostic factor, which requires timely identification of nutritional risk to guide the nutritional care process. Objectives: to evaluate the operational performance of the Spanish version of the nutritional screening tool for childhood cancer (SCAN) in the context of the validation process of this instrument in a high-complexity hospital in the city of Bogotá, Colombia. Methods: the methodological design for the validation of a diagnostic scale was followed. The final sample consisted of 96 patients between 0 and 17 years with cancer and hospitalized at the Children’s Cancer Center of the HOMI Foundation in Bogota. The SCAN-SP was applied to each patient and a complete nutritional assessment (CNA) was performed as a gold standard to determine nutritional status. Results: 82.3 % (n = 79) of patients were classified “at risk of malnutrition” by SCAN-SP and 69.8 % (n = 67) of the total sample had undernutrition. The evaluation of the operative performance of SCAN-SP against CNA showed excellent results: sensitivity of 100 %, specificity of 59 %, PPV of 85 %, NPV of 100 %, positive likelihood ratio of 2.4, and negative likelihood ratio of 0.Conclusion: the SCAN-SP scale performs well as a nutritional screening tool in pediatric cancer patients, so its use in clinical practice is recommended.

Cáncer infantil: lo que debemos saber / Childhood cáncer: What we should know

Introducción: el cáncer representa una de las principales causas de muerte en niños, niñas y adolescentes a nivel global, el cual es superado escasamente por los accidentes. Las neoplasias más frecuentes son, en primer lugar, las leucemias; segundo, los tumores del Sistema Nervioso Central; y, tercero, los linfomas. Es importante destacar que no existe prevención, sin embargo, hay signos de alarma que si se logran identificar a tiempo pueden verse traducidos en una enfermedad más manejable con una sobrevida más alta y un mejor pronóstico. Objetivo: realizar una actualización académica sobre la importancia de los signos y síntomas de alarma del cáncer infantil. Método: se realizó una investigación documental y se utilizó como buscador de información científica Google Académico. Se evaluaron artículos de investigación y revisión de diferentes bases de datos, como: site de la Organización Mundial de la Salud, site de la Oficina Panamericana de la Salud, Revista de Pediatría Integral, American Cáncer Society y publicaciones periodísticas locales, entre otros. Conclusiones: el cáncer en la infancia y adolescencia no puede prevenirse; sin embargo, si los médicos de los distintos niveles de atención en salud pueden reconocer los signos de alarma ante un probable caso de malignidad, se lograrán referimientos oportunos, diagnósticos tempranos y una mejor tasa de curabilidad y sobrevida en los niños.

Introduction: Cancer represents one of the main causes of death in children and adolescents globally, which is barely surpassed by accidents. The most frequent neoplasms are leukemias first, Central Nervous System tumors second, and lymphomas third. It is important to note that there is no prevention, however, there are warning signs that, if identified in time, can be translated into a more manageable disease with higher survival and a better prognosis. Objective: To carry out an academic update on the importance of warning signs and symptoms of childhood cancer. Method: A documentary research was carried out and Google Scholar was used as a search engine for scientific information. Research and review articles from different databases were evaluated, such as: the World Health Organization site, the Pan American Health Office site, the Comprehensive Pediatrics Review, the American Cancer Society, local journalistic publications, among others. Conclusions: Cancer in childhood and adolescence cannot be prevented, however, if doctors at the different levels of health care can recognize the warning signs in the event of a probable case of malignancy, timely referrals, early diagnoses and a better curability rate will be achieved and survival in children.

Physical activity of children with cancer during the COVID-19 pandemic: what were the most relevant studies published from August 2019 to July 2021? / Actividad física em niños con cáncer durante la covid-19: ¿cuáles fueron las publicaciones más relevantes entre agosto de 2019 y julio de 2021? / Atividade física de crianças com câncer durante a covid-19: o que foi publicado de mais relevante entre agosto de 2019 e julho de 2021?

ABSTRACT This study aims to investigate up-to-date scientific information about physical activity, COVID-19, and childhood cancer. This study is an integrative review. Research was conducted in the Science Direct database, using keywords in three different combinations. In total, 50 publications classified as the most relevant of each keyword combination were selected, 26 eligible publications were reached from August 2019 to July 2021, of which nine were duplicates. When exclusion criteria were applied, 11 complete studies were selected. The level of physical activity (PA) of children diagnosed with cancer or those who survived cancer is low. Changes due to the COVID-19 pandemic include the decrease in the level of PA and the increase in the use of technological devices. The minimum PA recommendations for this population vary but some evidence supports its importance and benefits in minimizing the adverse effects arising from cancer and from the performed medical treatment. Exercise-based interventions should be chosen and carried out considering the type of cancer and the stage of treatment the child is in due to the evidence of its effectiveness.

RESUMEN Este estudio tiene como objetivo investigar, en la base de datos ScienceDirect, la información científica actualizada sobre actividad física, COVID-19 y cáncer infantil, mediante una revisión integradora, en la cual se utilizaron las palabras clave en tres combinaciones diferentes. Se seleccionaron cincuenta publicaciones clasificadas como las más relevantes de cada combinación, y se alcanzaron 26 publicaciones elegibles en el periodo entre agosto de 2019 y julio de 2021, de las cuales nueve fueron textos duplicados. Al aplicar los criterios de exclusión, se seleccionaron 11 artículos completos. El nivel de actividad física (AF) de los niños diagnosticados de cáncer o supervivientes de cáncer es bajo, y entre los cambios provocados por la pandemia de la COVID-19 se encuentran la disminución del nivel de AF y el aumento en el uso de dispositivos tecnológicos. Las recomendaciones mínimas de AF para esta población varían entre sí, sin embargo, existe evidencia que respalda su importancia y los beneficios en la minimización de los efectos adversos derivados del propio cáncer y del tratamiento médico realizado. Las intervenciones basadas en ejercicios, para la cual ya existe evidencia de efectividad, deben elegirse y llevarse a cabo teniendo en cuenta el tipo de cáncer y la etapa de tratamiento en la que se encuentra el niño.

RESUMO O objetivo deste trabalho é investigar, na base de dados Science Direct, informações científicas sobre atividade física, covid-19 e câncer infantojuvenil, através de uma revisão integrativa, utilizando três combinações de palavras-chave. Cinquenta publicações mais relevantes de cada combinação de palavras-chave foram selecionadas, e chegou-se a 26 artigos elegíveis no período compreendido entre agosto de 2019 e julho de 2021, dos quais nove eram textos duplicados. Aplicando-se os critérios de exclusão, foram selecionados 11 estudos completos. Constatou-se que o nível de atividade física (AF) de crianças com câncer ou sobreviventes do câncer é baixo e que entre as mudanças causadas pela pandemia de covid-19 estão a diminuição do nível de AF e o aumento do uso de dispositivos tecnológicos. As recomendações mínimas de AF para essa população variam, entretanto há evidências que sustentam sua importância e seus benefícios ao minimizar os efeitos adversos oriundos do próprio câncer e do tratamento médico realizado. As intervenções baseadas em exercícios, para as quais já há evidência de eficácia, devem ser escolhidas e realizadas a partir do tipo de câncer e na fase do tratamento em que a criança está.

Fear of cancer recurrence in informal caregivers of childhood cancer survivors / Miedo a la recurrencia del cáncer en cuidadores de supervivientes de cáncer infantil

Abstract Background Fear of cancer recurrence is one of the most distressing psychological consequences in cancer survivors and their informal primary caregivers (IPC). IPC of childhood cancer survivors (CCS) are often their mothers, which could intensify fear of cancer recurrence (FCR) and its impact on both IPC and CCS. However, the phenomenon has not been widely described in this specific population. Objective To summarize and analyze current evidence on the evaluation and management of FCR among IPC of CCS. Method A narrative review of studies included in four databases (PsycInfo, Medline, CINALH, and Web of Science) with no language or year of publication restrictions. Results Measures specifically developed to assess FCR among IPC of CCS comprising an interview and a questionnaire with initial psychometric evaluations and two short, online intervention programs based on cognitive-behavioral-contextual therapy were identified (ENGAGE and CASCAdE). Both have demonstrated acceptability in parents of CCS in high-income countries; preliminary evidence also exists of the effectivity of CASCAdE in reducing FCR. Discussion and conclusion Given the limitations of this area of psychological evaluation, the Fear of Cancer Recurrence Inventory, originally developed for adult cancer survivors, constitutes the most suitable tool for evaluating FCR among IPC of CCS. The CASCAdE program seems a promising intervention for IPC of CSS, although cultural adaptations, evaluations of its acceptability in low- and middle-income countries, and controlled studies in large samples are still required.

Resumen Antecedentes El miedo a la recurrencia del cáncer es una de las consecuencias psicológicas más angustiantes en los supervivientes y sus cuidadores primarios informales (CPI). Los CPI de supervivientes de cáncer infantil (SCI) a menudo son sus madres, lo que podría intensificar el miedo a la recurrencia (MR) y su impacto tanto a los CPI como a los SCI. Sin embargo, el fenómeno no se ha descrito ampliamente en esta población específica. Objetivo Resumir y analizar la evidencia actual sobre la evaluación y manejo del MR entre CPI de SCI. Método Se realizó una revisión narrativa de los estudios incluidos en cuatro bases de datos (PsycInfo, Medline, CINALH y Web of Science) sin restricciones de idioma o año de publicación. Resultados Se identificaron instrumentos desarrollados específicamente para evaluar MR entre CPI de SCI que comprenden una entrevista y un cuestionario, además de dos programas de intervención en línea basados en terapia cognitivo-conductual-contextual (ENAGE y CASCAdE). Ambos demostraron aceptabilidad en los padres de SCI en países de ingresos altos. También existe evidencia preliminar de la efectividad de CASCAdE en la disminución del MR. Discusión y conclusión Dadas las limitaciones de esta área de evaluación psicológica, el Inventario del Miedo a la Recurrencia del Cáncer, desarrollado originalmente para supervivientes adultos, constituye la herramienta más adecuada para evaluar MR en los CPI de SCI. El programa CASCAdE parece una intervención prometedora para CPI de SCI, aunque aún requiere adaptaciones culturales, evaluaciones de aceptabilidad en países de ingresos medio-bajos y estudios controlados con nuestras más grandes.

Posttraumatic growth among childhood cancer survivors and their care-givers: associations with rumination and beliefs challenge / Crecimiento postraumático entre sobrevivientes de cáncer infantil y sus cuidadores: asociaciones con rumiación y desafío de creencias

Abstract. The main purpose of the study was to assess the relationship between PTG, challenge to core beliefs, intrusive and deliberate rumination in a sample of 43 dyads of childhood cancer survivors and their caregivers. Methods: Survivors (mean age = 17.04; SD=3.67) and caregivers (mean age = 46.84; SD = 8.32) completed the Posttraumatic Growth Inventory (PTGI), the Core Beliefs Inventory (CBI) and the Event-related Rumination Inventory (ERRI). Results: Results showed a positive and high correlation among PTG, CBI, and ERRI in both groups, separately. CBI was the main predictor of PTG both among survivors (β=0.826; t=9.393; R²=0.683; p≤0.001) and caregivers (β=0.552; t=4.235; R²=0.304; p≤0.001). Caregivers reported higher scores than survivors in PTG (t=-2.999 p≤0.01) and its dimensions Relationship with others (t=2.498; p≤0.05), Spiritual change (t=-15.823; p≤0.001), Life appreciation (t=-3.129;

Resumen. El objetivo principal del estudio fue evaluar la relación entre el CPT, el desafío a las creencias, la rumiación intrusiva y deliberada en una muestra de 43 díadas de sobrevivientes de cáncer infantil y sus cuidadores. Métodos: Los sobrevivientes (edad media = 17,04; SD = 3,67) y los cuidadores (edad media = 46,84; SD = 8,32) completaron el Inventario de Crecimiento Postraumático (PTGI), el Inventario de Creencias Básicas (CBI) y el Inventario de Rumiación Relacionada con Eventos (ERRI). Resultados: Los resultados mostraron una correlación positiva y alta entre PTG, CBI y ERRI en ambos grupos, por separado. El CBI fue el principal predictor de CPT tanto entre los sobrevivientes (β=0,826; t=9,393; R²=0,683; p≤0,001) como entre los cuidadores (β=0,552; t=4,235; R²=0,304; p≤0,001). Los cuidadores reportaron puntajes más altos que los sobrevivientes en CPT (t=-2,999 p≤0,01) y sus dimensiones Relación con los demás (t=2,498; p≤0,05), Cambio espiritual (t=-15,823; p≤0,001), Valoración de la vida (t =-3,129;

Análisis de conglomerado de cáncer infantil y su relación con proximidad a fuentes de contaminación industrial en el Área Metropolitana del Valle de Aburrá, 2000-2015

Objetivo: Este estudio evaluó el efecto de la proximidad a fuentes industriales de contaminación del aire sobre la aparición de clústeres de casos de cáncer infantil en el Área Metropolitana del Valle de Aburrá, del departamento de Antioquia, durante el período 2000-2015. Metodología: La información de casos de cáncer infantil en menores de 15 años residentes del área metropolitana se obtuvo del Registro Poblacional de Cáncer de Antioquia, de dicho periodo. Se identificaron 32 conglomerados industriales, a partir del inventario de la autoridad ambiental local. Se realizaron pruebas de escaneo circular de Kulldorf locales y focalizadas, para detectar clústeres de cáncer infantil en los municipios y alrededor de los conglomerados industriales respectivamente. Se usó un modelo de regresión multivariable ajustado por estrato socioeconómico, para evaluar el efecto de las variables espaciales. Resultados: La tasa de incidencia específica en el Valle de Aburrá para el periodo evaluado fue de 117,13 casos por millón de niños menores de 15 años. Las tasas de incidencia más altas se presentaron en los municipios de Medellín y Sabaneta. La prueba de Kulldorf identificó 12 clústeres espaciales y 8 espacio-temporales con significación estadística en 7 de los municipios, particularmente en Bello y Medellín. Las pruebas focalizadas identificaron clústeres alrededor de 20 conglomerados industriales. En los modelos multivariables, un conglomerado en Bello evidenció asociación estadísticamente significativa e inversa entre la incidencia y la distancia al conglomerado con direccionalidad sureste. Conclusión: Algunos conglomerados espacio-temporales de cáncer infantil en el Área Metropolitana del Valle de Aburrá entre 2000 y 2015 están relacionados con proximidad a fuentes industriales de contaminación del aire.

Objective: This study evaluated the effect of proximity to industrial sources of air pollution on the occurrence of clusters of childhood cancer cases in the Aburrá Valley Metropolitan Area, Department of Antioquia, during the 2000-2015 period. Methodology: The information on childhood cancer cases in children under 15 years of age residing in the metropolitan area was obtained from the Registro Poblacional de Cáncer de Antioquia (Antioquia Cancer Population Registry) for that period. 32 industrial clusters were identified based on the local environmental authority's inventory. Local and targeted Kulldorff's circular scan tests were performed to detect childhood cancer clusters in the municipalities and surrounding the industrial clusters, respectively. We used a multivariate regression model adjusted for socioeconomic strata to assess the effect of spatial variables. Results: The specific incidence rate in the Aburrá Valley for the evaluated period was 117.13 cases per million children under 15 years of age. The highest incidence rates occurred in the municipalities of Medellín and Sabaneta. The Kulldorff test identified 12 spatial clusters and 8 space-time clusters that were statistically significant in 7 municipalities, particularly in Bello and Medellín. The targeted tests identified childhood cancer clusters surrounding 20 industrial clusters. In multivariate models, an industrial cluster in Bello showed a statistically significant inverse association between incidence and distance from the industrial cluster toward the southeast. Conclusion: Some space-time childhood cancer clusters in the Aburrá Valley Metropolitan Area between 2000 and 2015 are related to proximity to industrial sources of air pollution.

Metodología: A informação de casos de câncer infantil em menores de 15 anos residentes da área metropolitana foi obtida do Registro Populacional de Câncer de Antioquia, de tal período. Foram identificados 32 conglomerados industriais, a partir do inventário da autoridade ambiental local. Foram realizados testes de varredura circular de Kulldorf locais e focalizados, para detectar agrupações de casos de câncer infantil nos municípios e ao redor dos conglomerados industriais, respectivamente. Foi usado um modelo de regressão multivariável ajustado por nivel socioeconômico, para avaliar o efeito das variáveis espaciais. Resultados: A taxa de incidência específica no Valle de Aburrá para o período avaliado foi de 117,13 casos por milhão de crianças menores de 15 anos. As maiores taxas de incidencia apresentaram-se nos municípios de Medellín e Sabaneta. O teste de Kulldorf identificou 12 agrupações de casos espaciais e 8 espaço-temporais com significação estatística em 7 dos municípios, particularmente em Bello e Medellín. As provas focalizadas identificaram agrupações de casos ao redor de 20 conglomerados industriais. Nos modelos multivariáveis, um conglomerado em Bello evidenciou associação estatisticamente significativa e inversa entre a incidência e a distância com o conglomerado orientado ao sudeste. Conclusão: Algumas agrupações de casos espaço-temporais de câncer infantil na Área Metropolitana do Valle del Aburrá entre 2000 e 2015 estão relacionadas com a proximidade a fontes industriais de poluição do ar.

Para la intervención se adaptaron: Métodos, contexto y objetivos, dando como resultado la aplicación individual, cambios en el diseño gráfico e inclusión de iconografías llamativas y amigables para los padres (aceptabilidad). En la evaluación del contenido por jueces expertos se obtuvieron porcentajes del 50% de acuerdo en redacción de las sesiones de introducción del manual para el facilitador y 75% en redacción de la sesión cuatro del manual para padres. Conclusión: Este estudio muestra el proceso de adaptación cultural desde el MEV a fin de contar con los materiales necesarios para que la aplicación del programa CASCAdE en un contexto mexicano (AU)

Objective:Describe the process of the cultural adaptation of the CASCAdE intervention program for parents of childhood cancer survivors in Mexico. Method: The Ecological Validation Model (EVM) was used in two stages. The first consisted of the translation (from English to Spanish) and cultural adaptation of the program content while second involved the evaluation of the treatment content and integrity. Results. Changes were made in the wording of the text; the second person singular was changed to the third person singular “usted,” the formal way to say “you” in Spanish. The following were chosen from the EVM for the adaptation of materials: language, people, metaphors, or sayings, narrative and concepts. Among the most relevant changes are the use of the third person singular (acceptability) and the adaptation of metaphors to make them understandable in this context (relevance). The following aspects were adapted for the intervention: methods, context, and objectives, which resulted in individual application, changes in graphic design and the inclusion of attractive images for parents (acceptability). In the content evaluation by expert judges, 50% of agreement was obtained in the writing of the introductory sessions of the facilitator’s manual and 75% in the wording of session four of the parents’ manual. Conclusions. This study shows the process of cultural adaptation based on the EVM to obtain the necessary materials for the implementation of the CASCAdE program in a Mexican context (AU)

Más allá de la cura: la necesidad de implementar un sistema de seguimiento a largo plazo para los supervivientes de cáncer infantil en Colombia / Beyond the cure: the need to implement a long-term follow-up system for childhood cancer survivors in Colombia

Resumen Con el advenimiento de tratamientos multidisciplinarios y de alta calidad, la supervivencia global a cinco años por cáncer en la población pediátrica ha mejorado considerablemente, llegando a ser hasta de 80% en países de altos ingresos. En Colombia también ha habido un aumento progresivo de la supervivencia global a 5 años, particularmente para las neoplasias hematológicas. En consecuencia, el número de supervivientes de cáncer infantil ha aumentado de forma importante en los últimos años y junto con ellos la aparición de eventos adversos tardíos relacionados con mayor morbilidad y riesgo de muerte prematura en la edad adulta. Aunque se han venido implementando estrategias de seguimiento a supervivientes de cáncer infantil en países de altos ingresos, en Colombia se han realizado pocos esfuerzos para la implementación de estas estrategias. De hecho, la práctica común en la mayoría de los centros de tratamiento consiste en dar de alta al niño que cumple 5 años de seguimiento oncológico, sin instrucciones precisas para dicho seguimiento. El objetivo del presente trabajo es argumentar sobre la necesidad de diseñar e implementar estrategias de seguimiento para supervivientes de cáncer infantil en el contexto colombiano.

Abstract With the advent of high-quality multidisciplinary treatments, the overall 5-year cancer survival in the pediatric population has improved considerably, reaching up to 80% in high-income countries. In Colombia, there has also been a progressive increase in overall 5-year survival, particularly for hematologic malignancies. Consequently, the number of childhood cancer survivors has increased significantly in recent years and, together with them, the occurrence of late adverse events related to increased morbidity and risk of premature death in adulthood. Although follow-up strategies have been implemented for childhood cancer survivors in high-income countries, few efforts have been made in Colombia to implement these strategies. In fact, the common practice in most treatment centers is to discharge children who have had 5 years of cancer follow-up, without precise instructions for long-term follow-up. This paper aims to argue about the need to design and implement follow-up strategies for survivors of childhood cancer in the Colombian context.

Childhood acute lymphoblastic leukemia in Mexico: mortality trend analysis, 1998-2018 / Mortalidad por leucemia linfoblástica aguda en niños y adolescentes mexicanos: análisis de tendencias 1998-2018

Abstract: Objective: To determine the magnitude of mortality due to acute lymphoblastic leukemia (ALL) nationally and by age group, sex, state of residence and insurance status, as well as to evaluate time trends during the period 1998-2018 Materials and methods: We obtained ALL mortality data and estimated age-standardized national, state-level and health insurance mortality rates. We conducted a joinpoint regression analysis to describe mortality trends across the study period and estimate the average annual percent change (AAPC). Results: In a 20-year period, age-standardized ALL mortality rates increased from 1.6 per 100 000 in 1998 to 1.7 in 2018. Nationally, a constant annual increase in mortality was observed for both sexes (1998-2002 AAPC 0.6 in boys, and 1998-2002 AAPC 0.3 in girls). We observed heterogeneity in childhood ALL at a state level. Conclusion: Our results reflect the social, economic, geographic diversity of the country. Monitoring and surveillance of this disease is crucial to assess quality of care.

Resumen: Objetivo: Determinar la magnitud de mortalidad por leucemia linfoblástica aguda (LLA) infantil a nivel nacional, por grupo de edad, sexo, estado y derechohabiencia, así como evaluar las tendencias en el tiempo. Material y métodos: Se estimaron las tasas de mortalidad estandarizadas por edad y estratificadas. Se realizó un análisis de regresión joinpoint para estimar el cambio porcentual anual promedio (AAPC). Resultados: En un periodo de 20 años, las tasas de mortalidad por LLA aumentaron de 1.6 por 100 000 en 1998 a 1.7 en 2018. A nivel nacional, se observó un aumento anual constante para ambos sexos (1998-2002 AAPC 0.6 en niños, y 1998-2002 AAPC 0.3 en niñas). Existe heterogeneidad en la LLA infantil a nivel estatal. Conclusión: Los resultados reflejan la diversidad social, económica y geográfica del país. El seguimiento y la vigilancia de esta enfermedad es fundamental para evaluar la calidad de atención e implementar medidas para su control.

Qualidade de vida relacionada à saúde dos pais/responsáveis por crianças/adolescentes em tratamento para leucemia ou linfoma / Health-related quality of life of parents or caregivers responsible for children or adolescents in treatment for leukemia or lymphoma

Ao longo dos anos o câncer infanto-juvenil evoluiu de uma doença inevitavelmente fatal para uma condição crônica de saúde com risco de vida. A redução da taxa de mortalidade em decorrência da doença, se deu devido ao avanço contínuo da medicina e da eficácia dos tratamentos disponíveis. Os tipos de câncer mais prevalentes na infância são a leucemia e o linfoma, que podem levar até 3 anos de quimioterapia, variando entre fases mais e menos intensas. O extenso período do tratamento pode ser desgastante para o paciente e para o núcleo familiar, levando em consideração o número de consultas, internações, os sintomas que a própria doença pode causar e os efeitos colaterais advindos das medicações. Para avaliar o impacto que esses agravantes podem ter na qualidade de vida relacionada à saúde (QVRS) do paciente e da família, são necessárias pesquisas focadas na percepção e relato do próprio indivíduo (PROs). Desta forma, o objetivo do presente estudo foi identificar o impacto que a leucemia/linfoma e seu tratamento nas crianças/adolescentes podem causar na qualidade de vida dos pais/responsáveis e na família. Foi realizado um estudo transversal com amostra não probabilística de 52 famílias com crianças/adolescentes em tratamento para leucemia ou linfoma no Hospital das Clínicas da UFMG, Belo Horizonte, Brasil. Os responsáveis responderam sobre questões socioeconômicas e demográficas, e perguntas específicas da doença e do tratamento. O instrumento escolhido para mensurar o impacto da leucemia ou linfoma na QVRS dos familiares, foi a versão brasileira do PedsQLTM Family Impact Module. Foram realizadas análise descritiva dos dados e regressão logística bivariada e múltipla (IC 95%, P<0,05), usando o programa SPSS. As mães foram as principais respondentes responsáveis pelo paciente em tratamento (78,8%), a renda familiar mensal de 51,9% dos participantes era de até 1 salário mínimo e 65,4% compartilhavam a moradia com até 4 pessoas. Das crianças/adolescentes 88,5% estavam em tratamento para leucemia e 42,3% eram do sexo feminino. A análise múltipla revelou que a mãe, quando responsável pelo paciente em tratamento, possuía 13,9 vezes mais chances de apresentar maior impacto negativo na QVRS do que quando o responsável era representado por outra pessoa (OR=13,89 95%IC: 1,39-138,92; p=0,025). Outras variáveis independentes não estiveram associadas com impacto na QVRS das famílias. Considerando o autorrelato dos pais/responsáveis sobre o funcionamento parental, o maior impacto negativo foi relacionado com a preocupação (média=46,2; DP±25,56). Os domínios sobre funcionamento familiar "Atividades Cotidianas" e "Relacionamentos Familiares" apresentaram médias 64,4 (DP±36,60) e 84,4 (DP±25,25) respectivamente, representando maior comprometimento relacionado às atividades desenvolvidas no dia-a-dia, do que nos relacionamentos. Conclui-se que o câncer infantil e seu tratamento repercutem na QVRS da família. A mãe quando principal responsável pela criança/adolescente com câncer, apresenta mais chances de perceber o impacto negativo que a doença e o tratamento podem trazer ao núcleo familiar.

Throughout the years, pediatric cancer has evolved from a fatal disease to a chronic health condition with life threat. The reduction in the disease's mortality rate is due to the continuous advances in the field of medicine and the efficiency of available treatments. The most prevalent types of children's cancer are leukemia and lymphoma, each require until 3 years of chemotherapy varying in intensity throughout different phases. The lengthy treatment can be wearing to the patient and their families, considering the number of medical appointments, hospitalizations, and symptoms: adverse from the medication, and from the disease itself. To evaluate the impact that the aggravating factors can have on the patient's and related families' Health-Related Quality of Live (HRQoL) research focused on self-report is required. As so this study's objective is to identify the psychosocial impact that leukemia/lymphoma and its treatment in children/adolescents can cause in the parents/guardians and family's lives. A cross-sectional study was conducted with a non-probability sample of 52 families with children/adolescents under treatment for leukemia or lymphoma at a reference hospital in Belo Horizonte, Brazil. The parents/guardians answered questions about their socioeconomical and demographical status and questions related to the disease, and its treatments. The Brazilian version of PedsQLTM Family Impact Module was also used to measure the possible impact of leukemia and lymphoma on the HRQoL of families. The descriptive data analysis, bivariate logistics regression, and multiple logistics regression was made with the SPSS software (IC 95%, p<0,05). In most of the studied subjects the mother was the main guardian of the patient (78.8%), the monthly income of 51.9% of the families was 1 minimum wage salary and 65,4% shared their home with up to 4 people. From the children/adolescents 88,5% were being treated for leukemia and 42,3% were female. The multiple analysis that when the mother was the person responsible for the patient there was a chance 13,9 times higher of a greater negative impact to the HRQoL when compared to when the guardian was a different person (OR=13,89; 95%IC: 1,39-138,92; p=0,025). Other independent variables where not associated with the impact on the HRQoL of families. Considering the parents/guardians proxy-report on the parental function, the biggest negative impact was related to worry (mean=46,2; SD±25,56). The family function domains "Daily Activities" and "Family Relationships" had means of 64,4 (SD±36,60) and 84,4 (SD±25,25) respectively, exhibiting a greater impairment in the daily activities than in relationships. It is concluded that childhood cancer and its treatment affect the family's HRQoL. When the mother is primarily responsible for the child/adolescent with cancer, she is more likely to perceive the negative impact that the disease and its treatment can bring to the family nucleus.

Ototoxicidad en pacientes oncológicos: experiencia y propuesta de un protocolo de vigilancia / Ototoxicity in cancer survivors: experience and proposal of a surveillance protocol

Introducción: La ototoxicidad se presenta en diversos porcentajes según estudios tras el tratamiento con quimioterapia basada en platino y/o radioterapia craneal. El objetivo es mostrar nuestra experiencia en la monitorización de la ototoxicidad. Material y métodos: Se realizó una revisión del 1999 al 2019 en el registro de pacientes oncológicos pediátricos de nuestro hospital y remitidos a la Unidad de Hipoacusia Infantil. Resultados: 46 pacientes fueron remitidos a nuestra unidad. 41 pacientes recibieron platinos como parte de su tratamiento, 17 pacientes fueron sometidos a una intervención neuroquirúrgica y 18 pacientes recibieron radioterapia craneal. A todos se les realizó una anamnesis y otoscopia, y la monitorización se llevó a cabo con una audiometría tono-verbal y/o productos de distorsión. Se objetivó una hipoacusia como secuela del tratamiento en ocho pacientes (21,05% de los pacientes remitidos para seguimiento audiológico). Fue imposible determinar la situación audiológica al finalizar el tratamiento en ocho pacientes. La adaptación audioprotésica fue necesaria en dos pacientes. En la coordinación con Oncología Pediátrica, se consideró oportuno el cambio de cisplatino por carboplatino por ototoxicidad importante durante el tratamiento en un único paciente. Conclusión: Es imprescindible una adecuada coordinación con Oncología Pediátrica para realizar una vigilancia activa de la ototoxicidad y modificar, si es posible, la dosificación o el tipo de quimioterápico en caso de verse afectada la audición. En nuestra experiencia, y siguiendo las recomendaciones actuales, realizamos una valoración pretratamiento, una monitorización durante el tratamiento, al finalizarlo y después de forma anual por el riesgo de desarrollo diferido de una hipoacusia.

Introduction: Ototoxicity occurs in different percentages in patients after treatment with platinum-based chemotherapy or cranial radiation therapy. The aim of this study was to present experience in ototoxicity monitoring. Material and methods: A review was made of the registry of paediatric cancer patients referred to the Children's Hearing Loss Unit from 1999 to 2019. Results: Of the 46 patients referred to this unit, 41 had received platinum as part of their treatment, 17 patients underwent neurosurgery, and 18 patients received cranial radiation therapy. An anamnesis and otoscopy were performed on all of them, and the monitoring was carried out with tone-verbal audiometry and/or distortion products. Hearing loss was observed in eight patients (21.05% of patients referred for audiological follow-up) as a consequence of the treatment. It was impossible to determine the audiological situation in eight patients at the end of treatment. Hearing aid adaption was necessary in two patients. In coordination with Paediatric Oncology, a change from cisplatin to carboplatin due to bilateral grade two ototoxicity was considered appropriate during treatment in one patient. Conclusion: Adequate coordination with Paediatric Oncology is essential to carry out active surveillance for ototoxicity and to modify, if possible, the dosage or type of chemotherapy in case hearing is affected. In our experience, and following current recommendations, a pre-treatment assessment is usually performed, as well as monitoring during treatment, at the end of treatment, and annually thereafter due to the risk of a later development of hearing loss.
