ABSTRACT
El cáncer causa millones de muertes a nivel mundial por lo que su registro es fundamental, existiendo registros clínicos, hospitalarios y poblacionales. Estos últimos son el estándar de oro para la información sobre incidencia y supervivencia de cáncer en una región definida. En Chile se cuenta con cinco registros poblacionales ubicados en ciertas zonas del país. El Registro Nacional del Cáncer chileno surge como un desafío para conformar una herramienta transversal a los tres tipos de registro con la finalidad de, al menos, conocer la cantidad de casos por tipo de cáncer. Su diseño implicó un despliegue de acciones orientadas a lograr consensos entre diversos actores respecto de la información, validación y eventos necesarios de registrar. Se identificaron cuatro etapas en el proceso de atención y el registro: sospecha de diagnóstico, confirmación morfológica (biopsia), resolución clínica (comité oncológico incluyendo la indicación de tratamiento), tratamiento y seguimiento oncológico. A su vez, el desarrollo de la plataforma (años 2018 a 2021) implicó levantamiento de información y acuerdos sobre los requerimientos para el co-diseño del registro, incluyendo un exitoso pilotaje con más de 20 establecimientos de salud del sector público y privado con registro de cerca de 7500 casos de cáncer. El despliegue y uso del Registro Nacional de Cáncer a nivel nacional depende de la autoridad sanitaria. Se trata de un sistema de información que recolecta, almacena, procesa y analiza de forma continua y sistemática datos sobre todos los casos y tipos de cánceres que ocurren en el país. En este trabajo se presenta el diseño y desarrollo de la herramienta, los desafíos abordados, sus fortalezas y debilidades.
Cancer causes millions of deaths worldwide, making its registration essential. There are clinical, hospital, and population-based registries in place. The latter is the gold standard for information on cancer incidence and survival in a defined region. Chile has five population-based registries located in specific areas of the country. The Chilean National Cancer Registry emerged with the challenge of creating a tool encompassing all three types of registries to identify the number of cancer cases by type. Its design involved a series of actions to achieve consensus among various actors regarding information, validation, and events to be registered. Four stages were identified in the care and registration process: suspected diagnosis, morphological confirmation (biopsy), clinical resolution (oncology committee, including treatment recommendations), treatment, and oncological follow-up. The platform's development (from 2018 to 2021) involved gathering information and agreements on the requirements for co-designing the registry, including a successful pilot program with over 20 public and private healthcare facilities that recorded nearly 7500 cancer cases. The deployment and use of the National Cancer Registry at a national level depends on the healthcare authority. It is an information system that continuously and systematically collects, stores, processes, and analyzes data on all cancer cases and types occurring in the country. This work presents the design and development of the tool, the challenges addressed, as well as its strengths and weaknesses.

γδ T cells are a kind of innate immune T cell. They have not attracted sufficient attention because they account for only a small proportion of all immune cells, and many basic factors related to these cells remain unclear. However, in recent years, with the rapid development of tumor immunotherapy, γδ T cells have attracted increasing attention because of their ability to exert cytotoxic effects on most tumor cells without major histocompatibility complex (MHC) restriction. An increasing number of basic studies have focused on the development, antigen recognition, activation, and antitumor immune response of γδ T cells. Additionally, γδ T cell-based immunotherapeutic strategies are being developed, and the number of clinical trials investigating such strategies is increasing. This review mainly summarizes the progress of basic research and the clinical application of γδ T cells in tumor immunotherapy to provide a theoretical basis for further the development of γδ T cell-based strategies in the future.

Abstract Objective: to analyze the meaning attributed by parents to the extended and permanent survival of childhood cancer. Method: qualitative narrative inquiry, developed with parents of adolescents and young adults who survived childhood cancer. Recruitment and data collection involved virtual and in-person approaches. The data were collected through semi-structured interviews. Data were analyzed according to reflective thematic analysis. Results: a total of ten parents were included in the study. Two thematic narrative syntheses were constructed: "Times of war"; and "Time of uncertain peace", with their respective sub-themes. The cancer diagnosis marks the beginning of times of war in the parents' lives. They experience cancer treatment as "highs and lows" with potential threats to their children's lives. After that, "Time of uncertain peace" are reached, and the balance of the family unit is reestablished. However, the fear of recurrence makes the family peace uncertain, and its maintenance requires constant vigilance and attention to the signs and symptoms of a possible new battle. Conclusion: the results highlight the experience of being a parent of a childhood cancer survivor and can be applied to develop models of care centered on the survivors' family.

Resumen Desde la primera publicación de la declaración de consenso sobre pautas de ejercicio para personas con cáncer, de la asociación Ejercicio y Ciencias del Deporte - Australia (ESSA, Exercise and Sports Science Australia), ha ocurrido un crecimiento exponencial en las investigaciones que evalúan el papel del ejercicio antes, durante y después del tratamiento del cáncer. El propósito de este reporte es utilizar la evidencia científica actual, junto a la experiencia clínica y los principios de las ciencias del ejercicio, para poner al día la declaración de consenso de ESSA sobre la prescripción de ejercicio específica para el cáncer. En esta declaración de consenso se reporta un resumen de los beneficios alcanzados mediante el ejercicio luego de un diagnóstico de cáncer, así como las fortalezas y limitaciones de la evidencia acumulada. Se propone, entonces, un marco de prescripción del ejercicio para permitir la aplicación de consideraciones específicas para el cáncer en la individualización, especificidad, seguridad, factibilidad y progresión del ejercicio para toda clase de pacientes. Se ofrecen consideraciones adicionales específicas para la prescripción del ejercicio cuando hay presencia de enfermedades hematológicas, osteomusculares, sistémicas, cardiovasculares, linfáticas, gastrointestinales, genitourinarias y neurológicas y preocupaciones relacionadas con su tratamiento, así como la presencia crónica de comorbilidades. Además, se identifican y comentan temas prácticos específicos y barreras que deben tomarse en cuenta para la prescripción del ejercicio. Si bien es cierto que el ejercicio multimodal de intensidad moderada a intensa será apropiado para la mayoría, no hay una prescripción establecida ni una dosificación semanal, que se puedan considerar basadas en la evidencia, para todos los pacientes de cáncer. Es necesaria una prescripción del ejercicio dirigida específicamente a esta población, que asegure el mayor beneficio (conforme lo defina cada paciente) a corto y largo plazo, con un bajo riesgo de perjuicio.
Abstract Objectives: Since Exercise and Sports Science Australia (ESSA) first published its position statement on exercise guidelines for people with cancer, there has been exponential growth in research evaluating the role of exercise pre-, during and post-cancer treatment. Design and Methods: The purpose of this report is to use the current scientific evidence, alongside clinical experience and exercise science principles to update ESSA's position statement on cancer-specific exercise prescription. Results: Reported in this position statement is a summary of the benefits accrued through exercise following a cancer diagnosis and the strengths and limitations of this evidence-base. An exercise prescription framework is then proposed to enable the application of cancer-specific considerations for individualisation, specificity, safety, feasibility and progression of exercise for all patients. Additional specific exercise prescription considerations are provided for the presence of haematological, musculoskeletal, systemic, cardiovascular, lymphatic, gastrointestinal, genitourinary and neurological disease- and treatment-related concerns, as well as presence of co-morbid chronic disease. Further, we also identify and discuss cancer-specific pragmatic issues and barriers requiring consideration for exercise prescription. Conclusions: While for the majority, multimodal, moderate to high intensity exercise will be appropriate, there is no set prescription and total weekly dosage that would be considered evidence-based for all cancer patients. Targeted exercise prescription, which includes the provision of behaviour change advice and support, is needed to ensure greatest benefit (as defined by the patient) in the short and longer term, with low risk of harm.
Resumo Desde a primeira publicação da declaração de consenso da Organização de Ciências do Exercício e do Esporte - Austrália ((ESSA, Exercise and Sports Science Australia) sobre diretrizes de exercícios para pessoas com câncer, tem ocorrido um crescimento exponencial nas pesquisas que avaliam o papel dos exercícios antes, durante e depois do tratamento do câncer. O objetivo deste relatório é usar as evidências científicas atuais com a experiência clínica e os princípios da ciência do exercício, para atualizar a declaração de consenso da ESSA sobre a prescrição de exercícios específica para o câncer. Esta declaração de consenso relata um resumo dos benefícios obtidos por meio de exercícios após o diagnóstico de câncer, bem como os pontos fortes e as limitações da evidência acumulada. Assim, propõe-se uma estrutura de prescrição de exercícios para permitir a aplicação de considerações específicas para o câncer na individualização, especificidade, segurança, viabilidade e progressão do exercício para todas as classes de pacientes. Considerações adicionais específicas para a prescrição de exercícios são fornecidas quando há doenças hematológicas, osteomusculares, sistêmicas, cardiovasculares, linfáticas, gastrointestinais, geniturinárias, neurológicas e preocupações relacionadas ao seu tratamento, bem como a presença crônica de comorbidades. Além disso, questões práticas específicas e barreiras à prescrição de exercícios são identificadas e discutidas. Embora seja verdade que o exercício multimodal de intensidade moderada a vigorosa seja apropriado para a maioria, não há uma prescrição definida ou dosagem semanal que possa ser considerada baseada em evidências para todos os pacientes com câncer. Há uma necessidade de prescrição de exercícios especificamente direcionada a essa população, garantindo o maior benefício (conforme definido pelo paciente individual) em curto e longo prazos, com baixo risco de danos.

Children with cancer commonly present oral health impairments due to lack of orientation about oral hygiene, which should be directed to caregivers since they are essential in this process. We developed and validated a guideline directed to caregivers for oral hygiene of children with cancer. This exploratory methodological study developed an educational guideline in three stages: analysis of oral health of children attended at the oncology service; literature review and development of the guideline for oral hygiene; semantic, appearance, and content validation by dentists, education professionals, and the target population. We used the Educational Content Validation Instrument in Health, and agreements of ≥ 80 % among evaluators were considered to maintain or modify the assessed items. Professionals and caregivers were mostly female; the latter were predominantly mothers with low educational level from inland areas of Pernambuco state (Brazil). Most professionals had more than ten years of experience in pediatric dentistry. Agreement was > 80 % in all items. The content of the guideline for oral hygiene was valid and relevant to be used in children with cancer.
Los niños con cáncer comúnmente presentan afecciones en la salud bucal por falta de orientación sobre la higiene bucal, la cual debe ser dirigida a los cuidadores ya que son fundamentales en este proceso. Desarrollamos y validamos una guía dirigida a cuidadores para la higiene bucal de niños con cáncer. Este estudio metodológico exploratorio desarrolló una directriz educativa en tres etapas: análisis de la salud bucal de los niños atendidos en el servicio de oncología; revisión de la literatura y desarrollo de la guía para la higiene oral; validación semántica, de apariencia y de contenido por parte de odontólogos, profesionales de la educación y población objetivo. Se utilizó el Instrumento de Validación de Contenido Educativo en Salud, y se consideraron acuerdos ≥ 80 % entre evaluadores para mantener o modificar los ítems evaluados. Los profesionales y cuidadores eran en su mayoría mujeres; estas últimas eran predominantemente madres con bajo nivel educativo del interior del estado de Pernambuco (Brasil). La mayoría de los profesionales tenían más de diez años de experiencia en odontopediatría. La concordancia fue > 80 % en todos los ítems. El contenido de la guía de higiene oral fue válido y pertinente para ser utilizado en niños con cáncer.

Introducción: El uso clínico de la ozonoterapia se incrementa cada día. Abarca disímiles especialidades médicas como la oncología. En Cuba las investigaciones que evalúan el empleo de la ozonoterapia en pacientes con cáncer son escasas, se precisan estudios científicos que demuestren su eficacia clínica. Objetivo: Explicar los mecanismos farmacológicos y bioquímicos de la ozonoterapia y su uso en el cáncer como terapia complementaria. Métodos: Se consultaron bases de datos disponibles a través de la red de Infomed. Se utilizaron como palabras clave: cáncer, ozonoterapia y estrés oxidativo. Se seleccionaron artículos originales y de revisión sistemáticos de los últimos diez años que evaluaron la utilización de la ozonoterapia en el tratamiento del cáncer. Resultados: El cáncer es per se una enfermedad inductora de estrés oxidativo. La ozonoterapia respalda su utilización como una terapia adyuvante mediante el preacondicionamiento oxidativo que estimula los sistemas antioxidantes de la célula contra la acción de los radicales libres. Así, se logra neutralizar la acción nociva del estrés oxidativo. El ozono incrementa la eficacia de la radio - quimioterapia y ayuda a reducir los efectos secundarios de estos tratamientos al activar los sistemas antioxidantes de la célula. La ozonoterapia se caracteriza por la simplicidad de su aplicación, bajos costos, alta efectividad y prácticamente ausencia de efectos colaterales en comparación con otros tratamientos adyuvantes. Conclusiones: El uso de la ozonoterapia en oncología como una terapia adyuvante representó un recurso terapéutico de gran valor dado por su perfil de efectividad y seguridad. Su uso podría extenderse para disminuir los efectos secundarios y mejorar la calidad de vida de los pacientes(AU)
Introduction: The clinical use of ozone therapy is increasing every day worldwide and it covers different medical specialties, including oncology. However, in Cuba, the investigations that evaluate the use of ozone therapy in cancer patients are scarce, so scientific studies are needed to demonstrate its clinical efficacy. Objective: To explain the pharmacological and biochemical mechanisms of ozone therapy and its use in cancer as a complementary therapy. Methods: Databases available through Infomed Network were consulted. Key words used were cancer, ozone therapy and oxidative stress. Original and systematic review articles from the last ten years that evaluated the use of ozone therapy in the treatment of cancer were selected. Results: Cancer is, as such, a disease that induces oxidative stress. Ozone therapy supports its use as an adjuvant therapy through oxidative pre-conditioning that stimulates the cell's antioxidant systems against the action of free radicals. Thus, it is possible to neutralize the harmful action of oxidative stress. Ozone increases the efficacy of radio-chemotherapy and helps reducing the side effects of these treatments by activating the cell's antioxidant systems. Ozone therapy is characterized by the simplicity of its application, low costs, high effectiveness and with practically no side effects, compared to other adjuvant treatments. Conclusions: The use of ozone therapy in oncology as an adjuvant therapy represented a therapeutic resource of great value given its effectiveness and safety profile. Its use could be extended to improve tissue oxygenation and thus enhance the efficacy of radiochemotherapy, reducing side effects and improving the patients's quality of life(AU)

Cancer related anemia (CRA) is a common side effect in patients with tumors, the incidence of which is related to tumor type, treatment regimen, the duration of chemotherapy, etc. The pathogenesis of CRA has not been fully defined. CRA may lead to chemotherapy dose reduction or may even delay chemotherapy. Patients with CRA require red blood cell transfusion, thus increasing the treatment cost, reducing the efficiency of chemotherapy and the patient's quality of life, and shortening the survival time. The main treatments of CRA include red blood cell transfusion, iron supplements, erythropoietin, and so on. Based on recent literature and clinical studies, the expert committee of the China Anti-Cancer Association drew up the consensus on the diagnosis and treatment of anemia related to tumor in China (2023 edition). The 2023 consensus incorporates the latest evidence-based medicine evidence and Traditional Chinese Medicine related content and aims to provide more reliable diagnosis and treatment plans for Chinese oncologists to help improve CRA and the quality of life in patients with cancer.

Tumors in which the microenvironment is characterized by lack of immune cell infiltration are referred as "cold tumors" and typically exhibit low responsiveness to immune therapy. Targeting the factors contributing to "cold tumors" formation and converting them into "hot tumors" is a novel strategy for improving the efficacy of immunotherapy. Adenosine, a hydrolysis product of ATP, accumulates with a significantly higher concentration in the tumor microenvironments compared with normal tissue and exerts inhibitory effects on tumor-specific adaptive immunity. Tumor cells, dendritic cells, macrophages, and T cells express abundant adenosine receptors on their surfaces. The binding of adenosine to these receptors initiates downstream signaling pathways that suppress tumor antigen presentation and immune cell activation, consequently dampening adaptive immune responses against tumors. Adenosine down-regulates the expression of major histocompatibility complex Ⅱ and co-stimulatory factors on dendritic cells and macrophages, thereby inhibiting antigen presentation to T cells. Adenosine also inhibits ligand-receptor binding and transmembrane signaling on T cells, concomitantly suppressing the secretion of anti-tumor cytokines and impairing T cell activation. Furthermore, adenosine hinders effector T cell trafficking to tumor sites and infiltration by inhibiting chemokine secretion and KCa3.1 channels. Additionally, adenosine promotes the secretion of immunosuppressive cytokines, increases immune checkpoint protein expression, and enhances the activity of immunosuppressive cells, collectively curbing cytotoxic T cell-mediated tumor cell killing. Given the immunosuppressive role of adenosine in adaptive antitumor immunity, several inhibitors targeting adenosine generation or adenosine receptor blockade are currently in preclinical or clinical development with the aim of enhancing the effectiveness of immunotherapies. This review provides an overview of the inhibitory effects of adenosine on adaptive antitumor immunity, elucidate the molecular mechanisms involved, and summarizes the latest advances in application of adenosine inhibition strategies for antitumor immunotherapy.

NK cell immunotherapy is a promising antitumor therapeutic modality after the development of T cell immunotherapy. Structural modification of NK cells with biomaterials may provide a precise, efficient, and low-cost strategy to enhance NK cell immunotherapy. The biomaterial modification of NK cells can be divided into two strategies: surface engineering with biomaterials and intracellular modification. The surface engineering strategies include hydrophobic interaction of lipids, receptor-ligand interaction between membrane proteins, covalent binding to amino acid residues, click reaction and electrostatic interaction. The intracellular modification strategies are based on manipulation by nanotechnology using membranous materials from various sources of NK cells (such as exosome, vesicle and cytomembranes). Finally, the biomaterials-based strategies regulate the recruitment, recognition and cytotoxicity of NK cells in the solid tumor site in situ to boost the activity of NK cells in the tumor. This article reviews the recent research progress in enhancing NK cell therapy based on biomaterial modification, to provide a reference for further researches on engineering NK cell therapy with biomaterials.

Objective This consensus aims to provide evidence-based recommendations on common questions in the diagnosis and treatment of acute respiratory failure (ARF) for critically ill cancer patients.Methods We developed six clinical questions using the PICO (Population, Intervention, Comparison, and Outcome) principle in diagnosis and treatment for critical ill cancer patients with ARF. Based on literature searching and meta-analyses, recommendations were devised. The GRADE (Grading of Recommendation Assessment, Development and Evaluation) method was applied to each question to reach consensus in the expert panel. Results The panel makes strong recommendations in favor of (1) metagenomic next-generation sequencing (mNGS) tests may aid clinicians in rapid diagnosis in critically ill cancer patients suspected of pulmonary infections; (2) extracorporeal membrane oxygenation (ECMO) therapy should not be used as a routine rescue therapy for acute respiratory distress syndrome in critically ill cancer patients but may benefit highly selected patients after multi-disciplinary consultations; (3) cancer patients who have received immune checkpoint inhibitor therapy have an increased incidence of pneumonitis compared with standard chemotherapy; (4) critically ill cancer patients who are on invasive mechanical ventilation and estimated to be extubated after 14 days may benefit from early tracheotomy; and (5) high-flow nasal oxygen and noninvasive ventilation therapy can be used as a first-line oxygen strategy for critically ill cancer patients with ARFs. A weak recommendation is: (6) for critically ill cancer patients with ARF caused by tumor compression, urgent chemotherapy may be considered as a rescue therapy only in patients determined to be potentially sensitive to the anticancer therapy after multidisciplinary consultations. Conclusions The recommendations based on the available evidence can guide diagnosis and treatment in critically ill cancer patients with acute respiratory failure and improve outcomes.

OBJECTIVE@#To investigate the distribution of irregular blood group antibodies in patients with malignant tumors, and to analyze the relationship between it and efficacy of blood transfusion in patients.@*METHODS@#5 600 patients with malignant tumors treated in Shanxi Bethune Hospital from January 2019 to December 2021 were selected as the research subjects. All patients received blood transfusion, and cross matching test was conducted before blood transfusion, irregular antibody results of patients were tested; the irregular distribution of blood group antibodies was observed, and the relationship between it and efficacy of blood transfusion in patients was analyzed.@*RESULTS@#Among 5 600 patients with malignant tumors, 96 cases were positive for irregular antibody, and the positive rate was 1.71%; the main blood group systems involved in the irregular antibody positive of 96 patients with malignant tumors were RH, MNSs and Duffy system, among which Rh blood group was the most common, and the proportion of anti-E was the highest; among the malignant tumor patients with positive blood group irregular antibody, the proportion of female was higher than that of male; the proportion of patients aged >60 years was the highest, followed by patients aged >40 and ≤50 years, and the proportion of patients aged 18-30 years was the lowest; the patients with positive blood group irregular antibody were mainly in blood system (including lymphoma), digestive system, reproductive and urinary system; the positive rate of irregular antibody of patients in the ineffective group was higher than that of patients in the effective group, the difference was statistically significant (P<0.05). Logistic regression analysis results showed that, irregular antibody positive was a risk factor for ineffective blood transfusion in patients with malignant tumor (OR>1, P<0.05).@*CONCLUSION@#The irregular blood group antibody positive of patients with malignant tumor are mostly female, and the proportion of patients aged >60 is the highest, which is mainly distributed in malignant tumors of blood system, digestive system and urogenital system, and the positive blood group irregular antibody is related to the efficacy of blood transfusion in patients.

Knowledge of an underlying genetic predisposition to cancer allows the use of personalised prognostic, preventive and therapeutic strategies for the patient and carries clinical implications for family members. Despite great progress, we identified six challenging areas in the management of patients with hereditary cancer predisposition syndromes and suggest recommendations to aid in their resolution. These include the potential for finding unexpected germline variants through somatic tumour testing, optimal risk management of patients with hereditary conditions involving moderate-penetrance genes, role of polygenic risk score in an under-represented Asian population, management of variants of uncertain significance, clinical trials in patients with germline pathogenic variants and technology in genetic counselling. Addressing these barriers will aid the next step forward in precision medicine in Singapore. All stakeholders in healthcare should be empowered with genetic knowledge to fully leverage the potential of novel genomic insights and implement them to provide better care for our patients.

There is a commonality between jingjin (muscle region of meridian) and the fascial network for coordinating the balance in the body. The occurrence and the progression of tumor may disrupt the overall coordination between the fascial network and jingjin directly or indirectly, thereby, the impairment of this coordination may result in cancer pain. Rooted on the theory of overall balance of the fascial network, and combined with understanding of pain in jingjin theory, professor HUANG Jin-chang emphasizes the importance of "relaxing the knot" in treatment of cancer pain. It is recommended to select the fascia reaction point as the target point, in accordance with the principle of balance adjustment and apply various acupuncture and moxibustion therapies, such as Fu's subcutaneous needling, small-needle scalpel therapy, fire needling, and moxibustion.

Cell-mediated immune response is an important part of machinery in maintaining the body's homeostasis. After the innate immune system selectively activates the adaptive immune system, the cell-mediated immunity exerts its killing and clearance functions. Therefore, evaluating the level of cell-mediated immune response is crucial in the diagnosis and treatment of cancer, monitoring the immune status after organ transplantation, diagnosing and preventing viral diseases, and evaluating the effectiveness of vaccines and other areas. From the initial overall assessment of the immune effects in vivo to the precise detection of the number and function of multiple immune cells, the evaluation methods of cell-mediated immune response have greatly advanced. However, cell-mediated immune response involves multiple levels in the body, and it's difficult to choose the numerous detection methods available. The article systematically compares the evaluation methods of cell-mediated immune response at four different levels: the organism, the tissue and organ, the immune cells and the immune molecules, with the aim to facilitate the applications of related technologies.
