RESUMEN
Introdução: O câncer de pulmão é uma doença grave, sendo a segunda maior causa de morte em todo o mundo, entretanto, em alguns países desenvolvidos, tornou-se já a primeira causa de morte. Cerca de 90% dos casos de neoplasia pulmonares são causados pela inalação da fumaça do cigarro. Objetivo: Correlacionar a prevalência de tabagismo e morbimortalidade por câncer de pulmão nos estados brasileiros, além de demonstrar a associação destes com sexo e faixa etária. Métodos: Estudo de caráter ecológico acerca da prevalência de tabagismo e morbimortalidade por câncer de pulmão nos estados brasileiros, nos períodos de 2013 e 2019, dividida por sexo e faixa etária. Foram utilizados bancos de coleta de dados como o Tabnet e Pesquisa Nacional de Saúde. Resultados: As maiores taxas de mortalidade e internações hospitalares foram do público masculino, em 2013, com taxa de 2,7 e 10, respectivamente, e em 2019 com 3,3 e 11,9, respectivamente. Ademais, a maior prevalência de tabagismo foi encontrada nos homens; entretanto seu índice tem caído, enquanto a quantidade de mulheres tabagistas tem aumentado. A Região Sul demonstrou maiores números de mortalidade em ambos os períodos estudados, com taxas de 4,9 e 5,8 por 100 mil habitantes, e morbidade hospitalar com 19,9 e 23,5 por 100 mil habitantes. Já a Região Norte se configurou com as menores prevalências: em 2013 apresentou taxa de óbito por câncer de pulmão de 1,0 e morbidade hospitalar de 3,5/100 mil habitantes, em 2019 apresentou taxa de mortalidade de 4,6 e internações de 1,6/100 mil habitantes. Os coeficientes de correlação de morbidade hospitalar e prevalência de tabagismo foram R2=0,0628, r=0,251 e p=0,042, enquanto os de mortalidade e prevalência de tabagismo foram R2=0,0337, r=0,183 e p=0,140. Conclusões: Na presente pesquisa, pode-se inferir que houve associação positiva na comparação entre taxa de morbidade hospitalar e prevalência de tabagismo; em contrapartida, não foi possível observar associação positiva na correlação da taxa de mortalidade por câncer de pulmão e prevalência de tabagismo.
Introduction: Lung cancer is a serious disease, being the second leading cause of death worldwide. Moreover, in some developed countries, it has already become the leading cause of death. About 90% of lung cancer cases are caused by cigarette smoking. Objective: To correlate the prevalence of smoking and lung cancer morbidity and mortality in Brazilian states, and to demonstrate their association with sex and age group as well. Methods: An ecological study on the prevalence of smoking and lung cancer morbidity and mortality in Brazilian states between 2013 and 2019, divided by sex and age group. The data collection databases Tabnet and National Health Survey were used. Results: The highest rates of mortality and hospital admissions were among men, in 2013 with a rate of 2.7 and 10, respectively, and in 2019 with 3.3 and 11.9, respectively. In addition, the highest prevalence of smoking was found in men, but this rate has fallen, while the number of women smokers has increased. The South region showed higher mortality rates in both periods studied, with rates of 4.9 and 5.8 per 100,000 inhabitants, and hospital morbidity with 19.9 and 23.5 per 100,000 inhabitants. The North region had the lowest prevalence, where in 2013, it had a death rate from lung cancer of 1.0 and hospital morbidity of 3.5/100 thousand inhabitants, and where in 2019, it had a mortality rate of 4.6 and hospitalizations of 1.6/100 thousand inhabitants. The correlation coefficients for hospital morbidity and smoking prevalence were R2=0.0628, r=0.251 and p=0.042, while for mortality and smoking prevalence, these were R2=0.0337, r=0.183 and p=0.140. Conclusions: In the present study, it can be inferred that there was a positive association between hospital morbidity rate and prevalence of smoking, while it was not possible to observe a correlation between lung cancer mortality rate and prevalence of smoking.
Introducción: El cáncer de pulmón es una enfermedad grave, siendo la segunda causa de muerte en todo el mundo, sin embargo, en algunos países desarrollados, ya se ha convertido en la primera causa de muerte. Alrededor del 90% de los casos de neoplasias pulmonares están causados por la inhalación del humo del cigarrillo. Objetivo: Correlacionar la prevalencia de tabaquismo y la morbimortalidad por cáncer de pulmón en los estados brasileños, además de demostrar la asociación de estos con el género y el grupo de edad. Métodos: estudio ecológico sobre la prevalencia de tabaquismo y morbimortalidad por cáncer de pulmón en los estados brasileños, dentro de los períodos 2013 y 2019, divididos por sexo y grupo de edad. Se utilizaron bancos de recogida de datos como Tabnet y la Encuesta Nacional de Salud. Resultados: las mayores tasas de mortalidad e ingresos hospitalarios se dieron en el público masculino, en 2013 con una tasa de 2,7 y 10, respectivamente, y en 2019 con 3,3 y 11,9, respectivamente. Además, la mayor prevalencia del tabaquismo se encontró en los hombres, sin embargo, su tasa ha disminuido, mientras que la cantidad de mujeres fumadoras ha aumentado. La región Sur presentó cifras más altas de mortalidad en ambos periodos estudiados, con tasas de 4,9 y 5,8 por 100.000 habitantes, y de morbilidad hospitalaria con 19,9 y 23,5 por 100.000 habitantes. Mientras que la región Norte se configuró con las prevalencias más bajas, en 2013 presentó una tasa de mortalidad por cáncer de pulmón de 1,0 y una morbilidad hospitalaria de 3,5/100.000 habitantes, en 2019 presentó una tasa de mortalidad de 4,6 y hospitalizaciones de 1,6/100.000 habitantes. Los coeficientes de correlación para la morbilidad hospitalaria y la prevalencia del tabaquismo fueron R2=0,0628, r=0,251 y p=0,042, mientras que para la mortalidad y la prevalencia del tabaquismo fueron R2=0,0337, r=0,183 y p=0,140. Conclusiones: En la presente investigación se puede inferir que existe una asociación positiva en la comparación entre la tasa de morbilidad hospitalaria y la prevalencia de tabagismo, en contrapartida, no fue posible observar una asociación positiva en la correlación de la tasa de mortalidad por cáncer de pulmón y la prevalencia de tabagismo.

O câncer, frequentemente relacionado ao envelhecimento, impulsiona pacientes a buscarem tratamento hospitalar ou métodos alternativos, como plantas medicinais. Este estudo visou avaliar os perfis sociodemográfico e clínico e o consumo de plantas para fins medicinais entre pacientes idosos em tratamento oncológico no Hospital Araújo Jorge (HAJ). Dados de 55 pacientes foram analisados, abrangendo informações sociodemográficas, tipos de câncer, tratamento, a utilização de plantas medicinais, o objetivo de uso, as fontes de informações sobre plantas e se notaram alguma reação adversa após o consumo. A faixa etária mais encontrada foi 61 a 70 anos (67,27%), a maioria dos pacientes eram homens (63,64%), com ensino fundamental incompleto (32,73%), casados (56,36%) e que moram no interior de Goiás (43,64%). Quanto ao tratamento, a maioria realizava quimioterapia (40,00%) e o câncer gástrico foi mais relatado (14,54%). Sobre o uso de plantas medicinais, a maioria relatou simpatizar com o consumo (58,18%), e acredita em sua segurança devido à origem natural (59,37%). Informações sobre o uso de plantas medicinais eram obtidas com amigos, vizinhos e familiares (21,81%). Ao relatar sobre o consumo de plantas medicinais durante a quimioterapia, a maioria não percebeu nenhum efeito (40,63%). Foram citadas 17 plantas, que eram utilizadas no tratamento anticâncer (29,00%) e preparadas como infusões (18,75%) pelo uso das folhas frescas (60,00%), principalmente para uso interno (46,87%). Diante disso, a atenção farmacêutica se mostra vital para guiar pacientes nas práticas seguras e eficazes de consumo. Isso inclui direcionar sobre doses adequadas, efeitos colaterais e interações, garantindo bem-estar e prevenindo riscos à saúde.
Cancer, which is often related to ageing, drives patients to seek hospital treatment or alternative methods such as medicinal plants. This study aimed to evaluate the sociodemographic and clinical profile and the consumption of plants for medicinal purposes among elderly patients undergoing cancer treatment at the Araújo Jorge Hospital (AJH). Data from 55 patients was analyzed, covering sociodemographic information, types of cancer, treatment, the use of medicinal plants, the purpose of use, the source of information about plants and whether they noticed any adverse reactions after consumption. The most common age group was 61 to 70 years (67.27%), the majority of patients were men (63.64%), had incomplete primary education (32.73%), were married (56.36%) and lived in the interior of Goiás (43.63%). With regard to treatment, the majority were undergoing chemotherapy (40,00%) and gastric cancer was the most frequently reported (14.54%). With regard to the use of medicinal plants, the majority were sympathetic to their consumption (58.18%) and believed them to be safe due to their natural origin (59.37%). Information on the use of medicinal plants was obtained from friends, neighbors and family members (21.81%). When reporting on the consumption of medicinal plants during chemotherapy, the majority did not notice any effect (40.63%). Seventeen plants were mentioned, which were used for anticancer treatment (29,00%) and prepared as infusions (18.75%) with fresh leaves (60,00%), mainly for internal use (46.87%). In view of this, pharmaceutical care is vital to guide patients in safe and effective consumption practices. This includes guidance on appropriate doses, side effects and interactions, ensuring well-being and preventing health risks.

A instabilidade de microssatélites é um fenômeno genético caracterizado pela alteração na repetição de sequências de nucleotídeos conhecidas como microssatélites. Esta instabilidade pode ocorrer devido a defeitos nos genes reparadores de DNA, como os genes MLH1, MSH2, MSH6 e PMS2. A inflamação crônica tem sido associada ao desenvolvimento do câncer colorretal. Os genes da instabilidade de microssatélites estão envolvidos na regulação da resposta inflamatória, podendo influenciar a progressão tumoral. Estudos demonstraram que a presença de instabilidade de microssatélites em tumores colorretais está relacionada a uma maior infiltração de células imunes, como linfócitos T, macrófagos e neutrófilos, que podem modular a resposta inflamatória no microambiente tumoral. O estresse oxidativo é caracterizado pelo desequilíbrio entre a produção de espécies reativas de oxigênio e a capacidade antioxidante do organismo e desempenha um papel importante na carcinogênese. Os genes da instabilidade de microssatélites podem influenciar a resposta ao estresse oxidativo, afetando a capacidade das células tumorais de lidar com o dano oxidativo e promovendo a sobrevivência celular. O objetivo deste trabalho consiste na compreensão dos genes envolvidos na instabilidade de microssatélites no câncer colorretal e como eles contribuem para o desenvolvimento da doença, relacionando com processos inflamatórios e estresse oxidativo nas células tumorais. Justifica-se pela necessidade de compreensão das interconexões entre a instabilidade de microssatélites, inflamação e o estresse oxidativo em pacientes com câncer colorretal.
Microsatellite instability is a genetic phenomenon characterized by changes in the repetition of nucleotide sequences known as microsatellites. This instability may occur due to defects in DNA repair genes, such as the MLH1, MSH2, MSH6 and PMS2 genes. Chronic inflammation has been linked to the development of colorectal cancer. Microsatellite instability genes are involved in regulating the inflammatory response and may influence tumor progression. Studies have shown that the presence of microsatellite instability in colorectal tumors is related to a greater infiltration of immune cells, such as T lymphocytes, macrophages and neutrophils, which can modulate the inflammatory response in the tumor microenvironment. Oxidative stress is characterized by the imbalance between the production of reactive oxygen species and the body's antioxidant capacity and plays an important role in carcinogenesis. Microsatellite instability genes can influence the response to oxidative stress, affecting the ability of tumor cells to deal with oxidative damage and promoting cell survival. The objective of this work is to understand the genes involved in microsatellite instability in colorectal cancer and how they contribute to the development of the disease, relating it to inflammatory processes and oxidative stress in tumor cells. It is justified by the need to understand the interconnections between microsatellite instability, inflammation and oxidative stress in patients with colorectal cancer.

Reportamos el caso de una paciente con un cuadro grave de falla multisistémica en la cual se detectaron cambios cromosómicos masivos en estado de mosaico, que se consideran estarían asociados a la posible patología de fondo: un síndrome linfoproliferativo de Células T. La paciente también presentaba un cuadro de Eritrodermia de causa desconocida instaurado varios años antes, con un declive progresivo de su condición física. El espectro de las manifestaciones clínicas se presenta entonces como un cuadro cutáneo inespecífico paraneoplásico de varios años de evolución y hallazgos de cromoanagénesis en la última fase de un proceso mórbido linfoproliferativo. Las nuevas técnicas de análisis genético permiten obtener datos para aclarar los procesos diagnósticos e identificar una desorganización grave de la información genética que se considera responsable de cambios neoplásicos.

We report the case of a patient with severe multisystemic failure in which massive chromosomal changes in mosaic state were detected, which are considered to be associated with the possible underlying pathology: a T-cell lymphoproliferative syndrome. The patient also presented a case of Erythroderma of unknown cause several years earlier, with a progressive decline in her physical condition. The spectrum of clinical manifestations is then presented as a nonspecific paraneoplastic cutaneous picture of several years of evolution and findings of chromoanagenesis in the last phase of a lymphoproliferative morbid process. The new techniques of genetic analysis make it possible to obtain data to clarify the diagnostic processes and to identify a serious disorganization of the genetic information considered to be responsible for neoplastic changes.

RESUMEN
Introducción: Nuestro trabajo aborda una revisión bibliográfica realizada entre enero de 2019 y septiembre de 2023, se resalta la importancia de los genes BRCA1, BRCA2, AR y PTEN en la patogénesis, pronóstico y tratamiento del cáncer de próstata, especialmente en su forma metastásica resistente a la castración (mCRPC). Los genes BRCA1 y BRCA2 se identifican como marcadores clave para prever la agresividad del cáncer, sugiriendo la necesidad de terapias dirigidas y vigilancia estricta. La adaptabilidad de las células cancerosas y la variabilidad en la expresión del receptor de andrógenos (AR) limitan la efectividad de las terapias centradas únicamente en AR, señalando la importancia de identificar vías alternativas y biomarcadores para un tratamiento más efectivo. La función de PTEN se relaciona directamente con la progresión de la enfermedad, y su alteración sugiere posibles enfoques terapéuticos. Sin embargo, la heterogeneidad de las células cancerosas y la complejidad de las vías moleculares presentan desafíos significativos para el desarrollo de terapias universales. Conclusión: Los hallazgos promueven la investigación futura para confirmar la aplicabilidad de estos genes como biomarcadores y desarrollar estrategias de tratamiento personalizadas en el cáncer de próstata.

Introduction: Our work addresses a literature review conducted between January 2019 and September 2023, the importance of BRCA1, BRCA2, AR and PTEN genes in the pathogenesis, prognosis and treatment of prostate cancer, especially in its metastatic castration-resistant form (mCRPC), is highlighted. BRCA1 and BRCA2 genes are identified as key markers for predicting cancer aggressiveness, suggesting the need for targeted therapies and strict surveillance. The adaptability of cancer cells and variability in androgen receptor (AR) expression limit the effectiveness of therapies focused solely on AR, pointing to the importance of identifying alternative pathways and biomarkers for more effective treatment. PTEN function is directly related to disease progression, and its alteration suggests potential therapeutic approaches. However, the heterogeneity of cancer cells and complexity of molecular pathways present significant challenges to the development of universal therapies. Conclusion: The findings promote future research to confirm the applicability of these genes as biomarkers and to develop personalized treatment strategies in prostate cancer.

RESUMEN
Introducción: La desnutrición es frecuente en el paciente oncológico y se asocia a una menor respuesta a la radioterapia, quimioterapia y un mayor índice de mortalidad. Es sumamente importante identificar aquellos pacientes malnutridos y en riesgo de desnutrición para realizar una intervención nutricional de manera precoz e individualizada. Objetivo: Valorar el estado nutricional y describir la prevalencia de malnutrición en pacientes adultos en tratamiento oncológico, que concurren al Hospital de Día de Oncología del HIGA "Profesor Dr. Luis Güemes", Haedo. Materiales y métodos: Este estudio descriptivo transversal, desarrollado entre los meses de julio del 2021 y mayo de 2022, se realizó en pacientes adultos que asisten al Hospital de Día de Oncología en forma ambulatoria. Para el cribado nutricional se utilizó la herramienta NutriScore y los criterios GLIM para el diagnóstico de desnutrición. Resultados: El tamaño muestral fue de 93 personas. La localización más frecuente fue el cáncer de mama (29%), seguido por pulmón (4%), útero (13%) y, por último, colon (11%). El 23% de los pacientes se encontraban en riesgo nutricional. Al aplicar los criterios GLIM se evidenció una prevalencia de desnutrición del 23%, siendo el 48% moderada y el 52% severa. Por otro lado, solo el 6,5% presentaban bajo peso y el 52,6% presentaba exceso de peso. Conclusiones: La malnutrición es un diagnóstico frecuente en pacientes oncológicos, teniendo importantes repercusiones a nivel de la morbimortalidad, la calidad de vida y los costos sanitarios. Se recomienda realizar detección de riesgo y valoración del estado nutricional en todos los pacientes con diagnóstico oncológico con el objetivo de instaurar un abordaje nutricional precoz y adecuado
Introduction: Malnutrition is common in cancer patients and is associated with a lower response to radiotherapy, chemotherapy and a higher mortality rate. It is extremely important to identify those malnourished patients and at risk of malnutrition to perform a nutritional intervention early and individualized. Objective: To assess the nutritional status and describe the prevalence of malnutrition in adult patients undergoing cancer treatment, who attend the Oncology Day Hospital of the HIGA ''Profesor Dr. Luis Güemes'', Haedo. Materials and methods: This cross-sectional descriptive study developed between the months of July 2021 and May 2022 was carried out in adult patients who attend the Oncology Day Hospital as an outpatient. The NutriScore tool and the GLIM criteria were used for the nutritional assessment. Results: The sample size was 93 people. The most frequent location was breast cancer (29%), followed by lung (4%), uterus (13%) and finally colon (11%). 23% of patients were at nutritional risk. When applying the GLIM criteria, a prevalence of malnutrition of 23% was evident, being 48% moderate and 52% severe. On the other hand, only 6.5% were underweight and 52.6% were overweight. Conclusions: Malnutrition is a frequent diagnosis in cancer patients, having important repercussions in terms of morbidity and mortality, quality of life and health costs. It is recommended to perform risk detection and assessment of nutritional status in all patients with an oncological diagnosis with the aim of establishing an early and appropriate nutritional approach

El cáncer de mama no metastásico es aquel que no se ha diseminado desde el sitio primario. Más del 90 % de las personas que reciben un diagnóstico de cáncer de mama son no metastásicos. La quimioterapia reduce la tasa de mortalidad hasta un 40 %, pero también causa efectos físicos, psicológicos, sexuales y sociales. Por lo tanto, el objetivo fue identificar los cambios en la función sexual causados por la quimioterapia en pacientes con cáncer de mama no metastásico. La quimioterapia incluye cuatro grupos de fármacos: antraciclinas, alquilantes, antimetabolitos y taxanos. Estos provocan la isquemia local y el agotamiento de los folículos primordiales, lo que resulta en una menopausia temprana y cambios fisiológicos que afectan la función física, sexual y psicológica. Se llevó a cabo una revisión de la bibliografía utilizando índices o bases de datos como PubMed, SciELO, Elsevier, así como las revistas The Lancet y Nature. Se incluyeron artículos originales y revisados en inglés y español que se publicaron entre 2019 y 2023. Una de las mejores opciones de tratamiento para el cáncer de mama no metastásico actualmente es la quimioterapia, pero se ha demostrado que provoca una menopausia temprana, alteraciones en las hormonas sexuales y alteraciones en la función sexual
Non-metastatic breast cancer does not spread from the initial site. More than 90 % of people diagnosed with breast cancer are non-metastatic. Chemotherapy reduces the mortality rate by up to 40 %, but it also causes physical, psychological, sexual and social effects. Therefore, we aimed to identify changes in sexual function caused by chemotherapy in patients with non-metastatic breast cancer. Chemotherapy includes four groups of drugs: anthracyclines, alkylating agents, antimetabolites, and taxanes. These cause local ischemia and depletion of primordial follicles, resulting in early menopause and physiological changes that affect physical, sexual and psychological function. A review of the literature was carried out using indexes or databases such as PubMed, SciELO, Elsevier, as well as the journals The Lancet and Nature. Original and peer-reviewed articles in English and Spanish that were published between 2019 and 2023 were included. One of the best treatment options for non-metastatic breast cancer currently is chemotherapy, but it has been shown to cause early menopause, alterations in sex hormones and alterations in sexual functio

Resumo O estudo visa analisar a prevalência de estadiamento avançado ao diagnóstico do câncer do colo do útero e sua associação com indicadores individuais e contextuais socioeconômicos e de oferta de serviços de saúde no Brasil. Estudo transversal, realizado com casos de câncer do colo do útero em mulheres de 18 a 99 anos, no período de 2006 a 2015, extraídos do Integrador de Registros Hospitalares de Câncer. Variáveis contextuais foram coletadas no Atlas do Desenvolvimento Humano, no Cadastro Nacional de Estabelecimentos de Saúde e no Sistema de Informações Ambulatoriais. Usou-se o modelo de regressão de Poisson multinível com intercepto aleatório. A prevalência de diagnóstico em estádio avançado foi de 48,4%, apresentando associação com idades mais avançadas (RP 1,06; IC 1,01-1,10), raça/cor da pele preta, parda e indígena (RP 1,04; IC 1,01-1,07), menores níveis de escolaridade (RP 1,28; IC 1,16-1,40), ausência de parceiro conjugal (RP 1,10; IC 1,07-1,13), encaminhamento do tipo público ao serviço de saúde (RP 1,07; IC 1,03-1,11) e menor taxa de realização de exame citopatológico (RP 1,08; IC 1,01-1,14). Os resultados reforçam a necessidade de melhorias no programa nacional de prevenção do câncer do colo do útero em áreas com baixa cobertura da citologia oncótica.
Abstract The scope of this study is to analyze the prevalence of advanced stage diagnosis of cervical cancer and its association with individual and contextual socioeconomic and healthcare service indicators in Brazil. A cross-sectional study was conducted using cervical cancer cases in women aged 18 to 99 years, from 2006 to 2015, extracted from the Hospital Cancer Registry (HCR) Integrator. Contextual variables were collected from the Atlas of Human Development in Brazil; the National Registry of Health Institutions (NRHI); and the Outpatient Information System. Multilevel Poisson Regression with random intercept was used. The prevalence of advanced stage diagnosis was 48.4%, revealing an association with older age groups (PR 1.06; CI 1.01-1.10), black, brown, and indigenous race/skin color (PR 1.04; CI 1.01-1.07), lower levels of schooling (PR 1.28; CI 1.16-1.40), no marital partner (PR 1.10; CI 1.07-1.13), public referral to the health service (PR 1.07; CI 1.03-1.11), and lower rates of cytological examination (PR 1.08; CI 1.01-1.14). The results reinforce the need for improvements in the national cervical cancer prevention program in areas with low coverage of oncotic cytology.
RESUMEN
Resumo O objetivo deste artigo é mapear a produção científica global sobre representações sociais ou culturais e câncer de mama no campo da saúde coletiva e discutir como esse fenômeno se apresenta na literatura. Foi realizada uma revisão de escopo, tendo como norte a seguinte pergunta: "Como representações culturais ou sociais no contexto do câncer de mama são descritas na produção científica global no âmbito da saúde coletiva?". As buscas foram realizadas em cinco fontes de literatura científica, sendo incluídos 45 estudos. O tratamento analítico seguiu a técnica de análise de conteúdo na modalidade temática. O acervo analisado pode ser tematizado nas seguintes categorias: (1) Comprometimento na imagem corporal e nas interações; (2) Espiritualidade; (3) Perda do controle da vida; (4) Seguir com a vida e (5) Associação a questões étnico-raciais. Apesar dos avanços da biomedicina, observa-se que nas representações do câncer de mama ainda permanecem metáforas associadas ao câncer no século passado. Conclui-se que, dentre outros aspectos, a atenção a mulheres com câncer de mama não pode ser pautada apenas pelas abordagens biomédica e epidemiológica, uma vez que essa doença é atravessada por saberes que competem com essas abordagens.
Abstract This article aims to map the global scientific production on social or cultural representations and breast cancer in Public Health and discuss how it is presented in the literature. We conducted a scoping review guided by the question: "How are cultural or social representations in the context of breast cancer described in the global scientific Public Health production?". We searched for works in five scientific literature sources and included 45 studies. The analytical process followed the content analysis technique in the thematic modality. The analyzed collection can be thematized into the following categories: (1) Compromised body image and interactions, (2) Spirituality, (3) Loss of control over life, (4) Going on with life, and (5) Association with ethnic-racial issues. Despite advances in biomedicine, we observed that representations of breast cancer still have metaphors associated with cancer in the last century. We conclude that, among other aspects, care for women with breast cancer cannot be guided only by biomedical and epidemiological approaches since this disease is traversed by knowledge that competes with these approaches.
RESUMEN
Abstract This article aims to analyze the clarity and engagement measures of publications on oral cancer in the Instagram profiles of official health agencies in Brazil. An infodemiological study was conducted with 81 profiles. Data collected concerned content classification, account and media, manner of addressing the topic, number of posts, likes, comments, views and hashtags. The clarity of the educational publications was assessed with the Brazilian version of the Clear Communication Index (BR-CDC-CCI). Data analysis involved Spearman's correlation and the Mann-Whitney test (α = 5%). A total of 775 publications on oral cancer were found. The average BR-CDC-CCI score was 69.8 (SD = 15.5). The clarity of the information was adequate in 9.5% of the educational publications. Positive correlations were found between the number of likes and engagement (comments [r = 0.49], views [r = 0.96]), number of hashtags (r = 0.13) and year of publication (r = 0.21). Publications from the Health Ministry had a significantly higher BR-CDC-CCI score compared to the other profiles. Publications on oral cancer were correlated with engagement, year of publication and number of hashtags. Public agencies increased publications to reach the population, but the clarity of the content was low.

A clareza das publicações educativas foi avaliada pela versão brasileira do Clear Communication Index (BR-CDC-CCI). A análise dos dados envolveu a correlação de Spearman e o teste de Mann-Whitney (α = 5%). Foram encontradas 775 publicações sobre câncer bucal. O escore médio do BR-CDC-CCI foi 69,8 (DP = 15,5). A clareza das informações foi adequada em 9,5% das publicações educativas. Correlações positivas foram encontradas entre o número de curtidas e engajamento (comentários [r = 0,49], visualizações [r = 0,96]), número de hashtags (r = 0,13) e ano de publicação (r = 0,21). Publicações do Ministério da Saúde apresentaram escore do BR-CDC-CCI significativamente maior do que os demais perfis (p = 0,01). As publicações sobre câncer bucal foram correlacionadas com engajamento, ano de publicação e número de hashtags. Os órgãos públicos aumentaram as publicações para atingir a população, mas a clareza do conteúdo foi baixa.
RESUMEN
Determinar el nivel de conocimiento sobre cáncer oral (CO) que presentaron los estudiantes de pregrado de estomatología. Estudio observacional transversal aplicado a una muestra poblacional de 184 estudiantes (24±3,09 años y 72,8 % mujeres) de una universidad privada de Lima del sexto a décimo ciclo que estuvieron matriculados en un curso de clínica (14,1 % de clínica V). Un cuestionario virtual y presencial con 24 preguntas sobre CO fue aplicado. El instrumento fue validado por juicio de expertos, tuvo un índice de validez de 0,96 (V de Aiken) y una confiabilidad (KR-20) DE 0,856 y ≥0,837 por ítem. La frecuencia de respuestas correctas del total de preguntas fue de 56,6 % siendo similar por sexo y curso de clínica, pero mayor en los >30 años (60 %). Las preguntas mejor contestadas fueron el tipo más frecuente (epidemiología), el factor relacionado (diagnóstico) y factores pronósticos (prevención). Las dimensiones mejor contestadas fueron en tratamientos y complicaciones (72,2 %) y diagnóstico (70,3 %) sobre CO. El nivel de conocimiento sobre CO fue regular (78,8 %). Ni las dimensiones, niveles o puntajes se asociaron a edad, sexo o clínica (P>0,05). Los estudiantes presentaron un nivel de conocimiento regular sobre cáncer oral, indistintamente del sexo, edad o la clínica que cursan.
The objective of this study was to determine the level of knowledge about oral cancer (OC) presented by undergraduate stomatology students. A cross-sectional observational study applied to a population sample of 184 students (24±3.09 years and 72.8 % women) from a private university in Lima from the sixth to tenth cycle who were enrolled in a clinical course (14.1 % of clinic V). A virtual and in-person questionnaire with 24 questions about OC was applied. The instrument was validated by expert judgment, it had a validity index of 0.96 (Aiken's V) and reliability (KR-20) of 0.856 and ≥0.837 per item. The frequency of correct answers to the total number of questions was 56.6 %, being similar by sex and clinical course, but higher in those >30 years of age (60 %). The best-answered questions were the most frequent type (epidemiology), the related factor (diagnosis), and the prognostic factors (prevention). The dimensions best answered were in treatments and complications (72.2 %) and diagnosis (70.3 %) of CO. The level of knowledge about OC was regular (78.8 %). Neither dimensions, levels, nor scores were associated with age, sex, or clinical features (P>0.05). The students presented a regular level of knowledge about oral cancer, regardless of sex, age or the clinical course they studied.

Resumen Introducción : El endofenotipo de cáncer de mama triple negativo (TNBC) es uno de los menos frecuentes y sin diana terapéutica, por tanto, se plantea estudiar la correlación del punto de control inmunológico PD-L1 con el establecimiento de microambiente tumoral evaluado por la infiltración linfocitaria intratumoral estromal (TILs) y su importancia en la práctica clínica. Métodos : Se realizó un estudio retrospectivo de casos y controles, con 31 casos de carcinoma infiltrante de la mama triple negativo y 57 controles no pareados de endofenotipo Luminal A, Luminal B y HER-2 atendidos en un año. Se evaluaron las variables: tipo y grado his tológico, expresión PD-L1 con el clon 22C3, TILs, invasión linfovascular, tamaño tumoral, compromiso de ganglios linfáticos y metástasis. El análisis estadístico se ejecutó con la prueba de chi cuadrado y prueba de coeficiente de correlación de Spearman. Resultados : Se encontró una correlación negativa estadísticamente significativa entre TILs y PD-L1 (rho - 0.106, p 0.025), indicando que a mayor expresión de PD-L1, es menor la infiltración linfocitaria intratumo ral. En los grupos de TILs B (10-40% TILs) y C (40-90% TILs) donde se presenta marcado infiltrado inflamatorio intratumoral se evidenció mayor número de pacientes negativos para PD-L1 (CPS <10) con 16 y 10 casos res pectivamente. Para los casos TNBC se logró identificar un coeficiente de asociación negativa (rho -0.378) y con significancia estadística (p 0.01). Discusión : Se estableció la asociación de TNBC, TILs y expresión de PDL1, lo cual es importante para la instau ración de terapias diana y el desarrollo de la medicina de precisión.
Abstract Introduction : Triple negative breast cancer endophe notype (TNBC) is one of the least frequent and without therapeutic target; therefore we propose to study the correlation of PD-L1 immune checkpoint with the es tablishment of tumor microenvironment assessed by intratumoral stromal lymphocyte infiltration (TILS) and its importance in clinical practice. Methods : A retrospective case-control study was performed, with 31 cases of triple-negative infiltrat ing breast carcinoma and 57 unmatched controls of Luminal A, Luminal B and HER-2 endophenotype seen in one year. The following variables were evaluated: histologic type and grade, PD-L1 expression with clone 22C3, TILS, lymphovascular invasion, tumor size, lymph node involvement and metastasis. Statistical analysis was performed with the chi-square test and Spearman correlation coefficient test. Results : a statistically significant negative correlation was found between TILS and PD-L1 (rho - 0.106, p 0.025), indicating that the higher the expression of PD-L1, the lower the intratumoral lymphocytic infiltration. In the TILS B (10-40% TILS) and C (40-90% TILS) groups where there was a marked intratumoral inflammatory infiltrate, a greater number of patients were negative for PD-L1 (CPS <10) with 16 and 10 cases, respectively. For TNBC cases a negative association coefficient was identified (rho -0.378) with statistical significance (p 0.01). Discussion : The association between TNBC, TILS and PDL1 expression was established, which is important for the establishment of target therapies and the develop ment of precision medicine.
RESUMEN
Resumen Introducción : El cáncer colorrectal (CCR) es un pro blema de salud a nivel global. En el sector público de Bahía Blanca, el tamizaje de CCR es oportunista, por solicitud de sangre oculta en materia fecal (SOMF). El objetivo de este trabajo es describir el acceso al tamiza je de CCR de la población con cobertura pública exclu siva que reside en el área programática 2 de la ciudad entre 2019 y 2021, y relevar las barreras y facilitadores que lo determinan. Métodos : Se estimó la tasa de uso anual y acumula da de SOMF. Las barreras y facilitadores se relevaron a través de 41 entrevistas individuales semi-estructuradas al personal de salud del área programática, el Hospital Municipal, Secretaría de Salud y usuarios/no usuarios del sistema. Resultados : La tasa acumulada de uso de SOMF en el período fue 4.8%. Entre las barreras al tamizaje per cibidas se destacan: la dificultad en el acceso a estudios de mayor complejidad para pacientes con SOMF+, el desconocimiento y falta de percepción del CCR como un problema de salud por parte de la población y la baja adherencia de los profesionales a los lineamientos. La territorialidad y el vínculo de los centros de salud con la población, y la predisposición de usuarios y profesio nales a incorporar el tamizaje surgen como facilitadores del mismo. Conclusiones : El relevamiento de las barreras orien tará el diseño de estrategias adaptadas al contexto que permitan en el futuro reforzar el tamizaje.
Abstract Introduction : Colorectal cancer (CRC) is a global health problem. In the public sector of Bahía Blanca, CRC screening is opportunistic, through the request of fecal occult blood test (FOBT). The objective of this study is to describe access to CRC screening for the population with exclusive public coverage residing in the program matic area 2 of the city between 2019 and 2021, and to identify the barriers and facilitators that determine it. Methods : The annual and cumulative usage rate was estimated based on the number of patients who requested FOBT. The barriers and facilitators were studied through 41 semi-structured individual inter views to healthcare staff from the area, the Municipal Hospital, Health Secretariat and users/non-users of the system. Results : The cumulative usage rate of FOBT during the period was less than 5%. Among the perceived bar riers to screening, we found: the difficulties in accessing more complex studies for patients with positive FOBT, the lack of population awareness and perception of CRC as a health problem, the low adherence of professionals to guidelines. The territoriality and link of health centers with the population, as well as the willingness of users and professionals to incorporate screening, emerge as facilitators. Conclusion : The identification of barriers and facilita tors will allow the design of context-adapted strategies that will strengthen screening in the future.
RESUMEN
Resumen Introducción : En Argentina la cobertura al tamizaje de cáncer colorrectal (CCR) es muy baja. El objetivo de esta revisión fue relevar y sintetizar la evidencia sobre la efectividad de estrategias dirigidas a incrementar la adherencia al tamizaje de CCR del personal de salud y población con riesgo promedio. Métodos : Revisión de revisiones sistemáticas (RS) que evaluaron la efectividad de dichas estrategias. Bús queda en bases de datos electrónicas, meta-buscadores, biblioteca Cochrane y búsqueda manual. Aplicación de criterios de elegibilidad e inclusión; con evaluación de la calidad de las RS a través del AMSTAR-II y la certeza de la evidencia por el método GRADE. Síntesis temática sobre la base de la taxonomía de estrategias propuesta por Dougherty (dirigidas al paciente/comunidad; a pro fesionales; otro tipo de estrategias). Resultados : Se identificaron 635 estudios; 36 fueron elegibles y 11 se descartaron por no contar con cali dad suficiente, incluyéndose 10 RS. Se identificó una multiplicidad de estrategias de efectividad variada, la mayoría dirigida a la población. Entre estas, destacan la educación, el auto-test con recolección en lugares específicos y recordatorios. En el caso de profesionales, solo educación y recordatorios mostraron ser efectivas. La combinación de estrategias mostró tener mayor efec tividad que las estrategias aisladas. Conclusiones : Es mayor la evidencia sobre estrategias dirigidas a la población que a profesionales. Las estrate gias combinadas demostraron tener mayor efectividad, lo que destaca la necesidad de explorar, en cada con texto, las barreras en la población y en los profesionales para priorizar y combinar aquellas que demostraron ser efectivas y tendrían mayor impacto.
Abstract Introduction : Coverage for colorectal cancer screening in Argentina is very low. The objective of this review is to assess and synthesize the evidence on the effectiveness of strategies aimed at increasing adherence to colorectal cancer screening among healthcare personnel and the general population at average risk. Methods : A review of systematic reviews (SRs) that evaluated the effectiveness of these strategies was con ducted. Searches were performed in electronic data bases, meta-search engines, the Cochrane Library, and through manual searching. Eligibility and inclusion criteria were applied, with assessment of the quality of the SRs using AMSTAR II and the certainty of evidence using the GRADE approach. Thematic synthesis was con ducted based on the taxonomy of strategies proposed by Dougherty (patient/community-targeted, professional-targeted, and other types of strategies). Results : A total of 635 studies were identified, with 36 deemed eligible and 11 excluded due to insufficient quality, resulting in the inclusion of 10 SRs. A multi plicity of strategies with varying effectiveness were identified, with the majority targeting the population. Among these, education, self-testing with specimen collection at specific locations, and reminders stood out. For professionals, only education and reminders showed effectiveness. Combined strategies demonstrated greater effectiveness than isolated strategies. Conclusions : There is more evidence on strategies targeting the population than professionals. Combined strategies showed greater effectiveness, highlighting the need to explore barriers in both the population and professionals in each specific context in order to priori tize and combine those that have proven effective and would have a greater impact.
RESUMEN
Fundamento: como promedio se han generan tres millones de casos de cáncer de piel a nivel global en los últimos años. Esta situación ocurre entre otras razones por la constante exposición a la radiación solar y la no aplicación de fotoprotección. Objetivo: determinar la experiencia parental en fotoprotección durante la infancia. Método: se realizó un estudio etnográfico en la Unidad Educativa de la Parroquia San Juan del Cantón Riobamba, Provincia Chimborazo, durante el período de estudio de octubre 2022 a octubre 2023. Se realizaron 14 entrevistas a cuidadores de preescolares, los que fueron escogidos a través del muestreo no probabilístico. Se dispuso de dos técnicas de recolección de la información: el autorreportaje y la entrevista semiestructurada. Resultados: se describieron cada una de las categorías que emergieron en el estudio según el nivel de frecuencia: fotounidad, fotoexperiencia-conocimiento y fotosanidad. Se construyó un mapa representacional en el cual se determinó que la familia en sí representa la fotounidad, mediante la participación de todos sus miembros en la protección de los efectos nocivos del sol. La sombrilla que cubre a la familia refleja la fotoexperiencia-conocimiento adquiridos por los cuidadores, que actúan como protección al daño solar mediante medidas preventivas y de cuidado. El sol y sus rayos solares simbolizan la fotosanidad, que corresponde a la exposición a rayos solares y sus efectos nocivos para la salud. Conclusiones: la implementación de medidas de fotoprotección desde edades tempranas resulta de vital importancia para la prevención del cáncer de piel, por lo que es necesario brindarles a los padres información adecuada sobre los riesgos solares y las medidas preventivas.
Foundation: on average, three million cases of skin cancer have been generated globally in recent years. This situation occurs among other reasons due to constant exposure to solar radiation and non-application of photoprotection. Objective: determine parental experience in photoprotection during childhood. Method: an ethnographic study was carried out in the Educational Unit of the San Juan Parish of the Cantón Riobamba, Chimborazo Province, during the study period from October 2022 to October 2023. 14 interviews were carried out with preschool caregivers, who were chosen through of non-probabilistic sampling. Two information collection techniques were available: self-report and semi-structured interview. Results: each of the categories that emerged in the study were described according to the level of frequency: photounity, photoexperience-knowledge and photosanity. A representational map was constructed in which it was determined that the family itself represents photounity, through the participation of all its members in protecting themselves from the harmful effects of the sun. The umbrella that covers the family reflects the photo-experience-knowledge acquired by the caregivers, which act as protection from sun damage through preventive and care measures. The sun and its solar rays symbolize photosanity, which corresponds to exposure to sunlight and its harmful effects on health. Conclusions: the implementation of photoprotection measures from an early age is of vital importance for the prevention of skin cancer, so it is necessary to provide parents with adequate information about sun risks and preventive measure.
RESUMEN
RESUMEN Antecedentes: la duodenopancreatectomía cefálica (DPC) con resección vascular venosa está indicada para el tratamiento del adenocarcinoma ductal y de tumores neuroendocrinos de páncreas, tanto por laparoscopia como por laparotomía. Objetivo: describir los resultados de una serie de pacientes operados de DPC con resección vascular venosa y comparar la morbimortalidad entre los abordados por laparoscopia y por laparotomía. Material y métodos: se realizó un estudio observacional, comparativo, retrospectivo de pacientes con DPC con resección vascular entre enero de 2022 y agosto de 2023. El abordaje laparoscópico fue determinado en menores de 80 años, invasión venosa tumoral igual a 180° o menor en la tomografía, buen performance status, y no haber realizado tratamiento neoadyuvante. Resultados: fueron realizadas 23 DPC con resección vascular venosa: 11 por laparoscopia y 12 por laparotomía. Las 11 realizadas por laparoscopia fueron resecciones laterales, y, en los 12 abordados por laparotomía, se realizó resección total de vena porta en 5 y en el resto, resección lateral. El tiempo de "clampeo" (pinzamiento) portal y la necesidad de transfusiones fue similar en ambos grupos. El estudio patológico reveló R0 en el 78,2% de los pacientes e invasión venosa en el 40.9%. La morbilidad con laparoscopia y con laparotomía consistió, respectivamente, en: fístula pancreática en 7 (4 y 3), vaciamiento gástrico retardado en 4 (1 y 4), fístula biliar en uno (1 y 0), neumonía en dos (1 y 1) e infección de herida en uno (0 y 1). La mortalidad fue de 8,6% por el fallecimiento de dos pacientes, uno en cada grupo. Conclusión: de acuerdo con los criterios empleados, la morbimortalidad de la DPC con resección vascular fue similar por laparoscopia y por laparotomía.
ABSTRACT Background: Cephalic pancreaticoduodenectomy (CPD) with venous resection is indicated for the treatment of ductal adenocarcinoma and neuroendocrine tumors of the pancreas, either through laparoscopy or laparotomy. Objective: The aim of this study was to describe the results of a series of patients undergoing CPD with venous vascular resection and compare morbidity and mortality between the laparoscopic approach and open surgery. Material and methods: We conducted a retrospective, comparative and observational study of patients who underwent CPD with venous vascular resection between January 2022 and July 2023. Criteria for laparoscopic surgery were age < 80 years, interface between tumor and vein of 180° of the circumference of the vessel wall or less on computed tomography, good performance status, and no previous neoadjuvant treatment. Results: A total of 23 CPD procedures with venous vascular resection were performed: 11 by laparoscopy and 12 by laparotomy. The 11 laparoscopic procedures were lateral resections, and in the 12 patients approached by laparotomy, 5 were total portal vein resections and 7 were lateral resections. Portal vein clamping time and need for transfusion was similar in both groups. The pathological examination reported R0 resections in 78.2% and venous invasion in 40.9%. The complications associated with laparoscopy and laparotomy were pancreatic fistula in 4 and 3 patients, respectively, delayed gastric emptying in 1 and 4 patients, respectively, biliary fistula in 1 and 0 patients, respectively, aspiration pneumonia i 1 and 1 patients, respectively and surgical site infection in 0 and 1 patients, respectively. Mortality was 8.6% (n =2), one in each group. Conclusion: According to the criteria used, the morbidity and mortality of CPD with vascular resection were similar for laparoscopy and laparotomy.
RESUMEN
Objetivo: Describir morbimortalidad asociada al uso de prótesis colorrectales (PC) e identificar factores asociados a sus complicaciones durante los años 2007 a 2022 en Clínica INDISA. Material y Método: Estudio transversal retrospectivo basado en registro clínico. Resultados: Se instalaron 49 PC con un 100% de éxito de desobstrucción. El 87,8% en colon izquierdo. La etiología principal fue la patología maligna 91,8% y el 85,7% de ellos fueron primarios colorrectales. Se instalaron 34 como tratamiento paliativo (TP), 12 como puente a cirugía electiva (PCE) y 3 por patología benigna. La tasa de complicaciones fue de 26,5% (7 estenosis, 4 perforaciones y 2 migraciones). La mortalidad asociada fue de 4,1% (2 pacientes). El grupo de complicados fue más joven, con etapas oncológicas más avanzadas y con estenosis en rectosigmoides(p < 0,005). Los menores de 50 años tuvieron 5 veces más riesgo de alguna complicación (OR = 5,0;IC95%:1,09-23,0; p = 0,039). Discusión: El uso de PC tiene baja morbimortalidad. Su uso principal es como TP o PCE en obstrucción colorrectal maligna, con alta tasa de desobstrucción. Está asociado con menor morbilidad que la cirugía de urgencia, menor tasa de ostomía y mayor cosecha ganglionar. La instalación como puente se asocia además a mayor tasa de anastomosis primaria. Nuestra serie mostró mayor tasa de complicación en aquellos con tumores avanzados y más jóvenes. Conclusión: El uso de PC es seguro y con baja morbimortalidad. La principal indicación es en neoplasia colorrectal obstructiva como TP. Tienen mayor riesgo de complicación los pacientes jóvenes y los tumores colorrectales avanzados con ganglios peri tumorales.
Objective: To describe morbidity and mortality associated with colorectal prostheses (CP) and identify factors associated with their complications during the 2007 to 2022 at INDISA Clinic. Material and Method: Retrospective cross-sectional study based on clinical registry. Results: 49 CPs were installed with 100% clearing success. 87.8% in left colon. The main etiology was malignant 91.8% and 85.7% were primary colorectal. 34 were installed with palliative intention, 12 as a bridge to elective surgery (BTS) and 3 for benign pathology. There were 13 (26.5%) patients with adverse effects (7 strictures, 4 perforations and 2 migrations). Associated mortality was 4.1% (2 patients). The complicated group was younger, with more advanced oncological stages and rectosigmoid stenosis (p < 0.005). Those under 50 years of age had 5 times higher risk of some complication (OR = 5.0; 95% CI: 1.09-23.0; p = 0.039). Discussion: The use of CPs has low short-term morbidity and mortality. Its main use is as palliative treatment or BTS in malignant colorectal obstruction. It's a high clearance rate. It is associated with less morbidity than emergency surgery, a lower ostomy rate, and a higher lymph node harvest. Installation as a bridge is also associated with a higher rate of primary anastomosis. Our group showed a higher complication rate in those with advanced and younger tumors. Conclusion: The use of CPs is safe, with low morbidity and mortality. The main indication is in obstructive colorectal neoplasia as palliative treatment. Young patients and advanced colorectal tumors with peritumoral nodes have a higher risk of complications.
RESUMEN
En la actualidad, más de la mitad de las pacientes con cáncer de mama receptor hormonal positivo recibe algún esquema de quimioterapia adyuvante. Sin embargo, sólo algunas de ellas obtendrían un beneficio real en términos de sobrevida. Las plataformas genómicas permiten un mejor entendimiento de la heterogeneidad tumoral entre carcinomas con receptores hormonales positivos, Her2 negativos, habiendo sido validadas como herramientas para identificar aquellas. pacientes que obtendrían un beneficio claro con el tratamiento quimioterápico. El objetivo de nuestro estudio es describir el uso de la plataforma genómica Oncotype Dx® y evaluar su impacto sobre la indicación del tratamiento adyuvante, evaluado principalmente a través del cambio de conducta en relación con la indicación final del tratamiento adyuvante. Material y método: Estudio multicéntrico observacional de cohorte llevado a cabo en distintas Unidades de Mastología de la República Argentina que utilizaran el Oncotype Dx* para esclarecer la indicación del tratamiento adyuvante en pacientes luminales Her2neu negativas en estadio inicial. Se registraron las decisiones relacionadas con el tratamiento antes y luego de realizar la prueba genómica. El objetivo secundario consistió en describir los eventos en aquellas pacientes en quiénes se solicitó dicho estudio. Resultados: Entre enero de 2013 y diciembre de 2018, 211 pacientes con carcinomas luminales A o B, Her2neu negativas realizaron el Oncotype Dx* y fueron incluidas en el estudio. Según nuestros registros, 40% de las pacientes experimentó un cambio en la indicación del tratamiento adyuvante luego de realizada la plataforma genómica. De aquellas pacientes que tenían indicación inicial de hormonoterapia según parámetros tradicionales clínico-patológicos, 24% recibió adicionalmente quimioterapia. En relación con las pacientes que tenían indicación inicial de quimio y hormonoterapia, 49% experimentó un cambio en la indicación de su adyuvancia pudiendo realizar únicamente hormonoterapia. En relación a los eventos descriptos en las pacientes participantes del trabajo, se registraron 4 muertes específicas por la enfermedad, una muerte por otra causa, 2 recaídas a distancia y un cáncer de mama contralateral. Conclusiones: En nuestra población de estudio el uso del Score de Recurrencia (RS) resultó clínicamente significativo en relación al cambio de conducta en la toma de decisión para adyuvancia. En consecuencia, para este grupo de investigadores, ha demostrado ser una herramienta de significativa importancia en la decisión del tratamiento adyuvante de pacientes con cáncer de mama temprano, luminal, Her2neu negativo(AU)
Objetive: Currently, over half of all patients diagnosed with hormone-receptor positive early stage breast cancer will receive some type of adjuvant chemotherapy (CHT), but only a few of them will actually benefit in terms of survival. Genomic platforms allow a better understanding of the heterogeneity among the different types of hormone receptor positive, her2 negative breast cancer, and have proven their validity as tools for identifying those patients who will obtain a clear benefit from CHT. The aim of our study was to analyze the use of the genomic platform Oncotype Dx® in our population and describe its impact on the decision of adjuvant treatment assessed through change in treatment decision. Material and method: this was a real world collaborative observational study, which was performed across several Breast Units in Argentina. Patients who underwent Oncotype Dx® testing to determine adjuvant treatment were included. Decisions regarding treatment were settled before and after the oncotype was performed by the tumor boards of each Breast Unit. Results: From January 2013 to December 2018, 211 patients with luminal A or B, her 2 negative breast cancer who underwent Oncotype Dx" testing were included. We found that treatment decisions were modified after Oncotype DX in approximately 40% of patients. In 24% percent of cases, chemotherapy was added to the initial treatment plan although endocrine therapy alone had initially been considered (potential subtreatment); and on the other hand, 49% of all patients were able to receive endocrine therapy only when, due to traditional prognostic factors, they would have received chemotherapy (potential overtreatment). Conclusions: In our population, we found that the use of the Recurrence Score was associated with a significant change in treatment recommendation We therefore consider it to be a very important tool and a decisive factor for the selection of adjuvant treatment in patients with hormone receptor positive, her2neu negative early breast cancer(AU)
RESUMEN
Introducción: Las mujeres con predisposición genética-familiar presentan un riesgo más elevado de desarrollar cáncer de mama. La vigilancia es una de las estrategias más efectivas para ofrecer a este subgrupo de mujeres, sin embargo la adherencia a la misma puede ser dificultosa. Objetivo: Analizar la adherencia de las pacientes con Alto Riesgo Heredo-Familiar (ARHF) al programa específico de "Seguimiento de pacientes de Alto Riesgo" del Hospital Universitario Austral. Material y método: Se revisaron de forma retrospectiva datos de 104 mujeres sanas con ARHF que ingresaron al programa de vigilancia: "Seguimiento de pacientes de Alto Riesgo" del Hospital Universitario Austral en el período comprendido entre junio de 2016 a febrero de 2022. Resultados: La adherencia al programa fue total en 38 pacientes (36,54%) y parcial en 42 (40,38%). Se observó falta de adherencia en 24 pacientes (23,07%). La causa más prevalente fue la incomodidad al realizar la resonancia (54,16%). Analizando la adherencia según el año de ingreso al programa se observa una caída significativa a partir del 3er año de seguimiento y solo 48,98% completaron la sexta ronda. Conclusiones: La falta de adherencia observada fue significativa. Los datos demostrados apuntan a una necesidad de continuar desarrollando estrategias que faciliten el seguimiento(AU)
Introduction: Women with a genetic-familial predisposition have a higher risk of developing breast cancer. Surveillance is one of the most effective strategies to offer this subgroup of women, however adherence to it can be difficult. Objetive: To analize the adherence of patients with High Risk of Familial-Hereditary (HRFH) breast cancer to a specific program: "Follow-up in High Risk patients" of the Austral University Hospital. Material and method: Data from 104 women with HRFH who were admitted to the surveillance program: "Follow-up in High Risk patients" of the Austral University Hospital in the period from june 2016 to february 2022 were retrospectively reviewed. Results: Adherence to the program was complete in 38 patients (36,54%) and partial in 42 (40,38%). 24 (23,07%) patients had lack of adherence. The most prevalent cause was discomfort when performing the resonance (54,16%). When we analyze adherence according to the year of admission to the program, a significant drop is observed from de 3rd year of follow-up and only 48,98% completed round six. Conclusions: The observed lack of adherence was significant. The demonstrated data points to a need to continue developing strategies that facilitate monitoring(AU)

Introducción: La conservación mamaria ha evolucionado y cada vez se utilizan más técnicas oncoplásticas para obtener mejores resultados cosméticos. Además, esta técnica permite escisiones más amplias que previenen deformidades mamarias mediante la reconstrucción de grandes defectos de resección. Objetivo: Reportar con un caso clínico: estrategia quirúrgica de una paciente con cáncer de mama multicéntrico y cirugía conservadora oncoplástica de la mama. Caso clínico: Paciente de 72 años con mamas grandes ptosis Grado III con diagnóstico de carcinoma mamario derecho multicéntrico Estadio IA mT1cNO luminal A anatómico - pronóstico. Deseos de la paciente de conservar la mama. Se decide mastoplastía terapéutica + Ganglio centinela (GC) + mastopexia y reducción contralateral. Anatomía patológica: mama derecha: carcinoma ductal infiltrante multicéntrico GC 0/3. Mama izquierda: 1 foco de 2 mm carcinoma lobulillar infiltrante de tipo clásico score II de nottingham. margen libre. Inmunohistoquimica: RE 95%, RP 95%, Her2 neu negativo score 0 y ki67 2%. Se discute caso en unidad de mastología, se decide: Radioterapia 3D bilateral y hormonoterapia con anastrazole. Discusión: La Mastoplastia terapéutica es considerada una opción de tratamiento estándar para pacientes seleccionados garantizando la conservación mamaria con seguridad oncológica aceptable, adecuados resultados estéticos y similar supervivencia. Permite la escisión tumoral con márgenes de resección más amplios y resultados oncológicos y estéticos aceptables. Creemos que es esencial brindar información precisa para ayudar a la paciente en la toma de decisiones sobre las consecuencias específicas de cualquier técnica oncoplástica. Conclusiones: La oncoplastia extrema debe ser utilizada solamente para casos seleccionados. Deberá ser evaluado por un equipo multidisicplinario, idealmente en el contexto de una unidad de mastología integrada por: cirujanos mastólogos, radioterapeutas, imagenólogos, oncólogos, anatomopatólogos y psicooncólogos. La técnica quirúrgica debe ser realizada preferentemente por cirujanos de mama con formación oncoplástica y reconstructiva de la mama(AU)
Introduction: Breast conservation has evolved and more oncoplastic techniques are used to obtain better cosmetic results. In addition, this technique allows wider excisions that prevents breast deformities by reconstructing large resection defects. Objetivo: Report with a clinical case: surgical strategy of multicentric breast cancer and oncoplastic breast-conservative surgery. Clinical case: A 72-year-old patient with large breasts with Grade III ptosis diagnosed with multicentric right mammary carcinoma Stage IA mT1cNO luminal A anatomical - prognosis. The patient's wishes to preserve the breast. Therapeutic mastoplasty + sentinel node (SLN) + mastopexy and contralateral reduction was decided. Pathology: right breast: multicentric infiltrating ductal carcinoma GC 0/3. Left breast: 1 focus of 2-mm infiltrating lobular carcinoma of the classic Nottingham score II type. free margin. Inmunohystochemistry: RE 95%, RP 95%, Her2 neu negative score 0 and ki67 2%. The case is discussed in the mastology unit, and we decided: Bilateral 3D radiotherapy and hormone therapy with anastrozole. Discussion: Therapeutic mastoplasty is considered a standard treatment option for selected patients, guaranteeing breast conservation with acceptable oncological safety, adequate aesthetic results and similar survival. It allows tumor excision with wider resection margins and acceptable oncological and cosmetic results. We believe that it is to provide accurate information to help the patient in making essential decisions about the specific consequences of any oncoplastic technique. Conclusions: Extreme oncoplasty should only be used for selected cases. It must be evaluated by a multidisciplinary team, ideally in the context of a mastology unit made up of: breast surgeons, radiotherapists, imaging specialists, oncologists, pathologists and psycho-oncologists. The surgical technique should preferably be performed by breast surgeons with oncoplastic and reconstructive training of the breast(AU)
