Abstract Objective To calculate and analyze the mortality rates from breast cancer in women under 50 years of age in Colombia and to compare them with those of other countries in the region. Methods Based on data from the registry of deaths in 2018 and the results of the National Population and Housing Census of Colombia for the same year, specific mortality rates in women with breast cancer, specific mortality according to age group, standardized by age, proportional mortality, potential years of life lost, and years of life expectancy lost in women under 50 years of age who died from breast cancer were calculated. The mortality rate of regional countries was consulted on the Global Cancer Observatory webpage. Results In the group from 20 to 49 years, the specific mortality rate was higher in the age range from 45 to 49 years, with a rate of 23.42 × 100,000, a value that was above the specific mortality rate due to breast cancer in women in Colombia, 15.17 × 100.000. In the age range of 45 to 49 years, the potential years of life lost were 42.16. Of the 0.275 years of life expectancy lost by the population due to this neoplasia, women under 50 years of age represented 0.091 (33%). Colombia is the fifth in the rank of mortality in Latin American countries in this age group. Conclusion Breast cancer in patients from 30 to 59 years is the number one cause for the decrease in life expectancy of women in Colombia. Women under 50 years of age represent one third of this decrease. This neoplasm is also the leading cause of mortality in women younger than 50 years in South America.

Introducción: El cáncer de mama es una causa de muerte evitable en las mujeres de hasta 74 años de edad. Sin embargo, es el cáncer más frecuente y la primera causa de muerte por tumores en esa población. Objetivo: Analizar las tendencias de la mortalidad por cáncer de mama en las mujeres de Argentina entre 2005 y 2020, considerando el grupo de edad y la región geográfica. Método: Estudio cuantitativo y descriptivo con perspectiva sociodemográfica. Se calcularon tasas específicas de mortalidad a partir de datos oficiales y se aplicaron modelos de regresión joinpoint para evaluar su tendencia temporal. Resultados: La tasa de mortalidad ajustada por cáncer de mama disminuyó significativamente (PPCA: −1,5%; IC95%: −1,3% a −0,7%); sin embargo, aumentó en las mujeres de 25 a 34 años (PPCA: 2,3%; IC95%: 1,4% a 3,2%). El descenso registrado se trasladó mayormente a las regiones Centro, Cuyo y Noroeste, mientras que las tasas de mortalidad de las regiones Noreste y Patagónica no variaron significativamente. Conclusiones: No obstante los progresos documentados, se evidencian desafíos para reducir la mortalidad por cáncer de mama en las poblaciones más jóvenes. Asimismo, persisten las desigualdades regionales, lo que destaca la importancia de adaptar las acciones a las necesidades del territorio.

Background: Breast cancer is a preventable cause of death among women up to 74 years of age. However, it is the most common cause of cancer death among this population. Objective: To analyze female breast cancer mortality trends in Argentina between 2005 and 2020, taking into account age groups and geographical regions. Method: Quantitative and descriptive study carried out from a socio-demographic perspective. Specific mortality rates were calculated based on official data, and joinpoint regression models were applied to evaluate time trends in mortality. Results: The adjusted mortality rate attributed to breast cancer decreased significantly (AAPC: −1,5%; CI95%: −1,3% to −0,7%); however, it increased among women aged 25-34 (AAPC: 2,3%; CI95%: 1,4% to 3,2%). Besides, the decreasing of mortality took place mainly in Central, Cuyo and Northwest regions meanwhile the mortality rates from Northeast and Patagonia regions didnt vary significantly. Conclusions: Although progress has been made, there are still some challenges regarding the reduction of breast cancer mortality in young women. In addition, regional disparities remain, highlighting the importance to adapt actions to territorial needs.

Introduction: The relationship between the tumor inflammatory infiltrate, also known as tumor-infiltrating lymphocytes (TILs), and invasive breast carcinomas has been extensively studied in recent years to verify its association with prognosis and response to treatment. The goal of this study was to associate the presence of TILs with patient's survival time. Methods: We studied prognostic clinicopathological characteristics already established in the literature and their impact on overall five-year survival time of patients with invasive breast cancer treated at Hospital Santa Casa in Belo Horizonte, Minas Gerais, Brazil, in 2011 (n=290). This was an observational and retrospective study. Results: The presence of TILs was associated with tumors of no special type (p=0.018) and with younger age of the patients (p=0.042). Smaller tumor size (HR: 19.24; 95%CI 4.30­86.15; p<0.001), absence of metastasis to the axillary lymph nodes (HR: 2.80; 95%CI 1.02­7.70; p=0.002), positivity for progesterone receptor (HR: 0.39; 95%CI 0.17­0.87; p=0.022), and presence of TILs (HR: 0.23; 95%CI 0.08­0.65; p=0.005) were associated with longer survival times. Conclusions: This study suggests that the presence of TILs, along with other clinicopathological characteristics, is a prognostic factor in breast cancer

Introduction: Breast cancer is the most common female cancer and the leading cause of cancer death in women around the world. It has repercussions not only on human health, but also on health services due to the high incidence resulting in a large number of consultations and treatments. The disease is responsible for a large demand for hospitalizations throughout Brazil, where an increase in mortality rates is observed and Santa Catarina does not differ from the national scenario. The study aimed to analyze the temporal trend of the breast cancer mortality rate in the state of Santa Catarina from 1996 to 2019 Methods: This is an ecological epidemiological study of time series of breast cancer mortality in the population residing in the state according to age groups and health macro-regions. Data were obtained from the Mortality Information System and the Brazilian Institute of Geography and Statistics. Simple linear regression of standardized mortality rates according to the world standard population was performed. p<0.05 was considered significant. Results: Data showed 9,637 deaths in the period. There was a significant upward trend in mortality in the state (from 6.50 to 7.92/100,000 women). An upward trend was observed in the age groups of 30­39 years, 60­69 years, and over 80 years. All seven health macro-regions showed an upward trend in mortality. Conclusion:The overall mortality rate from breast cancer in Santa Catarina showed a significant upward trend. A significant increase was also observed in the age groups of 30­39 years, 60­69 years, and 80 years old or older and in all health macro-regions. Problems in public health infrastructure, lack of control of risk factors and deficiency in mammographic screening are revealed. The elaboration and strengthening of public policies to control the disease are fundamental.

Objetivo: Avaliar o acesso e a adesão da população feminina, atendida pelo Sistema Único de Saúde (SUS), à Diretriz Brasileira de Detecção Precoce do Câncer de Mama, em duas cidades de médio porte de uma região metropolitana do estado de São Paulo, Brasil. Métodos: Estudo transversal. Os dados foram coletados no Sistema de Informação do Câncer (Siscan) e nas Secretarias Municipais de Saúde no período de 01/01 a 31/12 de 2017. Resultados: Em Santa Bárbara d'Oeste, foram realizadas 3.106 mamografias: 2.931 (94,4%) BI-RADS® 1-2; 21 (0,7%) BI-RADS® 3; 12 (0,4%) BI-RADS® 4-5; 142 (4,5%) BI-RADS® 0. A maioria dos exames (1.855 ­ 59,7%) foi realizada em mulheres de 50 a 69 anos. A cobertura mamográfica na população de risco foi de 11,2%. O envelhecimento foi relacionado ao BI-RADS® 4-5 (p = 0,005). A idade jovem esteve relacionada ao maior número de BI-RADS® 0 (p = 0,03). Em Vinhedo, foram realizadas 1.996 mamografias: 1.835 (91,9%) BI-RADS® 1-2; 9 (0,45%) BI-RADS® 3; 7 (0,35%) BI-RADS® 4-5; 145 (7,3%) BI-RADS® 0. A maioria dos exames (975 ­ 48,8%) foi realizada em mulheres de 50-69 anos. A população coberta pela mamografia foi de 17%. Reunindo ambas as análises populacionais, evidenciou-se que o envelhecimento esteve relacionado ao maior número de casos suspeitos (p = 0,007). Conclusão: A maioria das mamografias foi realizada em mulheres de 50-69 anos. A cobertura mamográfica ficou aquém da encontrada no Brasil e recomendada pela Organização Mundial da Saúde.

Objective: To evaluate the access and adherence of the female population, assisted by Health Unic System (SUS), to Brazilian Breast Cancer Early Detection Guideline in two medium-sized cities of a metropolitan region in the State of São Paulo, Brazil. Methods: Cross-sectional study. Data were collected from the Cancer Information System (Siscan) and from the Municipal Health Secretariats between 01/01 to 12/31, 2017. Results: In Santa Bárbara d'Oeste 3,106 mammograms were performed: 2,931 (94.4%) BI-RADS® 1-2; 21 (0.7%) BI-RADS® 3; 12 (0.4%) BI-RADS® 4-5; 142 (4.5%) BI-RADS® 0. Most of the exams (1,855 ­ 59.7%) among women aged 50-69 years. The mammographic coverage at risk population was 11.2%. Aging was related to BI-RADS® 4-5 (p = 0.005). The young age was related to the highest number of BI-RADS® 0 (p = 0.03). In Vinhedo 1,996 mammograms were performed: 1,835 (91.9%) BI-RADS® 1-2; 9 (0.45%) BI-RADS® 3; 7 (0.35%) BI-RADS® 4-5; 145 (7.3%) BI-RADS® 0. Most of the exams (975 ­ 48.8%) among women aged 50-69 years. The population covered by mammography was 17%. Gathering both population analysis, it was shown that aging was related to the highest number of suspected cases (p = 0.007). Conclusion: Most mammograms were performed between 50-69 years. Mammographic coverage fell short of that found in Brazil and recommended by the World Health Organization.

INTRODUÇÃO: O câncer de mama é a neoplasia mais incidente entre mulheres, representando 24,5% entre todos os tipos de câncer nesta população. Além disto, representa a maior causa de morte neste grupo, respondendo por 15,5% dos óbitos entres todos os tipos de cânceres femininos. A faixa etária a partir de 50 anos é mais acometida, sendo relativamente raro antes dos 35 anos. As estratégias de detecção precoce são a base da Política Nacional de Atenção ao Câncer de Mama através do rastreamento e o diagnóstico precoce. Entretanto, parte significativa das mulheres brasileiras recebem o diagnóstico em estágios mais avançados da doença, principalmente nas regiões menos desenvolvidas do país. OBJETIVO: Avaliar os resultados e o impacto do programa de rastreamento e diagnóstico de câncer de mama, na Região de Saúde Juazeiro, Bahia (RSJ/BA), no período de 1998 a 2017. MATERIAL E MÉTODOS: foi realizado um estudo retrospectivo de serie temporal, avaliando as taxas de mortalidade por câncer de mama antes e após a implantação do serviço de diagnóstico do câncer na cidade de Juazeiro-BA, referência em diagnóstico de câncer na MSJ/BA, composta por dez cidades. As informações foram coletadas do Sistema de Informação de Mortalidade e Instituto Brasileiro de Geografia e Estatística, estabelecidas tendências temporais através do softwere JoinPoint e verificadas correlações entre distância e o IDH dos municípios através do teste de correlação de Pearson. Foram descritas características e perfil tumoral de todas as mulheres diagnosticadas no período de 2014 a 2018 através do softwere stata 11. RESULTADOS: As taxas de mortalidade aumentaram após implantação do serviço de diagnóstico, com tendência de crescimento da mortalidade, porém, com maior intensidade após a implantação do serviço. Houve correlação negativa entre as taxas de mortalidade e a distância das cidades e positiva com o IDH dos municípios. A maioria dos casos diagnosticados no serviço de referência (27%) ocorreu em 2018, na faixa etária de 50 a 69 anos (58%), CONCLUSÕES: A tendência de aumento da taxa mortalidade na RSJ/BA coincide com a implantação do serviço de rastreamento e diagnóstico precoce na cidade de Juazeiro ­ BA. Em todas as cidades atendidas pelo serviço, houve aumento das taxas de mortalidade, onde o acesso ao exame de MMG foi facilitado pela implantação do atendimento da unidade móvel de rastreamento e diagnóstico, principalmente nos municípios mais distantes, localizadas a mais de 200 km do centro de diagnóstico. As mulheres residentes em locais mais distantes dos serviços têm mais dificuldades para acessar o diagnóstico precoce e apresentam tumores maiores ao diagnóstico. Aprofundar o conhecimento e a compreensão das condições do acesso ao diagnóstico e tratamento é importante para melhorar as chances de prevenção e sobrevida das mulheres sertanejas.

INTRODUCTION: Breast cancer is the most frequent neoplasm among women, representing 24.5% of all types of cancer in this population. In addition, it represents the major cause of death in this group, accounting for 15.5% of deaths among all types of female cancers. The age group from 50 years is more affected, being relatively rare before the age of 35 years. Early detection strategies are the basis of the National Breast Cancer Care Policy through screening and early diagnosis. However, a significant part of Brazilian women are diagnosed at more advanced stages of the disease, especially in less developed regions of the country. OBJECTIVE: To evaluate the results and impact of the breast cancer screening and diagnosis program in the Juazeiro Health Region, Bahia (RSJ/BA), from 1998 to 2017. MATERIAL AND METHODS: a retrospective serial study was carried out temporal, evaluating breast cancer mortality rates before and after the implementation of the cancer diagnosis service in the city of Juazeiro-BA, reference in cancer diagnosis in MSJ/BA, composed of ten cities. The information was collected from the Mortality Information System and the Brazilian Institute of Geography and Statistics, temporal trends were established using the JoinPoint software and correlations between distance and the HDI of the municipalities were verified using Pearson's correlation test. Characteristics and tumor profile of all women diagnosed in the period from 2014 to 2018 were described using the software stata 11. RESULTS: Mortality rates increased after the implementation of the diagnostic service, with a tendency for mortality to increase, but with greater intensity after the implementation of the service. There was a negative correlation between mortality rates and distance from cities and a positive correlation with the HDI of municipalities. Most cases diagnosed in the referral service (27%) occurred in 2018, in the age group from 50 to 69 years (58%). CONCLUSIONS: The trend towards an increase in the mortality rate in RSJ/BA coincides with the implementation of a screening and early diagnosis service in the city of Juazeiro - BA. In all cities served by the service, there was an increase in mortality rates, where access to the MMG test was facilitated by the implementation of the mobile tracking and diagnosis unit, especially in the most distant municipalities, located more than 200 km from the center. of diagnosis. Women residing in locations further away from services have more difficulties in accessing early diagnosis and present larger tumors at diagnosis. Deepening the knowledge and understanding of the conditions of access to diagnosis and treatment is important to improve the chances of prevention and survival of sertaneja women.

Resumen Introducción: En 2017, el INEGI reportó 84 142 defunciones por tumores malignos en México y la Organización Mundial de la Salud indicó que la tasa de mortalidad por cáncer de mama en 2018 fue de 11.2 por 100 mil mujeres. Objetivo: Mostrar la tendencia de la mortalidad por cáncer de mama en mujeres según municipio y región sanitaria de Jalisco en el periodo 2010-2017. Método: Estudio analítico en el que se estimaron tasas estandarizadas de mortalidad y riesgos relativos por municipio de residencia de 3873 mujeres. Se utilizó estadística espacial de dispersión y tendencia central. Resultados: La tasa de mortalidad aumentó de 10.7 a 13.0 por 100 mil mujeres en el periodo 2010-2017. Los valores más altos se encontraron en los municipios de Chapala (21.2) y Guadalajara (19.5), la tasa de mortalidad aumentó en cuatro de cada 10 municipios y el riesgo relativo fue hasta 50 veces mayor en algunos del occidente y centro de Jalisco. Conclusiones: Se observó un incremento de 1.0 % anual, aunque territorialmente diferenciado. Los resultados representan una oportunidad para mejorar los procesos de detección y diagnóstico oportunos, así como para garantizar la cobertura de los servicios.

Abstract Introduction: In 2017, INEGI reported 84,142 deaths from malignant tumors in Mexico, while the World Health Organization indicated that the breast cancer mortality rate in 2018 was 11.2 per 100,000 women. Objective: To show the trend of breast cancer mortality in women by municipality and health region of Jalisco in the 2010-2017 period. Method: Analytical study in which standardized mortality rates and relative risks of 3873 women were estimated by municipality of residence. Dispersion and central tendency spatial statistics were used. Results: The mortality rate increased from 10.7 to 13.0 per 100,000 women in the 2010-2017 period. The highest values were found in the municipalities of Chapala (21.2) and Guadalajara (19.5); the mortality rate increased in four out of every 10 municipalities, and relative risk was up to 50-fold higher in some of the western and central Jalisco municipalities. Conclusions: An annual increase of 1.0 % was observed, although it was territorially differentiated. The results represent an opportunity to improve timely detection and diagnostic processes, as well as to guarantee the coverage of services.

ABSTRACT Background: About 80% of breast cancer (BC) cases express estrogen receptor (ER), which has been correlated with good prognosis and response to estrogen deprivation Aim: To characterize ER positive advanced BC (ABC) patients treated at our institution assessing the impact of clinical pre-sentation (stage IV, de novo disease at diagnosis versus systemic recurrence) and BC subtype on survival rates. Material and Methods: We evaluated 211 ER+ advanced BC (ABC) patients, treated between 1997 and 2017. Results: The median overall survival (OS) was 37 months. Median OS for the period 1997/2006 and 2007/2017 were 33 and 42 months, respectively (p = 0.47). Luminal A, ABC stage IV disease at diagnosis displayed better OS rates than Luminal B stage IV tumors (100 and 32 months respectively, p < 0.01). Conclusions: Clinical presentation (stage IV vs. systemic recurrence) and tumor subtype are key determinants of OS in ABC.

Antecedentes: Casi el 80% de los casos de cáncer de mama (CM) son positivos para receptores de estrógenos (RE+). Éstos se caracterizan por una mejor sobrevida y respuesta a terapia endocrina. Objetivo: Caracterizar a pacientes con CM avanzado (CMA), RE+, y determinar sobrevida según presentación clínica y subtipos. Material y Métodos: Analizamos en nuestra base de datos los antecedentes de 211 pacientes con CMA RE+, tratados en nuestra institución en el período 1997-2017. Se evaluó el impacto de la presentación clínica (estadio IV al diagnóstico, enfermedad de novo, versus recurrencia sistémica) y subtipo de CM, en los niveles de sobrevida. Resultados: La mediana de sobrevida global (SG) fue de 37 meses. La mediana de SG para el período 1997/2006 y 2007/2017 fue de 33 y 42 meses; respectivamente (p = 0,47). Pacientes con CMA, estadio IV, Luminal A al momento del diagnóstico mostraron mejores tasas de SG frente al estadio IV del Luminal B (100 y 32 meses respectivamente (p < 0,01). Conclusiones: La presentación clínica (estadio IV, de novo, versus recurrencia sistémica) y subtipo son determinantes clave de la SG en CMA.

En la actualidad, los análisis de distribución espacial mediante el uso de técnicas de clusters para enfermedades crónicas como el cáncer de mama, son relevantes para la identificación de patrones espaciales de la mortalidad por cáncer según áreas geográficas. Identificar clústeres espaciales de la mortalidad por cáncer de mama en mujeres a nivel de las provincias del Ecuador, entre 2004 al 2018. Estudio observacional, de tipo descriptivo, ecológico multigrupal que compara a nivel espacio ­ temporal las tasas de mortalidad por cáncer de mama en mujeres según las provincias del Ecuador, utilizando el índice de Móran para el análisis de autocorrelación y el algoritmo de k-medias para el análisis de agrupamiento en períodos quinquenales mediante el programa informático ArcGIS versión 10.5. Resultados. En el Ecuador, el 86,5% de las muertes por cáncer de mama en mujeres se registraron en el área urbana, dichas muertes tienen un patrón no aleatorio según el índice de Morán, distinto al área rural que tiene un patrón aleatorio; se identificó diferencia en el agrupamiento de la mortalidad por cáncer de mama en las provincias urbanas y rurales, donde se obtuvo para el área urbana, clústeres con altas, media-altas, media-baja y bajas tasas de mortalidad, mientras que en lo rural se obtuvieron solo clústeres con altas, medias y bajas tasas de mortalidad. La distribución espacial y el análisis de agrupamiento identificó clústeres de la mortalidad por cáncer de mama en el Ecuador, evidenciando entre lo urbano y rural diferencias en los clústeres obtenidos, siendo esta información de utilidad para la implementación de estrategias de control del cáncer en el país.

Currently spatial distribution analyzes through the use of cluster techniques for chronic diseases such as breast cancer are revealing for the identification of spatial patterns of cancer mortality according to geographic areas. Objective. Identify spatial clusters of breast cancer mortality in women at the level of the provinces of Ecuador, between 2004 to 2018. We used an observational, descriptive, ecological multigroup study that compares at a Spatio-temporal level the rates of breast cancer mortality in women according to the provinces of Ecuador, using the Moran index for the autocorrelation analysis and the k-, means algorithm for cluster analysis in five-year periods using the ArcGIS version 10.5 software. Results. In Ecuador, 86.5% of breast cancer deaths in women were recorded in the urban area, these deaths have a non-random pattern according to the Morán Index different from the rural area that has a random pattern; difference was identified in the grouping of breast cancer mortality in urban and rural provinces, where it was obtained for urban areas, clusters with high, medium. high, medium-low and low mortality rates. While in rural areas only clusters with high, medium and low mortality rates were obtained. Conclusions. The spatial distribution and cluster analysis identified clusters of breast cancer mortality in Ecuador; evidencing between urban and rural differences in the clusters obtained, this information is useful for the development of cancer control strategies in the country.

ABSTRACT OBJECTIVE To verify the spatial pattern of mortality from breast and cervical cancer in areas of primary health care, considering socioeconomic conditions. METHODS This is an ecological study, from January 2000 to December 2016. The study area is the municipality of São Paulo, Brazil, and its 456 coverage areas of primary health units. Information on deaths of women aged 20 years or over were geocoded according to residence address. We calculated mortality rates, standardized by age, and smoothed by the local empirical Bayesian method, and grouped into three or two years to reduce the random fluctuation of the data. In addition, bivariate global and local Moran indexes were calculated to verify the existence of spatial agglomeration of standardized mortality rates with a domain of socioeconomic condition, elaborated based on the Índice Paulista de Vulnerabilidade Social (IPVS - São Paulo Index of Social Vulnerability). RESULTS The success rate of geocoding was 98.9%. Mortality from breast cancer, without stratification by time, showed a pattern with higher rates located in central regions with better socioeconomic conditions. It showed a decrease at the end of the period and a change in spatial pattern, with increased mortality in peripheral regions. On the other hand, mortality from cervical cancer remained with the highest rates in peripheral regions with worse socioeconomic conditions, despite being reduced over time. CONCLUSION The spatial pattern of mortality from the studied cancers, over time, suggests association with the best socioeconomic conditions of the municipality, either as protection (cervical) or risk (breast). This knowledge may direct resources to prevent and promote health in the territories.

RESUMO OBJETIVOS Verificar o padrão espacial da mortalidade pelos cânceres de mama e do colo do útero, em áreas da atenção primária à saúde, levando em consideração as condições socioeconômicas. MÉTODOS O estudo é ecológico, de janeiro de 2000 a dezembro de 2016. A área de estudo é o município de São Paulo, Brasil, e suas 456 áreas de abrangência das unidades básicas de saúde. As informações sobre óbitos de mulheres com 20 anos ou mais de idade foram geocodificadas segundo endereço de residência. Foram calculadas as taxas de mortalidade, padronizadas por idade, e suavizadas pelo método bayesiano empírico local, além de agrupadas em três ou dois anos para reduzir a flutuação aleatória dos dados. Além disso, foram calculados os índices de Moran global e local bivariados, para verificar a existência de aglomeração espacial das taxas de mortalidade padronizadas com um domínio de condição socioeconômica, elaborado a partir do Índice Paulista de Vulnerabilidade Social. RESULTADOS A taxa de sucesso da geocodificação foi de 98,9%. A mortalidade por câncer de mama, sem estratificação por tempo, apresentou um padrão com maiores taxas localizadas nas regiões centrais e com melhores condições socioeconômicas. Apresentou queda ao final do período e mudança de padrão espacial, com aumento da mortalidade nas regiões periféricas. Já a mortalidade por câncer do colo do útero manteve-se com as maiores taxas nas regiões periféricas e com piores condições socioeconômicas, apesar de apresentar redução ao longo do tempo. CONCLUSÃO O padrão espacial da mortalidade pelos cânceres do estudo, ao longo do tempo, sugere associação com as melhores condições socioeconômicas do município, seja como proteção (colo) ou risco (mama). Esse conhecimento pode direcionar recursos para a prevenção e a promoção da saúde nos territórios.

INTRODUCCIÓN El cáncer de mama es la neoplasia maligna más común en las mujeres en todo el mundo y en Chile, siendo la primera causa de muerte oncológica femenina. Se ha reportado amplia variación en la mortalidad, con focos geográficos de mayor riesgo. OBJETIVO Analizar espacialmente la mortalidad por cáncer de mama en mujeres de la Región Metropolitana en 2015. MÉTODOS Estudio ecológico. Se utilizaron los datos de los registros de defunciones del año 2015 (C50 según CIE10), y las proyecciones poblacionales del Instituto Nacional de Estadísticas. Se calcularon tasas de mortalidad por cáncer de mama brutas y razones de mortalidad estandarizadas. Se realizó un análisis epidemiológico espacial estimando el índice I de Moran Global y Local para evaluar autocorrelación espacial. Los resultados se presentan en mapas (cartografía precenso 2016). RESULTADOS Se registraron 622 defunciones por cáncer de mama en la Región Metropolitana en 2015. La edad promedio de las mujeres fallecidas fue de 66 años (desviación estándar: 15,5). El 92,4% de las muertes se registró en zonas centrales o urbanas. Sin embargo, las mayores tasas de mortalidad se observaron en comunas periféricas. No se observó autocorrelación espacial global en la región (I de Moran de 0,007; p = 0,134). A nivel local, cuatro comunas se diferencian de forma significativa de sus vecinas. CONCLUSIONES El riesgo de morir por cáncer de mama en la Región Metropolitana de Chile se concentra en comunas periféricas. Cuatro comunas de la región presentan riesgos diferentes de sus comunas vecinas, por lo que es necesario explorar factores que explican la desigual distribución de las muertes.

INTRODUCTION Breast cancer is the most common malignancy in women worldwide and Chile, being the leading cause of female cancer death. A wide variation in mortality has been reported, with geographic clusters of higher risk. OBJECTIVE To spatially analyze mortality from breast cancer in women in the Metropolitan Region in 2015. METHODS Ecological study of location. We used death records in 2015 (C50 according to ICD10) and population projections of the Statistics Institute to estimate mortality rates. We calculated crude breast cancer mortality rates and standardized mortality ratios and performed a spatial epidemiological analysis of breast cancer mortality in women, estimating the global and local Moran I index to assess spatial autocorrelation. We present the results in maps according to the 2016 pre-census cartography. RESULTS There were 622 deaths from breast cancer in the Metropolitan Region in 2015. The mean age was 66 years (SD: 15.5). 92.4% of deaths were registered in urban or central areas. However, the highest mortality rates were observed in peripherical districts. No global spatial autocorrelation was observed in the region (Moran's I 0.007 p = 0.134). However, at the local level, four districts differ significantly from their neighbors. CONCLUSIONS The risk of dying from breast cancer in the Metropolitan Region of Chile is concentrated in women from peripherical communes. Four districts in the region present different risks from their neighboring districts. It is necessary to investigate local realities to prevent deaths from this pathology.

Al igual en otras partes del mundo, en Argentina la mortalidad específica por cáncer mamario disminuyó de forma sostenida entre 1996 y 2017. Es probable que en la actualidad la mamografía sea la herramienta más importante para detectar precozmente, evaluar y llevar un seguimiento de las personas con esta patología. Sin embargo existe mucha controversia acerca de los beneficios del tamizaje poblacional y de la realización de diagnósticos precoces de cáncer de mama. El propósito de esta revisión narrativa es brindar una mirada contraintuitiva, cuestionadora de los beneficios de esta práctica,ponderando también sus riesgos, escasamente visibilizados por las estrategias comunicacionales concordantes con el modelo deprevenir es mejor que curar y la lucha contra la historia natural del cáncer. (AU)

As in other parts of the world, in Argentina, breast cancer specific mortality declined steadily between 1996 and 2017. Mammography is currently the most important tool for early detection, evaluation and follow-up of people suffering fromthis disease. However, there is a controversy about the benefits of population screening and early diagnosis of breastcancer. The aim of this narrative review is to provide a counterintuitive, questioning view of the benefits of this practice, also weighing its risks, poorly visible through communication strategies consistent with the model of prevention is betterthan cureand the fight against the natural history of cancer.

Resumo A relevância do câncer de mama para as mulheres tem impulsionado pesquisas sobre a mortalidade desta doença. Todavia, estes estudos estão sujeitos aos problemas gerados pelos óbitos oriundos de causas mal definidas (CMD). A fim de evidenciar as possíveis distorções causadas pelas CMD em estudos que avaliam a mortalidade, foram calculadas taxas de mortalidade, padronizadas por faixa etária, com e sem correção para CMD, para os anos de 1990, 2000 e 2010. Feito isso, foram estimados modelos de regressão com dados em painel, que permitiram identificar que a correção para CMD: a taxa de mortalidade por câncer de mama dos municípios brasileiros elevou-se em cerca de 9% no período considerado; as taxas de mortalidade das regiões Sul, Sudeste, Nordeste e Norte se aproximaram; foi reduzida a tendência de crescimento da mortalidade em quase 60%, principalmente nas regiões Sudeste e Sul; aumentou, de forma mais acentuada, a mortalidade das cidades com menos de 5 mil habitantes; diminuiu a significância de grande parte dos fatores associados ao câncer de mama; revelou que o efeito da longevidade e dos gastos públicos em saúde estariam superestimados. Tais resultados ressaltam a importância da correção para CMD na geração de indicadores fidedignos de mortalidade.

Abstract The relevance of breast cancer for women has driven research about mortality of this disease. However, these studies are affected by problems generated by deaths due to ill-defined causes (IDC). To highlight distortions caused by IDC in studies that evaluate mortality, we calculated the age-standardized mortality rates of breast cancer, with and without adjustment for IDC for the years 1990, 2000, and 2010. Then, panel data regression models were estimated and enabled us to identify that the adjustment for IDC: has elevated breast cancer mortality rate of Brazilian municipalities by 9% in the period considered; has drawn mortality rates of the South, Southeast, Northeast and North regions closer; has reduced the increasing trend of mortality by almost 60%, mainly in the Southeast and South regions; has increased, more sharply, the mortality in cities with less than 5 thousand inhabitants; has curbed the significance of most factors associated with breast cancer; has revealed that the effect of longevity and the public health expenditure may be overestimated. These results highlight the importance of adjustment for IDC in producing reliable mortality indicators.

ABSTRACT Background: Breast cancer (BC) is the most common malignancy in women. Aim: To assess the impact of HER2 status on axillary lymph node (ALN) involvement in patients with invasive ductal carcinoma of no special type (IDC-NST) both at diagnosis and during the 4-year postoperative period. Patients and Methods: We retrospectively included 375 women with an early clinical stage of non-luminal IDC-NST who between 2007 and 2013 underwent breast surgery at a clinical hospital. They were divided into phenotype-based groups: HR+HER2-, HR+HER2+, HR-HER2+ and HR-HER2-. Only patients with sentinel lymph node (SLN) macrometastases underwent ALN dissection. If > 3 ALNs were positive, radiotherapy was delivered. All patients were treated with chemotherapy, HER2+ BC patients received trastuzumab, and hormone receptor (HR)-positive BC patients received hormonal therapy. Results: Larger tumor size, higher grade, HR+, HER2+ status, and lymphovascular invasion (LVI) were predictive for ALN metastases at diagnosis. The poorest overall, disease-free, and distant recurrence-free survival (OS, DFS, DRFS) were found in the HR-HER2- group, while the poorest locoregional recurrence-free survival (LRFS) was observed in HR-HER2+ and HR-HER2- groups. HER2 status was not predictor of survival. Conclusions: HER2+ status was predictive for ALN involvement at diagnosis but had no effect on 4-year LRFS in these patients.

Antecedentes: El cáncer de mama es el tumor maligno más común en mujeres. Objetivo: Conocer el impacto del estado HER2 sobre el compromiso ganglionar axilar al momento del diagnóstico y durante los primeros cuatro años después de la cirugía en mujeres con carcinoma ductal invasivo de tipo no especial (IDC-NST). Pacientes y Métodos: Incluimos retrospectivamente a 375 mujeres en etapas clínicas iniciales de IDC-NST que fueron operadas en un hospital clínico. Ellas se dividieron en grupos de acuerdo al fenotipo: HR+HER2-, HR+HER2+, HR-HER2+y HR-HER2-. La disección de ganglios axilares se efectuó solo en las pacientes con macrometástasis en el ganglio centinela. Si había más de tres ganglios comprometidos, se efectuó radioterapia. Todas las pacientes se trataron con quimioterapia. Las pacientes HER2+ recibieron trastuzumab y las pacientes HR+ recibieron hormonoterapia. Resultados: Tumores más grandes, de mayor grado de malignidad, HR+, HER2+ y la invasión linfovascular fueron predictivos de la presencia de metástasis axilares al momento del diagnóstico. La sobrevida más baja se observó en pacientes HR-HER2+. La sobrevida libre de recurrencia locorregional más baja, se observó en pacientes HR-HER2+ y HR-HER2-. HER2 no fue predictor de sobrevida. Conclusiones: En estas mujeres, HER2+fue predictor de la presencia de compromiso ganglionar axilar al momento del diagnóstico pero no de la sobrevida a cuatro años.

RESUMEN Introducción: en el último trienio la mortalidad por cáncer mamario en el sexo femenino en Cuba disminuyó ligeramente sus tasas, sin embargo no se han realizado estudios de supervivencia por esta enfermedad en la provincia Matanzas. Objetivo: evaluar el comportamiento del tiempo de supervivencia global a los 5 años en esta serie y valorar la sobrevida en función de variables seleccionadas. Materiales y métodos: se realizó un estudio observacional descriptivo, longitudinal y retrospectivo, en el que participaron 288 mujeres diagnosticadas con cáncer de mama en la consulta de mastología del Hospital "José Ramón López Tabranes" de la provincia Matanzas, desde el 1 de Enero del 2010 hasta el 31 de Diciembre del 2015. Se utilizó el método de Kaplan Meier para determinar el tiempo de supervivencia global a los 5 años y en función de variables seleccionadas. La comparación de las diferentes curvas para las variables de exposición se realizó con la prueba de Rangos Logarítmicos (Log Rank). Se consideró estadísticamente significativo el valor del estadígrafo mayor de 1 y p < 0.05. Resultados: la supervivencia global a los 5 años fue de un 66 %. Se registran supervivencias muy por debajo de los estándares internacionales para las pacientes en estadios III (37 %) y IV (0). La supervivencia global disminuye de manera significativa en la medida en que se incrementan el número de ganglios afectados y el tamaño del tumor al momento del diagnóstico. Conclusiones: la supervivencia global a los 5 años resultó inferior a la registrada en la mayoría de los estudios internacionales consultados. Se muestra una disminución marcada de la sobrevida en pacientes con estadios clínicos avanzados de la enfermedad: (III y IV).

ABSTRACT Introduction: in the last three years, mortality rates due to breast cancer in the female sex in Cuba slightly decreased, but studies of this disease survival have not been carried out in the province of Matanzas. Objective: to evaluate the behavior of the global survival time of this series at the 5th year and to assess survival according to chosen variables. Material and method: a retrospective, longitudinal, observational descriptive study was carried out; 288 women diagnosed with breast cancer took part on it; they were diagnosed in the mastology consultation of the hospital "Jose Ramon Lopez Tabrane", province of Matanzas during the period January 1st 2010- December 31st 2015. The Kaplan-Meier method was used to determine the global survival time at the 5th year according to chosen variables. The comparison of the different curves for the exposition variables was made using the Log Rank test. The test value higher than 1 and p < 0.05 was considered statistically significant. Results: global survival at the 5th year was 66 %. There are survival rates well below the international standards for the stage III (37 %) and stage IV (0) patients. Global survival significantly decreases insofar as the number of affected ganglia and the size of the tumor at the moment of the diagnosis increase. Conclusions: global survival at the 5th year was lower than the one recorded in most of the consulted international studies. There is a remarkable decrease of survival in patients with disease advanced clinical stages: III and IV.
