ABSTRACT

Introducción: El cáncer de mama es considerado como un serio problema de salud pública por la alta prevalencia tanto en países desarrollados como en desarrollo. Son escasos los estudios clínico-epidemiológicos actualizados en el área de salud del Policlínico 28 de septiembre relacionados con dicha entidad clínica. Objetivo: Caracterizar desde el punto de vista clínico y epidemiológico a pacientes con cáncer de mama del área de salud perteneciente al Policlínico 28 de septiembre. Métodos: Estudio descriptivo en una serie de 35 mujeres mayores de 30 años con diagnóstico confirmado de cáncer de mama. Las variables estudiadas comprendieron edad, antecedentes familiares de cáncer de mama, factores de riesgo generales y hormonales, signos y síntomas clínicos, resultados de estudio ecográfico y diagnóstico histopatológico. Se utilizó el porcentaje como medida de resumen. Resultados: El 42,8 por ciento de la muestra objeto de estudio estuvo comprendido en el grupo de edad de 40-49 años. El 65,7 por ciento del total de mujeres tenía antecedentes familiares de cáncer de mama. La menarquía precoz (54,2 por ciento) y la nuliparidad (48,5 por ciento) representaron los factores de riesgo de mayor incidencia. El 57,1 por ciento de las lesiones diagnosticadas correspondieron a carcinomas en estadío I y IIa. Conclusiones: El cáncer de mama constituye un serio problema de salud en mujeres mayores de 30 años pertenecientes al Policlínico 28 de septiembre del municipio Santiago de Cuba(AU)


Introduction: Breast cancer is considered a serious public health concern due to its high prevalence in both developed and developing countries. There are few updated clinical-epidemiological studies carried out in the health area of the Policlínico Docente 28 de Septiembre related to this clinical entity. Objective: To characterize, from the clinical and epidemiological point of view, the patients with breast cancer and from the health area belonging to the Policlínico Docente 28 de Septiembre. Methods: A descriptive study was carried out with a series of 35 women aged more than 30 years and with a confirmed diagnosis of breast cancer. The variables studied included age, family history of breast cancer, general and hormonal risk factors, clinical signs and symptoms, ultrasound findings and histopathological diagnosis. Percentage was used as summary measure. Results: 42.8 percent of the study sample was in the age group 40-49 years old. Of the total number of women, 65.7 percent had a family history of breast cancer. Early menarche (54.2 percent) and nulliparity (48.5 percent) represented the risk factors with the highest incidence. 57.1 percent of the diagnosed lesions corresponded to stage I and IIA carcinomas. Conclusions: Breast cancer is a serious health problem in women older than 30 years and belonging to the Policlínico Docente 28 de Septiembre, of Santiago de Cuba Municipality(AU)

ABSTRACT

Introducción: Los factores reproductivos se asocian con cáncer de mama. Actualmente se estudia el comportamiento según subtipos moleculares. Objetivo: Establecer la prevalencia de estos subtipos y su asociación con factores reproductivos en mujeres atendidas en centros del nororiente colombiano. Método: Estudio observacional de corte transversal, en mujeres con cáncer de mama subtipos luminales y HER2 durante 2012-2021. Se indagaron variables sociodemográficas, factores reproductivos y estadio tumoral. Resultados: En total, 347 pacientes cumplieron criterios de elegibilidad, correspondiendo a luminal A el 49,8% (intervalo de confianza del 95% [IC95%]: 44,5-55,1), a luminal B el 29,1% (IC95%: 24,3-33,9) y a HER2 el 15,5% (IC95%: 11,7-19,4). Las mujeres con tumores de mama luminal B tenían más riesgo de tener estadios localmente avanzados (odds ratio [OR]: 1,83; IC95%: 1,11-3,01; p = 0,02). Agrupando los subtipos luminales frente a HER2 se encontró que el 40,72% de las pacientes con subtipos luminales no habían lactado, frente al 69,71% con HER2 (diferencia estadísticamente significativa a favor de luminal A; OR: 1,91; IC95%: 1,02-3,53; p = 0,041). Conclusiones: La prevalencia de tumores luminales es del 84,5%. Existe asociación diferencial entre el antecedente de lactancia materna y la aparición de subtipos luminales, es decir, las mujeres que no lactaron se corresponden con mayor frecuencia con HER2. No se estableció asociación con otros factores estudiados.


Introduction: Stimulus-estrogenic factors are associated with breast cancer. Currently, the behavior according to molecular subtypes is being studied. Objective: To establish the prevalence of these subtypes and their association with reproductive factors in women attended in centers in northeastern Colombia. Method: Observational cross-sectional study in women with breast cancer subtypes luminal and HER2 during 2012 -2021. Sociodemographic variables, stimulus-estrogenic factors and tumor stage were investigated. Results: In total, 347 patients met eligibility criteria, corresponding to luminal A 49.8% (95% confidence interval [95%CI]: 44.5-55.1), luminal B 29.1% (95%CI: 24.3-33.9) and HER2 15.5% (95%CI: 11.7-19.4). Women with luminal B breast tumors were at higher risk of having locally advanced stages (odds ratio [OR]: 1.83; 95%CI: 1.11-3.01; p = 0.02). Grouping the luminal subtypes versus HER2 showed that 40.72% of patients with luminal subtypes had not lactated, compared to 69.71% HER2 (statistically significant difference in favor of luminal A; OR: 1.91; 95%CI: 1.02-3.53; p = 0.041). Conclusions: The prevalence of luminal tumors is 84.5%. There is a differential association between the history of breastfeeding and the appearance of luminal subtypes, i.e., women who did not breastfeed are more likely to have HER2. No association was established with other factors studied.

ABSTRACT

Introducción: El sarcoma primitivo de la mama es el tumor maligno no epitelial menos frecuente. Se trata de una entidad infrecuente que presenta una incidencia menor al 1 por ciento de las neoplasias malignas de la mama y menos del 5 por ciento de todos los sarcomas. Objetivo: Presentar una serie de casos con diagnóstico de sarcoma de la mama por la baja incidencia de esta enfermedad a nivel mundial, su agresividad y su curso precario. Presentación de caso: Se presentan siete pacientes con diagnóstico de sarcoma de la mama, de las cuales seis correspondieron al sexo femenino; la edad promedio fue de 52,8 años. Desde el punto de vista anatomopatológico el diagnóstico fue heterogéneo pues se encontraron: tumor phylodes maligno, fibrosarcomas, sarcoma epitelioide, sarcoma pleomórfico y sarcoma de células claras. Conclusiones: El sarcoma de la mama es una entidad rara y poco frecuente(AU)


Introduction: Primitive sarcoma of the breast is the least frequent nonepithelial malignant tumor. It is a rare entity whose incidence accounts for less than 1 percent of malignant neoplasms of the breast and less than 5 percent of all sarcomas. Objective: To present a series of cases diagnosed with sarcoma of the breast due to the low incidence of this disease worldwide, as well as its aggressiveness and precarious course. Case presentation: Seven patients with a diagnosis of sarcoma of the breast are presented, six of whom were female. Their average age was 52.8 years. From the anatomopathological point of view, the diagnosis was heterogeneous, since malignant phyllodes tumor, fibrosarcomas, epithelioid sarcoma, pleomorphic sarcoma and clear cell sarcoma were found. Conclusions: Sarcoma of the breast is a rare and infrequent entity(AU)

ABSTRACT

Introducción: El cáncer ha causado más muertes que todas las guerras y catástrofes conocidas. En particular, el cáncer de mama se ha convertido en una pandemia que amenaza con seguir propagándose. Objetivo: Describir las diferencias en cuanto a los resultados obtenidos de la cirugía conservadora y radical como tratamiento del cáncer de mama. Métodos: Se realizó un estudio analítico, observacional, descriptivo y retrospectivo en un universo de 177 pacientes con diagnóstico de cáncer de mama en el servicio de Cirugía General del Centro de Investigaciones Médico Quirúrgicas de La Habana, Cuba. Todas recibieron tratamiento quirúrgico en el período comprendido de enero de 2011 a diciembre de 2016. Resultados: De las pacientes estudiadas, el 92,09 por ciento no presentaron antecedentes de patología mamaria, mientras que el 36,72 por ciento tuvieron como antecedente patológico familiar cáncer de mama. Predominaron las pacientes mayores de 70 años en ambas técnicas quirúrgicas. En el grupo de 30-40 años solamente se practicaron técnicas conservadoras. Con respecto al estadiamiento, predominó la etapa II de la enfermedad. La sobrevida global a los 5 años fue superior al 90 por ciento, mientras que el intervalo libre de enfermedad se mantuvo en valores similares para ambas técnicas. Conclusiones: Se realizaron mayor número de cirugías conservadoras de mama en pacientes que se encontraban en etapas clínicas más tempranas de la enfermedad y la sobrevida global de los procedimientos conservadores fue ligeramente mayor(AU)


Introduction: Cancer has caused more deaths than all known wars and catastrophes. Particularly speaking, breast cancer has become a pandemic that threatens to continue to spread. Objective: To describe the differences based on the results obtained from conservative and radical surgery as a treatment for breast cancer. Methods: An analytical, observational, descriptive and retrospective study was carried out with a universe of 177 female patients diagnosed with breast cancer in the general surgery service of Centro de Investigaciones Médico Quirúrgicas, of La Habana, Cuba. All of them received surgical treatment in the period from January 2011 to December 2016. Results: 92.09 percent of the patients studied had no history of breast pathology, while 36.72 percent had breast cancer as a family pathological history. Patients over 70 years of age predominated in both surgical techniques. In the group of 30-40 years of age only conservative techniques were performed. With respect to staging, there was a predominance of the disease in stage II. Overall survival at 5 years was higher than 90 percent, while the disease-free interval remained at similar values for both techniques. Conclusions: A greater amount of breast-conserving surgeries were performed in patients at earlier clinical stages of the disease, while overall survival of conservative procedures was slightly higher(AU)

ABSTRACT

BACKGROUND: The success of breast cancer (BC) treatment depends largely on the clinical-histological characteristics of the patient. Immunohistochemical (IHC) Breast Cancer Subtypes are crucial for therapeutic purposes. AIM: To determine the relevance and prevalence of the histopathological parameters and molecular subtypes of BC among women attending public health services. MATERIAL AND METHODS: A retrospective cross-sectional study was carried out in 199 female patients with histopathological diagnosis of breast cancer, treated at a Guayaquil city hospital in Ecuador, from January 2014 to December 2017. RESULTS: Luminal A carcinoma was the most prevalent tumor in the studied women (54%). Thirty seven percent of patients did not have nodal involvement, 40% had one to three lymph nodes involved and 2% had 10 or more nodes involved. Most patients had a tumor size > 2 and ≤ 5 cm (72%) and moderately differentiated specifications (57%). CONCLUSIONS: The study allowed the characterization of breast cancer according to the prevalence of molecular subtypes and clinical and histological characteristics. These factors determine therapeutic behaviors that optimize the use of the limited resources of the Public Health System.

ABSTRACT

Objective: To analyze the trends of incidence and age change for global female breast cancer in different regions of the world according to the database from Cancer Incidence in Five Continents Time Trends (CI5plus) published by the International Association of Cancer Registries (IACR). Methods: The recorded annual female breast cancer (ICD-10: C50) incidence data and corresponding population at-risk data (1998-2012) were extracted from CI5plus published by IACR. The annual change percentage and average annual change percentage (AAPC) were calculated to examine the trends of incidence. The age-standardized mean age at diagnosis and proportion of incidence cases by age were calculated to analyze the relationship between incidence and age. Results: For crude incidence, except in Northern America, all other regions showed an upward trend, with Asia showing the most obvious upward trend (AAPC: 4.1%, 95% CI: 3.9%, 4.3%). For age-standardized incidence, in Asia, Latin America and Europe, the rising trends had slowed down, in Oceania and Africa, the trends began to be stable, and in Northern America, the trend showed a downward trend (APPC: -0.6%; 95% CI: -1.0%, -0.1%). The mean age at diagnosis were increased from 1998 to 2012 in Asia, Latin America, Oceania and Europe, with an annual increase of 0.12 years, 0.09 years, 0.04 years and 0.03 years, respectively. But after age-standardized, only Europe still kept increasing year by year, with an annual increase of 0.02 years, while Northern America showed a decreasing trend, with an annual decrease of about 0.03 years. Conclusions: From 1998 to 2012, the trends of incidence and age change for global female breast cancer vary in different regions of the world, and the global population aging is widespread, which affects the trend of the actual age change. Prevention and control strategies should be targeted at different age groups in different regions.

ABSTRACT

OBJECTIVE@#To develop and validate a three-year risk prediction model for new-onset cardiovascular diseases (CVD) among female patients with breast cancer.@*METHODS@#Based on the data from Inner Mongolia Regional Healthcare Information Platform, female breast cancer patients over 18 years old who had received anti-tumor treatments were included. The candidate predictors were selected by Lasso regression after being included according to the results of the multivariate Fine & Gray model. Cox proportional hazard model, Logistic regression model, Fine & Gray model, random forest model, and XGBoost model were trained on the training set, and the model performance was evaluated on the testing set. The discrimination was evaluated by the area under the curve (AUC) of the receiver operator characteristic curve (ROC), and the calibration was evaluated by the calibration curve.@*RESULTS@#A total of 19 325 breast cancer patients were identified, with an average age of (52.76±10.44) years. The median follow-up was 1.18 [interquartile range (IQR): 2.71] years. In the study, 7 856 patients (40.65%) developed CVD within 3 years after the diagnosis of breast cancer. The final selected variables included age at diagnosis of breast cancer, gross domestic product (GDP) of residence, tumor stage, history of hypertension, ischemic heart disease, and cerebrovascular disease, type of surgery, type of chemotherapy and radiotherapy. In terms of model discrimination, when not considering survival time, the AUC of the XGBoost model was significantly higher than that of the random forest model [0.660 (95%CI: 0.644-0.675) vs. 0.608 (95%CI: 0.591-0.624), P < 0.001] and Logistic regression model [0.609 (95%CI: 0.593-0.625), P < 0.001]. The Logistic regression model and the XGBoost model showed better calibration. When considering survival time, Cox proportional hazard model and Fine & Gray model showed no significant difference for AUC [0.600 (95%CI: 0.584-0.616) vs. 0.615 (95%CI: 0.599-0.631), P=0.188], but Fine & Gray model showed better calibration.@*CONCLUSION@#It is feasible to develop a risk prediction model for new-onset CVD of breast cancer based on regional medical data in China. When not considering survival time, the XGBoost model and the Logistic regression model both showed better performance; Fine & Gray model showed better performance in consideration of survival time.

ABSTRACT

Breast cancer is associated with high frequency and mortality in Brazilian women. There have been limited studies portraying the characteristics of breast cancer cases in the countryside of the state of Minas Gerais for a long period of time, a fact that will allow us to better understand the epidemiology of these tumors. This descriptive study aims to analyze the epidemiology and clinical features of patients with breast cancer treated at a public health service facility in Lavras, MG. Methods: This is a transversal study with 299 women diagnosed with breast cancer between 2002 and 2022, based on data collection from medical records and subsequent descriptive analysis. Results: There were a total of 317 cases, and 299 were eligible for the study. The mean age at diagnosis was 54.2 years, and 36.1% of the patients were under 50 years old at diagnosis. Positive family history was found in 17.0% of the patients. The diagnosis was made by clinical alteration detected on physical examination in 71.5% of cases, and lump was the most frequent type of lesion (89.0%). Invasive carcinoma was 93.1% of the cases, and the mean tumor size was 28.6 mm. The average time between first medical appointment and diagnosis was 63.2 days, and between diagnosis and beginning of treatment was 39.6 days. Conclusions: This study showed that a significant number of cases occurred in women outside the recommended age for screening in Brazil. Diagnosis was predominantly performed by clinical examination, with delays in obtaining the histological diagnosis, and the stage at diagnosis was high, and these facts were associated with the health system limitations (AU)

ABSTRACT

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.

ABSTRACT

Este estudo teve como objetivo analisar o perfil dos casos de câncer de mama no estado do Acre no período de 2015 a 2019. Trata-se de um estudo quantitativo com delineamento transversal. A amostra foi constituída por todos os casos de câncer de mama registrados no Acre e inseridos no Departamento de Informática do Sistema Único de Saúde (DATASUS) no período de 2015 a 2019. Foram identificados no período 293 casos da doença, com maior número de casos registrados no ano de 2019 (25,0%), sendo a maioria do sexo feminino (98,0%), na faixa etária de 40 a 49 anos (29,0%). O tempo decorrido desde o diagnóstico até o início do tratamento foi de mais de 60 dias (51,0%). A modalidade terapêutica mais utilizada foi a quimioterapia (55,0%). O local da realização do tratamento ocorreu capital do estado Rio Branco (80,0%). A maior parte dos acometidos, ainda encontra-se em tratamento (56,0%), no entanto (44,0%) evoluiu para óbito. O aumento da doença com o passar dos anos é notável no Acre. É importante destacar que ações voltadas para a prevenção e controle do câncer de mama continuam sendo fundamentais para auxiliar na diminuição do número de casos, como o rastreamento e diagnóstico precoce.


This study aimed to analyze the profile of breast cancer cases in the state of Acre in the period from 2015 to 2019. This is a quantitative study with a cross-sectional design. The sample consisted of all breast cancer cases registered in Acre and inserted in the Informatics Department of the Unified Health System (DATASUS) in the period from 2015 to 2019. In the period 293 cases of the disease were identified, with a greater number of cases registered in 2019 (25.0%), with the majority being female (98.0%), aged 40 to 49 years (29.0%). The time elapsed from diagnosis to the start of treatment was more than 60 days (51.0%). The most used therapeutic modality was chemotherapy (55.0%). The place where the treatment was performed took place in the state of Rio Branco (80.0%). Most of the people affected are still under treatment (56.0%), however (44.0%) died. The increase in the disease over the years is notable in Acre. It is important to highlight that actions aimed at the prevention and control of breast cancer continue to be fundamental to assist in reducing the number of cases, such as screening and early diagnosis.

ABSTRACT

BACKGROUND: Mammograms are one of the most effective preventive means for the early detection of breast cancer. OBJECTIVE: To describe the features of patients and results of mammograms performed at a public breast imaging service of the Santiago Metropolitan Area. MATERIAL AND METHODS: We reviewed the reports of mammograms performed on 174,017 women and 18 men, between 2008 and 2018 in an Imaging Center. The BI-RADS classification was used in the reports. RESULTS: Forty-six percent of mammograms (75,781) were reported as BI-RADS 2. The high proportion of BI-RADS 4 reports (674 reports) was seen in patients aged 40 to 49 years, corresponding to 30% of reports in this age range. Among patients aged 50 to 59 years, there were 779 BI-RADS 4 reports (35%). BI-RADS 5 reports were more common among patients aged 50 to 59 years (50 reports, 30%) and among patients aged 70 years or older (83 reports, 28%). CONCLUSIONS: The presence of a significant number of women between 40 and 49 years of age with a BI-RADS 4 mammography result stands out; being an opportunity to develop new clinical research and public health strategies within the framework of the Universal Health Care policy for breast cancer in Chile.

ABSTRACT

OBJETIVO: El cáncer de mama constituye la primera causa de muerte oncológica en mujeres chilenas. Las tasas de incidencia solo han sido estimadas según el registro 2003-2007. Nuestro objetivo fue estimar las tasas de incidencia en un período de 10 años en un servicio de salud y caracterizar dicha población. MÉTODO: Se calcularon las tasas de incidencia del período 2006-2015, por método directo, y se analizó la tendencia por Prais-Winsten. Se caracterizó la población según la edad y la etapa al diagnóstico. RESULTADOS: De 2862 casos, la tasa de incidencia estandarizada promedio fue de 66,6 por 100.000 mujeres. En el período hubo una tendencia al alza del diagnóstico de 0,63/100.000 anualmente (p = 0,5; intervalo de confianza del 95%: −1,73 a 2,99). La mayor tasa de incidencia bruta fue en el grupo de 70 y más años (154,8/100.000). El 49% correspondieron a casos diagnosticados de 50 a 69 años. El 56% se diagnosticó precozmente; la etapa I tuvo la más alta tasa (15,8/100.000). CONCLUSIONES: En este estudio, las tasas de incidencia son mayores que las reportadas en informes nacionales previos. El diagnóstico es mayoritariamente en etapas precoces, lo que difiere del resto de los países de la región. Nuestros datos pueden aportar a mejorar las políticas públicas.


OBJECTIVE: Breast cancer is the leading cause of cancer death in Chilean women. Incidence rates have only been estimated based on population records (2003-2007). Our objective was to estimate the incidence rates in a 10-year period in a health service and portray in words this cohort. METHOD: Incidence rates were calculated between 2006-2015 by direct method and trends were analyzed with the Prais-Winsten model. The population was defined according to age and stage at diagnosis. RESULTS: Of a total of 2862 cases, the average incidence rate was 66.6 out of 100,000 women. Between 2006-2015, the trend rose in breast cancer diagnosis of 0.63/100,000 annually (p = 0.5; 95% confidence interval: −1.73, 2.99). The highest crude rate of incidence was in the group aged 70 and over (154.8/100,000). 49% correspond to cases diagnosed between 50 and 69 years. 56% were in early stages, stage I, being the most frequent (15.8/100,000). CONCLUSIONS: On this research the incidence rates were higher than the ones reported on previous national reports. Diagnosis is mostly in early stages which differs from other countries in the region, our data can help improve public health policies.

ABSTRACT

Introducción: Cada año se producen en la región de las Américas más de 462 000 casos nuevos y casi 100 000 muertes por cáncer de mama. Objetivo: Describir los aspectos epidemiológicos del cáncer de mama en la población femenina del policlínico Emilio Daudinot Bueno. Métodos: Se realizó una investigación, descriptiva y retrospectiva en el municipio de Guantánamo en el período enero de 2014-diciembre de 2019. El universo lo constituyeron todas las mujeres del policlínico Emilio Daudinot Bueno con diagnóstico clínico y anátomopatológico de cáncer de mama (N = 83). Para la obtención de la información se aplicó un cuestionario cuyas variables recogían datos demográficos, factores de riesgo, elementos relacionados con el estado nutricional y hábitos tóxicos. Para el procesamiento de la información se hizo uso de la estadística descriptiva, utilizando medidas de resumen para variables cualitativas (frecuencias absolutas y porcentajes) y para variables cuantitativas (promedio). Resultados: Predominaron las edades comprendidas entre 50 y 60 años con edad promedio de 42,5 años, las pacientes con estado nutricional sobrepeso n = 41, seguidas de las obesas. El factor de riesgo más identificado fue no lactancia materna, y el hábito tóxico de mayor prevalencia fue el consumo de grasa animal. Conclusiones: Las mujeres con sobrepeso, el alto consumo de grasa animal y los antecedentes familiares de cáncer de mama, nuliparidad y no haber lactado, tienen una probabilidad mayor de desarrollar cáncer de mama, y más aún entre las edades comprendidas entre 50 y 60 años(AU)


Introduction: Every year, there are more than 462,000 new cases and almost 100,000 deaths due to breast cancer in the region. Objective: To describe the epidemiological aspects of breast cancer in the female population of Emilio Daudinot Bueno Polyclinic. Methods: A descriptive and retrospective research was carried out in Guantánamo Municipality in the period from January 2014 to December 2019. The universe was made up of all the women belonging to Emilio Daudinot Bueno Polyclinic with a clinical and anatomopathological diagnosis of breast cancer (N=83). To obtain the information, a questionnaire was applied, whose variables included demographic data, risk factors, as well as elements related to nutritional status and toxic habits. Descriptive statistics were used to process the information, using summary measures for qualitative variables (absolute frequencies and percentages) and for quantitative variables (average). Results: The predominant age group was between 50 and 60 years, with an average age of 42.5 years. There was also a predominance of patients with overweight [n=41], followed by obese patients. The most identified risk factor was not breastfeeding, while the most prevalent toxic habit was animal fat consumption. Conclusions: Overweight women, high animal fat consumption and family history of breast cancer, together with nulliparity and not having breastfed, accounts for a higher probability of developing breast cancer, and even more so at ages between 50 and 60 years(AU)

ABSTRACT

Abstract This study aimed to analyze the role of period, geographic and socio demographic factors in cancer-related mortality by prostate, breast, cervix, colon, lung and esophagus cancer in Brazilians capitals (2000-2015). Ecological study using data of Brazilian Mortality Information. Multilevel Poisson models were used to estimate the adjusted risk of cancer mortality. Mortality rate levels were higher in males for colon, lung and esophageal cancers. Mortality rates were highest in the older. Our results showed an increased risk of colon cancer mortality in both sexes from 2000 to 2015, which was also evidenced for breast and lung cancers in women. In both genders, the highest mortality risk for lung and esophageal cancers was observed in Southern capitals. Midwestern, Southern and Southeastern capitals showed the highest mortality risk for colon cancer both for males and females. Colon cancer mortality rate increased for both genders, while breast and lung cancers mortality increased only for women. The North region showed the lowest mortality rate for breast, cervical, colon and esophageal cancers. The Midwest and Northeast regions showed the highest mortality rates for prostate cancer.


Resumo Este estudo teve como objetivo analisar o papel de fatores temporais, geográficos e sociodemográficos na mortalidade por câncer de próstata, mama, colo do útero, cólon, pulmão e esôfago nas capitais brasileiras (2000-2015). Estudo ecológico utilizando informações brasileiras de mortalidade. Modelos de Poisson multinível foram usados ​​para estimar o risco ajustado de mortalidade por câncer. Os níveis de mortalidade foram maiores em homens para câncer de cólon, pulmão e esôfago. As taxas de mortalidade foram mais altas nos idosos. Nossos resultados mostraram risco aumentado de mortalidade por câncer de cólon em ambos os sexos de 2000 a 2015, o que também foi evidenciado para câncer de mama e de pulmão em mulheres. Em ambos os sexos, o maior risco de mortalidade para câncer de pulmão e esôfago foi observado nas capitais do Sul. As capitais do Centro-Oeste, Sul e Sudeste apresentaram o maior risco de mortalidade por câncer de cólon tanto para homens quanto para mulheres. A taxa de mortalidade por câncer de cólon aumentou para ambos os sexos, enquanto a mortalidade por câncer de mama e de pulmão aumentou apenas para as mulheres. A região Norte apresentou a menor taxa de mortalidade por câncer de mama, colo do útero, cólon e esôfago. As regiões Centro-Oeste e Nordeste apresentaram as maiores taxas de mortalidade por câncer de próstata.

ABSTRACT

The mortality of female breast cancer in Shandong Province has increased since the 1970. The differential decomposition analysis found that the slight decline in the crude mortality of breast cancer among women was entirely due to non-demographic factors during the 1970-1990, and the significant increase in the crude mortality was due to a combination of demographic and non-demographic factors since the 1990. The contribution rate of demographic factor has gradually increased from 53.5% in 2004-2005 to 59.5% in 2011-2013, while that of non-demographic factor has decreased from 46.5% to 40.5%. The women aged 45-64 years old were the major population of female breast cancer deaths, accounting for 40%-60% of total breast cancer deaths in different times, and then the mortality in female aged 55-64 years old increased rapidly, with increases of 52.12%, 115.19% and 29.01% in 2011-2013 over the 1970-1974, 1990-1992 and 2004-2005, respectively (Z=-7.342,P<0.001). Compared with 1970-1974, the age-standardized mortality rate of rural women increased by 41.86% in 2011-2013 (Z=-17.933, P<0.001), and that of urban women increased by 18.62% in 2011-2013 (Z=-25.642, P<0.001). The age-standardized mortality rate of breast cancer in urban women was higher than that in rural women in different times (all P<0.05). The spatial scan analysis found that eastern Shandong Province was found to be a sustained high-risk area for death, and other high-risk areas were transferred from north to southwest of Shandong between 1970 and 2013.

ABSTRACT

Objective: To understand the relationship between female breast cancer and occupational risk factors in Beijing, and provide scientific basis for the formulation of prevention strategies and measures. Methods: From June to December 2019, A 1: 1 case-control study was adopted, eight medical institutions in Beijing were selected as the research objects. Patients with breast cancer diagnosed by medical institutions were selected as case group and non breast cancer patients in the same medical institution as control group. A total of 973 subjects were included, including 495 in the case group and 478 in the control group. A one-to-one survey was conducted using a questionnaire uniformly compiled by the Beijing Centers for Disease Control and Prevention. The survey content mainly includes basic demographic characteristics and occupational risk factors. The Trait Coping Style Questionnaire (TCSQ) was used to investigate the corresponding methods, including two aspects: positive coping and negative coping. First, chi square test or Wilcoxon rank sum test were used for univariate analysis. Then Lasso regression was used to screen the risk factors of breast cancer. Finally, the risk factors were screened by multivariate logistic regression analysis. Results: Education lovel was 49.64%, body mass index (BMI) was 18.4~23.9 kg/m(2), accounting for 48.82%, marital status ws 84.48%. Compared with no night shift history, there was a significant increase in risk of breast cancer at night shift history (OR=1.70, 95% CI: 1.25~2.30, P<0.05) . Compared with most of the sitting posture and sometimes standing, the risk of breast cancer was increased, and the difference was statistically significant (OR=2.01, 95%CI: 1.40~2.90, P<0.05) . Conclusion: In the occupation risk factors, night shift work and working posture are related to the incidence of breast cancer in women, establishing a good schedule and avoiding long standing can effectively prevent and reduce the occurrence of breast cancer.

ABSTRACT

Resumo Este estudo transversal investigou a prevalência e os fatores associados ao diagnóstico de câncer de mama em estágio avançado entre 18.890 mulheres assistidas em hospital especializado da capital do Rio de Janeiro, Brasil, entre os anos 1999 e 2016. Utilizou-se regressão de Poisson com variância robusta para estimar razões de prevalência e respectivos intervalos de 95% de confiança. Apresentaram maiores prevalências de diagnóstico nessa condição mulheres com idade entre 20-39 e 40-49 anos, de raça/cor da pele preta e parda, que viviam sem companheiro(a), procedentes de outros municípios do estado do Rio de Janeiro, que tiveram o Sistema Único de Saúde como origem do encaminhamento e que foram diagnosticadas nos sexênios 1999-2004 e 2005-2010. Em contrapartida, mulheres com idade entre 60-69 e 70-99 anos, que cursaram algum nível de escolaridade, com histórico familiar de câncer e que chegaram ao hospital com diagnóstico e sem tratamento apresentaram menores prevalências de diagnóstico em estágio avançado. Esses resultados podem ser considerados no planejamento de ações de prevenção secundária, a fim de antecipar o diagnóstico de câncer de mama dos grupos mais vulneráveis e assim colaborar para a redução da prevalência do diagnóstico em estágio avançado.


Abstract This cross-sectional study investigated the prevalence and factors associated with advanced stage breast cancer diagnosis among 18,890 women assisted in a specialized hospital in the capital of Rio de Janeiro, Brazil, from 1999 to 2016. We used Poisson regression with robust variance to estimate prevalence ratios and respective 95% confidence intervals. The highest prevalence of diagnosis in this condition was in women aged 20-39 and 40-49 years, black and brown, living without a partner, from other cities of the state of Rio de Janeiro, who were referred by the Unified Health System and diagnosed in the 1999-2004 and 2005-2010 six-year periods. On the other hand, women aged 60-69 and 70-99 years, with some schooling level, with a family history of cancer and who arrived at the hospital with diagnosis and without treatment had lower prevalence of advanced stage breast cancer diagnosis. These results can be considered when planning secondary prevention actions to anticipate and, thus, collaborate to reduce the prevalence the breast cancer diagnosis in the most vulnerable groups.
