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

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.

ABSTRACT

This study aims to analyze inequalities in the incidence, mortality, and survival of the main types of cancer in women according to the Social Vulnerability Index (SVI). The study was conducted in Campinas, São Paulo State, Brazil, from 2010 to 2014, and used data from the Population-based Cancer Registry and the Mortality Information System. Incidence and mortality rates standardized by age and 5-year survival estimates were calculated according to the social vulnerability strata (SVS), based on the São Paulo Social Vulnerability Index. Three SVS were delimited, with SVS1 being the lowest level of vulnerability and SVS3 being the highest. Rate ratios and the concentration index were calculated. The significance level was 5%. Women in SVS1 had a higher risk of breast cancer (0.46; 95%CI: 0.41; 0.51), colorectal cancer (0.56; 95%CI: 0.47; 0.68), and thyroid cancer (0.32; 95%CI: 0.26; 0.40), whereas women from SVS3 had a higher risk of cervical cancer (2.32; 95%CI: 1.63; 3.29). Women from SVS1 had higher mortality rates for breast (0.69; 95%CI: 0.53; 0.88) and colorectal cancer (0.69; 95%CI: 0.59; 0.80) and women from SVS3 had higher rates for cervical (2.35; 95%CI: 1.57; 3.52) and stomach cancer (1.43; 95%CI: 1.06; 1.91). Women of highest social vulnerability had lower survival rates for all types of cancer. The observed inequalities differed according to the location of the cancer and the analyzed indicator. Inequalities between incidence, mortality, and survival tend to revert and the latter is always unfavorable to the segment of highest vulnerability, indicating the existence of inequality in access to early diagnosis and timely treatment.


O estudo teve como objetivo analisar desigualdades na incidência, mortalidade e sobrevida de câncer em mulheres de acordo com o Índice de Vulnerabilidade Social (IVS). O estudo foi realizado em Campinas, Estado de São Paulo, Brasil, no período de 2010 a 2014 e usou dados do Registro de Câncer de Base Populacional (RCBP) e do Sistema de Informação de Mortalidade (SIM). Foram calculadas as taxas de incidência e mortalidade padronizadas por idade e estimativas de sobrevida em cinco anos de acordo com estratos de vulnerabilidade social. Foram demarcados três estratos com base no IVS de São Paulo, onde o estrato 1 representava o nível de menor vulnerabilidade e o estrato 3 o de maior vulnerabilidade. Foram calculadas razões de taxas e índice de concentração, com nível de significância de 5%. Foram encontrados riscos mais elevados de câncer de mama (0,46; IC95%: 0,41; 0,51), colorretal (0,56; IC95%: 0,47; 0,68) e tireoide (0,32; IC95%: 0,26; 0,40) em mulheres do estrato 1 e de colo uterino em mulheres do estrato 3 (2,32; IC95%: 1,63; 3,29). Mulheres do estrato 1 tiveram taxas mais elevadas de câncer de mama (0,69; IC95%: 0,53; 0,88) e colorretal (0,69; IC95%: 0,59; 0,80), e mulheres do estrato 3 tiveram taxas mais elevadas de câncer do colo uterino (2,35; IC95%: 1,57; 3,52) e estômago (1,43; IC95%: 1,06; 1,91). Para todos os tipos de câncer, a sobrevida era mais baixa em mulheres do estrato de maior vulnerabilidade social. As desigualdades observadas mostraram diferenças de acordo com a localização do tumor e o indicador utilizado. Além disso, há uma tendência de inverter as desigualdades entre incidência, mortalidade e sobrevida, onde a sobrevida sempre é desfavorável para o estrato de maior vulnerabilidade, indicando a existência de desigualdades em acesso ao diagnóstico precoce e tratamento precoce.


El objetivo fue analizar las inequidades en la incidencia, mortalidad y supervivencia de los principales tipos de cáncer en mujeres, según el Índice de Vulnerabilidad Social (IVS). El estudio se llevó a cabo en Campinas, estado de São Paulo, Brasil, durante el período 2010-2014, y se usaron datos del Registro de Cáncer de Base Poblacional (RCBP) y el Sistema de Información de Mortalidad (SIM). Las tasas de incidencia y mortalidad estandarizadas por edad, así como las estimaciones de supervivencia durante cinco años, se calcularon según los estratos de vulnerabilidad social (SVS). Se delimitaron tres SVS, basados en el IVS de São Paulo, con SVS1 siendo el nivel más bajo de vulnerabilidad y SVS3 siendo el nivel más alto de vulnerabilidad. Se calcularon los cocientes de tasas y el índice de concentración. El nivel de significancia fue 5%. Se encontró un riesgo más alto de cáncer de la mama (0,46; IC95%: 0,41; 0,51), colorrectal (0,56; IC95%: 0,47; 0,68), y tiroides (0,32; IC95%: 0,26; 0,40) en mujeres de SVS1, y cáncer cervical en mujeres de SVS3 (2,32; IC95%: 1,63; 3,29). Respecto a la mortalidad, las mujeres de SVS1 tuvieron tasas más altas en cáncer de la mama (0,69; IC95%: 0,53; 0,88) y colorrectal (0,69; IC95%: 0,59; 0,80) y las mujeres de SVS3 tuvieron tasas más altas en cáncer cervical (2,35; IC95%: 1,57; 3,52) y estómago (1,43; IC95%: 1,06; 1,91). Para todos los tipos de cáncer, las tasas de supervivencia fueron más bajas en mujeres del estrato social con más alta vulnerabilidad social. Las inequidades sociales observadas difirieron según la localización del cáncer y el indicador analizado, y no hubo una tendencia para revertir las inequidades entre incidencia, mortalidad y supervivencia, las últimas siempre fueron desfavorables para el segmento de más alta vulnerabilidad, indicando la existencia de desigualdad en el acceso a un diagnóstico temprano y un tratamiento oportuno.

ABSTRACT

Abstract Objective The present study aims to assess the feasibility and patient satisfaction of teleoncology orientation in a vulnerable population of breast cancer patients assessed in a government health system during the coronavirus pandemic in 2020. Methods Eligible patients received an invitation to receive remote care to minimize exposure to an environment in which the risk of respiratory infection was present. The means of communication was telephone through an application that allows free conversation with no charge. An anonymous-response questionnaire based on a Likert-type scale was sent through a cell phone application or e-mail directly to each patient or close relative of the patient immediately after teleconsultation. Responses to the questions, which addressed utility, facility, interface quality, interaction quality, reliability, satisfaction, and interest in future evaluation, were compiled and analyzed. Results A total of 176 eligible patients scheduled for consultation were evaluated and 98 were included. Seventy (71.4%) successfully undertook the teleorientation. The questionnaire was submitted by 43 (61.4%) patients. The overall teleoncology orientation was classified as very positive by 41 (95.3%) patients. Specifically, regarding the questionnaire items, 43 (100%) patients scored 4 or 5 (agreed that the teleconsultation was beneficial) concerning the facility, followed by 42 (97.2%) for the interface quality, 41 (95.3%) for both utility and interaction quality, 40 (93%) for satisfaction and interest in future evaluation, and, finally, 39 (90.6%) for reliability. Conclusion Teleoncology orientation of low-income breast cancer patients is most feasible and leads to high patient satisfaction.

ABSTRACT

Introducción: El cáncer de mama se ha convertido en un verdadero desafío a la calidad y expectativa de vida de la población mundial, con un aumento considerable en su incidencia y prevalencia. Cuba cuenta, desde 1987, con un Programa de Control de Cáncer Mamario. Objetivo: Ejemplificar el estudio de un caso con linfoma no Hodgkin primario de la mama, su cuadro clínico y los medios diagnósticos utilizados. Caso clínico: Paciente femenina de 70 años de edad, color de la piel negra, que acudió al Consultorio Médico de la Familia por presentar malestar general, molestias y aumento de volumen en la mama derecha. Se le remitió a consulta de cirugía y se le realizaron estudios complementarios. Se detectó nódulo de mediana densidad, contornos parcialmente definidos, distorsión del tejido vecino, otros nódulos de menos tamaño y densidad en el cuadrante inferior interno, calcificaciones vasculares en ambas mamas. Una biopsia corrobora linfoma no Hodgkin difuso de células grandes de alto grado. Conclusiones: El linfoma primario no Hodgkin de mama es muy raro y de difícil diagnóstico clínico porque no se dispone de signos, síntomas o criterios de imagen específicos para ello. El autoexamen de mama continúa siendo el principal método de diagnóstico del cáncer de mama y aunque el examen clínico, el ultrasonido de mama y la mamografía apoyan la presunción, es la biopsia quien solo brinda la confirmación diagnóstica precisa(AU)


Introduction: Breast cancer has become a real challenge to the quality of life and to life expectancy of the world population, with a considerable increase in its incidence and prevalence. Cuba has, since 1987, a breast cancer control program. Objective: To present a case with primary non-Hodgkin's lymphoma of the breast in a 70-year-old patient, its clinical picture and the diagnostic means used. Clinical case: 70-year-old female patient, with black skin, who came to the family medical office due to malaise, discomfort and increased volume in her right breast. She was referred to surgery and complementary studies were performed. Nodule of medium density was identified, with partially defined contours, distortion of the neighboring tissue, together with other nodules of less size and density in the lower internal quadrant, and vascular calcifications in both breasts. A biopsy confirms diffuse high-grade large-cell non-Hodgkin's lymphoma. Conclusions: Primary non-Hodgkin's lymphoma of the breast is very rare and difficult to diagnose clinically because there are no specific signs, symptoms or imaging criteria for it. Breast self-examination continues to be the main method of diagnosis for breast cancer and, although clinical examination, breast ultrasound and mammography support such diagnostic presumption, it is the biopsy that only provides the precise diagnostic confirmation(AU)

ABSTRACT

Introducción: El cáncer de mama es el tumor maligno más frecuente en el mundo, en Cuba, es la segunda causa de muerte en mujeres. La insuficiencia en el diagnóstico precoz y la existencia de novedosas estrategias de tratamiento plantean la necesidad de establecer formas eficaces para identificar el riesgo en personas sanas, sin embargo en nuestro país no se cuenta con un método eficaz para predecir el riesgo y direccionar las acciones preventivas y terapéuticas. Objetivo: Crear un estándar nacional orientado a la identificación del cáncer de mama como soporte a la práctica médica y como herramienta de apoyo en la evaluación del riesgo. Método: Se combinaron 28 variables (determinadas por los factores de riesgo de cáncer de mama) a las cuales se les atribuyeron parámetros de ponderación asociados al nivel de incidencia registrado en la literatura médica, utilizando un algoritmo de votación como elemento matemático central. Resultados: Se desarrolló un sistema computarizado para la evaluación del riesgo de cáncer de mama en personas sanas. Conclusiones: BRCAR es una herramienta de soporte para objetivar el riesgo del cáncer de mama, al determinar el impacto de determinados factores de riesgo, con el fin de direccionar los métodos de estudio para la detección precoz(AU)


Introduction: Breast cancer is the most frequent malignant tumour in the world; it is the second cause of women death in Cuba. The insufficiency in early diagnosis and the existence of novel treatment strategies raise the need to establish effective ways to identify risk in healthy people, however in our country there is no effective method to predict risk and direct preventive actions and therapeutic. Objective: To create a national standard aimed at identifying breast cancer as a support to medical practice and support tool in risk assessment. Method: 28 variables (determined by risk factors for breast cancer) were combined; assigning to those variables weighting parameters associated with the level of incidence recorded in the medical literature, using a voting algorithm as the central mathematical element. Results: A computerized system was developed to assess the risk of breast cancer in healthy people. Conclusions: BRCAR is a support tool to objectify the risk of breast cancer, by determining the impact of certain risk factors, in order to direct study methods for early detection(AU)

ABSTRACT

Resumen Introducción: Promover la detección de cáncer de mama (CaMa) en mujeres mediante mastografía es una estrategia viable para disminuir los diagnósticos en fases clínicamente avanzadas y la mortalidad. Objetivos: Describir los resultados reportados por estudios de mastografía en mujeres realizados a nivel nacional durante 2013-2017 y analizar la tendencia espaciotemporal de categorías BIRADS (Breast Imaging Reporting and Data System) sugestivas de malignidad por Estado. Método: Diseño analítico longitudinal que incluyó información sobre estudios de mastografía de mujeres según grupo de edad (< 40 e ≥ 40), valoradas en unidades de la Secretaría de Salud, México, durante 2013-2017. Se estimó la frecuencia de categorías según BIRADS, tasa estandarizada sugestiva de malignidad (categorías 4 y 5) en mujeres ≥ 40 años y se utilizó estadística espacial para analizar la tendencia por Estado. Resultados: Se analizaron 3,659,151 mastografías, el 98.5 % en mujeres ≥ 40 años. La tasa sugestiva de malignidad disminuyó de 38.3 (2013) a 31 (2017) por 100 mil mujeres ≥ 40 años; sin embargo, el riesgo de detección aumentó hasta 13 veces en diez Estados. Conclusiones: Aunque el riesgo de detección en categorías sugestivas de malignidad disminuyó a nivel nacional, algunos Estados requieren reforzar la aplicación de programas de detección del CaMa mediante mastografía e incrementar la participación de la población blanco.


Abstract Introduction: Promoting breast cancer (BC) detection in women by means of mammography is a viable strategy to reduce the number of diagnoses at clinically advanced stages and mortality. Objectives: To describe the results reported by mammography studies in women, carried out nationally during 2013-2017, and to analyze the spatiotemporal trend of Breast Imaging Reporting and Data System (BIRADS) categories suggestive of malignancy by State. Method: Longitudinal, analytical design that included information on mammography studies of women according to age group (< 40 and ≥ 40), evaluated in units of the Ministry of Health of Mexico during 2013-2017. The frequency of BIRADS categories and a standardized rate suggestive of malignancy (categories 4 and 5) were estimated in women aged ≥ 40 years, and spatial statistics were used to analyze the trend by State. Results: A total of 3,659,151 mammograms were analyzed, 98.5 % in women aged ≥ 40 years. The malignancy-suggestive rate decreased from 38.3 (2013) to 31 (2017) per 100,000 women aged ≥ 40 years; however, the risk of detection increased up to 13 times in ten States. Conclusions: Although the risk of detection in categories suggestive of malignancy decreased at the national level, some States need to reinforce the application of BC detection programs through mammography and increase the participation of the target population.

ABSTRACT

BACKGROUND@#Female breast cancer (FBC) has become the most prevalent malignancy worldwide. We aimed to evaluate the global and regional burden in epidemiological trends and factors associated with the incidence and mortality of FBC.@*METHODS@#FBC incidence and mortality in 60 selected countries by cancer registry data integrity in 2020 were estimated from the GLOBOCAN database, and their association with the human development index (HDI) was further evaluated. Trends of age-standardized rates of incidence and mortality in 60 countries from 2000 through 2019 were evaluated by joinpoint regression analysis using data of Global Burden of Disease 2019. The association between potential behavioral, metabolic, and socioeconomic risk factor exposure at the nation level retrieved from the World Bank and Global Health Observatory and the incidence and mortality of FBC were evaluated by multivariate linear regression.@*RESULTS@#FBC incidence and mortality varied greatly in the 60 included countries. Higher incidence and mortality rates were typically observed in countries with higher HDIs and vice versa. During 2000 to 2019, significantly increasing trends in incidence and mortality were observed in 26 (average annual percent changes [AAPCs], 0.35-2.96) and nine countries (AAPC, 0.30-1.65), respectively, while significantly decreasing trends in both incidence and mortality were observed in 22 countries, most of which were high-HDI countries. Among the population aged ≥40 years, there were 26 and 11 countries showing significantly increased trends in incidence and mortality, respectively. Ecological analysis showed that countries with higher prevalence rates of high cholesterol and higher health expenditures were more likely to have higher FBC incidence, and countries with higher rates of obesity and poorer universal health coverage were more likely to have higher FBC mortality.@*CONCLUSIONS@#Despite decreased or stabilized FBC incidence and mortality rates were observed in some countries with high HDI over the past decades, disease burden became even severer in developing countries, especially for the population aged ≥40 years. Effective targeted preventive programs are strongly encouraged to reduce the FBC disease burden worldwide.

ABSTRACT

BACKGROUND@#Pregnancy-associated breast cancer (PABC) is a special type of breast cancer that occurs during pregnancy and within 1 year after childbirth. With the rapid social development and the adjustment of reproductive policies in China, the average age of females at first childbirth is increasing, which is expected to lead to an increase in the incidence of PABC. This study aimed to accumulate clinical experience and to investigate and summarize the prevalence, diagnosis, and treatment of PABC based on large multicenter samples in China.@*METHODS@#According to the Chinese Society of Breast Surgery, a total of 164 patients with PABC in 27 hospitals from January 2016 to December 2018 were identified. The pregnancy status, clinicopathological features, comprehensive treatment methods, and outcomes were retrospectively analyzed. Survival curves were plotted using the Kaplan-Meier method.@*RESULTS@#A total of 164 patients of PABC accounted for 0.30% of the total number of cases in the same period; of which, 83 patients were diagnosed during pregnancy and 81 patients during lactation. The median age of PABC was 33 years (24-47 years). Stage I patients accounted for 9.1% (15/164), stage II 54.9% (90/164), stage III 24.4% (40/164), and stage IV 2.4% (4/164). About 9.1% (15/164) of patients were luminal A. Luminal B patients accounted the most (43.3% [71/164]). About 15.2% (25/164) of patients were human epidermal growth factor receptor 2 (Her-2) overexpression and 18.9% (31/164) of patients were triple-negative breast cancer. For pregnancy breast cancer, 36.1% (30/83) of patients received direct surgery and 20.5% (17/83) received chemotherapy during pregnancy. About 31.3% (26/83) chose abortion or induction of labor. The median follow-up time was 36 months (3-59 months); 11.0% (18/164) patients had local recurrence or distant metastasis and 3.0% (5/164) died.@*CONCLUSIONS@#It is safe and feasible to standardize surgery and chemotherapy for PABC.

ABSTRACT

ABSTRACT Objective To evaluate the impact of COVID-19 pandemic on breast cancer diagnosis in a breast imaging center. Methods This was a retrospective cohort study that included women submitted to breast exams and procedures in a private hospital in São Paulo, SP, Brazil, as from the period of most strict social isolation measures, in 2020 (separated in first period of social isolation, March 24 to June 21, 2020, and second period, June 22 to December 31, 2020), as compared to the same period in 2019. The number of exams, cancer detection rates, pathologic findings and risk factors were analyzed. Results A total of 32,144 patients were included in the study. Breast imaging exams and procedures decreased by 78.9% in the first period, and 2.7% in the second period, in 2020. By the end of 2020, the number of breast cancer lesions detected was just six cases less than in 2019, although the number of patients submitted to mammograms was 35% lower. Conclusion There was a drop in number of breast exams and cancer diagnoses in the first 90 days of the pandemic. The decrease in diagnosis of cancer was partially compensated in the second period, but the number of patients submitted to mammograms by the end of 2020 was lower, still considering a large number of patients with delayed exams.


RESUMO Objetivo Avaliar o impacto da pandemia da COVID-19 no diagnóstico de câncer de mama em um centro de imagem de mama. Métodos Estudo de coorte retrospectivo que incluiu mulheres submetidas a exames e procedimentos de mama em um hospital privado em São Paulo, SP, Brasil, no período de medidas mais rigorosas de isolamento social em 2020 (dividido em primeiro período, de 24 de março a 21 de junho de 2020, e em segundo período, de 22 de junho a 31 de dezembro de 2020), comparado com o mesmo período de 2019. Foram analisados o número de exames, as taxas de detecção de câncer, os achados patológicos e os fatores de risco. Resultados Foram incluídas 32.144 pacientes. Os exames e os procedimentos de imagem da mama em 2020 tiveram redução de 78,9% no primeiro período e 2,7% no segundo período. Ao final de 2020, foram diagnosticadas com câncer de mama seis pacientes a menos do que em 2019, embora o número de pacientes submetidas à mamografia tenha sido 35% menor. Conclusão Houve queda no número de exames de mama e de diagnósticos de câncer nos primeiros 90 dias da pandemia. A redução dos diagnósticos de câncer foi parcialmente compensada no segundo período, mas o número de pacientes submetidas a exames de mamografia até o final do ano foi menor, considerando ainda um grande número de pacientes com exames atrasados.

ABSTRACT

ABSTRACT OBJECTIVE: To report the decrease in breast imaging after covid-19 pandemic, obtaining the number of mammograms performed in 2019 and 2020. Additionally, to investigate if there was an increase in the proportion of women undergoing mammography for diagnostic purposes, with palpable lesions. METHOD: This is a cross-sectional study, based on the number of mammograms performed by the Brazilian public health services, provided by DATASUS, an open access database. Mammograms from private institutions were not included. This study compares the number of mammograms performed in 2019 and 2020, in women aged 50-69 years, stratified by month, in each federal state, and the presence of palpable lumps (physician-reported). RESULTS: In total, 1,948,471 mammograms were performed in 2019 and 1,126,688 in 2020, for the population studied. These values represent a 42% decline. Monthly, a significant decreased is observed after April 2020. The results varied slightly according to federal state; yet the entire country was affected. Rondônia was the most affected state, with 67% decline. The proportion of women presenting palpable lumps increased from 7.06% on average in 2019 to 7.94% in 2020 (OR = 1.135, 95%CI 1.125-1.145, p = 0,001). DISCUSSION: The number of mammograms performed in 2020 declined considerably. Out of the women who presented for mammogram, the proportion of palpable lumps was significantly higher in 2020. Considering the detection rate of digital mammography, the loss of 800,000 exams means 4,000 undiagnosed breast cancer cases, by the end of 2020.

ABSTRACT

Abstract Objective To evaluate the distribution of the main sociodemographic and clinicalpathological characteristics in women with breast cancer according to the molecular profile by immunohistochemistry. Methods A cross-sectional, retrospective, analytical and quantitative study was performed, with an analysis of 137 medical records from January 2015 to December 2018 of women attending the High Complexity in Oncology Unit of the city of Imperatriz, state of Maranhão, Brazil. The immunohistochemical profile of tumors based on the estrogen and progesterone receptor, Human Epidermal growth factor Receptor-type 2 (HER2) overexpression and Ki67 cell proliferation indexwas defined, fromwhich six molecular subtypes were determined: luminal A, luminal B-HER2 negative, luminal B-HER2 positive, triple negative, overexpression of HER2 and inconclusive. Results A total of 52.6% of the patients were postmenopausal, mean age 52.1 years old, brown (56.2%), had a schooling level < 9 years (40%), staging > IIB (52.6%) and 23.4% hadmetastasis. Invasive ductal carcinoma accounted for 84.7%, tumor size was 2 to 5 cm (48.9%), with lymph node involvement (56.2%), axillary lymphadenectomy in 67.2%, andmastectomy in 73.7% of the patients. Themost frequentmolecular subtype was the luminal B-HER2 negative (36.5%), and the luminal A subtype showed characteristics of better prognosis when compared with the others. Conclusion It was concluded that in the association of molecular subtypes with sociodemographic and clinical-pathological characteristics, there were no statistically significant results obtained, except for complementary therapy, referring to hormone therapy, and there was a high index of metastasis at diagnosis, which was a worrying factor and indicative of failures in the screening and early diagnosis of this population.


Resumo Objetivo Avaliar a distribuição das principais características sociodemográficas e clínico-patológicas em mulheres com câncer de mama segundo o perfil molecular pela imunohistoquímica. Métodos Estudo transversal, retrospectivo, analítico, descritivo e quantitativo, com análise de 137 prontuários do período de janeiro de 2015 a dezembro de 2018 de mulheres atendidas na Unidade de Assistência da Alta Complexidade em Oncologia da cidade de Imperatriz, MA, Brasil. Foi definido o perfil imunohistoquímico dos tumores baseado na avaliação dos receptores de estrogênio e progesterona, superexpressão de HER2 e índice de proliferação celular Ki67, de onde foram determinados seis subtipos moleculares: luminal A, luminal B-HER2 negativo, luminal B-HER2 positivo, triplo negativo, superexpressão de HER2 e inconclusivo. Resultados Foi demonstrado que 52,6% das pacientes eram pós-menopausadas, com idademédia de 52,1 anos, pardas (56,2%), tinhamgrau de escolaridade < 9 anos (40%), estadiamento > IIB (52,6%) e 23,4% tinham metástase. Carcinoma ductal invasivo representou 84,7%, o tamanho tumoral foi de 2 a 5 cm (48,9%), com comprometimento linfonodal (56,2%), com linfadenectomia axilar em 67,2% e mastectomia em 73,7% das pacientes. O subtipo molecularmais frequente foi o luminal B-HER2 negativo (36,5%), e o subtipo luminal A apresentou características de melhor prognóstico em relação aos demais. Conclusão Concluiu-se que na associação dos subtipos moleculares com as características sociodemográficas e clínico-patológicas não se obteve resultados com significância estatística, exceto para terapia complementar, referente à hormonioterapia, e houve elevado índice de metástase ao diagnóstico, o que representou um fator preocupante e indicativo de falhas no rastreio e diagnóstico precoce dessa população.

ABSTRACT

Resumen Objetivo: Establecer la prevalencia de mujeres mayores de 50 años con mamas densas estudiadas por mamografía en el área de Bucaramanga. Métodos: Se realizó un estudio descriptivo retrospectivo durante el periodo comprendido entre enero de 2014 y agosto de 2015, en el que se revisaron 10.110 mamografías de pacientes mayores de 50 años. Posteriormente, se hizo una revisión de la literatura en las principales bases de datos. Resultados: De las 10.110 mamografías realizadas, 4.448 fueron encontradas como positivas para mama densa. De estas, el 39,69% correspondió a tejido mamario heterogéneamente denso y el 4,29%, a tejido mamario extremadamente denso, para un total de 43,9% de los casos estudiados. Conclusión: La densidad mamaria es un factor de riesgo independiente de cáncer de mama, considerado de mediana importancia frente a otros factores. A medida que incrementa la densidad mamaria, se genera la superposición del tejido mamario radio-opaco que puede ocultar y llegar a retardar el diagnóstico de un cáncer subyacente. Dada la alta prevalencia de tejido mamario denso encontrado en la población estudiada, se sugiere complementar el tamizaje con otros métodos de imágenes.


Abstract Objective: To establish the prevalence of dense breast tissue in a group of women aged over 50 years, who were studied with mammography in the city of Bucaramanga (Colombia). Methods: A retrospective descriptive study was conducted from January 2014 to August 2015; 10.110 mammograms of patients aged over 50 years were reviewed. Subsequently, a review of the literature in the main databases was made. Results: From 10.110 mammograms that were performed, 4.448 were found to be positive for dense breast tissue. 39,69% had heterogeneously dense breast tissue, and 4,29% extremely dense breast tissue, for a total result of 43,9% patients with positive dense breast tissue. Conclusion: Breast density is an independent risk factor for breast cancer, being of medium importance compared with other factors. As the breast density increases, the overlap of the radiopaque breast tissue that can hide and delay the diagnosis of an underlying cancer is generated. The high prevalence of dense breast tissue that we found in this population suggests the need of complementing screening with other imaging methods.

ABSTRACT

Resumen Colombia tiene un riesgo intermedio a desarrollar cáncer de mama con una tasa de incidencia estandarizada por edad en de 44,1 por 100.000 mujeres. A pesar de que en el país se recomienda la tamización mediante mamografía, en mujeres de 50 a 69 años y examen clínico de mama anual, así como detección temprana para mujeres sintomáticas independientemente de la edad; en Colombia no se ha podido reducir la mortalidad por esta causa. Múltiples causas parecen explicar este problema: baja participación en las actividades de tamización con mamografía por parte de la población objeto; baja calidad de la mamografía, y barreras de acceso para el diagnóstico oportuno y el tratamiento integral. Frente a esta problemática el 3 de octubre fue aprobado en primer debate el proyecto de ley 259 de 2019 Cámara Proyecto de Ley "Por medio de la cual se establecen medidas para la prevención, diagnóstico, tratamiento oportuno, rehabilitación, y cuidados paliativos del cáncer de mama y se dictan otras disposiciones". A fin de revisar el soporte científico del contenido del proyecto de ley y aportar a su adecuada discusión, el Instituto Nacional de Cancerologia (INC) realizó un foro el 9 de diciembre de 2019. El propósito de este artículo es presentar el análisis de los puntos de mayor controversia desde una perspectiva científica, como base para la adecuada toma de decisiones en materia de políticas de salud pública.


Abstract Colombia ranks at an intermediate risk level regarding the development of breast cancer, with an age-standardized incidence rate of 44.1 per 100,000 women. Although mammography screening and annual Clinical Breast Examination for women aged 50 to 69 are recommended in Colombia, as well as early detection for symptomatic women regardless of age, mortality from this cause has not been reduced in Colombia. Multiple causes seem to explain this problem: low participation of the target population in mammography screening activities, poor quality of mammography, and access barriers for timely diagnosis and comprehensive treatment. In view of this problem, the House of Representatives approved in first debate last October 3 Bill No. 259 of 2019 "by means of which measures and other provisions for prevention, diagnosis, timely treatment, rehabilitation, and palliative care of breast cancer are set up". The Colombian National Cancer Institute INC, held a forum on December 9, 2019, aimed at reviewing the scientific support of the content of the bill and contribute to its proper discussion. The purpose of this paper is to present the analysis of the most controversial points from a scientific perspective, as a basis for appropriate decision-making in public health policy.

ABSTRACT

ABSTRACT BACKGROUND: The largest radiological accident to occur in any urban area happened in Goiânia, Brazil, in 1987. OBJECTIVE: To evaluate the association between breast cancer incidence and ionizing radiation levels. DESIGN AND SETTING: Ecological study among residents of the city of Goiânia, Brazil. METHODS: The central region of Goiânia, with seven major sources of contamination from cesium-137, was defined as the study area. The addresses of women diagnosed with breast cancer were identified between 2001 and 2010. The data were geographically referenced and, using census data, the annual averages of crude incidence rates were estimated. The existence of clusters of new cases was ascertained by means of the Moran index. Correlations of radiometric measurements with the incidence were assessed using unconditional linear regression. RESULTS: A total of 4,105 new cases were identified, of which 2,233 were in the study area, and of these, 1,286 (57.59%) were georeferenced. The gross rates of total and referenced cases were 102.91 and 71.86/100,000 women, respectively. These were close to the average for Brazilian state capitals, which is 79.37/100,000 women. The cluster analysis showed slight correlations in three small sets of census tracts, but these were far from the sources of contamination. The scatter plot of points and the R2 value close to zero indicated that there was no association between the variables. CONCLUSION: This study reinforces the hypothesis that the ionizing radiation levels to which women living in Goiânia are now exposed to are not associated with the onset of new cases of breast cancer.

ABSTRACT

RESUMEN Introducción: El cáncer de mama es el tumor maligno más frecuente entre las mujeres de todo el mundo. Considerando los dos sexos, es el segundo en frecuencia después del cáncer de pulmón. En Cuba, sigue siendo la neoplasia maligna que más se diagnóstica en mujeres. Se estima que una de cada 9 a 12 mujeres con factores de riesgo padecerá la enfermedad a lo largo de su vida en los países del mundo occidental. Objetivo: Profundizar acerca de los factores de riesgo asociados al cáncer de mama. Métodos: Se realizó una revisión bibliográfica temática, observacional y retrospectiva de 25 artículos en el período comprendido desde septiembre 2018 a enero 2019. Se accedió a las bases de datos de Scielo. La búsqueda se hizo en artículos nacionales e internacionales, con textos completos, estos se sometieron a una lectura crítica utilizando métodos teóricos (análisis histórico-lógico y análisis-síntesis) y empíricos (análisis documental). Conclusiones: Se evidenció que el sexo femenino, la edad, el sobrepeso, la obesidad, el tabaquismo, el alcoholismo, el color de la piel, los antecedentes heredofamiliares de cáncer, la edad de la menarquía, la edad de la menopausia, los antecedentes de enfermedades benignas de la mama, el uso de tratamiento de reemplazo hormonal, la cantidad de hijos, el tiempo de lactancia materna y la actividad física, entre otros, constituyen factores de riesgo predisponentes al cáncer de mama, de ahí la importancia del reconocimiento de estos para la prevención y el diagnóstico precoz.


ABSTRACT Introduction: Breast cancer is the most frequent malignant tumor among women worldwide. Considering the two sexes, it is the second in frequency, after lung cancer. In Cuba, it is still the malignant neoplasm that is most diagnosed in women. It is estimated that one in 9 to 12 women with risk factors will suffer the disease throughout their lives in countries of the western world. Objective: To elaborate on the risk factors associated with breast cancer. Methods: A thematic, observational and retrospective bibliographic review of 25 articles was carried out in the period from September 2018 to January 2019. We accessed the Scielo databases. The search was performed in national and international articles, with full texts, which were subjected to critical reading using theoretical (historical-logical analysis and analysis-synthesis) and empirical (documentary analysis) methods. Conclusions: Evidenced showed that the female sex, age, overweight, obesity, smoking, alcoholism, skin color, hereditary family history of cancer, age of menarche, age of menopause, history of benign breast diseases, the use of hormone replacement treatment, the number of children, the time of breastfeeding, physical activity, among others, are risk factors predisposing to breast cancer; hence the importance of recognizing them for prevention and early diagnosis.
