ABSTRACT

Objective. To analyze whether the COVID-19 pandemic had an impact on the screening, diagnosis and treatment of breast cancer in women up to 50 years of age in the state of Pará. Methods. Retrospective, cross-sectional study with a quantitative approach, using data from the Information Technology Department of the Brazilian Unified Health System. (DATASUS). The number of exams carried out in the pre-pandemic (2018-2019) and pandemic (2020-2021) period was analyzed based on the percentage variation, application of the chi-square test and G test for the time of exams and start time of treatment. Results. During the pandemic period, there was a greater number of screening mammograms (+3.68%), cytological (+23.68%), histological (+10.7%) and a lower number of diagnostic mammograms (-38.7%). The time interval for carrying out the exams was up to 30 days for screening and diagnostic exams and more than 60 days to start treatment during the pandemic period. Conclusion. Although the results indicate an increase in the number of screening and diagnostic procedures for breast cancer during the pandemic period, with the exception of diagnostic mammography, when considering probability values, the study points out that statistically the COVID-19 pandemic did not interfere with actions of breast cancer, in women over 50 years of age, in the state of Pará. Considering the autonomy of nursing and its role in public health, it is up to the professionals who are in charge of primary care programs to implement contingency plans in periods of crisis so that the population is not left unassisted.


Objetivo. Analizar si la pandemia de COVID-19 tuvo impacto en el tamizaje, diagnóstico y tratamiento del cáncer de mama en mujeres de 50 años y más del Estado do Pará-Brasil. Métodos. Estudio retrospectivo, transversal, con abordaje cuantitativo, en el que se utilizaron los datos del Departamento de Informática del Sistema Único de Salud de Brasil (DATASUS). Se comparó el número de exámenes realizados y el tiempo para el inicio de tratamiento en los períodos prepandémico (2018-2019) y pandémico (2020-2021). Resultados. Se observó un mayor número de mamografías de cribado (+3.68%), citologías (+23.68%) e histologías (+10.7%) y un menor número de mamografías diagnósticas (-38.7%) en el período pandémico. El tiempo para la realización de las pruebas fue de hasta 30 días para el cribado y diagnóstico y de más de 60 días para el inicio del tratamiento durante el período pandémico. Conclusión. Aunque los resultados indican un aumento del número de procedimientos de cribado y diagnóstico del cáncer de mama en el periodo pandémico, con la excepción de la mamografía diagnóstica, cuando consideramos los valores de p) el estudio muestra que la pandemia COVID-19 estadísticamente no interfirió en las acciones preventivas contra el cáncer de mama en mujeres de 50 años y más en el estado de Pará. Teniendo en cuenta la autonomía de la enfermería y su papel en la salud pública, corresponde a los profesionales responsables de los programas de atención primaria implementar planes de contingencia en tiempos de crisis para no dejar desatendida a la población.


Objetivo. Analisar se a pandemia da COVID-19 repercutiu no rastreamento, diagnóstico e tratamento do câncer de mama em mulheres paraenses a partir de 50 anos. Métodos. Estudo retrospectivo, transversal, de abordagem quantitativa, com utilização de dados do Departamento de Informática do Sistema Único de Saúde brasileiro. (DATASUS). Analisou-se o número de exames realizados no período pré-pandemia (2018-2019) e pandêmico (2020-2021) com base na variação percentual, aplicação do teste qui quadrado e teste G para o tempo de realização de exames e tempo de início de tratamento. Resultados. Observou-se no período pandêmico maior quantitativo de mamografias de rastreamento (+3.68%), citológicos (+23.68%), histológicos (+10.7%) e menor registro de mamografias diagnósticas (-38.7%). O intervalo de tempo para realização dos exames foi de até 30 dias para os exames de rastreamento e diagnóstico e tempo maior que 60 dias para início de tratamento no período pandêmico. Conclusão. Embora os resultados indiquem aumento no quantitativo de procedimentos de rastreamento e diagnósticos para o câncer de mama no período pandêmico, com exceção da mamografia diagnóstica, ao considerarmos os valores de probabilidade, o estudo aponta que estatisticamente a pandemia da COVID-19 não interferiu nas ações do câncer de mama, em mulheres a partir de 50 anos, no Estado do Pará. Considerando a autonomia da enfermagem e sua atuação na saúde pública, cabe aos profissionais que estão à frente dos programas da atenção básica implementar planos de contingência em períodos de crise para que a população não fique desassistida.

ABSTRACT

Introdução: A reconstrução mamária pós-tratamento cirúrgico do câncer de mama (um dos principais cânceres que acometem as mulheres) tem sido progressivamente mais indicada, haja vista o benefício da recuperação psicológica e da qualidade de vida, seja utilizando implantes e/ou tecidos autólogos. O presente trabalho visa demonstrar a experiência da equipe, discutir técnicas operatórias e complicações em relação aos dados da literatura mundial, além de verificar a aplicabilidade da técnica na prática clínica da equipe. Método: Estudo observacional retrospectivo desenvolvido em hospital universitário em Juiz de Fora a partir da revisão de prontuários de pacientes submetidas a mastectomia com reconstrução mamária entre 2010 e 2020. Resultados: Das 860 mamas abordadas, 84% foram imediatas à cirurgia oncológica e 16% foram tardias; o principal acesso ao tecido mamário foi a incisão de Stewart, seguido de incisões inframamárias estendidas, periareolares e T invertido; quanto às técnicas reconstrutoras, destaca-se 35% dos casos com retalho com músculo grande dorsal, 25% com prótese pré-peitoral, 20% com retalho miocutâneo transverso do músculo reto abdominal e 10% com retalho muscular local. As complicações mais incidentes foram deiscência de sítio cirúrgico, seguida de necrose cutânea, seroma, infecção de sítio cirúrgico e hematoma, além de outros menos comuns como dor crônica e ruptura de prótese após mamografia. Conclusão: A reconstrução mamária pós-mastectomia é indispensável para a recuperação física e emocional da mulher, sendo as técnicas utilizadas nos últimos dez anos consistentes, confiáveis, de baixa morbidade e com ótimos resultados estéticos quando bem indicadas.


Introduction: Breast reconstruction after surgical treatment for breast cancer (one of the main cancers that affect women) has been progressively more recommended, given the benefits of psychological recovery and quality of life, whether using implants and/or autologous tissues. The present work aims to demonstrate the team's experience, and discuss operative techniques and complications concerning data from the world literature, in addition to verifying the applicability of the technique in the team's clinical practice. Method: Retrospective observational study developed at a university hospital in Juiz de Fora based on a review of medical records of patients who underwent mastectomy with breast reconstruction between 2010 and 2020. Results: Of the 860 breasts treated, 84% underwent immediate oncological surgery and 16% were late; the main access to the breast tissue was the Stewart incision, followed by extended inframammary, periareolar, and inverted T incisions; regarding reconstructive techniques, 35% of cases used a latissimus dorsi muscle flap, 25% used a prepectoral prosthesis, 20% used a transverse rectus abdominis myocutaneous flap and 10% used a local muscle flap. The most common complications were surgical site dehiscence, followed by skin necrosis, seroma, surgical site infection, and hematoma, in addition to other less common complications such as chronic pain and prosthesis rupture after mammography. Conclusion: Postmastectomy breast reconstruction is essential for a woman's physical and emotional recovery, with the techniques used in the last ten years being consistent, reliable, with low morbidity, and with excellent aesthetic results when correctly indicated.

ABSTRACT

Resumen Introducción : El endofenotipo de cáncer de mama triple negativo (TNBC) es uno de los menos frecuentes y sin diana terapéutica, por tanto, se plantea estudiar la correlación del punto de control inmunológico PD-L1 con el establecimiento de microambiente tumoral evaluado por la infiltración linfocitaria intratumoral estromal (TILs) y su importancia en la práctica clínica. Métodos : Se realizó un estudio retrospectivo de casos y controles, con 31 casos de carcinoma infiltrante de la mama triple negativo y 57 controles no pareados de endofenotipo Luminal A, Luminal B y HER-2 atendidos en un año. Se evaluaron las variables: tipo y grado his tológico, expresión PD-L1 con el clon 22C3, TILs, invasión linfovascular, tamaño tumoral, compromiso de ganglios linfáticos y metástasis. El análisis estadístico se ejecutó con la prueba de chi cuadrado y prueba de coeficiente de correlación de Spearman. Resultados : Se encontró una correlación negativa estadísticamente significativa entre TILs y PD-L1 (rho - 0.106, p 0.025), indicando que a mayor expresión de PD-L1, es menor la infiltración linfocitaria intratumo ral. En los grupos de TILs B (10-40% TILs) y C (40-90% TILs) donde se presenta marcado infiltrado inflamatorio intratumoral se evidenció mayor número de pacientes negativos para PD-L1 (CPS <10) con 16 y 10 casos res pectivamente. Para los casos TNBC se logró identificar un coeficiente de asociación negativa (rho -0.378) y con significancia estadística (p 0.01). Discusión : Se estableció la asociación de TNBC, TILs y expresión de PDL1, lo cual es importante para la instau ración de terapias diana y el desarrollo de la medicina de precisión.


Abstract Introduction : Triple negative breast cancer endophe notype (TNBC) is one of the least frequent and without therapeutic target; therefore we propose to study the correlation of PD-L1 immune checkpoint with the es tablishment of tumor microenvironment assessed by intratumoral stromal lymphocyte infiltration (TILS) and its importance in clinical practice. Methods : A retrospective case-control study was performed, with 31 cases of triple-negative infiltrat ing breast carcinoma and 57 unmatched controls of Luminal A, Luminal B and HER-2 endophenotype seen in one year. The following variables were evaluated: histologic type and grade, PD-L1 expression with clone 22C3, TILS, lymphovascular invasion, tumor size, lymph node involvement and metastasis. Statistical analysis was performed with the chi-square test and Spearman correlation coefficient test. Results : a statistically significant negative correlation was found between TILS and PD-L1 (rho - 0.106, p 0.025), indicating that the higher the expression of PD-L1, the lower the intratumoral lymphocytic infiltration. In the TILS B (10-40% TILS) and C (40-90% TILS) groups where there was a marked intratumoral inflammatory infiltrate, a greater number of patients were negative for PD-L1 (CPS <10) with 16 and 10 cases, respectively. For TNBC cases a negative association coefficient was identified (rho -0.378) with statistical significance (p 0.01). Discussion : The association between TNBC, TILS and PDL1 expression was established, which is important for the establishment of target therapies and the develop ment of precision medicine.

ABSTRACT

INTRODUCTION: Breast cancer is one of the main causes of death in women. Luminal tumors A and B show good response with hormonal treatments, tumors that overexpress HER-2 can be treated with monoclonal antibodies, whereas triple negative tumors have few treatments available because they present low or absent expression of hormone receptors and HER-2, in addition, they present worse tumor progression. Syndecans are heparan sulfate proteoglycans that have the function of interacting with growth factors, cytokines, and extracellular matrix, thus modulating important processes in tumor progression. OBJECTIVE: Analyze the expression of syndecan-4 in different subtypes of breast tumors. METHODS: Bioinformatics is a useful tool for the study of new biomarkers. In the present study, the TCGA database (514 patients) and Metabric (1,898 patients) were analyzed using the cBioportal software. Gene expression data were analyzed by RNA-Seq and Microarray from biopsies of breast tumors. RESULTS: An alteration in syndecan-4 gene expression was observed among the different subtypes of breast tumors. Patients with a triple-negative tumor had decreased expression for syndecan-4 in both databases. CONCLUSION: Syndecan-4 is a potential biomarker for breast tumor prognosis since decreased expression of syndecan-4 is related to triple-negative breast cancer.


INTRODUÇÃO: O câncer de mama corresponde a uma das principais causas de morte em mulheres. Os tumores luminais A e B apresentam boa resposta com tratamentos hormonais, os tumores que superexpressam HER-2 podem ser tratados com anticorpos monoclonais, já os tumores triplo-negativos apresentam poucos tratamentos disponíveis por apresentarem expressão baixa ou ausente dos receptores hormonais e HER-2, além de pior progressão tumoral. Os sindecans são proteoglicanos de heparam sulfato que tem função de interagir com fatores de crescimento, citocinas e matriz extracelular, modulando assim processos importantes na progressão tumoral. OBJETIVO: Analisar a expressão o sindecam-4 nos diferentes subtipos de tumores de mama. MÉTODOS: A bioinformática vem se mostrando útil para estudo de novos biomarcadores. No presente estudo, foi analisado o banco de dados TCGA (514 pacientes) e Metabric (1898 pacientes) utilizando o software cBioportal. Foram analisados os dados de expressão gênica por RNA-Seq e Microarray. RESULTADOS: Foi verificada alteração de expressão gênica do sindecam-4 entre os diferentes subtipos de tumores de mama. Pacientes com tumor triplo-negativo tiveram a expressão diminuída para sindecam-4 em ambos os bancos de dados. CONCLUSÃO: Foi verificado que sindecam-4 parece ser um potencial biomarcador em tumores de mama, a expressão diminuída de sindecam-4 parece estar relacionada a um pior prognóstico.

ABSTRACT

Introducción: El cáncer de mama masculino es una patología infrecuente que re-presenta menos del 1% de la patología mamaria maligna, con una edad media de diagnóstico de 67 años. Tiene un peor pronóstico que el cáncer de mama femenino debido a su alto origen genético y baja sospecha, desencadenando diagnósticos inadecuados y tardíos, y disminuyendo la supervivencia a mediano y largo plazo.Objetivo: Describir el caso clínico de un paciente masculino con diagnóstico de cáncer de mama, abordando la presentación clínica, los métodos diagnósticos, el tratamiento oncoespecífico, y la evolución clínica y quirúrgica. Presentación del caso: Se presenta un paciente masculino de 52 años, con evi-dencia de lesión exofítica en mama derecha más ganglio axilar ipsilateral, con diag-nóstico confirmado de patología de cáncer de mama estadio clínico cT4bN1Mx. Se plantea un manejo multidisciplinario: quimioterapia neoadyuvante y mastecto-mía radical derecha. Finalmente recibe tratamiento oncoespecífico y radioterapia con evolución favorable.Discusión: El cáncer de mama masculino tiene una baja incidencia respecto a la mujer, por lo que su sospecha diagnóstica se ve limitada. En etapas iniciales el diagnóstico es inespecífico debido a las pocas manifestaciones clínicas, pero deberá respaldarse en métodos imagenológicos, análisis anatomopatológico e in-munohistoquímico para guiar el tratamiento oncoespecífico.Conclusión: El cáncer de mama masculino posee una sospecha diagnóstica limi-tada que requiere un manejo multidisciplinario específico. La correcta estadifica-ción de la patología depende del seguimiento clínico y un análisis inmunohistoquí-mico oportuno, para un tratamiento adecuado con mejores resultados clínicos y altas tasas de supervivencia.


Introduction: Male breast cancer is an infrequent pathology; it represents less than 1% of malignant breast pathology, with an average age of diagnosis of 67 years. It has a worse prognosis than female breast cancer, due to its high genetic origin and low suspicion, which leads to inadequate and late diagnosis, becoming evident in advanced stages, decreasing survival in the medium and long term.Objective: To describe the clinical case of a patient diagnosed with breast cancer, addressing the clinical presentation, diagnostic methods, oncospecific treatment, as well as the corresponding clinical and surgical evolution.Case presentation: We present a 52-year-old male patient, with evidence of exophytic lesion in right breast plus ipsilateral axillary node, with diagnosis confir-med by pathology report of breast cancer, clinical stage: cT4bN1Mx. A multidisci-plinary management is proposed, initially the patient receives neoadjuvant chemo-therapy, then undergoes a surgical procedure: radical right mastectomy. Finally, she receives oncospecific treatment in the specialties of clinical oncology and radiothe-rapy, with favorable evolution.Discussion: Male breast cancer has a low incidence compared to women, so its diagnostic suspicion is limited. In initial stages the diagnosis is unspecific due to the few clinical manifestations, but should be supported by imaging methods and confirmatory methods, an anatomopathological and immunohistochemical analy-sis, to guide oncospecific treatment. Conclusions: Male breast cancer, is an infrequent pathology with limited diagnos-tic suspicion, which requires specific multidisciplinary management. It is important to have a continuous medical follow-up of the patient, to achieve at the time of diagnosis a correct clinical and immunohistochemical staging, which allows to fo-cus on the appropriate management and treatment, with better clinical outcomes and better survival rates.

ABSTRACT

El cáncer de mama en coraza constituye una de las formas clínicas de presentación de las metástasis cutáneas del cáncer mamario. Es de aparición poco frecuente, sobre todo, en el sexo masculino. Se presenta el caso de un paciente de sexo masculino, de 74 años de edad, de color de piel negra, con antecedente de diabetes e hipertensión arterial que acudió a consulta de mastología provincial por presentar desde hacía algunos meses dolor discreto y unas lesiones pruriginosas en la mama derecha. Además de otros exámenes se le realizó biopsia escisional de pequeño fragmento de la lesión con estudio por parafina que informó metástasis cutánea de un carcinoma mamario en coraza según su forma de presentación clínica. Se muestra el caso porque no se localizó ninguna publicación en la provincia Cienfuegos ni en el país de un caso en el sexo masculino, por lo cual se considera de interés para el personal médico la publicación de este reporte.


Shell breast cancer is one of the clinical forms of presentation of cutaneous metastases of breast cancer. It is rare, especially in males. The case of a 74-year-old male patient with black skin color, with a history of diabetes and high blood pressure, who attended a provincial mastology consultation for a few months of mild pain and pruritic lesions on his neck, is presented the right breast. In addition to other examinations, an excisional biopsy of a small fragment of the lesion was performed with a paraffin study, which reported cutaneous metastasis of a shell breast carcinoma according to its clinical presentation. The case is shown because no publication was found in the province of Cienfuegos or in the country of a male case, which is why the publication of this report is considered of interest to medical personnel.

ABSTRACT

Introdução: A lipoenxertia é um enxerto autólogo de células do tecido celular subcutâneo, que pode ser utilizada como técnica complementar na reconstrução mamária. Diante disso, a criopreservação de células-tronco mesenquimais provenientes de tecido adiposo (CTDAs) poderia ser uma maneira de realizar a coleta em um tempo cirúrgico e após realizar a lipoenxertia de forma fracionada. O dimetilsulfóxido (DMSO) é um criopreservante utilizado em pesquisas com células, porém é potencialmente tóxico, o que impossibilitaria a utilização de CTDAs criopreservadas na prática clínica. Novos criopreservantes celulares, sem toxicidade, vêm sendo descritos na literatura científica experimental, como as substâncias L-prolina e trealose. Com isso, esse trabalho teve como objetivo avaliar a viabilidade de CTDAs criopreservadas com a combinação de L-prolina e trealose, em um período de até 90 dias. Método: Estudo experimental, no qual foram obtidas amostras de lipoaspirado provenientes de 9 pacientes. A fração celular foi processada e congelada com L-prolina (1,5M) + trealose (0,2M), ou com DMSO + soro fetal bovino (SFB), como controle. Após 30 e 90 dias, as amostras foram descongeladas e a viabilidade celular foi avaliada pela técnica de MTT. Resultados: A análise das CTDAs, após 1 e 3 meses de congelamento, indicou que as amostras tratadas com L-prolina + trealose apresentaram viabilidade semelhante àquelas preservadas com DMSO e SFB (p=0,444). Conclusão: A associação de L-prolina e trealose manteve CTDA viáveis por 30 e 90 dias de congelamento, podendo ser uma alternativa como criopreservante celular sem toxicidade e viabilizando o uso de lipoenxertia seriada.


Introduction: Fat grafting is an autologous graft of cells from subcutaneous tissue, which can be used as a complementary technique in breast reconstruction. Given this, the cryopreservation of adipose tissue-derived mesenchymal stem cells (ADMSCs) could be a way to collect them in one surgical procedure and after performing fractional fat grafting. Dimethyl sulfoxide (DMSO) is a cryopreservative used in cell research, but it is potentially toxic, which would make it impossible to use cryopreserved ADMSCs in clinical practice. New cellular cryopreservatives, without toxicity, have been described in the experimental scientific literature, such as the substances L-proline and trehalose. Therefore, this work aimed to evaluate the viability of ADMSCs cryopreserved with the combination of L-proline and trehalose over up to 90 days. Method: Experimental study in which lipoaspirate samples were obtained from 9 patients. The cellular fraction was processed and frozen with L-proline (1.5M) + trehalose (0.2M) or with DMSO + fetal bovine serum (FBS) as control. After 30 and 90 days, the samples were thawed, and cell viability was assessed using the MTT technique. Results: The analysis of ADMSCs, after 1 and 3 months of freezing, indicated that samples treated with L-proline + trehalose showed similar viability to those preserved with DMSO and SFB (p=0.444). Conclusion: The association of L-proline and trehalose kept ADMSC viable for 30 and 90 days of freezing, and could be an alternative as a cellular cryopreservative without toxicity and enabling the use of serial fat grafting.

ABSTRACT

INTRODUCTION: We aimed to develop a decision aid to support shared-decision making between physicians and women with average breast cancer risk when deciding whether to participate in breast cancer screening. METHODS: We included women at average risk of breast cancer and physicians involved in supporting the decision of breast cancer screening from an Academic Hospital in Buenos Aires, Argentina. We followed the International Patient Decision Aid Standards to develop our decision aid. Guided by a steering group and a multidisciplinary consultancy group including a patient advocate, we reviewed the evidence about breast cancer screening and previous decision aids, explored the patients' information needs on this topic from the patients' and physicians' perspective using semi-structured interviews, and we alpha-tested the prototype to determine its usability, comprehensibility and applicability. RESULTS: We developed the first prototype of a web-based decision aid to use during the clinical encounter with women aged 40 to 69 with average breast cancer risk. After a meeting with our consultancy group, we developed a second prototype that underwent alpha-testing. Physicians and patients agreed that the tool was clear, useful and applicable during a clinical encounter. We refined our final prototype according to their feedback. CONCLUSION: We developed the first decision aid in our region and language on this topic, developed with end-users' input and informed by the best available evidence. We expect this decision aid to help women and physicians make shared decisions during the clinical encounter when talking about breast cancer screening.

ABSTRACT

Introducción: el cáncer de mama es el tumor maligno más frecuente y la primera causa de muerte por cáncer en mujeres en Uruguay y en el mundo. La evidencia epidemiológica sugiere que el cáncer de mama en diferentes grupos de edades se comportaría como patologías distintas. El objetivo de este trabajo es caracterizar el cáncer de mama en Uruguay para diferentes estratos de edades. Material y método: se analizaron las tendencias temporales de la incidencia de cáncer de mama en mujeres en Uruguay en el período 2002-2019, y de la mortalidad por esta causa en 1990-2020. Para el quinquenio 2015-2019, se analiza además la distribución de estadios al diagnóstico y de perfiles biológicos (luminales, triple negativos y HER2 positivos). Se analizan tres segmentos de edades: mujeres de 20 a 44 años, de 45 a 69 y de 70 y más años. Resultados: las tasas de incidencia para el conjunto de edades se presentaron estables en el período 2002-2019, mientras que la mortalidad presenta una tendencia decreciente en el período 1990-2020. En las mujeres menores de 45 años se encuentra un aumento en la incidencia, con mortalidad que decrece hasta el 2010, seguido de una estabilización de las tasas; en las mujeres de 45 a 69 años la incidencia se mantiene estable y la mortalidad decrece; en las mayores de 70 años, la incidencia decrece mientras la mortalidad se mantiene estable. Más del 70% de los casos se diagnostican en estadios I y II. Los tumores luminales (receptores hormonales positivos, HER2 negativos) son el subtipo más frecuente para todos los grupos, la proporción de tumores con estas características aumenta con la edad, mientras decrece la proporción de HER2 positivo y triple negativo. Conclusión: en las mujeres uruguayas el cáncer de mama presenta características diferenciales para las tres franjas de edades analizadas.


Introduction: Breast cancer is the most common malignant tumor and the leading cause of cancer death in women in Uruguay and worldwide. Epidemiological evidence suggests that breast cancer in different age groups behaves as distinct pathologies. The objective of this work is to characterize breast cancer in Uruguay for different age groups. Method: Temporal trends in the incidence of breast cancer in women in Uruguay are analyzed for the period 2002-2019, along with mortality trends for this cause from 1990 to 2020. For the five-year period 2015-2019, the distribution of stages at diagnosis and biological profiles (Luminal, Triple-negative, and Her2 positive) is also analyzed. Three age segments are analyzed: women aged 20 to 44 years, 45 to 69 years, and 70 years and older. Results: The incidence rates for all age groups remained stable during the period 2002-2019, while mortality showed a decreasing trend in the period 1990-2020. In women under 45, there is an increase in incidence, with mortality decreasing until 2010, followed by a stabilization of rates; in women aged 45 to 69, incidence remains stable and mortality decreases; in those over 70, incidence decreases while mortality remains stable. More than 70% of cases are diagnosed at stages I and II. Luminal tumors (hormone receptor positive, Her2 negative) are the most frequent subtype for all age groups. The proportion of tumors with these characteristics increases with age, while the proportion of Her2 positive and triple-negative tumors decreases. Conclusions: In Uruguayan women, breast cancer presents differential characteristics for the three age groups analyzed.


Introdução: O câncer de mama é o tumor maligno mais comum e a principal causa de morte por câncer em mulheres no Uruguai e no mundo. Evidências epidemiológicas sugerem que o câncer de mama se comportaria como patologias distintas em diferentes faixas etárias. O objetivo deste trabalho é caracterizar o câncer de mama no Uruguai para diferentes faixas etárias. Materiais e Métodos: São analisadas as tendências temporais da incidência de câncer de mama em mulheres no Uruguai no período 2002-2019 e a mortalidade por esta causa no período 1990-2020. Para o quinquénio 2015-2019 são também analisadas a distribuição dos estádios ao diagnóstico e os perfis biológicos (Luminal, Triplo negativo e Her2 positivo). São analisados três segmentos etários: mulheres dos 20 aos 44 anos, dos 45 aos 69 anos e dos 70 anos ou mais. Resultados: As taxas de incidência para todas as idades permaneceram estáveis no período 2002-2019 enquanto a mortalidade apresentou tendência decrescente no período 1990-2020. Nas mulheres com menos de 45 anos verifica-se um aumento da incidência, com uma redução da mortalidade até 2010, seguida de uma estabilização das taxas; nas mulheres de 45 a 69 anos, a incidência permanece estável e a mortalidade diminui; nas pessoas com mais de 70 anos, a incidência diminui enquanto a mortalidade permanece estável. Mais de 70% dos casos são diagnosticados nos estágios I e II. Os tumores luminais (receptor hormonal positivo, Her2 negativo) são o subtipo mais comum para todos os grupos sem do que a proporção de tumores com essas características aumenta com a idade, enquanto a proporção de (Her2 positivo e triplo negativo) diminui. Conclusão: Nas mulheres uruguaias, o câncer de mama apresenta características diferenciadas para as três faixas etárias analisadas.

ABSTRACT

Las manifestaciones cutáneas de los tumores malignos comprenden un grupo de dermatosis que pueden ser marcadores de la presencia de neoplasias ocultas y permiten su diagnóstico oportuno. El objetivo de este informe es presentar las características clínicas de una acantosis nigricans asociada a carcinoma de mamario. Para ello, se describe el caso clínico de una paciente de 50 años, color de piel negro, asistida en la consulta de Dermatología del Policlínico Universitario Raúl Sánchez, por tener una placa única eritematosa localizada en la mama izquierda, acompañada de dolor, aumento de la temperatura local y máculas hipercrómicas en las axilas; así como adenopatías axilares múltiples. Los exámenes complementarios mostraron la presencia de acantosis nigricans maligna asociada a un carcinoma inflamatorio de la mama izquierda. Fue intervenida quirúrgicamente, con la consiguiente desaparición de las lesiones cutáneas, pero con un pronóstico reservado. La mayoría de los síndromes paraneoplásicos son inespecíficos; existe una necesidad urgente de sospechar una correlación entre los cambios cutáneos y la posibilidad de una neoplasia interna, por lo que es de suma importancia derivar a estos pacientes para su identificación y el diagnóstico precoz de la enfermedad de base. Esto mejoraría el pronóstico y atenuaría en gran medida las consecuencias.


The skin manifestations of malignant tumors include a group of dermatoses that can be the sign of the occult neoplasms presence and allow their timely diagnosis. The objective of this report is to present the acanthosis nigricans' clinical characteristics associated with breast carcinoma. The clinical case of a 50-years-old black-skinned patient is described, assisted in the Dermatology consultation of the Raúl Sánchez University Polyclinic, for having a single erythematous plaque located in the left breast, accompanied by pain, increased local temperature and hyperchromic macules in the armpits; as well as multiple axillary lymphadenopathy. Complementary examinations showed the presence of malignant acanthosis nigricans associated with an inflammatory carcinoma of the left breast. She underwent surgery, with the consequent disappearance of the skin lesions, but with a reserved prognosis. Most paraneoplastic syndromes are nonspecific; there is an urgent need to suspect a correlation between skin changes and the possibility of an internal neoplasia, so it is of utmost importance to refer these patients for identification and early diagnosis of the underlying disease. This would improve the prognosis and greatly mitigate the consequences.

ABSTRACT

Breast cancer is the malignant tumor with the highest incidence among women in China, and axillary lymph node metastasis is one of the main metastatic pathways of breast cancer. Early detection and accurate assessment of axillary lymph node metastasis has great significance in guiding treatment and judging prognosis. Currently, imaging techniques are widely used in the diagnosis of breast diseases. Ultrasound, as a commonly used clinical imaging method, has become the preferred method for breast cancer lymph node assessment because of its low price, simple operation and multiple testing. This article review the current status of research on the commonly used ultrasound assessment of axillary lymph node metastasis in breast cancer to provide reference for clinical diagnosis and treatment.

ABSTRACT

At present, breast cancer ranks first in the incidence of female malignant tumors, and the age of onset tends to be younger. With the development of comprehensive treatment, most patients can survive for a long time or even be cured clinically. How to improve the quality of life to achieve multiple physical, figure and psychological rehabilitation are the focus of clinical research. Traditional surgical methods have many shortcomings, such as large trauma, slow recovery, many complications, poor physical recovery, and great mental blow to patients, it has been unable to meet the overall medical demands. With the promotion of endoscopic technology in clinical application, endoscopic surgery is increasingly widely used in the surgical treatment of breast cancer, and the technical means are more mature. Its advantages such as concealed incision, small incision, low trauma, good cosmetic effect, and fewer complications can make up for the shortcomings of traditional surgical methods, meet the clinical needs of patients, and have huge advantages in the surgical treatment of breast cancer, it is worth for breast surgeons to learn and further promote. This article reviews the application status and prospect of endoscopic technology in surgical treatment of breast cancer.

ABSTRACT

In recent years, studies have found that breast microbiota differs between breast cancer tissue and normal breast tissue. Breast microbiota is closely related to the occurrence and development of breast cancer, and its mechanism includes affecting estrogen levels, lipid metabolism, immune regulation, and inflammatory response. Adjusting diet, rational use of antibiotics and oral probiotics can regulate breast microbiota, which is a new direction for the prevention and treatment of breast cancer.

ABSTRACT

Objective:To analyze the preoperative and postoperative serum cholinesterase (CHE) levels in patients with stage ⅠA-ⅢA breast cancer who underwent surgical treatment, and to explore the roles of them and peripheral blood inflammatory markers in the prognostic prediction of stage ⅠA-ⅢA breast cancer.Methods:The relevant blood indicators of 152 patients with stage ⅠA-ⅢA breast cancer who underwent surgery and postoperative adjuvant therapy from January 2012 to December 2017 at Affiliated Huai'an Hospital of Xuzhou Medical University were retrospectively studied. The optimal cut-off values of serum CHE levels and peripheral blood inflammatory markers [systemic immune-inflammation index (SII) and systemic inflammatory response index (SIRI) ] were calculated using X-tile 3.6.1 software. Patients were categorized into low and high value groups based on the optimal cutoff values. Kaplan-Meier curves and Cox regression analysis were used to assess the correlation between CHE and peripheral blood inflammation indexes and disease-free survival (DFS). Spearman correlation coefficient and Wilcoxon test were used to assess the correlation and changes of CHE and inflammation indexes before and after treatment. In addition to this, a nomogram prediction model was conscturcted based on independent prognostic factors by R software, which was validated by Bootstrap method.Results:The CHE levels of patients before and after treatment was 8 645.0 (7 251.3, 10 229.3) and 9 309.0 (7 801.0, 10 835.3) U/L, respectively, with a statistically significant difference ( Z=2.73, P=0.006) .The optimal cut-off values for postoperative CHE (Post-CHE), postoperative SII (Post-SII), and postoperative SIRI (Post-SIRI) associated with patients' DFS, being 7 773 U/L, 741, and 0.9, respectively. Univariate analysis showed that tumor size (≤2 cm vs.>2 cm and ≤5 cm: HR=2.55, 95% CI: 1.30-4.99, P=0.006; ≤2 cm vs. >5 cm: HR=8.95, 95% CI: 4.15-19.32, P<0.001), number of positive lymph nodes ( HR=3.84, 95% CI: 2.24-6.58, P<0.001), clinical stage (stage Ⅰ vs. stage Ⅱ: HR=1.52, 95% CI: 0.68-3.39, P=0.309, stage Ⅰ vs. stage Ⅲ: HR=8.12, 95% CI: 3.76-17.55, P<0.001), Ki-67 expression ( HR=2.19, 95% CI: 1.24-3.84, P=0.007), whether radiotherapy ( HR=2.05, 95% CI: 1.19-3.53, P=0.010), Post-CHE ( HR=6.81, 95% CI: 3.94-11.76, P<0.001), Pre-neutrophil to lymphocyte ratio (NLR) ( HR=1.11, 95% CI: 1.02-1.21, P=0.014), Post-NLR ( HR=5.23, 95% CI: 2.78-9.85, P<0.001), Pre-platelet to lymphocyte ratio (PLR) ( HR=2.08, 95% CI: 1.01-4.26, P=0.046), Post-PLR ( HR=7.11, 95% CI: 3.78-13.37, P<0.001), Pre-lymphocyte to monocyte ratio (LMR) ( HR=0.37, 95% CI: 0.20-0.66, P<0.001), Post-LMR ( HR=0.23, 95% CI: 0.13-0.41, P<0.001), Pre-SII ( HR=1.81, 95% CI: 1.05-3.12, P=0.033), Post-SII ( HR=6.12, 95% CI: 3.48-10.76, P<0.001), Pre-SIRI ( HR=2.12, 95% CI: 1.24-3.63, P=0.006), and Post-SIRI ( HR=4.93, 95% CI: 2.87-8.48, P<0.001) were associated with DFS in patients with stage ⅠA-ⅢA breast cancer. Multivariate analysis showed that tumor size (≤2 cm vs. >2 cm and ≤5 cm: HR=2.86, 95% CI: 1.41-5.78, P=0.003; ≤2 cm vs. >5 cm: HR=3.72, 95% CI: 1.50-9.26, P=0.005), number of positive lymph nodes ( HR=4.66, 95% CI: 2.28-9.54, P<0.001), Ki-67 expression ( HR=2.13, 95% CI: 1.15-3.94, P=0.016), Post-CHE ( HR=0.18, 95% CI: 0.10-0.33, P<0.001), Post-SII ( HR=2.71, 95% CI: 1.39-5.29, P=0.004), and Post-SIRI ( HR=3.77, 95% CI: 1.93-7.36, P<0.001) were independent influencing factors for DFS in patients with stage ⅠA-ⅢA breast cancer. Kaplan-Meier survival curve analysis showed that the median DFS of patients in the Ki-67<30% group was not reached, and the median DFS of patients in the Ki-67≥30% group was 89.0 months, and the 3- and 5-year DFS rates were 84.9% vs. 75.9% and 80.8% vs. 64.3%, respectively, with a statistically significant difference ( χ2=7.65, P=0.006) ; the median DFS of patients in the tumor size≤2 cm group was not reached, the median DFS of the 2 cm<tumor size≤5 cm group was 93.5 months, and the median DFS of the tumor size>5 cm group was 26.3 months, and the 3- and 5-year DFS rates were 95.5% vs. 74.6% vs. 42.1%, 86.3% vs. 68.6% vs. 25.3%, with a statistically significant difference ( χ2=40.46, P<0.001) ; the median DFS of patients in the group with the number of positive lymph nodes<4 was not reached, and the median DFS of the group with the number of positive lymph nodes≥4 was 30.7 months, and the 3- and 5-year DFS rates were 87.9% vs. 46.4% and 81.4% vs. 28.6%, respectively, with a statistically significant difference ( χ2= 47.34, P<0.001) ; the median DFS of patients in the Post-CHE<7 773 U/L group was 47.3 months, and the median DFS of patients in the Post-CHE≥7 773 U/L group was not reached, and the 3- and 5-year DFS rates were 52.8 % vs. 88.6% and 27.8% vs. 81.2%, respectively, with a statistically significant difference ( χ2=62.17, P<0.001) ; the median DFS was not achieved in patients in the Post-SII<741 group, and the median DFS was 30.5 months in the Post-SII≥741 group, with 3- and 5-year DFS rates of 88.1% vs. 38.5% and 80.1% vs. 30.8%, respectively, with a statistically significant difference ( χ2=50.78, P<0.001) ; the median DFS of patients in Post-SIRI<0.9 group was not reached, the median DFS of Post-SIRI≥0.9 group was 33.3 months, and the 3- and 5-year DFS rates were 93.5% vs. 46.7% and 84.9% vs. 39.9%, respectively, with a statistically significant difference ( χ2=40.67, P<0.001). Spearman correlation analysis revealed that Post-CHE was not correlated with Post-SII ( r=-0.111, P=0.175), and Post-CHE was negatively correlated with Post-SIRI ( r=-0.228, P=0.005). Post-treatment CHE was elevated compared to preoperative and the median DFS was not reached in patients with elevated CHE group and 61.8 months in patients with reduced CHE group after treatment, with a statistically significant difference ( χ2=25.67, P<0.001). The nomogram based on independent prognostic factors had good predictive performance, with a C-index of 0.893. Conclusion:The serum CHE level exhibited a significant increase following treatment. Postoperative serum CHE combined with SII and SIRI can effectively predict DFS in patients with stage ⅠA-ⅢA breast cancer, and the prognosis of patients with elevated CHE after treatment is better. The nomogram constructed based on independent prognostic factors has good predictive performance for DFS in breast cancer patients.

ABSTRACT

Objective:To explore the potential mechanism of Huayu Pills in the treatment of TNBC (triple-negative breast cancer) using network pharmacology.Methods:TCMSP (Traditional Chinese Medicine Systems Pharmacology), PubChem, STITCH and SwissTargetPrediction databases were used to analyze the potential targets of Huayu Pills. TNBC disease targets were screened based on the TCGA (The Cancer Genome Atlas) database. The drug-disease mapping target was constructed by PPI network, key target screening and module analysis, and the DAVID database was used for GO function annotation and KEGG signal pathway enrichment analysis. SD rats were orally administered 3.94 g/kg of Huayu Pills decoction for 4 days to prepare medicated serum. HUVEC cells were randomly divided into a control group and an experimental group using a random number table method. The experimental group received intervention with Huayu Pills containing serum for 24 hours, inoculated in matrigel's solidified 48 well plate and HUVEC angiogenesis was observed 3 hours later.Results:130 possible targets of Huayu Pills in the treatment of TNBC were obtained. VEGFA is the core target. The cascade of angiogenesis, hypoxia, and blood coagulation may be the main functions and key signals of Huayu Pills in the treatment of TNBC. In vitro studies have shown that serum containing Huayu Pills can promote the normalization of tumor blood vessels in HUVEC cells.Conclusion:Huayu Pills may promote tumor vascular normalization (angiogenesis, hypoxia, coagulation cascade reactions) through VEGF targets, and can assist immune checkpoint inhibitors in the treatment of TNBC.

ABSTRACT

Objective To investigate the value of breast MRI-abbreviated protocol(BMRI-AP)compared with full field digital mammography(FFDM)and breast MRI-full diagnostic protocol(BMRI-FDP)in the diagnosis of early breast cancer with non-calcified.Methods A total of 95 cases patients with early breast cancer with non-calcified(the longest diameter of the lesion≤2 cm,regardless of the size of the carcinoma in situ)were retrospectively included.Clinical,pathological and imaging data of all patients were collected.All patients underwent FFDM and MRI scanning,and three examination regimens,including FFDM,BMRI-AP,BMRI-FDP,were further obtained.Classification was performed according to the breast imaging reporting and data system(BI-RADS)classification standard(fifth edition)developed by American College of Radiology(ACR),and pathological results were taken as the standard.The diagnostic efficacy for early breast cancer with non-calcified were compared among the different three imaging methods.Results The diagnostic accuracy of FFDM,BMRI-AP and BMRI-FDP for early breast cancer with non-calcified was 76.84%,93.68%and 95.79%,respectively,with statistically significant difference among three groups(χ2=20.558,P<0.001).The median(quartile distance)of BMRI-AP and BMRI-FDP scanning time were 478(5)s and 926(13)s,respectively,with statistically significant difference between the two groups(Z=-11.912,P<0.001).Conclusion The diagnostic accuracy of BMRI-AP is significantly better than that of FFDM and similar to that of BMRI-FDP for early breast cancer with non-calcified.In addition,BMRI-AP can significantly shorten the scanning time without reducing the diagnostic accuracy,which is expected to become a new breast cancer screening method.
