RESUMO

RESUMEN Introducción: el cáncer de mama es una de las enfermedades más frecuente en las féminas de varios países. Objetivo: caracterizar el cáncer de mama invasivo según subtipos moleculares en Pinar del Río, en el periodo 2013-2015. Métodos: estudio observacional descriptivo, de corte transversal, desarrollado en el Hospital Oncológico III Congreso de la provincia Pinar del Río, entre 2013 y 2015. De un universo de 452 pacientes con diagnóstico de cáncer de mama, fue seleccionada intencionalmente una muestra de 198, se cumplieron los criterios de inclusión. El análisis de historias clínicas permitió la obtención de información que dio salida a las variables estudiadas, se recurrió a la estadística descriptiva para el análisis de los resultados. Se respetó la ética médica. Resultados: los tumores se localizaron en la mama izquierda en 67 % de los casos, con predominio de tumores de menos de 2 centímetros en el 51,5 % de estos. En el 25,8 % de los pacientes ocurrió metástasis a cadenas ganglionares, con predominio de invasión numérica del subtipo receptor del factor de crecimiento epidérmico humano (HER2) en 38,1 %, este subtipo molecular fue también el de mayor grado de diferenciación histológica (grado III) con 91,7 % del total. Conclusiones: la adecuada localización, determinación del tamaño tumoral, invasión hacia cadenas ganglionares axilares del cáncer de mama, así como la determinación del grado de diferenciación histológica, apoyado en estudios inmunohistoquímicos, permiten el correcto accionar médico al dirigir la terapéutica a seguir en dependencia de las características mostradas por estos estudios.


ABSTRACT Introduction: the research responds to the need to broaden and diversify the psychological counseling offered to the population of Pinar del Río through television, with emphasis on families that are in situations of immigration. Objective: to design the television program Conversemos (Let's Talk), as a proposal of psychological counseling directed to families in situations of immigration, in order to contribute to family satisfactory functioning. Methods: a cross-sectional study was carried out that combined descriptive and explanatory elements, with the application of historical-logical methods, modeling, structural-systemic, interview, survey and documentary analysis. A diagnosis was developed in the telecenter of Pinar del Río province, Cuba. Results: it was corroborated that the motivation of those involved on the subject of family in situations of immigration was satisfactory, but not the satisfaction with its current treatment, which was low. Knowledge level of the specialists was high, but the level of knowledge of the directors and the audience was limited. The TV-program Let's Talk was designed to offer to Pinar del Río audience a space for counseling that would develop skills and resources to cope successfully with the immigration problem. Conclusion: the psychological counseling offered by Pinar del Río telecenter to the family in situations of immigration was insufficient. There was a high level of motivation towards the subject on the part of the audience and the specialists, who had adequate knowledge on the subject, but limited level of knowledge on the part of the audience and the directors of the telecenter, which determined low levels of satisfaction in all people involved.

RESUMO

El intervencionismo en mama se inició con la localización preoperatoria de lesiones no palpables. En una segunda etapa, el desarrollo de técnicas de biopsias en las tres modalidades (mamografía, ultrasonido y resonancia magnética), reforzaron las indicaciones de localización de lesiones con histología ya confirmada. La técnica de localización en Argentina se basó casi exclusivamente en la inserción de alambres con arpones e inyección de carbón. A partir del año 2001, se ofreció como alternativa a las localizaciones con arpones la inserción de semilla de Iodo-125, considerando las ventajas para la paciente, el cirujano y el sistema hospitalario al desacoplar los turnos de quirófano y servicios de imágenes, otorgando acceso a cualquier cuadrante con incisiones cosméticas. La provisión del isótopo es la clave para instalar y atender la demanda de los usuarios, una vez que han conocido los méritos del procedimiento. En todos los ámbitos y distintos países, se verificó una lenta incorporación a la rutina de localización de lesiones con material radioactivo, primariamente por las regulaciones fundamentales y justificadas para la adquisición del isótopo. En nuestro medio y en una labor conjunta con la Autoridad Regulatoria Nuclear (ARN), logramos finalmente, en el año 2017, el reconocimiento de la práctica. Revisamos la bibliografía, describimos la técnica y la logística para lograr autorización de aquellos centros interesados en aplicar un procedimiento universalmente adoptado por sus ventajas respecto a los métodos tradicionales.


Diagnostic intervention in breast disease started with preoperative localization of non- palpable lesions. Later, with the histological diagnosis obtained through biopsy techniques in mammography, ultrasound and magnetic resonance imaging, the localization of lesions has become a must. Traditionally, in Argentina, the localization technique was exclusively based on the insertion of harpoon-shaped guided wires and carbon suspension. Since 2001, the iodine-125 radioactive seed localization has emerged as a reliable and advantageous alternative for the patient, the surgeon and the hospital system, reducing scheduling conflicts between the breast imaging department and the surgical department, and allowing access to any quadrant with cosmetic incisions. The isotope provision is the key to satisfying the users demand, once they have known the merits of the procedure. The implementation of radioactive material for the localization of lesions has been tardy in all fields and in different countries, mainly due to justified regulations related to the acquisition of the isotope. As a result of joint efforts with the Autoridad Regulatoria Nuclear (Nuclear Regulatory Authority), the practice finally gained its deserved recognition in 2017. We conducted a review of the existing literature and described the technique and the logistics to obtain the approval of the sites that were interested in the deployment of a widely used procedure that has proved to be more advantageous than traditional methods.

RESUMO

ABSTRACT Objective To define a predictive factor for pathologic complete response, compare the oncologic outcomes associated with the degree of pathologic response after neoadjuvant chemotherapy, and to analyze pathologic complete response as a prognostic factor for overall survival and progression-free survival. Methods A retrospective study of patients admitted to Hospital Estadual Mário Covas and Hospital Anchieta from 2008 to 2012, with locally advanced breast cancer. Hormone receptor status, HER2 status, histologic and nuclear grade, age upon diagnosis and histological type of the tumor were analyzed. Pathologic evaluation of the tumor was subdivided into pathologic complete response, defined by the absence of tumor; intermediate response, considered as a favorable stage; and poor response, considering low-responder patients. Data obtained were submitted to statistical analysis. Results The study included 243 patients. There was an association of pathologic complete response with HER-2 negative, histological grade 3, stage III, hormone receptor negative, positive lymph node, older age and more advanced tumors. However, after multivariate analysis the only predictor of pathologic complete response was the presence of negative hormone receptor. By analyzing the prognostic factors, hormone receptor negative was considered as an independent risk factor, and pathologic complete response was considered as an independent protective factor. Conclusion Hormone receptor negative is predictive of pathologic complete response and is an isolated risk factor for lower progression-free survival and overall survival. Pathologic complete response is a protective factor for these same survival analyses.


RESUMO Objetivo Definir um fator preditivo para resposta patológica completa, comparar os resultados oncológicos associados com o grau de resposta patológica, após quimioterapia neoadjuvante, e analisar a resposta patológica completa como fator prognóstico para sobrevivência global e livre de progressão de doença. Métodos Estudo retrospectivo de pacientes admitidas no Hospital Estadual Mário Covas e Hospital Anchieta, no período de 2008 a 2012, com câncer de mama localmente avançado. Foram utilizados status dos receptores hormonais, proteína HER2, grau histológico e nuclear, idade do paciente ao diagnóstico e tipo histológico do tumor. A avaliação patológica do tumor foi subdividida em resposta patológica completa, definida com ausência de tumor; resposta intermediária, considerada como um estádio favorável; e resposta ruim, considerando os pacientes pouco respondedores. As informações obtidas foram submetidas à análise estatística. Resultados Foram incluídas 243 pacientes. Verificou-se associação de resposta patológica completa entre HER-2 negativo, grau histológico 3, estadiamento III, receptor hormonal negativo, linfonodo positivo, maior idade e tumores mais avançados. Porém, após análise multivariada, o único fator preditivo de resposta patológica completa foi presença de receptor hormonal negativo. Ao analisar fatores prognósticos, receptor hormonal negativo permaneceu como variável independente de risco, e resposta patológica completa, como variável independente de proteção. Conclusão O receptor hormonal negativo é fator preditivo isolado de resposta patológica completa e fator de risco para menor sobrevida livre de doença e sobrevida global. Já a resposta patológica completa é fator protetor para estas mesmas análises de sobrevivência.

RESUMO

PURPOSE: To estimate the likelihood of axillary lymph node involvement for patients with early-stage breast cancer, based on a variety of clinical and pathological factors. METHODS: A retrospective analysis was done in hospital databases from 1999 to 2007. Two hundred thirty-nine patients were diagnosed with early-stage breast cancer. Predictive factors, such as patient age, tumor size, lymphovascular invasion, histological grade and immunohistochemical subtype were analyzed to identify variables that may be associated with axillary lymph node metastasis. RESULTS: Patients with tumors that are negative for estrogen receptor, progesterone receptor, and HER2 had approximately a 90% lower chance of developing lymph node metastasis than those with luminal A tumors (e.g., ER+ and/or PR+ and HER2-) - Odds Ratio: 0.11; 95% confidence interval: 0.01-0.88; p=0.01. Furthermore, the risk for lymph node metastasis of luminal A tumors seemed to decrease as patient age increased, and it was directly correlated with tumor size. CONCLUSION: The molecular classification of early-stage breast cancer using immunohistochemistry may help predicting the probability of developing axillary lymph node metastasis. Further studies are needed to optimize predictions for nodal involvement, with the aim of aiding the decision-making process for breast cancer treatment. .


OBJETIVO: Estimar a probabilidade de acometimento linfonodal em pacientes com câncer de mama inicial, baseado em fatores clínicos e patológicos. MÉTODOS: Foi realizada uma análise retrospectiva de 1999 a 2007 dos bancos de dados do hospital. Um total de 239 pacientes foram diagnosticados com câncer de mama em estádio inicial. Fatores preditivos como idade, tamanho do tumor, presença de invasão linfovascular, grau histológico e subtipo imunoistoquímico foram analisados para identificar possíveis variáveis associadas com a presença de metástases axilares. RESULTADOS: Pacientes com tumores negativos para receptor de estrogênio, receptor de progesterona e HER2 tiveram aproximadamente 90% menos chance de terem metástases axilares do que pacientes com tumores luminais A (por exemplo, ER+ e/ou PR+ e HER2-) - Odds Ratio: 0,11; intervalo de confiança de 95%: 0,01-0,88; p=0,013. Além disso, o risco de metástases axilares para tumores luminais A diminuiu com o aumento da idade e se correlacionou diretamente com o tamanho do tumor. CONCLUSÃO: A classificação molecular do câncer de mama em estádio inicial utilizando a imunoistoquímica pode ajudar a predizer a probabilidade de encontrar metástases axilares. Novos estudos são necessários para otimizar essa predição, auxiliando no processo de decisão do tratamento relacionado ao câncer de mama. .
