RESUMO
Background: Breast cancer is a highly heterogeneous disease with large differences in the risk of recurrence. An elevated neutrophil-to-lymphocyte ratio (NLR) is correlated with a poor prognosis in a variety of tumors, and although it is still controversial in breast cancer, there are multiple studies, including meta-analysis, suggesting this. The purpose of this study was to analyze the prognostic value of preoperative NLR in an Argentine population of patients with nonmetastatic breast cancer, not exposed to neoadjuvant treatment. Methods: Retrospective multicenter cohort study that includes patients over 18 years of age from three centers in the city and province of Buenos Aires who have had surgery for early breast cancer between January 1, 1999, and December 31, 2014. Based on the previous literature, a cutoff value of 2.0 was defined. Results: A total of 791 patients were eligible for the analysis. Median age was 55 years (IQR 45-65). Median NLR was 1.92 (IQR 1.50-2.56). The distribution of groups according to the 8th edition of the AJCC was 54.1% for stage I, 35.6% stage II, and 10.4% stage III. Among the different tumor phenotypes, 79.0% were HR+/HER2-, 11.4% were HR+ or-/HER2+, and 9.2% were HR-/HER2-. With a median follow-up of 5.3 years, 112 patients (14.2%) had disease recurrence. Stage III patients had a higher NLR than stage I and stage II patients (p = 0.002). The rest of the clinical and pathological characteristics did not show differences in the groups according to NLR. There were no differences in relapse-free survival according to the NLR (p = 0.37), and it did not change after adjusting for other prognostic variables. Conclusion: We consider it is important to determine the efficacy of prognostic markers that are easily accessible and of simple, systematic application. However, NLR does not appear to be an independent prognostic factor for recurrence in our population. In this sense, we consider it is important to publish negative results in order to avoid publication bias.
RESUMO
Introducción Las pacientes con Carcinoma Ductal in Situ de mama (cdis) tienen mayor riesgo de desarrollar carcinoma invasor. Aquellas con receptores hormonales positivos se beneficiarían con hormonoterapia. El largo período de tratamiento y los efectos adversos asociados al mismo hacen dificultosa la adherencia. Objetivos El objetivo del presente trabajo es analizar la adherencia a la hormonoterapia en pacientes operadas por Carcinoma Ductal in Situ en el Hospital Universitario Austral. Material y método Es un estudio observacional, analítico, de corte transversal. Se incluyeron pacientes con diagnóstico de Carcinoma Ductal in Situ que fueron intervenidas quirúrgicamente en el Hospital Universitario Austral en el período comprendido entre el 24 de julio de 2000 y el 5 de julio de 2017. Los datos fueron recopilados a través de una encuesta. Resultados Se obtuvieron 100 encuestas. La adherencia fue del 82%. La misma no se modificó según edad, conocimiento de riesgos y beneficios del tratamiento, tipo y número de cirugías, radioterapia y número de consultas. Las reacciones adversas a la medicación fueron la causa más frecuente de abandono al tratamiento. Conclusiones El tratamiento multidisciplinario podría asegurar un óptimo nivel de adherencia
Introduction Patients with Ductal Carcinoma in Situ of the breast (dcis) have a higher risk of developing invasive carcinoma. Those with hormone receptor-positive would benefit from hormonal therapy. The long period of treatment and the associated adverse events make adherence difficult. Objectives The aim of this study is to analyze the adherence of hormonal therapy in operated patients with Ductal Carcinoma in Situ at Hospital Universitario Austral. Materials and method It is an observational, analytical and cross-sectional study. Patients diagnosed with Ductal Carcinoma in Situ who underwent surgery at Hospital Universitario Austral in the period between 07/24/2000 and 07/05/2017 were included. The data was collected through a survey. Results 100 surveys were obtained. The adherence was 82%. It was not modified according to age, knowledge of risks and benefits of the treatment, type and number of surgeries, radiotherapy and number of consultations. Adverse events were the most frequent cause of discontinue of treatment. Conclusions Multidisciplinary treatment could ensure an optimal level of adherence

Introducción El cáncer de mama (cm) es la principal causa de muerte por enfermedad oncológica en mujeres. Con el aumento de su incidencia y de las tasas de sobrevida, resulta importante evaluar los efectos de la enfermedad en la calidad de vida (cv) de las pacientes. Objetivos Medir el impacto del diagnóstico y tratamientos del cm en la cv de las pacientes e identificar factores de riesgo (fr) para la afectación de las distintas dimensiones de la cv, a fin de brindar mejor contención e implementar medidas específicas. Material y método Es un estudio observacional, analítico, transversal. Se incluyeron pacientes con diagnóstico y tratamientos por cm en tiempos y lugares variables, tratadas actualmente en el Centro Mamario del Hospital Universitario Austral. La información se obtuvo a través de encuestas anónimas, que incluían dos cuestionarios que evaluaban cv en cáncer (eortc qlq-c30) y en cm específicamente (eortc qlq-br23) y un cuestionario propio. Resultados Se obtuvieron 171 encuestas. El promedio de cv fue bueno en todos los grupos. La escala de funcionamiento emocional fue la más afectada. Los síntomas más frecuentes fueron: fatiga e insomnio. El funcionamiento sexual y la preocupación por el futuro fueron las áreas de mayor afectación en el cuestionario específico de cm. Los síntomas específicos más reportados fueron las molestias por la pérdida del cabello. Logramos identificar al menos 10 fr con diferencias estadísticamente significativas. Conclusiones Resulta fundamental el conocimiento de la población tratada para medir el impacto de la enfermedad y de sus tratamientos y para reconocer los grupos más vulnerables. Esto permite no solo implementar medidas para mejorar la cv de las pacientes sino también mejorar la relación médicopaciente
Introduction Breast cancer (bc) is the main cause of death due to malignancy in women. With its rising incidence and prolonged survival rates, it is important to assess its effect on quality of life (qol) on women. Objectives To measure the impact of bc diagnosis and treatments on patients' qol and to identify wich risk factors (rf) play a role on qol, in orther to better understand, improve and develop patient centered care strategies. Materials and method This is a cross-sectional observational study of women with a diagnosis of bc who received treatment at different institutions, with different followup times, that are currently treated at the Breast Center of the Hospital Universitario Austral. Patients were evaluated via anonymous surveys, which included two questionnaires that evaluated qol in cancer (eortc qlq-c30) and in bc specifically (eortc qlq-br23), and a personalized questionnaire of our own. Results 171 surveys were obtained. The average qol was scored good among all groups. The emotional functioning scale was the most affected. The most frequent symptoms experienced were fatigue and insomnia. Sexual functioning and future perspectives were the most affected areas in the specific bc questionnaire. The specific symptom most commonly reported was upset by hair loss. At least 10 rf with statistically significant differences were identified. Conclusions Knowledge of the treated population is essential to assess the impact of the disease and its treatments, and to know the most vulnerable groups. This allows, not only the implementation of actions to improve patients' qol, but also to improve the doctor-patient relationship
