OBJETIVO: Existe controversia sobre el papel de las diferentes técnicas diagnósticas en la estadificación del mediastino en pacientes con sospecha de cáncer de pulmón. El objetivo del estudio ha sido analizar la rentabilidad diagnóstica y el coste-beneficio de la punción transbronquial aspirativa (PTA) en la estadificación mediastínica del cáncer de pulmón, en pacientes evaluados en un hospital de tercer nivel. PACIENTES Y MÉTODOS: Se ha realizado un estudio observacional retrospectivo, en el que se han analizado los resultados de las PTA practicadas a pacientes con sospecha de cáncer de pulmón y adenopatías mediastínicas patológicas. También se ha evaluado el coste-beneficio de la aplicación sistemática de esta técnica. RESULTADOS: Se evaluó a 194 pacientes (un 85% varones y un 15% mujeres), en 157 de los cuales (81%) se confirmó el diagnóstico de cáncer de pulmón. La muestra citológica que se obtuvo de la PTA fue adecuada en 147 de los 194 casos (76%). Cuando se analizaron las muestras adecuadas, la sensibilidad de la PTA fue del 88%, la especificidad del 100%, el valor predictivo positivo del 100%, el valor predictivo negativo del 64% y el valor global del 90%. En 44 de los 127 casos (34%) con cáncer de pulmón no microcítico localizado se evitó la realización de una mediastinoscopia, lo que representó un ahorro económico estimado de 119.456 ¿. CONCLUSIONES: La PTA es una técnica con una elevada rentabilidad diagnóstica que puede evitar la realización de una mediastinoscopia en un porcentaje significativo de pacientes, con las consiguientes implicaciones terapéuticas y económicas que ello conlleva
OBJECTIVE: The role of different techniques for mediastinal staging in patients with suspected lung cancer is a subject of debate. The aim of this study was to analyze the diagnostic yield and cost-effectiveness of transbronchial needle aspiration in the mediastinal staging of lung cancer in patients being evaluated in a tertiary hospital. PATIENTS AND METHODS: This was a retrospective, observational study of the results of transbronchial needle aspiration in patients with suspected lung cancer and mediastinal lymph node involvement. A cost-effectiveness analysis of the systematic use of this technique was also performed. RESULTS: One-hundred ninety-four patients (85% men, 15% women) were evaluated. The diagnosis of lung cancer was confirmed in 157 (81%). Cytology samples obtained by transbronchial needle aspiration were adequate in 147 (76%) of the 194 cases. When only the adequate samples were included in the analysis, transbronchial needle aspiration showed a sensitivity of 88%, specificity of 100%, positive predictive value of 100%, negative predictive value of 64%, and efficiency of 90%. Mediastinoscopy was avoided in 44 (34%) of the 127 patients with localized non-small cell lung cancer, with an estimated saving of ¿119 456. CONCLUSIONS: Transbronchial needle aspiration has a high diagnostic yield and obviates the need for mediastinoscopy in a significant percentage of cases. This finding is of diagnostic and economic significance
