Estudio comparativo de supervivencias entre la actual y la antigua clasificación del carcinoma broncogénico / Comparative survival study between the old and new bronchogenic carcinoma classification

La nueva clasificación del carcinoma broncogénico ha sido realizada por la Association for the Study of Lung Cancer (IASLC) y publicada por Frank C. Detterbeck et al en la revista Chest (2009). En el Servicio de Cirugía Torácica del Hospital Universitario de Gerona se ha re-estadificado la serie quirúrgica de pacientes intervenidos de carcinoma broncogénico con intención curativa con el objetivo de comparar la supervivencia (supervivencia por T, supervivencia por M y supervivencia por estadios patológicos) entre la antigua y la actual clasificación y además objetivar si estos cambios de supervivencia son estadísticamente significativos. Otro de los objetivos del trabajo es el de establecer la concordancia entre la supervivencia actual de nuestra serie quirúrgica y la publicada por la IASLC. Pacientes y métodos Se introdujeron en una base de datos 855 pacientes intervenidos con intención curativa de carcinoma broncogénico. Fueron estadificados radiológica, clínica y patológicamente según la antigua y la nueva estadificación. Se calculó la supervivencia según la T, la N, la M y los estadios patológicos. Se realizó un estudio estadístico con el programa SPSS, con el que se analizaron los cambios de supervivencia entre ambas clasificaciones. Resultados Se objetivaron cambios de supervivencia no estadísticamente significativos (p=0,58) con la nueva estadificación en el estadio IIA y cambios de supervivencia estadísticamente significativos (p=0,001) en el estadio IIIB. Discusión El estudio confirma que la actual clasificación TNM es útil ya que muestra cambios de supervivencia en 2 estadios patológicos (uno de ellos estadísticamente significativo). Actualmente, los datos de supervivencia de nuestra serie se adecuan mejor a los que aporta la IASLC(AU)

Introduction: A new classification of bronchogenic carcinoma has been made by the International Association for the Study of Lung Cancer (IASLC) and published by Frank C.Detterbeck et al in the journal Chest (2009). The Thoracic Surgery Department of the Gerona(Spain) University Hospital has re-staged a series of patients with bronchogenic carcinoma who had attempted curative surgery, with the aim of comparing the survival (survival for T, survival for M, and survival by disease staging) between the old and new classification, and also to determine whether these changes in survival are statistically significant. Anotherone of the objectives of the study is to see whether there is agreement between the currentsurvival of our surgical series and that published by the IASLC. Patients and methods: Data on 855 patients who had attempted bronchogenic carcinomacurative surgery were entered into a data base. They were radiologically, clinically and histologically staged according to the new and old staging. Survival was calculated according to the T, M, N, and histology stages. A statistical analysis was performed using the SPSS program and the changes in survival between both classifications were analysed. Results: No statistically significant changes were observed in survival (P = .58) with the new classification in stage IIA, but there were statistically significant changes in survival(P = .0001) in stage IIIB. Discussion: The study confirms that the current TNM classification is useful, since it shows changes in survival in 2 histological stages (one of them statistically significant). The survival data of our series now fits better with those provided by the IASLC (AU)

We present 2 cases in which, when faced with suspicion of catamenial hemopneumothorax or pneumothorax, video-assisted thoracoscopy was used for identification, biopsy, and electrocoagulation of the tissue sites where pleural endometriosis was suspected.
