Introducción: La información sobre la asociación del cáncer de pulmón (CP) y combinación de fibrosis pulmonar y enfisema (CFPE) es limitada y procedente casi exclusivamente de series asiáticas. El objetivo principal del estudio fue valorar el impacto del CP en la supervivencia en la CFPE y en pacientes diagnosticados de fibrosis pulmonar idiopática (FPI). Métodos: Se realizó un estudio retrospectivo con los datos de pacientes con CFPE y FPI diagnosticados en nuestro centro en un periodo de 5 años. Resultados: Se incluyó a 66 pacientes, 29 en el grupo de CFPE y 37 pacientes con FPI. Nueve tenían un diagnóstico de CP (6 con CFPE y 3 con FPI); 6 pacientes (67%) recibieron tratamiento paliativo a pesar de que 3 de ellos presentaban estadios I y II. No hubo diferencias significativas en la mortalidad global de los 2 grupos; sin embargo, en los pacientes con CP la supervivencia fue significativamente menor con respecto a los que no tenían CP (p = 0,044). Las causas más frecuentes de muerte fue la insuficiencia respiratoria secundaria a la exacerbación de la fibrosis pulmonar (44%). En el análisis multivariante, la odds ratio de morir en los pacientes con CP respecto a los pacientes sin CP fue de 6,20 (p = 0,037, intervalo de confianza [IC] del 95%: 1,11 a 34,48). Conclusión: El CP empeora la supervivencia de estas 2 entidades. El manejo diagnóstico y terapéutico del CP se ve dificultado por el mayor riesgo de complicaciones posteriores al tratamiento elegido, incluso tras el tratamiento paliativo (AU)
Introduction: Information on the association of lung cancer (LC) and combined pulmonary fibrosis and emphysema (CPFE) is limited and derived almost exclusively from series in Asian populations. The main objective of the study was to assess the impact of LC on survival in CPFE patients and in patients with idiopathic pulmonary fibrosis (IPF). Methods: A retrospective study was performed with data from patients with CFPE and IPF diagnosed in our hospital over a period of 5 years. Results: Sixty-six patients were included, 29 with CPFE and 37 with IPF. Nine had a diagnosis of LC (6 with CPFE and 3 with IPF). Six patients (67%) received palliative treatment even though 3 of them were diagnosed atstage I-II. Overall mortality did not differ significantly between groups; however, in patients with LC, survival was significantly lower compared to those without LC (P =.044). The most frequent cause of death was respiratory failure secondary to pulmonary fibrosis exacerbation (44%). In a multivariate analysis, the odds ratio of death among patients with LC compared to patients without LC was 6.20 (P =.037, 95% confidence interval: 1.11 to 34.48). Conclusions: Lung cancer reduces survival in both entities. The diagnostic and therapeutic management of LC is hampered by the increased risk of complications after any treatment modality, even after palliative treatment (AU)
