Supervivencia de pacientes con fibrosis pulmonar idiopática diagnosticados por biopsia quirúrgica de pulmón: experiencia del Instituto Nacional del Tórax / Survival of patients with biopsy-proven idiopathic pulmonary fibrosis: Chilean National Thorax Institute experience
Data from 142 patients with a mean age of 58 years (42% men), were analyzed. Mean initial lung function showed a forced vital capacity (FVC) of 73%, carbon monoxide diffusing capacity (DLCO) of 57% and a distance covered in 6-minute walk (6MWT) of 95% of expected normal values. The median survival was 80 months. Predictors of survival were a DLCO of less than 40% and an oxygen saturation at the end of the 6MWT of less than 89%.
