Utility of the DECAF score for predicting survival of patients with COPD: a meta-analysis of diagnostic accuracy studies.

Objective: The DECAF (Dyspnea, Eosinopenia, Consolidation, Acidemia, Atrial Fibrillation) score is a widely used system for predicting the survival of patients with acute aggravation of chronic obstructive pulmonary disease (COPD). Evaluations of the predictive accuracy of DECAF have shown differing results. We performed this meta-analysis to evaluate the DECAF score as a survival predictor in patients with COPD.

Radiofrequency Ablation with Continued EGFR Tyrosine Kinase Inhibitor Therapy Prolongs Disease Control in EGFR-Mutant Advanced Lung Cancers with Acquired Resistance to EGFR Tyrosine Kinase Inhibitors: Two Case Reports.

Objective: Lung cancer remains the leading cause of malignant tumor-related death globally. There is mounting evidence that a large proportion of patients harboring epidermal growth factor receptor (EGFR) mutation and treated with EGFR TKI experience oligoprogressive disease. The optimal treatment strategy for these patients is undetermined.
