Survival and prognostic factors for patients with malignant central airway obstruction following airway metallic stent placement.

Background: There have been many studies on the effectiveness and complications of airway stent, but few had focused on factors that affect survival after stent placement. This study intended to assess the factors associated with the survival in patients with malignant central airway obstruction (MCAO) after airway metallic stent placement.
