[Bronchoscopic treatment of malignant central airway obstruction: A cohort study, long-term survival and...

Interventional bronchoscopy is now the standard treatment for tracheobronchial narrowing due to tumor. The objective of our study was to analyze long-term survival and complications occurring in patients with malignant airway obstruction.

We retrospectively studied the data from 93 patients treated between 2008 and 2019.

One hundred and eleven therapeutic bronchoscopies were performed. Sixty-seven patients had primary lung cancer, in 17 had tumors of another origin and 9 patients had benign or local lung tumors. Thulium laser was frequently used prior to tumor enucleation and to restore hemostasis. Seventy-one silicone stents were inserted. The death rate at the time of the procedure was 1.8% and immediate complication occurred in 9.9% of the patients. Long-term survival was significantly better for patients with cancer from other origins than in those with primary lung cancer (615.5days versus 177.9days). On the other hand, there was no significant difference in long-term survival between patients with locally advanced and metastatic lung cancer with endobronchial lesions treated by stent and those who were not (234.2days versus 164.6days). All patients with benign or with locally malignant tumors were still alive.

Therapeutic bronchoscopy increases the long-term survival of patients with malignant airway obstruction. The risk-benefit ratio was favorable.
