Abstract
BACKGROUND: The development of central airway obstruction during malignant diseases is an important cause of morbidity and mortality. Endobronchial therapies can decrease the patient's symptoms and improve quality of life. Here, we compare airway recanalization methods: argon plasma coagulation with mechanical tumor resection (APC + MTR) and cryorecanalization (CR efficiency, complications, restenosis rate, and time to restenosis) in patients with malignant exophytic endobronchial airway obstruction. METHODS: A total of 89 patients were included who were admitted to our hospital between 2005 and 2012. The data were analyzed retrospectively. Initially, a CR procedure was performed in 52 patients using rigid bronchoscopy under general anesthesia; the APC + MTR procedure was performed in 37 patients with malignant airway obstruction. RESULTS: The airway patency rate with APC + MTR was 97.3% (n = 36) and CR was 80.8% (n = 42). The APC + MTR procedure was more effective than CR for recanalization of malignant endobronchial exophytic airway obstruction. Additionally, the achievement rate of airway patency with APC + MTR was significantly higher in tumors with distal bronchial involvement. There was no statistically significant difference between groups in terms of complications, restenosis rate, and time to restenosis. CONCLUSIONS: The APC + MTR procedure is preferred over CR to introduce and maintain airway patency in patients with malignancy-related endobronchial exophytic airway obstruction.
