<p>Endobronchial tumors can cause obstruction of the tracheobronchial tree regardless of their benign or
malignant character. Tumor removal is thus considered the first treatment of choice to improve respiratory
status to dilate and maintain the airway. In particular, treatment of benign airway tumors should employ the
method with minimal stress. In patients with inoperable tumors we frequently regard endoscopic treatment as
the first treatment of choice, but the indications and decisions regarding the method require careful
consideration. Good indications for endoscopic treatment include tumors in which the distal margins can be
endoscopically evaluated, and are located within the tracheobronchial tree, as far as the subsegmental
bronchi, pedunculation, which can facilitate snaring and resection, if the lesions are not broad based,
extend across multiple cartilaginous rings, and if there is no extramural tumor invasion. Furthermore, since
a few cases show recurrence or malignant transformation even after resection, careful periodical observation
of the resection stump with the bronchofiberscope (BF) is necessary. For this overview study, we selected a
variety of interventional therapies for patients compromised due to advanced age or poor general status.</p>
