We applied mini-tracheostomy for a ready access route, and a torque controlled technique for easy insertion of the endobronchial applicator.
Eight patients with tracheobronchial cancer invasion were treated with endobronchial brachytherapy of 18-30 Gy/3-5 fractions/1.5-2.5 weeks (median 24 Gy/4 fractions/2 weeks) at reference points of 5 mm from the bronchial surface.
The averaged individual irradiation and single session times were 4 min and 24 min, respectively.
There were no procedure-related complications.
These technical improvements may facilitate flexible fractionated dose prescriptions.
