[Endobronchial intraluminal brachytherapy for patients with tracheobronchial carcinoma with high dose-rate 192-Iridium remote afterloading method].
Endobronchial intraluminal brachytherapy was conducted for 5 patients with tracheobronchial carcinoma using 192Iridium high dose-rate afterloading machine (microSelectron HDR) and guide tubes of 1.9 mm in outer diameter. Four patients with bronchial non-small cell carcinoma and one with tracheal adenocarcinoma were applied, and a dose of 6 Gy/Fr. at points 1 cm from the source once a week, and a cumulative dose of 18 Gy/3 Fr. was delivered. Guide tubes could be placed up to 3 tubes via the vocal airway, and new computer planning system could afford to calculate dose from independent lining of the source into optimization. This could be done with safety, and no remarkable acute side effects were observed attributable to this method.
