Thirty-seven patients with tracheobronchial lesions by malignant tumor were treated with Nd-YAG laser. Thirty-seven patients were twenty-three males and fourteen females and ages ranged from 34 to 79 years. Diseases included were primary tracheal tumor in 3 cases, lung cancer in 16 (8 squamous cell carcinoma, 5 adenocarcinoma, 2 large cell carcinoma, 1 small cell carcinoma), cancer of adjacent organs in 9 (5 thyroid cancers, 4 esophageal cancers), and metastatic cancer to the lung or mediastinal lymph nodes in 9 (4 renal cell carcinoma, 2 thyroid cancer, one patient respectively, colon cancer and breast cancer). Intermittent irradiation of YAG laser was done for 0.5 second at 30-40 Watt through flexible bronchoscope under local anesthesia. It was repeated 1 to 41 times (mean 4.1 times) and energy amount was 148 Joules to 18,513 Joules (mean 3,305 J). The result was; stenosis disappeared in 22 cases (59.4%), improved in 14 (37.8%), and in one case YAG laser therapy discontinued due to intractable bleeding. The Nd-YAG laser therapy for tracheobronchial lesions by malignant tumor is very useful to improve dyspnea or atelectasis.
