In comparison with operation, we observed more recurrence after external beam radiotherapy for roentogenographically occult lung cancer. Then, since July 1991, we have treated that lung cancer, with external beam radiotherapy and intraluminal afterloading irradiation using ^<192>Iridium thin wire. The indication of this method is roentogenographically occult lung cancer, diagnosed inoperable for their respiratory function, age, and complications, and for refusal of operation. Up to Sept. 1994, 36 patients (44 lesions) were treated by this method. The follow-up period ranged from 0 to 41 months. Recurrence occured in 2 cases on whom an operation was done:one is well and the other is alive with disease. Radiation pneumonitis required treatment was observed in another 2 cases. Other recurrence or severe complications from irradiation have not been observed. We think this treatment is effective for roentogenographically occult lung cancer.
