[Intraoperative radiotherapy of lung cancer. Report of 31 cases].

Intraoperative radiotherapy (IORT) was done in 31 patients with non-small cell lung cancer from July 1989 to July 1990. Most of them (21/31) were found to have a tumor of stage III. A radiation dose of 5 to 25 Gy was delivered after pulmonary resection to residual tumor or subclinical tumor lesion. The postoperative course was uneventful and no clinical complication developed in all patients. The clinical significance, technique, indications, doses and possible complications of IORT were discussed.
