[Bronchial cancer: radiation therapy].

Postoperative radiotherapy as a routine procedure has failed to show any benefit in prospective randomized studies. Local failure was diminished, but survival rates remained unchanged, probably because of radiation complications. By improvement of radiation techniques, however, reduction of single doses and total dose and focusing postoperative irradiation of lung cancer to high risk cases (N2, T4) survival rates with postoperative irradiation are about 20% after 5 years. The results of 191 treated patients are demonstrated.
