[Results of ortho- and megavolt therapy of inoperable bronchial carcinoma].

Survival rates of patients with inoperable, histologically verified bronchial carcinoma are compared as to orthovoltage or megavoltage radiation therapy. With megavoltage therapy, better survival rates are obtained after one or two years; later on, an approximation of the comparison groups is to be observed with regard to life expectancy. The improvement in one-year and two-year survival rates does justify the application of megavoltage therapy.
