The techniques of treatment of carcinoma of the bronchus using 8 million volt rays are described. In a group of inoperable cases of carcinoma of the bronchus a three-year survival rate of 10% was obtained with squamous lesions, and in anaplastic and oat-cell lesions the three-year survival rate was 4%. The factors affecting the prognosis are described and also the palliation achieved.
