All cases of bronchogenic carcinoma treated with curative intent over an eight-year period were reviewed. Most were treated with 12 X 400 rad in 32 days using 60Co, a schedule designed to optimize the radiation-sensitizing properties of hyperbaric oxygen. While O2 gave no obvious benefit, overall four-year survival was 10.6% and that of patients with good prognostic indicators was 18%. No radiation myelitis was observed. This protocol delivers an adequate tumor dose and appears to be tolerated well by most patients.
