    Abstract:
    The Radiation Therapy Oncology Group (RTOG) investigated the use of misonidazole as an hypoxic cell sensitizer in a Phase III prospective randomized trial employing radiotherapy, 600 cGy twice weekly to a total of 3600 cGy with and without misonidazole in the treatment of locally advanced non-metastatic squamous cell, adeno, or large cell carcinoma of the lung. Between January 1980 and July 1983, 117 patients from 21 institutions were enrolled. One-hundred eight patients were evaluable; 53 in the combined treatment arm and 55 in the radiation alone arm. Grade 3 or worse complications associated with radiation occurred in 17% of patients. Esophageal toxicity accounted for the majority of complications. Two (4%) patients in the radiotherapy plus misonidazole group experienced grade 3 peripheral neurotoxicity. Complete or partial responses were produced in 58% of the patients with radiotherapy alone and 36% of those treated with radiotherapy plus misonidazole (p = 0.08). At the time of first progression, over 50% of the patients had persistent local disease. Median survival was 7 months regardless of treatment. Misonidazole in the dose and schedule employed did not enhance the effect of radiotherapy on either local tumor control or overall survival in patients with advanced lung cancer.
