title: BCG immunotherapy of lung cancer in a district oncology dispensary. I. Study of 860 patients with histologic diagnosis.
abstract: The investigation refers to lung cancer patients registered in an oncology dispensary from 1965 to 1975. The conventional treatment (surgery, radiotherapy and chemotherapy) has covered 35.9% of all patients, whereas immunotherapy with BCG or with its soluble fraction has been applied in 46.2% of them. Immunotherapy has mainly been applied to epidermoid carcinoma and large-cell carcinoma. Comparing the survival of immunotherapy treated with non-immunotherapy treated patients it was found that in Stage I-II group the difference in favor of immunotherapy was significant in the second year of observation and in Stage III group a significant difference was found in all observation periods (1-5 years). In Stage I-II the 5-year survival rate of immunotherapy treated patients (13.2%) was similar to the survival rate of operated patients (13.7%). Immunotherapy in large cell carcinoma showed significantly better results than immunotherapy in epidermoid carcinoma. Immunotherapy with BCG and F70 was applied as an independent treatment of lung cancer. When applied to patients primarily operated, radiation or chemotherapy treated, the survival was significantly higher than the survival of patients submitted to conventional treatment or to immunotherapy separately.
