| Abstract: | The efficacy of the chemotherapy of 16 patients with metastases of malignant tumors of the testicle was studied. The chemotherapy included vinblastine, platidiam and bleomycetin. The latter was used in a dose of 10 mg daily intramuscularly or as long-term intravenous infusions. As a result of the treatment complete and partial regression of the tumors was observed in 5 (31 per cent) and 4 (25 per cent) patients, respectively. Leukopenia was the main side effect. By present the total doses of bleomycetin had amounted to 250 mg for 4 patients and to 300-350 mg for 7 patients. No signs of pulmonary toxicity were observed with the use of these doses. The problem of clinical studies of bleomycin analogs is discussed. |
