[The results of the use of bleomycin and its analogs in the VAB-6 protocol in treating testicular tumors].

Efficacy and toxicity of VAB-6 combinations with bleomycin, bleomycetin or peplomycin were studied in treatment of 77 patients with metastases of germ-cell tumors: testicle tumors in 71 patients and extragonadal tumors in 6 patients. After the chemotherapy complete regression was observed in 37 patients (48.7 per cent). In 44 patients (57.1 per cent) residual metastases after the chemotherapy were resected. The frequency of complete regression after using the VAB-6 combinations with bleomycin, bleomycetin and peplomycin amounted to 58.8, 61.5 and 47.1 per cent respectively. The treatment results depended on the disease extent. When the disease extent was minimal complete regression was observed in 87.5 per cent of the patients. The respective figures for the disease moderate and significant extents were 66.7 and 37.8 per cent. During the average observation period of 22.1 months (7-40 months) 39 patients survived and had no signs of the disease. The combinations markedly differed in their toxicity.
