| Abstract: | The results of treatment of 23 children at the age of 7 months to 11 years suffering from neuroblastoma are presented; 22 patients with tumors, relapses or metastases were subjected to the treatment and 1 child was treated prophylactically after radical operation. Four patients were subjected to roentgen therapy in addition to the treatment with rubomycin. The antibiotic was administered intravenously in doses of 0.7--1.5 mg/kg in 1--3 days or daily. The caurse dose (3--12 mg/kg) was determined by the treatment efficiency and the side reactions. The objective effect was observed in 68 per cent of the patients, including the pronounced objective effect (marks 3 and 2) in 41 per cent of the cases. Leucopenia (less than 4000 cells in 1 mm3 of the blood). thrombocytopenia, vomiting (or nousea) and changes in the ECG were registered in 20 (87 per cent), 4,9 and 2 patients respectively. When the results of the treatment were positive, repeated courses of the therapy within 1.5--2 years were carried out; 18 patients died within 4 months to 2 years after the first course of the treatment with rubomycin because of the disease development. No signs of the disease were observed in 4 children with in 3--6 years of observation. |
