Abstract
Germ cell tumors account for a 3% mortality rate of childhood malignancies. The combined chemotherapy, vinblastine, bleomycin and cis-platinum, is probably associated with more toxicity and treatment-induced mortality in children. Based on pharmacokinetic findings concerning the renal elimination of bleomycin and the well known cis-platinum nephrotoxicity, these two drugs were given sequentially. In addition, the cumulative dose of bleomycin was limited to 180 mg/m2. 61 patients entered the trial whereby 42 of these are evaluable. The chemotherapeutic regimen was well tolerated and was completed in 19 patients without treatment induced mortality and without evidence of pulmonary fibrosis. The treatment regimen seems to be successful despite the relatively low cumulative doses of vinblastine and bleomycin, as only 4 of 19 patients relapsed after a median observation period of 12 months.
