[Application of Ethyol during chemotherapy in patients with impaired kidney function. Description of three cases].

Nephrotoxicity is observed in 30% of patient's treated with chemotherapy schedules based on cisplatin analogues. Ethyol (amiphostin) was used as a protectant of kidney in 3 paediatric patients with neoplastic disease. Two patients suffered from Wilms tumour. One of them, a 5 month old boy presented with agenesis of the right kidney and stage II tumour in the left kidney. Bilateral Wilms tumour was recognised in a 6 year old girl. In both cases glomerular filtration was diminished. The third patient was a girl aged 5 who had isolated relapse of neuroblastoma in the central nervous system. Primary treatment caused nephrotoxic complications such as Fanconi syndrome and diminished glomerular filtration (66 ml/min). In these 3 cases Ethyol was used every lime before analogues of cisplatin were given. Tolerance and the effect of this protectant were good.
