Introduction. - Due to ifosfamide urotoxicity, encephalopathy is a frequent
complication accompanying treatment with this drug. The various clinical,
physiological and therapeutical aspects of ifosfamide-related encephalopath
y are reviewed. We report two cases and review current literature.
Exegesis. - Ifosfamide-related encephalopathy has polymorphous and non-spec
ific clinical picture. The disease severity is variable, as related deaths
have been reported. Clinical signs disappear with treatment discontinuation
. Routes of administration, doses, tumoral site and gender have been implic
ated in the disease physiopathology. Admittedly metabolite mitochondrial to
xicity would be the underlying mechanism. Treatment would be based on intra
venous methylene blue. A clinical trial aimed at studying prophylaxis is in
progress. A few number of patients have been cured until now.
Conclusion. - Further studies are required to confirm the involved physioph
athological mechanisms and methylene blue effects. (C) 1999 Elsevier, Paris
