title: [A case of leukoencephalopathy caused by HCFU].
abstract: After a hysterectomy, a bilateral salpingo-oophorectomy, two courses of intra-peritoneal chemotherapy of Cisplatinum, Carmofur (HCFU, 600 mg/day [per os]) were given a patient who had ovarian granulosa cell tumor (malignant, stage Iai). Dizziness and loss of consciousness developed about 60 days after administration of HCFU, and leucoencephalopathy was diagnosed. A CT revealed a diffuse low density area in the white matter of the cerebrum. Myelin Basic Protein in the spinal fluid was found to amount to 9.8 mg/dl, which in norm. person is less than 4.0 mg/dl. Also, it showed parallel changes with the course of the clinical findings. HCFU easily dissolves to fat and changes to 5-FU without enzymes in the liver cell. Further HCFU also passes through Blood Brain Barrier to Produce 5-FU and its derivatives, in which the alpha-Fluoro-beta-Alanine is thought to be the culprit that brings on leucoencephalopathy. Even so, HCFU should be dosed when needed in spite of this risk. Other 5-FU modifiers also have been reported to produce the same effect in several cases.
