Prophylactic treatment of known ifosfamide-induced encephalopathy for chemotherapy with high-dose ifosfamide?
We report about a case of advanced Ewing sarcoma in a 30-year-old woman. Initial treatment was started according to the Euro-Ewing 99 protocol. During the initial therapy, an ifosfamide-induced encephalopathy occurred as status epilepticus. Because of cerebral toxicity, the following chemotherapies went without ifosfamide. During final radiotherapy multiple lung metastasis were diagnosed. After two cycles of chemotherapy with cyclophosphamide and topotecan (no response), left thoracotomy, and palliative pneumectomy, the patient was transferred to our ward for further treatment. Undergoing two cycles of chemotherapy with ifosfamide 4 g/m(2) intravenously for 3 consecutive days followed by high-dose chemotherapy (HDCT) according to the ICE-regimen (ifosfamide 2 g/m(2), carboplatin 200 mg/m(2), and etoposide 2 x 100 mg/m(2) intravenously for 6 consecutive days), and peripheral blood stem cell transplantation (PBSCT), complete remission was achieved. Under preventive therapy with methylene blue, thiamin, and glucose 5% infusions, no encephalopathy occurred.
