High-dose thiotepa with autologous bone marrow rescue in recurrent malignant oligodendroglioma: A case report

High-dose thiotepa with autologous bone marrow rescue is a new and promising treatment modality in several kinds of solid tumors. We used this regimen in a pediatric patient who had the third recurrence of his malignant oligodendroglioma of brain that developed during 8 in 1 chemotherapy. We achieved complete response after a total dose of 1125 mg/m² of intravenous thiotepa. Good penetration into the CNS renders thiotepa potentially useful for chemosensitive brain tumors, and one course of high-dose thiotepa can be administered with acceptable toxicity by utilizing autologous bone marrow rescue.
