[A case report of advanced malignant mixed germ cell tumor of parasellar origin indicating marked efficacy of a salvage combined chemotherapy of CDDP and etoposide and subsequent chemotherapy using oral etoposide].

A case of a 13-year-old boy with malignant mixed germ cell tumor of parasellar origin was reported. After partial removal of the tumor, combined chemotherapy (using cisplatin, vinblastine and bleomycin: PVB therapy) and irradiation were performed, and the tumor was reduced to under one tenth. In spite of PVB maintenance chemotherapy, it became refractory later. The patient was then treated with both CDDP 20 mg/m2 daily for 5 days and etoposide 100 mg/m2 for 1, 3, 5 days. After this one course, the tumor was diminished. Oral etoposide was administered at our outpatient department, and the boy was free of disease for six months.
