RESUMEN
Purpose:To study the methods of treatment of spinalcord implanation medulloblatoma with combined chemotherapy. Methods:Teniposide (VM 26) 100 mg/day (dissolving in 250 ml physiological saline(N.S.)) was injected intravenously in 3 consecutive days. And it was repeated after a 7 day interval, and bleomycin A 5(PYM) 4 mg (in 250 ml N.S.) was intravenously injected twice a week. Methotrexate (MTX) 10 mg (in 5 ml N.S.) and dexamethsone 3 mg were injected intrathically once a week. The whole treatment included 5 courses and lasted about one and half month.Results:The study involved 6 cases. MRI, whick were performed 2 weeks after the treatment, showed tumors disappeared in 2 cases and 80% shrunk in 4 cases. The tumors completely disappeared after repeated treatments in the 4 cases. Conclusions:Combined chemotherapy is an efficient alternative treatment for spinalcord implanation medulloblatoma.
