Treatment of Newly Diagnosed Central Malignant Germ Cell Tumor People With Teniposide Injection Combined With Cisplatin.

The subjects received an injection of teniposide combined with cisplatin every 3 weeks for one cycle. The teniposide dosage was 300 mg/m2, administered continuously over 3 to 5 days, each time with 500 ml of normal saline through intravenous drip; the cisplatin dosage was 75 mg/m2, also administered continuously over 3 to 5 days, for a total of 4-6 cycles. Radiation therapy was conducted according to standard practices after chemotherapy.
