Treatment of intracranial germinoma

In 31 patients with intracranial germinoma who received radiotherapy, 15 were operated on, and 13 were treated with CSF shunt (7) and external ventricular drainage (6). After radiotherapy, clinical symptoms were improved in 93.5% of the patients. Follow-up of 16 patients for 2 to 14 years showed better results. We consider that initial treatment with radiotherapy may be appropriate for germinomas because of its high radiosensitivity. If hydrocephalus developed, external ventricular drainage combined with radiotherapy was performed, but shunting operation might be avoided because of potential peritoneal seedings of germinomas. In addition to chemotherapy, re-irradiation is an effective method for recurrent germinoma.
