title: Radiotherapy of intracranial germinomas.
abstract: Between 1980 and 1992, 32 patients with intracranial germinomas were treated with radiation. All patients were confirmed histopathologically prior to treatment. Of the 32 intracranial germinomas reviewed, 14 were located in the suprasellar region, 12 in the basal ganglia and thalamus, four in the pineal, and two in both the pineal and suprasellar regions. Three patients had subarachnoid seeding. Craniospinal irradiation was undertaken for 29 patients. The median dose of 54 Gy was delivered to the tumor bed, 36 Gy to the whole brain and 24 Gy to the spinal axis. Five and 10-year survival rates were 96.9 and 96.9%, respectively. Local control was achieved in all patients except one who died of persistent tumor after 2 months following radiotherapy. No intracranial recurrence or spinal metastasis were found. Tumor site did not relate to the prognosis. One patient developed severe intellectual deterioration, three patients had vertebral growth impairment. The present study confirms the excellent result with radiotherapy alone for patients with germinomas.
