title: Pineal region tumors: analysis of treatment results.
abstract: This article represents a review of 32 patients with pineal region tumors seen and treated at the University of Michigan Medical Center from January 1950 to December 1980. All patients presented with manifestations of increased intracranial pressure: limitation of the upward gaze (Parinaud's syndrome), hydrocephalus and a mass in the posterior aspect of the third ventricle. The tumor was demonstrated by pneumoencephalography, ventriculography, angiography or CT scans. Ventricular decompression was performed in all patients. Eighteen of the 32 patients (56%) had a histological diagnosis of germinoma, one patient had a diagnosis of hamartoma; no histological diagnosis was obtained in the remainder of the patients. Twenty-seven patients received post-operative irradiation. Irradiation dosage ranged between 30 and 55 Gy. The overall 10 year survival for evaluable patients was 16/24 (67%). The low incidence of spinal cord metastasis in these patients does not justify routine use of spinal irradiation.
