title: Primary intracranial germ-cell tumors. A retrospective analysis with special reference to long-term results of treatment and the behavior of rare types of tumors.
abstract: Thirty cases of primary intracranial germ-cell tumors were reviewed with reference to the effect of treatment. Histologically, there were 23 pure germinomas, while the remaining tumors had more unusual histology; 3 of these were teratomas, and 4 germ-cell tumors with the admixture of yolk sac tumor (YST) or embryonal carcinoma (EMC). Three of these rare cases are presented. The performed surgery and radiotherapy, seemed adequate for pure germinomas, and all these cases lived tumor-free after an observation time of 13 to 139 months although 4 patients developed intellectual retardation or cerebral dullness after radiotherapy. Four cases with YST and EMC elements, indicated by the elevation of AFP and HCG values in serum, were resistant to radio- and chemotherapy and developed, despite surgically total removal of the tumor, intra- or extracranial metastases. A review of the literature is included.
