Overview
Natural history
- Malignant transformation of primordial germ cells that inappropriately migrated during development (either failing to migrate into or out of an area) are the originators of germinomas. There is no histologic differentiation whereas nongerminomatous germ cell tumors display a variety of differentiation.
Complications
Prognosis
- Intracranial germinomas have a reported 90% survival to five years after diagnosis.[1] Near total resection does not seem to influence the cure rate, so gross total resection is not necessary and can increase the risk of complications from surgery. The best results have been reported from craniospinal radiation with local tumor boost of greater than 4,000 cGy.
