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

  • Generally, germinomas are associated with an excellent prognosis. Intracranial germinomas have a reported 90% survival to five years after diagnosis.[1]

The 10-year survival of germinomas is 70%.

The prognosis of various germ cell tumors is shown below in a tabular form:

Type of tumor 5-year survival rate
Germinoma
  • 70-90%
Mixed germ cell tumors
  • 60-80%
Nongerminomatous germ cell tumors
  • 30-50%
