Treatment of Childhood Mature and Immature Teratomas

For information about the treatments listed below, see the Treatment Option Overview section.

Treatment of newly diagnosed mature teratomas includes the following:

  • Surgery to remove the tumor followed by observation.

Treatment of newly diagnosed immature teratomas includes the following:

  • Surgery to remove the tumor followed by observation for stage I tumors.
  • Surgery to remove the tumor for stage I–IV tumors. In young children, surgery is followed by observation; the use of chemotherapy after surgery is controversial. In adolescents and young adults, chemotherapy is given after surgery.

Sometimes a mature or immature teratoma also has malignant cells. A teratoma with malignant cells may need to be treated differently.
