Immature Ovarian Teratoma
NCI Definition: A malignant germ cell tumor arising from the ovary. It usually affects females in their first two decades of life. It contains variable amounts of immature embryonal tissues. Based on the amount of immature neuroepithelial component, immature teratomas are graded from 1 to 3. The stage and grade of the tumor and the grade of the metastatic tumor are the important factors that predict prognosis. The use of cisplatin-based combination chemotherapy has significantly improved the survival rates of the patients. 
There is 1 clinical trial for immature ovarian teratoma, of which 1 is open and 0 are completed or closed. Of the trial that contains immature ovarian teratoma as an inclusion criterion, 1 is phase 3 (1 open).
Bleomycin, etoposide, and observation are the most common interventions in immature ovarian teratoma clinical trials.
