Treatment and Clinical Outcomes of Patients with Teratoma with Somatic-Type Malignant Transformation: An International Collaboration

Abstract

Less heavily pretreated teratoma with malignant transformation with a gonadal primary tumor and nonprimitive neuroectodermal tumor histology appears to be associated with longer overall survival. Generally, teratoma with malignant transformation had a worse prognosis than germ cell tumor. Uncertainties persist regarding optimal chemotherapy.
